Abstract:
We describe the clinical and pathological studies in HTLV-I associated myelopathy (HAM)/tropical spastic paraparesis (TSP) patients with peripheral neuropathy as proven by sural nerve biopsy. Sural nerve pathology in HAM/TSP patients revealed that the most common type of pathologic change is a combination of both demyelination and remyelination and axonal degeneration and regeneration, and this change is modified by the complications. The pathologic changes were correlated with neither the duration of disease nor human T lymphotropic virus type I (HTLV-I) proviral load. This study suggests that peripheral nerves could be involved in HAM/TSP.
