Summary
Ten cases of tropical spastic paraparesis (TSP) were identified in Brazil, exhibiting typical neurological symptoms. Further investigation is needed to confirm the suspected retrovirus (HTLV-I) as the cause.
Area of Science:
- Neurology
- Infectious Diseases
- Epidemiology
Background:
- Tropical spastic paraparesis (TSP) is a neurological disorder with significant impact.
- Previous research suggests a retroviral etiology, specifically Human T-lymphotropic virus type 1 (HTLV-I).
- Limited data exists on TSP cases in Northeastern Brazil.
Purpose of the Study:
- To present and characterize ten potential cases of TSP in Ceará, Northeastern Brazil.
- To describe the clinical manifestations and preliminary laboratory findings.
- To highlight the need for etiological investigation, particularly for HTLV-I.
Main Methods:
- Clinical case series presentation.
- Detailed neurological examination to identify characteristic TSP symptoms (lower limb weakness, spastic gait, hyperreflexia, bladder dysfunction, posterior column signs).
- Exclusionary laboratory tests to rule out other spinal cord pathologies (compressive, infective, degenerative, demyelinating).
Main Results:
- Ten patients presented with classic TSP symptoms and signs.
- Demographic profile: ages 21-59, Black ethnicity, lower social class, slight female predominance.
- Laboratory tests excluded alternative spinal cord lesions.
- Etiological confirmation of HTLV-I was not possible due to technical limitations.
Conclusions:
- The presented cases are consistent with tropical spastic paraparesis (TSP).
- The study underscores the potential presence of TSP in Northeastern Brazil.
- Confirmation of Human T-lymphotropic virus type 1 (HTLV-I) as the causative agent requires further investigation.
