[Ocular syphilis associated to HIV: A report of 2 patients treated in Marrakech, Morocco]

Syphilis is a sexually transmitted disease. All organs might be affected, but ocular syphilis occurs only in 0.6 percent of patients. A resurgence of syphilis cases has been observed for several years in many countries, especially in HIV-infected subjects. These patients often present with concomitant primary and secondary lesions or extensive presentations of syphilis.

We report 2 patients with syphilitic uveitis diagnosed and treated at the department of infectious diseases at the University hospital of Marrakech. Ocular involvement was inaugural in both HIV patients. Each had a specific treatment, but none had a complete recovery of visual function; the first patient was treated by ceftriaxone and the second one was treated by penicillin.

Syphilis must be discussed in all patients diagnosed with uveitis or papillitis. The diagnosis should be suspected in cases of eye inflammation even in the absence of favourable clinical presentation or anamnesis. Search for HIV co-infection should be systematic. Although not evidence-based, prompt therapy may lead to functional recovery. Ceftriaxone could be a suitable alternative to penicillin in the treatment of early syphilis in HIV-infected patients. This treatment has a concomitant effectiveness even for asymptomatic forms of neurosyphilis. Ocular syphilis is a form of neurosyphilis and requires neurosyphilis therapy regardless of when it develops after primary infection.Conventional syphilis staging is of little use in understanding ocular syphilis. Co-infection between HIV and ocular syphilis is common, but does not affect response to a neurosyphilis regimen of penicillin in the short term.
