Abstract: | To confirm an association between cytomegalovirus (CMV) infection and the presence of antibodies to Smith (Sm), to ribonucleoprotein
(RNP), and to a component of the U1 ribonucleoproteins (U1-70 kD), we measured antibodies to these protein antigens using
an enzyme immunoassay and an immunoblot. The antibodies were measured in the sera of 80 healthy subjects, one-half of whom
were naturally CMV seropositive and one-half were CMV seronegative, and in eight subjects immunized with a live attenuated
strain of CMV. None of the vaccinees developed antibodies to Sm, to RNP, or to U1-70 kD at either 4 or 12 months after immunization.
Additionally, there was no statistically significant association between levels of antibodies to Sm or to RNP and between
sera obtained from vaccinees, natural CMV seropositive individuals, and CMV seronegative individuals. One CMV seropositive
serum and one CMV seronegative serum tested positive for antibodies to U1-70 kD. These data indicate that neither wild-type
infection nor the live-attenuated Towne vaccine frequently induce autoantibody production. |
