Filter by:BACKGROUND Anemia and iron deficiency are highly prevalent in cardiac surgery patients. Both conditions may adversely affect postoperative rehabilitation. At hospital discharge, anemia is almost invariably present due to perioperative blood loss and frequent blood sampling. Two previous analyses demonstrated a prevalence of anemia early after coronary artery bypass grafting (CABG) of 94% and 98%, respectively. Almost half of CABG patients had persistent anemia two months after surgery. Postoperative anemia may result in debilitating symptoms, like dyspnoea, fatigue and poor exercise tolerance, and is associated with an increased likelihood of cardiovascular events and death after cardiac surgery. Mild to moderate anemia is commonly corrected with oral iron supplements. Oral iron is however poorly absorbed in patients with chronic diseases, and about 40% of patients suffer from debilitating gastrointestinal side-effects. As iron stores are frequently reduced or depleted after cardiac surgery, treatment with oral iron supplements may take several months. In patients with chronic heart failure (CHF), iron deficiency is associated with reduced exercise capacity, quality of life and survival even in the absence of anemia. Several large randomised trials demonstrated that treatment with intravenous iron improved clinical symptoms, exercise capacity and quality of life of CHF patients. RATIONALE It is desirable to replenish body iron stores rapidly after cardiac surgery with the aim to effectively correct anemia, optimize exercise tolerance and improve patient wellbeing. Modern intravenous iron formulations permit fast replenishment of body iron stores and have emerged as potential alternatives to oral iron. These formulations are well-tolerated and have become an established therapeutic option in anemic patients with reduced intestinal iron absorption. Several studies have demonstrated the efficacy of intravenous iron for the treatment of anemia following major non-cardiac surgery. Data regarding the efficacy of intravenous iron in cardiac surgery, however, are conflicting. HYPOTHESIS Single-dose intravenous iron therapy with ferric derisomaltose/iron isomaltoside is superior to oral iron supplementation for the correction of anemia following cardiac surgery. Moreover, single-dose intravenous iron therapy with ferric derisomaltose/iron isomaltoside results in a greater postoperative exercise capacity, an improved quality of life and less fatigue.
This study is a pilot, open-label, single-arm study to evaluate the effect of the sickle cell medication voxelotor on exercise capacity, as measured by cardiopulmonary exercise testing (CPET) in patients 12 years of age and older with sickle cell anemia (SCA).
Child undernutrition is largely attributed to inadequate nutrition including micronutrient deficiency. Undernutrition is prevalent among indigenous children as compared to the general population. This cluster randomized controlled trial aimed to determine the effect of multiple-micronutrients supplement (MMS) on growth and iron status of Orang Asli (indigenous group in Peninsular Malaysia) young children (6 to 24 months) in Selangor. MMS is a blend of 15 micronutrients in powder form that can be used for home fortification of foods for young children. A total of 98 children recruited in this study with 49 children randomly assigned for each intervention (IG) and control group (CG). At baseline, all children were normal in weight-for-age (WAZ>-2SD), length-for-age (LAZ>-2SD), weight-for-length (WLZ>-2SD) and blood haemoglobin (>11g/dL). IG was supplemented with three sachets of MMS each week i.e. every other day for 12 months and received health and nutrition advice. CG only received health and nutrition advice. Both groups were assessed for body weight, length and dietary intake at baseline, month 3, 6, 9, 12 of intervention, and 3 months post intervention. Blood haemoglobin was assessed at baseline, month-12 of intervention and 3 months post intervention. Compliance to MMS was measured in IG. The primary outcomes were weight, length, WAZ, LAZ, WLZ and haemoglobin, while the secondary outcome was dietary intake. The independence sample t-test and the chi-square test were used to determine the difference in the baseline variables between the groups. ANOVA using General Linear Model (GLM) for repeated measures was performed to determine the difference in the growth measures z scores, haemoglobin, energy, nutrients and food group within and between the groups over the period of the study. Per protocol analysis was performed. This study hypothesized that there were significant differences in the changes (before and after MMS intervention) related to growth [(weight-for-age (WAZ), length-for-age (LAZ) and weight-for-length (WLZ)]; iron status (haemoglobin concentration); and dietary intake (energy, nutrients and food group intakes) between intervention and control groups.
This study was a multi-center, randomized, open-label, active comparator-controlled, parallel group study. The purpose of this Phase 3 study in PNH patients presenting with residual anemia despite treatment with anti-C5 antibody, was to determine whether iptacopan is efficacious and safe for the treatment of PNH through demonstration of superiority of iptacopan compared to anti-C5 antibody treatment.
To assess the safety and effectiveness of PBF-1681 for the treatment of Iron Deficiency Anemia in patients with Non-Dialysis Dependent Chronic Kidney Disease.
Erythroferrone (ERFE) is a recently identified iron-regulatory hormone that couples iron homeostasis to erythropoiesis but at this time there are no human data on this hormone in pregnant women and their neonates. The investigators hypothesize that ERFE is a sensitive biomarker of iron deficiency and anemia in pregnancy and neonates, and that it mediates the feedback mechanism to correct iron deficiency and anemia. To address this research gap, the investigators will measure ERFE in maternal serum, umbilical cord serum and placental tissue using an existing biospecimen archive.
Anemia is common in oncology. Up to three-quarters of cancer patients are exposed to an episode of anemia. In oncology surgery, perioperative bleeding is a major risk factor for anemia. Indeed, 13 to 40% of patients are transfused in perioperative oncologic surgery. There is an association between anemia and prognosis. Several epidemiological studies have shown a strong association between anemia and altered quality of life. In oncology cohort studies, anemic patients had a significantly lower quality of life compared to patients without anemia. In non-cardiac surgery, preoperative anaemia was significantly associated with post-operative mortality. There is also an association between preoperative anaemia and the occurrence of post-operative complications. In oncology surgery, cohort studies conducted in colorectal surgery and neurosurgery found an association between the occurrence of perioperative anemia and post-operative morbidity and mortality. The optimal transfusion strategy is unknown in oncology patients. Several multicentre randomised trials, conducted in resuscitation patients or in perioperative settings, have compared a "restrictive" to a "liberal" transfusion strategy. These studies did not show a superiority of one strategy over another on patient outcomes but a lower exposure to red blood cell concentrates in patients transfused with the restrictive transfusion strategy. Thus, the French High Authority for Health (HAS) has adopted a haemoglobin level of 7 g/dl as the transfusion threshold for any transfusion of red blood cell concentrate carried out in the operating theatre and in intensive care in the absence of special cases such as the presence of acute coronary syndrome. For oncology patients, no recommendation could be made due to the lack of evidence-based literature and the optimal transfusion strategy for these patients remains unknown. Only 2 monocentric trials performed in oncology (critical care and perioperative) suggest a benefit of a liberal strategy (transfusion for a haemoglobin level < 9 g/dl) on the short-term vital prognosis, but these studies suffer from numerous limitations leaving the question unresolved. Before conducting a large phase III trial, a pilot study is needed to validate the methodology of this multicentre clinical trial and to assess its feasibility.
The primary objective of this clinical investigation is to report on the repeatability and reproducibility of SpHb measurements from Rad-67 devices and DCI Mini sensors used to screen prospective blood donors at a donation center.
The purpose of this study is to assess the safety and effectiveness of roxadustat dosing regimens among hemodialysis participants converted from erythropoiesis stimulating agent (ESA) therapy or who are ESA-naïve.
