Introduction: Transient periosteal hyperostosis with dysproteinemia, also named Goldbloom syndrome (GS), is a rare pediatric disease characterized by recurrent crisis of bone pain, fever, increased inflammatory markers and dysproteinemia. From 1966 only few cases have been reported in the English literature.

Objectives: To better define the clinical and epidemiological features of GS.

Methods: We report clinical, laboratory and radiological features of our patients in Table 1, comparing with the English literature.

Results: Case 1 was a 9-year-old girl who presented daily crisis of bone pain at the lower limbs, associated with fever spikes, limping and nocturnal awakenings. Physical examination was normal. Laboratory tests showed mild anemia, thrombocytosis, increased inflammatory markers and high antibody levels against streptolysine O and DNase-B (ASO 4280 IU/ml and ADN-B 6310 UI/ml, respectively). Throat swab was positive for group A β-hemolytic streptococcus (GAS). Unusual dysproteinemia, characterized by hypoalbuminemia with increased a1, a2 and g globulinemia, was noted. X-ray evaluation of the lower limbs showed increased bone density at femurs and tibias with signs of periostitis: on STIR sequence MRI these bones presented areas of hyperintense signal. Bone biopsy revealed a thickened periosteum that was strongly adherent to the underlying tissue. Histopathologic study showed signs of chronic inflammation. Steroid treatment was started, leading to a prompt resolution of the clinical picture within few days.

Case 2 was a 6-years-old girl who developed, two weeks after an untreated febrile pharyngitis, daily attacks of severe pain at ankles with fever. Joint examination was normal. Throat swab was positive for GAS. In the following weeks, recurrent crisis of bone pain persisted with a severe weight loss. She was hospitalized and laboratory tests showed mild anemia, thrombocytosis and unusual dysproteinemia with hypoalbuminemia and high a1, a2 and g globulinemia. Inflammatory markers and antibodies against GAS were elevated (ASO 775 IU/ml, AND-B 1660 U/ml). STIR sequence MRI showed hyperintense areas at the femurs, tibias, humerus and ulnas, associated with a thickened pretibial soft tissue. Bone marrow biopsy showed signs of chronic inflammation. A short cycle of steroids was administered with rapid resolution of symptoms, turning off inflammatory markers. Immaging became normal after three months.

Conclusion: Our patients fulfill the GS features with evidence of previous GAS infection. Our patients lived in the same area of Northern Italy and presented the onset of GS a week apart. Our experience suggests that a timely diagnosis and a short cycle of steroid may rapidly change the history of GS.

Introduction: In 2015 the historic Jones criteria for the diagnosis of Acute Rheumatic Fever (ARF) were revised introducing two different sets of criteria for low-risk and for moderate/high-risk populations (according to ARF incidence). In Italy the exact ARF incidence is unknown but small regional or local reports suggest an incidence of 2-5/100.000 per year, suggesting that our population might be considered at moderate risk for ARF.

Objectives: To evaluate the performance of the revised Jones criteria in a retrospective population and to compare it with the performance of the previous version of Jones criteria.

Methods: We conducted a retrospective study on 288 patients with ARF (108 female; median age 8.5 years, IQR 7.1-10.3) diagnosed from 2001 to 2015 in a Pediatric Rheumatology Division by pediatric rheumatologists, discharged with an ICD 9 code consistent with ARF. We retrospectively applied the two sets (for low-risk and for moderate/high-risk) of the 2015 revised Jones criteria and the 1992 version of the Jones criteria.

Results: Of 288 patients, 253 (87.8%) met the 1992 version of the Jones criteria, 237 (82.3%) met the revised criteria for low-risk populations and 259 (89.9%) for moderate/high-risk populations. None of these differences was significant. Prevalence of major and minor criteria is shown in Table. With the exception of difference in arthritis, the 1992 version and the 2015 revised version did not show major differences. Of the 288 patients with a clinical diagnosis of ARF 29 did not meet any version of the Jones criteria. Patients in this group presented with isolated chorea or silent carditis without other manifestations.

Prevalence of the clinical characteristics and comparison among the 1992 version of Jones criteria and the 2015 revised Jones criteria (low risk and moderate-high risk populations):

Conclusion: The revised Jones criteria for low-risk populations are slightly more sensitive than the 1992 version of Jones criteria, while the revised Jones criteria for moderate/high populations are slightly less sensitive than the 1992 version. In this population, the revised criteria did not substantially modify the diagnosis of ARF. Approximately 10% of patients presented with isolated chorea or silent carditis.

P383 Restrospective view of primary raynaud’s phenomenon in childhood

Enes Turan, Sara Sebnem Kilic

Pediatric Rheumatology, Uludag University Medical Faculty, Bursa, Turkey
Presenting author: Sara Sebnem Kilic

Introduction: Raynaud’s phenomenon (RP) refers to transient vasospasm of peripheral arteries and arterioles, usually involving peripheral small vessels of the fingers or toes and resulting in a triple-colour change starting with pallor and followed by cyanosis and erythema. Attacks are typically triggered by cold or emotional stress. The diagnosis of RP can be made on the basis of the patient’s clinical symptoms. Primary RP occurs without underlying disease and is considered a benign. Connective tissue diseases are the most common cause of secondary RP. Objectives: Detailed history, physical, and laboratory findings of the patients with primary RP were evaluated restrospectively.

Methods: Data collection was performed via the patient files. The study was approved by the Ethical Committee of the Uludag University Faculty of Medicine.

Results: Out of the 58 patients, 38 were girls whereas 20 were boys. The patients’ boy/girl ratio was 1.9 (38/20) and their ages ranged from 6 to 21 years (median:16 years). The median age at onset of complaints due to RP was 13 (minimum:2, maximum:17), median age at diagnosis:15 (minimum:3, maximum:17). In 37.9% cases (n = 22) There were similar complaints in first-degree relatives in 37.9% of patients. The most common symptom was feeling cold in the extremities ends (100%), followed by pain (87%) and tingling sensation (70.7%). While 38 patients(65.5%) had biphasic colour changes, 20 (34.5%) had triphasic colour changes. Triphasic colour change was statistically significant with high incidence (p = 0.026) in cases with ANA positivity and family history. Low titer positive ANA was present in 14 patients(24.1%). Presence of migraine in 29,3% of the cases was the most common disease associated with RP. Migraine was significantly more frequent in the girls compared to the boys (p = 0.02). Furthermore, cases with migraine had a significant lower hemoglobin levels and significant higher mean platelet volume. Apart from preventive measures, calcium channel blockers (CCB) were the most used drugs (n = 32, 55.2%) and were beneficial in 78.1% (25 out of 32). Nitroglycerin patch was applied to the rest of patients (n = 26, 44.8%), which was useful to relieve the symptoms in 50% of them. Sildenafil was used in one patient who was resistant to both of the drugs and the result was positive.

Conclusion: There is very limited data concerning childhood RP. In previous studies conducted in children there is no data on association between RP and migraine. Anemia in patients with RP was thought to be a predisposition to migraine development. Calcium channel blockers were found to be more effective than nitroglycerin patch treatment. Further studies with a greater number of patients are required in order to confirm our results.

Presenting author: Yasuhiko Itoh

Introduction: Anti-Ro antibodies are found in children with either Sjögren’s syndrome (SS), systemic lupus erythematosus (SLE) or, occasionally, chronic nonspecific complaints such as fatigue and low-grade fever. We have reported that about 10% of children with chronic nonspecific complaints and with positive antinuclear antibodies were positive for anti-Ro antibodies.

Objectives: Although a few of them showed positive lip biopsy findings equivalent to that of SS (subclinical SS), the majority of such children exhibited no evidence of SS. To clarify the pathogenic role of anti-Ro antibodies in various conditions and the future development of dryness, those children have been followed for more than 10 years, both clinically and immunologically.

Methods: The patients included in this study were as follows: 1) 27 children with chronic nonspecific complaints, with anti-Ro antibodies, and with negative lip biopsies; 2) 10 children with chronic nonspecific complaints, with anti-Ro antibodies, and with positive biopsies; 3) nine children with SLE and with positive anti-Ro antibodies; 4) three children with MCTD and with positive anti-Ro antibodies. They have been followed for more than 10 years. Anti-Ro antibodies were measured by using either the Ouchterlony, ELISA, western immunoblot or, in some cases, RNA-immunoprecipitation methods.

Results: Twenty-three out of 27 patients in group 1 showed no evidence of SS even after more than 10 years. Most of the patients in group 2 who had not been treated by immunosuppressants have gradually developed dryness. On the other hand, patients who had been treated have developed no or little dryness. Patients in the groups 3 and 4 have developed no dryness.

All patients in groups 3 and 4 had been treated by immunosuppressants against their basic diseases and developed no dryness. In the same way, most patients with only nonspecific complaints treated with immunosuppressants did not develop dryness.

Conclusion: These results suggest that there may be a chance to prevent SS with immunosuppressants in children with positive anti-Ro antibodies as long as the treatment is initiated before they develop dryness.

Presenting author: Ela Tarakci

Introduction: Juvenile idiopathic arthritis (JIA) is the most common chronic pediatric rheumatic disease. Depending on the underlying pathologies, the common symptoms of this disorder are the limitations of the upper extremity joint movement angles, muscle imbalance and the functional limitations caused by the contracture due to these patients. By utilizing exciting new sensor technologies, such as Microsoft Kinect, Nintendo Wii and Leap Motion, practical game based rehabilitation applications have been becoming popular in the current.

Objectives: The aim of this study was to investigation of effectiveness of invented rehabilitative games using The Leap Motion Controller (LMC) for hand rehabilitation in patients with JIA.

Methods: 18 patients with JIA (14 girls, 4 boys), age range 8-18 participated in this study. Range of motion (ROM) of hand, grip strength, functional ability, fatique and quality of life were assessed with a goniometer, hand dynamometer, Childhood Health Assessment Questionnaire (CHAQ), Numeric Rating Scale (NRS), and the Pediatric Quality of Life Inventory (PedsQL), respectively. In order to improve hand functions, two games were invented with hand free LMC by our team. One of the games, “Leapball” was invented as picking the ball and throw to the basket. The game is to ensure the activities of repeated hold and release by simulating the hand grip function. The other game, “CatchAPet” is to intend touching the rabbits going out its burrow for simulating wrist flexion and extension. The patients completed a 8 week individually planned leap motion based exercise programme 3 times a week at the department of physical therapy and rehabilitation. Duration of the each treatment session was 30-45 minutes. Parameters of the games (Time, size of ball, speed of rabbits) were adjusted according to patient’s functional ability and progressed during the treatment.

Results: The mean age and duration of disease was 12.22 ± 3.30 (age range 8-18), 7.28 ± 4.22 years, respectively. The means of the pre/post treatment scores of NRS fatigue were 6.11 ± 1.53 / 2.22 ± 1.21, PedsQL-patients 63.71 ± 18.13 / 85.93 ± 12.08, PedsQL-parents 57.63 ± 18.88 / 80.80 ± 13.21, CHAQ-total 1.36 ± 0.67 / 0.30 ± 0.28, CHAQ-pain 31.94 ± 30.49 / 6.94 ± 11.77, and CHAQ-well being scores were 55.28 ± 19.28 / 21.94 ± 15.44, respectively. Table 2 shows ROM of wrist flexion and extension, fingertip to palm distance, hand grip and pinch grips scores for pre and post treatment. Significant statistical differences were found between pre and post-treatment all outcomes. (p < 0.001).

Conclusion: The study demonstrated that participating in a 8-week individually planned leap motion based exercise programme improves the range of motion of hand, grip strength, fatigue, physical function and the quality of life in patients with JIA. We think that improvements of the results may base on realistic animations of hand, virtual environments, patient motivation, consistent visual feedback and feasible and easy progression options of the invented games.

Presenting author: Emily Wilson

Introduction: Lupus is a severe, autoimmune disease, potentially affecting any organ in the body. It is very rare in children and young people. As a regional service and the UK’s only ‘Centre of Excellence for Childhood Lupus’, our patients live across a large geographical catchment area. Many of the patients accessing our service report never having had the chance to meet another young person with the condition and how isolating this could feel. The mental health needs of young people with chronic health conditions are well known and potentially debilitating.

Objectives: We aimed to develop a series of day-long multidisciplinary “Lupus and You” workshops to be attended by young people with lupus and their families, within the Lupus Centre at Alder Hey Children’s Hospital. We wanted to continue to be responsive to the ongoing needs of our patients whilst also looking to intervene proactively to support them in developing resilience and coping strategies to minimise the impact of their condition on their lives.

Methods: 7 families participated in the first workshop which focused on two main themes; managing fatigue and research participation.

Fatigue was one of the most commonly reported concerns identified by young people and their parents on a routinely completed pre-clinic screening tool. A recent survey of young people with lupus suggested patients wanted to know more about research participation.

All participants completed a range of standardized measures to capture psychological well-being (including fatigue, emotional well-being, resilience and quality of life) at the time of attendance. Evaluations forms were given out to all attendees in order to review the day and identify areas for consideration within future workshops.

Results: Participants participated in exercises designed to facilitate sharing of difficulties as well as examples of strategies utilized to manage fatigue. The team’s psychologist, physiotherapist and occupational therapist also shared ideas and strategies for families to consider. Information about local and national research in paediatric lupus was shared in an interactive session.

High levels of fatigue were identified amongst lupus patients (mean score on the fatigue severity scale 5.1 (range 4 – 5.8) where people scoring above 3 points are considered to suffer with fatigue). Young people and their families reported increased confidence in managing fatigue when pre- and post-workshop data were compared.

Otherwise there was considerable variation in the extent to which young people were coping with having lupus. The results will be reviewed with the individuals and their parents in order to inform ongoing intervention and support.

Feedback from workshop evaluations indicated that attendees found the activities to be helpful and convenient to attend. Support for siblings, medication, and knowledge of common symptoms were identified as potential topics for future workshops.

Conclusion: The “Lupus and You” workshop allowed young people with lupus and their families to share experiences of managing this chronic illness, to develop supportive relationships whilst also developing resilience and practical strategies for living their lives fully despite their ongoing health needs.

Workshops such as this could be used as a forum to facilitate collection of important data from patients with rare diseases, whilst simultaneously benefitting patients and their families.

The workshops are being considered as part of a stepped-care model of psychological support offered to lupus patients.

Introduction: Juvenile idiopathic arthritis (JIA) is most common chronic rheumatic disease in childhood. The upper extremity involvement in JIA causes muscle imbalance, joint destruction, pain, stiffness and limitations on activities of daily living (ADL) in varying degrees. It has been reported that improvements of upper extremity functions were achieved by video-based games (VBG) in various disease groups.

Objectives: The aim of this preliminary study was to investigate effects of client-centered task-oriented activity training (TOAT) with VBG on upper extremity functions and activity performance in children with JIA.

Methods: 23 patients (19 girls, 4 boys) with JIA (7 oligoarticular, 16 polyarticular) have upper extremity involvements, participated in this study. Muscular strength was measured by using a portable digital handheld dynamometer. Also, hand grip and pinch strength evaluations was done by a dynamometer and pinchmeter. ADL was evaluated by Duruoz Hand Index (DHI) and Childhood Health Assessment Questionnaire (CHAQ). Activity performance was performed by Jebsen Hand Function Test (JHFT). Also, activity performance and satisfaction were measured by The Canadian Occupational Performance Measure (COPM). Five most important problems of activity performance were determined with the patient and his/her parents. Fatigue severity was measured by Numeric Rating Scale (NRS). We have created training protocol with Xbox 360 games. We prefered ‘Dance Central2’, one of the Xbox 360 games, for warming (macerana dancing, 10 minutes). Other games, ‘Fruit Ninja’, ‘Table Tennis’, ‘Boxing’, ‘Volleyball’, ‘Darts’ and ‘Bowling’ were selected appropriately for TOAT according gto 5 most important limited ADL of each patient that determined with COPM. The games were set as client-centered for 45-60 minutes by the physiotherapist. All the participants completed 8 weeks (3 times in a week) of client-centered TOAT with Xbox 360 Kinect™ games.

Results: The mean age and duration of disease was 12,26 ± 3,09 (age range 8-18), 6,78 ± 4,16 years, respectively. 20 of patients had bilateral involvement of upper extremity. Wilcoxon test showed significant statistically differences pre and post-treatment, in almost all the values, except some scores of subtasks of JHFT (p < 0.001). All muscles strength of upper extremities were statistically significant increased (p < 0.001). Table 3 shows the scores of functional ability, fatigue, grip and pinch strength and activity performance outcomes pre and post-treatment.

Conclusion: Our Kinect Xbox 360 protocol that inclued client-centered TOAT has showed improvements on upper extremity functions and activity performance in patients with JIA. We think that TOAT with VBG improves the activity performance and physical functions via being stimulative and interactive in order to provide feedback and to increase interest and motivation. Xbox Kinect virtual gaming system is more fun and provides motivation, and may be a preferable method of treatment for patients with JIA but further studies are needed to compare with the potential benefits of VBG and conventional therapy in patients with JIA.

P390 The truth, the whole truth and nothing but the truth: methotrexate and compliance; the JIA patient perspective

Introduction: Methotrexate is the first-choice disease-modifying drug (DMARD) for the treatment of JIA. It is accepted as an effective drug that induces remission in more than 70% of patients. Serious adverse effects are infrequent and usually transient due to rigid monitoring guidelines. However the impact on the quality of a child’s and their family lives has yet to be adequately researched.

Objectives: The aim of this research was to investigate the JIA patient’s perspective and tolerance and compliance of oral or parental Methotrexate in accordance with BSPAR guidelines.

Methods: Children between 10-17 years of age with a diagnosis of JIA (all sub-types included) attending the Paediatric Rheumatology Day Ward were asked to complete an adapted MISS (Methotrexate Intolerance Severity Score) questionnaire during their routine medicines reconciliation and compliance interview, carried out by the paediatric rheumatology pharmacist. A total of 15 questionnaires were completed.

Arthritis Care, host activity weekends for children between 10 – 17 years of age with a diagnosis of JIA, during one such weekend they devoted a group session to discussing and completing the adapted MISS questionnaire. To date a total of 15 questionnaires have been completed in the two different settings and with two interviewees of differing provenance.

Results: Results

The children were asked “choose one word to describe how you feel about taking Methotrexate”.

Children attending Rheumatology Day Ward examples – Fine, Ok, Necessary, Annoying.

Children at the Activity Weekend examples – Evil, Depressed, Stressed, Sore, Terrible, Hate.

Conclusion: The MISS questionnaire is a well -designed validated tool widely used by Paediatric Rheumatology teams to assess Methotrexate tolerance in JIA patients. Anticipatory nausea and behavioural effects of Methotrexate are not clinically evident during physical assessment but may be detected by the MISS questionnaire. However this research poses the question how much value can we place upon the results we receive if they are so profoundly affected by the environment in which they are completed and the person who is requesting the information.

The narrow score range and low average MISS score obtained when completed with the rheumatology pharmacist creates the impression that Methotrexate is a well-tolerated drug which young patients find at worst “annoying”. Is it safe to dismiss this as the Hawthorne effect? (or should we say young patients simply trying to please us?).

Yet the dramatically higher average score and broad score range obtained at the Activity weekend indicate that Methotrexate has a significant detrimental effect on young patients creating a greatly anticipated stressful event every week.

Arthritis Care, activity weekends create an environment where young patients are free to express themselves in their own language and allow their anger and emotions to be expressed away from reproachful and anxious parents.

These findings challenge the validity of this questionnaire if it is so dependent on the environment and the questioner. Our preliminary finding demonstrate the need for further research in this field and highlight the already underestimated degree of morbidity and non-compliance associated with MTX in children with rheumatic diseases.

Introduction: Fatigue is present in 60-75% of patients with JIA. Fatigue is multidimensional, meaning that it can be physical or mental in its manifestation and cause. The causes and consequences of fatigue are not well known.

Objectives: To assess the presence and severity of fatigue in patients with JIA, including factors presumed associated with fatigue (e.g., disease activity, disability, pain, physical activity, exercise capacity, and self-efficacy), and whether fatigue is related to participation in physical education classes, school attendance, and sports frequency.

Methods: Eighty patients with JIA (age 8-13) were included. Primary outcome measurements were fatigue (multi dimensional Pediatric-Quality-of-Life-Inventory (PedsQl)-Fatigue-scale) and energy level (uni dimensional VAS scale (0-10; 0 meaning respectively lowest an highest energy)). Predictors of fatigue were disease activity (PGAS (0-10 cm)), disability(CHAQ), physical activity (accelerometer), exercise capacity (Bruce test) and self-efficacy (Childhood Arthritis Self-Efficacy Scale). Consequences of fatigue were school attendance and participation to physical education class and sports using a questionnaire.

Results: Median age was 9.8 years [8.7; 11.0], disease duration was 2.95 years [1.22; 6.19], disease activity was .03 [.00;.90] and 60 patients were on medication. Sixty percent of patients with JIA suffer from daily low-energy levels; 27% suffer from very low-energy levels more than half the week. Fatigue measured with the PEDsQL was higher compared to the norm-population (77.5 compared to 80.5). High fatigue was correlated with low energy levels (P < .01). Patients who reported higher levels of fatigue showed higher disability (P < .01), higher pain (p < .01), lower exercise capacity p = .05), lower physical activity (<.01), and lower self-efficacy scores (P < .01). Disability (p = .01) and low self-efficacy (p = .04) were main predictors of fatigue in a multivariate model. Self-efficacy was a predictor of fatigue but did not act as moderator. Low energy levels were correlated with high disability (p < .01), pain (p = .01), a lower PAL (p < .01), and being on medication (p = .03). Low energy levels were best predicted by disability (p < .01)and low physical activity (p < .01) in a multidimensional model. Fatigue was a predictor for sports frequency (p = .01) but not for school attendance (p = .08).

Conclusion: Fatigue is present in more than half of the patients with JIA. Uni- and multidimensional measurements can be used to determine the level of fatigue. However, related factors were different for both measurements as single correlations as well as in a prediction model, indicating that they are not interchangeable. Interventions aimed at reducing perceived disability, stimulating physical activity, and enhancing self-efficacy might reduce fatigue and thereby enhance participation.

Introduction: Regardless where nurses work they meet both adults and children who are scared of needle stick. Both the empirical and the literature reveals that the meeting with the children who are afraid of needle stick can be challenging and difficult to manage. According to competence description to pediatric nurses work to ensure that blood tests, examinations and treatments are tailored to the individual child. When meeting with children who are afraid of needle stick and meeting their families, it is important that the nurse takes into account several factors: the child’s age, developmental stage, previous experience and the situation the child is in. The parents’ past experiences and feelings about needle stick can affect how the child reacts to different procedures.

Objectives: To describe nurses’ experiences of meeting children scared of needle stick and meeting their families.

Methods: The study was qualitative and the collected material was analyzed using qualitative content analysis. Five nurses who worked in child care 3-42 years participated in the study.

Results: The results were reported as three categories and eleven subcategories. The categories were: Challenging encounters with children who are afraid of needle stick, Cooperation and Child different reactions. The meeting was affected by various things such as the nurse’s own experience of meeting children who are afraid of needle stick, the circumstances and the nurse’s ability to build trust and confidence. A working relationship with colleagues, children and parents was crucial so the situation would be as good as possible.

Conclusion: Fear of needle stick is a common phenomenon, especially in pediatrics. Sharing experiences and gaining knowledge on this subject make it easier for nurses who feel insecure about meeting children who are afraid of needle stick and their families. We also hope that this work will lead to discussions on this topic in the working groups who in their daily work meet children who are afraid of needle stick.

Introduction: -

Objectives: To assess the outcome of the first transition clinic from pediatric to adult rheumatology in İstanbul, Turkey

Methods: A transition outpatient clinic has been started in 2014 in Cerrahpaşa Medical Faculty with the contribution of 2 adult and 4 pediatric rheumatologists who get together once every 2 to 3 months. Patients who have been followed in the pediatric rheumatology clinic were asked to attend the transition OPC after the age of 18. These patients are seen by all the attending physicians initially in the pediatric clinic. A standardized form is filled for all which includes information on diseases history, last physical and laboratory examinations, and treatment. The next appointment is given for the adult rheumatology clinic where they are seen by one of the adult rheumatologist who have attended the first visit. All patients seen in the transition clinic during this 2 year period were contacted to assess the follow-up and outcome.

Results: Since 2014, 82 patients (52 F, 30 M) were seen in the transition OPC. The mean age was 21 years (18-24). The diagnoses of the patients were FMF in 44, JIA in 28, BD in 3, SLE in 2, vasculitis 2 and others 3. Fifty six patients were regularly attending the adult rheumatology clinic (68%), whereas 3 were being followed in another center, 9 never attended to a visit in the adult clinic and 14 were lost to follow up. The attendance rate was somewhat higher in girls compared to boys (71% vs 60%). Their main complaints were the crowdness of the adult clinics (8 patients) and insufficient attention (7 patients).

Conclusion: These are the preliminary results of the first transition clinic from pediaitric to adult rheumatology from Turkey. Compared to well established clinics from other countries like Canada, the attendance rate and the age at transition are comparable. In order to increase the attendance and the overall satisfaction of the patients the programme needs to be improved.

Introduction: Patients attending the UK’s only ‘Centre of Excellence for Childhood Lupus’ at Alder Hey Children’s Hospital, Liverpool, routinely attend clinic appointments every three months. During these appointments there is pressure for clinicians to review complex medical presentations and treatment in a timely manner. As a service we recognise the importance of holistic, multi-disciplinary care and the need to consider the priorities of patients and their families in relation to the illness and its management.

The challenges faced by patients in asking questions and asserting influence over a medial consultation are widely acknowledged and so a ‘screening tool’ was developed to facilitate this process.

Objectives: To develop a screening tool to facilitate conversations with young people with lupus and their families in order to identify areas of concern that they would like to discuss within or outside of a given clinic appointment.

Methods: Immediately prior to each clinic appointment, patients with juvenile-onset systemic lupus erythematosus (‘lupus’) and the parent or guardian accompanying them were asked to complete a bespoke screening questionnaire.

The tool was developed through detailed consultation with patients, parents and multi-disciplinary team members (nursing, occupational therapy, physiotherapy and psychology). Several versions were developed to enable the tool to be utilised by children of different ages as well as their parents. Parents of all children were encouraged to identify issues that concerned them about their child but also areas in which they felt they were struggling themselves regarding their child’s condition.

The completed tools were brought into the consultation for consideration by the attending clinicians and team. Where appropriate, the screening questionnaires influenced the topics of conversation within the appointment, otherwise, plans were made to contact the multi-disciplinary team separately.

The completed questionnaires formed part of the patients’ case notes. Data were also collated and used to inform wider service development within the lupus service.

Results: Completed screening tools were reviewed over a 10-month period. 36 were completed (19 young people, 17 parents).

Amongst the young people, the most frequently reported concerns were: fatigue (81%), appearance (58%), pain (53%) and exercise (53%). Parents were most concerned for their children regarding: fatigue (65%), pain (65%), emotions (59%), sleep (59%) and support from school or college (53%). In terms of areas in which parents were concerned about themselves, most frequently reported were: concerns regarding the future (82%), feeling upset regarding their child’s condition (59%), supporting their child (59%) and having adequate support from others (59%).

Conclusion: The questionnaires have received positive feedback from patients, parents and staff in terms of their ease of completion and their utility in terms of highlighting issues for further discussion either within clinic or otherwise. They have also helped especially to normalise the role of psychological well-being in the management of lupus.

The data have been used to influence service development including:

  • Development of a ‘health passport’ document to facilitate communication between family, hospital and school

  • Development of a workshop for patients with lupus and their families focussing on fatigue management

  • Development of a future workshop for patients and their families focussing on transition, the future and becoming a young adult with lupus.

Presenting author: Malin Höglund

Introduction: When a child is diagnosed with juvenile idiopathic arthritis (JIA) a lot of questions evolve among family members and the social surrounding. The initial information provided by the doctor may be overwhelming and it may be hard to take in all the details. Many seek additional information from literature or from the internet but feel overwhelmed by all the different information available.

Objectives: To provide parents and children with correct information included in an information bag and to evaluate the response on this initiative.

Methods: “On the journey diagnosed with JIA” is a information bag created in collaboration between the pediatric rheumatology unit at Astrid Lindgren Children’s Hospital, the Swedish Rheumatism Association, Young Rheumatic Patients, and AbbVie Sweden. The information bag contains informative brochures, lists of adequate web sites with balanced information, and information from parent and patients associations. In addition, a calendar is provided to encourage self-management of the disease. All information is carefully checked by the clinic and based on medically correct information. The bag is a compliment to the information that the family receives at the clinic; a way for the patient and family to continue the journey at their own pace back home. The pilot project consisted of 20 bags that were handed out at the pediatric rheumatology clinic at Astrid Lindgren Children’s Hospital to children newly diagnosed with JIA. The children were between 2-17 years old. After a month an assistant nurse at the clinic contacted the family by mail or by phone to evaluate how the bag had been used. The families were asked whether the information added value and if they found answers to any questions that arose after the doctor’s visit.

Results: All of the 20 families were positive to the bag and its content. They found that the information helped them to explain about JIA to people around them, in school or preschool, or on activities after schools. The content of the bag had increased understanding and knowledge of what the disease means for the child in everyday life. The material had also helped the parents to get a good basic information so that they then had a better perspective on all the information online and in social media.

Conclusion: The information bag has been an appreciated complement to the information given at the hospital and will now be implemented as a tool provided to children diagnosed with JIA at Astrid Lindgren Children’s Hospital.

Introduction: Cryopyrin-associated periodic syndromes (CAPS) and systemic juvenile idiopathic arthritis (sJIA) formally belong to the same group of autoinflammatory diseases (AID) and have a number of clinical similarities, and approaches to therapy. At the same time CAPS (cryopyrin-associated periodic syndromes) refer to AID group, associated with NLRP3 gene mutation with multiorgan damage and involvement of the central nervous system (CNS) that can result in the development of cognitive functions and determine certain psychological peculiarities.

Objectives: to carry out a fundamental psychological testing aimed at identifying peculiarities of the emotional sphere and cognitive deficits in patients with CAPS and systemic juvenile idiopathic arthritis (sJIA).

Methods: A detailed psychological examination was performed under a single diagnostic plan: 12 patients consecutively admitted to the clinic: 6 patients with CAPS (4 - MWS, 2 - CINCA-NOMID), aged from 9 to 17 years, 4 males, 2 females; average disease duration of 9 years and 6 patients with sJIA aged from 7 to 16 years, 4 males, 2 females; average disease duration of 7 years.

Methodology: clinical interview, 8-Luscher color test, Spielberger - Khanin test to identify the level of anxiety, CMAS, methods of pathodiagnostic survey.

Results: CAPS patients showed a reduction of attention functions in a part of concentration and distribution (by 66.7%), insufficient attention efficacy (increase in the time consumed in vigorous activities) in 83.3%, the low-speed entry (50%), reduced level of performance efficiency in 83.3%. Irregularities in the process of memorization, short-term memory (16%) and storage of data (long-term memory, LTM) were observed in a half. The concreteness of ideation which did not meet the age norm and reduced level of factuality were observed (50%).

An increased level of personal anxiety (66.7%), dissatisfaction with their appearance (50%), difficulty in communicating with agemates (50%), reduced level of social adaptation were observed in the emotional sphere (7%). Patients with sJIA showed the reduction of focus functions - in a part of concentration (50%), the distribution of attention (16.7%), insufficient attention efficacy (33.3%), and low speed entry (16.7%). Abnormalities in the short-term memory link were observed in 33.3%, long-term – in 16.7%. The thinking processes did not show reducing level of factuality in 33.3% and specificity of ideation inconsistent with age norm. In the emotional sphere there were revealed an increased level of personal anxiety (50%), difficulty in communicating with agemates (83.3%), dissatisfaction with appearance and reduced level of social adaptation - in a half.

Conclusion: Differences in the psychological status of patients with CAPS and sJIA were revealed. CAPS patients showed the most dramatic abnormalities in the cognitive functioning - in all functions of attention, memory and thinking, which may be indicative of the major organ damage. Disturbances in the emotional sphere are dominated in patients with sJIA (difficulty in communicating with agemates and low social adaptation). Dissatisfaction with their own appearance is equally characteristic of both groups. Clinical and psychological status of patients with CAPS and sJIA requires further study at a greater volume of material to identify sustainable patterns of regularities, assess the impact of targeted therapies and develop psychocorrective programs for cognitive and emotional disorders.

Introduction: A metaphor is considered the strongest device for an individual to comprehend and explain a hypothetical or an abstract, complex fact in a high level. Metaphors shape our perceptions, beliefs, attitudes and thoughts and they may influence the actions we take in the real world. Metaphors are among the most powerful cognitive tools to understand children with chronic disease. Juvenile idiopathic arthritis (JIA) affects social, emotional, and cognitive development of children, because it is a chronic disease in childhood. Understanding the perceptions about their disease helps to accomplish cognitive barriers of the rehabilitation in children. However, in the literature, no study has been found about perceptions about their disease in children with arthritis.

Objectives: The aim of the study was to understand the perceptions of patients with JIA about having a rheumatic disease and doing exercise via metaphors.

Methods: The population of the study included 20 (16 girls and 4 boys) patients with JIA. Each patient with JIA was asked to complete the blanks in the sentences, “Having a rheumatic disease is like a/an.....................because..................” and “Doing exercise is like a/an.....................because..................” The data were analysed using qualitative (content analysis) method.

Results: The mean age of the patients was 11.35 ± 2.20 (age range 8-18). According to the findings of the study, patients with JIA identified 24 metaphors (15 metaphors for “having a rheumatic disease”, 9 metaphors for “doing exercise”) in total. The metaphors for “having a rheumatic disease” developed by patients with JIA were analysed and interpreted at two categories: animals and objects. While the animal metaphors indicated three characteristics as “slow-moving”, “coping difficult” and “frightening” for “having a rheumatic disease”. The object metaphors indicated five characteristics as “Chaotic”,“ Stiffness”, “Formidable”, “Puffy” and “Uncertainty” for it. The metaphors for “doing exercise” indicated three characteristics as “Beneficial for Health”, “Tedious” and “Hard”.

Conclusion: As a result, the metaphors can be used as a strong research tool in understanding, revealing and explaining the cognitive images of patients with JIA about their disease and doing exercise. This study showed that patients with JIA prefered different metaphors for explaining their perceptions of disease and exercise but the reasons were similar. According to their metaphors, “Having a rheumatic disease” is similar to solving a difficult problem, “Doing exercise” is necessary for getting better but it requires the responsibility.

Introduction: Juvenile idiopathic arthritis (JIA) is characterized by joint pain, swelling and a limitation of movement caused by inflammation. Subsequent joint damage can lead to disability and activity restriction. In the literature, some evidence reports that patients with JIA are physically less active when compared with healthy children. Active video gaming such as Xbox 360 Kinect is a promising physical activity alternative given that children are encouraged to move whilst engaging in an activity they enjoy.

Objectives: The purpose of this case report is to describe effects of Kinect based dance therapy (KBDT) on lower extremity functions of a patient with oligo articular JIA.

Methods: The patient was 18-year-old girl with oligo articular JIA. She had left hip arthritis. So, she had dissatisfaction about her appearance during the walking because of limitation of hip range of motion and increased anterior pelvic tilt. Also, she complained of pain and fatigue at rest and during the walking. Pain during rest and activity was assessed using a 0-to-10 Numeric Rating Scale (NRS). Fatigue severity was also measured by NRS with higher scores indicating high fatigue, Active and passive Range of motion (ROM) of lower extremity was measured using a standard goniometer. Muscular strength was estimated at maximal isometric force for the muscles of the lower extremities by using a portable digital handheld dynamometer. Static balance was measured by using the Functional Reach Test (FRT) and Lateral Reach Test (LRT). Functional ability was assessed by Childhood Health Assessment Questionnaire (CHAQ). Functional capacity was assessed by 6 minutes walking test (6MWT). The total distance was recorded during walking for 6 minutes. Our KBDT program was composed of “Dance Central 2”. Dance Central 2 is a rhythm game developed exclusively for the Xbox 360 Kinect. During the game, players perform given dance moves similar to a mirror, which are tracked by the Kinect. The more accurately the player performs the move, the more points he/she scores. Higher difficulties increase move complexity. 4-5 different dances that included weight bearing and balance actions for lower extremity were selected for our KBDT program. She completed 8 weeks (3 times in a week) of her specific KBDT program.

Results: Pain scores of NRS-rest and NRS-activity and NRS-fatigue were 5 point before the treatment. After treatment NRS-activity was 1 point, both NRS-rest and NRS-fatigue were 0 point, Active ROM of Hip flexion was 70, hip extension 20, abduction 20, internal rotation 30, and external rotation was 30 degrees before the treatment. After the treatment, Active ROM hip flexion was 90, hip extension 35, abduction 45, internal rotation 45, and external rotation was 40 degrees. FRT scores of pre and post-treatment were 36 and 45 cm respectively. LRT scores of pre and post-treatment were 22 and 30.5 cm respectively. Pre and post-treatment scores of 6MWT were 406 and 522 meters, respectively. CHAQ total, CHAQ-walking, CHAQ- activities scores were 1.12, 2 and 2 before the treatment respectively. All CHAQ scores dropped to 0 after the treatment. Also, all muscle strength scores of both lower extremities were improved after the treatment.

Conclusion: In this study, we found clinically significant improvements of lower extremity functions, functional capacity, pain and fatigue for a patient with oligo articular JIA. This indicates that repeated actions with visual and auditory feedback provided by Kinect-based virtual reality may increase patient focus and motivation and thereby improving the quality of movements. This case report describes a novel approach to rehabilitation of patients with JIA but further investigation into the effectiveness of KBDT for children with JIA is warranted.

Introduction: Adolescent departments in France are usually devoted to the care of mental health disorders. Yet, there is a huge need for chronic organ-diseases care, focused on adolescents specifically. Adolescence is often a difficult period but chronic organ-disease as JIA, may amplify the troubles, thus requiring a particular effort.

Objectives: Improve the daily life of adolescents and young adults with JIA with practical actions.

Methods: We chose to start with the improvement of patient education in adolescents and young adults having juvenile idiopathic arthritis in France. We created the first patient association “AJIados” involved in adolescent/ young adults in France.

Results: AJIados supports different actions : (i) collective meetings between the young people, between their parents/families, between them and caregivers. We organize 4 times a year, collective assemblies on various themes, generally chosen by the patients; all together, we create small documents to help solving practical problems (school, physiotherapy, living with a uveitis…) and distribute them across our country as well as in the Maghreb. We also send to interested people our newsletter every 3 months. Our efforts have had a great success with always more adolescents and families; (ii) we organized nice encounters with key figures in french sport and music, who are vectors of hope and will go on this way; (iii) we created a web-site ( to help patients in their daily life: there are 5 modules (a forum, a tool box, news on research as well as surveys, an agenda with referral caregivers that is built and improved by the patients themselves and a growing part devoted to patient education).

Conclusion: Presently, the success is « au rendez-vous » with the adolescents and young adults, justifying to pursue all our efforts.

Presenting author: Sirirat Charuvanij

Introduction: Juvenile idiopathic arthritis (JIA) is a chronic disease resulting in pain and disability. There has been no study focusing on health-related quality of life (HRQOL) among Thai children with JIA.

Objectives: To describe HRQOL and determine factors influencing the HRQOL of Thai JIA patients.

Methods: A cross-sectional descriptive study was conducted in JIA patients and their parents followed up at a pediatric rheumatology clinic, Siriraj Hospital, Bangkok, Thailand. HRQOL was measured by using the Pediatrics Quality of Life (PedsQL) 4.0 generic core scale, Thai version, during January 2015-December 2015. Suboptimal HRQOL is defined as a PedsQL total mean score of < 78.6.1

Results: Sixty-five patients and their parents were included. Thirty-three patients were female (50.8%). Mean age of patients was 9.6 ± 3.9 years and the median of duration of the disease was 1.1 (0.0-9.43) years. Systemic JIA was the most common JIA subtype (40%). The median of Juvenile Arthritis Disease Activity Score-71 (JADAS-71) was 7 (0-27.2). Forty-nine (75.4%) patients were having active disease. The median of total PedsQL score reported by patients was 80.6 (36.9, 100); physical functioning score 78.1 (34.4, 100), emotional functioning score 85 (35, 100), social functioning score 90 (30, 100), school functioning score 80 (25, 100). There were 25 (45.4%) patients classified as having suboptimal HRQOL. The median of total PedsQL scores reported by parents was 71.7 (33.3, 100); physical functioning 75.0 (0, 100), emotional functioning 80 (40, 100), social functioning 85 (25, 100) and school functioning 65 (25, 100). Suboptimal HRQOL was identified in 39 (60%) patients based on parent reports. There was positive correlation between total PedsQL scores reported by children and their parents (rs = 0.662). There were no statistically significant factors associated with suboptimal HRQOL reported by children. Non- oligoarthritis; OR 3.8 (95%CI: 1.0, 14.6), joint pain; OR 4.1 (95%CI: 1.4, 11.5), limping; OR 4.7 (95%CI: 1.2, 18.7), wrist arthritis; OR 8.6 (95%CI: 1.0, 72.1), elevated erythrocyte sedimentation rate: OR 2.8 (95%CI: 1.0, 7.9), elevated C- reactive protein: OR 3.2 (95%CI: 1.1, 9.2), active disease; OR 4.9 (95%CI: 1.2, 16.8), high disease activity (JADAS-71 ≥ 10.5); OR 12.6 (95%CI: 2.6, 60.9) and oral steroid use; OR 3.2 (95%CI: 1.0, 10.3) were associated with suboptimal HRQOL reported by parents. However, only high disease activity influenced on the suboptimal HRQOL by multiple logistic regression analysis; adjusted OR 20.2 (95%CI: 1.4, 291.7).

Conclusion: Almost half of Thai JIA patients had suboptimal HRQOL. The physical functioning score was the lowest aspect. The factor associated with suboptimal HRQOL reported by parents was high disease activity.

Institute of Rheumatology, Tokyo Women’s Medical University, Tokyo, Japan
Presenting author: Takako Miyamae

Introduction: The goal of planned adolescent healthcare transition procedures is to optimize the functioning and well-being of all young people, including those with special healthcare needs. In this regard, the transitioning of young people with childhood-onset rheumatic diseases to adult healthcare is increasingly important, as many of these patients might continue to have active disease or considerable sequelae well into their adult lives.

Objectives: Attitude surveys of pediatric and non-pediatric rheumatologists about transition procedures were performed.

Methods: Overall, 28 operation commissioners of the Pediatric Rheumatology Association of Japan and 37 non-pediatric rheumatologists belonging to the Institute of Rheumatology, Tokyo Women’s Medical University participated in the surveys. Experiences of adult patients with childhood-onset rheumatic diseases, ideal medical care for adults, and factors contributing to challenges associated with the transition to adult care were examined.

Results: In total, 19% of pediatric rheumatologists still see their patients as adults, whereas 62% of non-pediatric rheumatologist have experiences with childhood-onset patients. Transition to non-pediatric medical care was supported by 81% and 95% of pediatric and non-pediatric rheumatologists, respectively. A preparatory step of visiting both a pediatrician and a non-pediatrician is recommended by some physicians. Two major factors, incomplete facilitation of personal independence to make the transition to adult care and the sharing of pediatric rheumatology knowledge and skills with non-pediatric rheumatologists, particularly with respect to autoinflammatory disorders, were identified as contributing to challenges associated with successful transition. Overall, 33 of 37 (89%) non-pediatric rheumatologists required education about childhood-onset rheumatic diseases.

Conclusion: Key elements for effective transitions include the development of education programs to help pediatric patients manage their illness independently and to share pediatric rheumatology knowledge within the non-pediatric rheumatology community.

Introduction: Inherited inflammatory syndromes related to the transmembrane protein 173 (TMEM173) gene gain-of-function mutation were described so far by the triad early-onset systemic inflammation, marked cutaneous vasculopathy and pulmonary fibrosis, with variable clinical expression even in familial cases (1,2). Recently, we have reported that TMEM173 mutations can be associated to inaugural lung interstitial disease (ILD) with late-onset systemic symptoms (3).

Objectives: To investigate pathological features of the lung disease of STING-associated ILD.

Methods: Clinical and biological data, chest HRCT and lung biopsies were collected retrospectively in 2 children and one adult with TMEM173 mutation. Paraffine-embedded tissues were stained for IFNa (clone MMHA-2), CXCL10, IFNAR1 and MxA and compared to healthy controls and non genetic ILD (systemic sclerosis).

Results: Initial presentation was related to symptoms suggestive of pulmonary fibrosis for all patients. Few systemic features appeared later on life and skin damage was mild, delaying the evocation of a systemic disease. Classical causes of familial interstitial lung disease were all excluded genetically and all three patients had an already known genetic variant of TMEM173. Cystic lesions on HRCT predominated in upper lobes with relative preservation of lower lobes. Immunohistological analysis showed fibrosis with destruction of alveolar architecture associated with follicular lymphoid infiltrates (neolymphogenesis) containing a majority of B cells CD20+. The overall architecture differs from other common ILD. Intra-alveolar infiltrate was made of macrophages and cholesterol crystal clefts was noticed for the 3 patients. Interestingly, there was no evidence for vasculopathy or microangiopathy. By contrast, a huge induction of IFN-related protein in the lung section of patients was observed as compared with controls. A strong interferon signature was found in all three cases.

Conclusion: The diagnosis of STING-related lung fibrosis should be considered as a differential diagnosis of ILD in children even with no or mild systemic features. The pathological study may represent a useful procedure to support the diagnosis.

Written informed consent were obtained from all the participants of the study.

Introduction: Deficiency of adenosine deaminase 2 (DADA2) is an autosomal recessive autoinflammatory disease resulting from a loss-of-function mutation in CERC1 gene encoding for ADA2 protein. The patients present with systemic inflammation and vasculopathy.

Objectives: We aimed to present the characteristics of the pediatric DADA2 cases.

Methods: The clinical and laboratory features of thirteen pediatric patients (8 M, 5 F), who were diagnosed with DADA2 at Hacettepe University Pediatric Rheumatology Department between 2014-2016, have been summarized. Mutations in CECR1 were detected by Sanger sequencing.

Results: Eleven patients were homozygous for G47R mutation in CECR1 gene, one was compound heterozygous for G47R and G47V while one patient was heterozygous for G47R. Seven of these patients had been followed up in our clinic with the diagnosis of polyarteritis nodosa (PAN). There was consanguinity in four cases, and two patients were siblings. The median (min-max) age at onset of the symptoms and diagnosis was 5.5 (1.4-19) and 120 (36-211) months, respectively. All patients suffered from recurrent episodes of fever with elevated acute phase reactants. Skin manifestations were as follows: livedo reticularis (n = 13), erythema nodosum (n = 4), and necrotic ulcers (n = 2). Neurological and musculoskeletal involvement was in the form of myalgia (n = 5), arthralgia (n = 10), arthritis (n = 5), stroke (n = 8), strabismus (n = 3), peripheral neuropathy (n = 6), and spinal cord atrophy (n = 1). One patient had been diagnosed with core myopathy through muscle biopsy which was thought as a co-incidental finding. Optic neuritis was detected in one patient. There was Raynaud’s phenomenon in two patients. Four patients had aneurysms in different middle-sized arteries (hepatic artery, renal artery, and superior mesenteric artery). One patient had intestinal perforation and ileostomy at the age of eight. As renal involvement, one patient had focal segmental glomerulosclerosis (collapsing variant), one mesangial proliferative glomerulonephritis (renal subcapsular hematoma after renal biopsy), and one had renal amyloidosis. There was testicular torsion in one patient. Three patients had positive antinuclear antibody while there was low levels of immunoglobulin M in two patients. Two adult patients died soon after diagnosis of DADA2. One patient was asymptomatic on only colchicine for almost 10 years. One responded to mycophenolate mofetil treatment. Rest of the patients responded well to anti- tumor necrosis factor therapy (etanercept).

Conclusion: ADA2 protein is a growth factor for endothelial cells and leukocytes and is important for stabilization of endothelial cells. For this reason, it causes autoinflammatory symptoms as well as vasculitis symptoms similar to PAN. ADA2 deficiency is a recently defined disease and the data about its phenotype increases with the introduction of new cases with different symptoms. This is the first description of spinal cord atrophy, core myopathy, and mesangial proliferative glomerulonephritis in DADA2 patients. Similar to the patients in the literature, most of our patients responded to etanercept therapy. Our cases suggest the diverse phenotype of DADA2.

Introduction: Recently, we identified a S242R mutation in pyrin in 12 patients from a three-generation Belgian family suffering from childhood-onset recurrent episodes of severe neutrophilic dermatosis, arthralgias/myalgias and systemic inflammation. The mutation results in the loss of a 14-3-3 binding motif at phosphorylated S242, resulting in continuous pyrin-inflammasome activation and excessive IL-1β production. Because of the genetic causation by pyrin mutation and the characteristic features of systemic inflammation and dermatosis, we termed this disease pyrin-associated autoinflammation with neutrophilic dermatosis (PAAND). We found additional patients in Lebanon, France and UK, where one patient received treatment with the IL-1 receptor antagonist monoclonal antibody (mAb) anakinra leading to a resolution of symptoms and normalisation of inflammatory markers.

Objectives: To assess the efficacy of the IL-1 receptor antagonist mAb anakinra (Sobi) in controlling the clinical and biochemical consequences of constitutive activation of the pyrin inflammasome in patients with PAAND.

Methods: Three Belgian patients with the S242R pyrin mutation are treated with daily subcutaneous injections of Anakinra 100 mg for 12 weeks. Previous therapy with TNF-antagonists was stopped and concomitant immunosuppressive treatment was limited to low-dose corticosteroids. Clinical cutaneous, articular/muscular manifestations and inflammatory markers are assessed at baseline, and after 2, 4, 8 and 12 weeks. In addition presence of cytokines and activated caspase1 as well as inflammasome activation in vitro are assessed at baseline, 4 and 12 weeks.

Results: At baseline, all three patients manifested neutrophilic dermatosis in the form of severe cystic acne and sterile abscesses, diffuse myalgias and arthralgias, fatigue and night sweats, and abdominal pain associated with diarrhea. Inflammatory markers were increased and mild anemia was present.

At the time of writing, i.e. two weeks after the start of anakinra treatment inflammatory markers were normalized in all three patients. All patients showed manifest improvement of the cutaneous manifestations, reduction of the gastro-intestinal pain with normalization of the stools and a reduction of the musculoskeletal pain. Night sweats had disappeared, but fatigue was still present.

Conclusion: PAAND is a new autosomal dominant autoinflammatory disease caused by a specific S242R mutation in MEFV leading to constitutive activation of the pyrin-inflammasome. The clinical phenotype is dominated by severe neutrophilic dermatosis and systemic inflammation. Treatment with Anakinra resulted in suppression of clinical manifestations and control of inflammatory markers, endorsing the key pathogenic role of IL-1 in PAAND.

Introduction: We will report a girl with immunoglobulin G4-related disease (IgG4-RD), a newly recognized disorder that share particular pathologic (infiltration of IgG4-rich plasma cells or fibrosis), serologic (elevated serum IgG4), and clinical features (multifocal phymatoid or hypertrophic lesions).

Objectives: Child patient with IgG4-RD is very rare and its pathophysiology is thought to be different from adult cases1). We will report our patient whom treated with mycophenolate mofetil (MMF) for the purpose.

Methods: Retrospective analysis based on charts.

This report was approved by Ethics Committee of Osaka Medical and Pharmaceutical University.

Results: She complained exophthalmos when she was twelve years old. MRI was performed at former hospital that revealed tumefaction of lacrimal gland and salivary gland. Serum IgG4 concentration was significantly high (1090mg/dl) and biopsy specimen from salivary gland showed infiltration of IgG4-positive plasma cells (>50%). She was diagnosed as IgG4-RD and oral prednisolone (1mg/kg) was administered. Because of steroid-induced glaucoma, the disease control was difficult to manage and she was introduced to our hospital at age of thirteen. Laboratory data: WBC 10020/μl, PLT 31万/μl, CRP 0.01mg/dl, ESR 23mm/1h, IgG 2960mg/dl, IgA 45mg/dl, IgM 115mg/dl, IgE >5000Iu/ml, IgG4 1370mg/dl, CH50 41 U/ml, C3 90mg/dl, C4 15.6 mg/dl, AST/ALT 13/22U/L, γGTP 19U/L, BUN 15mg/dl, CRN 0.54mg/dl, autoantibodies negative, no abnormality in urine test. Abdominal CT and MRI were performed that showed IgG4-related cholangitis, cholecystitis and nephropathy. Bile duct wall was edematous and wall thickening was exhausted, so we diagnosed her status as CS-resistant. We prescribed MMF (800mg/kg) and she was responded clinically and serologically. Her disease activity has been controlled well since then. IgG4-RD is a male dominant disease and peak age is between forties and seventies in adults. Among pediatric patient of IgG4-RD, girls are double to boys and their age ranged from two to seventeen. Despite the recognition that pediatric IgG4-RD shows different characteristics, little was known about the pathogenesis, adequate therapy and prognosis yet. Though corticosteroid (CS) therapy was effective for most patients, half of them experienced relapse or recurrence with reducing CS2). CS-sparing agents that include azathioprine, rituximab, cyclophosphamide and MMF are required for them. But it is not clear when it should be started and which agent would be adequate as a maintenance therapy.

Conclusion: Our patient with pediatric IgG4-RD who was resistant to CS monotherapy responded to MMF. Further study about children with this rare disorder and confirming the response to maintenance therapy is necessary in worldwide.

Introduction: Autoimmune polyendocrine syndrome (APS) type 1, also known as autoimmune polyendocrinopathy-candidiasis-ectodermal dystrophy (APECED), is a rare autosomal recessive disease. The classic features are chronic mucocutaneous candidiasis, hypoparathyroidism and adrenocortical failure. Several non-classic presentations of the disease have been described over the last few years.

Objectives: Authors present a case of 14-year old girl with prolonged seizures as a new serious non-classic presentation of APS type 1.

Methods: case report

Results: Patient was diagnosed with a mucocutaneous candidiasis and hypoparathyroidism at the age of 3 years. APS 1 was diagnosed at 9 years of age shortly after diabetes mellitus type 1 had been recognized. Mutational analysis of the AIRE gene showed R257X (c.769C > T) mutation. Typical symptoms of Addison disease - weakness, fatigue and hyperpigmentation - developed at 13 years of age. At 14 years she was admitted to hospital for prolonged seizures. Hypoglycemia and hypocalcemia were excluded as a cause of the seizures. EEG showed finding non-specific for epilepsy. Examination of the CSF was performed to exclude infection (herpetic viruses, etc.). MRI angiography did not show vasculitis or other organic changes of cerebral vessels. Specific autoantibodies for autoimmune encephalitis turned out to be positive in CSF (antiGAD65 > 2000 MU/L) as well as in blood (>2000 MU/L). Immunosuppressive treatment (glucocorticoids and i.v. immunoglobulins) in combination with antiepileptics resulted in a clinical course without seizures.

Conclusion: Differential diagnosis of autoimmune damage of CNS is a new challenge for pediatric rheumatologists. Autoimmune GAD65-positive encephalitis should be considered a new component of the clinical spectrum of APS in patient with new onset neuropsychiatric symptoms.

Introduction: Considering that the ultrasound is a validated method for assessing inflammation activity in peripheral joints our aim in this pilot study was to determine whether the ultrasound/Color Doppler could be used to diagnose sacroiliitis in juvenile SpA patients.

Objectives: To determine the value of ultrasound/Color Doppler in diagnosing acute sacroiliitis in comparison with the established method which is considered a standard - the MRI. To compare data collected from our jSpA patients with previously published predisposing factors for the development of sacroiliitis.

Methods: We performed ultrasound/Color Doppler and MRI of sacroiliac joints using a standardized protocol on 112 patients observed for jSpA. All patients had low back pain and clinically suspected acute sacroiliitis. Out of 112 patients 43 were male and 69 female with average age of 13.9. Patients age at the beginning of the disease, number and sequence of joint involvement, history of rheumatic diseases in the family and results of HLA serotyping were recorded. All ultrasound and MRI examinations were performed by two MSK radiologists with an experience in imaging methods and protocols for rheumatic diseases.

Results: Active disease or acute sacroiliitis was noted using ultrasound/Color Doppler examination in 31 patients while 81 showed no signs of synovitis. MRI detected 28 patients with active disease. Only eight patients had ultrasound signs of disease activity confirmed on MRI. Based on preliminary results sensitivity of ultrasound/Color Doppler examination in detecting acute sacroiliitis in jSpA patients is 28.6% and specificity is 72.6%. Positive predictive value is 0.26 while negative predictive value is 0.75. Out of 41 patients with sacroiliitis confirmed on the MRI (both active and chronic) 27 of them had positive HLA- B27 serotyping, 9 had hip joint inflammation at the disease onset and only 5 had positive family history of rheumatic diseases.

Conclusion: MRI is a method of choice for detection of acute sacroiliitis but due to the waiting lists it can take a substantial amount of time before the examination can be performed. In order to get the diagnostic information as soon as possible ultrasound examination is often indicated. Ultrasound is an available, cheap and relatively easy method to perform and it doesn’t have the harmful effects of radiation which is especially important in the pediatric population. In sacroiliac joints imaging ultrasound has serious limitations due to the complex joint anatomy and a relatively small imaging “window” that enables us to visualize and analyze only the dorsal aspect of the joint. Evaluator has to make sure to that the Doppler signals acquired are the result of the increased vascularization within the synovia in the intraarticular space and not the result of imaging of the blood vessels in the periarticular soft tissues. Optimizing the image parameters is extremely important as well as imaging experience. As our preliminary results show using ultrasound CD as an alternative to MRI is questionable due to the low sensitivity and specificity of the method resulting from the limitations mentioned. Ultrasound is not the adequate method for demonstrating acute sacroiliitis and patients with high clinical suspicion of sacroiliitis should perform MRI in order to confirm the diagnosis.

Introduction: Juvenile spondyloarthritis (JSpA) included several subtypes of juvenile arthritis, the main of there are follows: juvenile onset of ankylosing spondylitis (JAS), enthesitis-related arthritis (ERA), juvenile psoriatic arthritis (JPsA). Biologics, TNF-inhibitor mostly, provided excellent progress in JSpA outcome for the last 15 years. Drug survival is a general marker of the treatment success as it depends of its efficiency and safety.

Objectives: To compare drug survival of biologics depending on the subtype in JSpA patients (pts) in real clinical practice of single center.

Methods: The study involved a prospective cohort of JSpA pts treated by different TNF-inhibitors in our clinic from 2004 to 2016. Analyze included drug survival with Kaplan-Meier, reasons of withdrawals and adverse event (AE) rates.

Results: 177 JSpA pts, treated with one or more biologics were analyzed. At the start of biologics pts average age was 13.19 ± 3.7 years (range 3.58-17.9); mean disease duration was 50,4 month (range 2-163). JSpA subtypes were as follows: JAS, fulfilled to modified New-York criteria - 48(26%), ERA - 106(60%) and JPsA - 23(13%), diagnosed according to ILAR (2001) criteria, 149(83%) were HLA-B27positive. 24(13,4%) had uveitis. In total, 205 treatment series, including 79 for etanercept (185 patient-year PY), 73-adalimumab (160 PY), 53-infliximab (182 PY) were evaluated. There were 62 cases of withdrawals. Reasons for withdrawals were AE in 7,32% (95%CI 4.49-11.72), inefficacy -i10.73% (95%CI 7.19-15.71), others – 11,71% (95% CI 8-16,83), basically due to organizational difficulties of biologics access in adult life. AE were developed after at mean 1.63 years (range 0.74-3,36). AE were included: etanercept – 3 cases of uveitis de novo (1.62 per 100 PY); infliximab – 6 infusion reactions (3.3 per 100 PY), 1 psoriasis de novo, 1 severe skin disorder, 1 toxic hepatitis, 2 tuberculosis; adalimumab – 2 psoriasis de novo, 1 tuberculosis. AE as a reason of Infliximab withdrawal was observed more often than under adalimumab or etanercept (18.9% vs 2.74% and 3.8% respectively, p < 0.05). Due to inefficacy Infliximab was cancelled more often than adalimumab (16.9% vs 6.85%, p < 0.05). Etanercept was rare withdrawn due to organization problem in compare to infliximab and adalimumab (6.3% vs 16.98% and 13.7%, p < 0.05). Long-term drug survival of TNF-inhibitors was 78% for ERA, 64% for JAS and 57% for JPsA. Drug survival for etanercept were 95% and 35% after 1 and 5 years, infliximab – 90% and 38%, adalimumab – 97% and 32%, respectively. The average survival rate of etanercept and adalimumab was higher in ERA vs JAS and JPsA (84% vs 68% and 67% respectively), but for infliximab it was similar in all JSpA subtypes.

Conclusion: Our experience of long-term study of TNF-inhibitors in JSpA demonstrated the best rate of drug survival for etanercept in pts with different subtype of JSpA, especially in ERA. Infliximab mostly withdrawn due to AE and inefficacy, but adalimumab cancelled more often because of organizational reasons, especially in adult life.

Introduction: Several outcome measures in trials with juvenile-onset spondyloarthritis (Jo-SpA) have been borrowed from trials in juvenile idiopathic arthritis and from adult spondyloarthritis, but a proper psychometric analysis has never been conducted in patients with Jo-SpA.

Objectives: To assess discriminatory aspects of several disease activity outcome measures and response criteria for Jo-SpA.

Methods: Data from a previously reported 12-week RCT comparing infliximab (IFX) and placebo (PBO) in patients <18 years with Jo-SpA and onset <16 years of age were analyzed. The primary endpoint of the trial was the number of active joints (both swollen and tender). Several other disease activity measures and response criteria were also tested (Table 5). Statistics to determine how well disease activity measures could discriminate between IFX and PBO included ‘standardized mean difference’ (SMD) and ‘Guyatt’s effect size. Both statistics are standardized measures to compare change from baseline per group. For categorical response criteria, the chi-square test (χ2) was used. Higher numbers indicate better discriminatory capacity.

Results: Patients were randomised to IFX (n = 12) and PBO (n = 14). Of the continuous measures, the ASDAS showed the best and very good discrimination between IFX and PBO (SMD:1.98; Guyatt: 4.28) (Table 5). The physician’s global, CRP, JADAS and JSpADA also discriminated well. The BASDAI (or its separate items), BASFI and spinal mobility measures performed worse. Of the response criteria ASAS40 (IFX 55% vs PB = 0%, χ2 10.05) and ACR Pedi 90 (IFX 67% vs PBO 7%, χ2 10.12) discriminated best between IFX and PBO. ASDAS response criteria (ASDAS-MI: IFX 63% vs PBO 0%, χ2 8.65, ASDAS-CII IFX 88% vs PBO 20%, χ2 8.10) and ACR Pedi 30-70 also performed well.

Conclusion: Of all continuous measures tested in adult axial SpA the ASDAS discriminates best between active treatment and PBO in patients with Jo-SpA. But the child specific JSpADA also performs well.

Of all response criteria tested the child-specific ACR Pedi 30 to 90, as well as the adult ASAS40 and ASDAS response criteria work well. One of these measures should be used as primary endpoint in trials with Jo-SpA.

Introduction: Therapeutic options for Enthesitis Related Arthritis (ERA) include monotherapy or combination therapy with non-steroidal anti-inflammatory drugs, disease-modifying anti-rheumatic drugs (DMARDs), and biological agents. Until today, the approach to managing ERA is guided in large part by evidence from studies in adults with SpA and other forms of JIA.

Objectives: This study aim is determined whether effectiveness of DMARDs in ERA patients.

Methods: Fiftytwo ERA patients who satisfied ILAR criteria were enrolled in the study. The patients with psoriasis, inflammatory bowel disease, reactive arthritis and undifferentiated arthritis were exculuded. Patient information was obtained from the records. Registered data included demographic features, medical history, initial and following physical examination, initial juvenile spondyloarthritis disease activity index(JSpADA), initial laboratory tests, radiographic tests, JADI -A (Juvenil Arthritis Demage Index-articulary) and JADI-E(extraarticulary) on last admission, and all of medical treatment.

Results: We evaluated response of DMARDs in 52 patients. Twenty-seven patients (52%) achieved remission with DMARDs, while 25(48%) patients were not achived remission with DMARDs. Diagnosis of age, gender, family history of AS, inflammatory back pain, shoulder, hip, small joint involvement, sacroileitis with physical examination, enthesitis, presence of uveitis, presence of HLA-B27, initial high AFR levels, initial JSpADA score, last JADI-A score did not determinated risk factor on unresponsiveness of DMARD(HR:1, p > 0.05). Although it was not statistically significant, sacroileitis determinated with MRI increased 2.84 fold on unresponsiveness of DMARD with cox-regression analysis (p > 0.05). DMARD effectiveness decreased 50% at 20th month in this group with Kaplan-Meier analysis.

Conclusion: There are no significant differencies periferic between axial involvement treated with DMARD in our study. Therefore we believe that DMARDs kept up to date.

Introduction: Fibro myalgia (FM) is characterized by widespread chronic musculoskeletal pain with fatigue, poor sleep, frequent psychological difficulties, and multiple tender points on physical examination. In adult cases, American College of Rheumatology 2010 (ACR2010) criteria was proposed as clinically useful tool, and the analyses of the underlying disease of FM based on this criteria demonstrated that some FM cases are complicated with SpA, one of which pathogenesis is enthesitis. Here, we examined ultrasound findings on entheses of juvenile FM patients.

Objectives: To identify the ultrasound (US) picture of peripheral entheses in juvenile patients with FM.

Methods: A single-center study was performed in 8 patients with definite juvenile FM according to suggestive symptom (a widespread pain resulting in school absenteeism). US assessment of the following four entheses was performed bilaterally by a senior rheumatologist: distal Achilles tendon, distal and proximal patellar tendon, and quadriceps tendon.

Results: The patients were 6 women and 2 men with a mean age of 14 ± 1 years. Total 64 entheses was examined. Inflammatory enthesitis was detected in 36 entheses (56.3%), and enthesopathy detected in 8 entheses (12.5%). All of patients had at least one lesion: inflammatory enthesitis was detected in 8 patients (100.0%), and enthesopathy detected in 6 patients (75.0%).

Conclusion: All juvenile FM cases were found to have enthesitis by US. Our result showed that a part of juvenile FM patients are probably complicated with enthesitis.

Introduction: Gene expression profiling of juvenile spondyloarthritis (jSpA) patients revealed aberrant expression of some genes, but the mechanism of this expression alterations remained unknown (1).

Objectives: To discover epigenetic modifications with effect on regulation of 4 genes (TLR4, NLRP3, CXCR4, PTPN12) differentially expressed in jSpA patients.

Methods: DNA methylation analysis was performed in promotor region of differentially expressed genes by methylated DNA Immunoprecipitation (meDIP). Based on literature search, 4 microRNAs (miR-150, miR-146a, miR-181a, miR-223) included in regulation of differentially expressed genes were selected and their expression was analyzed using RT-PCR with predeveloped Taqman microRNA assays. Both analysis were performed in 7 newly diagnosed untreated jSpA patients and 7 matched healthy children.

Results: Statistical analysis revealed no difference in methylation of promotor sites for examined genes, but PTPN12 showed trend towards higher methylation (p = 0,076), compared with control group. There was no statistical difference in expression of selected miRs between two groups.









PTPN12 (fold enrichment)























Conclusion: jSpA is a multifactorial disease in which a complex interplay occurs between the immune system and environmental factors on a predisposing genetic background. One of the most important mechanisms by which environment can influence processes inside of an organism is gene regulation via epigenetic modifications. Therefore, we investigated possible influence of DNA methylation and posttranscriptional modifications on the genes differentially expressed in jSpA patients. The results didn’t indicate any statistically significant abundance of miRs with described role in expression of examined genes, nor hypermethylation of their promotor sites, but there was a clear trend of higher methylation of PTPN12 in jSpA patients, while lack of statistical significance could be attributed to small number of study participants. This observation can easily explain decrease of PTPN12 expression in treated and untreated jSpA patients. PTPN12 expressed in dendritic cells is identified as a key regulator of dendritic cell migration as well as T cell-dependent immunity and autoimmunity (2). It is also a negative regulator of inflammation and intestinal cell migration, as well as a positive regulator of osteoclast activity, all of which are processes important for the pathophysiology of jSpA. Results of our study are in concordance with previous epigenetic studies of this gene in human breast cancer patients, which showed PTPN12 can be silenced by methylation. Interestingly, more recent study pointed to the potential of 5-Azac, a DNA hypomethylating agent, in increasing PTPN12 expression, and highlighted the therapeutic potential of this mechanism in treatment of breast cancer (6). Therefore, it is tempting to speculate the results of our study could after confirmation in larger cohorts give rise for new treatment options in jSpA patients as well.

Introduction: Enthesitis-related arthritis (ERA) is a category of Juvenile idiopathic arthritis considered to be a form of Juvenile Spondyloarthropathy (jSpA). Tumor necrosis factor (TNF)-blocking strategies have proven effective in the treatment of jSpA1-2.

Objectives: To assess effectiveness of anti-TNF treatment in a cohort of patients with ERA; to search for associations between clinical features at treatment onset and inactive disease (ID).

Methods: Retrospective review of prospectively collected data. Patients with ERA (according to ILAR criteria) continuously treated with anti-TNF agents for ≥ 3 months were included. At visit 0 (baseline) and every 3 months thereafter Information was collected on therapeutic agents used and the following disease activity measures: joint count, pain score (0-10), presence of active enthesitis (AE), sacroiliac pain (SIP) or lumbar limitation (LL), wellbeing according to the patient using a visual analogue scale (VASp, 0-10), disease activity according to the physician (VASphy, 0-10), JADAS-102, JSpADA3, and ESR. Functional capacity was also assessed through the use of CHAQ. Occurrence of ID (defined as JADAS-10 £ 1 or as per Wallace et al4) and clinical remission (CR)4 was recorded. ANOVA and Mann-Whitney U test were used for comparisons between visits, while associations were analyzed with chi square and Sperman’s rank correlation.

Results: 30 patients fulfilled inclusion criteria. Patients were followed at a specialized clinic during the period 2002-2015.They were all male, 43% HLA-B27 positive; median age at start of TNF-blocker therapy was 13 years, disease duration 3.5 years; median observation period was 18 months. Twenty-seven (90%) children showed peripheral arthritis while 22 (73%) exhibited sacroiliitis on MRI/Xrays at start of therapy. Patients received etanercept (23, 2 were later switched to adalimumab and 1 to infliximab), adalimumab (5), or infliximab (2). At baseline patients showed (medians): active joints (AJ) 4, pain 1.5, VASp 2, VASphy 2, JADAS-10 9.75, JSpADA 2.5, ESR 16.5 mm/h, and CHAQ 0.25. AE was present in 4 (13%), SIP in 7 (23%), and LL in 12 (40%) children. All patients showed JSpADA > 0 and 29 (97%) children had JADAS > 1 at entry. At 3 months JADAS-10 decreased to 5.5 (p = 0.007) and JSpADA to 1.25 (p = 0.002); 6 (21%) patients achieved ID. At 12 months patients showed AJ 0 (p = 0.01), pain 0 (p = 0.009), VASp 0 (p = 0.0005), VASphy 0.75 (p = 0.0001), JADAS-10 3 (p = 0.0001), JSpADA 1 (p = 0.0004), ESR 6 mm/h (p = 0.02), and CHAQ 0 (p = 0.12). AE was present in 0 (p = 0.08), SIP in 0 (p = 0.01), and LL in 6 (24%) (p = 0.03) patients. ID was recorded in 22 (73%) and CR in 9 (30%) children during the observation period. Achievement of ID at 12 months was associated with baseline presence of active sacroiliitis (p = 0.02).

Conclusion: In this retrospective cohort of ERA patients on TNF-blockers a significant and progressive reduction in disease activity measures was observed. Patients with baseline axial involvement appear to benefit most from this therapy.

Introduction: Peripheral arthritis and enthesitis characterize the onset and course of JoSpA/ERA. Axial symptoms (ax-symp) are rare at onset and increasingly frequent in patients at risk of ankylosing spondylitis (AS). Unfortunately, most papers, including those mentioning the distinctive term “inflammatory back pain” (IBP) lacked of precision about symptoms.

Objectives: To identify the elements that define ax-symp in children and adolescents with joSpA/ERA.


We extracted information regarding ax-symp, clinical signs, and imaging studies referring to spinal and sacroiliac joints and entheses in joSpA/ERA patients from series of cases, case-control and cohort studies appeared in PubMed from 1966 to 2016.

Results: 58/1405 articles mentioned scarce, ambiguous, and non-specific clinical and imaging data about the involvement of the spine and sacroiliac joints and entheses. Only nine studies described timing; five referred to IBP characteristics, and four to imaging data. The analysis suggests ax-symp occur within five years from onset in up to 50% of the patients; radiographic sacroiliitis is seen and AS diagnosis is made 7.5 to 15 years after onset; syndesmophytes are rare before the of 20 years. MR studies seem to add nothing new yet.

Conclusion: Few papers describe timing and characteristics of ax-symp and radiographic sacroiliitis in children with joSpA/ERA evolving to AS. In contrast, most papers, including AS, do not present enough support to confirm ax-symp in joSpA/ERA patients, including those with AS; the effect of these factors may increase the proportion of false positives in the clinic and in clinical trials.

Introduction: Ankylosing spondylitis (AS) is a chronic systemic inflammatory disease which characteristically involves the axial skeleton, enthesis regions or peripheral joints.As a chronic disease, AS generate high socioeconomic costs and AS cases require lifelong treatment. Severe pain and spine destruction causes high prevalence of work-related disabilities and a decrease in quality of life, which is a huge burden for the case, their families and the society.According to their onset age,the patients was classified to, Juvenile-nset Ankylosing Spondylitis (JAS), whose onset symptoms before the age of 16 years, and Adult-onset Ankylosing Spondylitis(AAS). Clinical phenotype and prognosis of JAS is different from AAS, but up to now scarce information about JAS was reported, especially the related bone metabolism mechanism.

Objectives: To analyse bone metabolic index(BMI) changes on patients with Juvenile-onset Ankylosing Spondylitis(JAS)and their relations with clinical index.

Methods: To collect the clinical data of JAS,such as C-reactive protein (CRP), blood sedimentation (ESR),the disease activity index (BASDAI),functional index (BASFI) and bone mineral density (BMD), detect the serum bone metabolism index,such as Wnt-3a, BMP-2, Dkk-1, 25 (OH) D and ICTP, then group these data and do statistical analysis.

Results: Osteopenia and VitD lack were widespread in JAS. Compared with controls, The elevated Wnt-3a and reduced Dkk-1 levels were not significant in JAS (P > 0.05), and there was no significant correlation between the two indexes and other BMI, course, clinical inflammation index, BASDAI and BASFI.However,the serum ICTP and BMP-2 were increased significantly in JAS, and both the CRP and BMP-2 were positive related with serum Wnt-3a(r was 0.271 and 0.250 respectively, P < 0.05).Correlation analysis shew there was positive correlation between serum 25 (OH) D and hip BMD in JAS(r = 0.383, P < 0.01), and there was negatively correlation between ICTP and BASDAI (r = -0.405 and -0.273 respectively, P < 0.05).Besides,regression analysis shew that both serum 25 (OH) D and the disease course were independent prognostic factors of patients’ hip BMD decreasing, where as CRP and ICTP were also independent prognostic factors of patients’ BASDAI. BMI in JAS with different clinical phenotypes were compared, BMP-2 level was much higher in JAS with hip joint involvement than other groups(P = 0.032), while there was no significant difference in serum 25(OH)D,ICTP,Wnt-3a and Dkk-1 level in all groups(P > 0.05).

Conclusion: Bone metabolism imbalance exists in JAS,and BMP pathway played an important role in the JAS with hip lesions and deserves further research.

Introduction: Systemic onset of juvenile idiopathic arthritis (SoJIA) is a diagnosis of exclusion and required a broad spectrum of differential diagnosis. Patients with malignant hematooncology diseases (HOD) can have the similar to SoJIA symptoms as fever, lymphadenopathy, hepatosplenomegaly, joints pain and arthritis, increased ESR, CRP, anemia and should be discriminated from SoJIA. Due to presence of rheumatic masks children with HOD can be admitted to rheumatologic department.

Objectives: The aim of our study was to find the best cut-off points and clinical signs allowed to discriminate patients who have the rheumatic masks of HOD from patients with SoJIA.

Methods: In the retrospective study were included 86 patients with SoJIA and 21 children with HOD who were admitted in the rheumatology department due to rheumatic masks with initial provisional diagnosis - SoJIA. The HOD group was presented with patients with acute lymphoblastic leukemia (n = 18), neuroblastoma (n = 1) and lymphomas (n = 2). We evaluated the presence of main clinical signs in both groups and detected the best cut-off points of qualitative variables with ROC-analysis and analysis of sensitivity and specificity.
