Intestinal lactase deficiency and diarrhea in adults

  • Arthur P. Klotz
Article

Conclusions

Two cases of adult lactose intolerance are reported. The absence and severe deficiency of the enzyme B-galactosidase resulting in the syndrome was confirmed by both histochemical staining and paper chromatography.

Methods to determine intestinal enzyme activity by peroral biopsy open a new avenue of investigation of absorption in the gastrointestinal tract and of patients with unexplained diarrhea.

Such cases narrow the concept of food “allergies” often loosely employed for conditions unrelated to immune phenomena.
