  Diuretic-resistant congestive heart failure in the form of type 2 cardiorenal syndrome is a problem of growing significance in everyday clinical practice because of high morbidity and mortality.Diuretic-resistant congestive heart failure in the form of type 2 cardiorenal syndrome is a problem of growing significance in everyday clinical practice because of high morbidity and mortality. There has been scant progress in the treatment of overhydration, the main cause of symptoms in this group of patients. The aim of our review is to present recent advances in the ultrafiltration therapy of congestive heart failure, with special attention to the new dedicated device for extracorporeal isolated ultrafiltration, as well as modifications of peritoneal dialysis in the form of peritoneal ultrafiltration with icodextrin solution and incremental peritoneal dialysis. Technical and clinical features, costs and potential risks of available devices for isolated ultrafiltration are presented. This method should be reserved for patients with true diuretic resistance as part of a more complex strategy aiming at the adequate control of fluid retention. Peritoneal ultrafiltration is presented as a viable alternative to extracorporeal ultrafiltration because of medical and psychosocial benefits of home-based therapy, lower costs and more effective daily ultrafiltration. In conclusion, large, properly randomized and controlled clinical trials with long-term follow-up will be essential in assessing the logistics and cost-effectiveness of both methods. Most importantly, however, they should be able to evaluate the impact of both methods on preservation of renal function and delaying the progression of heart failure by interrupting the vicious circle of cardiorenal syndrome. Our review is supplemented with the case report of the use of peritoneal ultrafiltration with a single 12-hour nighttime icodextrin exchange as a life-saving procedure in a patient with congestive heart failure resistant to pharmacological treatment.

  This report describes the use of continuous peritoneal dialysis (PD) as an alternative to hemodialysis (HD) in a patient with type 2 cardiorenal syndrome in the course of congestive heart failureThis report describes the use of continuous peritoneal dialysis (PD) as an alternative to hemodialysis (HD) in a patient with type 2 cardiorenal syndrome in the course of congestive heart failure resistant to standard pharmacological treatment. A 39-year-old man presented with a 24-year history of progressive heart failure. Ineligibility for heart transplant and previous inefficient treatment with different modifications of HD reduced his treatment options to PD. After 7 months of continuous PD (1 overnight exchange with icodextrin and 2 daily standard continuous ambulatory PD exchanges) his overall condition significantly improved compared with his status while on HD. An increase from NYHA class IV to class II, increase in left ventricular ejection fraction from 50% to 55%, decrease in right ventricular systolic pressure from 73 to 53 mmHg, and improvement in the quality of life enabled him to resume his daily activities.

  INTRODUCTION: Dialysis fluid containing icodextrin is used in patients on peritoneal dialysis (PD) because of its significant ultrafiltration properties. The use of the fluid in treating patientsINTRODUCTION: Dialysis fluid containing icodextrin is used in patients on peritoneal dialysis (PD) because of its significant ultrafiltration properties. The use of the fluid in treating patients with congestive heart failure resistant to diuretics has also been reported. OBJECTIVES: The aim of the study was to evaluate water peritoneal transport during a 16-hour dialysis exchange performed using icodextrin-containing dialysis fluid. PATIENTS AND METHODS: Eleven clinically stable patients were enrolled in the study (5 women and 6 men; mean age, 50.4 +/- 18.3 years), treated with PD for 26.9 +/- 22.4 months. Water transperitoneal transport was evaluated using a modified version of Babb-Randerson-Farrell thermodynamic model of membrane transport with human albumin marked with iodine as the marker of intraperitoneal volume. Based on blood and dialysate samples collected during the 16-hour dialysis exchange, the intraperitoneal volume of dialysate and dialysate reverse absorption were calculated. RESULTS: There were no clinical complications associated with the use of icodextrin fluid during the study. A significant increase in intraperitoneal volume of dialysate (950 ml on average) compared to the initial value was observed in the whole group at the 16th hour of the exchange. CONCLUSIONS: The study demonstrated that dialysis fluid with icodextrin ensured effective ultrafiltration during a 16-hour dialysis exchange. This indicates its potential usefulness in the treatment of patients with severe congestive heart failure with or without coexisting end-stage renal disease.

  The aim of the study was the comparison of peritoneal transport of solutes and water during dialysis with presently used 1.1% amino acid solution in relation to 1.36% glucose solution. 20 clinicallyThe aim of the study was the comparison of peritoneal transport of solutes and water during dialysis with presently used 1.1% amino acid solution in relation to 1.36% glucose solution. 20 clinically stable patients on CAPD for 50.0 +/- 27.6 months were enrolled into the study. On the basis of blood and dialysate samples taken during 4-hour CAPD, intraperitoneal dialysate volume and diffusive mass transport coefficients (KBD) for: glucose, creatinine, urea, sodium, potassium and total protein were calculated. Intraperitoneal dialysate volume was higher in the case of amino acid solution in comparison to glucose solution. The KBD values for the investigated solutes were higher when amino acid solution was used, but for glucose and sodium the KBD values were statistically significantly higher. In conclusion, the differences in transperitoneal transport of solutes and water between both solutions found in our study suggest better clinical usefulness of amino acid solution than standard glucose solution for achieving adequate ultrafiltration.

The illustration of this problem is the case of 70-year-old patient treated with automated PD, in whom recurrent episodes of peritonitis (Escherichia coli) were typical of "abdominal catastrophe" and were probably caused by microperforations of the colon in the course of diverticulosis.

In all groups adequacy of haemodialysis (HD) measured by Kt/V was similar. Every month the following data were determined: Ca, P, CaxP product, HCT, HGB, Fe, transferrin saturation (TSAT) and weekly dose of rHuEPO. Patients with chronic infections, neoplastic diseases or those after blood transfusions were excluded from the study. Significantly higher weekly dose of rHuEPO was needed in patients with iPTH > 300 pg/ml to obtain similar correction of renal anaemia in comparison with patients with iPTH from 100 to 300 pg/ml. There were no statistically significant differences between the groups with respect to other data except significantly higher values of Cas in the group with iPTH > 300 pg/ml. CONCLUSION: Higher doses of rHuEPO to obtain the same correction of renal anaemia are necessary only in patients with iPTH > 300 pg/ml.

  OBJECTIVE: To evaluate peritoneal transport of fluid and solutes in continuous ambulatory peritoneal dialysis (CAPD) patients using amino acid (AA)-based versus glucose-based dialysis solutions.OBJECTIVE: To evaluate peritoneal transport of fluid and solutes in continuous ambulatory peritoneal dialysis (CAPD) patients using amino acid (AA)-based versus glucose-based dialysis solutions. METHODS: Using iodine-labeled human serum albumin ((125)I-HSA) as intraperitoneal volume marker, peritoneal transport was investigated in a group of 20 clinically stable patients (11 females and 9 men, age 53 +/- 15 years) on CAPD for 15 - 101 months. Two paired 4-hour dwells, one with 1.36% glucose and one with 1.1% AA dialysis solution, were performed in each patient. Intraperitoneal dialysate volume, fluid absorption rate, and diffusive mass transport coefficients (K(BD)) and sieving coefficients (S) for glucose, creatinine, urea, potassium, and total protein were estimated for each dwell study. Dwell studies with AA solution were used to estimate K(BD) values for individual AAs. RESULTS: Intraperitoneal dialysate volume was higher for AA solution in comparison with glucose solution due to the higher osmolality of the AA solution. No statistically significant difference was found for K(BD) or S for creatinine, urea, potassium, or total protein in the dwell studies with either solution, whereas K(BD) for glucose was higher with AA than with glucose solution. Mean values of K(BD) of AA were similar but with high standard deviation, reflecting inter-individual variations in peritoneal transport rate. CONCLUSION: Our results indicate that the AA peritoneal transport rate is strongly dependent on transport characteristics of the individual peritoneal membrane.
