Interferon Beta-1a Improves Urinary Symptoms, Reduces Proviral Load, and Modifies the Immune Response in a Patient with HAM/TSP

P178: Can Human T-Lymphotropic Virus Proviral Load Predict the Severity of Clinical Features in HAM/TSP Patients?

HTLV-1 is the causative agent for a neurologic disease named HTLV-I- associated myelopathy/tropical spastic paraparesis (HAM/TSP). Paraparesis of the lower limbs which appears gradually is the most common clinical feature of this disease. The indirect involvement of the nervous system by lymphocytes is more probable than the direct attack of the virus to the neurons. The proviral load (PVL) is ...

P 56: Inhibitory Effects of Curcumin, a Regulator of CD4+ T Helper Cell, on HTLV-1-Associated Myelopathy/Tropical Spastic Paraparesis (HAM/TSP)

Human T-lymphotropic virus type I (HTLV-1) is an endemic virus in Iran and other regions that is associated with multiple diseases including adult T-cell leukemia/ lymphoma and a chronic debilitating neuroinflammatory disease, HTLV-1-associated myelopathy/tropical spastic paraparesis (HAM/TSP). HAM/TSP is seen in approximately 2% of HTLV-1-infected people with symptoms such as back pain, weakne...

P 130: The Role of Host T- Cell Lymphocyte in Immunopathogenesis of HTLV-I-Associated Myelopathy/Tropical Spastic Paraparesis

Human T-cell lymphotropic virus type 1 (HTLV-1) is associated with adult T-cell leukemia/lymphoma (ATL) and HTLV-1-associated myelopathy/tropical spastic paraparesis (HAM/TSP). Only a limited percentage of infected individuals develop disease in response to the virus while the majority remain asymptomatic and HAM/TSP is the most common clinical manifestation of the virus. HAM/TSP is an inflamma...

Evaluation of HTLV-1 activity in HAM/TSP patients using proviral load and Tax mRNA expression after In Vitro lymphocyte activation

Objective(s):HTLV-1 is the first human retrovirus that has been recognized and is associated with HAM/TSP and ATLL. Studies have shown that less than five percent of HTLV-1 infected carriers develop HAM/TSP or ATLL and about ninety-five percent remain asymptomatic. Therefore, the proviral load with Tax may affect cellular genes such as cytokines and oncogenes, as well as involve in pathogenicit...
