[Hypophosphatemia following the administration of intravenous iron formulations: A case report and literature review]. / Hypophosphatémie et fer injectable : à propos d'un cas et revue de la littérature.

Iron deficiency and iron-deficiency anemia are common medical conditions. Management of the etiology and iron supplementation are both necessary to treat this condition. Use of intravenous iron preparations is increasing due to its advantages over oral iron. Indeed, the total dose required can be provided in a single infusion, and it is more effective and increases hemoglobin levels more quickly than oral iron. Hypophosphatemia, sometimes severe, following intravenous iron administration, has been described in literature these past years, in particular with ferric carboxymaltose. We report here a case of severe hypophosphatemia with ferric carboxymaltose and carry out a literature review to determine the incidence of hypophosphatemia and to precise its clinical presentation, its pathophysiological mechanisms and its treatment. We found that hypophosphatemia is frequent with ferric carboxymaltose. Most of the time, there are no clinical manifestations, but cases of symptomatic osteomalacia have been described. Duration of hypophosphatemia is variable, from a few weeks to several months in case of prolonged administration. Hypophosphatemia owing to renal phosphate wasting is caused by an increase in intact fibroblast growth factor 23 (FGF-23) levels. However, the mechanism of ferric carboxymaltose- induced increase in intact FGF-23 is still unknown.

[Treatment of iron deficiency anemia during pregnancy with oral iron: State of practice among midwives]. / Traitement par fer oral de l'anémie ferriprive lors de la grossesse : état des pratiques chez les sages-femmes.

OBJECTIVES: Iron deficiency anemia represents a public health issue which is usually managed by midwives. Because it is associated with maternal and fetal risks, a treatment is warranted. Oral iron represents the main option for treating this condition. Despite the existence of national and international guidelines no consensus about its modality of use has emerged so far. The primary objective of this study was to analyze midwives'practice with regards to iron deficiency anemia treatment using oral iron formulations. METHODS: We conducted an observational and descriptive cross-sectional in a sample of midwives from the Gironde administrative region using a questionnaire. RESULTS: We obtained 85 questionnaires from midwives working in private or public health facilities. Doses of iron and duration of treatment seem insufficient for a majority of responders. Folic acid and vitamin C are often associated with oral iron. Most midwives assess the efficacy of oral iron at one month with hemoglobin and ferritin levels. A significant fraction of these midwives shares similar practices which are in good accordance with the literature such as patient counselling with regards to drug intake, management of gastrointestinal side effects and inefficacity of oral iron. Noticeably, some of these midwives don't follow any guidelines. CONCLUSION: The majority of participants demonstrated practices in accordance with various national guidelines although no precise therapeutic algorithm is available as reference. Larger studies on the management of iron deficiency anemia in pregnancy by health professionals and harmonization of practices are necessary.
