Autoimmune bullous diseases are a heterogeneous group of disorders that can be subdivided according to the level of split formation in the intraepidermal blistering pemphigus diseases and subepidermal bullous disorders.
WASHINGTON — Federal drug officials have long been criticized for failing to force drug makers to complete studies proving that their drugs work as hoped, and Congressional investigators on Monday released yet another report pointing out that some of these studies remain undone many years after being promised.
Bullous pemphigoid (BP), pemphigus vulgaris (PV) and pemphigus foliaceus (PF) are autoimmune bullous diseases characterized by the presence of tissue-bound and circulating autoantibodies directed against disease-specific target antigens of the skin. Although rare, these diseases run a chronic course and are associated with significant morbidity and mortality. There are few prospective data on gender- and age-specific incidence of these disorders.
