Division of Medicine, Hadassah-Hebrew University Medical Center, Jerusalem, Israel.

A 69-year-old diabetic woman with diffuse atherosclerosis presented with acute renal failure due to contrast nephropathy and severe metformin-induced lactic acidosis. There was a discrepancy between the patient's elevated serum creatinine level, indicative of severe renal insufficiency, and her very low blood urea nitrogen content. It is postulated that the patient's extremely severe acidosis interfered with her hepatic urea generation, contributing to this unusual biochemical abnormality.

D008687 Metformin A biguanide hypoglycemic agent used in the treatment of non-insulin-dependent diabetes mellitus not responding to dietary modification. Metformin improves glycemic control by improving insulin sensitivity and decreasing intestinal absorption of glucose. (From Martindale, The Extra Pharmacopoeia, 30th ed, p289) Dimethylguanylguanidine,Dimethylbiguanidine,Glucophage,Metformin HCl,Metformin Hydrochloride,HCl, Metformin,Hydrochloride, Metformin
D001806 Blood Urea Nitrogen The urea concentration of the blood stated in terms of nitrogen content. Serum (plasma) urea nitrogen is approximately 12% higher than blood urea nitrogen concentration because of the greater protein content of red blood cells. Increases in blood or serum urea nitrogen are referred to as azotemia and may have prerenal, renal, or postrenal causes.

D003924 Diabetes Mellitus, Type 2 A subclass of DIABETES MELLITUS that is not INSULIN-responsive or dependent (NIDDM). It is characterized initially by INSULIN RESISTANCE and HYPERINSULINEMIA; and eventually by GLUCOSE INTOLERANCE; HYPERGLYCEMIA; and overt diabetes. Type II diabetes mellitus is no longer considered a disease exclusively found in adults. Patients seldom develop KETOSIS but often exhibit OBESITY.
