Septicemia due to Yersinia enterocolitica in a hemodialyzed, iron-depleted patient receiving omeprazole and oral iron supplementation.

Septicemia occurred in a long-term hemodialysis patient on oral iron supplementation who had been treated for esophageal ulcer by omeprazole, an ulcer-healing drug. Yersinia enterocolitica serotype 0:3 was recovered from blood cultures. A raised intraintestinal pH and an increased intraluminal iron load may have been contributing factors for the enhanced proliferation and generalized infection of Y enterocolitica.
