We compared the capacity of superlow-dose of antibodies to erythropoietin (Poetam) and recombinant erythropoietin (Recormon) to stimulate the recovery of adriamycin-suppressed erythropoiesis in mice. Both preparations exhibited high erythron activation capacity and considerably increased the content of erythrocytes and reticulocytes in the peripheral blood and content of erythrokaryocytes and erythroid precursors in the hemopoietic tissue of experimental animals. The effect of Recormon manifested immediately after injection, while the effect of Poetam was somewhat delayed, but more lasting (due to activation of host erythropoietin system).

Unlabelled: Malaria, caused by spp., is a global health concern linked to anemia and increased mortality. Compensatory erythropoiesis seen during acute anemia results in an increased circulating reticulocyte count ( , immature RBC) a key factor in understanding the relationship between pre-existing anemia and burden.

Purpose: To investigate how obesity affects the pharmacokinetics of biologics in a rat model.
Method: Male Long-Evans rats were fed a high-fat diet from the age of 3 weeks and development of obesity was monitored by measuring body size and composition (fat and lean mass). The animals received nivolumab (1 and 8 mg/kg) or recombinant human erythropoietin (rHuEPO, 1000 IU/kg) by intravenous or subcutaneous injection.

We report the case of a 5-year-old girl with a rare P-null phenotype who presented for a neurosurgical procedure at our center. The case is unique as this patient was one of the two P-null phenotype cases reported in India and we report how we could successfully arrange a rare blood unit for her. As it was challenging to find a donor for her, autologous blood was collected.

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.

Clinical Features: Sickle cell patients may develop a multitude of antibodies and experience life-threatening events with transfusion such as hyperhemolysis syndrome or delayed hemolytic transfusion reaction. Further transfusion may not be possible in such cases.
Therapeutic Challenge: When conventional blood products are not available for transfusion yet the patient requires additional oxygen-carrying support, artificial oxygen carriers may be required.
