Inverse relation between serum IgG concentration and glucose and xylose absorption in Zambian African adults.

Abstract

In three separate investigations in Zambian African adults in Lusaka an inverse association has been shown between serum IgG concentration and either glucose absorption rate from the jejunum (from a 200-mM solution) or xylose absorption (from a 25-g oral load). In developing areas of the world, where serum IgG concentrations are often high, this finding may have widespread nutritional implications.
