Abstract

In order to investigate methodologic and clinical aspects of resting energy expenditure (REE) in chronical renal failure (CRF) 66 non dialyzed CFR patients (34 men + 32 women 59 ± 14 yrs) and 61 normal subjects (32 men + 29 women; 54 ± 17 yrs) were submitted to indirect calorimetry following standard protocol. REEs in CFR pts were then compared with predicted values (BEE: Harris-Benedict equation) and referred to glomerular filtration rate (GFR). On the basis of REE total energy expenditure was calculated (E(Kg) = REE(Kg) x 1.4) and compared with recommended total energy expenditure (E(Kg) pr. = 35 Kcal/kg/24 hrs) to maintain neutral balance in most chronically uremic patients. Our results show that REE was 20.1 ± 2.75 Kcal/kg/24 hrs in CRF men vs 19.5 ± 2.1 Kcal/kg/24 hrs of male control group (ns) and 18.4 ± 1.8 Kcal/kg/24 hrs in CRF women vs 17.7 ± 2.1 Kcal/kg 24 hrs of normal women (ns). Moreover there was a good correlation between REE and BEE (r = 0.76; p <0.01) but in 40.9% CRF patients REE values were out of 90-110% BEE. No correlation was found between REE and CRF finally E(Kg) pr. was higher by mean 20% than E(Kg) in 95% of CRF patients. In conclusion a) pre-dialytic CRF pts have normal energy production; b) BEE can not satisfactory predict REE in CRF patients; c) energy production does not correlate with renal impairment; d) recommended total energy expenditure overstimates total calculated caloric needs; moreover at present this point offers only a theoric mean.
