Shedding Light on Shadows: A Cross-Sectional Analysis of Genital Psoriasis and Its Effects on Thai Individuals.

Abstract

Background: Limited knowledge exists about genital psoriasis in Thai individuals.

Objectives: This study aimed to assess the clinical features of genital psoriasis and its effects on quality of life and sexual health in Thai patients.

Materials and methods: A cross-sectional, self-administered question-based study was conducted at Siriraj Hospital. Participants were psoriasis patients older than 18 years of age with past or current genital involvement. The study assessed quality of life and sexual health.

Results: Among the 50 patients, 33 (66%) were female. The mean (standard deviation) age was 45.4 (±13.4) years. Genital psoriasis was active in 34% of the participants. The mons pubis (48.5%) and labia majora (18.2%) were the most frequently affected sites in females, while in males, the penile shaft (52.9%) and glans (47.1%) were the most common sites. Itch-related symptoms predominated, affecting 82% of patients. The median dermatology life quality index score was 6.5 for females and 10 for males. A sexual health survey revealed that 54% of participants had low self-esteem. This issue was more pronounced in males, with 76.5% reporting lower self-esteem compared to 42.4% of females (P=0.022). Males were also more inclined to postpone or avoid marriage (47.1% vs. 15.6%, P=0.038) and more embarrassed about sexual activities (63.6% vs. 14.3%, P=0.017). In addition, males were more inclined to avoid sexual encounters due to their genital condition. Notably, 42.9% of all patients had never disclosed to a doctor that they had genital psoriasis.

Conclusions: Genital psoriasis impacts quality of life and sexual function, with male patients being particularly impacted. Improved awareness of these issues among health professionals might increase patient satisfaction.
