We monitored the disease activity by documenting the clinical symptoms, recording muscle-related parameters (electromyography, serum creatine kinase, histopathology), and by determining circulating autoantibodies and serum levels of IL-6, sIL-2R, sTNF-a-R, sICAM-1, and sCD8. 7/19 patients responded to IVIG. They had severe skin but only moderate muscle involvement, no autoantibodies, and no malignancy. IVIG-nonresponders had severe skin and muscle disease, concomitant with autoantibodies and/or malignancy. sIL-2R levels were initially elevated in all patients but reverted to normal in IVIG-responders only. Creatine kinase-levels and other parameters did not correlate with disease activity and/or treatment response. IVIG is effective in selected dermatomyositis patients. sIL-2R serum levels appear to be useful predictors of IVIG-induced treatment response and disease activity. | lld:pubmed |
