Abstrakt: Background: Anti-p200 pemphigoid is a rare autoimmune subepidermal blistering disease. Although the phenomenon of epitope spreading has been reported to be common in anti-p200 pemphigoid, the association between its clinical and immunoserological features has yet to be elucidated.
Objectives: Our aim was to compare the clinical and immunoserological characteristics of anti-p200 pemphigoid patients with and without epitope spreading.
Methods: We performed a retrospective cohort study encompassing 30 patients with anti-p200 pemphigoid between January 2015 and December 2022. The clinical and immunoserological characteristics of anti-p200 pemphigoid were analyzed using combined immunoserological assays.
Results: Epitope spreading was observed in 11 of 30 patients (36.7%) with anti-p200 pemphigoid. Compared with patients in the non-epitope spreading group, patients in the epitope spreading group showed more heterogeneous clinical presentations (P = 0.018), a higher proportion of mucosal involvement (P = 0.003), higher Bullous Pemphigoid Disease Area Index (BPDAI) scores for skin erosions/blisters (P = 0.018), mucosal erosions/blisters (P = 0.001), activity (P = 0.017) and total scores (P = 0.022), and required a higher initial dose of prednisone for disease control (P = 0.040).
Conclusions: This study supported the idea that anti-p200 pemphigoid was prone to epitope spreading. Anti-p200 pemphigoid patients with epitope spreading are more likely to present heterogeneous clinical phenotypes, frequent mucosal involvement, and a more severe and recalcitrant disease course.
