Abstract:
Objective To summarize the treatment experience of refractory systemic juvenile idiopathic arthritis (JIA) by tocilizumab, and to explore the cost-effective treatment. Methods The clinical data of 6 pediatric patients with refractory systemic JIA treated by tocilizumab from 2014 to June 2016 were retrospectively analyzed in the aspects of course and effectiveness of tocilizumab, steroid reduction, adverse reaction, and growth. Results The median age of the six patients (3 males and 3 females) was 6 years, and the course of disease were from 16 to 63 months. All patients were treated by other immunosuppressive agents or biological agents in addition to steroid and traditional anti-rheumatic drug therapy. The courses of tocilizumab treatment were from 7 to 26 months and the median time was 9.5 months. All 6 patients responded to tocilizumab and achieved the clinical remission at different time. After the induced remission, the interval of the treatment intervention was increased from 2 weeks up to 4 weeks in 3 cases, and no disease activity was observed. Except one case, another 5 cases reduced and stopped the use of hormones at 5.8 months after tocilizumab treatment. After hormones was reduced and discontinued, the growth was improved. All 6 patients had no serious adverse reactions. Conclusions Tocilizumab is safe and effective for patients with refractory JIAs. The steroid can be reduced in short time to improve growth. After remission is induced, the interval of the treatment intervention could be prolonged.
