AB INTRODUCTION--In patients with human T-cell lymphotropic virus type 1
(HTLV-1) associated myelopathy/tropical spastic paraparesis (HAM/TSP),
we investigated the significance of HTLV-1 specific antibodies in the
cerebrospinal fluid (CSF). MATERIAL AND METHODS--The quantities of
HTLV-1 specific immunoglobulin G (IgG) in paired CSF and serum were
evaluated by a sensitive enzyme immunoassay (EIA). The specificity of
antiviral IgG was determined by radioimmunoprecipitation of HTLV-1
antigens. RESULTS--In 17 of 20 HAM/TSP patients, quantitative evaluation
by EIA supplied evidence for antiviral IgG synthesis within the CNS.
Radioimmunoprecipitation demonstrated IgG antibodies against HTLV-1
envelope and core proteins in all HAM/TSP CSF and sera tested. Regarding
the 3 sample pairs indeterminate in EIA for intrathecal synthesis, 2
showed stronger precipitation of HTLV-1 antigens by CSF IgG than by
equal amounts of serum IgG. CONCLUSION--Intrathecal antibody synthesis
specific for both HTLV-1 core and envelope antigens is common in
HAM/TSP, thus providing conclusive evidence for an immune response to
HTLV-1 within the CNS.
