Abstract

Objectives: To investigate the epidemiological and clinical characteristics and quality of life in patients with scalp psoriasis. Subjects and Methods: A descriptive case series study was conducted on 96 patients with scalp psoriasis at Ho Chi Minh City Dermatology Hospital and Nguyen Tri Phuong Hospital from September 2024 to January 2025. Results: The most common initial site of onset was the scalp, accounting for 46.9%, with the two predominant clinical forms being plaque-type and fine scaling-type. Nail involvement was observed in 75% of patients with scalp psoriasis. Topical treatment was the most common therapeutic approach (76%), with the most frequently used regimen being corticosteroids combined with vitamin D analogs (66.7%). Quality of life impairment, as assessed by the Scalpdex score, was higher among females, outdoor workers, individuals residing outside Ho Chi Minh City, patients with cone-shaped scalp psoriasis, and those with lesions in difficult-to-treat areas. Patients receiving biologic therapy had a better quality of life. Disease severity, as measured by BSA, PASI, and PSSI, showed a positive correlation with quality of life impairment based on Scalpdex. Conclusion: The scalp is the most common initial site of onset in patients with psoriasis, significantly impacting quality of life in correlation with disease severity. Factors associated with quality of life impairment include female gender, occupation, place of residence, clinical type of scalp psoriasis, lesion location, and treatment modality.
