Evaluation of auto-antibodies in chronic mucocutaneous candidiasis without endocrinopathy


Six patients with chronic mucocutaneous candidiasis (CMCC) were investigated for the presence of auto-antibodies during the course of the infection. Sera were tested for antibodies to native DNA (dsDNA) and denatured DNA (ssDNA), mitochondrial and microsomal antigens, smooth muscle, gastric parietal cells, basal membrane and skin intercellular substance, parathyroid glands, thyroglobulin and microsomal antigen, immunoglobulins and for anti-nuclear antibodies. Auto-antibodies were detected by radioimmunoassay, immunofluorescence, hemagglutination and other routine methods. Tests were performed at the end of the observation period, with the same batches of antigens and at the same time for all patients. Organ-specific antibodies (gastric parietal cells and intercellular substance) were found at low titers in five patients. Anti-smooth muscle antibodies were increased in two patients. In four patients antibodies to ssDNA were elevated. Moreover high titers of anti-ssDNA antibodies correlated well with disease activity after treatment with Ketoconazole in four tested patients. The possibility that C. albicans infection may induce auto-antibodies should be considered in assessing their disease activity significance in other chronic infected patients. The mechanisms of appearance of auto-antibodies and their immunopathological significance in CMCC are discussed.
