title: Detection of anti-BP180NC16a and anti-BP230 autoantibodies in blister fluid of patients with bullous pemphigoid: the first survey in Greece.
abstract: Bullous pemphigoid (BP) is an acquired bullous disease with an increasing prevalence among elderly people worldwide, including in Greece. Blister formation in most patients with BP is caused by autoantibodies against structural components of the basement membrane zone of the skin, predominantly BP180NC16a and BP230 antigens on the hemidesmosome adhesion complex. Routine diagnostic methods such as histological examination and direct and indirect immunofluorescence are combined to determine diagnosis. In this study, an ELISA was used to measure levels of both anti-BP180NC16A and anti-BP230 autoantibodies in the blister fluid of 13 patients with newly diagnosed BP, before starting treatment. The aim of the study was to evaluate this method as a diagnostic tool in BP. Our results indicate that blister-fluid examination by ELISA can be a useful tool to diagnose bullous pemphigoid, especially in elderly patients who refuse biopsy or have poor venous access.
