BACKGROUND An increase of syphilis cases has been recorded in the past few decades, especially among HIV-infected patients. These patients often present with concomitant primary and secondary lesions or extensive presentations of syphilis. OBJECTIVE Our goal was to compare alternative regimens to the recommended penicillin treatment. METHODS We retrospectively studied 116 patient files (80% HIV1-infected) treated for a first episode of early syphilis. RESULTS Patients mainly presented with symptoms of secondary syphilis. In 15.5% of the cases patients were asymptomatic and 17.2% of patients with secondary syphilis presented with neurologic or ophthalmic symptoms. Some less usual clinical presentations included diffuse polyadenopathy or isolated fever. The time to serological response was similar among those treated with benzathine-penicillin (n=52), ceftriaxone (n=49), or doxycycline (n=15). CONCLUSIONS Ceftriaxone and doxycycline could be suitable alternatives to penicillin in the treatment of early syphilis in HIV-infected patients. These two treatments have a concomitant effectiveness even for asymptomatic forms of neurosyphilis.

D009494 Neurosyphilis Infections of the central nervous system caused by TREPONEMA PALLIDUM which present with a variety of clinical syndromes. The initial phase of infection usually causes a mild or asymptomatic meningeal reaction. The meningovascular form may present acutely as BRAIN INFARCTION. The infection may also remain subclinical for several years. Late syndromes include general paresis; TABES DORSALIS; meningeal syphilis; syphilitic OPTIC ATROPHY; and spinal syphilis. General paresis is characterized by progressive DEMENTIA; DYSARTHRIA; TREMOR; MYOCLONUS; SEIZURES; and Argyll-Robertson pupils.
