Serum Levels of Adenosine Deaminase and Insulin in Type 2 Diabetes Mellitus

Abstract

Aim: To estimate the levels of serum adenosine deaminase and insulin in patients with type 2 diabetes mellitus and healthy subjects and to find the correlation between serum adenosine deaminase and serum insulin in type 2 diabetes mellitus. Study Design: Case-control study. Place and Duration of the Study: Department of Biochemistry and Department of Medicine, Regional Institute of Medical Sciences (RIMS), Imphal, Manipur between October 2017 to September 2019. Methodology: 40 cases of type 2 diabetes mellitus were recruited from the Medicine Outpatient Department, RIMS and 40 healthy controls of age and sex-matched were recruited from those who came for a routine health check-up. Serum adenosine deaminase was measured by the calorimetry method and serum insulin was measured by ELISA method. The data were analyzed using statistical tools like Chi-square test, Independent sample t-test, Pearson’s Correlation through SPSS 21.0. Results: Mean serum adenosine deaminase was (38.97±8.853)U/L in cases and (20.05±5.309)U/L in controls and it was statistically significant (P<0.001). Mean serum insulin in cases was found to be (18.09±5.554) μIU whereas in controls, it was (9.06±2.509) μIU which is statistically significant (p<0.001). Serum adenosine deaminase and insulin were found to be positively correlated to each other (r= 0.956, p<0.001). Conclusion: Serum adenosine deaminase and serum insulin were significantly increased in type 2 diabetes mellitus and positively correlated to each other. Serum adenosine deaminase may be used as a prognostic marker for the pathogenesis of type 2 diabetes mellitus.
