The study aimed at the evaluation of metabolic effect of recombinant human erythropoietin (EPO) in children treated with repeated hemodialyses. The research included 16 patients aged 7-17 years of life. The observations were carried out for 6 months prior to and during EPO administration programme. In that time there were monitored changes in peripheral blood count, lean body mass, protein catabolic rate- pcr, urea time averaged concentration TAC and dialysis index KT/V. The results obtained in both phases of the investigation revealed that correction of anemia by means of EPO evokes in children a significant increase of lean body mass, while TAC decreases. The two factors combined speak for anabolic effect of EPO in these patients. The results of peripheral blood count obtained in the groups with high and acceptable exposure to uremic toxemia did not differ significantly, this proves that uremic toxemia does not exert inhibitory effect on erythropoiesis stimulated by EPO administration.

Induction of Erythropoietin by dietary Medium-Chain Triacylglycerol in Humans.

Erythropoietin (EPO) is pivotal in regulating red blood cell (erythrocyte) concentrations and is primarily synthesized in the kidney. Recent research has unveiled a possible link between elevated circulating concentrations of ketone bodies (KB) and circulating EPO concentrations, however, it is not known whether nutritionally induced endogenous ketogenesis can be a stimulus to induce EPO in humans. Therefore, this study aimed to assess whether acute and chronic intake of medium-chain fatty acid (MCFA)-containing triacylglycerol (MCT), which rapidly enhances endogenous circulating KB, would elevate circulating EPO concentrations in humans, as indicated by prior work with exogenous KB administration.

Obesity and iron deficiency (ID) are widespread health issues, with subclinical inflammation in obesity potentially contributing to ID through unclear mechanisms. The aim of the present work was to elucidate how obesity-associated inflammation disturb iron metabolism and to investigate the effect of intravenous (IV) iron supplementation on absolute iron deficient pre-obese (BMI 25.0-29.

Post translational modifications (PTMs) of proteins play an integral role in maintaining the overall structure and function of proteins including their proper folding, binding, and potency. However, not all PTMs play a positive role in protein drugs as some can lead to product-related impurities that negatively impact protein function. One example of a PTM is trisulfide formation, which appears as a product related species in multiple biologic drug products.

Chronic kidney disease (CKD) patients often suffer from complications such as anemia as the kidney function declines. More than 25% of CKD hemodialysis patients in China are complicated with renal anemia due to renal and hepatic impairment in the production of erythropoietin (EPO). In recent years, prolyl hydroxylase domain (PHD) inhibitors have been approved in China and Japan for the treatment of CKD patients complicated with anemia.

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.
