Introduction: Epoetin alfa (Eprex®) is a subcutaneous, injectable formulation of short half-life recombinant human erythropoietin (rHuEPO). To current knowledge there are no published studies regarding the stability of rHuEPO once repackaging occurs (r-EPO) for clinical trial purposes. Materials and methods: We assessed EPO concentration in Eprex® and r-EPO syringes at 0, 60, 90, and 120 days after repackaging in polypropylene syringes. R-EPO was administered to 56 patients taking part in a clinical trial in Friedreich Ataxia...

Anaemia is a complication reported in up to 70% of the multiple myeloma patients (MM), with remarkable clinical, cognitive and socio-relational consequences. Anaemia relates to the course of MM, normalizing in patients during remission and reappearing in relapsing/non-responding patients. In a pilot study with 31 patients with MM and transfusion-dependent anaemia, we evaluated the effects of Binocrit (biosimilar epoetin alfa) on transfusions, haemoglobin levels, mental status (mini-mental state evaluation) and the patients' social-relational functioning and quality of life (QoL)...

The increased risks of death and adverse events with erythropoiesis-stimulating agent (ESA) therapy targeting a higher hemoglobin level are established. It is uncertain whether the adverse effects of ESA therapy are related to dose and are mitigated when a fixed low ESA dose is used. We conducted a multicenter, prospective randomized open-label, blinded-endpoint (PROBE) trial to evaluate fixed low versus high dose ESA therapy on patient outcomes. We intended to recruit 2104 hemodialysis patients >18 years with anemia or receiving ESA treated at dialysis clinics in Italy...

BACKGROUND: Many patients with solid tumours or nonmyeloid haematopoietic tumours develop symptomatic anaemia, which has a major impact on quality of life (QoL). The efficacy of erythropoiesis-stimulating agents (ESAs) in improving QoL and reducing blood transfusions has been widely demonstrated. Binocrit® (biosimilar epoetin alfa) is an ESA indicated in the European Union for treating chemotherapy-induced anaemia. The aim of this study was to investigate the effect of Binocrit® on haemoglobin (Hb) levels in anaemic cancer patients in Italian clinical practice...

BACKGROUND: Exogenous replacement of erythropoietin (EPO) by recombinant human EPO has been considered a standard of care for the treatment of anemia in patients with chronic kidney disease for more than 20 years. Genetically engineered biologic proteins derived from human, animal, or microorganism sources are a major area of growth in modern medical care, accounting for one-third of new drug approvals in the past decade. Despite benefit to patients, the use of biologics comes at a significant cost, representing one of the fastest growing segments of strained healthcare budgets around the world...

Spine surgery has been growing rapidly as a neurosurgical operation, with an increase of 220% over a 15-year period. Intraoperative blood transfusion is a major outcome determinant of spine procedures. Various approaches, including pharmacologic and nonpharmacologic therapies, have been tested to decrease both intraoperative and postoperative blood loss. The aim of this systematic review is to report clinical evidence on the relationship between intraoperative blood loss (primary outcome) and on transfusion requirements and postoperative complications (secondary outcomes) in patients undergoing spine surgery...

BACKGROUND: Erythropoiesis-stimulating agents (ESAs) are the mainstay of treatment for renal anemia in chronic kidney disease (CKD) patients. However, the difference in hematopoietic effect between darbepoetin alfa (DA) and continuous erythropoiesis receptor activator (CERA) has remained unclear in non-dialysis CKD patients. Another purpose of this study was to analyze the red blood cells indices under treatment with these two ESAs in ESA-naïve CKD patients. METHODS: This study was designed as a multicenter retrospective observational investigation, and included 61 patients receiving DA (group DA) and 36 patients receiving CERA (group CERA) for at least six months...
