Abstract
Summary
A 7.7% incidence of antibodies directed against Gm (a), Gm (b) and Gm (f) antigens of IgG was noted in 298 adolescent drug addicts, as compared to 0.9% in a nonaddicted control group. Isoimmunization as a stimulus for Gm antibody production in addicts was indirectly excluded. A significant association between anti-Au and anti-Gm in the sera of drug addicts was found, which suggests that the hepatitis agent associated with Australia antigen may be responsible for the induction of Gm antibodies in this group.
