Abstract:
To date, 271 cases of HTLV1-associated paraplegia have been observed in Martinique (French West Indies). The clinical picture consisted mostly in a spastic paraparesis or paraplegia with sphincter disturbances (80%) and lower limbs pains (60%). The severity of the disease appeared variable: after a mean disease duration of 6.5 years, 40% of the patients could walk without help, 35% used a single crutch, and 25% used a couple of crutches or were confined to a wheelchair. A variable neuromuscular component was observed in 70 cases (25.4%). In 38 cases, the peripheral signs (SIGNS) or the myositis were only mild. In contrast, 25 patients presented with severe amyotrophy evoking amyotrophic lateral sclerosis, and 7 other had features of dermatopolymyositis. Lastly, an extra-neural spreading of the disease was extremely frequent, including lymphocytic alveolitis (76%), sicca syndrome (69%) and more rarely uveitis, arthritis or vasculitis.
Insights
Human T-lymphotropic virus type 1 (HTLV1) causes a variable myelopathy in Martinique, often accompanied by neurological and systemic symptoms. Early detection and management are crucial for patients with HTLV1-associated myelopathy.
Area of Science:
- Neurology
- Infectious Diseases
- Epidemiology
Context:
- Human T-lymphotropic virus type 1 (HTLV1) infection is endemic in Martinique.
- HTLV1-associated myelopathy (HAM) is a significant neurological complication in the region.
- A substantial number of cases have been documented, highlighting the public health burden.
Purpose:
- To describe the clinical spectrum and progression of HTLV1-associated paraplegia in Martinique.
- To investigate the frequency and nature of neuromuscular involvement.
- To document the prevalence of extra-neural manifestations associated with HTLV1.
Summary:
- 271 cases of HTLV1-associated paraplegia were identified in Martinique.
- Clinical presentation commonly includes spastic paraparesis/paraplegia, sphincter disturbances, and lower limb pain.
- Disease severity varies, with a significant proportion experiencing mobility impairment over time.
- Neuromuscular involvement (e.g., amyotrophy, myositis) and extra-neural spread (e.g., alveolitis, sicca syndrome) are frequent.
Impact:
- Provides crucial epidemiological data on HTLV1-associated myelopathy in a specific geographic area.
- Highlights the diverse clinical manifestations, aiding in diagnosis and patient management.
- Emphasizes the systemic nature of HTLV1 infection beyond neurological symptoms.
- Informs public health strategies for prevention and control of HTLV1 in endemic regions.
