Abstract

Insulin resistance is a central feature of type 2 diabetes. Salicylates prevent lipid-induced insulin resistance in rodents by interrupting inflammatory pathways. We therefore investigated whether salicylates reduce lipid-induced insulin resistance in humans by affecting inflammatory pathways as reflected by serum adipocytokines. Ten healthy men were included in a crossover intervention study. Four euglycemic-hyperinsulinemic clamps were performed, one without pretreatment, one with prior 2-h lipid infusion, one after pretreatment with 4 g acetylsalicylic acid (ASA), and one with ASA pretreatment and prior lipid infusion. Lipid-induced insulin resistance was quantified by the euglycemic-hyperinsulinemic clamp technique running at least 2 h. Repeated-measures ANOVA on two factors was used for comparison, and results were Bonferroni adjusted for multiple measurements. ASA effects on serum adipocytokines were addressed by comparing the areas under the curves. Glucose infusion rate (M value) of the control clamp without pretreatment was 6.3 (+/- 0.6) mg/kg.min. ASA pretreatment did not change glucose infusion rates (P = 0.6). Lipid infusion significantly decreased the M value to 4.1 (+/- 0.6) mg/kg.min (P = 0.008). After ASA pretre...Continue Reading

Biomarkers for Type 2 Diabetes

Biomarkers can help understand chronic diseases and assist in risk prediction for prevention and early detection of diseases. Here is the latest research on biomarkers in type 2 diabetes, a disease in which the body is unable to produce or properly use insulin.
