ABSTRACT
Anterior horn cell degeneration has only been noted occasionally in patients with tropical spastic paraparesis associated with human T-lymphotropic virus type I infection (HTLV-I). We report on three adult patients with HTLV-I associated polymyositis who had evidence of anterior horn cell degeneration. One patient had moderate proximal weakness in all 4 limbs, while 2 had mild upper limb weakness and profound proximal weakness in the lower limbs. Electromyographic findings indicated motor unit loss. Muscle biopsies in 2 patients showed features of denervation, as well as mono-nuclear inflammatory cell infiltration. HTLV-1 IgG antibodies were detected by enzyme-linked immunosorbent assay, and confirmed by Western-immunoblot, in serum and cerebrospinal fluid in all 3 patients. In two, cell cultures were established from peripheral blood lymphocytes and HTLV-1 antigen was identified by immunofluorescence and the ELISA antigen capture technique, using an anti-p 19 HTLV-1 mouse monoclonal antibody. These 3 cases illustrate the variety of neuromuscular disease, other than spastic paraparesis, that may occur in HTLV-1 infection. Anterior horn cell degeneration may coexist with HTLV-1 associated polymyositis and may make a significant contribution to the muscle atrophy observed in these cases (AU)
