1% amino acid peritoneal dialysate: single-cycle study in diabetic patients with end-stage renal disease.

Uremia is associated with multiple abnormalities of carbohydrate and protein metabolism, which are partially corrected by continuous ambulatory peritoneal dialysis with dextrose-based solutions. The hormonal and metabolic effects of amino acid (AA)-based peritoneal dialysis have been studied in nondiabetic uremic patients. Such solutions may be particularly suitable for diabetic patients with end-stage renal disease provided the safety and efficacy of such solutions can be established. We have studied and compared the metabolic and hormonal responses to a single-cycle exchange of dextrose versus a 1% AA-based continuous ambulatory peritoneal dialysis solution in six diabetic patients with end-stage renal disease. In the fasting state and under similar free insulin concentrations, use of the AA solution led to a higher mean glucose concentration (109 +/- 16 mg/dL with dextrose solution v 128 +/- 25 mg/dL with AA solution, P < 0.05). Levels of alanine, lactate, pyruvate, glycerol, non-esterified fatty acids, and triglycerides were similar with the use of either solution. Use of the AA-based solution led to increases in the mean values of the branched chain AAs for the period of the study (valine 131 +/- 10 mumol/L with dextrose solution v 331 +/- 40 mumol/L with AA solution, P < 0.01; leucine 72 +/- 7 mumol/L with dextrose solution v 129 +/- 11 mumol/L with AA solution, P < 0.01; isoleucine 48 +/- 5 mumol/L with dextrose solution v 103 +/- 11 mumol/L with AA solution, P < 0.01).(ABSTRACT TRUNCATED AT 250 WORDS)
