          Abstract

          The Brazilian Ministry of Health has made tests for HIV1 and HIV2, HTLV I and HTLV II, HCV, HBV, T. cruzi, T. pallidum and Plasmodium in endemic areas, mandatory for all blood collection bags used in the country. However, blood-borne infectious diseases are not investigated in blood recipients before transfusion. For this study, a serological evaluation of recipients before transfusion was carried out. Prior to transfusion, serum samples from 159 blood recipients were analyzed using the same tests used in the serological screening of blood donors. The blood recipients were divided into three groups: Group 1 (G1), patients who had never received blood, Group 2 (G2), patients who had received multiple transfusions and Group 3 (G3) one-off recipients. SPSS v.8 was used for statistical analysis. Values of p<0.05 were taken to be significant. The results showed that 62 blood recipients tested positively for one or more blood-borne infectious diseases. In addition, several recipients were unaware of their serological status before the transfusion. The identification of blood-borne infectious diseases in recipients before transfusion could avoid the State being held responsible by recipients who were unaware that they were carriers of such diseases and only found out about their contamination after transfusion.

          O Ministério da Saúde brasileiro determina a realização de testes sorológicos para HIV 1 e 2, HTLV I e II, HCV, HBV, T. cruzi, T. pallidum e Plasmodium nas áreas endêmicas, em todas as bolsas de coleta de sangue utilizadas no País. Entretanto, as doenças infecciosas transmissíveis através do sangue não são inves­tigadas nos receptores de sangue (RS) antes da transfusão. Neste estudo, realizamos uma avaliação sorológica dos RS anterior à transfusão. Amostras de soro de 159 RS foram analisadas aplicando-se os mesmos testes utilizados na triagem soro­lógica dos doadores de sangue. Os RS foram divididos em três grupos: Grupo 1 (G1), pacientes que nunca receberam sangue, Grupo 2 (G2), pacientes politransfundidos e Grupo 3 (G3) receptores eventuais. Para a análise estatística utilizou-se o pro­grama SPSS v.8. Valores de p<0,05 foram considerados signi­ficantes. Os resultados mostraram que 62 RS apresentaram positividade para uma ou mais doenças infecciosas trans­missíveis pelo sangue. Além disso, vários RS desconheciam seu estado sorológico anterior à transfusão. A identificação de doenças infecciosas transmissíveis pelo sangue em RS anterior à transfusão poderia evitar a responsabilidade do Estado pelos RS que desconheciam ser portadores de tais doenças e apenas tiveram conhecimento de sua contaminação após a transfusão.

          Worldwide overview of existing haemovigilance systems.

          Jean Faber (2004)
          Haemovigilance is a "quality process" with the aim to improve quality and increase safety of blood transfusion, taking into account that haemovigilance covers and surveys all activities of the blood transfusion chain from donors to recipients. Haemovigilance is indispensable when it comes to safety and quality of blood transfusions. Within the European Union (EU), the European Blood Directive requires haemovigilance in each Member State: the intention has been to rely on the existing or developing national systems. There are significant differences in haemovigilance around the world, in terms of definition, organisational schemes, state of development and implementation. These differences are more pronounced outside the EU: in some countries, even basic traceability causes a problem while in others systems similar as the most developed ones in the EU are implemented.
