Viral antibodies in the sera from patients with Parkinson disease.
An assay of antibodies to 15 various viruses and mycoplasma pneumoniae was performed on the serum specimens from 441 patients with Parkinson disease and from 443 healthy controls matched by sex, age, and place of residence, or from a representative group of these matched pairs. The main finding was a higher herpes simplex complement-fixing antibody level in patients with Parkinson disease than in controls. Patients with Parkinson disease had higher herpes simplex antibody titers more often than did their matched controls, and the matched controls, respectively, had low titers more often than the patients. The mean herpes simplex antibody titer (log2) of the patients (4.9) was significantly higher than that of controls (4.6) (p less than 0.01). This difference was also demonstrable when matched pairs were analysed for paired differences of herpes simplex antibody titers. For other viral CF and HI antibodies studied and for mycoplasma pneumoniae CF antibody, there were no significant differences either in the mean titers or in the distribution of individual titer values between the patients with Parkinson disease and the matched controls.
