ferlixit and Heart-Failure

Patients with heart failure (HF) with iron deficiency (ID) have worse New York Heart Association class and are at a higher risk of recurrent hospitalizations. Intravenous (IV) iron has been shown to improve exercise ability and reduce hospitalizations. IV sodium ferric gluconate complex (SFGC) has been found to be safe and affordable but has not been studied in this population in a randomized trial. This was a prospective, single-blind, investigator-initiated, randomized controlled trial. Patients admitted for acute heart failure with ID were randomly assigned 1:1 to receive IV SFGC on top of optimal medical treatment. The primary outcome was the change in the 6-minute walk test (6MWT) from baseline to 3 and 6 months. Between September 2019 and May 2021, 34 patients were randomized. 19 patients (55%) were randomized to the treatment arm receiving 125 mg of IV SFGC per day for 3-5 days. COVID-19 was a major barrier to the implementation of the study follow-up protocol, which caused the study to end early. Both groups of patients had similar clinical characteristics, comorbidities, median left ventricular ejection fraction, and rate of death and readmissions due to HF. A higher level of NT-proBNP was observed in patients treated with IV iron (7902 pg/mL vs. 3158, P = 0.04). There was no difference in 6MWT change between groups at 3 months (improvement of 21.6 vs. 24.1 meters) or 6 months (-5 meters vs. 46 meters). In conclusion, IV SFGC-treated patients had a comparable 6-minute walk at 3 and 6 months despite suffering from more severe HF with higher baseline NT-proBNP (NCT04063033).

To assess the short-term efficacy and safety of an accelerated intravenous iron regimen in hospitalized patients with heart failure and iron deficiency.. Prospective, single-arm, open-label study.. Large tertiary care medical center.. Thirteen patients with New York Heart Association class III-IV heart failure, anemia (hemoglobin level ≤ 12.0 g/dl), and iron deficiency (ferritin level < 100 ng/ml, or ferritin level of 100-300 ng/ml with transferrin saturation < 20%) hospitalized between April 2011 and December 2013.. All patients received sodium ferric gluconate 250 mg in 100 ml of normal saline intravenously over 2 hours twice/day until the iron deficit was corrected or the patient was discharged.. Changes in hematologic parameters were assessed at 1-4 weeks after therapy. Patients received a mean ± standard deviation (SD) total iron dose of 1269 ± 207 mg over 3.4 ± 1.0 days. After a mean ± SD follow-up of 13.1 ± 5.6 days, intravenous iron increased hemoglobin level by 1.2 g/dl (95% confidence interval [CI] 0.45-1.9, p=0.005), ferritin level by 364.2 ng/ml (95% CI 129.7-598.7, p=0.007), and transferrin saturation by 10.5% (95% CI 6.5-14.6%, p<0.001). Changes in hemoglobin level did not correlate with volume status, as determined by differences in body weight. No significant changes in blood pressure or heart rate were observed. Adverse events were few and minor in severity (e.g., nausea, constipation, and abdominal discomfort).. An accelerated intravenous iron regimen improved hematologic parameters and was well tolerated in hospitalized patients with advanced heart failure. A randomized multicenter trial comparing this regimen with placebo is warranted.

The ACC/AHA heart failure (HF) guidelines include a class IIb recommendation for intravenous (IV) iron replacement in patients with iron deficiency and New York Heart Association class II or III to improve functional status and quality of life. Several studies have addressed the use of IV iron formulations such as ferric carboxymaltose or iron sucrose in HF population; however, few studies focused on sodium ferric gluconate complex (SFGC).. To assess the safety and effectiveness of an IV SFGC administration protocol in patients hospitalized with HF.. A retrospective cohort study was conducted. We included patients admitted to the HF service from September 2017 to March 2018. The primary outcome was the frequency of adverse reactions. The secondary outcome was the odds of HF readmissions between the 2 groups (IV SFGC vs. control).. Of the 123 patients, 70 received IV iron (SFGC group) and 53 did not receive IV iron (control group). Five (7%) patients of the 70 in the SFGC group experienced adverse events, which included hypotension (n = 2, 2.8%), fever (n = 2, 2.8%) and myalgia (n = 2, 2.8%). Nine (12.8%) and 18 (25.7%) were readmitted within 30 days and 6 months respectively. In the control arm, 5 (9.4%) and 14 (26.4%) were admitted within 30 days and 6 months respectively. The odds of HF readmission at 30 days [OR 1.4 (95% CI: 0.45, 4.5)] and at 6 months [OR 0.96 (95% CI: 0.43, 2.2)] were similar in those who did not receive IV iron compared to those who received IV iron.. Sodium ferric gluconate complex given at an accelerated dosing schedule appears to provide a more efficient means to prescribe IV iron in the inpatient setting and is safe with a low frequency of hypotension, fevers, and myalgias.

Studies have reported conflicting findings on the infection risk posed by intravenous iron supplementation among hemodialysis (HD) patients. We used a novel study design to assess associations between intravenous iron and infectious diseases.. Patients initiating HD between 1998 and 2008 were extracted from Taiwan's National Health Insurance Research Database. Their first infectious disease in the period between 1.5 years after dialysis initiation and 2010 was identified and defined as the index date. Through the case-crossover design, the odds of exposure to intravenous iron within the 1-month period immediately preceding the index date (i.e., the case period) were compared with iron exposure in three different matched control periods for the same enrollee, thus possibly reducing some unmeasured confounders.. A total of 1410 patients who met our enrollment criteria were extracted from incident HD patients. The odds of intravenous iron exposure during the case period versus total control periods exhibited no significant difference (odds ratio: 1.000, 95% confidence interval: 0.75-1.33). In subgroup analyses, this association remained nonsignificant across patients with diabetes mellitus, heart failure, chronic lung disease, venous catheter for HD, and higher iron load.. We found that intravenous iron supplementation did not increase short-term infection risk among HD patients.
