This study evaluated whether patients receiving a two-dose regime of epoetin alfa received less allogeneic blood than patients donating autologous blood before primary hip arthroplasty. Consenting patients with a hemoglobin level between 12 and 15 g/dL were randomly assigned to a two-dose administration of epoetin alfa (19 patients) or autologous donation (21 patients). Sixteen percent of the patients in the epoetin alfa group and 52% of the patients in the autologous donation group received transfusions, with a mean volume of 90 cc per patient in the epoetin alfa group and 340 cc in the autologous donation group. Hemoglobin was similar at screening; however, the epoetin alfa group achieved a higher hemoglobin (14.6 g/dL) than the autologous donation group (12.6 g/dL) before surgery. Hemoglobin remained significantly higher in the epoetin alfa group for 3 days after surgery. Administration of two doses of epoetin alfa provided patients with effective and safe reduction of allogeneic blood transfusions and decreased the necessity and difficulty of autologous donation before total hip arthroplasty.

Efficacy and safety of daprodustat in patients on peritoneal dialysis in the ASCEND-D trial.

Background And Hypothesis: Daprodustat, an oral hypoxia-inducible factor prolyl hydroxylase inhibitor, is approved for treatment of anemia in dialysis patients with CKD in some parts of the world. This subgroup analysis examined the efficacy and safety of daprodustat versus darbepoetin alfa in patients with anemia of CKD undergoing peritoneal dialysis (PD).
Methods: ASCEND-D (NCT02879305) was an open-label, Phase 3 trial; patients with CKD were randomized to daprodustat daily and epoetin alfa (HD patients) or darbepoetin alfa (PD patients).
Efficacy of Epoetin Alfa in Managing Symptomatic Anaemia in Low-Risk Myelodysplastic Syndromes: A Retrospective Analysis.

Background Myelodysplastic syndromes (MDS) are clonal myeloid disorders characterised by ineffective haematopoiesis, leading to anaemia that often requires dependence on red blood cell (RBC) transfusions. Epoetin alfa (Eprex®) is now a mainstay in the management of symptomatic anaemia in low-risk MDS patients, reducing transfusion dependence and improving the quality of life in this patient group. Objective This retrospective study aimed to assess the efficacy of epoetin alfa in treating symptomatic anaemia in low-risk MDS patients, focusing on transfusion independence and its relationship with baseline erythropoietin (EPO) levels and haemoglobin (Hb) response.

Background: Luspatercept, an inhibitor of the transforming growth factor beta (TGF-β) pathway, is a novel treatment for anemic patients with lower-risk myelodysplastic syndromes (MDS) with transfusion dependence (TD) who do not respond to erythropoiesis-stimulating agents (ESA) therapy or are not suitable candidates for this treatment. We present real-world experience with luspatercept therapy from two hematology centers in the Czech Republic.
Methods: By January 2024, 54 MDS patients (33 men, 21 women) with a median age of 74 years (range, 55-95) were treated with luspatercept ± ESA at two Charles University hematology centers in Prague and Hradec Králové.
Purpose: We evaluated the efficacy and safety of roxadustat, a first-in-class hypoxia-inducible factor prolyl hydroxylase inhibitor, for chemotherapy-induced anemia (CIA) in patients with nonmyeloid malignancies receiving multicycle treatments of chemotherapy.
Patients And Methods: In this open-label, noninferiority phase III study conducted at 44 sites in China, 159 participants age ≥18 years with CIA nonmyeloid malignancy and CIA were randomly assigned (1:1) to oral roxadustat or subcutaneous recombinant human erythropoietin-α (rHuEPO-α) three times a week for 12 weeks. Roxadustat starting dosages were 100, 120, and 150 mg three times a week for participants weighing 40-<50, 50-60, and >60 kg, respectively.
