(Intensive) chemotherapy can result in a reduced production of white blood cells (immune cells), especially neutrophils. These neutrophils are essential in the defence against bacteria and fungi. Patients with longstanding neutropenia run the risk of developing a life-threatening infection. Administration of neutrophils from healthy donors is an effective way to fight such infections in case antibiotic and/or antifungal therapy fails. However, patients themselves need to recruit these donors, which are subjected to extensive medical screening and dexamethasone/growth hormone (GCSF) therapy. This is a time consuming, cumbering procedure for the patient, family, doctor and donor, with unknown long term effects of the GCSF. Therefore, we are trying to develop a new granulocyte transfusion product, from residual pooled buffy coats, which we will compare to the standard G-CSF/dexamethasone product. Also, we will perform a biomarkerstudy in adult hematology patients in order to refine the timing, indications and eligible patients for granulocyte transfusions.
