His diabetes is well controlled on metformin, with fasting glucose concentrations between 110150 mgdl. His blood pressure on multiple office visits are between 115-13075-85 mmHg. Today his temperature is 98F 36.7 C, blood pressure is 12580 mmHg, pulse is 86min, and respirations are 15min. Labs are obtained with the following results:Hemoglobin A1c: 6.7Glucose: 120 mgdlCholesterol plasma: 190 mgdLUrine albumin: 60mg24hrWhich of the following treatments is effective in slowing the progression of the most likely cause of this patients abnormal albumin result?? A: No effective treatments, B: Enalapril, C: Metformin, D: Simvastatin, E: Aspirin,  <response>: This is a question about treating microalbuminuria in a patient with diabetes mellitus. The patient has well-controlled diabetes based on his HbA1c and fasting glucose levels. His blood pressure is also well-controlled. The abnormal lab result is a urine albumin level of 60 mg24 hr, which indicates microalbuminuria. Microalbuminuria in diabetes is caused by early diabetic nephropathy. The goal is to slow the progression of diabetic nephropathy to prevent overt proteinuria and eventual end stage renal disease. Of the answer choices, enalapril an ACE inhibitor has been shown to be effective in slowing the progression of diabetic nephropathy. Metformin controls blood glucose but does not affect progression of nephropathy. Simvastatin lowers cholesterol but does not affect nephropathy progression. Aspirin is used for cardiovascular disease prevention but not for nephropathy. There are effective treatments for early diabetic nephropathy.B: Enalapril
