Malabsorption of vitamin B12due to a defect in the ileum has also been noted, and several instances of correction by therapy of this B12malabsorption have been reported in pernicious anemia (2-4) and in idiopathic steatorrhea (5). In this study we evaluated ten successive patients with pernicious anemia, found an ileal defect in absorption of B12in four of them, and corrected the B12malabsorption by B12therapy in three of these four. The true incidence of a gross intestinal defect in absorption of B12in patients...References1.
