Abstract
Detection of anti-desmoglein-1 (anti-DSG-1) and anti-DSG-3 autoantibodies is widely used in the diagnosis of pemphigus. Two validated scoring systems, Pemphigus Disease Area Index (PDAI) and Autoimmune Bullous Skin Disorder Intensity Score (ABSIS), are used for the evaluation of clinical severity. The aim of this cross-sectional study was to interpret the titres of pemphigus autoantibodies in correlation with either total or location-dependent PDAI scores and ABSIS. A total of 35 pemphigus patients were selected and evaluated at 3 time points. Total PDAI and ABSIS seemed useful in pemphigus with cutaneous lesions or in the mucocutaneous form, while location-dependent PDAI and ABSIS scores were useful in the mucosal form. Anti-DSG-1 autoantibodies titres better showed the disease extent in pemphigus with cutaneous only or with mucocutaneous lesions. Anti-DSG-3 autoantibodies titres did not correlate to disease activity.
