La asociación de la infección por el parvovirus B19 humano con la meningoencefalitis aguda aguda
Lancet (London, England)
|September 12, 2001
Resumen
El parvovirus B19 puede causar meningoencefalitis, una inflamación grave del cerebro. Este estudio encontró una incidencia del 4,3% durante un brote, con resultados graves en algunos pacientes, incluida la muerte y problemas neurológicos.
Área de la Ciencia:
- Neurología Neurología.
- Virología Virología.
- Enfermedades infecciosas Enfermedades infecciosas.
Sus antecedentes:
- El parvovirus B19 es un virus común, pero su papel en causar meningoencefalitis no está bien definido.
- La meningoencefalitis es una inflamación del cerebro y las meninges, que se presenta con diversos síntomas neurológicos.
Objetivo del estudio:
- Para determinar la incidencia de la meningoencefalitis por el parvovirus B19.
- Para describir la presentación clínica y los resultados de la meningoencefalitis por parvovirus B19.
Principales métodos:
- Se analizaron muestras de líquido cefalorraquídeo de 162 pacientes con meningoencefalitis no diagnosticada durante un brote.
- La PCR anidada se utilizó para detectar el ADN del parvovirus B19 en el líquido cefalorraquídeo.
Principales resultados:
- La meningoencefalitis por parvovirus B19 fue diagnosticada en 7 pacientes (incidencia del 4,3%) durante el brote.
- Se identificaron cinco casos adicionales de otros años.
- Tres pacientes con trastornos subyacentes (HLH, síndrome de Cockayne, síndrome de Turner) murieron.
- Se produjeron secuelas neurológicas en tres sobrevivientes, correlacionadas con anomalías de escáner cerebral en fase aguda.
Conclusiones:
- El parvovirus B19 es una causa significativa de meningoencefalitis, particularmente durante los brotes.
- Los pacientes con enfermedades subyacentes enfrentan un mayor riesgo de mortalidad.
- Las secuelas neurológicas son una preocupación en los sobrevivientes, lo que pone de relieve la importancia del diagnóstico y el seguimiento tempranos.

01:24Bacterial Meningitis
Bacterial meningitis is a severe infectious disease involving inflammation of the meninges, the protective membranes surrounding the brain and spinal cord. It occurs when pathogenic bacteria cross the blood–brain barrier and enter the cerebrospinal fluid. Common causative organisms include Neisseria meningitidis, Streptococcus pneumoniae, Haemophilus influenzae type b, Listeria monocytogenes, and Escherichia coli K1. The exact route of entry varies by pathogen and host condition.Routes of Entry...
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...
01:25Arboviral 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...
01:22Bacterial Meningitis I: Introduction
Bacterial meningitis is a severe, life-threatening inflammation of the meninges, particularly the pia mater and arachnoid mater, affecting the subarachnoid space, ventricles, and cerebrospinal fluid (CSF). If untreated, it can lead to significant neurological complications or death.Causative AgentsCommon pathogens vary with age and immune status. In adults, major organisms include Streptococcus pneumoniae, Neisseria meningitidis, and Haemophilus influenzae. Streptococcus agalactiae (group B...
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...
