Are clinical phenotype and autoantibody profile always concordant in pemphigus? A study in a cohort of pemphigus patients

1) The discrepancy between autoantibody profile and the clinical phenotype, at least in PF patients, appears to be due to non-pathogenic anti-Dsg3 antibodies; 2) in a proportion of patients the relationship between the Dsg1 and Dsg3 ELISA titers and the disease severity was absent; 3) in some patients, the anti-Dsg1 and -3 autoantibodies were lacking at diagnosis, suggesting a role of other antigens in the pathogenesis of the disease and, lastly, 4) the pure cutaneous and mucosal forms tend to respond more efficiently to the therapy than the mucocutaneous forms and have a persistent response.
