In chronic renal failure (CRF) patients with a reduced protein intake, if the patients' energy intake could be estimated on the basis of biochemical data together with protein intake, it would be easier to provide them with adequate dietary treatment. Thus, from the relationship among the normalized protein catabolic rate (nPCR) and the intrinsic creatinine generation rate (%GCr) both calculated on the basis of 24-hr urine creatinine, as well as the daily dietary energy intake evaluated by a skilled nutritionist, we devised the following equation to estimate the amount of dietary energy deficiency (delta E) whose supplementation increases the %GCr of patients on protein-restricted dietary regimens to the target level (i.e., the dietary energy deficient amount). This was done by taking the %GCr of average nondiabetic hemodialysis patients of the same age and sex as a temporal target level: delta E = [31.22 - 1.97 (%GCr)0.6]/(nPCR)0.15. In order to examine the clinical usefulness of this equation, the daily dietary energy deficient amount calculated by the equation was supplemented with protein-free jelly. As a result, the %GCr increased from approximately three-fourths of the target level to the target level within 4 months.
