Patients' perspective on current treatments and demand for novel treatments in vitiligo.

BACKGROUND

The treatment of non-segmental vitiligo (NSV) remains a challenge. Current treatments often achieve suboptimal clinical results. To improve these treatment results, several new therapies are being developed and investigated. There is, however, little evidence on the actual need for novel therapies.

OBJECTIVE

To assess patients' perspective on current and novel therapies for vitiligo.

METHODS

A prospective questionnaire study was conducted in a large cohort of vitiligo patients that consecutively visited the outpatient clinic of the Amsterdam University Medical Centre between April 2017 and January 2019. Patients were requested to fill in a digital questionnaire on patient characteristics, disease burden, quality of life, efficacy and satisfaction of current treatments and aspects regarding new treatments.

RESULTS

A total of 325 vitiligo patients completed the questionnaire (60% response rate). Of the respondents, 94% believed that new and improved treatments are needed and 86% would be willing to participate in clinical trials investigating a new therapy. Sixty-nine per cent would agree on taking weekly injections if it led to effective treatment results. Of the patients that had received therapy before, 49% reported that the current treatments were not effective and 50% was not satisfied with the current treatments. Sixty-seven per cent of the patients experienced facial lesions as an extreme burden, whereas this was, 25%, 12% and 10% for lesions on the hands, trunk and feet, respectively. The emotional burden score was significantly higher in dark skin types compared with light skin types (respectively, 8 vs 5, U P < 0.05).

CONCLUSION

There is a substantial need for new vitiligo therapies. A considerable number of patients in our study are dissatisfied with current treatments and are emotionally burdened by the disease. Moreover, the vast majority demands novel treatments and is willing to participate in clinical trials.
