Abstract
An immunofluorescent study was carried out on skin biopsies from 12 leprosy patients who had been suffering from the disease for periods of one to 30 years; all were treated with dapsone and clofazimine at one stage. Skin biopsies made from reactive nodular lesions showed that all 12 had IgG deposits and seven had IgM deposits in the dermal-epidermal junction. No IgA, IgE, C3 and fibrinogen were found deposited in any biopsy. All patients had significantly raised levels of serum immunoglobulins and rheumatoid factor. Anti-epithelial (eight patients) and anti-nuclear (three patients) antibodies were also found. The possible role of autoantibodies in the present findings is discussed.
