Abstract
Aim: To assess the correlation between the levels of anti-desmoglein-1 and anti-desmoglein-3 autoantibodies and disease severity in pemphigus patients.
Materials and methods: Thirty-eight pemphigus patients aged 30 to 87 years were included in the study. All patients underwent clinical examination, pemphigus disease zone index assessment, histopathological and direct immunofluorescence tests, and assessment of desmoglein-1 and desmoglein-3 autoantibodies by enzyme-linked immunosorbent assay.
Results: Twenty-eight out of 38 serum samples exceeded the cut-off value of anti-desmoglein-1, and 26 of 38 sera had positive anti-desmoglein-3 antibodies. One serum from 38 controls had positive anti-desmoglein-1 antibodies. Seven (18.4%) patients experienced a mild course of the disease, 16 (42.1%) patients experienced moderate, and 15 (39.5%) patients suffered from severe pemphigus. A significant correlation between disease severity and both autoantibody levels was observed, but there were exceptions.
Conclusions: There is a significant correlation between anti-desmoglein antibodies and disease severity in the entire group, but there are also discrepancies in some cases.
