Staphylococcal infections are a major cause of catheter infections and peritonitis in peritoneal dialysis patients. Since catheter-related infections are associated with nasal carriage of Staphylococcus aureus in this population, we studied the effect of intermittent rifampin, an antibiotic known to decrease S aureus nasal carriage, on catheter-related(More)
Eighteen hemodialysis, 12 chronic ambulatory peritoneal dialysis (CAPD), and 20 renal transplant patients performed maximal treadmill exercise tests. Heart rates and blood pressures were determined every minute and maximal oxygen consumption was measured directly. Exercise capacity as measured by VO2 max is low in dialysis patients and similar to sedentary(More)
Glomerulonephritis following pneumococcal infection has been observed, but possible immunopathologic mechanisms have not been adequately explored. Multiple serologic studies as well as light, immunofluorescence and electron microscopic evaluation of kidney biopsy tissue from a 4 year old girl with pneumococcal glomerulonephritis were performed. Clinical(More)
A prospective trial of warfarin and dipyridamole was performed in patients with membranoproliferative glomerulonephritis. Eighteen completed either a control or treatment year, and 13 completed both a control and treatment year. To obviate the bias of excluding control patients who had renal failure after one year, both an unpaired and a paired analysis(More)
Proteinuria and nephrotic syndrome due to recurrent disease may develop after renal transplant in patients with focal glomerular sclerosis (FGS). The rapid onset of proteinuria in many of these patients suggests a possible humoral mediator. We studied serum from a patient who has had recurrence of nephrotic syndrome and FGS after two cadaveric renal(More)
Recent evidence suggested that noncompliance (NC) with continuous ambulatory peritoneal dialysis (CAPD) exchanges may be more common in US than in Canadian dialysis centers. This issue was investigated using a questionnaire-based method in 656 CAPD patients at 14 centers in the United States and Canada. NC was defined as missing more than one exchange per(More)
Of 475 renal biopsles examined by immunofluorescence, IgA was seen located selectively in the glomerular mesangium of 18 patients. These patients were generally young men and had hematuria, only minimal proteinuria, and normal renal function. Glomerular lesions consisted of focal segmental capillary hypercellularity or sclerosis and mesangial thickening due(More)
63 adult patients with advanced renal failure were interviewed to evaluate their exposure to chronically contacted or inhaled toxic substances. Grading of exposure revealed that patients with biopsy-proven primary proliferative glomerulonephritis and patients with a clinical presentation consistent with glomerulonephritis had significantly greater exposure(More)
The case of a patient with diabetes mellitus and renal failure is presented and discussed. This case represents the very successful course of a diabetic patient who received peritoneal dialysis for 14 years. Not all patients with end-stage renal disease (ESRD) from diabetic nephropathy are this fortunate. The success and complications of dialytic modalities(More)
