Abstract

Different adipokines secreted from adipose tissue, exert a range of physiological effects. The aim of present systematic review and meta-analysis was to critically investigate the consequence of bariatric surgery on circulating adipokines, that is, adiponectin, leptin, visfatin, resistin, plasminogen activator inhibitor, and chemerin. After systematically checking the following electronic databases: ISI web of Science, Scopus and PubMed without limitation in time and language up to February 2019, a pool based on a random effect model was established. Eighty-five eligible studies were entered for quantitative analysis. Our meta-analysis revealed that circulating adiponectin increased significantly after bariatric surgery [Standardized mean difference (SMD)=1.401, 95% CI: 1.101, 1.701, p<0.001]; whilst leptin (SMD=-2.178, 95% CI: -2.433, -1.923, p<0.001), PAI-1 (-14.928 ng/ml 95% CI: -21.794, -8.063, p<0.001), and chemerin (-50.238 ng/ml 95% CI: -85.708, -14.768, p<0.001) decreased. However, serum visfatin (2.05 ng/ml, 95% CI: -5.07, 9.17, p=0.573) and resistin (-2.080 ng/ml, 95% CI: -5.352, 1.192, p=0.21) were unchanged. In conclusion, bariatric surgery is associated with a reduction in specific adipokines including leptin, chemerin, and PAI-1, whereas adiponectin is raised, adaptations that could be indicative of improved fat mass and function. © 2020 EDP Sciences.
