ABSTRACT

Progressive multifocal leukoencephalopathy (PML) is a demyelinating disease of the CNS caused by reactivation of JC virus (JCV) in a setting of cellular immunosuppression. Originally, PML was observed in patients with advanced HIV infection, lymphoproliferative disorders and transplant recipients. However, the widespread use of HIV antiretroviral drugs and the new selective immunomodulatory and immunosuppressive medications, such as Rituximab and Natalizumab, has recently modified the epidemiology, clinical presentation and prognosis of PML. Herein, we discuss the new concepts on PML, emphasizing the recent modification in the epidemiology; the impact of new immunomodulatory treatments in the disease, PML-IRIS (Immune reconstitution inflammatory síndrome), new treatment strategies and other JCV related CNS diseases.


A leucoencefalopatia multifocal progressiva (LMP) é uma doença desmielinizante do sistema nervoso central (SNC) causada pela reativação do vírus JC (JCV) em um ambiente de imunossupressão celular. Originalmente, LMP foi descrita em pacientes com infecção avançada pelo HIV, doenças linfoproliferativas e transplantados. No entanto, a utilização generalizada de anti-retrovirais para a infecção pelo HIV e novos imunomoduladores seletivos e imunossupressores, como Rituximab e Natalizumab, modificaram recentemente a epidemiologia, apresentação clínica e prognóstico da LMP. Neste artigo, vamos discutir os novos conceitos sobre LMP, enfatizando a recente modificação na epidemiologia, o impacto de novos tratamentos imunomoduladores na doença, síndrome inflamatória da reconstituição imune, novas estratégias de tratamento e outras doenças relacionadas ao JCV no SNC.

ABSTRACT

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.


Se presenta el caso clínico de un paciente de sexo masculino, de 43 años portador de VIH que desarrolló un grave daño neurológico subagudo debido a una leucoencefalopatía multifocal progresiva diagnosticada mediante reacción de polimerasa en cadena de virus JC. El paciente fue tratado con terapia anti-retroviral de penetración eficiente al SNC y con mirtazapina, un antidepresivo inhibidor de los receptores de serotonina. Su evolución durante un año de seguimiento ha sido favorable tanto del punto de vista clínico como de imágenes.
