Psoriasis Beyond the Skin: A Dermatology Life Quality Index-based Exploration of Life Quality – A Cross-sectional Study as Per STROBE Compliance

Abstract Background: Psoriasis is a chronic and immune-mediated inflammatory skin disease with significant psychological and social repercussions. In addition to physical symptoms, patients often endure stigma, emotional stress, and lifestyle limitations. Objective: To assess the impact of psoriasis on patients’ quality of life (QoL) using the Dermatology life quality index (DLQI) and advocate the integration of QoL assessments in routine clinical dermatology practice. Design: A descriptive, cross-sectional, and observational study was conducted at Ajmal Khan Tibbiya College, AMU, Aligarh. Setting: Outpatient and inpatient departments of Amraz-e-Jild wa Zohrawiya, Ajmal Khan Tibbiya College, Aligarh Muslim University. Participants: Fifty patients clinically diagnosed with psoriasis. Methods: The DLQI questionnaire was administered to assess the QoL across multiple domains including symptoms, daily activities, work, relationships, and treatment impact. Scores were analyzed and categorized into five effect levels from “no effect” to “very severe effect.” Results: About 52% of participants reported severe QoL impairment, 28% moderate, and 12% very severe. Daily functioning and emotional well-being were the most adversely affected domains. Conclusions: Psoriasis imposes a significant burden on patients’ lives beyond visible symptoms. DLQI is a valuable tool in clinical dermatology for recognizing this hidden burden and guiding holistic patient management.
