Objective: After a decade of constant decline, the number of syphilis cases has been steadily increasing since the 2000s, particularly in HIV infected patients. Neurosyphilis is a rare manifestation of this sexually transmitted disease for which we performed a retrospective study and analyzed clinical manifestations., Patients and Methods: We reviewed retrospectively all the neurosyphilis cases admitted to Strasbourg University Hospital between 2004 and 2014. We included and analyzed 13 patients admitted during this period who met the diagnostic criteria for neurosyphilis., Results: Nine of 13 patients had isolated visual manifestations; three (23.1%) experienced posterior uveitis, two (15.4%), panuveitis, and 4 (30.8%) had papillitis. Out of five patients (38.5%) who were HIV positive, three (60%) had a CD4 cell count above 400/mm 3 at the time of diagnosis of neurosyphilis. All patients received parenteral penicillin G or cephalosporin, and 5/13 (38.5%) received systemic corticotherapy., Conclusion: Ophthalmologists appear as key players in the identification, management and follow-up of neurosyphilis, since ocular findings are key diagnostic features in these patients., (Copyright © 2017 Elsevier Masson SAS.

Introduction: We report the magnetic resonance imaging (MRI) findings in a case of neurosyphilis revealed by the involvement of two cranial nerves., Case Report: A 41-year-old man developed a right cochleovestibular and left trigeminal neuropathy, associated with high serum titers of VDRL and TPHA, high titers of TPHA in the cerebrospinal fluid (CSF) and several CSF oligoclonal IgG bands. On MRI, hypertrophy and gadolinium contrast enhancement of these cranial nerves were associated with several supratentorial cortical nodules surrounded by marked cerebral edema, corresponding to syphilitic gummas. One of these cortical nodules was biopsied. Microscopic examination showed lesions of meningoencephalitis with necrosis and granulomatous vasculitis. After penicillin therapy, the serum VDRL titers and the MRI abnormalities disappeared, a partial clinical recovery was observed and a significant reduction of the serum TPHA titers was found., Discussion: Such MRI abnormalities are not specific and can be observed in various tumoral, auto-immune and infectious diseases. They can also mimic neurofibromatosis type II. Cranial nerve involvements in neurosyphilis can result from nerve inflammation in basal meningitis, nerve ischemia in meningovasculitis or from compression by an adjacent gumma. In our case, the cranial neuropathy was related to a mixed meningovascular and parenchymatous form of neurosyphilis.

Central nervous system complications are common in HIV-1 infected patients and occur either as a result of concomitant immunosuppression (opportunistic infections, lymphoma and tumors), as a primary manifestation of HIV infection, or as an adverse effect of therapy (immune restoration and toxicity). These complications contribute largely to patient morbidity and mortality. In the era of highly active antiretroviral therapy (HAART) these disease states have changed in presentation, outcome and incidence. We review in detail the epidemiology, pathogenesis, clinical features, diagnosis, and management of these disorders.

Ocular syphilis is rare in human immunodeficiency virus infected individuals. We think that syphilis should be considered in evaluating such patients presenting with uveitis. Most often, ocular syphilis includes retinitis associated with anterior or posterior uveitis, sometimes with optic neuritis. Concurrent neurosyphilis is frequent and may be more aggressive; it may progress more rapidly and cause more atypical signs than in patients without human immunodeficiency virus infection. This suggests the need for lumbar puncture in the evaluation of coinfected patients. The standard serological tests for syphilis (in blood and cerebrospinal fluid) may be nonreactive in human immunodeficiency virus seropositive patients. It may be because of the alteration of immunologic response of such patients. All coinfected patients with human immunodeficiency virus and syphilis should be treated with high-dose intravenous penicillin G sodium as recommended for neurosyphilis. We describe two human immunodeficiency virus infected patients with ocular syphilis and neurosyphilis.
