[Demyelinating cerebral lesions in an immunocompetent HIV-1 patient].

We report the case of a 32-year-old immunocompetent HIV patient, presenting with acute demyelinating leukoencephalopathy. The patient displayed clinical and radiological features similar to multiple sclerosis. Histology revealed inflammation with necrosis, demyelination and destruction of axons. Serum tests were negative for various infectious agents as well as specific cultures and PCR. Corticotherapy and many antibiotic treatments failed. Resorption of the lesions occurred after partial excision and highly-active antiretroviral therapy (HAART). No recurrence was noted. This demyelinating cerebral disease was considered as the primary manifestation of HIV infection. HIV implication in the genesis of the process and its perpetuating this condition was suspected, but the mechanism is unclear. Dysimmune consequences related to the early course of HIV infection could be prevented by antiretroviral treatment. This study was the first description of tritherapy effectiveness on HIV related multiple sclerosis (MS)-like illness.
