Resumo: | The present study describes HTLV seroprevalence in potential blood donors from the Brazilian state of Pará, and the sociodemographic characteristics of the infection in this state. This descriptive, retrospective, and cross-sectional study is based on secondary serological and sociodemographic data on potential blood donors who were rejected for presenting reactive results in the serological HTLV screening between January 2010 and December 2020. The mean HTLV seroprevalence was 0.2%. The highest frequency of reactivity was recorded in first-time donors, women, individuals over 30 years old that were single and had a relatively low level of education. There have been many advances since the discovery of HTLV, although it is still considered to be a neglected etiological agent in Brazil. Further research on data from hematological services will be necessary to refine regional infection profiles, which will be fundamental for the development of adequate prophylactic practises to control and prevent infection, as well the dissemination of information on the dangers of HTLV to the general population. |

Seroprevalence of the Human T Lymphotropic Virus (HTLV 1 and HTLV 2) in Blood Donor Candidates in the State of Pará, Northern Brazil Seroprevalencia del Virus Linfotrópico T Humano (HTLV 1 y HTLV 2) en Candidatos a Donación en el Estado de Pará, Norte de BrasilSoroprevalência do Vírus Linfotrópico T Humano (HTLV 1 e HTLV 2) em Candidatos a Doação no Estado do Pará, Norte do BrasilHTLV infectionBlood donorsSoroprevalência.Infecciones por DeltaretrovirusDonantes de SangreEstudios Seroepidemiológicos.Infecções por HTLVDoadores de sangueSeroprevalence.The present study describes HTLV seroprevalence in potential blood donors from the Brazilian state of Pará, and the sociodemographic characteristics of the infection in this state.

Por lo tanto, el objetivo del estudio fue determinar la seroprevalencia de HTLV en donantes de sangre en el Estado de Pará y describir las características epidemiológicas de esta infección. Es un estudio descriptivo, retrospectivo y transversal, basado en datos serológicos y epidemiológicos secundarios de donantes no aptos para la donación de sangre por presentar resultados reactivos en la prueba serológica para HTLV, de enero de 2010 a diciembre de 2020. La seroprevalencia fue de 0,2%. HTLV. La mayor frecuencia de reactividad se encontró entre mujeres, mayores de 30 años, solteras, con menor nivel educativo y donantes primerizas. Es fundamental más investigación en el área de los servicios regionales de hemoterapia y hematología, para contribuir a la definición de perfiles regionales de infección, fundamentales para el desarrollo de prácticas profilácticas en la prevención de la infección, y la difusión del conocimiento sobre los peligros del HTLV en la comunidad.Considerando a significativa soroprevalência média da infecção em doadores de sangue e a eficiente transmissão de HTLV por hemotransfusões, estudos de soroprevalência de HTLV entre doadores de sangue é de fundamental importância para revelar a situação específica da região em relação a este vírus, considerando que as regiões brasileiras apresentam distintas condições socioeconômicas, demográficas e culturais. Portanto o objetivo do estudo foi determinar a soroprevalência do HTLV em doadores de sangue do Estado do Pará, e descrever as características epidemiológicas desta infecção. É um estudo descritivo, retrospectivo e transversal, realizado a partir de dados secundários sorológicos e epidemiológicos de doadores inaptos para a doação de sangue por apresentarem resultados reativos no teste sorológico para HTLV, de janeiro de 2010 a dezembro de 2020. A soroprevalência foi de 0,2% de HTLV. A maior frequência de reatividade foi encontrada entre mulheres, idade superior a 30 anos, solteiros, com menor grau de escolaridade e doadores de primeira. É essencial mais pesquisas na área dos serviços regionais de hemoderapia e hematologia, para contribuir com a definição dos perfis regionais de infecção, fundamentais para o desenvolvimento de práticas profiláticas na prevenção da infecção, e a disseminação do conhecimento sobre os perigos do HTLV na comunidade.Research, Society and Development2022-03-09info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/2708210.33448/rsd-v11i4.27082Research, Society and Development; Vol. 11 No. 4; e1111427082Research, Society and Development; Vol. 11 Núm. 4; e1111427082Research, Society and Development; v. 11 n. 4; e11114270822525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIenghttps://rsdjournal.org/index.php/rsd/article/view/27082/23615Copyright (c) 2022 Carolina de Alcântara Maneschy; Katarine Antonia do Santos Barile; Jairo Augusto Américo de Castro; Maurício Koury Palmeira; Renata Bezerra Hermes de Castro; Carlos Eduardo de Melo Amaralhttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessManeschy, Carolina de AlcântaraBarile, Katarine Antonia do SantosCastro, Jairo Augusto Américo dePalmeira, Maurício KouryCastro, Renata Bezerra Hermes deAmaral, Carlos Eduardo de Melo2022-03-27T17:17:09Zoai:ojs.pkp.sfu.ca:article/27082Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:44:55.318827Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false |
