Psychosocial and quality-of-life factors associated with depigmentation therapy for vitiligo

BACKGROUND: There is a paucity of data examining the psychosocial factors relevant to depigmentation therapy, an irreversible treatment for vitiligo. This study explores patients’ perspective and experience while undergoing depigmentation therapy and quality-of-life effects of such therapy. METHODS: An online instrument assessing the impact of depigmentation therapy on various psychosocial variables and including the validated Dermatology Life Quality Index (DLQI) were administered to two groups of participants with vitiligo: (1) those who are currently undergoing or have completed depigmentation therapy and (2) those with vitiligo who have not undergone depigmentation therapy but had considered it. Data were collected on psychosocial factors such as length of time until depigmentation therapy was offered, duration, financial burden, level of satisfaction, impact on life activities, and challenges faced during and after depigmentation therapy. DLQI scores were also measured. RESULTS: Thirty-five vitiligo patients who did not undergo depigmentation and 42 patients who did undergo depigmentation therapy were included in the study. Baseline characteristics were comparable between groups. Mean DLQI was higher for patients who did not undergo depigmentation than for those who underwent depigmentation (10.2 versus 5.3, p = 0.002), indicating worse quality-of-life in those not depigmenting. Patients who underwent depigmentation reported significantly less discomfort in various social situations after undergoing depigmentation therapy compared to how they felt before undergoing therapy and reported significantly less discomfort in these situations than patients who did not undergo depigmentation therapy. CONCLUSIONS: Despite potential challenges, depigmentation therapy appears to augment quality-of-life across various domains in individuals with vitiligo.
