  • Efficacy of Antidepressants in Preventing Poststroke Depression: A Meta-analysis

    ObjectiveTo systematically review the efficacy of antidepressants in the prevention of poststroke depression (PSD). MethodsWe searched The Cochrane Library (Issue 2, 2015), PubMed, MEDLINE, EMbase, CNKI and VIP databases to collect randomized controlled trials (RCTs) about antidepressants in preventing PSD from inception to April 2015. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies. Then, meta-analysis was performed using RevMan 5.3 software. ResultsA total of 26 RCTs involving 2 190 patients were included. The results of meta-analysis showed that:compared with the control group, the antidepressants group could significantly reduce the incidence of PSD (OR=0.24, 95%CI 0.17 to 0.36, P<0.000 01). Subgroup analysis based on types of drugs showed that:the selective serotonin reuptake Inhibitor (SSRI) could significantly reduce the incidence of PSD (OR=0.23, 95%CI 0.15 to 0.37, P<0.000 01). Subgroup analysis based on length of time showed that antidepressants could decrease the incidence of PSD in short term (OR=0.11, 95%CI 0.06 to 0.19, P<0.000 01), middle term (OR=0.31, 95%CI 0.21 to 0.46, P<0.000 01) and long term (OR=0.30, 95%CI 0.19 to 0.49, P<0.000 01). In addition, there was no statistical difference in the incidence of adverse effect between the antidepressants group and the control group (P>0.05). ConclusionAntidepressants is effective in the prevention of PSD, and may not affect patient's life quality. Due to the limited quantity and quality of included studies, more high quality studies are needed to verify the above conclusion.
