Neutralizing antibody to gB2 human cytomegalovirus does not prevent reactivation in patients with human immunodeficiency virus infection.
The incidence of human cytomegalovirus (CMV) genotype gB2 (UL55) is high in patients with human immunodeficiency virus (HIV) infection in the San Francisco Bay area of California. Virus neutralizing antibody (NAb) to human CMV strain Ad169, a gB2 laboratory strain, was measured prospectively in HIV-infected patients, with CD4 T-lymphocyte counts <200, who were at risk for CMV-associated disease. Patients were grouped according to CMV DNA copy number, as quantified by PCR, and presence or absence of CMV-induced retinitis. Mean NAb titres were similar in all patient groups and unrelated to either virus load or outcome of CMV infection. Both gB2 and mixtures of gB2 with other gB genotypes were represented in isolates from blood and/or urine, even in the presence of high titres of antibody to the gB2 genotype challenge virus.
