The results are described of a combined nutritional (supplemented diet) and dialytic (once a week hemodialysis) therapy, employed in 17 selected chronic uremics for a mean period of 18.2 months/patient. The clinical findings, blood chemical abnormalities and changes of renal function were examined and compared with those of patients on the standard thrice-a-week dialysis schedule and free diet. The clinical findings were not significantly different in the two groups. The residual renal function of patients on combined therapy declined faster than in patients on conservative treatment, but at a slower rate than in those on thrice-a-week dialysis. The time averages of serum urea, methylguanidine and phosphate concentrations and their postdialytic rebounds were lower in the patients on combined therapy than in those on thrice-a-week dialysis, whereas the time averages of the serum creatinine concentration were higher, and those of serum bicarbonate and serum oxalate were not significantly different in the two groups. It is concluded that this combined therapy is a valid alternative to the conventional thrice-a-week hemodialysis and free diet for selected patients and for periods of time whose duration is conditioned by the rate of decline of the residual renal function.
