INTRODUCTION: Diabetes mellitus is associated with a lot of changes in intermediary metabolism and several authors reported on higher frequency of liver diseases in patients with diabetes. AIM OF THE STUDY: Was to establish the changes of blood serum cholinesterase, prealbumin and albumin, parameters which are accepted as an index of liver proteosynthetic function, in patients with diabetes mellitus. PATIENTS AND
METHODS: The study group consisted of 207 patients with diabetes mellitus (83 patients with type I and 124 patients with type II diabetes mellitus). Control group consisted of 179 healthy subjects. The activity of cholinesterase was assayed by the kinetic method, concentrations of prealbumin and albumin were determined immunochemically.
RESULTS: Activity of serum cholinesterase was significantly higher in group of patients with diabetes mellitus than in control group (65.05 vs 73.33 microkat/l). The concentration of prealbumin was lower in blood serum of patients with diabetes than in controls (308.10 vs 285.85 mg/l). Serum levels of albumin were not different in both studied groups. After dividing of patients according to the type of diabetes, 80 % of abnormal values of cholinesterase and prealbumin were present in patients with type II diabetes.
CONCLUSIONS: The results of our study showed abnormal values of determined liver tests approximately in 22 % of patients with diabetes mellitus. The character of laboratory changes--increased activity of cholinesterase, decreased concentration of prealbumin and normal levels of albumin, suggests development of liver steatosis in these patients. The most of pathological findings were in patients with diabetes type II (Tab. 3, Ref. 20).
