Filter by:Prospective single-center observational study assessing prevalence of FID (Laboratory work-up) and Quality of Life (Questionnaire) in adult patients with oncological and with haematological malignancies within four weeks prior to disease-directed therapy.
The purpose of this trial is to determine if the combination of goal directed iron supplementation and hepcidin mitigation can safely eliminate both the serum and bone marrow iron debt of anemic, critically ill trauma patients with functional iron deficiency.
Critically ill surgical patients are observed to have a functional iron deficiency which contributes to anemia, iron-deficient erythropoiesis, and an increased red blood cell transfusion requirement. Previously, iron supplementation has been studied in this population with the administration of enteral ferrous sulfate and intravenous iron sucrose but without robust results in resolving serum and bone marrow iron debts. Ferric carboxymaltose (FCM) is novel iron-containing complex that allows for the administration of a large dose of iron over a short infusion period to allow for sustained delivery of iron to target tissues with minimal hypersensitivity reactions. While there has been reported increased efficacy and comparable safety of FCM when compared to iron sucrose in the outpatient setting, there is no data comparing these two medications in surgical critical illness. The aim of this pilot trial is to compare two novel dosing schemes of these medications for treatment of functional iron deficiency in surgical ICU patients. The investigators hypothesize that iron supplementation with FCM, as compared to both iron sucrose and placebo, is more effective and equally safe for replacing the serum iron debt.
Anaemia is a common complication of Chronic Kidney Disease (CKD) the management of which has been aided by the use of synthetic recombinant human erythropoietin therapy (r-HuEPO). This red cell stimulating agent creates the further complication of Functional Iron Deficiency (FID) where, despite normal iron stores, patients fail to respond to therapy as they do not possess enough available iron to meet the demand of increased red cell production. Effective response to r-HuEPO therapy depends on an appropriate monitoring of 'available' iron levels. Previous research into the clinical utility of testing for reticulated haemoglobin concentrations (Ret He) instead of Serum Ferritin and Transferrin Saturation analysis has indicated an advantage as an iron deficient prognostic marker however, further knowledge is required on the use of this new laboratory test (RetHe) to predict Functional Iron Deficiency (FID) level and to study it's relationship with responses to therapy. This proposed study aims to estimate a local working Normal (non deficient) and Iron Deficient Reticulated Haemoglobin Content (RET He) reference range from surplus anonamous samples. Routine monthly blood samples from Pre Dialysis and Haemodialysis patients will be used to evaluate the sensitivity and specificity of the RET He test compared to current laboratory tests and investigate its predictive ability for Functional Iron Deficiency in these patients. Studying , measuring and statistically analysing the change in the RET He parameters in Haemodialysis and Pre Dialysis patients over 3 months will look for evidence of a direct relationship between RET He values and the patients response to therapy. The data will be used to provide a predictive picture of what levels of RET He indicate Functional Iron Deficiency. The introduction of this test (RetHe) may provide clinicians with a one sample/one test control over iron therapies and ensure the patient gets the most benefit from erythropoietin therapy.
The purpose of the study is to define laboratory parameters which are best suited to diagnose functional iron deficiency. Functional iron deficiency is a condition where - due to the lack of iron bioavailability - the patient suffers from symptoms such as fatigue and weakness, or his/her capacity to produce red blood cells is reduced.
