[HIV infection and syphilis. Case description and literature review]

Recent case reports emphasize that HIV infection may influence the clinical picture, course and therapy of concurrent syphilis. The case of a 32-year-old patient with coinfection by T. pallidum and HIV is presented. Clinical presentation, diagnostic procedures and therapy are discussed in the light of the current literature. False negative serologic tests for syphilis in HIV-patients raise the question of the sensitivity of these tests in HIV infection. Efficacy of therapy for neurosyphilis and the value of CSF (cerebrospinal fluid) examination in early syphilis are of increased importance in HIV infection. Current guidelines for diagnosis and therapy of syphilis in HIV patients are outlined.
