Objective. Previous studies have indicated that cigarette smokers are more likely to develop type 2 diabetes and that both smoking and type 2 diabetes are associated with C-reactive protein (CRP). This study examined whether CRP mediates the association between smoking quantity and type 2 diabetes.Methods. Nine hundred and eighty-four current Chinese smokers were selected from a community-based chronic disease survey conducted in Guangzhou and Zhuhai. Type 2 diabetes was defined according to the WHO 1999 criteria. CRP was measured with flow cytometry. Binary logistic regression was performed to assess the mediation.Results. A positive association was observed between smoking quantity and type 2 diabetes (P<0.05). After controlling for potential confounders, daily cigarette consumption was significantly associated with higher CRP levels. Current smokers with type 2 diabetes had higher CRP levels than smokers without type 2 diabetes. The association between the smoking quantity and type 2 diabetes was mediated by CRP, which accounted for 50.77% of the association.Conclusions. This study provides further evidence that smoking quantity is positively associated with type 2 diabetes and suggests that the association between smoking and type 2 diabetes might be mediated by CRP.

Diabetes mellitus is a group of metabolic diseases characterized by high blood glucose levels that result from defects in insulin secretion or action or both. Some recent studies had shown that elevated level of C?reactive protein (CRP) and uric acid are involved in the pathogenesis of type 2 diabetes, regardless of other characteristics of subjects. Our aim was to investigate the association between CRP and uric acid levels with diabetes in Bangladeshi population. Two hundred type 2 diabetic subjects (male 110, female 90) and 60 non diabetic subjects (30 male, 30 female) were included in the study over six months. CRP and uric acid were measured by Latex Agglutination method and enzymatic colorimetric method, respectively. CRP was significantly higher (p < 0.01) in diabetic compared to non-diabetic subjects for both male and female subjects. The level of uric acid was also significantly higher in male and female diabetic subjects (p < 0.05 and p < 0.01) compared to non-diabetic subjects, respectively. In multiple regression analysis, CRP showed a positive association with uric acid and BMI in both diabetic and non-diabetic subjects. On the other hand, uric acid showed positive association with fasting blood sugar (FBS), diastolic blood pressure, HbA1c and CRP in case of diabetic subjects, but with age, BMI, CRP, HbA1c and creatinine in non-diabetic subject. Uric acid also shows a significantly (p < 0.001) positive Pearson correlation with CRP. These data strongly suggest that compared to non-diabetic subjects, diabetic subjects have significantly higher level of CRP and uric acid.

Objective. To investigate whether the Glycemic Index (GI) or Glycemic Load (GL) of a diet is associated with C-reactive Protein (CRP) and risk of type 2 diabetes in a prospective study.Materials and Methods. Our analysis included 4,366 participants who did not have diabetes at baseline. During follow-up 456 diabetes cases were confirmed. Dietary GI and GL were derived from a food-frequency questionnaire and its association with CRP was examined cross-sectionally using linear regression models. The association of GI and GL with diabetes incidence was examined using Cox proportional hazard models.Results. GL, but not GI, was associated with lnCRP at baseline (bGL=0.11per 50 units;P=.01). When comparing the highest to the lowest tertile of GI with respect to diabetes incidence, a Relative Risk (RR) of 0.95 [95%CI 0.75, 1.21] was found after adjustment for lifestyle and nutritional factors. For GL the RR for diabetes incidence was 1.00 [95%CI 0.74, 1.36]. Additional adjustment for CRP did not change RRs.Conclusion. Since GI was not associated with CRP and risk of type 2 diabetes, it is unlikely that a high GI diet induces the previously shown positive association between CRP and risk of type 2 diabetes by increasing CRP concentrations.

Diabetes Mellitus is one of the most common major public health problems having worldwide distribution. Depending on the etiology of diabetes mellitus, factors contributing to hyperglycemia may include; reduced insulin secretion, decreased glucose usage and increased glucose production. Recently, there in increasing evidence that an ongoing cytokine induced acute phase response which is sometimes called low grade inflammation, but part of a widespread activation of the innate immune system, is closely involved in the pathogenesis of type 2 diabetes mellitus and associated complications such as dyslipidemia and atherosclerosis. Elevated circulatory inflammatory markers such as C-reactive protein and interleukin-6 predict the development of type 2 Diabetes mellitus and several drugs with anti-inflammatory properties both lower both acute phase reactants and glycemia and possible decrease the risk of developing type 2 diabetes mellitus. In this mini review article, we aimed to systematically review the role of C-reactive protein (CRP) as inflammatory marker with increased risk of type 2 diabetes as well the relation with type 1 diabetes

Purpose: Patients with Type 2 diabetes (T2D) have increased risk of depression and anxiety. Evidence suggests that a heightened inflammatory state may contribute to this association. Females experience more depression and higher inflammation levels than males. This study compared associations of serum high-sensitivity C-reactive protein (hs-CRP) levels with symptoms of depression and anxiety between men and women with Type 2 diabetes mellitus (T2DM). Method: Cross-sectional data including demographic and disease characteristics, symptoms of depression and anxiety, clinical data, and laboratory values were collected from 392 patients with T2DM recruited from a general hospital in Shandong Province, China. We evaluated associations between serum hs-CRP level and symptoms of depression and anxiety in males and females separately using multiple linear regressions and χ2 tests for trend. Results: Sex moderated the association between serum hs-CRP level and symptoms of depression ( B = .112 [ SE = 0.049]; p = .022) and anxiety ( B = .137 [ SE = 0.053]; p = .011). Among females, hs-CRP level was positively associated with depression ( B = .034, 95% confidence interval [CI] = [.006, .061]; p = .016, false discovery rate [FDR]-adjusted p = .020) and anxiety ( B = .041, 95% CI [.011, .071], p = .007, FDR-adjusted p = .007). Positive trends indicated a higher prevalence of clinically significant symptoms of depression and anxiety in higher serum hs-CRP categories in females. No associations were found in males. Conclusion: Findings demonstrate that associations between serum hs-CRP level and symptoms of depression and anxiety in patients with T2D are sex-specific, with only females demonstrating a significant positive association.

Results of numerous studies give definitive evidence that phenofibrate affects activity of PPAR-a receptors in liver and thereby decreases the level oflipids responsible for the development of atherosclerosis (VLDL, small dense LDL); simultaneously, it increases the level of anti-atherogenic HDL.Activation of PPAR-a receptors in vascular cells decreases activity of inflammation markers, such as C-reactive protein, TNF-a, IL-6, fibrinogen,etc. These effects of phenofibrate eventually lead to reduced risk of macro- and microvascular diabetic complications.
