Human immunodeficiency virus detection: correlation with clinical progression in the Edinburgh haemophiliac cohort.
HIV p24 antigenaemia and virus detection in cultures of peripheral blood lymphocytes were examined in 16 of 18 haemophiliacs infected with HIV by a single batch of Scottish National Blood Transfusion Service factor VIII concentrate. Six (38%) had p24 antigenaemia and 11 (69%) had positive lymphocyte cultures. All seven patients with serious HIV disease (CDC group IV) had positive lymphocyte cultures whereas four (57%) had p24 antigenaemia. Four of nine (44%) patients with asymptomatic HIV disease (CDC groups II and III) had positive cultures and two (22%) had p24 antigenaemia. Twenty-eight of 36 samples from the symptomatic group were HIV culture positive compared with nine of 30 samples from the asymptomatic group (P less than 0.001). None of 14 antibody negative haemophiliacs who also received the implicated batch of factor VIII had p24 antigenaemia or positive HIV cultures. The ability to detect HIV in cultured lymphocytes correlates with the clinical severity of HIV disease in this cohort.
