Trends in the treatment of chronic kidney disease-associated anaemia in a cohort of haemodialysis patients: the Irish experience

AbstractBackgroundAnaemia among haemodialysis patients is treated with iron and erythropoietin-stimulating agents (ESAs). ESAs reduce requirements for blood transfusions but are also expensive and overzealous use may be associated with adverse outcomes. Recent international trends have been characterised by reduced ESA doses and a greater reliance on intravenous (IV) iron. We determined trends in prescribing patterns of ESAs and IV iron for the treatment of anaemia in two representative Irish dialysis centres and correlated with current guidelines and international trends.MethodsPatient data was accessed from the Kidney Disease Clinical Patient Management System (KDCPMS) for the period 2012 to 2014. We generated reports on ESA and iron doses, lab data (haemoglobin (Hb), transferrin saturation (TSAT) and ferritin) and patient population characteristics. We mapped the trends in ESA, iron dosing and lab parameters achieved. A linear mixed model determined the significance of these trends over time.ResultsESA dosing became lower in the second, third and fourth quarters of 2014. Dosing of iron increased throughout but a large increase was seen in the third and fourth quarters of 2014. Ferritin levels decreased and TSAT and haemoglobin levels increased. Changes in iron dosing were significant withp value of

AbstractBackgroundIron deficiency is a common cause of anemia in pediatric patients with hemodialysis-dependent chronic kidney disease (CKD-5HD). Ferric pyrophosphate citrate (FPC, Triferic ®) donates iron directly to transferrin, bypassing the reticuloendothelial system and avoiding iron sequestration. Administration of FPC via dialysate or intravenously (IV) may provide a suitable therapeutic option to current IV iron preparations for these patients.MethodsThe pharmacokinetics and safety of FPC administered via dialysate and IV to patients aged

AbstractBackground25-Hydroxyvitamin D (25OHD) deficiency is common in children with chronic kidney disease (CKD). It has been associated with an increased risk for anemia in both healthy US children and in adults with CKD. This association has not been explored in children with CKD.MethodsChildren aged 1 –16 enrolled in the Chronic Kidney Disease in Children (CKiD) study with mild to moderate kidney dysfunction, and with 25OHD measured at baseline (n = 580), were included in the analysis. The cross-sectional associations between 25OHD and hemoglobin (g/dL) and anemia were assessed. Anemia was defined as hemoglobin

ConclusionsOur findings support the presence of erythropoiesis inhibitory substances in uremic sera. EPO/EPO-R-dependent mechanisms may play a role in inhibiting erythropoiesis. The in vitro bioassay described herein may serve as an indicator of rHuEPO responsiveness which may encourage further investigation of underlying mechanisms of EPO resistance.

Z, Tesař V, Vokurka M Abstract Hepcidin is a key regulator of iron metabolism and plays an important role in many pathologies. It is increased by iron administration and by inflammation, while erythropoiesis downregulates its expression. It decreases iron availability and thus contributes to anemia of chronic diseases. The aim of the study was to measure hepcidin as a marker and pathogenic factor in ANCA-associated vasculitis (AAV). Hepcidin plasma concentration was measured by the immunological method in 59 patients with AAV and compared to patients with non-vasculitic etiology of chronic kidney disease, patien...

In this study, we further investigated the effects of other protein-bound uremic toxins on HIF-dependent EPO expression using EPO-producing HepG2 cells. We found that indoxyl glucuronide (IG) and IS, but not p-cresyl sulfate, phenyl sulfate, 3-indoleacetic acid or hippuric acid, inhibited hypoxia mimetic cobalt chloride-induced EPO mRNA expression. Furthermore, IG at concentrations similar to the blood levels in CKD patients inhibited the transcriptional activation of HIF induced by both cobalt chloride treatment and hypoxic culture. IG also induced CYP1A1 mRNA expression and nuclear translocation of AHR protein, indicatin...

Conclusions: TP0463518 induced dose-dependent EPO production, mainly derived from the liver in HV and CKD patients. These results suggest that TP0463518 is a new strategy for treating anemia in CKD, which can be used regardless of renal functions.Am J Nephrol 2018;48:157 –164

Authors: Auerbach M, Chertow GM, Rosner M Abstract INTRODUCTION: Ferumoxytol is a superparamagnetic molecule originally developed as a contrast agent for magnetic resonance imaging. Elemental iron is contained within the carbohydrate core and is released slowly after infusion allowing a large dose of iron to be administered in a short period of time. Ferumoxytol, originally approved for iron deficiency in chronic kidney disease, received a broad label for any cause of iron deficiency after oral iron intolerance or in those circumstances when oral iron is ineffective or harmful.
