Early-Onset HTLV-1-Associated Myelopathy/Tropical Spastic Paraparesis [PDF]
Background: Vertical transmission of HTLV-1 could lead to the early development of HTLV-1-associated myelopathy/tropical spastic paraparesis (HAM/TSP). This significantly affects quality of life and increases morbimortality.

Morbidity and Mortality Among People Living With HTLV-1: A 30-Year Retrospective Analysis in a Brazilian Cohort. [PDF]
ABSTRACT HTLV‐1 infection is a chronic condition associated with the development of malignancies, inflammatory, and neurological disorders. In this study, the causes of hospitalization and mortality were assessed in a cohort of 508 individuals living with HTLV‐1 followed over a 30‐year period. Overall mortality was 8.5% in this population and increased

Clinical Characteristics of Parkinsonism in HTLV-1-Associated Myelopathy. [PDF]
ABSTRACT Objective Human T‐lymphotropic virus type 1 (HTLV‐1)‐associated myelopathy/tropical spastic paraparesis (HAM/TSP) is the classic neurological manifestation of HTLV‐1 infection; however, this virus has also been associated with other neurological disorders. Concurrent parkinsonism is relatively rare and presents diagnostic challenges.

Cerebrospinal Fluid From Patients With HTLV-1-associated Myelopathy/Tropical Spastic Paraparesis (HAM/TSP) With Rapid Evolution Affects Mitochondrial DNA Transcription and Network Organization in Human Glioblastoma Cells. [PDF]
ABSTRACT Human T‐lymphotropic virus 1 (HTLV‐1)‐associated myelopathy/tropical spastic paraparesis (HAM/TSP) is a progressive neurodegenerative disease affecting motor and sensory functions. While alterations in cerebrospinal fluid (CSF) have been used to identify disease biomarkers, the effects of such modified CSF on CNS cells remain unexplored.
