1. Original article. Percentage hypochromic red cells and the response to intravenous iron therapy in anaemic haemodialysis.

Author

Jones, CH, Richardson, D, Ayers, S, Newstead, CG, Will, EJ, and Davison, AM

Abstract

Introduction: Iron deficiency is commonly encountered in haemodialysis (HD) patients and may be overcome by i.v. therapy. We have examined the percentage hypochromic red cells (%HRC) for predicting response to i.v. iron in subjects with a low serum ferritin. [ABSTRACT FROM PUBLISHER]

2. Extracellular fluid volume determined by bioelectric impedance and serum albumin in CAPD patients.

Author

Abstract

Aim.To investigate the relationship between serum albumin and extracellular fluid volume, as measured by multifrequency bioelectrical impedance, in stable patients treated by CAPD.Method.Fifty-nine stable CAPD patients were assessed. Serum albumin (bromocresol green) and CRP, age, dialysate to plasma (D/P) creatinine ratio, normalized protein catabolic rate (nPCR), daily urine and peritoneal protein losses, and extracellular fluid volume (Vecf) were measured in each patient. Vecf was calculated as a percentage of actual body weight (Vecf% ABW), of lean body mass derived from anthropometry (Vecf% LBM) and of total body water (Vecf% Vtbw). Comparisons between those with a normal serum albumin (37 g/l) and those with a low serum albumin (<37 g/l) were made by Mann-Whitney U test. Correlations with serum albumin were sought by Pearson's test. [ABSTRACT FROM PUBLISHER]

Abstract

In four normal subjects a 50-cm segment of the jejunum was perfused through a multilumen tube with either hypertonic (1300 mOsm/kg) or isotonic mixtures of mannitol and water at rates between 18 and 70 ml/min. There was no difference in the solute clearances produced by the two solutions. Mean clearances (ml/min) were urea 23, creatinine 8, urate 4. Ninety-five mmol of sodium and 3.8 mmol of potassium were removed during a 1-h perfusion period. Clearances of glucose, calcium, phosphate and protein were negligible. Mean free water clearance was 0.5 ml/min during isotonic perfusion and 22.4 ml/min during hypertonic perfusion. These clearances of urea and creatinine are similar to those previously reported during perfusion of the whole bowel in uraemic patients with isotonic mannitol and during segmental jejunal perfusion with glucose/sodium mixtures. Over the range of flow rates studied there was a positive linear relationship between perfusate flow rates might achieve clinically useful solute clearance. However, the efficacy of the method in prolonged perfusion of uraemic patients may be different from that seen in normal subjects.
