Stage IV Chronic Kidney Disease

A 54-year-old woman with type 2 diabetes presents for care. Her creatinine level has increased from 1.1 mg per deciliter (97 μmol per liter) 4 years ago to 3.1 mg per deciliter (274 μmol per liter) at the most recent measurement (estimated glomerular filtration rate, 26 ml per minute per 1.73 m2 of body-surface area). Her urinary protein excretion is 2.8 g per 24 hours. Her blood pressure is 155/90 mm Hg, and the glycated hemoglobin level is 7.6 mg per deciliter. Her current medications include an oral hypoglycemic agent, an angiotensin-converting–enzyme inhibitor, a statin, and a thiazide diuretic. How should her case be managed?
