Sera from 31 patients with lupus erythematosus, 31 controls matched by age and sex and 33 patients with connective tissue disorders other than SLE were examined for specific antibodies to 15 viral antigens by hemagglutination-inhibition tests. Complement-fixation tests were also employed t o measure

✦ Synopsis
Sera from 19 patients with Alzheimer's disease (AD) and 21 control subjects were studied by immunofluorescence and enzyme immunnoassay for antibody activity against various viruses and 12 self-and non-selfantigens. Total IgG mean level was significantly higher in the AD group; the IgG level was above 15 g/L in 52.8% of AD patients versus 14.3% of control subjects. Antiviral antibody titers showed no significant differences except for antibodies to herpes sim-plex virus-1 , which were increased in control group. In contrast, autoantibodies were more frequently found in AD patients, and the prevalence of antibodies to spectrin, peroxidase, and thyroglobulin was significantly increased.
Thus, in our series, autoimmune but not antiviral responses were heightened in at least 42% of AD patients (versus 9% of the control group) suggesting the existence of two subpopulations in the AD group.
