Extracorporeal photopheresis: Is one ounce of blood enough? Case reports.

Extracorporeal photopheresis (ECP) has proven effective in the treatment of several diseases, including acute and chronic graft-versus-host disease (GVHD) after allogeneic hematopoietic stem cell transplantation. In its standard version, ECP requires leukapheresis to obtain a fraction of mononuclear cells. The possibility of using leukapheresis is limited by the requirements for vascular access and the somatic status of the patient.

Efficacy and safety of a reduced dose of plerixafor in combination with granulocyte colony-stimulating factor in healthy haploidentical stem cell donors.

Background And Objectives: Implementation of the technique of immunomagnetic selection requires the procurement of a large number of CD34+ cells from haploidentical donors within a single apheresis procedure. The release of stem cells with granulocyte colony-stimulating factor (G-CSF) alone is unsatisfactory in a number of donors, and plerixafor, a CXCR4 chemokine receptor antagonist, could be used as an additional mobilization agent. The aim of our study was to examine whether a lower dose of plerixafor (0.

Quality assessment of red blood cell suspensions derived from pathogen-reduced whole blood.

Background: We used laboratory indicators to evaluate the quality of pathogen-reduced red blood cell suspension (RBCS) compared with gamma-irradiated RBCS.

Materials And Methods: To determine biochemical and metabolic parameters of RBCS, we obtained 50 whole blood units from healthy volunteers and randomized them into 2 groups: 25 were pathogen-reduced, and then, RBCS prepared from them. RBCS from the other 25 was gamma-irradiated.

The pathogen-reduced red blood cell suspension: single centre study of clinical safety and efficacy in children with oncological and haematological diseases.

Background: Transmission of pathogens through blood transfusion is still of great concern to clinicians, patients and blood providers. Pathogen reduction technologies (PRT) have been successfully applied for the treatment of labile blood components, such as plasma, platelets and whole blood (WB), which are now used in routine in many countries. We report the clinical evaluation of suspension of red blood cells (RBC-S) derived from the WB treated with riboflavin and UV light (RF+UV).
