Background: Dietary recommendations for chronic kidney disease advise 3 to 6 g/day of dietary salt intake. We evaluated current adherence to dietary recommendations for CKD and correlation between sodium intake and urine protein in kidney transplant recipients in maintenance phase.
Methods: Of 358 kidney transplant recipients who were attending our hospital, 320 recipients with complete data served as subjects. Estimated daily oral intakes of salt were calculated from 24-h urinary excretion of sodium.
Results: The present study included 185 male and 135 female recipients. The mean age, posttransplant years, and 24-h urinary excretion of protein were 53.1 years, 12.7 years, and 330 mg/d, respectively. Estimated daily salt intake was 9.04 g/d. Only 20.3% of the patients consumed < 6 g/d of sodium intake. The 24-h urinary protein excretion of the daily salt intake-adherent group (< 6 g/d) was significantly less than that of non-adherent group (≥ 6 g/d) (adherent vs. non-adherent, 220 mg vs. 360mg, respectively; p=0.0004). There was a positive significant relationship between salt intake and 24-h urinary excretion of protein (Spearman's correlation, p < 0.0001).
Conclusions: The adherence rate to dietary recommendations for CKD was low in kidney transplant recipients. Lower salt diet may reduce urine protein excretion in kidney transplant recipients.
