title: Intravenous iron in digestive diseases: a clinical (re)view.
abstract: Intravenous iron has been considered dangerous by many clinicians. In the last two decades, considerable experience has been gained with new formulations in different clinical settings. Data from clinical trials, observational studies, and postmarketing surveillance studies demonstrate that intravenous iron is safe and effective to treat iron deficiency and iron deficiency anaemia. Iron deficiency is particularly common in many digestive diseases: oral iron often fails while transfusions are not without considerable risks. In particular, in inflammatory bowel diseases, there is enough evidence to recommend intravenous iron in moderate-to-severe iron deficiency anaemia, in intolerance to oral iron, and in patients needing quick recovery (pre-operative setting). New formulations make treatment even easier and more convenient. Recent guidelines are available for inflammatory bowel diseases, and new guidelines in acute and chronic gastrointestinal bleeding are needed.
