To Study the Evidence of Linking Adipokines (Adiponectin, Leptin) with Metabolic Syndrome: A Systematic Review

Abstract

Background: A growing body of world health has shown that there is a correlation between derangement of adipokines section and metabolic syndrome, but a small number of studies also refused the data. Considering these aspects, this study is intense in pursuing precise knowledge regarding the same and the conclusion. Aim and Objective: This study investigates the connection between markers of metabolic syndrome and adipokines, particularly leptin and adiponectin. Methods: PubMed, Scopus, and Web of Science databases were used for a thorough literature review. From 2013 to 2023, the terms “adipokines and metabolic syndrome”, “adiponectin and metabolic syndrome”, and “leptin and metabolic syndrome” were searched. This review made use of the preferred reporting items for systematic review and meta. Results: About 3448 previous studies were searched, of which 85 studies fulfilled the inclusion and exclusion criteria. A total of 85 papers comprised this systematic review, and we examined 60 of them. An overvalue of most studies showed that decreased adiponectin levels are linked with a higher risk of metabolic syndrome. However, patients with metabolic syndrome had higher risk levels of both leptin and the leptin-adiponectin ratio. Conclusions: Obesity affects the generation of adipokines, which regulates the many factors of the metabolic syndrome, through unique and linked pathways. Therefore, we conclude that obesity resulting from a high-fat, high-sugar, high-lipid diet may affect various organs, increasing the risk of metabolic diseases and the underlying causes of insulin resistance and triggering an inflammatory response.
