Evaluation of Some Inflammatory Cytokines Levels as A Marker for Diabetes

From the different causes of death diabetes has an advanced rank in the first 10. So the aim of this study was to relate between some pro-inflammatory cytokines (TNF-α, IL-6, and TGF-β1) and infection with diabetes as biomarkers for infection. Forty male Wister albino Streptozotocin (STZ) induced diabetic rats were used as a model for estimation of the related cytokines. The animals were divided in two groups, the first group was given a placebo, whereas the second was given Streptozotocin at a single dose of 70 mg/kg body weight to induce diabetes mellitus. Each rat's blood glucose level was measured 72 hours later. Diabetes was successfully induced in rats with blood glucose levels greater than 300 mg/dl. After 7 days, all groups were sacrificed and immunological responses, tumor necrosis factor-alpha (TNF-α), interleukin (IL-6), and transforming growth factor (TGF-β1) were measured. Glucose levels were shown to be significantly higher in the group that was given Streptozotocin at a single dose of 70 mg/kg body weight, with a percent change of 217.5% when compared to the control group. While in the diabetic group, there was also a large increase in IL-6, TNF-α and TGF-β1 levels, with a percent change of 82.24%, 77.7% and 74.5% respectively. From these results we can recommend these cytokines as a biomarkers for diabetes mellitus disease.
