Pure red cell aplasia is a rare condition associated with the use of recombinant human erythropoietin preparations. It has predominantly been associated with the subcutaneous use of a particular epoetin-α product, Eprex, and is rarely associated with intravenous use or with other commercially available products. Only a few cases of pure red cell aplasia secondary to epoetin-β have been reported. On account of its rarity, the condition can often be missed on initial presentation, leading to unnecessary investigations and delayed diagnosis...

Erythropoietin (EPO) and thrombopoietin (TPO) plays a major role in the regulation of hematopoietic development. Though, blood transfusion was the most widely used method to treat low blood count, over the years with advancements in recombinant technology and drug designing, the EPO and TPO mimetics are dominating the therapeutics industry. On the other hand, the recombinant human EPO and TPO are associated either with reduced half-life or immune reactions. The restoration of alternate medicine in recent years has the hope to overcome limitations associated with recombinant technology, to treat various disorder including blood diseases, with low to no side effects...

Progression of anemia in patients with chronic kidney disease (CKD) is associated with an increased risk of death and hospitalization. It is not sufficiently clear whether treating renal anemia with recombinant human erythropoietin (rHuEPO) has a beneficial effect on early survival after hemodialysis (HD) initiation in patients with CKD. The study was an open-label multicenter retrospective cohort study to evaluate the relationship between rHuEPO treatment and early survival after HD initiation in patients with CKD...

Erythroid progenitors that respond to erythropoietin (Epo) are present in the liver of adult Xenopus laevis. However, cells responding to Epo in the larval liver and through the metamorphosis period under hepatic remodeling have not been characterized. In this study, tadpoles were staged using the tables of Nieuwkoop and Faber (NF). Liver cells from pre- (NF56) or post- (NF66) metamorphic stage were cultured in the presence of Epo. β2-globin mRNA expression peaked at day 7 after the start of culture. Larval β2-globin was highly expressed in NF56-derived cells, while adult β2-globinwas detected in those of NF66...

BACKGROUND: Renal ischemia-reperfusion (IR) contributes to the development of acute renal failure (ARF). Oxygen free radicals are considered to be the principal components involved in the pathophysiological tissue alterations observed during renal IR. OBJECTIVES: In this study, we compared the effects of melatonin (MEL) and erythropoietin (EPO), both known antioxidant and anti-inflammatory agents, on IR-induced renal injury in rats. MATERIALS AND METHODS: Wistar albino rats were unilaterally nephrectomized and then subjected to 45 minutes of renal pedicle occlusion followed by 24 hours of reperfusion...

The erythropoietin (Epo) gene is under tissue-specific inducible regulation. Because kidney is the primary EPO-producing tissue in adults, impaired EPO production in chronic kidney disorders results in serious renal anemia. The Epo gene contains a liver-specific enhancer in the 3' region, but the kidney-specific enhancer for gene expression in renal EPO-producing (REP) cells remains elusive. Here, we examined a Conserved-Upstream-element for Renal-Epo-regulation (CURE) region that spans 17.4 kb to 3.6 kb upstream of the Epo gene and harbors several phylogenetically conserved elements...

Hepatitis C virus (HCV) infection is highly prevalent among patients on haemodialysis and leads to a poorer prognosis compared to patients who do not have said infection. Treatment with interferon and ribavirin is poorly tolerated and there are limited data on the experience with new direct-acting antivirals (DAAs). The aim of this study is to retrospectively analyse the current prevalence of HCV infection and efficacy and safety results with different DAA regimens in the haemodialysis population of 2hospital areas...

The majority of myelodysplastic syndrome (MDS) patients belong to the International Prognostic Scoring System (IPSS) and IPSS-revised (IPSS-R) lower-risk categories. Their precise diagnostics and prognostic stratification is often a challenge, but may ensure the optimization of therapy. The availability of diverse treatment options has significantly improved the quality of life and survival of this group of patients. Anemia is the most relevant cytopenia in terms of frequency and symptoms in lower-risk MDS, and may be treated successfully with erythropoietic stimulating agents, provided a careful selection is performed on the basis of IPSS-R, endogenous erythropoietin levels, and transfusion independence...

BACKGROUND: Cancer patients treated with alkylating agents and radiotherapy are exposed to high level of reactive oxygen species (ROS) in tissues. ROS can involve superoxide free radicals, peroxynitrite, singlet oxygen, nitric oxide and hydrogen peroxide. It is well documented that increased exposure to oxygen through a high metabolic rate could lead to a shortened life span. Ionizing radiation, use of drugs and the development of cancer can lead to cancer-induced anemia. Recombinant human erythropoietin (Epo) supplementation is one of the methods for treating anemia...

BACKGROUND: Infants with neonatal encephalopathy (NE) of hypoxic-ischaemic origin are at risk of oxidative and ischaemia-reperfusion injury, which may induce abnormal inflammatory responses involving excessive cytokine production and release in serum and cerebrospinal fluid (CSF). Systemic inflammation is found in infants with NE, and we therefore were interested in cytokines associated with hypoxia, including vascular endothelial growth factor (VEGF) and erythropoietin (Epo). OBJECTIVE: To investigate the relationship between Epo, VEGF levels, brain injury and outcome in a group of term infants exposed to perinatal asphyxia (PA) compared to controls...

The anemia of chronic kidney disease (CKD) is a common comorbidity seen in kidney diseases. It is also associated with increased cardiovascular morbidity and mortality and diminished quality of life. Often, patients with CKD of different stages require erythropoiesis-stimulating agents (ESAs) to maintain their hemoglobin (Hb) within the target range. Darbepoetin alfa is a newer ESA with a longer half-life than recombinant human erythropoietin (EPO). The objective of this study is to assess the efficacy and safety profile of twice-monthly (Q2W) and once a month (1QM) darbepoetin alfa in CKD patients, not on dialysis...

PURPOSE OF REVIEW: Patient blood management aims to improve patient outcome and safety by reducing the number of unnecessary red blood cell transfusions and vitalizing patient-specific anemia reserves. While this is increasingly recognized as best clinical practice in elective surgery, the implementation in the setting of trauma is restrained because of typically nonelective (emergency) surgery and, in specific circumstances, allogeneic blood transfusions as life-saving therapy. RECENT FINDINGS: Viscoelastic diagnostics allow a precise identification of trauma-induced coagulopathy...
