Taste perception of children with chronic renal failure.
Taste sensitivity and preference in the suprathreshold ranges were compared for 20 pediatric patients with renal disease and 15 children with normal renal function. Nine patients had chronic renal insufficiency, and 11 had endstage renal disease. Subjects were also evaluated for various dietary, anthropometric, and biochemical parameters. All subjects were asked to pull out a tape measure to rate the strength of five varying concentrations of aqueous solutions of sucrose, sodium chloride, and quinine sulfate. The subjects' abilities to judge increasing concentrations with greater perceived intensity were measured by calculating individual and group slopes. No significant differences in the values were found between the groups. Similarly, no significant differences in mean peak preference concentrations were found between the groups. The patients with renal disease were found to be considerably growth retarded (height and weight less than 5th percentile), with a mean caloric intake less than 65% of the RDA even after an adjustment had been made for height. Serum zinc levels were all normal.
