AI Article Synopsis

  • Iron deficiency is a significant issue for heart failure patients with left ventricular assist devices (LVAD), with prevalence rates between 40% and 82% found in studies.
  • IV iron treatment is generally safe and can correct iron deficiency, but it is unclear how this affects survival or exercise capacity post-implant.
  • Accurate diagnosis of iron deficiency may be challenging, suggesting the need for more rigorous clinical trials to understand its impact in LVAD patients better.

Article Abstract

Iron deficiency is a common and independent predictor of adverse outcomes in patients with heart failure. The implications of iron deficiency in patients implanted with a left ventricular assist device (LVAD) are less established. This review recaps data on the prevalence, characteristics and impact of Iron deficiency in the LVAD population. A systematic search yielded eight studies involving 517 LVAD patients, with iron deficiency prevalence ranging from 40% to 82%. IV iron repletion was not associated with adverse events and effectively resolved iron deficiency in most patients. However, the effects of iron deficiency and iron repletion on post-implant survival and exercise capacity remain unknown. Although iron deficiency is highly prevalent in LVAD patients, its true prevalence and adverse effects may be misestimated due to inexact diagnostic criteria. Future randomised controlled trials on IV iron treatment in LVAD patients are warranted to clarify the significance of this common comorbidity.

One of the biggest public health problems globally is that of iron deficiency anemia. The present research aimed to determine the effect of prebiotics along with iron fortification on iron biomarkers in female anemic rats as some evidence suggests that prebiotics convert increase the solubility of iron, thereby enhancing its absorption. A total of 126 Sprague Dawley rats were fed with sixteen different types of fortified feed containing prebiotics (Inulin + Galacto Oligosaccharides) and Iron Fortificants (Sodium Ferric Ethylenediaminetetraacetate + Ferrous Sulphate).

Background: The impact of iron deficiency on COPD morbidity independent of anemia status is unknown. Understanding the association between iron deficiency, anemia status, and risk of hospitalization in COPD may inform an approach to these comorbidities.

Study Design And Methods: Adults ≥40 years from the Johns Hopkins COPD Precision Medicine Center of Excellence data repository with an outpatient iron profile and 1 year of subsequent follow-up time were included in the study.

In Japan, most HbA1c measurements by enzymatic assays or immunoassays represent the HbA1c levels in the blood cell fraction obtained after centrifugation of the blood samples. The present study investigated that the blood cell enzymatic HbA1c assay (EA-HbA1c) was compared with whole blood HbA1c in patients with iron deficiency anemia (IDA). Study 1: EA-HbA1c levels using blood cell samples (blood cell EA-HbA1c) and high-performance liquid chromatography (HPLC)-HbA1c levels using whole blood samples (whole blood HPLC-HbA1c) were measured in 15 IDA patients with Hb < 8 g/dL and transferrin saturation (TSAT) < 20%, and the correlations between the blood cell EA-HbA1c/whole blood HPLC-HbA1c ratio (%) and various IDA indicators [mean corpuscular hemoglobin concentration (MCHC), TSAT, and logarithmically transformed ferritin (log-FER)] were examined.

Iron improves the antiviral activity of NK cells.

Natural killer (NK) cells are innate immune cells that play a crucial role as a first line of defense against viral infections and tumor development. Iron is an essential nutrient for immune cells, but it can also pose biochemical risks such as the production of reactive oxygen species. The importance of iron for the NK cell function has gained increasing recognition.

Aims: While it is widely accepted that intravenous (IV) iron improves functional capacity, symptoms, and cardiovascular outcomes in patients with heart failure (HF) with reduced ejection fraction (HFrEF) diagnosed with iron deficiency (ID), three recently published cardiovascular outcome trials (AFFIRM-AHF, IRONMAN and HEART-FID) of IV iron supplementation in HF failed to demonstrate a significant benefit on their respective primary endpoints. Dosing of IV iron after the initial correction of baseline ID - by design or as a result of trial circumstances - was relatively low (i.e.
