Human T Lymphotropic Virus Type 1-Associated Myelopathy/Tropical Spastic Paraparesis in an HIV-Positive Patient Coinfected with Human T Lymphotropic Virus Type 2 Following Initiation of Antiretroviral Therapy

Frequency of Human T-Cell Lymphotropic Virus (HTLV) Type 1 and 2 Infection in HIV Infected Patients

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...

Clinical Pathophysiology of Human T-Lymphotropic Virus-Type 1-Associated Myelopathy/Tropical Spastic Paraparesis

Human T-lymphotropic virus type 1 (HTLV-1), a human retrovirus, is the causative agent of a progressive neurological disease termed HTLV-1-associated myelopathy/tropical spastic paraparesis (HAM/TSP). HAM/TSP is a chronic inflammatory disease of the central nervous system and is characterized by unremitting myelopathic symptoms such as spastic paraparesis, lower limb sensory disturbance, and bl...

Incidence of Human T-Lymphotropic Virus Type 1 (HTLV-1) among Blood Donors from Ilam, Iran

Evaluating the Frequency of Human T-Lymphotropic Virus Type 1 Infection in Iranian Population

Background: Human T-cell lymphotropic viruses 1 (HTLV1) is endemic in specific regions. We aimed to determine the prevalence of HTLV I infection among blood donors in southeast Iran.   Methods: This cross-sectional study was conducted between April 2005 and March 2015. Sera were collected from blood donors and were tested for the presence of HTLV1 specific antibody using ELISA. Reactive sample...

Detection of human T-lymphotropic virus type I p40tax protein in cerebrospinal fluid cells from patients with human T-lymphotropic virus type I-associated myelopathy/tropical spastic paraparesis.

We investigated the role of viral transcripts of human T-lymphotropic virus type I (HTLV-I) in the cerebrospinal fluid (CSF) cells and peripheral blood mononuclear cells (PBMCs) of patients with human T-lymphotropic virus type I-associated myelopathy (HAM)/tropical spastic paraparesis (TSP). To detect the HTLV-I p40tax protein, we developed a new sensitive method of immunohistochemistry combine...
