DNA immunoadsorption for childhood-onset systemic lupus erythematosus
ABSTRACT
We present a retrospective review of DNA immunoadsorption (DNA-IA) therapy on clinical symptoms as well as indicators in pediatric cases with systemic lupus erythematosus (SLE), and follow up the short-term curative effects. 16 SLE cases were treated by DNA-IA for 3 times every other day. We observed the changes on clinical manifestations and immunological indicators, in order to compare the alteration of these indicators including clinical manifestations, Systemic Lupus Erythematosus Disease Active Index (SLEDAI) scores, 24 hurinary protein excretion, autoantibodies, serum IgG and complement C3. 13 cases were followed up regularly, within 3 months after DNA-IA therapy, 12 cases of clinical manifestations improved (92.3%). SLEDAI scores in 10 cases decreased from (16.20 ± 12.54) to less than 5 (76.9%), 8 cases of ANA, anti-DNA antibodies were negative (61.5%), 13 cases with IgG level in serum recovered to normal (10.39 ± 4.38) g/L, C3 level rose to normal (1.06 ± 0.23) g/L. 3 to 6 months after IA, clinical manifestations and laboratory examinations in all cases got maximum improved. 9 months after IA, SLEDAI score in 2 cases (15.4%) rose to more than 5, anti-DNA antibody in 2 cases (15.4%) became positive, and 1case (7.7%) with serum C3 decreased again. 2 cases died from multiple organs dysfunction within 3 to 6 months after IA. No serious complications were found during DNA-IA. We recommend that DNA immunoadsorption is a safe and effective therapy for active childhood-onset SLE, which could improve clinical symptoms, eliminate ANA and anti-DNA antibodies. Combining with corticosteroids and immunosuppressive drugs, DNA-IA could significantly reduce the activity of disease and protect vital organs function in the short term.
