Un papel importante para los virus en la encefalopatía infantil aguda
Lancet (London, England)
|May 3, 1986
Resumen
La enfermedad neurológica aguda en niños y adultos a menudo es causada por infecciones virales que afectan al sistema nervioso central. La respuesta del huésped, en lugar del virus específico, parece ser el principal impulsor de la gravedad de la enfermedad.
Área de la Ciencia:
- Neurología Neurología.
- Virología Virología.
- Inmunología Inmunología.
Sus antecedentes:
- Las afecciones neurológicas agudas en niños y adultos presentan desafíos diagnósticos.
- Las infecciones virales son una causa sospechosa de deterioro neurológico agudo.
Objetivo del estudio:
- Investigar las causas de la enfermedad neurológica aguda en pacientes pediátricos y adultos.
- Para identificar el papel de las infecciones virales y la respuesta del huésped en la patogénesis de la enfermedad.
Principales métodos:
- Estudio prospectivo de 32 pacientes con depresión aguda de la conciencia o signos neurológicos focales.
- Análisis del suero y el líquido cefalorraquídeo para detectar la presencia de virus (interferón, anticuerpos).
- Distinguir las etiologías infecciosas de las no infecciosas.
Principales resultados:
- Se identificó una causa no infecciosa en 3 pacientes.
- Se encontraron evidencias de infección viral activa en 25 de los 29 pacientes restantes.
- La invasión del sistema nervioso central por virus se confirmó en 11 pacientes, con una investigación temprana que arrojó el mayor éxito de diagnóstico.
Conclusiones:
- Las infecciones virales son una causa importante de enfermedades neurológicas agudas.
- La respuesta inmune del huésped parece ser más crítica que el agente viral específico para determinar la gravedad de la enfermedad.
- Las investigaciones diagnósticas rápidas son cruciales para identificar las etiologías virales.

01:18Viral Meningitis
Viral meningitis is the most common form of meningitis and is often referred to as aseptic meningitis to indicate the absence of bacterial involvement. It is generally milder than bacterial meningitis, with symptoms including fever, headache, stiff neck, drowsiness, nausea, photophobia, and vomiting. Rarely, more severe manifestations or death may occur. Common causative agents include enteroviruses, particularly coxsackie A and B viruses and echoviruses, all members of the Enterovirus genus...
01:17Poliomyelitis
Poliomyelitis is caused by poliovirus, a small, non-enveloped, positive-sense RNA virus of the Picornaviridae family and Enterovirus genus. Transmission occurs primarily via the fecal-oral route, often through ingestion of contaminated water or food. The virus initially replicates in the oropharynx and intestinal mucosa, particularly in lymphoid tissues such as the tonsils, Peyer’s patches, and regional lymph nodes. Primary viremia follows, allowing dissemination throughout the body.In most...
01:25Arboviral Encephalitis
Arboviral encephalitis refers to brain inflammation caused by arthropod-borne viruses, particularly those transmitted through mosquito vectors. Among these, West Nile virus (WNV), a member of the Flaviviridae family, is a significant public health concern. WNV is an enveloped, positive-sense, single-stranded RNA virus. Human infection typically begins when an infected mosquito introduces the virus into the dermis during feeding. The primary transmission cycle involves birds as amplifying hosts...
01:26Bacterial Meningitis II: Pathophysiology
Bacterial meningitis typically begins when pathogens such as Neisseria meningitidis and Streptococcus pneumoniae colonize the nasopharynx and invade the bloodstream. This process is facilitated by bacterial virulence factors, such as polysaccharide capsules, which resist phagocytosis and complement-mediated killing. Less commonly, bacteria reach the central nervous system via contiguous spread from infections like otitis media or sinusitis, through congenital or acquired dural defects, or...
01:19Encephalitis l: Introduction
Encephalitis is inflammation of the brain parenchyma, most often due to infections or autoimmune processes. It presents with neuropsychiatric features such as fever, altered mental status, behavioral changes, cognitive dysfunction, seizures, focal deficits, and sometimes autonomic instability. In some cases, the meninges are also involved, resulting in meningoencephalitis.Infectious CausesInfectious encephalitis is most commonly viral but can also result from bacterial, fungal, or parasitic...
01:26Encephalitis ll: Pathophysiology
Encephalitis is inflammation of the brain parenchyma caused by direct viral invasion or immune-mediated mechanisms triggered by infections or tumors. Both processes lead to neuronal injury, disrupted neurotransmission, and diverse neurological symptoms, often with overlapping clinical and pathological features.Autoimmune EncephalitisIn autoimmune encephalitis, antibodies target neuronal antigens on cell surfaces, synapses, or within neurons. A key example is anti-NMDAR encephalitis, which can...
