En el presente estudio describimos y caracterizamos la distribución geográfica de los casos positivos confirmados a HTLV-1 y 2 de pacientes peruanos con diagnóstico presuntivo entre 2019 y 2021. De un total de 555 muestras positivas confirmadas, 546 (98,4%) fueron HTLV-1 y 9 (1,6%) HTLV-2. Además, 22...
Resumen La leucemia/linfoma a células T del adulto (ATLL) es una enfermedad hematológica causada por el virus linfotrópico T humano tipo 1 (HTLV-1) que se desarrolla luego de 20 años de incubación, preferencialmente cuando la infección se adquiere por transmisión vertical. Este tiempo se reduce de...

Abstract INTRODUCTION: We investigated the prevalence of human T-cell lymphotropic virus types 1 and 2 (HTLV-1/2) infection in patients with hematological diseases from the western Amazon region of Brazil. METHODS: Samples from 306 patients were submitted for the molecular diagnosis of HTLV-1/2 infecti...
Abstract INTRODUCTION: Brazil ranks first in the number of HTLV-1/-2-infected individuals worldwide. The high morbidity and mortality of HTLV-1-associated diseases, especially following infection in infancy, requires strong action to reduce vertical transmission. METHODS: To facilitate the appraisal of...
Abstract INTRODUCTION We present a data analysis and review of recent studies regarding the laboratory diagnosis of human T-lymphotropic virus 1 and 2 (HTLV-1/2) infections in Brazil. METHODS Target populations, available diagnostic serological assays (screening and complementary tests), molecular as...
Abstract This article addresses the Human T-lymphotropic virus (HTLV). This subject comprises the Clinical Protocol and Therapeutic Guidelines for Comprehensive Care for People with Sexually Transmitted Infections, published by the Brazilian Ministry of Health. HTLV-1/2 infection is a public health probl...
Resumen Por ser el Perú un país endémico de HTLV-1, es importante conocer la confiabilidad de las marcas comerciales para el diagnóstico más usadas en nuestro país. En el presente estudio, evaluamos dos marcas comerciales de pruebas de ELISA (Biokit y Wantai) para la detección de anticuerpos contr...
Difficulties in confirming and discriminating human T-cell lymphotropic virus type 1 (HTLV-1) and HTLV-2 infections by serological Western blot (WB) assays (HTLV Blot 2.4; MP Biomedicals) have been reported in Brazil, mainly in HIV/AIDS patients, with a large number of WB-indeterminate and WB-positive bu...
Abstract INTRODUCTION: The human T-lymphotropic virus type 1 (HTLV-1) has a single-stranded RNA genome and expresses specific proteins that have oncogenic potential. Approximately 15 to 20 million people worldwide have been infected by this virus. Changes in protein or gene expression are the effects of...

The human T-cell lymphotropic virus type 1 (HTLV-1) is a retrovirus that infects about 20 million people worldwide and causes immune-mediated diseases of the nervous system. The classical neurological presentation of HTLV-1 infection is the so-called HTLV-1-associated myelopathy/tropical spastic parapare...
