Objective To systematically evaluate the efficacy and safety of tacrolimus and glucocorticoid for oral lichen planus (OLP).
Methods The Cochrane review’s method was adopted and computer-based retrieval was performed on The Cochrane Library, MEDLINE, EMbase, CBM, and CNKI (from their establishment to November 2010) to collect randomized controlled trials (RCTs) comparing the clinical efficacy of tacrolimus in treating OLP with that of triamcinolone. The study was selected according to the inclusion and exclusion criteria, the data were collected, and the methodological quality of the included studies was evaluated. The RevMan 5.0.25 software was applied for statistical analyses.
Results Four RCTs involving 164 patients were included. Two studies showed that the tacrolimus effectively reduced lesion area and alleviated pain of patients with OLP. The results of meta-analyses showed that the total effective rate of tacrolimus was not higher than that of glucocorticoid (OR=4.38, 95%CI 0.67 to 28.73), and there was no significant difference between the tacrolimus group and the glucocorticoid group in adverse events during the treatment session (OR=3.49, 95%CI 0.49 to 24.84), and there was no significant difference in recurrence rate between those two groups (OR=0.82, 95%CI 0.27 to 2.46).
Conclusion Topical tacrolimus can remarkably improve the OLP sign (lesion area) and symptom (pain), which is in line with the findings of other non-RCTs. The current evidence proves that the tacrolimus is similar to glucocorticoid in terms of the total effective rate of treating OLP, the incidence of side reaction during treatment, and the recurrence rate after stopping treatment. Some studies included in this systematic review apply different assessment methods, hence more RCTs with high-quality, multi-center, and therapeutic evaluation indexes with corresponding evaluation methods are required to provide more reliable evidence.
