During the course of a prospective study of lead exposure and pregnancy outcome in 1,502 women, we tested the hypothesis that environmental lead exposure is associated with depressed serum erythropoietin concentration. At mid-pregnancy and at delivery, blood samples were stratified by hemoglobin concentration; within each hemoglobin stratum, sera of women with the lowest and highest whole blood lead concentrations were selected for serum erythropoietin analysis. Analysis of variance revealed that women with higher blood lead levels had inappropriately low serum erythropoietin at both mid-pregnancy and at delivery. Thus, depressed serum erythropoietin appears to indicate lead nephrotoxicity, and it may also be responsible for the anemia associated with lead poisoning.

Patients with chronic inflammation are burdened with anemia of inflammation (AI), where inflammatory cytokines inhibit erythropoiesis, impede erythropoietin production, and limit iron availability by inducing the iron regulator hepcidin. High hepcidin hinders iron absorption and recycling, thereby worsening the impaired erythropoiesis by restricting iron availability. AI management is important as anemia impacts quality of life and potentially affects morbidity and mortality.

This study aimed to find whether oral administration of calf bone marrow hydrolysate liposomes (CBMHL) can improve renal anemia. Calf bone marrow was defatted, papain hydrolyzed, liposomalized and lyophilized. Its hematopoietic ability was proved by the colony formation experiment of umbilical cord blood hematopoietic stem cells in vitro.

The incidence of anemia increases with the stage of chronic kidney disease (CKD). Erythropoietin (EPO) deficiency is a common cause of anemia in CKD. Erythropoietin-stimulating agents (ESAs) are the mainstay of the treatment.

Anemia and mineral and bone disorder (MBD) are significant complications of chronic kidney disease (CKD). The erythropoietin (Epo) pathway plays a key role in both of these processes in CKD. Another molecule that plays an important role in CKD-MBD is fibroblast growth factor (FGF)-23, whose main role is to maintain serum phosphate levels in the normal range, acting via its co-receptor Klotho; however, its activity may also be related to anemia and inflammation.

Background: Nucleated red blood cells (nRBCs) are increased by disease processes and hematopoietic stress.
Objectives: To evaluate the utility of nRBCs as a marker of disease severity and prognosis in dogs with systemic inflammatory response syndrome (SIRS).
Animals: Sixty-two client-owned dogs met the criteria of SIRS without anemia.
