Abstract:
Objective:To evaluate the short-term efficacy and safety of HA280 immunoadsorption (IA) column in idiopathic inflammatory myopathies (IIM).Methods:The clinical data of 72 patients with IIM admitted to the Department of Rheumatology of Xiangya No.2 Hospital of Central South University from January 2015 to March 2018 were analyzed. Of these patients, 22 patients were treated with HA280 immunoadsorption column for three times (the immunoadsorption group) and 50 patients were treated with drugs only (the control group). The changes of clinical symptoms and signs, autoimmune antibodies, myocardial enzyme spectrum, the inflammatory markers [erythrocyte sedimentation rate (ESR), C-reactive protein (CRP) and ferritin], immunoglobulin, complement, other biochemical indexes and pulmonary images of the patients were detected and analyzed before and after the treatment. And then the data were analyzed by Chi-square test, samples t testand Wilcoxon rank sum test. Results:Compared with the control group, the symptoms and signs were obviously improved after treatment with HA280 immunoadsorption column. In particular, the clinical improvement rate of non-specific myositis (89%, 16/18) was higher than that of the control group [(58%, 22/38), χ2=5.379, P<0.05]. And the clearance of autoantibody (control group) was grade 39.41 in average, 28.38 in average in the immunoadsorption group( Z=-2.51, P=0.01), myocardial enzyme spectrum [control 717(1 564) U/L, immunoadsorption group 126(432) U/L , Z=3.09, P<0.01], the inflammatory markers such as ESR [the control group was 24(22) mm/1 h, the immunoadsorption group was 10(7) mm/1 h, Z=-3.0, P=0.003] and immunoglobulin G [the control group was 11(5) g/L, the immunoadsorption group was 9(2) g/L, Z=-4.8, P=0.001] and immunoglobulin M [the control group was 0.9(0.4) g/L, the immunoadsorption group was 1.2(0.8) g/L, Z=-2.0, P=0.05]. Moreover, the lung CT scan showed that pulmonary lesions of the patients in the immunoadsorption group (89%, 17/19) was much more improved than the control group [(61%, 27/44), χ2=4.98, P<0.05]. No serious adverse reactions occurred. Conclusion:HA280 immunoadsorption therapy can significantly clear the autoantibodies, decrease muscle enzymes, inflammatory markers and immunoglobulin, improve lung images of some patients in a short time. It has been shown that it is safein patients with IIM. HA280 immunoadsorption therapy could be an effective treatment for IIM.
