RESUMO
O vírus linfotrópico das células T humanas do tipo 1 (HTLV-1) é o agente etiológico da mielopatia associada ao HTLV / paraparesia espástica tropical (HAM / TSP ), que ocorre em menos de 5 % dos indivíduos infectados. A resposta imune controla parcialmente a infecção, porém pode estar ligada a patogênese da doença. O objetivo deste estudo foi caracterizar fenotipicamente as subpopulações de linfócitos T, em pacientes assintomáticos e com diagnóstico de HAM/TSP. Foram avaliados 103 pacientes acompanhados no Centro de HTLV da Escola Bahiana de Medicina e Saúde Pública (EBMSP) e 19 controles não infectados. Os pacientes foram categorizados de acordo com o grau de certeza do diagnóstico de HAM/TSP possível (Ps), provável (Pb) e definido (D), além de pacientes assintomáticos (ASS). O perfil fenotípico (CD25, CD45RA, CD45RO, HLA-DR, CD25, CCR-7, CD62L)...
ABSTRACT
The human T-cell lymphotropic vírus type 1(HTLV-1) is the etiological agent of HTLV- associated myelopathy/ Tropical spastic paraparesis(HAM/TSP), wich occurs in less then 5% of the infected individuals. The immune response partially controls the infection, but may be linked to the pathogenesis of disease. The aim of this study was to characterize phenotipically T lymphocyte subpopulations in asymptomatic and in patients diagnosed with HAM/TSP. We evaluated 103 patients treated at the center for HTLV of Bahia School of Medicine and Public Health (EBMSP) and 19 uninfected controls. Patients were categorized as asymptomatic and according to the degree of certainty of the diagnosis of HAM/TSP Possible(Ps), Probable(Pb) and Definite(D). The phenotypic profile (CD25, CD45RA, CD45RO, HLA-DR, CCR-7, CD62L)...
