The Ratios of Triglycerides and C-reactive protein to High density-lipoprotein -cholesterol as valid biochemical markers of the Nascent Metabolic Syndrome

Abstract

Aims: Metabolic syndrome (MetS), a cardiometabolic cluster, is a major global problem. The ratio of triglycerides (TG) to high-density lipoprotein cholesterol (HDL-C) is a good biomarker of MetS in certain populations C-reactive protein (CRP) has also been also shown to be a biomarker of MetS. Since CRP captures inflammation, we compared the ratios of TG to HDL-C and CRP to HDL-C in patients with nascent MetS. Methods: Patients with MetS (n = 58) and matched controls (n = 44) were recruited. Fasting blood samples were obtained for routine laboratories, insulin, and adipokines. TG and CRP ratios to HDL-C were calculated. Data were analyzed statistically. Results: Both the TG to HDL-C and CRP to HDL-C ratios were significantly increased in MetS and both increased with increasing severity of MetS. Whilst both correlated with cardiometabolic features and insulin resistance, only the CRP to HDL-C ratio correlated significantly with adiponectin and leptin. Receiver operating characteristic curve analysis showed that both ratios showed excellent discrimination for MetS with no significant differences between ratios. Conclusions: Thus both the TG to HDL-C and CRP to HDL-C ratios are significantly increased in patients with nascent MetS and appear to be valid biomarkers of MetS. However, these preliminary findings with CRP: HDL-C need confirmation in large prospective studies and could have important implications for assessing cardiometabolic risk in African Americans, an under-served population.
