Described herein are methods for treating patients with iron-deficiency anemia (IDA), comprising administering ferric citrate to such patients. In certain aspects, the patients treated for iron-deficiency anemia have a gastrointestinal disorder, such as inflammatory bowel disease, inflammatory bowel syndrome, Crohn’s disease, microscopic colitis (such as collagenous or lymphocytic colitis), or chemically-induced colitis (e.g., NSAID (nonsteroidal anti-inflammatory drug)-induced colitis). In certain aspects, the patients treated for iron-deficiency anemia have blood loss associated with childbirth, menstruation or infection. In some aspects, the patients treated for iron-deficiency anemia have insufficient dietary intake of iron and/or insufficient absorption of iron.本文闡述治療患有缺鐵性貧血(IDA)之患者之方法,其包含向該等患者投與檸檬酸鐵。在某些態樣中,針對缺鐵性貧血進行治療之該等患者患有胃腸道病症,例如發炎性腸病、發炎性腸症候群、克隆氏病(Crohn’s disease)、顯微鏡下結腸炎(例如膠原性或淋巴球性結腸炎)或化學誘導之結腸炎(例如NSAID(非類固醇抗發炎藥物)誘導之結腸炎)。在某些態樣中,針對缺鐵性貧血進行治療之該等患者具有與分娩、月經或感染相關之失血。在一些態樣中,針對缺鐵性貧血進行治療之該等患者具有鐵飲食攝取不足及/或鐵吸收不足。
