A study was conducted on 130 patients suffering from skin lesions which included psoriasis, lichen planus, DLE, pemphigus, vitiligo and alopecia areata. Forty age-and-sex-matched healthy individuals served as control. Serum IgG, IgM, and circulating immune complexes (CIC) were estimated. Significant increase in serum IgG (1937.2 1030.43 mg%) and IgM (232.12 136.98 mg%) was observed in all the skin lesions when compared with controls except in lichen planus where they were significantly lowered, values being 580.61 77.35 mg% and 66.88 6.59mg% respectively. CIC levels were significantly raised (P<0.00 1) in various skin lesions (40.4923.29) when compared with controls (17.68 3.21), but no significance was observed in lichen planus( 17.72 4.28). Serum IgG, IgM and CIC were statistically significantly altered depending on the extent of the lesion and lowered significantly to almost normal values following treatment, thereby confirming the role of immunity in the pathogenesis of these skin disorders.
