The sera and the CSFs from 157 Multiple Sclerosis (MS) patients and 43 other neurological diseases (OND) cases have been evaluated for the presence of HTLVI antibodies. A commercial passive agglutination assay (PPA), an indirect fluorescence assay (IFA), and a Western Immunoblotting (WIB) performed in our laboratories have been employed. No OND samples showed HTLVI antibodies, while 14 sera and 1 CSF from MS patients resulted positive by PPA and 4 sera were positive with the IFA. When tested with WIB 6 MS sera showed a reactivity against one or more HTLVI proteins. Our results lead us to affirm that in a small number of MS patients, when sensitive tests are employed, it is possible to observe an antibody response toward proteins that share one or more epitope with HTLVI antigens.
