The Mean

Background Potential risk factors for 1-year mortality, including the peritoneal component of dialysis dose, residual renal function, demographic data, hematocrit, serum albumin, dialysate-to-plasma creatinine ratio, and blood pressure, were examined in a national cohort of peritoneal dialysis patients randomly selected for the Centers for Medicare and Medicaid Services End-Stage Renal Disease (ESRD) Core Indicators Project. Methods The study involved retrospective analysis of a cohort of 1219 patients receiving chronic peritoneal dialysis who were alive on December 31, 1996. Results During the 1-year follow-up period, 275 patients were censored and 200 non censored patients died. Among the 763 patients who had at least one calculable adequacy measure, the mean [± standard deviation (SD)] weekly Kt/V urea was 2.16 ± 0.61 and the mean weekly creatinine clearance was 66.1 ± 24.4 L/1.73 m2. Excluding the 365 patients who were anuric, the mean (±SD) urinary weekly Kt/V urea was 0.64 ± 0.52 (median: 0.51) and the mean (±SD) urinary weekly creatinine clearance was 31.0 ± 23.3 L/1.73 m2 (median: 26.3 L/1.73 m2). By Cox proportional hazard modeling, lower quartiles of renal Kt/V urea were predictive of 1-year mortality; lower quartiles of renal creatinine clearance were of borderline significance for predicting 1-year mortality. The dialysate component of neither the weekly creatinine clearance nor the weekly Kt/V urea were predictive of 1-year mortality. Other predictors of 1-year mortality ( p < 0.01) included lower serum albumin level, older age, and the presence of diabetes mellitus as the cause of ESRD, and, for the creatinine clearance model only, lower diastolic blood pressure. Conclusion Residual renal function is an important predictor of 1-year mortality in chronic peritoneal dialysis patients.

Peritoneal Solute Transport Rate

Background Fluid and sodium removal is often inadequate in peritoneal dialysis patients with high peritoneal solute transport rate, especially when residual renal function is declining. Method We studied the effects of using simultaneous crystalloid (glucose) and colloid (icodextrin) osmotic agents on the peritoneal transport of fluid, sodium, and other solutes during 15-hour single-dwell exchanges using 3.86% glucose, 7.5% icodextrin, and a combination fluid with 2.61% glucose and 6.8% icodextrin in 7 prevalent peritoneal dialysis patients with fast peritoneal solute transport rate. Results The combination fluid enhanced net ultrafiltration (mean 990 mL) and sodium removal (mean 158 mmol) compared with 7.5% icodextrin (mean net ultrafiltration 462 mL, mean net sodium removal 49 mmol). In contrast, the 3.86% glucose-based solution yielded negligible ultra-filtration (mean -85 mL) and sodium removal (mean 16 mmol). The combination solution resulted in significantly improved urea (+41%) and creatinine (+26%) clearances compared with 7.5% icodextrin. Conclusion A solution containing both crystalloid (glucose 2.61%) and colloid (icodextrin 6.8%) osmotic agents enhanced fluid removal by twofold and sodium removal by threefold compared with 7.5% icodextrin solution during a dwell of 15 hours, indicating that such a combination solution could represent a new treatment option for anuric peritoneal dialysis patients with high peritoneal solute transport rate.

Background: Peritoneal dialysis is used regularlly in treatment of ESRDs. Residual renal function (RRF) in these patients helps the adequacy of PD therapy very much. Objectives: 1. Study RRF of PD patients at Department of Nephro – Rheumatology, Hue Central Hospital. 2. Search the correlation between RRF and Kt/V. Patients and methods: 35 PD patients at Department of Nephro – Rheumatology, Hue Central Hospital. Measure RRF and Kt/V by formulars that depend on blood, urine and PD fluid samples. Results: Mean RRF of PD patients is 4.36 ± 13.8 ml/minute. There is a close correlation between RRF and Kt/V (r=0.79, p<0.01). Conclusion: RRF in PD patients correlates with Kt/V.

♦ Objective Helicobacter pylori (HP) infection has frequently been found in dialysis patients. Chronic infections induce overproduction of pro-inflammatory substances. Inflammation has been associated with cachexia and anorexia. We explored the relationship between HP infection, anorexia, and malnutrition in peritoneal dialysis (PD) patients. ♦ Patients and Methods The study included 48 clinically stable PD patients divided into four groups: HP+ with anorexia (group I, n = 12); HP+ without anorexia (group II, n = 4); HP- with anorexia (group III, n = 5); and HP- without anorexia (group IV, n = 27). Infection with HP was diagnosed by breath test. Anorexia was evaluated using a personal interview and an eating motivation scale (VAS). The VAS included five questions that are answered before and after eating. The questions concern desire to eat, hunger, feeling of fullness, prospective consumption, and palatability. Biochemical markers of nutrition and inflammation were also determined. ♦ Results At baseline, group I showed lower scores for desire to eat, hunger sensation, prospective consumption, and palatability. They also showed lower lymphocyte counts, prealbumin, transferrin, serum albumin, normalized equivalent of protein–nitrogen appearance (nPNA), and residual renal function (RRF). In addition, the same group showed higher levels of C-reactive protein (CRP) and more sensation of fullness than the remaining groups. In the entire series, we found significant linear correlations between the following markers of nutrition and certain questions on the VAS: albumin with before-lunch desire to eat ( r = 0.38, p < 0.05), and prealbumin with before-lunch hunger ( r = 0.41, p < 0.05) and after-lunch hunger ( r = -0.35, p < 0.05). Negative linear correlations were found between albumin and fullness before lunch ( r = -0.45, p < 0.01), and between prealbumin and before-lunch desire to eat ( r = -0.39, p < 0.05). Negative linear correlations were also seen between CRP and albumin ( r = -0.35, p < 0.05) and between CRP and prealbumin ( r = -0.36, p < 0.05). Similarly, CRP showed a negative correlation with before-lunch desire to eat ( r = -0.38, p < 0.05) and after-lunch desire to eat ( r = -0.45, p < 0.01). After HP eradication, group I showed a significant increase in markers of nutrition and in VAS scores for almost all questions. Simultaneously, they showed a decrease in CRP level. Significant differences were also found in lymphocyte count (1105 ± 259.4 cells/mm3 vs 1330.8 ± 316 cells/mm3, p < 0.05), nPNA (0.9 ± 0.16 g/kg/day vs 1.07 ± 0.3 g/kg/day, p < 0.05), prealbumin (26.7 ± 6.5 mg/dL vs 33.9 ± 56.6 mg/dL, p < 0.01), albumin (3.48 ± 0.3 g/dL vs 3.67 ± 0.35 g/dL, p < 0.05), CRP (1.16 ± 1.14 mg/dL vs 0.88 ± 1.2 mg/dL, p < 0.054), before-lunch desire to eat (56.6 ± 6.8 vs 72.2 ± 4, p < 0.001), after-lunch desire to eat (5.4 ± 2.6 vs 12.3 ± 2, p < 0.01), hunger before lunch (55.4 ± 5.4 vs 73.1 ± 4.6, p < 0.001), hunger after lunch (5.8 ± 2.9 vs 11 ± 4, p < 0.01), fullness before lunch (36.6 ± 10.3 vs 18.7 ± 8.8, p < 0.001), consumption after lunch (5 ± 4.7 vs 17.5 ± 18, p < 0.05), and palatability (61 ± 5.3 vs 74.1 ± 4.1, p < 0.001). ♦ Conclusion Infection with HP is associated with anorexia, inflammation, and malnutrition in PD patients. Eradication of HP significantly improves this syndrome. Residual renal function seem to have a protective effect on appetite preservation. The present study supports the hypothesis of the involvement of inflammation in the pathogenesis of malnutrition in PD patients.

Membrane Function

It is increasingly clear that peritoneal membrane transport status has clinical implications. The role of the peritoneum in dialysis delivery becomes para mount once residual renal function is lost, particularly as the membrane characteristics may change for the worse with time on treatment. These findings have several important implications: Clinicians need to take solute transport character istics into account as they assess their patients. Adverse effects of high solute transport include reduced ultrafiltration, solute removal (in particular, sodium), and increased peritoneal protein losses. A need exists to replace lost residual renal function, not just with enhanced solute removal, but also with adequate salt and water removal. The interpretation of urea and creatinine clear ances in anuric PD patients needs further consideration and validation. Hypoalbuminemia in PD patients will result from the combined effects of high protein losses, over hydration, comorbidity, and malnutrition.
