Anti-IL1ß-monoclonal antibody in a patient with Muckle-Wells Syndrome and renal transplantation - five years experience
Pediatric Rheumatologyvolume 13, Article number: P147 (2015)
The Muckle-Wells syndrome (MWS) is a rare inherited disease and belongs to the group of cryopyrin-associated periodic syndromes (CAPS). Recurrent fever attacks, myalgia, arthralgia, urticarial rash, headache, conjunctivitis, sensorineural deafness and a severe fatigue syndrome are the typical symptoms of MWS. Due to an unregulated production of IL1 a continuous formation of serum amyloid leads ultimately to the development of AA-amyloidosis, which is life-threatening and in some cases the fatal complication of MWS.
The anti-IL1ß-monoclonal antibody canakinumab has been introduced as a specific therapy in patient with MWS with normal and impaired renal function. There are no long term data about the effect from canakinumab in patients with renal transplantation.
Here we report the five years follow up on a 36-year old female patient with Muckle-Wells syndrome and biopsy proven systemic AA amyloidosis and end stage renal disease. After renal transplantation therapy with canakinumab subcutaneously in a dosage of 150 mg every eight weeks was continued in combination with the immunosuppressive therapy.
Before and after renal transplantation the patient had a very good response to canakinumab with low activity in inflammation markers with an improved quality of life. Over the period of five years the triple immunosuppressive therapy (CSA, MMF, Prednisone) in combination with canakinumab has had no negative effect on activity of MWS and no pharmacological interactions between medications were observed. Even five years after renal transplantation, the patient remains an excellent kidney function without proteinuria. There are no signs of recurrence of AA-amyloidosis in the transplanted kidney.
According to our data, treatment with different immunomodulators in patients with Muckle-Wells syndrome and renal transplantation is safe, feasible and without severe side effects also over a longer time.
