Immunofluorescent Staining for the Measurement of Antibodies to Herpesvirus hominis

A laboratory based epidemiologic study was done to determine the possible relationship of herpesvirus type 2 to carcinoma of the prostate. A total of 305 patients (224 with benign prostatic hypertrophy and 81 with prostatic carcinoma) who underwent transurethral resection of the prostate was studied. Viral cultures were obtained from urethral swabs and urine preoperatively. Prostatic tissue removed at operation was grown as tissue explants, using a monolayer cell culture technique, and examined by specific immunofluorescence and electron microscopy for evidence of herpesvirus type 2. The sera of the patients also were tested for specific antibody to herpesvirus type 2 by the indirect hemagglutination inhibition test. Although herpesvirus was not isolated 5 per cent of the patients had evidence of herpesvirus type 2 antigen in prostatic tissues by specific immunofluorescence. Electron microscopy failed to reveal the presence of viral particles. There was an increased prevalence of herpesvirus type 2 antibody in patients with carcinoma of the prostate compared to the controls with benign prostatic hypertrophy (p less than 0.05). Although marital status was similar the patients with prostatic cancer tended to marry at an earlier age, have more children, more sexual partners and more exposure to prostitutes than their counterparts with benign prostatic hypertrophy. The demonstration of specific herpesvirus type 2 antibody in patients with prostatic cancer supports an etiologic role for herpesvirus type 2 but further studies are needed to describe more definitively the relationship since the indexes of sexual activity are remarkably high in both groups.

The antiviral effects of humoral antibodies and adenine arabinoside on encephalitis due to Herpesvirus hominis were studied in three-week-old mice. Exogenously administered antibodies to H. hominis, of rabbit or human origin, significantly reduced morbidity and mortality rates from H. hominis encephalitis if enough antibodies were given during the early phase of infection. Adenine arabinoside could also modulate the pathogenesis and reduce the mortality rate in mice with H. hominis encephalitis. Simultaneous administration of adenine arabinoside and human immune globulin resulted in an enhanced protection against H. hominis encephalitis. This increased protection was manifested by a significant reduction of mortality rate, a decrease in concentration of virus, and a lessening of histopathologic damage in the brain tissues. Mechanisms involved in the enhanced protective effects were not well defined. The use of adenine arabinoside plus human immune globulin did not completely suppress viral replication. Therefore, host recovery was probably mediated through (1) partial suppression of viral replication by adenine arabinoside, (2) neutralization of cell-free virus by antibodies, and (3) collaboration of antibodies with other host resistance factors (e.g., complement, leukocytes, nonimmune effector cells, etc.). Our data suggest that control of severe H. hominis infection may require the combined use of an antiviral agent and humoral factor and, perhaps, enhancement of host responses by other means.
