title: [Effects of Topiramate for atypical antipsychotic-induced body weight gain and metabolic adversities: a systematic review and meta-analysis].
abstract: OBJECTIVE
  To systematically determine the effectiveness of Topiramate to counteract atypical antipsychotic-induced body weight gain and metabolic adversities in patients with psychiatric disorders.
  
  
  METHODS
  A literature search using MEDLINE, EMBASE, PsycINFO, The Cochrane Library, CNKI, CBM and WanFang Data for randomized, open and double-blind, placebo-controlled trials of Topiramate targeting atypical antipsychotic-induced weight gain was performed.Two reviewers independently screened literature according to the inclusion and exclusion criteria, extracted data, and assessed methodological quality of included studies.Then meta-analysis was performed using RevMan 5.2 software.
  
  
  RESULTS
  A total of 10 RCTs was included, consisting of 453 subjects. The results of meta-analysis showed that: compared with placebo, Topiramate was moderate effective in reducing antipsychotics-related weight gain (WMD=-1.82 kg (95%CI: -2.65--0.99), P<0.000 1), BMI increase (WMD=-1.31 kg/m(2) (95%CI: -1.69--0.93), P<0.000 01) and fasting glucose increase (SMD=-1.15 (95%CI: -1.50--0.79), P<0.000 01); but can not regulate the lipid metabolic disorders (Cholesterol: SMD=-0.23 (95%CI: -0.81-0.35), P=0.44); Triglycerides: SMD=-0.28 (95%CI: -0.75-0.19), P=0.24; HDL: SMD= 0.01 (95%CI: -0.52-0.53), P=0.98); LDL: SMD=-0.39 (95%CI: -0.89-0.11), P=0.13). Meanwhile, when compared with placebo, Positive and Negative Syndrome Scale (PANSS) in patients with schizophrenia did not show obviously clinical improvement in concomitant Topiramate group.
  
  
  CONCLUSIONS
  Topiramate can prevent and/or treat atypical antipsychotic induced weight gain and glucose disorder, but current evidence does not support the effect of Topiramate in lipid metabolic regulation and the clinical symptoms improvement assessed by PANSS.
