Abstract Introduction Chronic inflammation is associated with the development, progression and long-term complications of type 2 diabetes. Hyperglycemia is associated with chronic low-grade inflammation, and thus has become the focus of many screening and treatment recommendations. We hypothesize that insulin may also be associated with inflammation and may be an additional factor to consider in screening and treatment. Methods This study used National Health and Nutrition Examination Survey data from 2005 to 2010 to analyze the association between fasting insulin and C-reactive protein (CRP). A two-part model was used due to the high number of values reported as 0.1 mg/L. Two models were analyzed, both with and without the addition of waist circumference to other covariates in the model. Results The final sample included 4527 adults with a mean age of 43.31 years. In the first model, higher fasting insulin was associated with increased odds of CRP > 0.1 mg/L (OR = 1.02, p < .001) and with higher CRP (β = 0.03, p < .001). In the adjusted model, including waist circumference as a covariate, higher fasting insulin was not associated with CRP > 0.1 mg/L (OR = 1.00, p = .307) but the association between higher fasting insulin and higher continuous CRP remained significant (β = 0.01, p = .012). Conclusion This study found that higher fasting insulin is associated with higher CRP. These results suggest that treatment approaches that simultaneously decrease insulin levels as well as glucose levels may provide additive anti-inflammatory effects, and therefore may improve long-term outcomes for adults with type 2 diabetes.

It has been suggested that Type 2 diabetes may, in part, be precipitated or accelerated by an acute-phase reaction as part of the innate immune response, in which large amounts of cytokines are released from adipose tissue, creating a low-grade inflammatory milieu. There is also firm evidence that atherosclerosis is an immune-mediated inflammatory disease. Therefore it is reasonable to imply that low-grade inflammation is an important pathogenetic factor in atherosclerosis and cardiovascular events in patients with Type 2 diabetes. Over the last few years, there have been a lot of promising clinical markers proposed to link inflammation and atherosclerosis. Of these markers, hs-CRP (high-sensitivity C-reactive protein) might be a prognostic marker for further cardiovascular events, although this has been refuted recently. In this issue of Clinical Science, Castoldi and co-workers have demonstrated that, in patients with Type 2 diabetes categorized into low (<1.0 mg/l), medium (1.0–3.0 mg/l) and high (>3.0 mg/l) hs-CRP groups, serum levels of hs-CRP correlated with lipopolysaccharide-stimulated release of interleukin-1β and interleukin-6 in whole blood. This finding may indicate that low-grade inflammatory activity might influence cytokine production in these patients.

To study leukocyte telomere length and its relationship with metabolic profile 35 patients with metabolic syndrome and type 2 diabetes mellitus (T2DM) and 21 healthy people of middle age (35-59 years) were examined. The anthropometric characteristics of obesity, indicators of lipid and glucose metabolism, alanin aminotransferase (ALT) and high sensitive C-reactive protein levels were studied. The relative average telomere length was determined by the method of monochrome multiplex quantitative real time polymerase chain reaction. Patients with T2DM had higher BMI, waist circumference, higher high sensitive C-reactive protein, ALT and glucose levels and a worse lipid profile (p <0.05). At the same time, the median telomere length did not differ between groups. Nevertheless, in the T2DM group the telomere length inversely correlated with body weight (r = –0.35; p < 0.05), BMI (r = –0.36; p < 0.05), waist circumference (r = –0.34; p < 0.05) and ALT level (r = –0,44; p<0,05) in contrast to healthy subjects. No relationship was found between the telomere length and the level of fasting glycemia, as well as the age of the participants of both groups. Thus, in T2DM patients increase in BMI, waist circumference and ALT level were associated with a shorter leukocyte telomere length. Despite the worse metabolic profile, the telomere length in middle-aged T2DM patients did not differ from that in the control group. This indicates that the leukocyte telomere length is influenced not only by the presence of T2DM and the metabolic profile indicators, but, obviously, by other factors as well.

We investigated serum concentration of C-reactive protein (CRP) and measures of adiposity in 30 patients with type 2 diabetes mellitus (15 male, 15 female) and 30 age and sex-matched apparently healthy subjects.CRP concentration was determined by laser nephelometry (BN II Analyzer) and CardioPhase high-sensitivity CRP (DADE BEHRING) was used as reagent which consists of polystyrene particles coated with mouse monoclonal antibodies to CRP.Results have shown that serum CRP concentration in patients with type 2 diabetes mellitus was statistically significantly higher compared to control group of healthy subjects (p<0,05). Body mass index (BMI) correlated significantly with serum concentration of CRP in patients with type 2 diabetes mellitus (r=0,614; p<0,001). Statistically significant positive correlation was also found between waist to hip ratio and serum CRP concentration in patients with type 2 diabetes mellitus (r=0,426; p<0,05).Elevated serum CRP concentration in patients with type 2 diabetes mellitus is probably caused by the presence of chronic low-grade inflammation in these patients. It is possible that determined increase of CRP concentration reflects activation of innate immune system components in patients with type 2 diabetes mellitus. Implications of established association between measures of adiposity and serum CRP level in type 2 diabetes mellitus remain unclear.

To investigate effects of long-term testosterone (T) therapy in obese men with T deficiency (TD) and type 2 diabetes mellitus (T2DM), data were collected from two observational, prospective, and cumulative registry studies of 561 men with TD receiving T therapy for up to 6 years. A subgroup of obese hypogonadal men with T2DM was analyzed. Weight, height, waist circumference (WC), fasting blood glucose (FBG), glycated haemoglobin (HbA1c) blood pressure, lipid profile, C-reactive protein (CRP), and liver enzymes were measured. A total of 156 obese, diabetic men with T deficiency, aged 61.17 ± 6.18 years, fulfilled selection criteria. Subsequent to T therapy, WC decreased by 11.56 cm and weight declined by 17.49 kg (15.04%). Fasting glucose declined from 7.06 ± 1.74 to 5.59 ± 0.94 mmol/L (P<0.0001for all).HbA1cdecreased from 8.08 to 6.14%, with a mean change of 1.93%. Systolic and diastolic blood pressure, lipid profiles including total cholesterol: HDL ratio, CRP, and liver enzymes all improved (P<0.0001). Long-term T therapy for up to 6 years resulted in significant and sustained improvements in weight, T2DM, and other cardiometabolic risk factors in obese, diabetic men with TD and this therapy may play an important role in the management of obesity and diabetes (diabesity) in men with T deficiency.

Abstract Context: Elevated high-sensitivity C-reactive protein (hsCRP) levels have frequently been shown to be associated with type 2 diabetes (T2D); however, very little is known about this in Asian Indians, a high-risk group. Objective: The aim of the study was to assess the association of hsCRP with T2D and to determine its correlates in North Indians of Indo-European origin. Design and Patients: A cross-sectional population-based study of 2520 urban subjects, comprising 1410 T2D patients and 1110 nondiabetic subjects, was carried out and 18 metabolic traits were assessed. Results: Median hsCRP levels were significantly higher in both diabetic men and women as compared to their nondiabetic counterparts (P &lt; 0.0001). Elevated hsCRP was positively associated with T2D (odds ratio, 1.66; 95% confidence interval, 1.21–2.28; P = 0.002) even after adjusting for markers of obesity. After adjustments for age, sex, and BMI, HbA1c was the major correlate of hsCRP in nondiabetic subjects (β = 0.28; P = 0.03). We observed that T2D patients were at higher risk for cardiovascular disease compared to nondiabetic subjects when classified into low-, intermediate-, and high-risk groups based on hsCRP levels (ptrend = 3.8 ×10−15). Conclusions: We demonstrate the association of low-grade systemic inflammation, as indicated by elevated hsCRP levels, with T2D in North Indian population. This association was independent of obesity. Obesity and glycemic control were the major correlates of hsCRP levels. Future studies are required to evaluate the influence of modulators including genetic variations on the elevation of hsCRP levels in this population.
