At the end of 1984 a collaborative survey was carried out to determine the prevalence of infection with human T cell lymphotropic virus type III/lymphadenopathy associated virus (HTLV-III/LAV) and HTLV-I among 584 recipients of various blood products in Britain at that time. In 204 cases yearly point prevalence figures for infection were also obtained for 1978 to 1983. In 1984, 215 of 315 patie...

Human T cell lymphotropic virus type 1 (HTLV-1)-associated infective dermatitis (ID) is a chronic, severe and recurrent eczema occurring during childhood in patients vertically infected with HTLV-1. HTLV-1-associated myelopathy/tropical spastic paraparesia (HAM/ TSP) is slow and progressive. We report the case of an adolescent female from a non-endemic area for HTLV-1 who presents ID and, most ...

Adult T-cell Leukemia/Lymphoma (ATL) is a rare disease, related to human T-lymphotropic virus-1 (HTLV-1) and presented mainly in adulthood by generalised lymphadenopathy, hepatosplenomegaly, skin lesions and hypercalcaemia, with rare gastrointestinal and/or oral manifestations. We reported this case to raise awareness and demonstrate the therapeutic challenges of this rare disease. A 49-year-ol...

Human T-cell lymphotropic virus type I (HTLV-I) has been reported as the cause of a kind of endogenous uveitis (HTLV-I associated uveitis; HAU). We observed a case of episcleritis in a HTLV-I carrier with pigmentary retinal degeneration. HTLV-I infection might be associated with the development of episcleritis and pigmentary retinal degeneration. Patients with episcleritis or pigmentary retinal...

objective: the aim of this study was to investigate the existence of human t-lymphotropic virus type 1 (htlv-1) in subgingival plaque of htlv-1 seropositive pa-tients. materials and methods: a total of 18 patients including 13 females and fivemales, with a mean age of 37 years participated in this descriptive study. half of them were htlv-1 carriers and the others were in htlv-1 associated myel...

The human immunodeficiency virus type 1 (HIV-1) laboratory strains adapted to T-cell lines, as well as most syncytium-inducing primary isolates, replicate poorly in macrophages, which, beside CD4(+) T lymphocytes, are major targets of HIV-1. In the present work, we used a semiquantitative PCR-based technique to study viral entry into cells, kinetics of reverse transcription, and translocation o...

Mutation of the p53 tumor suppressor gene is a recurring event in a variety of human cancers. Wild-type p53 may regulate cell proliferation and has recently been shown to repress transcription from several cellular promoters. We studied the effects of wild-type and mutant human p53 on the human proliferating-cell nuclear antigen promoter and on several viral promoters including the simian virus...

Adult T-cell leukemia (ATL) is an aggressive lymphoid proliferation associated with the human T-lymphotropic virus type I (HTLV-I). The intraocular invasion of ATL is a rare event. A 75-year-old man without any systemic disease underwent uneventful cataract surgery of the right eye. On postoperative day 6, the patient presented with blurred vision due to severe vitreous opacity in the right eye...

Background and Objectives: Human T-cell lymphotropic viruses (HTLV) type 1 and 2 are retroviruses that share the same routes of transmission as human immunodeficiency virus (HIV). As a consequence of epidemiologic similarities, HIV and HTLV-1/2 co-infection is frequent. Due to the limited data, this study assessed the seroprevalence of HTLV-1/2 infections in HIV infected patients in Tehran, Ira...
