  • Selenium Supplementation for Treatment of Kashin-Beck Disease: A Network Meta-analysis

    ObjectiveTo assess the comparative efficacy of all kinds of selenium supplementation in the treatment of patients with Kashin-Beck disease (KBD) by network meta-analysis. MethodsWe searched seven electronic databases including PubMed, EMbase, The Cochrane Library (Issue 7, 2016), CBM, VIP, WanFang Data and CNKI databases up to July 2016. All randomized controlled trials (RCTs) assessing the effect of selenium supplementation on KBD were included. Two reviewers independently screened literatures, extracted data and assessed the risk bias of included studies, and then meta-analysis was performed by using Stata13.1 software. ResultsA total of 16 RCTs involving 2 883 participants were included. Direct meta-analysis comparison showed that:Compared with placebo or blank group, sodium selenite (OR=5.00, 95%CI 3.21 to 7.78), selenium supplement salt (OR=7.60, 95%CI 2.34 to 24.67), and combination of sodium selenite and vitamin E (OR=11.05, 95%CI 2.61 to 46.80) had higher metaphysis X-ray improvement (P < 0.05). Ranking on efficacy indicated that combination of sodium selenite and vitamin E were highest, followed by selenium supplement salt, sodium selenite, sodium selenite plus vitamin C, vitamin C, and placebo/blank. ConclusionBased on the results of network meta-analysis, selenium supplement (sodium selenite, combination of sodium selenite and vitamin C, combination of sodium selenite and vitamin E, as well as selenium salt) is more effective than placebo or no treatment in promoting the repairement of metaphysis impairment. The effect of combination of sodium selenite and vitamin E are highest.
