Abstract Background Prediabetes is characterized by a hemoglobin A1c of 5.7–6.4% and fasting blood glucose of 100–125 mg/dl. A high percentage of prediabetes subjects develop type 2 diabetes mellitus in the next years. The effects of opioid peptides and their receptors, in addition to immunological cytokines, on prediabetes are not well understood. Therefore, molecular, physiological, and clinical studies are required to link the opioid system, immune system, and insulin resistance (IR) in prediabetes. We hypothesize that opioid peptides (endomorphin-2 (EM2), and β-endorphin (βEP)), and their receptors (µ-opioid receptors (MOR) and κ-opioid receptors (KOR)), in addition to the inflammatory cytokines (IL-6) and anti-inflammatory cytokine (IL-10), affect IR parameters in patients with prediabetes. Methods Sixty prediabetes patients with IR (prediabetes+IR) and sixty prediabetes patients without IR (prediabetes-IR), in addition to 58 controls, have participated in the study. IL-6, IL-10, EM2, βEP, MOR, and KOR were measured by the ELISA technique. Results In general, most prediabetes subjects have dyslipidemia. The IL-6, IL-10, β-endorphin, MOR, and endomorphin-2 were higher in the prediabetes subgroups than the control group. The immune system was activated in the prediabetes in an IR-dependent manner. Prediabetes+IR can be predicted by the increased levels of IL-10, βEP, and EM2 and by the combination of IL-10 and EM2/KOR with good sensitivity and specificity. Conclusion Opioid peptides and their receptors were upregulated in patients with prediabetes, depending on the significance of IR and the immune cytokines. The intercorrelation between the immune system, EOS, and insulin in prediabetes was confirmed.

AbstractBackgroundPrediabetes is characterized by a hemoglobin A1c of 5.7%–6.4% and fasting blood glucose of 100–125 mg/dl. A high percentage of prediabetes subjects develops into type 2 diabetes mellitus in the following years. The effect of opioid peptides and their receptors, in addition to immunological cytokines on prediabetes, is not well understood.ObjectiveWe hypothesize that opioid peptides and their receptors affect the insulin and the insulin resistance (IR) in patients with prediabetes and that the immune cytokines, IL-6 (inflammatory factor) and IL-10 (anti-inflammatory factor), influence the opioid system.MethodsA total of 60 patients with prediabetes and IR (prediabetes+IR), 60 patients with prediabetes without IR (prediabetes-IR), and 60 controls participated in the study. The IR state was HOMAIR > 2.5. The enzyme linked immunosorbent assay was used to measure interleukin (IL)-6, IL-10, μ- and κ-opioid receptors (MOR and KOR), endomorphin-2 (EM2), and β- endorphin (βEP).ResultsThe subjects with prediabetes had dyslipidemia, and not all of them underwent the IR state. The IL-6, IL-10, β-endorphin, MOR, and endomorphin-2 were higher in the prediabetes subgroups compared with the control group. MOR was correlated with IL-10 and KOR. Prediabetes+IR can be predicted by the increased levels of the combination of IL-10, βEP, and EM2 and by the combination of IL-10 and endomorphin-2/KOR with good sensitivity and specificity.ConclusionOpioid peptides and their receptors were upregulated in patients with prediabetes depending on the significance of IR. These changes in the opioid system depend on the immune cytokines. Both systems need to be normalized to prevent further development into diabetes mellitus.

Prediabetes is a glucose homeostasis condition characterized by decreased absorption to glucose or reduced fasting glucose. Both of these are reversible stages of intermediate hyperglycaemia providing an increased type II DM risk. Pre-diabetes can therefore be viewed as a significant reversible stage which could lead to type II DM, and early detection of prediabetes may contribute to type II DM prevention. Prediabetes patients are at high risk for potential type II diabetes, and 70 percent of them appear to develop Type II diabetes within 10 years. The present study includes total 200 subjects that include 100 Prediabetic patients, 50 T2DM patients and 50 healthy individual. Blood samples were collected from the subjects were obtained for FBS, PPBS, Uric acid and Creatinine estimation, from OPD and General Medicine Wards. Present study showed low levels of Serum Uric Acid in prediabetic and T2DM patients were decreased as compared to control group, while the level of creatinine in prediabetic and diabetic were elevated as compared to control group, were not statically significant. Serum Uric Acid was high in control group and low in prediabetic and diabetic patients. Serum creatinine was declined in control group and increased in prediabetic and diabetic patients with increasing Fasting blood glucose level.

Objective To investigate the effect of electroacupuncture (EA) on endothelial dysfunction related to high fat diet (HFD)-induced insulin resistance through the phosphatidylinositol 3-kinase (PI3K)-protein kinase B (Akt) signalling pathway. Methods Twenty-four male Sprague-Dawley rats were fed a regular diet (Control group, n=8) or a HFD (n=16) for 12 weeks to induce an insulin resistance model. HFD-fed rats were divided into two groups that remained untreated (HFD group, n=8) or received electroacupuncture (HFD+EA group, n=8). EA was applied at PC6, ST36, SP6 and BL23. At the end of the experiment, fasting blood glucose (FBG), serum insulin (FINS), serum C-peptide (C-P) and homeostatic model assessment of insulin resistance (HOMA-IR) indices were determined. Pancreatic islet samples were subjected to histopathological examination. The thoracic aorta was immunostained with anti-rat insulin receptor substrate (IRS)-1, Akt and endothelial nitric oxide synthase (eNOS) antibodies. mRNA and protein expression of IRS-1, PI3K, Akt2 and eNOS in the vascular endothelium were determined by real-time PCR and Western blot analysis, respectively. Results The bodyweight increase of the HFD+EA group was smaller than that of the untreated HFD group. Compared with the HFD group, the levels of FBG, FINS, C-P and HOMA-IR in the HFD+EA group decreased significantly (P<0.01). Histopathological evaluation indicated that EA improved pancreatic islet inflammation. The expression of endothelial markers, such as IRS-1, PI3K, Akt2 and eNOS, decreased in the HFD group, while EA treatment appeared to ameliorate the negative impact of diet. Conclusion EA may improve insulin resistance and attenuate endothelial dysfunction, and therefore could play a potential role in the prevention or treatment of diabetic complications and cardiovascular disease through the PI3K/Akt signalling pathway.

Abstract Background: Asprosin, a newly identified adipokine, is pathologically increased in individuals with insulin resistance. However, the available evidence on the association of asprosin and type 2 diabetes mellitus (T2DM) status is still scarce. Therefore, this study aimed to determine the relationship between serum concentrations of asprosin and T2DM status . Methods: This observational study was performed based on 194 adults (97 newly diagnosed T2DM and 97 healthy individuals). Anthropometric and biochemical variables were determined in all participants . Serum concentrations of asprosin were measured using enzyme-linked immunosorbent assay (ELISA). Results: In patients with T2DM, the serum concentrations of asprosin were significantly higher than the healthy controls (4.18 [IQR: 4.4] vs. 3.5 [IQR: 1.85], P< 0.001). The concentrations of asprosin were significantly correlated with body mass index (BMI) and fasting blood glucose (FBG) in healthy subjects and with BMI, FBG, hemoglobin A1c (HbA1c), homeostatic model assessment of insulin resistance (HOMA-IR), and quantitative insulin check index (QUICKI), triacylglycerol (TAG) and total cholesterol/ high-density lipoprotein cholesterol (TC/HDL-C) ratio in the T2DM group. In fully adjusted model, the odds ratio (OR) of T2DM with serum concentrations of asprosin was approximately 1.547 (95% CI 1.293-1.850, P< 0.001) compared to the control group . Multiple stepwise regression analysis indicated that FBG and HOMA-IR were independently associated with asprosin in T2DM. Conclusion : Our findings indicated that serum concentrations of asprosin are increased in patients with T2DM. Also, asprosin is correlated with insulin resistance and TC/HDL-C ratio (atherosclerotic risk factor of cardiovascular diseases) in patients with T2DM.

BACKGROUND: Obesity is considered associated with an increase of resistin levels that plays a role in the regulation of energy and maintaining fasting blood glucose. Polymorphism of resistin is thought to be correlated with the levels of resistin and insulin resistance.AIM: This study aimed to examine the association of +299G > A and -420C > G resistin (RETN) gene with resistin level and insulin resistance in obese people of Indonesia.METHODS: We examined 142 healthy unrelated subjects consisting of 71 obese and 71 controls. Fasting blood glucose was measured by the enzymatic method while the resistin and insulin levels were measured by Elisa method. Insulin resistance was calculated by HOMA-IR index. Polymorphisms of RETN genes were examined by the Polymerase Chain Reaction-Restriction Fragment Length Polymorphism (PCR-RFLP) method, and the data was tested. The data were correlated with Kruskal Wallis continue logistic regression and simple linear regressionRESULTS: In the obese group, there was an increased level of insulin (17.74 vs 11.27 mU/L) and insulin resistance (HOMA-IR 3.9 vs 1.46) compared to the control group. Polymorphism of +299G > A was associated with insulin resistance (GA and GA + AA genotype significantly different compare GG genotype with P < 0.001). Resistin level was negatively correlated with insulin level (P = 0.017). CONCLUSION: In this study, polymorphism of +299G > A was identified as a risk factor for insulin resistance, and there was a significant association of serum resistin level with insulin level in the population of Indonesia.

Abstract Background: The development of sepsis, the low efficacy of antibiotics used, long-term antibiotic use, and the development of resistance to antibiotics are significant problems in patients in intensive care units. The use of biological markers is promising for the diagnosis and treatment of sepsis. In this study, proinflammatory cytokines, procalcitonin and four miRNA expressions were analyzed in a time-dependent manner in a patient group and control group, and the correlations between them were examined.Material and Method: The study included 30 patients in the intensive care unit who were diagnosed with sepsis and applied with SOFA and APACHE-2 scoring and 30 control subjects. Serum samples were taken at 24 hours, 72 hours, and on the 7th day. Analyses according to time were made of interleukin-1 beta, interleukin-6, interleukin-10, TNF-alpha, procalcitonin and four miRNAs (miR-122, miR-146a, miR-150, and miR-223) in the collected samples and comparisons were made between the patients and the control group. Results: At 24 hours, a decrease was observed in the miRNA-146a, miRNA-150, and miRNA-122 values and an increase in the miRNA-223 values in the sepsis group compared to the control group. At 72 hours, a decrease was observed in the miRNA-146a, miRNA-150, miRNA-122, and miRNA-223 values in the sepsis group compared to the control group.Conclusion: When procalcitonin and inflammatory cytokines were compared with selected miRNAs in the diagnosis, treatment follow-up, and prognosis of sepsis in the intensive care unit, a correlation between procalcitonin levels, proinflammatory cytokines and miRNA-150, miRNA-146a, and miRNA-223 was found.

Obesity is often correlated with insulin resistance and diabetes. Obese people need to consume high fiber, high protein, low fat, and/or low calories food. In this report, the effect of the consumption of jelly containing porang glucomannan and inulin along with a low-calorie diet on the development of insulin resistance and fasting blood glucose (FBG) in obese adults were studied. A total of fifty-five volunteers of both sexes, aged 21 to 35 , were randomized to 3 groups: treatment 2 years, and body mass index (BMI) ≥23 kg/m group, placebo group, and control group (not given any jelly). All participants should consume 1500 kcal daily for the first 4 weeks and 1200 kcal/day for the next 4 weeks, including 2 cups of jelly (120 g per cup) per day. Jelly with porang glucomannan and inulin maintain a normal level of insulin resistance index of individuals with normal FBG and significantly suppress insulin resistance development in individuals with FBG above normal baseline. These results significantly correlate with the intake of fiber. The FBG was maintained under normal conditions in individuals with normal baseline and improved from diabetes to prediabetes category in individuals with above normal baseline.

Abstract Background study of chemerin level in polycystic ovarian syndrome (PCO) patients and its relation to insulin resistance (IR). Upon chemerin on adipose tissue and glucose metabolism, serum chemerin has been recently studied in (PCO) women Aim We aimed to study the level of serum chemerin in PCO patients and its relation to insulin resistance. Methods The current study included 45 subjects with PCO syndrome and 45 healthy subjects as a control group. PCO subjects were divided into 27 obese PCO and 18 lean PCO. Control women were divided into 25 obese women and 20 lean women. Measurement of serum chemerin levels, fasting blood glucose (FBG),fasting insulin (FIN), total testosterone and pelvic ultrasonography Results Serum chemerin was significantly higher in the obese PCOS group (99.65 ± 13.72 ng/mL) compared with lean PCOS (87.99 ± 5,64 ng/mL) and the obese (76.82 ± 2.39 ng/mL) and non-obese (69.19 ± 8.40 ng/mL) control groups. In PCOS women, serum chemerin levels were positively correlated with Body mass index (BMI) (r = 0.835, P &lt; 0.001), Fasting blood glucose (FBG) (r = 0.493, P &lt; 0.005), Fasting insulin (FIN) (r = 0.913, P &lt; 0.001), Homeostasis model assessment of insulin resistance (HOMA-IR) (r = 0.9181, P &lt; 0.001). Conclusion There is an increase in serum chemerin level in PCOS patients with even more significant increase in patients with obese PCOS.

Despite long term antiretroviral therapy (ART), insulin resistance (IR) is common among people living with HIV/AIDS (PLWHA) exposing this population to a greater risk of cardiometabolic complications when compared to their uninfected counterparts. We previously identified an expansion in monocyte subpopulations in blood that were linked to the degree of IR in persons with HIV on stable ART. In this study, we directly assessed monocyte inflammatory functional properties from PLWHA on ART (n = 33) and HIV-uninfected controls (n = 14) of similar age, gender, and cardiovascular disease risk and determined the relationship with IR (homeostatic model assessment-insulin resistance (HOMA-IR)), calculated from fasting blood glucose and insulin measurements. Peripheral blood mononuclear cells were stimulated with oxidized low-density lipoproteins (oxLDL) and polyfunctional monocyte cytokine responses (IL-1β, IL-6, IL-8, or TNF-α) were determined by flow cytometry. Higher monocyte IL-1β and IL-8 responses to oxLDL were associated with higher IR in PLWHA but not in the control group. We observed that higher basal monocyte cytokine responses were associated with both duration since HIV diagnosis and ART initiation. In the management of IR in chronic HIV, strategies lowering monocyte IL-1β and IL-8 responses should be considered in addition to ART in order to limit adverse cardio-metabolic outcomes.

Short-chain fructo-oligosaccharides (FOS) are known to have beneficial effects on health. However, the effects of FOS on insulin resistance have not been fully clarified. We observed the effects of FOS feeding on insulin sensitivity and adipocytokine release from abdominal adipocytes in weaning rats. Male Sprague–Dawley rats, 3 weeks old, were divided into three groups and fed a sucrose-based American Institute of Nutrition (AIN)-93 growth diet (control), the control diet containing 5 % FOS for 5 weeks (FOS-5wk) or the control diet for 2 weeks followed by the 5 % FOS diet for 3 weeks (FOS-3wk). Tail blood was collected after fasting for 9 h on day 33 of feeding, and glucose and insulin levels were measured. On the last day, rats were anaesthetised and killed after the collection of aortic blood. Small- and large-intestinal mesenteric fat tissues were immediately excised, and the release of adiponectin, leptin and TNF-α was evaluated from the subsequently isolated adipocytes. The weight of the large-intestinal mesenteric fat, fasting blood insulin level and homeostatic model assessment for insulin resistance decreased in a time-dependent manner, and were much lower in the FOS-5wk group than in the control group. These values were correlated with aortic blood leptin levels. The secretion rate of leptin from the isolated mesenteric adipocytes in the small intestine, but not in the large intestine, was lower in the FOS-fed groups than in the control group. In conclusion, FOS feeding improved insulin sensitivity accompanied by the reduction in large-intestinal fat mass and leptin secretion from the mesenteric adipocytes of the small intestine.
