ABSTRACT

Objective To evaluate the short-term therapeutic effects of DNA immunoadsorbent (IA) combined with glucocorticoid and immune depressant on patients with severe systemic lupus erythematosus(SLE). Methods 32 patients with severe SLE were selected to undergo DNA IA treatment combined with glucocorticoid plus cyclophosphamide therapy, and each patient received IA therapy 3 times, once 2.5 hours, with an interval of 24-48 hours to take another two times of IA. The changes in SLE disease activity index(SLEDAI)score, health status evaluation indexes〔 physiologic functional( PF) and emotional health( MH) scores〕,renal function indexes〔 blood urea nitrogen(BUN)and serum creatinine(SCr)〕 were observed; and anti-double stranded DNA antibody( ds-DNA), immunoglobulin (IgA, IgG, IgM), complements(C3 and C4)and high-sensitivity C-reactive protein (hs-CRP) were examined before and after IA treatment for 2 weeks. Results Two weeks after the combination therapy, the SLEDAI score, BUN, SCr, dsDNA, IgA, IgG, IgM, hs-CRP were significantly lower than those before treatment 〔SLEDAI score : 14.38±3.85 vs. 15.69±1.40, BUN (mmol/L): 11.22±4.78 vs. 16.31±7.90, SCr (μmol/L): 127.02±38.17 vs. 167.25±45.63, dsDNA( U/L): 1.36±0.12 vs. 1.43±0.18, IgA( g/L): 2.41±0.73 vs. 2.59±0.86, IgG( g/L): 16.82±4.83 vs. 21.01±4.84, IgM( g/L): 1.64±0.45 vs. 1.75±0.58, hs-CRP( mg/L): 14.41±2.20 vs. 14.94±2.60, P<0.05 or P<0.01〕; PF score, MH score, complement C3 were increased〔 PF score : 71.19±17.53 vs. 56.66±22.41, MH score : 74.01±15.72 vs. 61.50±17.98, C3( g/L): 0.56±0.09 vs. 0.52±0.10, all P<0.05〕; clinical symptoms were improved significantly, and no significant adverse reactions were found. Conclusion IA combined with medical treatment has shown that it has significant therapeutic effect for treatment of patients with severe SLE, and it may decrease the levels of dsDNA, IgA, IgG, IgM,hs-CRP, and increase the level of complement C3.
