Impact of Pemphigus on Sleep Quality: A Prospective, Observational, Monocentric Case-Control Study

Abstract

Introduction: Pemphigus, an autoimmune disorder, significantly impacts the quality of life for those affected. Objective: This study examines the sleep quality in patients with pemphigus, a domain for which the existing literature provides limited data without a focused analysis. Methods: A total of 156 individuals, 52 in the case and 104 in the control group, completed several questionnaires (PSQI, GHQ12, and ABQOL). Disease severity was evaluated using the PDAI scale. Results: The case group exhibited significantly higher levels of psychological distress, reflected in GHQ12 scores (p=0.00), and notably poorer sleep quality compared to controls across various parameters (sleep latency [SL], disturbances [SDi], medication [SM], daytime sleep dysfunction [DSD]), and the global PSQI score (GS)] (p=0.00)]. Significant correlations were observed between PDAI scores and sleep duration (SDu) (p=0.01), SM (p=0.03), SL (p=0.03), and GS (p=0.00). An association was found between the equivalent steroid intake and SDu (p=0.00) as well as GS (p=0.02). No statistically significant correlation emerged between disease duration and PSQI scores. Our findings indicated a correlation between poor sleep quality and cutaneous rather than mucosal manifestations (p=0.01). Pemphigus affects sleep quality. Severe disease showed heightened SDi, correlating with higher steroid doses, and in the chronic phase, the impact seems to be more influenced by the pro-inflammatory stage of the disease. Patients with cutaneous pemphigus exhibit reduced sleep quality compared to those with oral pemphigus. Conclusion: Understanding that pemphigus worsens sleep quality can be beneficial for the holistic management of individuals with this condition.
