[Serological cardiolipid development of early syphilis treated with a single injection of benzathine-penicillin of 2,400,000 I.U].

For one year, the authors have observed the clinical and biological development of early syphilis on 205 patients infected between 1971 and 1979 and treated by a single injection of Benzathine-Penicilline of 2,400,000 U.I. The serological negativeness has been obtained in the proportions as follow: - 91,43 p. 100 of primary syphilis (blood test positive), - 88,57 p. 100 of secondary syphilis, - 67,69 p. 100 of latent syphilis. These results compared to those obtained by other more time-consuming and expensive methods, can be considered as satisfactory.
