    Abstract:
    Human T cell leukaemia virus (HTLV), HTLV proviral DNA, and antibodies to HTLV or a related agent have recently been detected in patients with acquired immunodeficiency syndrome (AIDS). Antibodies against HTLV-related antigens were assayed by means of indirect living cell immunofluorescence of HTLV-infected cells in sera recently collected from Georgia haemophiliacs and in sera collected between 1976 and 1981 from New York haemophiliacs. 5 of 45 Georgia haemophiliacs and 8 of 48 New York haemophiliacs had antibodies to HTLV-associated cell membrane antigen (HTLV-MA). None of the control Georgia patients on haemodialysis or with chronic hepatitis had detectable antibodies. The 5 haemophiliac patients from Georgia with HTLV-MA had significantly fewer T4 lymphocytes than similar HTLV-MA-negative patients. There were no other significant immunological differences between these groups. These data suggest that transfusions with blood products may expose haemophiliacs to a substantial risk of acquiring HTLV or a related virus.
