Perfil epidemiológico dos doadores de sangue da Fundação Hemopa em Belém-Pará, infectados pelo Vírus da imunodeficiência humana

Abstract

The profile´study of positive sorology blood donors for HIV is essential to review the methods that have been used in clinical screening for the strict observance of the rules set for the exclusion of candidates for donation is possible. The assessment of profiles was performed by a study in which, blood donors confirmed positive for HIV-1 (n=96) were compared with a control group of false-positive donors in screening test for HIV ( n=224). This research, conducted with the focus on transfusion safety and to reduce the residual risk of virus transmission by transfusion, was made in the period from 01 January 2006 to 31 March 2008. The demographics and potential risk factors for HIV infection were evaluated in interviews post-donation. The omission of risk factors in screening clinic - which should have generated refusing donors - has been reported in 74.69% of respondents. In multivariate analysis the risk factors for HIV infection were: donors men who had sex with other men, donors who had four or more sexual partners in the last 12 months, users of illicit drugs donors, donors who have made inconsistent use of condoms in sexual relations, all with statistical significance (p<0.0001) and greater chance of risk to 1.0 (OR> 1.0). We conclude that these factors listed above are important in the transmission of HIV by blood transfusion and that the MSM are still the major predictors of HIV infection in the population studied.
