Short or damaged telomeres have been implicated in degenerative conditions. We hypothesized that analysis of telomere length (TL) in human T-cell lymphotropic virus (HTLV) infection and HTLV-associated neuropathy might provide clues to the etiology of HTLV-associated disease and viral dynamics. A subset of 45 human T-cell lymphotropic virus type 1 (HTLV-1), 45 human T-cell lymphotropic virus ty...

Crusted scabies, formerly known as Norwegian scabies is uncommon presentation of that may occur in the association with an immunosuppressive status. The article aims to present a case report which male patient HTLV-1 carrier status admitted for investigation eczematous and crusted chronic skin lesions submitted dermatologic evaluation biopsy considering hypothesis cutaneous form lymphoma associ...

SIRIn a recent review of the infectious complications of human T-cell lymphotropic virus type I (HTLV-I) infection, Marsh [1] suggested that those individuals infected with HTLV-I may be at increased risk of tuberculosis. This risk may be due to reduced delayed-type hypersensitivity to PPD in asymptomatic patients infected with HTLV-l. Up to 14% of the population in Papua New Guinea are infecte...

A distinct clinical entity of uveitis associated with human T lymphotropic virus type 1 (HTLV-I) has been reported previously. During the period between January 1989 and April 1992, 93 patients were observed with HTLV-I uveitis and a significant correlation was found between Graves' disease and HTLV-I uveitis. Sixteen of the 93 patients with HTLV-I uveitis (17.2%) had a previous history of Grav...

While human T-lymphotropic virus type I (HTLV-I) proviral genome is readily detected in leukemic lymphocytes from adult T-cell leukemia patients, viral antigens or viral RNA are not expressed unless these cells are cultured. To address the problem of possible restriction mechanism of HTLV-I replication, we studied the methylation state of provirus in four HTLV-I transformed cell lines. These ce...

Human T-cell lymphotropic virus type 1 (HTLV-1) is endemic in many parts of the world and is primarily transmitted through sexual intercourse or from mother to child. Sexual transmission occurs more efficiently from men to women than women to men and might be enhanced by sexually transmitted diseases that cause ulcers and result in mucosal ruptures, such as syphilis, herpes simplex type 2 (HSV-...

We report the cases of 5 adolescents with human T lymphotropic virus type 1-associated myelopathy/tropical spastic paraparesis, acquired in all but 1 case from the mother. The first symptom in all patients was difficulty in running, which was present for many years before the final diagnosis was made. Follow-up showed an indolent progression, regardless of treatment strategy.

Human T-cell lymphotropic virus type II is a retrovirus endemic in Amerindian communities throughout the American continent, although some Amerindian groups that apparently emerged from the same ethnic root as HTLV-II carriers do not secrete antibodies against the virus and show very low prevalence for human T-cell lymphotropic virus type I. In this study, sera from 487 Amazonian amerinds were ...
