Impaired intestinal barrier function measured by differently sized polyethylene glycols in patients with chronic renal failure.
The intestinal mucosa plays a fundamental role as the site for absorption of nutrients, and as an important barrier from potentially harmful agents in the intestinal lumen. Little is known of the permeability properties of the intestinal mucosa in uraemic patients. The intestinal permeability to differently sized polyethylene glycols (PEGs; range 326-1254 daltons) was studied in nine patients w...
متن کاملImpaired muscle oxygen transfer in patients with chronic renal failure.
We hypothesized that impaired O2 transport plays a role in limiting exercise in patients with chronic renal failure (CRF). Six CRF patients (25 +/- 6 yr) and six controls (24 +/- 6 yr) were examined twice during incremental single-leg isolated quadriceps exercise. Leg O2 delivery (QO2(leg)) and leg O2 uptake (VO2(leg)) were obtained when subjects breathed gas of three inspired O2 fractions (FI(...
متن کاملDecreased number and impaired angiogenic function of endothelial progenitor cells in patients with chronic renal failure.
OBJECTIVE Increased risk of cardiovascular disease in patients with chronic renal failure (CRF) has been explained by accelerated atherosclerosis and impaired angiogenesis, in which endothelial progenitor cells (EPCs) may play key roles. We hypothesized that altered EPC biology may contribute to the pathophysiology of CRF. METHODS AND RESULTS EPCs were isolated from CRF patients on maintenanc...
متن کاملAltered intestinal function in patients with chronic heart failure.
OBJECTIVES We evaluated morphology and function of the gut in patients with chronic heart failure (CHF). BACKGROUND Intestinal translocation of bacterial endotoxin may contribute to the inflammatory state observed in patients with CHF. The morphology and function of the gut may be abnormal. METHODS We studied 22 patients with CHF (age 67 +/- 2 years, left ventricular ejection fraction [LVEF...
متن کاملSalivary function in patients with chronic renal failure undergoing hemodialysis.
PURPOSE The aim of this study was to evaluate the changes in salivary gland function in patients with chronic renal failure (CRF) undergoing hemodialysis. METHODS The group consisted of 23 patients with CRF (13 female, 10 male; mean age: 40 +/- 13 yr) and 14 healthy control subjects (mean age: 40 +/- 13 yr). All underwent dynamic salivary gland scintigraphy with gustatory stimulation. After i...
