ABSTRACT
A survey of the spectrum of neurological syndromes encountered in Barbados was carried out to determine the pathogenic role of human T-lymphotropic virus (HTLV-I) infection in affected patients. Since 1989, patients with chronic neurological disorders were either recalled or were selected from new referrals to the neurology clinic at the Queen Elizabeth Hospital, Barbados. With the consent of patients, serum and CSF samples were tested for IgG antibodies to HTLV-I, using an enzyme-linked immunosorbent assay method. Positive results were confirmed by Western Immunoblotting at the CAREC Laboratories, in Trinidad. Only patients native to Barbados and the Eastern Caribbean were included in the survey. Twenty-nine (29) of 170 patients tested were serpositive for HTLV-I antibodies 18(62 percent) of the HTLV-I-positive patients had tropical spastic paraparesis (TSP). Of 21 seropositive patients who also had CFS-positive antibodies status, 16(76 percent) had TSP, 2(9.5 percent) adult T-cell leukaemia/lymphoma (ATLL), and 3 (14 percent) polymyositis, including 2 with an atypical clinical profile. HTLV-I seronegative patients included 12 (8.5 percent) with ataxia, 19(13.5 percent) with a relapsing/remitting sydrome characteristic of multiple sclerosis, 8(5.5 percent) with idiopathic intracranial hypertension and 8(5.5 percent) with stroke. HTLV-I positive associated neurological diseases in Barbados consist primarily of myelopathy (TSP). Some cases present more complex patterns of neurlogical dysfunction, associated with polymyositis.
