The independent association between the indices of iron stores or administered intravenous iron, both of which vary over time, and survival in patients who are on maintenance hemodialysis (MHD) is not clear. It was hypothesized that the observed associations between moderately high levels of three iron markers (serum ferritin, iron, and iron saturation(More)
BACKGROUND Parenteral iron is often required by hemodialysis patients to maintain adequate iron stores. Until recently, the only available form of intravenous iron was iron dextran, which is associated with significant adverse reactions, including anaphylaxis and death. Sodium ferric gluconate complex (SFGC) was recently approved for use in the U.S. under(More)
BACKGROUND Iron dextran administration is associated with a high incidence of adverse reactions including anaphylaxis and death. Although dextran, rather than iron, is believed to be the cause of these reactions, it is not known whether iron dextran-sensitive patients can be safely administered another form of parenteral iron, sodium ferric gluconate in(More)
Estimates suggest that one third of United States health care spending results from overuse or misuse of tests, procedures, and therapies. The American Board of Internal Medicine Foundation, in partnership with Consumer Reports, initiated the "Choosing Wisely" campaign to identify areas in patient care and resource use most open to improvement. Nine(More)
BACKGROUND Almost all hemodialysis (HD) patients require intravenous iron therapy to correct their anemia and maintain their iron stores. Sodium ferric gluconate complex (SFGC) is approved by the Food and Drug Administration (FDA) for treatment of iron deficiency anemia in HD patients at individual doses up to 125 mg over 10 minutes (12.5 mg/min) and has(More)
Leptin, the gene product of the ob gene, is important in the control of appetite in rodents and may have an important role in humans. The clearance of leptin from the circulation is unknown. As the leptin receptor is present in the kidney, we evaluated the role of the kidney in removing circulating leptin in humans. We measured leptin in aortic and renal(More)
Two previous short-term studies (12 weeks and up to 16 weeks) that used androgens to supplement recombinant human erythropoietin (rHuEPO) for the treatment of the anemia associated with end-stage renal disease showed divergent results. Both studies were limited by their brief duration, since the hematopoietic effect of androgens does not peak until 5(More)
BACKGROUND A previous single dose placebo-controlled double-blinded trial showed an extremely low (0.4%) intolerance rate of sodium ferric gluconate complex (SFGC) in SFGC-naive haemodialysis patients. No large prospective trials have assessed the safety of SFGC during repeated exposure in the outpatient haemodialysis setting. METHODS Chronic(More)
OBJECTIVE The prevalence of hepatitis C virus (HCV) in patients on chronic hemodialysis (HD) is near 9%. Transaminases, which are lower in HD patients, are not effective in screening for HCV. Our aim was to design an HCV risk stratification strategy incorporating lowered aminotransferase levels and other clinical parameters. METHODS Patient serum from 168(More)
Cyclosporine A is the mainstay of modern immunosuppressant therapy in human organ transplants. However, its use has been associated with nephrotoxicity and hypertension that may be hemodynamically mediated. This study was undertaken to see if the calcium channel blocker, isradipine, could improve renal hemodynamics by decreasing renal vascular resistance(More)
