Iron deficiency and vitamin A deficiency are both reported to predispose to infection morbidity and to mortality. In both situations, however, the data are insufficient to draw firm conclusions, primarily owing to flaws in the design of the studies. To be sure, these are difficult studies to carry out, and the investigators whose reports have been reviewed should be praised rather than adversely criticized for their efforts. In the case of iron deficiency, there is a further complication in interpretation, that is the suggestion that iron deficiency states may be protective and that conditions of iron overload may predispose to infection. These concepts appear to pertain most convincingly to malaria and Yersinia infections, and to situations in which iron dextran is given parenterally to young children in the first few months of life. There are still two few data to suggest that oral iron is harmful and there is no reason at present that it should not be employed for the correction of iron deficiency anemia.

We report a case of ileo-colonic Histoplasmosis without apparent respiratory involvement in a patient who had previously undergone an orthotopic liver transplant (OLT) for primary biliary cholangitis 15 years earlier. The recipient lived in the United Kingdom, a non-endemic region for Histoplasmosis. However, she had previously lived in rural southern Africa prior to her OLT. The patient presented with iron deficiency anaemia, diarrhoea, abdominal pain and progressive weight loss. She reported no previous foreign travel, however, it later became known that following her OLT she had been on holiday to rural southern Africa. On investigation, a mild granulomatous colitis primarily affecting the right colon was identified, that initially improved with mesalazine. Her symptoms worsened after 18 mo with progressive ulceration of her distal small bowel and right colon. Mycobacterial, Yersinia, cytomegalovirus and human immunodeficiency virus infections were excluded and the patient was treated with prednisolone for a working diagnosis of Crohn's disease. Despite some early symptom improvement following steroids, there was subsequent deterioration with the patient developing gram-negative sepsis and multi-organ failure, leading to her death. Post-mortem examination revealed that her ileo-colonic inflammation was caused by Histoplasmosis.
