| Abstract: | Presence of oxidative stress in type 2 diabetes mellitus (DM) is well proved. Current study was undertaken to know the relation
between fasting plasma glucose (FPG) and copper along with antioxidants like total thiols and ceruloplasmin, and antioxidant
enzyme glutathione S transferase (GST). The study group consisted of a total of 201 subjects which included nondiabetic healthy
control subjects (n = 78) and diabetic patients (n = 123). Plasma total thiols, GST, copper and ceruloplasmin levels were
measured all the subjects using spectrophotometric methods and FPG levels were determined in clinical chemistry analyzer Hitachi
912. There was significant increase in FPG (P<0.001) and copper (P<0.001) and decrease in ceruloplasmin (P<0.001) and protein
thiols (P<0.001) in type 2 DM cases compared to healthy controls. There was no significant change in GST between type 2 DM
cases and controls. There was significant negative correlation of FPG with antioxidants like ceruloplasmin (r = −0.420, P<0.001)
and total thiols (r = −0.565, P<0.001). Protein thiols correlated positively with ceruloplasmin (r = 0.364, P<0.001). Our
study indicates possible increase in copper mediated generation of ROS leading to increased consumption of available antioxidants
in the body. |
