ferric-carboxymaltose and Heart-Diseases

Anaemia and iron deficiency are frequent in patients scheduled for cardiac surgery. This study assessed whether immediate preoperative treatment could result in reduced perioperative red blood cell (RBC) transfusions and improved outcome.. In this single-centre, randomised, double-blind, parallel-group controlled study, patients undergoing elective cardiac surgery with anaemia (n=253; haemoglobin concentration (Hb) <120 g/L in women and Hb <130 g/L in men) or isolated iron deficiency (n=252; ferritin <100 mcg/L, no anaemia) were enrolled. Participants were randomly assigned (1:1) with the use of a computer-generated range minimisation (allocation probability 0·8) to receive either placebo or combination treatment consisting of a slow infusion of 20 mg/kg ferric carboxymaltose, 40 000 U subcutaneous erythropoietin alpha, 1 mg subcutaneous vitamin B12, and 5 mg oral folic acid or placebo on the day before surgery. Primary outcome was the number of RBC transfusions during the first 7 days. This trial is registered with ClinicalTrials.gov, number NCT02031289.. Between Jan 9, 2014, and July 19, 2017, 1006 patients were enrolled; 505 with anaemia or isolated iron deficiency and 501 in the registry. The combination treatment significantly reduced RBC transfusions from a median of one unit in the placebo group (IQR 0-3) to zero units in the treatment group (0-2, during the first 7 days (odds ratio 0·70 [95% CI 0·50-0·98] for each threshold of number of RBC transfusions, p=0·036) and until postoperative day 90 (p=0·018). Despite fewer RBC units transfused, patients in the treatment group had a higher haemoglobin concentration, higher reticulocyte count, and a higher reticulocyte haemoglobin content during the first 7 days (p≤0·001). Combined allogeneic transfusions were less in the treatment group (0 [IQR 0-2]) versus the placebo group (1 [0-3]) during the first 7 days (p=0·038) and until postoperative day 90 (p=0·019). 73 (30%) serious adverse events were reported in the treatment group group versus 79 (33%) in the placebo group.. An ultra-short-term combination treatment with intravenous iron, subcutaneous erythropoietin alpha, vitamin B12, and oral folic acid reduced RBC and total allogeneic blood product transfusions in patients with preoperative anaemia or isolated iron deficiency undergoing elective cardiac surgery..

Many patients receiving oral iron for iron deficiency anemia (IDA) cannot tolerate or fail to respond to therapy, and existing intravenous (IV) iron formulations often require repeated administrations. Ferric carboxymaltose (FCM), a nondextran IV formulation, permits larger single doses.. We evaluated FCM versus oral iron in IDA patients. After 14 days of oral iron, 507 participants responding inadequately to oral iron (hemoglobin [Hb] increase <1 g/dL; Cohort 1) were assigned to Group A (two doses of FCM, 750 mg, 1 week apart) or Group B (oral iron, 325 mg, 3 × day for 14 additional days). Also, 504 subjects not appropriate for oral iron (Cohort 2) were assigned to Group C (FCM as above) or Group D (standard-of-care IV iron). The primary efficacy endpoint was change to highest observed Hb from baseline to Day 35. The composite safety endpoint included all-cause mortality, nonfatal myocardial infarction, nonfatal stroke, unstable angina, heart failure, arrhythmias, and hyper- or hypotensive events.. Mean (± standard deviation [SD]) Hb increase was significantly greater in Group A-FCM than Group B-oral iron: 1.57 (±1.19) g/dL versus 0.80 (±0.80) g/dL (p = 0.001). Post hoc comparison of Group C-FCM and Group D-IV standard of care also demonstrated significant mean (±SD) increase in Hb from baseline to highest value by Day 35 in Group C versus Group D: 2.90 (±1.64) g/dL versus 2.16 (±1.25) g/dL (p = 0.001). Safety endpoints occurred in 17 of 499 (3.4%) participants receiving FCM versus 16 of 498 (3.2%) in comparator groups.. Two 750-mg FCM infusions are safe and superior to oral iron in increasing Hb levels in IDA patients with inadequate oral iron response.
