Abstract
The association of serum high-sensitivity C-reactive protein and ferritin with diabetes microvascular complications has not been examined concurrently in people with type 2 diabetes. So, we carried out this study in order to investigate this association in a group of type 2 diabetic patients. In a prospective cross-sectional study, 242 people with type 2 diabetes were enrolled. All of the participants were evaluated for diabetes microvascular complications. Retinal status was evaluated by retinal color photography and indirect ophthalmoscopy exam with dilated pupils. Michigan neuropathy screening instrument was used for detection of peripheral neuropathy, and albumin/creatinine ratio in a spot urine sample was considered to diagnose diabetic nephropathy. High-sensitivity C-reactive protein and ferritin were measured as indicators of acute phase proteins. The mean for high-sensitivity C-reactive protein was 5.3 ± 13.02 mg/L, and for ferritin was 126.9 ± 114.4 ng/mL. Statistically significant difference was found between the high-sensitivity C-reactive protein levels and diabetic nephropathy. Spearman’s correlation coefficients test revealed that high-sensitivity C-reactive protein was positively correlated with diabetic nephropathy (P = 0.05, r = 0.14). However, such a correlation was not found for diabetic neuropathy and retinopathy. Using binary logistic regression analysis, a significant odds ratio was defined for nephropathy and high-sensitivity C-reactive protein level (OR = 2.62; CI = 1.13–6.06; P = 0.025). Our findings suggest that low-grade inflammation is an independent predictor of diabetic nephropathy and measurement of high-sensitivity C-reactive protein can be useful for early detection of high-risk individuals.
