[2 men with active syphilis infection and HIV-I infection]

We report the case histories of two men who were living together and who were seropositive for human immune deficiency virus (HIV) and also had positive syphilis tests. Conceivably, reactivation of an earlier syphilis infection (which had been treated) had occurred after infection with HIV. It is therefore recommended to treat such patients according to the standard of treatment of neurosyphilis.
