Abstract

Background & Objectives: Adenosine plays a crucial role in bioactivity of insulin and regulates insulin activity in type 2 diabetes mellitus (T2DM). The aim of our study was to study the altered levels of adenosine deaminase and its association with insulin in T2DM.

Methods: The The preliminary case-control study included age, sex and body mass index (BMI) matched 68 T2DM cases and 52 healthy control subjects. Serum ADA was measured using a spectrophotometer while fasting serum levels of insulin was measured by commercially available immunoassay kits and routine biochemical parameters were analyzed in all study groups.

Results: Serum ADA level was found significantly higher among T2DM subjects with respect to controls (38.77 ± 14.29 versus 17.02 ± 5.74 U/L; P < 0.0001). An increase in serum insulin levels were also observed in T2DM cases as compared to controls and were statistically significant (17.28 ± 6.71 versus 10.33 ± 3.89 U/L; P < 0.0001).  Serum ADA level showed a significant positive correlation with fasting plasma glucose (r = 0.324; P = 0.007) level among non-obese T2DM subjects, but no significant correlation was observed in controls (r = 0.071; P = 0.615).

Conclusion: The high level of serum ADA suggests that it may be used as a prognostic marker for the pathogenesis of T2DM.

Keywords: Diabetes Mellitus, Adenosine deaminase, Insulin, Insulin resistance.
