The effect of granulocyte transfusions on the course of infection in patients under treatment for acute leukemia was evaluated by comparing 19 febrile episodes in 15 patients receiving antibiotics alone with 18 febrile episodes in 13 patients receiving antibiotics in combination with granulocyte transfusions from ABO-matched donors. Both groups had a similar age, sex distribution and duration of disease prior to the febrile episode. About two-thirds of the patients in both groups had acute myeloblastic leukemia. 94% of the patients in the transfused group and 74% of the control group survived the febrile episode. In patients with positive blood cultures all transfused patients survived as compared to only 57% in the control group (p=0.05). In patients with persistent bone marrow failure 92% of the transfused patients survived as compared to 73% in the control group. Granulocyte transfusions had no effect on the outcome of febrile episodes in patients with negative blood cultures or early recovery of marrow function. These data appear to support the contention that granulocyte transfusions are beneficial in patients with blood culture-proved sepsis with persistent neutropenia.

Romiplostim Reduces Platelet Transfusion Needs in Multiple Myeloma Patients Undergoing Autologous Stem Cell Transplantation.

Department of Clinical Hematology and Bone Marrow Transplant (BMT), Command Hospital, Lucknow, IND.
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.

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).
