ABSTRACT

Varicella-zoster virus (VZV) meningoencephalomyelitis is a rare but severe neurological complication of VZV reactivation in immunocompromised patients. We report the case of an HIV-infected individual who developed an acute and severe meningoencephalomyelitis accompanied by a disseminated cutaneous eruption due to VZV. The presence of VZV DNA in cerebrospinal fluid was confirmed by polymerase chain reaction (PCR) technique. The patient started undergoing an intravenous acyclovir therapy with a mild recovery of neurological manifestations. Varicella-zoster virus should be included as a cause of acute meningoencephalomyelitis in patients with AIDS. Early diagnosis followed by specific therapy should modify the rapid and fulminant course for this kind of patients.


A meningoencefalomielite pelo vírus varicela-zoster (VVZ) é uma complicação neurológica rara mas grave da reativação do VVZ em pacientes imunocomprometidos. Nós relatamos o caso de um indivíduo infectado por HIV que desenvolveu uma meningoencefalomielite aguda e grave acompanhada por uma erupção cutânea por causa do VVZ. A presença do DNA do VVZ no líquor foi confirmada pela técnica de reação em cadeia da polimerase (PCR). O paciente iniciou uma terapia intravenosa com aciclovir com uma leve recuperação das manifestações neurológicas. O vírus varicela-zoster deve ser incluído como uma causa de meningoencefalomielite nos pacientes com AIDS. O diagnóstico precoce seguido por terapia específica pode modificar o curso rápido e fulminante deste tipo de pacientes.

ABSTRACT

The reactivation of human herpesvirus 6 (HHV-6) in patients with AIDS can result in an acute and severe diffuse meningoencephalitis. We describe the epidemiological, clinical and outcome findings of five patients with diagnosis of HIV/AIDS and central nervous system involvement (CNS) due to HHV-6. Fever was present in all the patients. Meningeal compromise, seizures and encephalitis were present in some of the patients. Polymerase chain reaction (PCR) of cerebrospinal fluid (CSF) specimens was positive for HHV-6 in all the patients. HHV-6 should be included among opportunistic and emerging pathogens that involve the CNS in patients with AIDS.


A reativação do herpesvírus humano 6 (HHV-6), em um hospedeiro com AIDS, pode resultar em meningoencefalite aguda difusa. Nós descrevemos a epidemiologia, a clínica e resultados encontrados em cinco pacientes com diagnóstico de HIV/AIDS e comprometimento do sistema nervoso central (SNC) devido ao HHV-6. Todos os pacientes apresentaram febre. Sinais e sintomas de comprometimento meníngeo, convulsões e encefalite podem ser encontrados. A reação em cadeia da polimerase (PCR) de amostras do líquor foi positiva para HHV-6 em todos os pacientes. O HHV-6 deve ser incluído entre os patógenos emergentes oportunistas que comprometem o SNC de pacientes com AIDS.
