Prevalence of Sleep Disturbances in Bullous Pemphigoid Patients.

Bullous pemphigoid (BP) is the most common autoimmune blistering disorder. The incidence of BP has increased due to increased life expectancy, particularly in developed countries, which can be associated with multiple geriatric comorbidities and polypharmacy. Epidemiological studies of BP have shown that the incidence ranges from 2.5 to 42.8 cases/million/year in European countries. BP affects older adults with multiple comorbidities, primarily neurological diseases such as multiple sclerosis, dementia, Parkinson's disease, epilepsy, and stroke, which are usually diagnosed before BP. Diagnosis is based on clinical suspicion combined with immunopathological investigations. The clinical chronological course is characterized by relapses and remissions. The goals of PB treatment are to stop the development of new skin lesions, healing of old lesions, and symptomatic therapy.
