Association of C-reactive Protein with Early-stage Carotid Atherosclerosis in Japanese Patients with Early-state Type 2 Diabetes Mellitus

The aim of this study was to assess the association between high sensitivity-C-reactive protein (hs-CRP), a sensitive marker of inflammation, and early-stage carotid atherosclerosis, in patients with early-state type 2 diabetes mellitus. The study subjects were 75 patients with type 2 diabetes mellitus without obvious diabetic vascular complications, who were not on any medication, and whose HbA_(1c) level was less than 6.5%. We evaluated the mean intima-media thickness (IMT) of the common carotid artery (CCA) by ultrasound B-mode imaging. Then, we investigated various factors associated with CCA-IMT including hs-CRP. Serum hs-CRP levels correlated well with factors strongly associated with insulin resistance such as homeostasis model assessment of insulin resistance (HOMA-IR), fasting insulin level, and body mass index. Serum hs-CRP also correlated with mean CCA-IMT and serum levels of soluble intercellular adhesion molecule-1. Multivariate regression analysis using mean CCA-IMT as the dependent variable identified only age, hs-CRP, and diastolic blood pressure as independent determinants of mean CCA-IMT. While hs-CRP associates with insulin resistance and subclinical atherosclerosis in ealy-state type 2 diabetes, our data suggest that hs-CRP is a useful marker of subclinical atherosclerosis in early-state type 2 diabetes mellitus independent of factors that directly reflect insulin resistance.
