Abstract

Background: Psoriasis and atopic dermatitis are two common chronic inflammatory skin diseases with distinct immunological pathways but potentially overlapping epidemiological patterns. Recent evidence has highlighted shared systemic inflammatory risk and disease burden, making comparative characterization valuable for clinical decision-making. Objective: To describe and compare epidemiological and clinical features of patients with psoriasis and atopic dermatitis. Materials and Methods: A cross-sectional study was conducted at Ho Chi Minh City Dermatology Hospital from February to October 2025. Patients were recruited by convenience sampling and matched for age and sex at a 1:1 ratio. Data collected included age, sex, BMI, disease duration, and severity measures (PASI for psoriasis and SCORAD for atopic dermatitis). Results: The two groups showed similar age and sex distributions, with most participants being middle-aged. BMI and lifestyle factors such as smoking and alcohol consumption were not significantly different. Psoriasis patients had longer disease duration, and severe PASI scores were associated with early onset, hypertension, and nail involvement. Atopic dermatitis cases were predominantly mild to moderate based on SCORAD. Conclusion: Psoriasis and atopic dermatitis share comparable epidemiological characteristics, while clinical differences are mainly reflected in chronicity and severity. Findings may support patient stratification and targeted management strategies.
