Abstract
Metabolic disorders, such as obesity, type 2 diabetes mellitus (T2DM), and metabolic syndrome (MS) are related to chronic pro-inflammatory conditions. Evidence suggests that heat shock proteins are linked to metabolic disorders. Intracellular HSP70 (iHSP70) is mandatory for normal insulin signalling, and proteostasis, and exerts a powerful anti-inflammatory role. On the other hand, the extracellular (eHSP72) is linked with a pro-inflammatory state and induces insulin resistance in humans. Then, we conducted a systematic review with meta-analysis to summarize the data of HSP70 in people with and without metabolic disorders. PubMed, Embase, Scopus, and Web of Science databases were used. Eligibility criteria included observational and baseline data of experimental studies that assessed iHSP70 and/or eHSP72 in adults with metabolic disorders and healthy people. The risk of bias was assessed by the Newcastle–Ottawa scale. Meta-analysis was performed using a random-effect model and the mean difference was estimated for eHSP72 and the standardized mean difference for iHSP70. A total of 11,255 articles were retrieved, 31 articles were assessed for eligibility and 15 were included for data extraction. There was no difference in eHSP72 between metabolic disorders and healthy controls (mean difference (MD) = 0.11; 95% confidence interval (CIs) = -0.05 to 0.27; I2 = 95%). Subgroup analysis showed higher levels of eHSP72 in T2DM people than healthy ones (MD = 0.32; 95% CIs = 0.17 to 0.47; I2 = 92%). For iHSP70 no difference was found (standardized mean difference (SMD) =—0.24; 95% CIs =—1.62 to 1.15; I2 = 86%). Our results suggest that eHSP72 levels may be dependent on metabolic condition and no difference in iHSP70 levels are attributed to high heterogeneity level between studies (PROSPERO REGISTRATION: CRD42022323514).
