Islet Inflammation

The pathology of islets from patients with Type 2 diabetes displays an inflammatory process characterized by the presence of immune cell infiltration, cytokines, apoptotic cells, amyloid deposits and, eventually, fibrosis. Indeed, analysis of β-cells from patients with Type 2 diabetes displays increased IL-1β (interleukin 1β) expression. Furthermore, increased islet-associated macrophages are observed in human Type 2 diabetic patients and in most animal models of diabetes. Importantly, increased numbers of macrophages are detectable very early in high-fat-fed mice islets, before the onset of diabetes. These immune cells are probably attracted by islet-derived chemokines, produced in response to metabolic stress, and under the control of IL-1β. It follows that modulation of intra-islet inflammatory mediators, particularly interleukin-1β, may prevent islet inflammation in Type 2 diabetes and therefore presents itself as a promising therapeutic approach.

Islet Inflammation

Onset of Type 2 diabetes occurs when the pancreatic β-cell fails to adapt to the increased insulin demand caused by insulin resistance. Morphological and therapeutic intervention studies have uncovered an inflammatory process in islets of patients with Type 2 diabetes characterized by the presence of cytokines, immune cells, β-cell apoptosis, amyloid deposits, and fibrosis. This insulitis is due to a pathological activation of the innate immune system by metabolic stress and governed by IL-1 signaling. We propose that this insulitis contributes to the decrease in β-cell mass and the impaired insulin secretion observed in patients with Type 2 diabetes.

The aim of the present study was to evaluate the effect of prolonged inhibition of β-oxidation on glucose and lipid muscle forearm metabolism and cGMP and endothelin-1 forearm release in patients with type 2 diabetes mellitus and ischemic cardiomyopathy. Fifteen patients were randomly allocated in a double-blind cross-over parallel study with trimetazidine (20 mg tid) or placebo lasting 15 days. At the end of each period, all patients underwent euglycemic hyperinsulinemic clamps with forearm indirect calorimetry and endothelial balance of vasodilator and vasoconstricor factors. Compared with placebo, trimetazidine induced 1) an increase in insulin-induced forearm glucose uptake and glucose oxidation accompained by a reduction in forearm lipid oxidation and citrate release and 2) a decrease of endothelin-1 release paralleled by a significant increase in forearm cGMP release. Forearm glucose oxidation significantly correlated with cGMP release ( r = 0.37, P < 0.04), whereas forearm lipid oxidation positively correlated with endothelin-1 release ( r = 0.40, P < 0.03). In conclusion, for the first time, we demonstrated that insulin-induced forearm glucose oxidation and forearm cGMP release were increased whereas forearm endothelin-1 release was decreased during trimetazidine treatment. Muscle's metabolic and vascular effects of trimetazidine add new interest in the use of trimetazidine in type 2 diabetic patients with cardiovascular disease.

Aims. This study aimed to investigate whether the change of plasma myeloperoxidase (MPO) level would be associated with the incidence of coronary artery disease (CAD) among diabetic patients.Methods. 339 patients with type 2 diabetes mellitus (DM) underwent coronary angiography. Of them, 204 cases had CAD and were assigned to CAD group and 135 cases without CAD were assigned to non-CAD group.Results. Compared to non-CAD group, CAD group had higher level of plasma MPO (p<0.01). Multiple linear regression analysis showed that plasma MPO level was correlated with Gensini score. Multiple logistic analysis showed that the odds ratios for CAD across increasing tertiles of MPO level were 1.191 (0.971–1.547) and 1.488 (1.115–2.228) (p=0.048,p=0.009versus 1st tertile of MPO level, resp.) by adjusting for age, sex, and other conventional risk factors for CAD. The subjects were stratified into nine groups according to tertiles of MPO and HbA1c. The odds ratio for CAD was significantly higher in group with highest levels of MPO and HbA1c (OR = 4.08,p<0.01).Conclusion. Plasma MPO level was positively correlated with the degree of coronary artery stenosis in type 2 diabetic patients, and increasing blood glucose might amplify the association between MPO and CAD.

Background. Offspring of type 2 diabetic patients are at a high risk of type 2 diabetes. Information on diabetes genetic susceptibility and prevention should be supplied to the offspring.Methods. A six-page booklet on diabetes genetic susceptibility and prevention was distributed to 173 patients who ere ordered to hand it to their offspring. The patients answered a self-administered questionnaire on booklet delivery and attitudinal and behavioral changes toward diabetes and its prevention in themselves and their offspring.Results. Valid responses were obtained from 130 patients. Forty-nine patients had actually handed the booklet. Booklet induces more relief than anxiety. From the patient's view, favorable attitudinal and/or behavioral changes occurred in more than half of the offspring who were delivered the booklet.Conclusion. The booklet worked effectively on attitudes and behaviors toward diabetes and its prevention both in patients and their offspring. However, the effectiveness of patients as information deliverers was limited.

BACKGROUND Type 2 diabetes mellitus is common in the Indian population and awareness regarding the disease and its complications is low among the patients with diabetes. There is lack of studies regarding awareness of complications of diabetes among type 2 diabetic patients. The purpose of this study was to assess the awareness of diabetic complications among type 2 diabetic patients. METHODS This is an institutional based observational study. The sample comprised of 150 adult patients with type 2 diabetes mellitus who underwent treatment in the Department of Medicine, Medical College Kottayam and the patient’s age ranged from 18 - 77 years. RESULTS Majority of patients were in the age group 38 to 57 and the sample comprised of 56 % males and 44 % female patients. Out of 150 patients involved in the study, 120 patients (80 %) were aware of the complications of diabetes mellitus. Among the male patients, 70 (83.33 %) and among females, 50 (75.75 %) were aware of the complications in diabetes. In the study sample, 92 (61.33 %) were aware of the foot problems, 120 patients (80 %) were aware of renal complications, 91 patients were aware regarding eye problems of diabetes, 38 (25.33 %) regarding development of hypertension, 62 (41.33 %) regarding heart attack, 42 (28 %) patients were aware regarding development of stroke and 78 patients (52 %) had awareness regarding occurrence of recurrent infections. CONCLUSIONS Awareness regarding diabetes and its complications is fairly good among the diabetic patients in Kerala. Awareness regarding all complications of diabetes was higher among males than females. Providing awareness to type 2 diabetic patients by various educational programs may be of further help to prevent complications and to decrease the mortality and morbidity in type 2 diabetes patients.

Fifty-four type 2 diabetic patients with neuroischemic foot ulcers were randomised to treatment with 5000 IU of dalteparin, (n=28), or physiological saline, (n=26), once daily until ulcer healing or for a maximum of 6 months. Thirty-three patients had normo-, 15 micro-, and 6 macroalbuminuria. The urinary levels of IgM and IgG2were elevated in 47 and 50 patients, respectively. Elevated urinary levels of IgM and IgG2indicate decreased glomerular size selectivity. Urine IgM levels were associated with IGF-1/IGFBP-1 and IGFBP-1 levels. Dalteparin treatment increased urinary levels of glycosaminoglycans (P<0.001) and serum IGFBP-1 (P<0.05) while no significant effects were seen in any of the other studied parameters. In conclusion, dalteparin therapy in patients with type 2 diabetes had no effects on urinary levels of albumin, IgM, or IgG2despite significantly increased glycosaminoglycans in urine. Elevated urinary levels of IgM and IgG2might be more sensitive markers of renal disease than albuminuria in patients with type 2 diabetes and antihypertensive therapy.

<p>In addition to known risk factors, the role of different micronutrients such as selenium in diabetes incidence has been proposed. Some previous studies have shown an association of selenium deficiency and type 2 diabetes mellitus, while other studies have not confirmed such a relationship. The aim of this study was to evaluate serum level of selenium in patients with Type 2 diabetes compared with the control group. This cross-sectional study was carried out on patients with type 2 diabetes in Zahedan, southeastern Iran. One hundred newly diagnosed type 2 diabetic patients were evaluated for serum selenium level. One hundred subjects from the general population who had normal fasting blood sugar levels were selected as the control group. The control group subjects were matched in pairs with each of patients on the basis of sex, age (± one year), and body mass index (±1). Serum level of selenium was determined by spectrometry method. Results were compared using t-test. The mean serum level of selenium in patients was 94.47±18.07 µg/L whereas in control group was 142.79±23.67 µg/L. The mean serum level of selenium was significantly different between the two groups (P&lt;0.001). Serum levels of selenium in diabetic patients with significant difference statistically were lower than the control group. In order to evaluate serum level of selenium in patients with diabetes, studies with larger sample size are required. Likewise, prospective studies along with selenium supplementation and investigating its effect on incidence of diabetes are accordingly needed.</p>

Objective — To investigate whether serum lipoprotein(a) [Lp(a)] is an independent risk factor for abnormal blood pressure in patients with type 2 diabetes mellitus. Method — Analyzed data collected from diabetes patients and epidemiological survey from January 1,2020 to May 01,2021, with hypertension as a dependent variable, metabolic index such as glycosylated hemoglobin, serum total cholesterol, serum triglyceride and Lp(a) were independent variables, established logistic regression equation, analyze the influence of their variables on dependent variables. Results — The OR value of Lp(a) is 1.020, 95% confidence intervals (1.006, 1.035), p 0.006; The OR value of age is 1.073, 95% confidence interval (1.028, 1.119); and OR of the remaining parameters were tested no statistically different, p>0.05. Conclusions — The abnormal elevated Lp(a) level in the serum of type 2 diabetic patients may be related to the occurrence of hypertension. For patients with high Lp(a), Monitoring blood pressure may help to better detect and diagnose hypertension. At the same time, it is suggested that reducing serum Lp(a) level may reduce the risk of hypertension.

Background: Microalbuminuria is one of the earliest markers of diabetic nephropathy, and if not recognized and treated early it may lead to diabetic nephropathy resulting in chronic renal failure. Aims and Objective: The aim of the current study was to find out the prevalence of microalbuminuria among newly detected Type 2 diabetic patients and also compare prevalence of microalbuminuria in patients with or without hypertension, dyslipidaemia and obesity. Materials and Methods: In this retrospective study, we analysed 90 patients with new onset type 2 diabetes mellitus. We divided the patients into two groups, group 1 with comorbidities like hypertension, dyslipidaemia and obesity (50 patients) and group 2 without comorbidities (40 patients). We analysed urinary microalbumin level in all patients and compared the prevalence of microalbuminuria between group 1 and group 2. Results: In our cohort of 90 patients, urinary microalbuminuria was found in 30 patients (33.3%). When we divided these nephropathy patients to group1 and group 2, we observed that group 1 with comorbidities had higher percentage of nephropathy patients i.e 24 out of 50(48%). Group 2 with 40 patients had only 6 patients with microalbiminuria ie 6 out of 40(15%). Incidence of microalbiminuria was higher in patients with hypertension, dyslipidaemia and obesity. Conclusions: We conclude that incidence of microalbiminuria is much more common in newly diagnosed type 2 diabetes. We also conclude that hypertension, obesity and hypercholesterolemia are risk factors for nephropathy and urinary microalbuminuria appears to be much more sensitive than serum creatinine as screening tool to detect diabetic nephropathy.
