Safety and Efficacy of Ferric Carboxymaltose in the Treatment of Iron Deficiency Anaemia in Patients with Inflammatory Bowel Disease, in Routine Daily Practice
Iron deficiency and iron deficiency anaemia are common complications in inflammatory bowel disease [IBD] patients. Anaemia in IBD is attributable to chronic blood loss and/or impaired iron intake and absorption. International guidelines recommend intravenous iron supplementation in IBD patients, since oral supplements are frequently poorly tolerated and can exacerbate inflammation. Intravenous ferric carboxymaltose [FCM; Ferinject® 50 mg ferric iron[III]/mL suspension] was approved in Europe in 2007 for correction of iron deficiency, and can be administered in single 15-min infusions of up to 1000 mg.
A prospective non-interventional post-marketing study was performed in 101 centres in Germany to assess the efficacy, tolerability, and convenience of Ferinject® in clinical practice in a large cohort of IBD patients. Primary endpoints were haemoglobin [Hb] normalisation or increase ≥2 g/dL [responders], and normalisation of serum ferritin [s-ferritin] and transferrin saturation. Adverse events [AEs], clinical signs/symptoms, and disease activity indices were also analysed.
In all, 224 subjects (127 Crohn's disease [CD]; 97 ulcerative colitis [UC]) were treated. Mean total irondose was 1139 mg [range: 100 mg-4800 mg], with 76.7% of doses between 500 mg and 2000 mg; 63.3% of patients responded, and no adverse drug reactions or drug-attributed serious adverse events [SAEs] or deaths occurred. Mean increases of Hb [10.0 to 12.3 g/dL], ferritin [52 μg/L to 103 μg/L], transferrin saturation [TSAT, 15% to 25%], and s-iron [6.1 to 12.4 μmol/L] were significant [p = 0.0001]. Clinical scores and quality of life improved due to the amelioration of anaemia symptoms.
Ferinject®-therapy was proven to be effective and safe in a large cohort of patients with IBD-associated anaemia in routine practice. Rapid, high-dose application is convenient for physicians and reduces patients' time lost from work.
