Biochemical and neurophysiological parameters in hemodialyzed patients with chronic renal failure

Serum concentrations of accumulated solutes, standard clinical biochemistry, and parameters of clinical neuropathy, were determined in hemodialyzed patients with chronic renal failure. Analyses by high-performance liquid chromatography included creatinine, pseudouridine, urate, p-hydroxyhippuric acid, hippuric acid, indoxylsulfate, tryptophan, tyrosine, 3-indoleacetic acid, and a number of as-yet unidentified solutes. Standard biochemical parameters were measured; aluminium, parathyroid hormone, serum electrolytes and enzymes, hemoglobin, bilirubin, phosphate and urea. Measures of clinical neuropathy were: maximal motor nerve conduction velocities, and Hoffmann reflex latency. Several solutes had higher concentrations when nerve function was impaired. Serum total LDH, and total calcium levels correlated positively with values of the Hoffmann reflex, as did serum hippuric acid concentrations. Concentrations of p-hydroxyhippuric acid and two fluorescent compounds correlated negatively with motor nerve conduction velocities. In principal component analysis a number of ‘organic acid-like’ substances, like hippuric acid and p-hydroxyhippuric acid, were shown to associate multivariately with the neurophysiological variables while urea, creatinine, urate and phosphate were not

The effect of fish oil on lipid profile and viscosity of erythrocyte suspensions in CAPD patients

In this study we investigated the effects of a daily supplementation of 6 g Super-EPA containing 3 g of the marine fatty acids eicosapentaenoic acid (EPA, C 20:5 omega-3) and docosahexaenoic acid (DHA, C 22:6 omega-3) for a period of 8 weeks in nine patients on continuous ambulatory peritoneal dialysis. The concentrations of both HDL2 cholesterol and total HDL cholesterol increased (P<0.05) and there was a marked reduction in triglycerides (P<0.05). The viscosity of erythrocyte suspensions at a haematocrit of 0.80 decreased at most shear rates, suggesting an increased erythrocyte deformability. Mean corpuscular volume decreased (P<0.05) and total cholesterol and phospholipids in the erythrocyte membrane increased. We conclude that the daily use of 3 g of omega-3 polyunsaturated fatty acids by CAPD patients produces favourable effects on lipid profile and viscosity of erythrocyte suspensions, which may be of importance in protecting these patients against a further progression of atherosclerosis
