Study of Serum Adenosine Deaminase Level in Type 2 Diabetes Mellitus and its Correlation with Glycemic Control

Diabetes mellitus is a cluster of abnormal metabolic disorder having common features of hyperglycaemia with a state of increased free radical activity. Chronic hyperglycemic status favours auto-oxidation and the formation of advanced glycation end products. Adenosine deaminase (ADA) is considered as a good marker of cell mediated immunity. Increased ADA activity in diabetic individuals could be due to altered insulin related T-lymphocyte function. Hyperglycaemia is associated with increased level of (ADA), which is one of the factor which leads to increase oxidative stress level by generatingthe reactve oxygen species (ROS) leading to insulin resistance. In our study, ADA level was significantly high in controlled diabetes mellitus type 2 (group II with HbA1c < 7) and was much higher in uncontrolled diabetics (group III with HbA1c > 7) compared to healthy controls (group I). The present study was aimed to find the level of Serum (ADA) among the patients with type 2 diabetes mellitus through a case control study and correlation of Adenosine deaminase with glycemic control (HbA1c). Comparison of the parameters fasting plasma glucose (FPG), post prandial plasma glucose (PPPG) HbA1c, and ADA between the 3 groups were done using Student t test and was statistically significant. Pearson's coefficient correlation was done between ADA and HbA1c and a positive correlaion was seen that was also statistically significant. This indicates that ADA ses with the extent of severity of type 2 diabetes. Positive correlation of ADA with HbA1c provides the information that ADA can be considered to reflect the glycemic status of the individual.
