“Introduction Recently, several large cohort studies investigating renal anemia therapy have highlighted the biologically
plausible, but erroneous assumption that the normalization of hemoglobin (Hb) iron should attenuate cardiovascular disease risks and lead to a decline in the mortality rate of patients with chronic kidney disease (CKD), both before and after the initiation of maintenance hemodialysis (MHD) treatment [1–4]. Erythropoiesis stimulating agent https://www.selleckchem.com/products/azd9291.html (ESA) treatment decisions and guidelines based on the questionable assumption that Hb should be normalized or nearly normalized in the majority of CKD patients need to be reconsidered [5]. The development of safe and effective strategies aimed at obtaining better patient survival remains a challenge. In recent years, high-dose intravenous (IV) iron supplementation Ureohydrolase has become the standard of care; however, there are concerns as to whether this is the right approach. Recent studies on the mechanisms involved in iron metabolism have revealed that hepcidin is a master regulator of systemic iron availability [6, 7]. To maintain iron homeostasis, hepcidin tightly controls duodenal
iron absorption and iron recycling from senescent erythrocytes by tissue macrophages. Hepcidin is the principal hormone responsible for the physiological regulation of iron balance as well as its control in a variety of pathologic AR-13324 solubility dmso conditions, including the anemia of chronic disease (ACD). In this review, we address the mechanisms whereby pharmacological iron supplementation, especially via the IV route, may reduce the body’s capacity to absorb iron from the gut and to reutilize iron from endogenous sources [8], with particular focus on the importance of hepcidin in this process. ESA hyporesponsiveness Although normal or near-normal Hb levels in CKD patients were associated with reduced mortality in many observational studies [9–11], recent evidence from randomized clinical trials does not support a beneficial effect of Hb normalization on survival.
