Ultrasonography (US) is a useful tool to determine synovial inflammatory involvement, anatomical damage, and “subclinical synovitis” in adult and juvenile pts with RA.
To describe US findings in pJIA pts in CR.
pJIA patients (ILAR'01) with inactive disease (according to Wallace criteria). All patients underwent an ultrasound assessment within the week when clinical examination was done. The U.S. examiner was blinded to clinical findings and the US were carried out on previously affected joints. A Toshiba equipment, model Nemio, transducer 6-12 Hz was used. The following findings were considered pathological in U.S: synovial hypertrophy, effusion and tenosynovitis (by gray scale) and positive Power Doppler (PD). Subclinical synovitis was defined as synovial hypertrophy and positive PD, in absence of clinical arthritis. Demographic, clinical- functional, laboratory and therapeuthical variables were analyzed.
Total assessd n=200
US anormalities n=14 (7%)
Findings (gray escale)
In our series, subclinical synovitis was not detected by U.S. The prevalence of abnormalities by grayscale was 58% pts (11/19), these findings suggest the possibility of persistent inflammation (in US exam) in spite of the absence of clinical finding related with “active disease”.
