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%CI1.026-4.942),P=0.043],
atherosclerosis[OR=2.726(95% CI1.953-3. 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.
