Abstract
In Thailand, the anti-HIV screening in the donor blood was started in 1987 and was compulsory nationwide in February 1989. Sixty-six hemophilia A and 10 hemophilia B patients who received approximately six million units of factor VIII and IX in the form of fresh frozen plasma, frozen cryoprecipitate, cryoprecipitate removed plasma, fresh dry plasma and factor concentrate during 1976 to 1991 were tested for anti-HIV since 1987. The age ranged from 1-39 year (mean +/- SD = 15 +/- 7.3). The anti-HIV test was performed by ELISA and/or gel agglutination and confirmed by Western blot analysis. The patients would be checked 1-2 times per year and as necessary. A total of 174 tests for the first, second, third, fourth, fifth and sixth tests were studied in 76, 49, 27, 14, 5 and 3 patients respectively during 1987 to 1991. The prevalence of HIV seroconversion in the year 1987, 1988, 1989, 1990 and 1991 was 2.2% (1/45), 1.9% (1/53), 1.6% (1/63), 1.5% (1/67) and 3.9% (3/76) respectively. Three HIV seroconversion were found in the first, fourth and fifth anti-HIV test in 3 hemophilia A patients who received massive infusion of blood components during orthopedic corrective surgery. One case of HIV seroconversion found in 1987 was transmitted by HIV unscreened blood while 2 cases in 1991 by anti-HIV seronegative blood whose donors were in the window period of HIV infection. The prevalence of HIV seroconversion in Thai hemophiliacs is much lower than those in western countries.(ABSTRACT TRUNCATED AT 250 WORDS)
