Abstract

BACKGROUND: Kidney transplantation may release the patient receiving dialysis therapy in their life style, especially in restriction of dietary intake. However, their renal functions are not enough to take daily diet without any restriction. In Japan, we have neither standard of diet intake for them, nor data to build it.

METHODS: Dietary intake and its satisfaction were surveyed in 62 outpatients who received kidney transplantation in Keio University Hospital using brief-type self-administered diet history questionnaire.

RESULTS: Cross-sectional research was carried out in 2013. Estimated GFR of the object was 42 ± 16 ml/min/1.73 m2. One patient was CKD G1 stage, five in G2, 17 in G3a, 24 in G3b, 14 in G4, and one in G5. Urinary protein was shown in 30 % of patients. Their daily intake was 29 ± 8 kcal/kg of energy, 1.1 ± 0.4 g/kg of protein, 9.9 ± 3.6 g of salt. Protein and salt intakes were over comparing the respective standards for CKD in Japan. The patient who have dissatisfaction for their daily diet was significantly decreased from 79 to 4 % after their kidney transplantation. Attentions to overtake were significantly reduced after kidney transplantation from 56 to 8 % for potassium, 55 to 21 % for salt, 50 to 16 % for protein, 35 to 3 % for calcium/phosphate.

CONCLUSIONS: Changes in daily diet of the patients with dialysis and kidney transplantation were recognized. The patients who received kidney transplantation would take daily diet according to their renal function although they do not have specific standards.
