Care of the diabetic patient with end-stage renal disease.
Diabetic nephropathy is now the leading cause of renal failure in patients referred for uremia therapy. The diabetic patient is a complicated treatment problem from the first detection of microalbuminmuria, at which time decisions regarding choice of antihypertensive and strictness of metabolic control assume increasing importance. At present, our policy is to advocate strict control of blood pressure, aiming for a systolic blood pressure of less than 140 mm Hg and a diastolic blood pressure of less than 80 mm Hg. We attempt to maintain hemoglobin Alc levels at less than 8%, if the patient does not develop frequent episodes of hypoglycemia. We extend these recommendations to the patient with frank proteinuria, nephrotic syndrome and early uremia, understanding that strict metabolic control may be impossible as patients lose GFR. In addition, we recommend avoidance of a high protein diet in the early nephropathic diabetic, with diet of approximately 1 gm/kg/d. As renal failure progresses, we embark on an analysis of the patient's abilities, lifestyle, and social support. At a GFR of approximately 10 mL/min, we initiate preparations for uremia therapy. If a willing and appropriate living related kidney donor is available, the patient is referred for cardiovascular evaluation and kidney transplantation performed subsequently. If no donor is immediately available, we refer the patient for vascular access placement and/or insertion of a Tenckhoff peritoneal catheter, if preferred. Most of these predialysis patients also undergo screening for placement on the cadaveric kidney transplant list, including cardiac work-up as is done for the patients who receive living-related renal transplants. Because of the long waiting list in Brooklyn, and the universal shortage of organ donors, many of these patients eventually end up on dialysis for some period of time. Other extrarenal problems (urologic, ophthalmologic) are addressed at initial referral and followed up, in hopes of maintaining the patient in optimal physical shape as uremia progresses. The care of the diabetic patient with ESRD ideally involves a consortium of caregivers. We include a nurse-educator familiar with options for uremia therapy, a podiatrist, a cardiologist, and often a urologist, an endocrinologist, and a gastroenterologist. In addition, a social worker is helpful to assess psychologic difficulties in adjustment to uremia, socioeconomic considerations, and rehabilitation status. Finally, the nephrologist, as coordinator of this team works with the vascular or transplant surgeon, to facilitate the transition to ESRD and its therapy.
