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...
OBJECTIVE(S) Few studies have shown the association between HTLV-I infection and coronary artery disease (CAD). HTLV-I has been detected in heart autopsies, particularly in lymphoma\leukemia cases. Mashhad and Neyshabour (Razavi Khorasan Province, Iran) are endemic regions for HTLV-I. Therefore, the present study was carried out to evaluate the impact of HTLV-I on CAD in Neyshabourian patients....
Background and Aims: Human T-lymphotropic virus (HTLV) is a human retrovirus which has been known to cause adult T-cell leukemia/lymphoma and some other inflammatory disorders. Patients with hereditary bleeding diseases are at high risk for these viruses. In this study, we evaluated serological HTLV-I/II infection among these patients in west Azerbaijan of Iran. Material and Methods: We stud...
Seven hundred and four HIV-1/2-positive, antiretroviral therapy (ART) naïve patients were screened for HTLV-1 infection. Antibodies to HTLV-1 were found in 32/704 (4.5%) of the patients. Each co-infected individual was matched with two HIV mono-infected patients according to World Health Organization clinical stage, age +/-5 years and gender. Key clinical and laboratory characteristics were com...
Infection of carriers of strongyloides by the human oncogenic retrovirus HTLV-1 significantly augments the number of larval parasites in the stools and impairs the action of anti-helminthic agents, resulting in an increase in immediate and longer term failure of therapy. The proliferation of cytokine type 1 secreting lymphocytes, the preferred target for viral infection, shifts the Th1/Th2 bala...
Background: A high prevalence of human T-cell lymphotropic virus type 1 (HTLV-1) infection among general population in the northeast of Iran has been reported. Multi-transfused patients are known as ‘at-risk’ group for the infection. This systematic review and meta-analysis was conducted to estimate the prevalence of HTLV-1 infection among Iranian multi-transfused patients. Materials and Meth...
background globally, almost 20% of cancers are related to infectious agents that can be prevented. oncogenicity refers to viruses that may cause cancers, more importantly in immunocompromised subjects such as transplant and hemodialysis patients. therefore, epidemiological studies are the first line for understanding the importance of these agents in public health, particularly, in mobile popul...
Human T-cell lymphotropic virus (HTLV) types 1 and 2 belong to the Oncorna group of retroviridae, a large family of viruses, grouped initially by pathogenic features, but later revised on the basis of genome structure and nucleotide sequence. HTLV-I was the first discovered human retrovirus to be associated with a malignancy in 1980. The malignancy, first described by Uchiyama and co-workers in...
Going back to their discovery in the early 1980s, both the Human T-cell Leukemia virus type-1 (HTLV-1) and the Human Immunodeficiency Virus type-1 (HIV-1) greatly fascinated the virology scene, not only because they were the first human retroviruses discovered, but also because they were associated with fatal diseases in the human population. In almost four decades of scientific research, both ...
The human T-lymphotropic virus type-1 (HTLV-1) is the cause of adult T cell leukaemias/lymphoma. Because thymic epithelial cells (TEC) express recently defined receptors for the virus, it seemed conceivable that these cells might be a target for HTLV-1 infection. We developed an in vitro co-culture system comprising HTLV-1+-infected T cells and human TECs. Infected T cells did adhere to TECs an...
