Absorption of D-xylose in full term newborns adequate for gestational age: prospective study up to third month.

Studies of the D-xylose absorption capacity in newborns are scarce and the results reported are controversial. We evaluated the xylose absorption in full term newborns adequate for gestational age in the first days of life and prospectively up to the third month. D-xylosemia values of the first and second hours at birth and at 3-5 days are significantly lower than on the 15th day at one month and at three months.
