Confirming the presence of HTLV-1 infection and the absence of HTLV-2 in blood donors from Arequipa, Peru

Abstract: SuMMarYEpidemiological studies conducted in Peru disclosed HTLV-1 to be prevalent in different ethnic groups, and found HTLV-2 in some Amazonian Indians and in men who have sex with men. No data concerning HTLV-1/2 infection in blood donors from Arequipa, a highlands region in southern Peru, is available. We searched for the presence of HTLV-1 and HTLV-2 antibodies in 2,732 serum samples obtained from blood donors from this geographic area. HTLV-1/2-specific antibodies were detected using an enzyme-linked immu… Show more

“…In Peru, a real multiethnic country mainly inhabited by Mestizos and Amerindians, HTLV-1 prevalence in blood donors ranges from 1.2 to 1.7% depending on the region (Quispe et al, 2009) and from 1.3 to 3.8% in pregnant women or in the adult general population (Zurita et al, 1997; Sanchez-Palacios et al, 2003; Alarcon et al, 2006). Furthermore several large series of TSP/HAM and ATL have been reported (Gotuzzo et al, 2004; Beltran et al, 2011).…”

“…En Latinoamérica, las tasas de seropositividad para HTLV-1 entre donantes de sangre alcanza 0,1 a 2%. En el Perú, desde Junio de 1998 el Ministerio de Salud ha dispuesto el despistaje de HTLV-1 obligatorio en los bancos de sangre entre los donantes de sangre con lo cual se evitan aproximadamente 4000 transfusiones infectadas por año (2,25,26) Por lo tanto, es poco probable que en nuestra paciente, la transmisión del virus se haya producido por esta vía, y más bien creemos que la procedencia de la paciente de una zona de alta endemicidad para el HTLV-1 como es Ayacucho con patrones culturales que alientan la lactancia materna prolongada hayan sido determinantes para la infección viral.…”

“…De acuerdo con estos autores, el Perú es un área endémica de HTLV-1, dado que la prevalencia entre donantes de sangre, gestantes, trabajadoras sexuales, homosexuales varones y varones privados de libertad en varias partes del país se encuentra entre 1 a 7% (516,17) .…”

“…En todos los estudios publicados (5,–13,17,18) , excepto dos (16,17) , la prevalencia encontrada ha sido mayor al 1%. Uno de ellos, realizado en 370 pobladores quechuas voluntarios residentes en Cusco y Quillabamba, encontró una prevalencia total del 5,1%; en este estudio la prevalencia en gestantes sanas es de 2,3% (5 de 211 gestantes) (5) .…”
