Post-Traumatic Stress in Vitiligo Patients: A Neglected but Real-Existing Psychological Impairment.

BACKGROUND

Vitiligo is the most common depigmentation disorder. This disease causes disfiguration and induces psychological burdens, leading to significantly impaired quality of life. Limited research about disease-related post-traumatic stress (PTS) has been conducted in vitiligo patients.

OBJECTIVE

To evaluate the prevalence, severity, and risk factors of post-traumatic stress in vitiligo patients.

METHODS

This case-control study was performed from January 2021 to April 2021. A survey questionnaire including baseline information, post-traumatic stress symptoms evaluation, life quality evaluation was conducted. According to the severity of post-traumatic stress symptoms, patients were grouped and compared. The logistic regression model was conducted to analyze the risk factors for post-traumatic stress disorder (PTSD).

RESULTS

A total of 337 patients were included. A 30.3% of vitiligo patients (102/337) in present cohort had PTS and 12.5% patients (42/337) were confirmed for developing into PTSD. The multivariate logistic regression revealed educational level<university (OR=2.32, 95% CI=1.97-2.93, P=0.003), vitiligo in face and neck (OR=2.65, 95% CI=2.08-3.12, P=0.008), vitiligo in feet and hands (OR=1.86, 95% CI=1.54-2.12, P<0.001) and surgical treatment (OR=3.53, 95% CI=3.12-4.02, P<0.001) were risk factors for PTSD. PTS severity was significantly associated with vitiligo disease activity score (rho=0.54, R2=0.29, P=0.002), vitiligo area scoring index score (r=0.55, R2=0.30, P=0.012), and dermatology life quality index score (r=0.61, R2=0.37, P=0.004).

CONCLUSION

Vitiligo-related PTS is prevalent in vitiligo patients and causes psychological impairment. Dermatologists should realize and identify this condition carefully and offer proactive intervention to improve patients' quality of life.
