    Abstract:
    BACKGROUND: The emergence of bacterial resistance to commonly used antibiotics, such as macrolides, is complicating the management of respiratory tract infections (RTIs). Telithromycin, a ketolide antimicrobial structurally related to macrolides, is approved for the treatment of community-acquired RTIs, and shows lower pathogen resistance rates. The purpose of this study was to compare the efficacy and safety of telithromycin with clarithromycin, a macrolide routinely used as therapy for RTIs. METHODS: We performed a meta-analysis of relevant randomized-controlled trials (RCTs) identified in PubMed, the Cochrane Library, Embase, CNKI and VIP databases. The primary efficacy outcome was clinical treatment success assessed at the test-of-cure time in the per-protocol population, and the primary safety outcome was drug related adverse effects. RESULTS: Seven RCTs, involving 2845 patients with RTIs, were included in the meta-analysis. Oral telithromycin and clarithromycin showed a similar clinical treatment success in modified intention to treat and per-protocol population (cure and improvement) (odds ratios (ORs): 0.84, 95% confidence intervals (CI): 0.64 - 1.11 and OR: 1.14, 95%CI: 0.71 - 1.85, respectively). Similar findings were obtained for secondary efficacy outcomes: clinical treatment success at a late post-therapy visit (OR: 0.92, 95%CI: 0.57 - 1.48) and microbiological treatment success at the test-of-cure time (OR: 1.14; 95%CI: 0.71 - 1.85). The safety outcome analysis indicated telithromycin had a similar risk of drug-related adverse effect and serious adverse effect with clarithromycin. CONCLUSIONS: Our findings indicate that oral telithromycin and clarithromycin have similar treatment efficacy and adverse effect. The advantages of lower antimicrobial resistance rates, once-daily short-duration dosing and reported lower health-care costs make oral telithromycin a useful option for the empiric management of mild-to-moderate RTIs.
