ABSTRACT
OBJECTIVES: This study was undertaken to characterize the neuroinfection profile in a tertiary neurological ward. INTRODUCTION: Neuroinfection is a worldwide concern and bacterial meningitis, tetanus and cerebral malaria have been reported as the commonest causes in developing countries. METHODS: From 1999 to 2007, all patients admitted to the Neurology Ward of Hospital das Clínicas, São Paulo University School of Medicine because of neuroinfection had their medical records reviewed. Age, gender, immunological status, neurological syndrome at presentation, infectious agent and clinical outcome were recorded. RESULTS: Three hundred and seventy four cases of neuroinfectious diseases accounted for 4.2 percent of ward admissions and the identification of infectious agent was successful in 81 percent of cases. Mean age was 40.5 + 13.4 years, 63.8 percent were male, 19.7 percent were immunocompromised patients and meningoencephalitis was the most common clinical presentation despite infectious agent. Viruses and bacteria were equally responsible for 29.4 percent of neuroinfectious diseases; parasitic, fungal and prion infections accounted for 28 percent, 9.6 percent and 3.5 percent respectively. Human immunodeficiency virus (HIV), herpes simplex virus 1 (HSV1), Mycobacterium tuberculosis, Treponema pallidum, Taenia solium, Schistosoma mansoni, Cryptococcus neoformans and Histoplasma capsulatum were the more common infectious pathogens in the patients. Infection mortality rate was 14.2 percent, of which 62.3 percent occurred in immunocompetent patients. CONCLUSION: Our institution appeared to share some results with developed and developing countries. Comparison with literature may be considered as quality control to health assistance.

O comprometimento do sistema nervoso periférico é frequente nas vasculites sistêmicas e contribui decisivamente para o diagnóstico. Oito pacientes foram estudados: sete do sexo feminino e um do sexo masculino; cinco brancos, dois negros, um amarelo; média de idade de 55,9 anos; quatro com poliarterite nodosa, um com lúpus eritematoso sistêmico, um com artrite reumatóide, um com vasculite isolada do sistema nervoso periférico e um com vasculite livedóide. Todos foram submetidos a terapêutica intravenosa com pulsos mensais de metilprednisolona (1 g/dia/3dias) e ciclofosfamida (1 g/dia). Cinco pacientes melhoraram, dois permaneceram inalterados e um faleceu. A melhora neurológica objetiva ocorreu após o terceiro ou quarto pulso e nos pacientes com menor duraçao da doença.
