Background and Objective: Pemphigoid gestationis (PG) is a rare pregnancy-associated autoimmune bullous disease characterized by autoantibodies to the 180 kD bullous pemphigoid antigen (BP180). The clinical spectrum of PG is polymorphic and for diagnostic purposes, a skin biopsy is usually taken demonstrating the deposition of autoantibodies. Patients and Methods: From 2 patients, skin biopsies were obtained for histopathologic and immunofluorescence studies. Circulating autoantibodies were characterized by immunoblotting and ELISA using a recombinant form of the immunodominant BP180 NC16 A domain. Results: The 2 PG patients described here did not show blisters but complained about severe itching. In the first case, PG presented in the first trimester of the second pregnancy as an erythema-multiforme-like disease. The second patient developed urticarial plaques a few days after delivery. PG was diagnosed by the detection of autoantibodies against recombinant BP180 NC16 A by immunoblot and ELISA analysis and confirmed by linear deposits of C3 at the cutaneous basement membrane zone on direct immunofluorecence microscopy. Skin lesions healed with oral prednisolon. Conclusions: In our two patients, nonbullous PG could be diagnosed by serological tests. Immunoblotting and ELISA might be sensitive and specific tools when screening sera of patients with pruritic skin lesions in pregnancy for the presence of autoantibodies to BP180. In some cases, these newer techniques may make a skin biopsy unnecessary.
