简要总结
This is a prospective, randomized, double-blind, controlled study to determine the effectiveness of Mirasol-treated fresh whole blood (FWB) versus Standard-issue FWB for preventing transmission of transfusion-transmitted infections (TTIs). The incidence of pre-defined viral, bacterial, or parasitic TTIs in previously negative participants will be assessed by changes in laboratory findings at multiple time points over the course of the clinical trial.
详细描述
Anemic patients from Mulago Hospital Complex who require fresh whole blood transfusion and with any of the following conditions will be considered for recruitment: cancer, general medical or surgical, obstetric hemorrhage, and/or sickle cell. Eligible patients will be randomized 1:1 to receive transfusions of Mirasol-treated FWB (n = 1,000) or standard issue FWB (n = 1,000) during the 10 week follow-up interval. The Ugandan Blood Transfusion Service collects and screens donor blood and will provide both Standard and Mirasol-treated blood for transfusion. Currently, all standard FWB is non-leukoreduced and tested by serology for human immunodeficiency virus (HIV), hepatitis B virus (HBV), and hepatitis C virus (HCV) and by rapid plasma regain (RPR) for syphilis in Uganda; any units that test positive are discarded. The intervention will treat standard FWB that has been screened for HIV, HBV, HCV, and syphilis with Mirasol PRT.
The start of study treatment (Day 0) will be defined as the initiation of the first FWB transfusion. Recipient blood collected at pre-transfusion, Day 2, Day 7, Week 4, and Week 10 will be compared with donor blood to evaluate for incidence of pre-defined TTIs: bacteria, HBV, HCV, hepatitis E virus (HEV), human herpesvirus-8 (HHV8), HIV, and malaria. Recipients will be evaluated for possible transfusion reactions at those timepoints, as well as 2 to 6 hours after the first transfusion.
The primary objective of the Uganda Mirasol Trial is to evaluate the efficacy of Mirasol-treated FWB to prevent transfusion transmission of emerging infectious diseases. The secondary objectives are to evaluate the impact of TTIs in Uganda and potential for Mirasol PRT, as well as to assess the feasibility and sustainability of implementing whole blood Mirasol pathogen reduction technology (PRT) in austere settings.
