Swimming intervention alleviates insulin resistance and chronic inflammation in metabolic syndrome.

ABSTRACT: In view of the high incidence of metabolic syndrome and the role of exercise in promoting metabolic disorders, the present study aimed to investigate the therapeutic effects of swimming intervention on metabolic syndrome. In the present study, a total of 100 patients with metabolic syndrome and 100 healthy individuals were included. Fasting blood was extracted from each participant, and the serum levels of interleukin (IL)-1, high sensitivity C-reactive protein (hs-CRP), tumor necrosis factor ? (TNF-?) and IL-8 were measured by sandwich enzyme-linked immunosorbent assay. Patients were randomly divided into five groups (groups A-E). Patients in group A was treated with conventional drug treatment. Besides conventional treatment, patients in groups B-E were also subjected to swimming intervention for 15, 30, 45 and 60 min each time, respectively, four times a week for 3 months. Changes in the homeostatic model assessment of ?-cell function and insulin resistance (HOMA-IR) score, and in the serum levels of IL-1, hs-CRP, TNF-? and IL-8 were recorded. Furthermore, muscle tissues were collected from patients, and the expression levels of insulin receptor substrate-1 (IRS-1), glucose transporter type 4 (GLUT4) and protein kinase B (Akt) in the tissues were detected by western blot assay. The results revealed that HOMA-IR and the serum levels of IL-1, hs-CRP, TNF-? and IL-8 were significantly higher in metabolic syndrome patients as compared with those in the normal controls, while swimming intervention reduced HOMA-IR and these serum levels to different extents. Swimming intervention also promoted IRS-1 and Akt phosphorylation, and increased GLUT4 expression level. Thus, it is concluded that swimming intervention may improve metabolic syndrome through multiple pathways.

Project description:BACKGROUND:Metabolic syndrome (MetS) is an obesity-driven condition of pandemic proportions that increases the risk of type 2 diabetes and cardiovascular disease. Pathophysiological mechanisms are poorly understood, though inflammation has been implicated in MetS pathogenesis. The aim of this study was to assess the effects of galantamine, a centrally acting acetylcholinesterase inhibitor with antiinflammatory properties, on markers of inflammation implicated in insulin resistance and cardiovascular risk, and other metabolic and cardiovascular indices in subjects with MetS. METHODS:In this randomized, double-blind, placebo-controlled trial, subjects with MetS (30 per group) received oral galantamine 8 mg daily for 4 weeks, followed by 16 mg daily for 8 weeks or placebo. The primary outcome was inflammation assessed through plasma levels of cytokines and adipokines associated with MetS. Secondary endpoints included body weight, fat tissue depots, plasma glucose, insulin, homeostasis model assessment of insulin resistance (HOMA-IR), cholesterol (total, HDL, LDL), triglycerides, BP, heart rate, and heart rate variability (HRV). RESULTS:Galantamine resulted in lower plasma levels of proinflammatory molecules TNF (-2.57 pg/ml [95% CI -4.96 to -0.19]; P = 0.035) and leptin (-12.02 ng/ml [95% CI -17.71 to -6.33]; P < 0.0001), and higher levels of the antiinflammatory molecules adiponectin (2.71 ?g/ml [95% CI 1.93 to 3.49]; P < 0.0001) and IL-10 (1.32 pg/ml, [95% CI 0.29 to 2.38]; P = 0.002) as compared with placebo. Galantamine also significantly lowered plasma insulin and HOMA-IR values, and altered HRV. CONCLUSION:Low-dose galantamine alleviates inflammation and insulin resistance in MetS subjects. These findings support further study of galantamine in MetS therapy. TRIAL REGISTRATION:ClinicalTrials.gov, number NCT02283242.
