Study of arginase activity in serum of patients with hypothyroidism and type 2 diabetes mellitus

Abstract

In L-arginine metabolizing pathways, arginase and nitric oxide synthase are regulated in a reciprocal manner. In recent years, nitric oxide has been proposed as a key player in hyperthyroidism. The importance of arginase in arginine control has not yet been studied in hypothyroidism. The goal of this study was to examine the activity of arginase in in type 2 diabetic patients with and without hypothyroidism. The two most popular endocrinopathies that exist in clinical practice are thyroid disease and diabetes mellitus DM. The thyroid hormones, on the other hand, control the metabolism of carbohydrates and the pancreas activity. The study group consisted of 120 subjects divided into four groups; the first group included 30 healthy control subjects, the second group included 30 patients with both hypothyroidism and type 2 DM, the third group included 30 patients with hypothyroidism without type 2 diabetes (T2DM) and the fourth group included 30 patients with T2DM without hypothyroidism. The concentration of fasting serum glucose (FSG), total cholesterol (TC), triglyceride (TG), high density lipoprotein (HDL), low density lipoprotein (LDL), very low-density lipoprotein (VLDL), triiodothyronine (T3), thyroxin (T4), thyroid-stimulating hormone (TSH) were determined.
