Abstract

Background: Pemphigus is a rare autoimmune disease characterized by the formation of blisters on the skin and mucous membranes, caused by autoantibodies against desmoglein, a key protein in cell adhesion. This study aims to compare demographic and clinical criteria between male and female patients with pemphigus referred to a referral hospital, utilizing data from the pemphigus diseases registry. Method: This retrospective cross-sectional analysis focused on several key aspects age at disease onset, severity (measured by the Pemphigus Disease Area Index [PDAI]), types of pemphigus, duration of disease, and diagnostic criteria including the presence of antidesmoglein antibodies and findings from direct immunofluorescence (DIF). By examining these variables among a cohort selected based on their diagnosis of pemphigus, the study aimed to identify significant gender differences in disease manifestation, diagnosis, and progression. This approach is crucial for tailoring more effective gender-specific management and treatment strategies for this rare autoimmune condition. Results: In a comprehensive analysis of 1218 pemphigus patients in the year 2021 from the hospital’s registry, comprising 543 males (44.6%) and 675 females (55.4%), significant gender differences were identified in 9 out of 44 variables examined. The study revealed that males had a higher age at disease onset, more frequent clinical manifestations in the head, neck, and trunk areas, and greater severity of disease as measured by the PDAI score compared to females. Conversely, females exhibited higher instances of mucosal manifestations and a higher PDAI score for mucosal erosion blister of the lower gingiva. No significant gender differences were found in 21 variables, including the overall age of patients, specific clinical manifestations across various mucous membranes, types of pemphigus, and PDAI scores for mucosal erosions in particular locations, indicating a nuanced gender impact on the presentation and severity of pemphigus that necessitates tailored clinical approaches. Conclusion: The study highlights significant gender differences in the presentation and severity of pemphigus, underscoring the importance of gender-specific approaches in the diagnosis and management of this condition. The findings contribute valuable insights into the complex nature of pemphigus and underline the necessity for further research to understand the underlying mechanisms driving these differences. © 2025 Elsevier B.V., All rights reserved.
