Abstract

The exposure to DNA reactive carcinogens is known to elicit a specific humoral immunological response, with the production of antibodies toward the carcinogen adducts. Consequently, the presence of circulating anti-carcinogen antibodies has been proposed as a marker of carcinogen exposure, and as a potential modulating factor in chemical carcinogenesis. In this work, the presence of serum antibodies to 7β,8α-dihydroxy-9α10α-epoxy-7,8,9,10- tetrahydrobenzo[a]pyrene-DNA (BPDE-DNA) adducts was determined in two groups of workers occupationally exposed to low doses of polycyclic aromatic hydrocarbons (PAHs), i.e. policemen (194 subjects) and workers in the aluminum industry (105 subjects). Specific anti BPDE-DNA antibodies were detected in 5.7% (11/194) of policemen and 13.3% (14/105) of aluminium industry workers. Among policemen, a small, not significant (p=0.09), prevalence of positives was observed in traffic wardens compared to office workers. A borderline significant (p=0.052) prevalence of positives was also observed in heavy smokers compared to light smokers among aluminium industry workers. These results basically support previous findings on the association between chronic exposure to polycyclic aromatic hydrocarbons and formation of anti- BPDE-DNA antibodies, even though such association appears to be weak, possibly biased by individual factors which are still largely unidentified.
