Taurine intake and excretion in patients undergoing long term enteral nutrition.
The purpose of this study was to investigate whether serum concentration and urinary excretion of taurine are influenced by marginal taurine intake. Twenty one male patients (75 to 95 years old), suffering from coronary heart disease, multiple cerebral infarction, cancer, subdural hematoma or respiratory failure were grouped according to duration of tube feeding (group one, 5.9 +/- 2.9; group two, 14.8 +/- 2.3; group three 48.0 +/- 22.7, mean +/- SD, months). The mean intake of taurine was 347.0 +/- 25.6, 339.8 +/- 25.6 and 337.1 +/- 259 micromol/day (mean +/- SEM) in group one, two and three, respectively. The fasting serum taurine levels were 106.5 +/- 9.6, 95.0 +/- 9.9 and 56.8 +/- 11.0 micromol/L (mean +/- SEM) in group one, two and three, respectively. Taurine level in group three patients was significantly lower than that of group one and two (p<0.05). The twenty-four hour urinary taurine excretion was 776.1 +/- 176.7, 782.4 +/- 245.3 and 388.3 +/- 169.3 micromol/day (mean +/- SEM) in group one, two and three, respectively. These results suggest that marginal taurine intake in patients receiving long term tube feeding could result in taurine deficiency.
