Perfil epidemiológico dos doadores de sangue infectados pelo vírus HTLV I/II, no Hemocentro de Fortaleza nos anos de 2012 e 2013

Abstract

HTLV (lymphotrophic virus human T cell) belongs to the Retroviridae family, genus Deltaretrovirus . HTLV type 1 is associated with the pathogenesis of / tropical spastic paraparesis and myelopathy leukemia / lymphoma Adult T cells (ATL / L) while HTLV -II has not been associated with any disease. Since 1993, it is required, in Brazilian blood banks, the survey to detect antibodies for HTLV I/II. The goal of this study was to analyze the frequency of positive cases of HTLV and characterize the epidemiological profile of blood donation, infected by HTLV virus, at a blood bank in Fortaleza in years of 2012 and 2013, according to age, genre, scholarity, marital status, breed and city where people live, in population of donors and characterize in relation to the kind of accomplished donation, local of collect and numbers of donations. The data were collected in HEMOCE database and statistically analyzed using Microsoft Excel 2010 program. The results showed that among the 111,931 donors, 15 samples were positive for effectively screening and confirmatory tests, showing a prevalence of 0.013 %. In positive cases was observed a medium age of 40.2 years, the predominant sex was female with (53.3%), the color was considered mulatto/brown (66.6%), most were married (53.3%) who had completed high school (66.7%), the type of donation was voluntary (93.3%), all donors were from Fortaleza, carried out the collection in HEMOCE and were first blood donors. Despite the low frequency of HTLV in the population, it is necessary to make actions that aim to inform the public about the existence of this virus, so unknown in our world and raise awareness about the importance of the prevention of this STD. Infected people should be advised on the best directions to follow, trying to prevent the spread of this disease.
