Cytomegalovirus-specific cell-mediated immunity in lower-socioeconomic-class adolescent women with local cytomegalovirus infections.
The factors that regulate cytomegalovirus (CMV) excretion from the genitourinary tract are poorly understood. To assess the role of cell-mediated immunity in such excretion, a CMV-specific mononuclear blastogenesis assay was used to study a predominantly lower-socioeconomic-status population of 92 healthy nonpregnant adolescent women who also had CMV complement-fixing antibody titers and viral cultures of cervix, urine, saliva, and blood performed. Eighteen were studied more than once. No blood cultures were positive and no seroconversions were noted. There was no significant difference for frequency or degree of systemic CMV-specific blastogenesis between the 20 who were culture positive and the 41 who were seropositive but culture negative, although 40% of the culture-positive group and 27% of the seropositive, culture-negative group lacked CMV-specific blastogenesis. One of 31 seronegative subjects displayed CMV-specific blastogenesis. No systematic deficits were noted in any groups or individuals for E rosette number or mitogen response, though some isolated significant differences among groups for mitogen responses existed. Local CMV excretion in the study population was not related to systemic CMV-specific mononuclear blastogenesis.
