Natural history of primary Epstein-Barr virus infection in children of mothers infected with human immunodeficiency virus type 1

The natural history of Epstein-Barr virus (EBV) infection in 556 infants bo rn to 517 human immunodeficiency virus (HIV) type I-infected mothers was st udied in a prospective, multicenter, cohort study. HIV-1-infected children had a cumulative EBV infection rate similar to HIV-1-uninfected children at age 3 years (77.8% vs. 84.9%) but had more frequent oropharyngeal EBV shed ding (50.4% vs. 28.2%; P <.001), The probability of shedding decreased with longer time from EBV seroconversion and was similar to that of HIV-1-uninf ected children 3 years after seroconversion, HIV-1-infected children identi fied as rapid progressors shed EBV more frequently than nonrapid progressor s (69.4% vs. 41.0%; P =.01), HIV-1-infected children with EBV infection had higher mean CD8 cell counts. EBV infection did not have an independent eff ect on mean CD4 cell counts, percent CD4, IgG levels, HIV-1 RNA levels, lym phadenopathy, hepatomegaly, or splenomegaly, Early EBV infection is common in children born to HIV-1-infected mothers. Children with rapidly progressi ve HIV-1 disease have more frequent EBV shedding.
