human t-cell lymphotropic virus type 1 (htlv-1) is associated with adult t-cell leukemia/lymphoma (atl) and htlv-1-associated myelopathy/tropical spastic paraparesis (ham/tsp). only a limited percentage of infected individuals develop disease in response to the virus while the majority remain asymptomatic and ham/tsp is the most common clinical manifestation of the virus. ham/tsp is an inflamma...

Desde o descobrimento e caracterização do retrovírus (HTLV-i) a sua associação com algumas neoplasias de células T periféricas, muitos avanços foram alcançados quanto aos aspectos etiopatológicos da leucemia/linfoma adulto (LLTA). Estudos soroepidemiológicos anti-HTLV-I realizados em diversas partes mundo demonstraram que: HTLV-I é agente etiológico LLTA paraparesia espástica tropical (TSP); te...

The human T-cell lymphotropic virus type I (HTLV-I) is associated with a chronic, progressive neurological disease known as HTLV-I-associated myelopathy/tropical spastic paraparesis. Screening for HTLV-I involves the detection of virus-specific serum antibodies by EIA and confirmation by Western blot. HTLV-I/II seroindeterminate Western blot patterns have been described worldwide. However, the ...

Screening of blood for human T-cell lymphotropic virus type 1 and type 2 (HTLV-1 and -2, respectively) is important to diagnose and prevent infection and ensure the safety of blood supplies. The Elecsys HTLV-I/II assay is a newly developed, electrochemiluminescence screening assay for the detection of HTLV-1/2 infection. The sensitivity and specificity of the Elecsys HTLV-I/II assay were determ...

Until now, serologic tests that distinguish the closely related human T-cell lymphotropic virus types I (HTLV-I) and II (HTLV-II) infections have not been available. Synthetic peptide assays, employing peptides derived from the core and envelope proteins of HTLV-I and HTLV-II (SynthEIA and Select-HTLV tests), were evaluated for the ability to serologically discriminate HTLV-I and HTLV-II infect...

The ocular manifestation of human T-cell lymphotropic virus type I (HTLV-I) infection has been recognized as a new clinical entity termed HTLV-I uveitis. In order to determine whether HTLV-I uveitis is associated with lymphocyte alveolitis, bronchoalveolar lavage (BAL) was carried out in 11 patients with HTLV-I uveitis, five asymptomatic HTLV-I carriers, 11 HTLV-I-negative patients with ocular ...

Background: A study was undertaken to investigate the pathogenesis of pulmonary involvement in human T lymphotropic virus type I (HTLV-I) carriers. Methods: The bronchoalveolar lavage (BAL) cell profile of 30 HTLV-I carriers (15 asymptomatic HTLV-I carriers (AHCs) and 15 symptomatic HTLV-I carriers (SHCs)) with chronic inflammatory diseases of respiratory tract and eight patients with HTLV-I as...
