Lack of induction of serum gamma-glutamyltransferase in diabetes mellitus

Summary:Some authors have suggested that carbohydrates can induce hepatic microsomal enzymes, resulting in increased serum gamma-glutamyltransferase (GGT) in diabetes mellitus. Previously we demonstrated the lack of serum GGT increases in patients with acute diabetic crises. In this work we studied serum GGT activity, blood glucose levels and glycosylated hemoglobin levels (HB A1) in 35 patients with diabetes mellitus and 27 healthy volunteers. We did not see differences in the serum GGT activity among controlled (25.05 +/- 2.72 U/l) and uncontrolled (26.44 +/- 4.05 U/l) diabetics and the control group (22.51 +/- 2.95 U/l). Also, there was no significant correlation between serum GGT and HB A1 levels in diabetic patients (r = 0.279). We think that our observations may be relevant because they support the hypothesis that hyperglycemia does not act as an enzyme-inducing agent in chronically uncontrolled diabetics and, furthermore, they indicate that in the presence of abnormal serum GGT levels in diabetics it is necessary to investigate other associated diseases.
