Folic acid absorption in regional enteritis.
The authors have investigated intestinal absorption of folic acid by jejunal perfusion with a triple lumen tube in five subjects with regional enteritis. The subjects' intestinal disabilities ranged from terminal ileitis to short bowel syndrome. Two had steatorrhea and two had low serum folate levels. Absorption of pteroylglutamic acid was normal in all five. This suggests that folic acid deficiency, common in this disorder, is largely caused by malnutrition, not malabsorption.
