title: Nutritional intake during continuous ambulatory peritoneal dialysis.
abstract: The purpose of our study was to evaluate the adequacy of nutrition intake in continuous ambulatory peritoneal dialysis (CAPD) patients. In 34 patients, diet histories were taken every 1-3 months simultaneously with adequacy parameter estimations and total nitrogen measurements in dialysate and urine. The results were normalized to 1 kg of ideal (IBM) or lean (LBM) body mass. During the 2-year study period, there was a decrease in the intake (g/kg IBM/day) of carbohydrates (4.2 +/- 1.5 vs 3.4 +/- 1.2), fat (1.3 +/- 0.6 vs 0.8 +/- 0.2), and protein (1.18 +/- 0.43 vs 0.85 +/- 0.11); daily protein intake values were higher than those of protein catabolic rate (0.91 +/- 0.19 vs 0.77 +/- 0.17). Nitrogen balance was positive (6.6 +/- 2.1 vs 1.8 +/- 2.7 g/day). The daily energy intake (40 +/- 11 vs 32 +/- 13 kcal/kg IBM/day) did not show any tendency of increasing or decreasing, stable or otherwise. The mean intake of vitamins and minerals (except Na, K, P) was less than in healthy persons; moreover, in most cases vitamin intake did not reach values recommended for CAPD patients. Protein, mineral, and vitamin intake is usually unsatisfactory in CAPD patients. However, a positive nitrogen balance can be obtained when the energy intake is close to the optimal value of 35 kcal/kg/day.
