title: [Immunogenicity of synthetic sex hormones and thrombogenesis].
abstract: The ingestion of synthetic steroidal and non-steroidal estrogens may induce antiestrogen antibodies in women on oral contraceptives, and in prostatic patients treated with diethylstilbestrol (DES). Natural sex hormones have no such effect. A radioimmunoassay with tritiated ethinylestradiol or DES was applied to study the prevalence of synthetic sex hormone antibodies in 2 populations: 100 women on estroprogestative hormones and 93 cases of DES treated prostatic cancers. Homologous non-treated controls were compared. Results allowed to identify among treated and asymptomatic subjects an immunoreactive population of 30% women and 47% men. Furthermore, the antibodies were found with a much higher frequency (p less than 0.001) in patients who had experienced a thromboembolic disease while on treatment: 90% of women and 74% of men. The importance of these antibodies as a risk factor, their possible role in promoting vascular lesions, the interest of their detection for the prevention of the vascular risk induced by synthetic sex hormones, are considered.
