Case Study: Man With Type 2 Diabetes and Stage 1 Kidney Disease on Atkins-Like Diet
C.S. is a 45-year-old Hispanic man with a 10-year history of type 2 diabetes. He has a glycated hemoglobin of 7.0% and a blood pressure of 130/80 mmHg, treated with an angiotensin-converting enzyme inhibitor for the past 2 years. He has stable background retinopathy and is a nonsmoker. His BMI has been 30 (height 5'10'', weight 210 lb) for the past year. However, lately, he has put himself on the latest high-protein diet (i.e., the Atkins diet). His weight has dropped by 10 lb, his fasting serum triglyceride level has fallen from 185 to 130 mg/dl, and his blood pressure has decreased to 120/78 mmHg. His LDL cholesterol has remained stable at 102 mg/dl on a statin. His serum creatinine is 0.9 mg/dl, and his 24-hour urine shows a significant increase in microalbumuria from 100 mg/24 hours last year to the current 200 mg/24 hours. He has stage 1 chronic kidney disease indicating kidney damage, with a normal glomerular filtration rate (GFR) of 98 ml/min/1.73 m2.
It is likely that microalbuminuria is the start of a continuum progressing to macroalbuminuria and proteinuria. Microalbuminuria predicts renal disease in diabetes (both type 1 and type 2) and relates to premature mortality. Microalbuminuria is also a marker for pronounced diabetic vascular disease (endothelial dysfunction and chronic low-grade inflammation). Abnormal albuminuria is a major
