Granulocyte transfusions may be useful for neutropenic pediatric patients with refractory bacterial or fungal infections. Many potential adverse sequelae associated with granulocyte transfusions are well recognized, including febrile reactions, fluid overload, alloimmunization, and lung injury. Other potential adverse sequelae, however, are less well known. This case report describes an infant with familial hemophagocytic lymphohistiocytosis who developed polycythemia (hemoglobin 10-17.6 g/dl) following four daily transfusions of 20 ml/kg of apheresis collected, steroid stimulated donor granulocytes. Expanded knowledge of potential risks of transfused granulocytes will allow for rapid recognition of transfusion-related complications, should they occur.

Background: There is no standard treatment to accelerate recovery from melphalan-induced thrombocytopenia in multiple myeloma (MM) patients undergoing autologous stem cell transplantation (ASCT). Romiplostim, a thrombopoietin receptor agonist, has been developed to upregulate platelet production.

Objective: This study aimed to assess the efficacy and safety of romiplostim in reducing platelet transfusions post-ASCT in MM patients.

Bidirectional role of neutrophils in tumor development.

Neutrophils, traditionally considered as non-specific components of the innate immune system, have garnered considerable research interest due to their dual roles in both promoting and inhibiting tumor progression. This paper seeks to clarify the specific mechanisms by which neutrophils play a bidirectional role in tumor immunity and the factors that influence these roles. By conducting a comprehensive analysis and synthesis of a vast array of relevant literature, it has become evident that neutrophils can influence tumor development and invasive migration through various mechanisms, thereby exerting their anti-tumor effects.

There is a high medical need to develop new strategies for the treatment of patients with acute myeloid leukemia (AML) refractory to conventional therapy. In vitro, the combinations of the blast-modulatory response modifiers GM-CSF + Prostaglandin E1, (summarized as Kit M) have been shown to convert myeloid leukemic blasts into antigen-presenting dendritic cells of leukemic origin (DC) that were able to (re-)activate the innate and adaptive immune system, direct it specifically against leukemic blasts, and induce memory cells. This study aimed to investigate the immune modulatory capacity and antileukemic efficacy of Kit M in vivo.

Background And Objectives: Granulocyte transfusion supports patients with severe neutropenia. Maintaining a pool of eligible donors and optimizing donation frequency are essential for ensuring an adequate supply while safeguarding donor well-being. This study investigates the impact of donation frequency on erythrogram parameters, focusing on sex-specific differences.

Background: Relapsed acute myeloid leukemia (AML) and high-risk myelodysplastic syndrome (HR-MDS) are associated with a poor prognosis. It is unknown which re-induction therapy provides the highest chance of durable remission. Commonly used therapies are high dose cytarabine (HiDAC) and triple therapy consisting of fludarabine, cytarabine, and idarubicin combined with granulocyte colony-stimulating factor (FLAG-IDA).
