AB Cytomegalovirus (CMV) antibody profiles were studied in 25 HIV-infected
patients over periods of up to 56 months. Specific antibodies against
CMV antigen components were monitored by complement-fixation (CF) test,
EIA, Western blot and a neutralization assay. Three subjects remained
CMV seronegative throughout the study. Marked fluctuations were observed
in anti-CMV antibodies assayed by the CF test as compared to a control
group. Fluctuations on immunoblots of purified virion antigens were also
observed in the HIV-infected patients; neutralizing antibodies and
anti-CMV nucleocapsid antibodies showed less variability. Seven of 22
individuals exhibited an increase in CF-test titre of up to 64-fold
without clinically apparent CMV disease. On Western-blot testing of IgG
reactivity with disrupted virions, ten individuals exhibited increasing
reactivity to pp65, and only three of these also showed a titre rise in
the CF test. In contrast, 7 of 22 showed low reactivity to the pp28
antigen. The homosexual patient group exhibited the highest levels of
anti-CMV antibody. In conclusion, many asymptomatic HIV-infected
subjects showed fluctuations at different levels of their antibody
response to CMV, thought to be indicative of CMV
reactivation/reinfection. Western-blot findings indicated that some CMV
antibodies increased in level while others were lost.
