Human T cell lymphotrophic virus type-1 infection is endemic in the Afro-Caribbean community in Britain, with carriage rates of about 3%. Although there is a long latency, carriers have a 1-5% chance of developing adult T cell leukaemia/lymphoma, a condition frequently complicated by marked and refractory hypercalcaemia, and with a poor prognosis. We present the case of an elderly Jamaican woma...

Sir, Adult T-cell leukemia/lymphoma (ATL) is a peripheral T-cell malignancy caused by human T-cell lymphotrophic virus type I (HTLV-I). The characteristic clinical features of ATL include generalized lymphadenopathy, leukemic cells of T-cell origin with highly convoluted nuclei, skin involvement, hypercalcemia and rapid progress of the clinical course. Relatively high rates of HTLV-I infection ...

As an acquired immunodeficiency, human immunodeficiency virus (HIV) infection is primarily responsible for opportunistic infections in infected patients. However, opportunistic infections also occur in individuals with human T cell lymphotrophic virus type 1 (HTLV-1) infection. Here, we report opportunistic infections in two Japanese HTLV-1-seropositive patients. The first patient was a 67-year...

Human T-cell lymphotropic virus type-I (HTLV-I) was the first human retrovirus associated with malignancy.  The prevalence of HTLV-I infection varies significantly in different regions of the world.  In this study, the prevalence of HTLV-I infection among ethnic Jews living in Shiraz, South of Iran, was investigated. 286 blood samples were obtained.  HTLV-1 antibody assay on serum samples was d...

Following infection by human T cell lymphotrophic virus-I (HTLV-I), high frequencies of polyclonal Tax11-19-reactive CD8(+) T cells can be detected in the peripheral blood. To investigate whether there are differences in the effector functions of these cells, we generated a panel of Tax11-19-reactive T cell clones by single cell sorting of HLA-A2/Tax11-19 tetramer binding CD8(+) T cells followe...

Background—We have previously reported that disseminated pulmonary Mycobacterium avium complex (MAC) infection is more common in human T lymphotrophic virus type I (HTLV-I) carriers than in non-carriers. However, the reason for this remains unclear. It has been shown that glycopeptidelipid (GPL), one of the lipid components of the cell envelope of MAC, is able to reduce the lymphocyte blastogen...
