Fulminant Myelopathy following Neurogenic Proximal Weakness Associated with Human T-Cell Lymphotropic Virus Type I Infection

Study of the Association Between Human T-cell Lymphotropic Virus Type I Infection and Lichen Planus

[Human T-Lymphotropic Virus Type I-Associated Myelopathy].

Human T-lymphotropic virus type I (HTLV-I)-associated myelopathy (HAM) is a chronic progressive myelopathy that is characterized by spastic paraparesis with bladder dysfunction that is derived from bilateral pyramidal tract involvement and neurogenic bladder, respectively. The primary neuropathological feature of HAM is chronic inflammation in the spinal cord, mainly the lower thoracic cord, wh...

Effects of Danazol on Clinical Improvement of Patients with Human T-cell Lymphotropic Virus Type I Associated Myelopathy/Tropical Spastic Paraparesis (HAM/TSP ): A Placebo-Controlled Clinical Trial

T-lymphotropic virus type 1-associated myelopathy

HTLV-1 Tax expression exerts an inhibitory effect on the Foxp3 transcription factor in CD4+CD25+ T-regulatory cells (Treg). For a better understanding of the role of Tax mRNA in the gene expression of cellular markers we measured Tax, Foxp3, CTLA4, GITR, TGF-β, and IL-10 mRNA in Treg cells of 50 patients with human T-lymphotropic virus type 1 (HTLV-1)-associated myelopathy/tropical spastic para...

Juvenile human T lymphotropic virus type 1-associated myelopathy.

We report the cases of 5 adolescents with human T lymphotropic virus type 1-associated myelopathy/tropical spastic paraparesis, acquired in all but 1 case from the mother. The first symptom in all patients was difficulty in running, which was present for many years before the final diagnosis was made. Follow-up showed an indolent progression, regardless of treatment strategy.
