High detective rate of"metabolic inflammatory syndrome"in patients with type 2 diabetes

Abstract

Objective Metabolites produced by metabolic imbalance such as free fatty acids and lipopolysaccharides can result in a state of chronic low-grade inflammation, or metabolic inflammation, which plays an important role in the pathogenesis of atherosclerosis, type 2 diabetes, non-alcoholic fatty liver disease, and obesity. The above metabolic disorders are closely related with the metabolic inflammation, which always coexist. Therefore, we proposed the concept ofmetabolic inflammatory syndrome(MIS). According to our study, patients with two or more metabolic disorders above could be diagnosed as MIS. The current research is aimed to investigate the prevalence of MIS and its components, and to compare the clinical values of MIS and metabolic syndrome(MS). Methods 2 001 in patients with type 2 diabetes from 6 hospitals in Shanghai were recruited in the current multi-center cross-sectional study. The diagnostic rates of MIS and MS and their components of both syndromes were compared. Results In the patients with type 2 diabetes, the detective rate of MIS was 96.2%, which was higher than that of MS(71.3%). Among 4 components of MIS, atherosclerosis showed the highest detective rate(75.6%). MIS[OR=2.252(95%CI 1.026-4.942), P=0.043], atherosclerosis[OR=2.726(95%CI 1.953-3.804), P<0.001], and MS[OR=1.915(95%CI 1.444-2.540), P<0.01] were the risk factors of coronary heart disease. Conclusion With atherosclerosis, type 2 diabetes mellitus, non-alcoholic fatty liver disease, and obesity as its 4 components, MIS has a high detective rate in patients with metabolic disorders, and seems to be more sensitive than MS to distinguish inflammation-related metabolic diseases. The concept of MIS will promote the screening and prevention of atherosclerosis in its early stage.
