title: Transfusion-transmissible infections among U.S. military recipients of emergently transfused blood products, June 2006-December 2012.
abstract: In austere deployment environments, transfusion of freshly collected blood products from volunteer donors is sometimes necessary to save wounded service members' lives. Because these blood products may have an increased risk of transmitting bloodborne pathogens, recipients are administratively tracked and offered serial serologic testing by the Blood Look Back (BLB) program. This study evaluates the frequency of transfusion-transmissible infections (TTIs) in U.S. service member (SM) recipients of non-FDA-compliant blood products from 1 June 2006 through 31 December 2012. Routine BLB program efforts identified and evaluated 1,127 SM recipients for evidence of seven TTIs for 12 months following transfusion. The Defense Medical Surveillance System was then queried for evidence of provider-diagnosed TTIs and the results were compared. A single, previously reported incident case of human T-lymphotropic virus (rate of 1.3 per 1,000 persons) was the only TTI identified during the study period. Screening of recipients identified two (rate of 1.9 per 1,000 persons) prevalent (pre-transfusion) cases of chronic hepatitis B virus (HBV) infection, 16 (rate of 15.5 per 1,000 persons) prevalent cases of naturally acquired immunity to HBV and seven (rate of 6.8 per 1,000 persons) prevalent cases of hepatitis C virus infection. No cases of infection with human immunodeficiency virus, syphilis, Trypanosoma cruzi, or West Nile virus were identified.
