Recent studies indicate that combining phototherapy with topical antioxidants may enhance repigmentation in vitiligo patients, with some therapies achieving higher repigmentation rates compared to monotherapy.
Vitiligo presents a persistent challenge for dermatologists, as monotherapies often fail to achieve substantial repigmentation in many patients. The search for more effective vitiligo treatment strategies has led to a spotlight on combination approaches that address both cellular damage and oxidative stress. A comprehensive network meta-analysis demonstrated that combining phototherapy with topical antioxidants resulted in higher repigmentation rates in vitiligo patients compared to other evaluated regimens, with a Surface Under the Cumulative Ranking (SUCRA) score of 87.7 for achieving ≥50% repigmentation and 89.0 for ≥75% repigmentation.
Earlier findings from the same report also indicated that narrowband UVB, when used in tandem with antioxidants, outperformed other phototherapy modalities. This combination achieved higher mean repigmentation scores than broadband UVB or psoralen plus UVA (PUVA), underscoring the specific advantage of narrowband UVB in optimizing treatment outcomes.
By applying network meta-analysis—a statistical method that compares multiple treatments simultaneously—clinicians can utilize Surface Under the Cumulative Ranking (SUCRA) curves to quantitatively rank the efficacy of combination therapy outcomes. These SUCRA curves placed antioxidant-enhanced phototherapy at the top of the efficacy hierarchy; however, it's important to note that SUCRA rankings reflect relative probabilities and depend on study quality and heterogeneity, which should be considered in clinical decision-making.
Such integration of phototherapy for vitiligo with antioxidant therapy reflects a broader shift in dermatological innovations focused on mitigating oxidative stress in vitiligo patients. While topical calcineurin inhibitors are recommended for localized vitiligo, their repigmentation rates may be lower than those achieved with antioxidant-augmented phototherapy, indicating a need to consider combination therapies in treatment protocols.
Incorporating topical antioxidants into existing phototherapy regimens may refine clinical protocols and set new benchmarks for repigmentation success. Ongoing studies should aim to delineate optimal antioxidant formulations, exposure schedules, and long-term efficacy across diverse patient subgroups to fully harness the potential of these combination therapies.
