Abstract
BACKGROUND: Photodynamic therapy (PDT) has emerged as the effective new method to treat acne vulgaris. However, no meta-analysis has been published on PDT for acne vulgaris currently. OBJECTIVE: The current meta-analysis and systematic review were carried out to assess the safety and effect of PDT on treating acne vulgaris. METHODS: The electronic databases, including EMBASE, Cochrane Library, and MEDLINE, were systemically retrieved to identify relevant articles for meta-analysis. The primary outcome included mean percentage reduction in the inflammatory lesion count (MPRILC), while the secondary outcome included the total effective response (TER). RESULTS: Altogether 13 randomized controlled trials (RCTs) involving 701 subjects had been enrolled into the current meta-analysis. PDT had certain effect on acne vulgaris in terms of the outcomes of MPRILC (MD: 15.97, 95% CI: 11.93 to 20.00, P < .00001) and TER (RR: 1.55, 95% CI: 1.38-1.74, P < .00001). Totally, 6 articles had been evaluated to have a low bias risk overall. Results of sensitivity and subgroup analyses were similar to meta-analysis results, reflecting the result reliability in this meta-analysis. CONCLUSIONS: PDT is beneficial for improving the clinical efficacy of inflammatory acne vulgaris, which can be widely used to treat inflammatory acne vulgaris in clinic.
