The contribution of peritoneal cavity lymphatic absorption to ultrafiltration kinetics and solute clearances in continuous ambulatory peritoneal dialysis was evaluated in patients with normal (group 1) and high (group 2) peritoneal permeability X area during 4-h exchanges using 2 liters 2.5% dextrose dialysis solution with 30 g added albumin. Cumulative lymphatic drainage in all continuous ambu...

BACKGROUND AND METHODS Icodextrin 7.5% is an iso-osmolar, glucose polymer-containing peritoneal dialysis solution with an ultrafiltration potential similar to glucose 3.86%. We compared in an open, randomized, prospective study the ultrafiltration potential of icodextrin with that of glucose during the daytime dwell of 23 patients treated with automated peritoneal dialysis (CCPD). RESULTS Day...

Ultrafiltration was performed in nine patients with congestive cardiac failure that was refractory to conventional medical treatment. A mean of 12 X 7 litres of fluid was removed, and there was a sustained symptomatic improvement in all patients. Weight loss continued after ultrafiltration and a sustained increase in serum sodium concentration was also noted. A transient fall in right atrial pr...

Detection of Legionella pneumophila antigen in urine by enzyme immunoassay (EIA) or by immunochromatographic testing (ICT) has proven rapid, sensitive, and specific for diagnosing legionellosis (2, 3, 5, 6). Although it requires added processing time, the use of concentrated urine (CU) obtained by selective ultrafiltration significantly improves the sensitivity (1) of antigen detection. We asse...

The EPA method 1623 is designed specifically for the detection of Cryptosporidium and Giardia, but the method has some issues with low and variable recoveries. Ultrafiltration has been used effectively for microorganism recovery from water samples but is not approved by the EPA. To determine the efficacy of using ultrafiltration, 10-L tap water and surface water samples were seeded with Cryptos...

Patients with histoplasmosis may test falsely negative for Histoplasma capsulatum antigenuria. In some cases antigen is present at levels below the assay's detection limit, and ultrafiltration could improve sensitivity. Antigen was detected following ultrafiltration in 73.8% of falsely negative specimens versus 2% of controls. Ultrafiltration improved sensitivity with a small reduction in speci...

in the present study, micellar-enhanced ultrafiltration (meuf) was used to remove manganese (mn) (ii) from synthetic wastewater. the effects of different operational conditions on the filtration performance of meuf or the membrane were studied. it was found that the transmembrane pressure has a major influence on the permeate flux and an insignificant effect on the rejection coefficient. the pe...

OBJECTIVES We sought to determine if ultrafiltration before intravenous (IV) diuretics in patients with decompensated heart failure and diuretic resistance results in euvolemia and early discharge without hypotension or worsening renal function. BACKGROUND Heart failure patients with renal insufficiency and diuretic resistance have increased hospital mortality and length of stay. Peripheral v...

BACKGROUND Ultrafiltration failure is a significant cause of technique failure for peritoneal dialysis and subsequent transfer to hemodialysis. SUMMARY Ultrafiltration failure is defined as failure to achieve at least 400 ml of net ultrafiltration during a 4 h dwell using 4.25% dextrose. Four major causes of ultrafiltration failure have been described. A highly effective peritoneal surface ar...
