[Mirtazapine and antiretroviral therapy in the treatment of progressive multifocal leukoencephalopathy associated with HIV-1 infection: report of a case and review of literature].

We report a 43 years old HIV-1 infected male who developed a severe subacute neurological damage because of a progressive multifocal leukoencephalopathy confirmed by PCR for JC virus. The patient was treated with antiretroviral therapy in adequate doses for CNS penetration and mirtazapine, an antidepressant inhibitor of serotonin receptors. His evolution during one year follow up has been favorable in both, clinically and images.
