Plasma Oxalate in Chronic Renal Failure and Normal Subjects: Methodological Problems

Plasma level and renal clearance of oxalate in normal subjects and in patients with primary hyperoxaluria or chronic renal failure or both.

1. Plasma oxalate has been measured by a radioisotopic method applicable to all concentrations of plasma oxalate and renal function, and also by an enzymatic method which was only applicable to raised concentrations of plasma oxalate. 2. Where the two methods could be applied simultaneously, the agreement between them was good. 3. Plasma oxalate was 86% ultrafiltrable at concentrations of up to...

Plasma oxalate concentration and secondary oxalosis in patients with chronic renal failure.

To examine the association between hyperoxalaemia and secondary oxalosis, measurement of plasma oxalate concentration was combined with a search for tissue deposition of calcium oxalate crystals in patients with chronic renal disease. Two groups of patients were studied. In the first, samples of the inferior epigastric artery were taken from 35 patients at the time of renal transplantation. In ...

Association of hemodialysis and pruritus in chronic renal failure

Background and aim: Pruritus is a common disabling problem in patients with end stage renal disease. Several studies has recorded the relation between pruritus with hemodialysis in chronic renal failure (CRF) patients. This study was designed to evaluate the effect of hemodialysis on pruritus of patients with CRF.Materials and Methods: After recording the demographic data and the diagnosis of d...

Etiology of Chronic Renal Failure in Children and Lnfants

Chronic renal failure is an uncommon disease in children with some difference in the etiology in different countries. In this study on 180 children (From 1987 to 1997 in Shiraz) with age range of 3 months to 15 years (mean 8.6±4.2 years). The male to female ratio was 1. 57: 1. The etiology of chronic renal failure in decreasing order of frequency were: reflux nephropathy (25 % ) , glbmerular di...
