Abstract:
Objective To explore the efficacy and safety of Tocilizumab in the treatment of systemic juvenile idiopathic arthritis (sJIA)in children.Methods Twenty-four sJIA patients were collected who were hospitalized at the Department of Rheumatology and Immunity,Jiangxi Provincial Children's Hospital from October 2015 to May 2016,and they received Tocilizumab combined with Methotrexate (MTX) treatment for 12 weeks.The clinical laboratory and physiological indices,including routine blood,liver and kidney function tests,number of joints with active arthritis,number of joints with limited range of motion,physicians and patients assessment of disease activity,childhood health questionnaire,erythrocyte sedimentation rate(ESR),C-reactive protein (CRP),and compliance rates of Pediatrics of American College of Rheumatology(ACR Ped) 30,50,70 were observed after 4,8 and 12 weeks of treatment,and the adverse reactions were recorded.Results After 4 weeks of treatment,the levels of white blood cells,platelet,ESR and CRP in 24 cases of sJIA significantly decreased compared with those of the patients before treatment [(15.1 ± 2.7) × 109/L vs.(24.2 ±3.5) × 109/L,(277 ±73) × 109/L vs.(368 ± 62) × 109/L,(25 ± 12) mm/1 h vs.(75 ± 15) mm/1 h,(20 ± 13) mg/L vs.(64 ± 1) mg/L],and the differences were statistically significant (t =10.08,4.65,70.71,26.78,all P ＜0.05);the hemoglobin was increased dramatically[(110 ± 12) g/L vs.(98 ± 10) g/L],and the difference was statistically significant(t =-3.76,P ＜ 0.05).The compliance rates of ACR Ped 30,50,70 after 4 weeks of treatment were 82％,74％,68％,and they were continuously improved after 8 weeks of treatment (90％,82％,78％)and 12 weeks of treatment (98％,93％,92％),and the differences were all statistically significant (F =7.11,7.29,8.86,all P ＜0.05).The levels of IL-6 after 12 weeks of treatment had no significant change compared with those of the patients pre-treatment [(10.8 ±2.5) ng/L vs.(12.7 ±3.0) ng/L,t =1.96,P ＞0.05].Conclusion Tocilizumab is effective and safe in the treatment of sJIA patients,which can improve the symptoms,signs and laboratory inflammatory activity indexes of sJIA in a short time.
