Objective To evaluate the influence of 1.1% amino acid dialysis solution (AADS) on parameters of nutrition in continuous ambulatory peritoneal dialysis (CAPD) patients. Study Design Studies were performed in 8 men, using AADS for the overnight exchange. Before starting AADS, food intake, nutritional status, and laboratory indices were evaluated and compared to the respective parameters obtained after 3 and 6 months of treatment with AADS, as well as after 3 months of AADS withdrawal. With the start of AADS, doses of antacids were increased and modified during AADS administration; the modified doses were continued through 3 months after cessation of AADS. Another group of CAPD patients using standard dialysis solutions served as controls. In these patients the same parameters were evaluated four times at 3-month intervals. Results Administration of AADS resulted in: (1) 91% absorption of amino acids and improvement of serum amino acid pattern; (2) no change in nutritional intake during the treatment, but after the 3 months of AADS therapy, levels of nutrient intake were lower than those 3 months after withdrawal of AADS with correction of metabolic acidosis; (3) no change in indices of nutritional status, but 3 months after AADS discontinuation, total body weight, lean body mass, and body mass index were significantly higher than those shown after 3 months of treatment; (4) an increase in hemoglobin concentration, hematocrit, BUN, and blood H+. The examined parameters were not significantly changed in patients treated for 9 months with standard dialysis solutions exclusively. The values of nitrogen balance obtained during AADS administration and after 3 months of AADS withdrawal were significantly higher than those obtained in the respective periods in the control group. The blood pH, pCO2, and HCO3– in the last period of the study were higher in the AADS group than in the control group. Conclusion In relatively well-nourished CAPD patients, overnight AADS administration results in increased serum concentration of amino acids without changes in other nutritional parameters. The use of AADS should be associated with increased doses of antacid medication, which abolishes the metabolic effects of acidosis that develop during AADS administration and facilitates positive nitrogen balance.

Reports in the literature have linked a low phosphatidylcholine content in continuous ambulatory peritoneal dialysis {CAPD) effluent to ultrafiltration loss. Clinical evidence suggests that adding phosphatidylcholine to the dialysis solution enhances ultrafiltration. A clinical study has been designed to clarify the effect of phosphatidylcholine on ultrafiltration in CAPD patients with normal ultrafiltration. A weekly measurement of the peritoneal equilibration test was conducted per patient in the hospital. A comparison between the control dialysis solution {three-week period) and the phosphatidylcholine premixed solution {three-week period) was performed on a total of 12 patients. This study shows that a phosphatidylcholine premixed dialysis solution significantly enhances ultrafiltration. Since ultrafiltration per osmotic driving force (mUg glucose) is enhanced, the patient's glucose load per day is reduced to achieve equal ultrafiltration. In the presence of phosphatidylcholine, peritoneal permeability remained unchanged, as indicated by membrane transport characteristics. No side effects were observed.

Background Results of peritoneal equilibration test (PET) suggest prolonged effect of polyglucose dialysis solution (PG-DS) on peritoneal permeability. Objectives An evaluation of dialysate-to-plasma ratio (D/P) of urea, D/P creatinine, and D/D0 glucose (ratio of dialysate glucose at designated dwell time to dialysate glucose at 0 dwell time), and mass transfer area coefficients (KBD) of these solutes in PET before introduction, during administration, and after discontinuation of PG-DS in patients treated with continuous ambulatory peritoneal dialysis (CAPD). Design Single-center prospective study with PG-DS; retrospective selection of the control group. Setting Peritoneal dialysis unit in a university hospital. Patients Fourteen patients (11 males; age 45.1 ± 8.5 years) treated with CAPD for 17.5 ± 9.9 months. 7.5% PG-DS was used for the overnight exchange. After discontinuation of the PG-DS, standard dialysis solutions, as previously used, were reintroduced. The control group was selected to match both CAPD duration and peritoneal permeability of the patients in the PG-DS group at the start of the study. Methods Standard PET was carried out at 1.6 ± 0.8 months before the introduction of PG-DS (study period I, n = 14), after 1.2 ± 0.6 months’ use of PG-DS (study period II, n = 14), after 4.4 ± 0.8 months’ use of PG-DS (study period III, n = 11), after 8.8 ± 2.2 months’ use of PG-DS (study period IV, n = 9), and at 2.0 ± 0.6 months after PG-DS discontinuation (study period V, n = 11). Patients in the control group underwent PET at similar time intervals (control periods I – V). Results In the PG-DS group, a tendency toward increased peritoneal permeability for urea and creatinine was shown during the consecutive study periods. D/D0 glucose was significantly higher only in the PET performed during use of PG-DS (periods II – IV) compared to results obtained in period I. In the control group, both D/P and KBD of both urea and creatinine remained unchanged, but KBD glucose was higher in the first 2 hours of the PET in control period V compared to respective values in control period III. Conclusion Changes in peritoneal permeability are observed in CAPD patients treated with PG-DS. These changes may be at least partially related to the administration of polyglucose.

In order to evaluate peritoneal membrane function and responsiveness of peritoneal microcirculation to vasoactive agents in long-term continuous ambulatory peritoneal dialysis (CAPD) patients, we studied peritoneal clearances of urea (Curea) and creatinine (Ccr), protein concentrations in drained dialysate (D PC), peritoneal glucose absorption (% GA), and drained dialysate volume ( VD) before and after nitroprusside (NP) addition to dialysis solution in 17 long-term CAPD patients (mean duration of CAPD: 52 months) and the results were compared to those of 18 patients who were just trained for CAPD (mean duration: 0.6 month). There were no differences in the control (without NP) Curea, Ccr, D PC, %GA, and VD between the new and long-term CAPD patients. Curea, Ccr, and D PC increased significantly with NP in both new and long-term patients. Curea and Ccr with NP were not different between the new and long-term patients but D PC with NP was significantly lower in the long-term CAPD patients. The results of this study suggest that peritoneal solute clearances and the responsiveness of peritoneal microcirculation to NP remain unchanged after four years of CAPD, despite recurrent episodes of peritonitis.

The changes in plasma and dialysate amino acids (AA) in 7 continuous ambulatory peritoneal dialysis (CAPD) children after dialysis with a 1% AA solution were compared with a glucose-containing solution. During the AA exchange, the plasma levels of individual AA reached their peaks after 1 h, with their percentage increments significantly correlated (p < 0.001) with the ratio of the amount of AA in the bag to the basal plasma concentration. The plasma concentration of methionine, valine, phenylalanine, and isoleucine remained higher than the basal value at 4 h. The amount of AA absorbed was 66% after 1 h, and 86% after 4 h and 6 h, corresponding to 2574 ± 253 μmollkg body wt. During glucose-dialysis (1.36%), levels of histidine, methionine, valine, phenilal-anine, and isoleucine were significantly decreased in plasma after 1 h, and stayed low throughout the dialysis period. The loss of AA with the peritoneal effluent was 116 ± 69 μmol/kg/body wt. From this study, it seems that using an AA dialysis solution, with 1 exchange per day, might limit the daily glucose load and compensate for AA losses by supplying an extra amount of AA and by reducing the loss of other AA not contained in dialysis solutions. The AA pattern in plasma following AA-dialysis resembles that observed after a protein meal, with no signs of persistently high, nonphysiological levels.
