β-hemoglobin disorders, such as β-thalassemia and sickle cell anemia are among the most prevalent inherited genetic disorders worldwide. These disorders are caused by mutations in the gene encoding hemoglobin-β (HBB), a vital protein found in red blood cells (RBCs) that carries oxygen from lungs to all parts of the human body. As a consequence, there has been an enduring interest in this field in formulating therapeutic strategies for the treatment of these diseases. Currently, there is no cure available for hemoglobin disorders, although, some patients have been treated with bone marrow transplantation, whose scope is limited because of the difficulty in finding a histocompatible donor and also due to transplant-associated clinical complications that can arise during the treatment...

Darbepoetin alfa (DA); hyper-glycosylated Erythropoietin alfa (EPO) is an essential treatment of anemia in patients with chronic kidney failure and cancer. In this study, DA and EPO were subjected to physicochemical stress factors that might be encountered during production, transport and storage (pH, temperature, agitation, repeated freeze-thaw and oxidation). An orthogonal stability-indicating assay protocol comprised of SE-HPLC, RP-HPLC, ELISA and SDS-PAGE was developed and validated to investigate the effect of further glycosylation of DA on the pattern and kinetics of degradation...

Chemotherapy with pemetrexed plus carboplatin followed by pemetrexed maintenance therapy is a first-line regimen for patients with advanced non-squamous non-small-cell lung cancer. This phase II clinical study investigated the efficacy and safety of this regimen in older patients (aged ≥65 years) with advanced non-squamous non-small-cell lung cancer. All patients received 4 courses of induction therapy with pemetrexed (500 mg/m(2)) combined with carboplatin once every 3 weeks. If patients had stable disease or achieved a complete or partial tumor response after 4 courses of pemetrexed + carboplatin therapy, maintenance treatment with pemetrexed monotherapy was administered until either disease progression or intolerable toxicity occurred...

Luteolin (Lut) belongs to the flavonoid family with various beneficial bioactivities. Here, we investigated whether Lut attenuate mercuric chloride (HgCl2)-induced renal injury in rat. We found that oral gavage administration of Lut (80mg/kg) alleviated anemia and renal histology upon HgCl2 treatment (80mg/L). Lut also significantly reduced HgCl2-induced oxidative stress and inflammatory, presenting as the reduced malondialdehyde (MDA) formation, increased glutathione (GSH) level, and inhibited activation of nuclear factor kappa B (NF-κB)...

Cancer treatment is one of the main challenges that face the scientific centers all over the world. The cancer incidence percentage increases year after year. The most used treatment for cancer is chemotherapy which is an application of systemic cytotoxic drug inside the patient. There are two main problems in chemotherapy that the cytotoxic drug is given systematically and cannot be localized in the tumor region in most cases that lead to killing the cancer cells as well as normal cells; and that cause the chemotherapy side effects like anemia, decrease in all blood cells count and platelets, nausea, vomiting, diarrhea, hair and nails loss and may cause a kind of blood toxicity...

A wide spectrum of clinical and clinicopathological findings in dogs with canine leishmaniosis (CanL) due to Leishmania infantum exists. However, the majority of clinical descriptions have been published a long time ago and recent studies in Europe are almost lacking. In addition, clinical classification of sick dogs is not well-standardized, with different classification systems used by clinical and epidemiological studies, making comparison of studies a difficult task. The aims of the study were to describe the clinicopathological findings of dogs naturally infected with L...

The carcinogenic potential of roxadustat (FG-4592), a novel orally active, heterocyclic small molecule inhibitor of hypoxia-inducible factor prolyl hydroxylase (HIF-PH) enzymes in clinical development for treatment of anemia, was evaluated in CD-1 mice and Sprague Dawley rats. Inhibition of HIF-PH by roxadustat leads to a rapid increase in cytoplasmic HIF-α concentrations, followed by translocation of HIF-α to the nucleus and upregulation of HIF-responsive genes, including erythropoietin. Roxadustat was dosed by oral gavage 3 times weekly (TIW) for up to 104 weeks in mice at 0, 15, 30, and 60 mg/kg and in rats at 0, 2...

Surgery and cisplatin-based treatment of hepatoblastoma (HB) currently guarantee the survival of 70-80% of patients. However, some important challenges remain in diagnosing high risk tumors and identifying relevant targetable pathways offering new therapeutic avenues. Previously, two molecular subclasses of hepatoblastoma tumors have been described, namely C1 and C2; C2 being the subgroup with the poorest prognosis, a more advanced tumor stage and the worst overall survival rate. An associated 16-gene signature to discriminate the two tumoral subgroups was proposed but it has not been transferred into clinical routine...

BACKGROUND: Iron deficiency anemia is a common finding in women of child-bearing age. Pica, or the ingestion of non-food or non-nutritive items, is a well-known manifestation of iron deficiency. A high sodium diet increases risk for nephrolithiasis. We describe the case of a 31-year-old woman with recurrent calcium nephrolithiasis and anemia who ate ice chips as well as spoons of salt daily. Treatment of pica may prove effective in preventing recurrent nephrolithiasis. CASE PRESENTATION: A 31-year-old white woman with a past medical history of menorrhagia, anemia, and recurrent calcium nephrolithiasis presented for preoperative evaluation prior to ureterolithotomy...

Anemia of chronic disease (ACD) is the second most prevalent anemia and frequently occurs in patients with acute or chronic immune activation. In the current study, we evaluated the therapeutic efficacy of Angelica sinensis polysaccharide (ASP) against ACD in rats and the potential mechanisms involved. The results showed that ASP inhibited inflammatory hepcidin in both HepG2 cells and ACD rats by blocking the IL-6/STAT3 and BMP/SMAD pathways. In ACD rats, the administration of ASP increased ferroportin expression, mobilized iron from the liver and spleen, increased serum iron levels, caused an elevation of serum EPO, and effectively relieved the anemia...

The female preponderance of many autoimmune diseases suggests a possible hormonal etiology. Little research exists on systemic and organ-specific autoimmune diseases and risk of breast cancer by tumor estrogen receptor (ER)- and progesterone receptor (PR)- status. Here we evaluate associations between selected systemic and organ-specific autoimmune diseases and breast cancer risk overall and by tumor ER- and PR-status. We used linked Surveillance, Epidemiology and End Results (SEER)-Medicare data, with first female breast cancer cases ages ≥66 years identified by SEER registries (years 1992-2011) (N = 209,929)...

Anemia is quite frequently diagnosed in older individuals and is a key indicator of various reactive and clonal conditions. Many underlying diseases, like the myelodysplastic syndromes (MDS), develop preferentially in elderly individuals. The prevalence of anemia at older age is increasing, and this is mainly due to more frequently applied diagnostics and demographic changes in our societies. The etiology of anemia at older age is complex and ranges from bone marrow failure syndromes to chronic kidney disease, and from nutritional deficiencies to inflammatory processes including inflammaging in immunosenescence...

Glucose-6-phosphate dehydrogenase (G6PD) deficiency is an X-linked erythrocyte enzyme disorder with relevance to malaria treatment policy. Treatment with the antimalarial primaquine can result in hemolytic anemia in G6PD-deficient patients. With increased interest in primaquine use, it is important to identify G6PD variants in Ethiopia to inform malaria treatment policy. In the present study, mutations in the G6PD gene are identified in a sample of patients with malaria in Jimma town in southwest Ethiopia. Plasmodium species of infection were confirmed using polymerase chain reaction (PCR) and gel electrophoresis...
