Clinical Characteristics and Quality of Life of Seborrheic Dermatitis Patients in a Tropical Country.

Abstract

Background:Seborrheic dermatitis is a common chronic inflammatory skin condition that can have a negative impact on a patient's quality of life. Few studies have been conducted to assess the clinical characteristics of the disease and quality of life of the patients, especially in tropical countries.Aims and Objectives:The aim of this study was to demonstrate the clinical characteristics and quality of life of patients with seborrheic dermatitis in Thailand.Materials and Methods:A cross-sectional study was performed at a university-based hospital and tertiary referral center in Bangkok, Thailand. The validated Thai version of the dermatology life quality index (DLQI) was used to evaluate patients’ quality of life.Results:A total of 166 participants were included. One hundred and forty-seven patients (88.6%) experienced multiple episodes of the eruption. The mean of outbreaks was 7.8 times per years, ranging from once every 4 years to weekly eruption. The most common factor reported to aggravate seborrheic dermatitis was seasonality (34.9%), especially hot climate. The mean (SD) of the total DLQI score was 8.1 (6.0) with a range of 0 to 27. There was no statistically significant difference between the two DLQI categories regarding duration of disease, extent of involvement, symptoms or course of the disease.Conclusion:Although mild and asymptomatic, seborrheic dermatitis can have a great impact on the quality of life. Youth, female gender, and scalp lesions were significantly associated with higher DLQI scores.
