Clinical and Immunological Study of 332 Japanese Patients Tentatively Diagnosed with Anti-BP180-type Mucous Membrane Pemphigoid: A Novel BP180 C-terminal Domain Enzyme-linked Immunoassay.

Clinical and Immunological Study of 332 Japanese Patients Tentatively Diagnosed with Anti-BP180-type Mucous Membrane Pemphigoid: A Novel BP180 C-terminal Domain Enzyme-linked Immunoassay. Acta Derm Venereol. 2016 Mar 17; Authors: Yasukochi A, Teye K, Ishii N, Hashimoto T Abstract Diagnosis of anti-BP180-type mucous membrane pemphigoid (BP180-MMP) is frustrated by the difficulty of detecting BP180 reactivity. A total of 721 patients with suspected MMP, selected from a cohort of 4698 patients with autoimmune bullous disease (AIBD), were included in this study. Of these, 332 patients were tentatively diagnosed with BP180-MMP if they showed IgG/IgA reactivity with the epidermal side of 1M NaCl-split-skin and/or positive reactivity with BP180 in at least one of our antigen detection methods. Clinically, a predominance of female patients was diagnosed. Oral mucosal and cutaneous lesions were found in 85.5% and 41.0% of patients, respectively, and frequent treatments were systemic steroids, tetracycline/minocycline and diaminodiphenyl sulfone. Various immunological methods, including a newly developed BP180 C-terminal domain enzyme-linked immunoassay (ELISA), revealed frequent reactivity with BP180 C-terminal and NC16a domains. Some patients reacted with BP180 and other antigens, indicating that BP180-MMP tends to concur with other AIBDs. This large study of patients with suspected BP180-MMP indicates the difficulty of diagnosis of BP180-MM...
