title: Human immunodeficiency virus infection in hemophiliac patients. A three-year prospective evaluation.
abstract: Thirty-seven heterosexual hemophiliac patients underwent prospective evaluation with clinical examinations, serologic studies for antibody to human immunodeficiency virus (HIV), and tests of immune function for an average of 37 months. At the time of entry into the study in 1982 to 1983, 18 subjects (49 percent) were already seropositive for HIV and 11 (30 percent) had persistent generalized lymphadenopathy. Seventy percent of the total population were clinically asymptomatic. In nine subjects, seroconversion occurred during the study such that 81 percent of the population was seropositive at the conclusion. During the same period, lymphadenopathy developed in six subjects, there was progression to AIDS-related complex (ARC) in four, and acquired immunodeficiency syndrome (AIDS) developed in one patient. Thus, at the end of the study, 54 percent were clinically asymptomatic, 32 percent had persistent lymphadenopathy, and 11 percent had ARC. Subjects who remained seronegative had received less factor concentrate than seropositive subjects, remained asymptomatic, and had normal results on tests of immune function. In those who had experienced seroconversion, there were decreased absolute numbers of CD4+ lymphocytes prior to seroconversion, and abnormalities of lymphocyte function developed after seroconversion. The development of persistent generalized lymphadenopathy was associated temporally with seroconversion. The presence of persistent generalized lymphadenopathy did not appear to be associated with an increased risk for AIDS in seropositive persons, since the condition of most hemophiliac patients with persistent generalized lymphadenopathy at the time of initial evaluation remained clinically and immunologically stable. In contrast to patients with persistent generalized lymphadenopathy, asymptomatic seropositive subjects had progressive abnormalities of lymphocyte function over time that were independent of the numbers of CD4+ cells in the peripheral blood.
