[Glycoprotein hexoses in feces of infants with lactose intolerance]

A modified method for estimation of total glycoprotein hexoses in feces, based on their measurements in the blood serum, is presented. Sixty-six nursing children with lactose intolerance, breastfed or formula fed, were examined; formula fed babies were kept on mixtures with high and low lactose content. Glycoprotein hexose parameters were as follows (X +/- m): 13.51 +/- 1.93, 12.05 +/- 2.20, and 3.69 +/- 0.47 g/l feces. In control children without lactose intolerance (n = 33) this value was 3.6 +/- 0.79 g/l. Increased glycoprotein excretion is connected with glycocalix and small intestinal enterocyte alteration.
