Studies in primary hypomagnesaemia: evidence for defective carrier-mediated small intestinal transport of magnesium.

A 4 year old male with primary hypomagnesaemia was studied using balance and steady-state perfusion techniques. Magnesium balance was negative and could be accounted for by increased faecal losses, renal conservation being normal; calcium balance was normal. After oral magnesium therapy magnesium balance became positive. The perfusion studies demonstrated… (More)
