Mucous Membrane Pemphigoid and Pseudopemphigoid

Research output: Contribution to journalArticle

Abstract

Purpose: To describe the clinical characteristics of patients with mucous membrane pemphigoid (MMP) and pseudopemphigoid. Design: Retrospective cohort study. Participants: Two hundred eighty consecutive patients referred for the evaluation of possible ocular MMP from January 1, 1985, to December 31, 2001. Methods: Information on patients presenting for evaluation of possible MMP was entered prospectively into a database, which was supplemented by a retrospective chart review. Mucous membrane pemphigoid was diagnosed in patients with a compatible clinical picture by the linear deposition of antibodies to the basement membrane zone (BMZ) on direct immunofluorescent analysis of a mucous membrane biopsy specimen or by the presence of circulating autoantibodies to epithelial BMZ. Main Outcome Measures: Demographic and clinical characteristics of MMP and pseudopemphigoid; risk of ocular MMP among patients presenting with extraocular MMP without ocular disease. Results: Among patients with ocular MMP, extraocular disease was common (82.4% of patients). The risk of ocular involvement among patients with MMP seen without ocular disease was approximately 5% per year over the first 5 years of follow-up (cumulative risk at 5 years, 22%). Although immunohistologic confirmation of the diagnosis was obtained in all patients, the initial conjunctival biopsy was positive for MMP in 80% of the patients diagnosed with ocular MMP. The most frequent presumed causes of pseudopemphigoid were topical glaucoma medications (28.3%), rosacea blepharoconjunctivitis (20.0%), atopic keratoconjunctivitis (8.3%), and conjunctival lichen planus (8.3%). Conclusions: Patients with ocular MMP typically have other systemic manifestations of MMP. Patients who are initially seen with extraocular MMP without ocular involvement are at risk for ocular disease developing. The clinical characteristics of ocular MMP and pseudopemphigoid are similar; therefore, immunohistologic evaluation of biopsied tissue is needed to confirm the diagnosis of MMP.
