Efficacy estimation of erythropoiesis-stimulating agents using erythropoietin-deficient anemic mice

Efficacy estimation of erythropoiesis-stimulating agents using erythropoietin-deficient anemic mice.

Arterial hypertension induced by erythropoietin and erythropoiesis-stimulating agents (ESA).

This review summarizes the evidence for a hypertensinogenic effect of Erythropoietin (Epo) in normal human subjects and predialysis, hemodialysis, and continuous ambulatory peritoneal dialysis (CAPD) patients. The possible mechanisms of Epo-induced hypertension are examined with in vivo animal and in vitro data, as well as pathophysiological human studies in both normal subjects and CKD patient...

Erythropoietin and erythropoiesis in anemic man following androgens.

T hat androgenic hormones stimulate erythropoiesis in animals and man has been known for many years.1’2 The principle mechanism for this activity probably results from an increased production of erythropoietin since both serum and urine levels are elevated by androgens.35 Even when plasma erythropoietin content is high, as in most anemias, further enhancement may occur after administration of t...

Pharmacokinetics of erythropoietin in genetically anemic mice.

We examined the pharmacokinetics of recombinant human erythropoietin (rh-EPO) in genetically anemic mice (W/Wv genotype) to clarify its disposition mechanism in hematopoietic injury such as occurs in aplastic anemia. After rh-EPO was administered to W/Wv and control (+/+ genotype) mice once a day for 1 week at different doses, both the hematocrit (Hct) and tissue uptake clearance (CLup) of 125I...

The role of erythropoietin stimulating agents in anemic patients with heart failure: solved and unresolved questions

Anemia is a common finding in congestive heart failure (CHF) and is associated with an increased mortality and morbidity. Several conditions can cause depression of erythroid progenitor cells: reduction of iron absorption and reuptake, decreased bone marrow activity, reduced endogenous erythropoietin production, and chronic inflammatory state. Anemia's etiology in CHF is complex and partially u...
