PURPOSE We conducted a longitudinal analysis of human T lymphotropic virus type I (HTLV-I) viral markers in 28 Jamaican mothers and their children, who were monitored for a median of 6.2 years after the birth of the children. METHODS The HTLV-I provirus DNA load was measured using the Taqman system (PE Applied Biosystems). The HTLV-I antibody titer was determined using the Vironstika HTLV-I/I...
The present study was performed to clarify the relationship between human T cell lymphotropic virus type I (HTLV-I) infection and chronic inflammatory arthropathy. To determine the ability of HTLV-I to infect synovial cells and the effect on synovial cell proliferation, synovial cells were cocultured with the HTLV-I-producing T cell lines (MT-2 or HCT-1). After coculture with HTLV-I-infected T ...
T cell colonies were generated from the peripheral blood mononuclear cells (PBMC) of 10 patients with tropical spastic paraparesis/human T lymphocyte virus type I (HTLV-I)-associated myeloencephalopathy (TSP/HAM), two healthy HTLV-I carriers, and 17 healthy HTLV-I-seronegative subjects. PBMC were cultured in methylcellulose in the absence of added growth factors (spontaneous T cell colonies), o...
Adult T-cell leukemia (ATL) is neoplasm of the mature helper T lymphocytes and human T-cell lymphotropic virus type-I (HTLV-I) has been shown to be causative virus of ATL. Because HTLV-I integrates its provirus randomly into host chromosomal DNA, monoclonal integration of HTLV-I provirus indicates the clonal proliferation of HTLV-I-infected cells. Therefore, demonstration of clonality of HTLV-I...
HTLV-I-associated myelopathy (HAM/TSP) is the most common neurological manifestation of HTLV-I, causing progressive weakness, sensory disturbance, and sphincter dysfunction. Although motor disorders have been well described, few studies have associated cognitive disorders and HTLV-I infection. In areas endemic for HTLV-I infection, the differential diagnosis between HAM/TSP and other myelopathy...
It was observed in the city of Salvador, State of Bahia, the highest seroprevalence of human T cell lymphotropic virus type 1 (HTLV-I) infection in Brazil as demonstrated by national wide blood bank surveys. In this paper, we report results of an investigation of drug use and sexual behavior associated with HTLV-I infection among male and female injecting drug users (IDUs) in Salvador. A cross ...
BACKGROUND The aim of the study was to reassess the prevalence and characteristics of human T lymphotropic virus type I (HTLV-I)-associated Sjögren's syndrome (SS) and SS in HTLV-I-associated myelopathy (HAM) based on the American European Consensus Group (AECG) criteria in HTLV-I endemic area, Nagasaki prefecture. METHODS The 349 patients who underwent a minor salivary gland biopsy (MSGB) fo...
Mycosis fungoides (MF) is a rare form of cutaneous T-cell lymphoma that may be associated with human T-cell leukemia virus type I (HTLV-I) infection. Using the polymerase chain reaction, the HTLV-I pX region was constantly detected in the genomic DNA extracted from peripheral blood mononuclear cells (PBMCs) of an HTLV-I antibody-seronegative Egyptian MF patient enrolled in a study to isolate HT...
objective(s): htlvi-1 is the first human retrovirus with limited endemic regions in the world. the epidemiological studies have shown that the genetic background and immune response to the virus have a significant role in htlv-i-associated diseases. among the genes are involved in htlv-i infection, the role of human leukocytes antigen (hla) have been studied in different population. in the pre...
Natural antibodies in sera from Japanese individuals infected with HTLV-I do not recognize HTLV-III.
Seventy-one sera from Japanese individuals infected with human T cell leukemia virus type I (HTLV-I) were examined for the presence of antibodies to HTLV-III by an enzyme-linked immunosorbent assay (ELISA) and by a strip radioimmunoassay based on the Western blot technique. The sera were from 23 healthy carriers and from 48 patients, including 18 with smoldering adult T cell leukemia (ATL), 13 ...
