Variation of serum monocyte chemoattractant protein-1 in patients with diabetes and metabolic syndrome

This study investigated the variation of serum monocyte chemoattractant protein-1 (MCP-1) in patients with both diabetes mellitus (DM) and metabolic syndrome (MS). Based on the International Diabetes Federation (IDF) diagnostic criteria, 93 patients enrolled in this study were divided into four groups: normal control (NC), simple DM, simple MS, and DM plus MS (DM-MS) groups. The main measures included height, weight, waist circumference (WC), hip circumference, blood pressure, fasting blood glucose, insulin resistance index (HOMA-IR), serum triglyceride (TG), HDL-ch, LDL-ch, and MCP-1. The results showed that the serum levels of MCP-1 in the DM-MS group were significantly increased as compared with those in the DM and MS groups (P<0.05), and the increase in the MCP-1 level in the DM group was much higher than in the MS group (P<0.05). The DM-MS group had the highest HOMA-IR levels, followed by MS, DM and NC groups (P<0.05). Correlation tests showed that the association of MCP-1 with age, HDL-ch, or LDL-ch was insignificant, whereas that of MCP-1 with body mass index (BMI), waist hip rate (WHR), WC, systolic blood pressure (SBP), diastolic blood pressure (DBP), TG, and HOMA-IR was significantly positive. It was concluded that circulating MCP-1 was substantially increased in patients with both DM and MS as compared with that in the patients with DM or MS alone, and the central obese state may contribute to a more vicious proinflammatory condition and insulin resistance in patients with diabetes.
