[Antibodies against Cytomegalovirus and Herpes simplex virus in alcoholics and drug addicts].

Anti-CMV and anti-HSV type 1 of the IgG class were tested in 123 consecutive outpatient alcoholics and 95 consecutive drug addicts admitted to a detoxification ward. The prevalence of both viral markers in these groups was not different from the prevalence found among controls, however, antibody titres were significantly higher. Only weak correlation was found between titres of anti-CMV and anti-HSV in tested subjects. The reasons responsible for high titres of anti-CMV and anti-HSV remain to be determined.
