The importance of dietary protein in the zinc deficiency of uremia.

The pathogenesis of zinc deficiency and its relationship to hypogeusia were studied in three chronic dialysis units in Toronto. The difference between low plasma zinc levels at two of the hospitals compared to the normal levels in the third hospital was significantly related to levels of dietary zinc intake which in turn was due to the levels of dietary protein intake. Thus one cause of zinc deficiency in chronic uremia is dietary protein deprivation.

Dialysis hyperlipemia: response to dietary manipulations.

The effects of dietary manipulations on plasma lipid concentrations were studied over a 3 month period in 8 stable uremic patients on dialysis. Each of the 4 diets was of 3 weeks' duration, and consisted of the following periods: Control (regular diet), high carbohydrate (60% of total calories ingested), control, and a low carbohydrate diet (20% of total calories ingested). The patients' weight remained stable throughout the study.

Initial experiences with continuous ambulatory peritoneal dialysis.

Continuous ambulatory peritoneal dialysis (CAPD) has been initiated on 51 patients: 27 females (mean age -- 43.9 years) and 24 males (mean age -- 46.4 years).
