A meta-analysis comparing long-term recurrences of toenail onychomycosis after successful treatment with terbinafine versus itraconazole

摘要

As the most frequently used systemic antifungal agents for onychomycosis, terbinafine and itraconazole have both proved to have the conditions of recurrence in various degrees during follow-up period after end of therapy; very little is known about their comparative recurrences after long-term follow-up. We conducted a meta-analysis of available trials to compare the long-term recurrences of toenail onychomycosis after successful treatment with terbinafine versus itraconazole. Meta-analysis was performed by the Review Manager version 5.0.25. Risk ratio and 95% confidence intervals were calculated by the fixed effect model. Five trials and total 251 eligible patients were included in this meta-analysis. The combined risk ratio of the meta-analysis comparing terbinafine with itraconazole for mycological recurrence rate was 0.44 (95% CI 0.29-0.66), which suggests that itraconazole therapy is more likely to produce mycological recurrence compared with terbinafine therapy.
