Objectives
The study aimed to compare the levels of anti-inflammatory interleukin-2 (IL-2) and proinflammatory interleukin-18 (IL-18) among newly diagnosed type 2 diabetes mellitus (T2DM) and nondiabetic volunteers, to predict their roles as markers in the diagnosis of newly diagnosed T2DM.
Methods
In the study, 60 subjects were enrolled (30 T2DM cases and 30 non-diabetic controls). Biochemical parameters such as fasting plasma glucose (FBS), glycated haemoglobin (HbA1c), high sensitivity C-reactive protein (hs-CRP) and lipid profile were estimated in auto-analyser. Serum IL-2 and IL-18 levels were assessed by enzyme-linked immune sorbent assay (ELISA).
Results
Significant differences were observed in the levels of interleukins among study groups. The median (95% confidence interval) of IL-2 in cases and controls were 8.55 (6.07–47.23) and 45.87 (12.81–145.4) (p=0.02). The median (95% CI) of IL-18 on the other hand in cases and controls were 691.6 (580.3–872.6) and 511.1 (452.6–557.5) (p=0.0014).
Conclusions
Our study is the first to correlate IL-2 and IL-18 in newly diagnosed T2DM patients. Findings from this study highlight the anti-inflammatory role of IL-2 and proinflammatory role of IL-18 in T2DM. ROC analysis helped predict their role as markers in T2DM diagnosis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
