Abstract
In recent years studies on hemodialysis are being carried out extensively for facilitating rehabilitation of patients on maintenance hemodialysis. As to nutritional intake of minerals such as potassium, phosphate and magnesium by the patients with chronic renal failure, there are no recommended allowances and only insufficient information available although their importance is fully recognized. Many of the patients on maintenance hemodialysis are therefore undergoing perfunctory dietary therapy based on periodical biochemical test data alone. We therefore measured the mineral contents in the basal hemodialytic diets and the mineral concentration in serum of these patients in order to assess the correlation therebetween.
The results are summarized as follows:
1) Significant differences were found in the contents of K (p<0.05), P (p<0.05), Ca (p<0.05) and Na (p<0.01) in the diet between patients on maintenance hemodialysis and healthy control subjects. No significant difference was noted in Fe and Mg contents.
2) Correlation coefficients between the mineral intake in patients of maintenance hemodialysis and serum concentrations of these minerals prior to hemodialysis were as follows: r=0.39 for K, r=0.81 (p<0.01) for Ca, r=0.15 for P, r=0.82 (p<0.01) for Mg, r=0.92 (p<0.001) for Fe and r=0.84 (p<0.01) for Na.
