The efficacy of combined phototherapy with topical therapy in vitiligo: a network meta-analysis.

BACKGROUND

The comparative effects of phototherapy and topical therapy in patients with vitiligo remain unclear. A network meta-analysis (NMA) was conducted to assess which combination therapy was more beneficial for patients with vitiligo.

METHODS

This study analyzed phototherapy, including narrowband ultraviolet B (NB-UVB) and 308-nm excimer laser/light (EL) combined with topical therapies. Randomized controlled trials were sourced from PubMed, Embase, and Cochrane Library. Data analysis was based on a random-effects model, and surface under the cumulative ranking (SUCRA) curves employed to assess the efficacy of the interventions.

RESULTS

This NMA included 27 trials, with a total of 2417 lesions (patches). According to the results of the SUCRA, for achieving ≥50% repigmentation, the top three combination therapies were phototherapy combined with antioxidants (SUCRA 87.7), corticosteroids (SUCRA 69.6), and calcineurin inhibitors (SUCRA 52.5), while for ≥75% repigmentation, the leading therapies were phototherapy combined with antioxidants (SUCRA 89.0), calcineurin inhibitors (SUCRA 70.3), and fractional CO2 laser (SUCRA 63.6).

CONCLUSIONS

This meta-analysis suggests that combining phototherapy with topical antioxidants, corticosteroids, or calcineurin inhibitors may offer superior outcomes for vitiligo patients. This study provides a reference for clinicians to develop personalized treatment plans for patients with vitiligo.
