Bullous pemphigoid associated with acute graft-versus-host disease after allogeneic bone marrow transplantation.

A 47-year-old patient was treated with allogeneic bone marrow transplantation (BMT) for chronic myelogenous leukaemia in blast crisis. Three months after the procedure he developed bullous pemphigoid (BP) and symptoms suggestive of BP oesophageal involvement, associated with skin and liver acute graft-versus-host disease. The occurrence of BP is exceptional after BMT.

Frequency of bullous pemphigoid-like antibodies as detected by western immunoblot analysis in pruritic dermatoses.

Background And Design: Ninety-seven patients suffering from a pruritic dermatosis were screened for the detection of bullous pemphigoid (BP) antibodies (ab) using the Western immunoblot (WB) analysis technique.

Results: Twenty-four patients (25%) reacted at least twice with the BP antigen on WB analysis at a 1/10 dilution: seven had typical BP, four had papular BP, 10 had pruritus and prurigo of unknown origin, two had eczema, and one had lichen planus. This corresponds to 13% of BP-type ab in patients who did not fulfill criteria for BP.

Bullous pemphigoid autoantibodies, HIV-1 infection and pruritic papular eruption.

Bullous pemphigoid (BP)-type autoantibodies were found by Western blot (WB) analysis of epidermal extracts in the serum of 38% of HIV-seropositive patients compared with 21% of HIV-seronegative patients with chronic pruritus and 76% of patients with BP. They were further identified as BP autoantibodies (BPab) by immunoprecipitation and immunoelectron microscopy. Their incidence increased from 21% in HIV infection stage II to 37% and 43% in stages III and IV, respectively.
