Context: Chemerin is one of the adipokines that regulate fat metabolism. High-sensitivity C-reactive protein (hs-CRP) may be considered as a cardiovascular risk predictor. Measuring intima-media thickness of the CCA (C-IMT) is a well-evidenced tool for the detection of early stages of atherosclerosis. We aimed here to study both serum chemerin and hs-CRP as markers of subclinical atherosclerosis in Egyptian patients with type 2 diabetes, who are angiographically free of coronary artery disease (CAD). Subjects and methods: This cross-sectional study was conducted on 180 subjects divided into two groups: Group A included 90 type 2 diabetic patients without CAD and group B including 90 nondiabetic control subjects. All study subjects were having normal coronary angiography. Serum chemerin, homeostasis model assessment for insulin resistance (HOMA-IR), glycated haemoglobin (HbA1c), lipid profile, hs-CRP as well as C-IMT were assessed in all study subjects. Results: There was a statistically significant difference between the 2 groups regarding serum chemerin level, HOMA-IR, hs-CRP and C-IMT; being higher in the diabetic patients than in the control group (p = 0.006, 0.024, 0.040 and <0.001, respectively). There was positive correlation between serum chemerin level and waist-to-hip ratio (WHR), HOMA-IR, hs-CRP and C-IMT. Carotid intima-media thickness was positively correlated with patients' WHR, blood pressure, HbA1c, diabetes duration as well as hs-CRP, and negatively correlated with ankle-brachial index (ABI). Linear regression analysis showed that HbA1c, serum chemerin and hs-CRP were independently affecting C-IMT. Serum hs-CRP was positively correlated with HbA1c and HOMA-IR (p = 0.006 and 0.032, respectively), and negatively correlated with HDL-cholesterol level (p = 0.018). Conclusion: Both serum chemerin and hs-CRP could be considered as markers of subclinical atherosclerosis, and hence, may be utilized for the early detection of macrovascular disease, in Egyptian patients with type 2 diabetes.

Background. Diabetes mellitus is a pandemic disease. Type 2 diabetes (T2DM) is the most common type. Diabetic retinopathy (DR) and diabetic kidney disease (DKD) are disabling chronic complications. The relation between both is not yet well-established in T2DM. Egypt is considered one of the top ten countries regarding the prevalence of diabetes that makes diabetes and its complications a major health problem. This encouraged us to conduct this research. Materials and methods. The study included 79 patients with T2DM divided into two groups according to the presence of retinopathy. Both groups were subdivided according to urinary albumin to creatinine ratio (UACR) into normoalbuminuric and albuminuric subgroups. Retinopathy group was further subdivided according to severity of retinopathy into mild, moderate and severe non-proliferative DR (NPDR). Statistical analysis was done and relation between the severity of retinopathy and UACR was studied. Results. Patients with retinopathy had significantly higher diabetes duration and UACR than non retinopathy group. Also in subgroups of normoalbuminuria and albuminuria, retinopathy group was significantly higher regarding the same parameters. On subdividing the retinopathy group according to severity, severe NPDR group had significantly higher UACR. The severity of DR was significantly positively correlated with UACR. Conclusions. The present study identified a significantly positive correlation between early stages of DR and UACR in patients with T2DM in Egypt. Not all cases of DR had DKD especially in early stages and also not all cases of DKD are associated with the presence of DR

Introduction: Among macrovascular diabetes complications, CAD has been associated with diabetes in numerous studies beginning with the Framingham study. Many recent studies have shown that the risk of myocardial infarction (MI) in people with diabetes is equivalent to the risk in non-
