Prevalence data concerning viral hepatitis and human immunodeficiency virus (HIV) in the general population are usually scarce. We aimed for a large cohort representative of the general population that required little funding. Autologous blood donors are relatively representative of the general population, and are tested for viral hepatitis and HIV in many countries. However, frequently these data are not captured for epidemiologic purposes. We analysed data from well over 35,000 autologous blood donors as recorded in 21 different transfusion centres for anti-hepatitis C virus (HCV), HBsAg and anti-HIV, as well as TPHA if available. We found a lower prevalence of hepatitis B virus and HCV in East vs West Germany, 0.2%vs 0.32% and 0.16%vs 0.32% respectively, which confirms earlier data in smaller cohorts, thus supporting the value of our approach. HIV was too rare to disclose significant differences, 0.01%vs 0.02%. TPHA was higher in East (0.34%) vs West Germany (0.29%) without significant differences. HCV was more frequent in women vs men. Transfusion institutes managing autologous blood donations should be used as a resource for epidemiological data relating to viral hepatitis and HIV, if such testing is performed routinely. This approach generates data relating to the general population with special emphasis on undiagnosed cases.
Nevertheless, attention has to be paid to these exceptionally rare symptoms, as in some publications, thromboembolic or even bleeding complications were reported.
Background: A new pneumatic tube system to transport red blood cell concentrates (RBCC) and fresh frozen plasma (FFP) was to be evaluated, followed by integration into the quality management system. Material and Methods: First, with the pneumatic tube system we transported 12 RBCC on day 35 after production. We estimated hemoglobin, hemolysis rate, ATP, potassium, LDH and lactate of the RBCC before and after transportation. In a second experiment, we transported 12 RBCC on day 10 after production. We tested these 12 RBCC for hemolysis rate, potassium and ATP, and compared them to 12 RBCC of the control group on days 10, 20, 30, and 35 after production. At the end of storage, all were tested for bacterial contamination. 36 FFP units were transported in frozen state over the same distance. Upon thawing, the samples were tested for factor VIII, antithrombin activity, and sterility. Results: The pneumatic tube transport of RBCC at the end of their usability and on day 10 after production including storage did not lead to any significant differences with regard to the tested parameters before and after transport. Factor VIII and antithrombin activities in all FFP units were between 70–100%. All 36 FFP were sterile and not damaged by the transportation. Conclusion: Transport of RBCC and FFP in a pneumatic tube did not have any negative effect on the quality and storage stability of the products. By using this pneumatic tube system, blood products can be transported safely, fast and efficiently within a clinical center.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
