Background Up to 66% of have anemia at the admission to the intensive care unit. This number increases to 95% after 72 hours of hospitalization in the intensive care unit due to illness and iatrogenic blood loss. Anemia worsens tissue oxygenation, especially in patietns with sepsis or septic shock, who already have blood flow issues. Instead of giving blood transfusions, which can have side effects, we aim to address the root causes of anemia in these patients. Sepsis can cause "inflammatory anemia" and combine with iron deficiency anemia. Current anemia treatments include drugs that stimulate red blood cell production and intravenous iron supplements. Some think that iron supplements can worsen infections by feeding pathogens, but this is not conclusively proven. Since transfused red blood cells (RBC) also contain iron, small doses of intravenous iron might help sepsis patients with iron deficiency.
There is a need for a study on the effects of epoetin alfa and iron derisomaltose on hemoglobin (Hb) levels in sepsis patients.
Hypothesis and Aim Treating anemia in sepsis patients could increase Hb levels and reduce RBC transfusions, improving patient outcomes. This study aims to evaluate the effects of epoetin alfa ± iron derisomaltose on Hb levels and RBC transfusion rates.

Project Description:
Project Title: The use of epoetin alfa and iron derisomaltose in treating anemia in patients with sepsis or septic shock in the ICU: a randomized controlled clinical trial.
Project Acronym: EpoAid
Theoretical Background and Rationale: Up to 66% of patients have anemia at admission to the intensive care unit. Additionally, many patients develop anemia during hospitalization in the intensive care unit due to illness and iatrogenic blood loss for laboratory diagnostics. After 72 hours 95% of intensive care unit patients are anemic. Anemia increases the risk of tissue oxygen deficiency, which is particularly important in sepsis or septic shock patients who may have peripheral perfusion disorders due to infection. Anemia should be treated causally because red blood cell transfusions can lead to adverse effects, including immunomodulation leading to innate immunity suppression, which is particularly significant in critically ill sepsis or septic shock patients. Anemia caused by sepsis is known as inflammatory anemia (AI). Sepsis patients often have mixed anemia, combining features of AI and iron deficiency anemia (IDA) - AI+IDA. Currently available treatments for mixed anemia include erythropoiesis-stimulating agents (ESA) and intravenous iron supplements (e.g., iron derisomaltose). Manufacturers of intravenous iron products contraindicate their use in infections since intravenous iron could theoretically exacerbate infections by stimulating pathogen growth. However, there is no conclusive data on this. Considering that stored red blood cells are also a source of iron that pathogens can use, it seems that fractional doses of intravenous iron could benefit sepsis patients with diagnosed iron deficiency. Additionally, ESA administration could cause functional iron deficiency, where small doses of intravenous iron might also be beneficial.
Attempts to use ESA and intravenous iron in the general ICU population have yielded inconclusive results due to methodological errors. In the IRONMAN study comparing iron carboxymaltose with placebo, no difference in transfusion rates (primary endpoint) was found, but higher Hb levels were observed at hospital discharge in the intervention group (107 vs. 100 g/L). This trial had some methodological flaws: intravenous iron was administered regardless of anemia etiology, red blood cell transfusion decisions were made by clinicians - there was no transfusion algorithm, and the average hospital stay was 11 days - maximal effect of intravenous iron is seen after 3-4 weeks, at least 2 weeks.
Iron deficiency diagnostics in sepsis patients must rely on parameters independent of the systemic inflammatory response since standard iron metabolism parameters (ferritin, transferrin saturation) are not useful here. Severe sepsis was an exclusion criterion in the IRONMAN study. Given the limitations of previous studies and the lack of research on the use of intravenous iron in sepsis patients, it is warranted to conduct a study evaluating the effect of epoetin alfa ± iron derisomaltose on Hb levels in sepsis or septic shock patients.
Hypothesis and Research Aim: Causal treatment of anemia in sepsis or septic shock patients may lead to increased Hb levels and reduced transfusion rates, potentially improving patient outcomes. This study aims to evaluate the effect of epoetin alfa ± iron derisomaltose on one primary and several secondary outcomes.
Materials and Methods: A randomized controlled clinical trial is planned. Blinding will be single due to the color (rusty) of the intervention drug (iron derisomaltose) and problems with complete blinding of the intervention. Randomization will be done using a computer generator of randomized numbers using block of 4. Two hundred patients will be recruited (100 in the experimental group, 100 in the control group). If a study subject starts bleeding or requires surgery (affects Hb levels and transfusion necessity - primary endpoints), the time until this event will be evaluated. Data collected: demographics (gender, age), infection site, length of stay (ICU, hospital), mortality (ICU, hospital, 30 days, 90 days). Blood loss for laboratory diagnostics will be monitored (calculation based on laboratory parameters ordered and test tube used). Pharmacological venous thromboembolism prophylaxis will be used in the experimental and contorol groups: enoxaparin 40 mg x 1 sc in patients with creatinine clearance ≥30 mL/min or dalteparin 5000 IU x 1 sc in patients with creatinine clearance <30 mL/min, and a red blood cell transfusion decision algorithm will be employed.
Experimental group:
epoetin alfa (Binocrit, Sandoz, Poland) given intravenously when Hb <120 g/L, dosed by a study subject weight:
iron derisomaltose (Monover, Pharmacosmos, Denmark) given intravenously at a dose of 0.2g when Hb <120 g/L and RET-He <29.3 pg, administered on days 1, 3, 5, 8, 10, 12
red blood cell transfusion decision based on a proprietary decision algorithm. Binocrit will be stored at 2-8 °C. Before use, the drug will be stored at room temperature for 15 minutes. The drug is packaged in prefilled syringes; it will be mixed with 0.9% sodium chloride to a volume of 20 mL, then injected intravenously as a bolus, followed by a 20 mL 0.9% NaCl sodium chloride bolus to ensure immediate drug entry into the bloodstream. It is crucial to administer the entire dose without loss, as it is the primary intervention drug in this study. Monover is provided in 0.1g ampoules. The drug will be administered at a fixed dose of 0.2g when RET-HE <29.3 pg on the scheduled administration day. The drug will be diluted with 0.9% NaCl to a volume of 50mL and administered in a brown 50mL syringe using an infusion pump at a rate of 60mL/h.
Control Group:
red blood cell transfusion decision based on a proprietary decision algorithm.
Monitored parameters:
Timeline: November 2024 - December 2026
Feasibility: given the number of ICU hospitalizations (approximately 400 per year) and the prevalence of sepsis/septic shock, it will be possible to enroll about 100 patients per year.
