The number of patients requiring hemodialysis is continuously increasing around the world. Hemodialysis affects patient quality of life and it is also associated with a higher risk for cardiovascular events. In addition to traditional risk factors for cardiovascular events such as hypertension, hyperlipidemia, and diabetes, hemodialysis is associated with hyperphosphatemia, chronic inflammation, vascular calcification, and anemia which accelerate atherosclerosis, vascular stiffness, and cardiac ischemia. Treatment strategy for coronary revascularization in this progressive disease remains controversial...

OBJECTIVE: Ferumoxytol has demonstrated superior efficacy compared with oral iron in treating iron deficiency anemia in chronic kidney disease (CKD) patients. However, an economic evaluation of ferumoxytol has not been conducted. The aim of this study was to analyze the cost-effectiveness of treating iron deficiency anemia in adult non-dialysis-dependent CKD patients with ferumoxytol as compared with oral iron, alone or in combination with erythropoietin-stimulating agents (ESAs). METHODS: A decision analytic model compared health outcomes and costs associated with 5-week outpatient treatment of adult non-dialysis-dependent CKD patients with ferumoxytol or oral iron, each as monotherapy or in combination with ESAs in the USA...

Anemia has been widely studied in global health contexts because of severe nutritional deficiency, and more recently, inflammatory status, but chemical exposures are rarely considered. Until recently, "anemia" was used synonymously with "iron deficiency anemia (IDA)" in global health settings. However, only 50% of anemia cases worldwide are IDA. Environmental toxicology studies of anemia risk have generally focused on populations in developed countries, albeit with high exposure to environmental toxicants, such as lead or cadmium...

Life expectancy and quality of life for those born with congenital heart disease (CHD) have greatly improved over the past 3 decades. While representing a great advance for these patients, who have been able to move from childhood to successful adult lives in increasing numbers, this development has resulted in an epidemiological shift and a generation of patients who are at risk of developing chronic multisystem disease in adulthood. Noncardiac complications significantly contribute to the morbidity and mortality of adults with CHD...

Background: Hepcidin secreted by hepatocytes is a key regulator of iron metabolism throughout the body. Hepcidin concentrations are increased in chronic kidney disease (CKD), contributing to abnormalities in iron metabolism. Levels of indoxyl sulfate (IS), a uremic toxin, are also elevated in CKD. However, the effect of IS accumulation on iron metabolism remains unclear. Methods: We used HepG2 cells to determine the mechanism by which IS regulates hepcidin concentrations...

REVIEW
Donald A Mahler
Dyspnea is due to an imbalance between the demand to breathe and the ability to breathe. The prevalence is ∼30% for those 65 years or older with walking on a level surface or up an incline. Dyspnea is a strong predictor of mortality in elderly individuals. Anemia, cardiovascular disease, deconditioning, psychological disorders, and respiratory diseases are common causes of dyspnea. Initial treatments to relieve breathing discomfort should be directed toward improving the pathophysiology of the underlying disease...

BACKGROUND: Drug-induced immune hemolytic anemia (DIIHA) is rare, but potentially life-threatening. A high index of clinical suspicion is required for diagnosis, since the number of medications known to induce DIIHA continues to expand. Additionally, in vitro antibody reactivity against reagent additives has been reported, which may complicate test interpretation. CASE REPORT: A 61-year-old group A, D+ woman with a history of negative antibody detection tests developed hemolytic anemia on Postoperative Day 7 after repeat incision and drainage of a chronically infected right knee prosthesis...

Egypt has the highest hepatitis C virus (HCV) prevalence in the world. Sofosbuvir is a new highly effective drug for treatment of HCV infection. Compared to previous treatments, sofosbuvir-based regimens provide a higher cure rate, fewer side effects, and a two- to fourfold reduced duration of therapy. The aim of this study was to evaluate the antiviral efficacy, safety, and tolerability of sofosbuvir plus ribavirin in Egyptian patients with liver cirrhosis due to chronic HCV infection. We studied 2400 cirrhotic Egyptian patients with chronic HCV infection who were treated with dual therapy with sofosbuvir and ribavirin for 24 weeks...

Sickle cell disease (SCD) is a chronic blood disorder that is often associated with acute and chronic cerebrovascular complications, including strokes and impaired cognition. Using functional resting state magnetic resonance images, we performed whole-brain analysis of the amplitude of low frequency fluctuations (ALFF), to detect areas of spontaneous blood oxygenation level dependent signal across brain regions. We compared the ALFF of 20 SCD patients to that observed in 19 healthy, age and ethnicity-matched, control subjects...

Iron is essential for various cellular processes, but an excess of iron may cause organ damage through the production of reactive oxygen species. Therefore, the amount of iron in the body must be strictly controlled. The central regulator of systemic iron homeostasis is hepcidin, which is primarily produced in the liver. Various molecules, including HFE, transferrin receptor 2 (TFR2), and hemojuvelin (HJV), are involved in sensing systemic iron status. Hepatocytes produce hepcidin in response to excess iron and inflammatory stimuli (e...

Chronic kidney disease leads to dysfunction of renal erythropoietin-producing cells, resulting in a decrease in erythrocyte production. A decrease in oxygen delivery to vital organs due to anemia results in worse quality of life and is associated with poor prognosis of the patients. Treatment with human recombinant erythropoietin or its improved version of erythropoiesis-stimulating agent (ESA) with a longer half-life is effective. However, some patients show hyporesponsiveness to ESA. Hyporesponsiveness to ESA, which can be induced by factors such as inflammation and uremic toxins, is associated with poor prognosis...

Esophageal hiatal hernia is defined as the prolapse of one or more intra-abdominal organs through the esophageal hiatus. Four types are identified: type Ι or sliding hiatal hernia, type II or paraesophageal hernia (PEH), type III or mixed hernia and type IV. Congenital type II esophageal hiatal hernia is caused by a remaining gap after the formation of pleuroperitoneal membrane. We present a case of a six years old boy admitted to our department, appearing with asymptomatic anemia, who was incidentally diagnosed with Type II esophageal hiatal hernia...
