Acute encephalitis in Swiss children: aetiology and outcome
1Medizinische Universitäts-Kinderklinik Bern, Switzerland.
Insights
This study on pediatric encephalitis and cerebellar ataxia in Switzerland found that 36% of encephalitis patients had sequelae, with young age and seizures indicating a poor prognosis. Acute cerebellar ataxia had a better outcome with fewer long-term effects.
Area of Science:
- Pediatric Neurology
- Infectious Diseases
- Neuroscience
Background:
- Limited data exists on the long-term course and prognosis of pediatric encephalitis and acute cerebellar ataxia in Central Europe.
- Retrospective analysis is crucial for understanding disease progression and outcomes in pediatric neurological conditions.
Purpose of the Study:
- To evaluate the clinical course and prognosis of children diagnosed with acute encephalitis or acute cerebellar ataxia.
- To identify factors associated with poor outcomes in pediatric encephalitis and cerebellar ataxia.
Main Methods:
- Retrospective evaluation of 104 pediatric patients (80 encephalitis, 24 ataxia) treated between 1980-1991.
- Analysis of patient outcomes, including mortality, sequelae (severity), and associated clinical factors.
- Comparison of cerebrospinal fluid findings between patients with and without sequelae.
Main Results:
- 5% of encephalitis patients died acutely; 36% of those followed up developed sequelae (severe, moderate, or mild).
- Young age and seizures were significant predictors of poor outcomes in encephalitis.
- Acute cerebellar ataxia patients had no fatalities and fewer severe sequelae, though some developed mild to moderate residual effects.
- Higher cerebrospinal fluid white cell counts correlated with sequelae in acute cerebellar ataxia patients.
Conclusions:
- Pediatric encephalitis carries a significant risk of mortality and long-term sequelae, influenced by age and seizure activity.
- Acute cerebellar ataxia generally has a favorable prognosis with minimal severe long-term complications.
- Cerebrospinal fluid analysis may aid in predicting sequelae in acute cerebellar ataxia.
Abstract:
Since published data on the course and prognosis of encephalitis in Central Europe is limited, we retrospectively evaluated 104 children with either acute strict sense encephalitis (n = 80) or acute cerebellar ataxia (n = 24) treated at the Department of Pediatrics, University of Bern, Switzerland, between 1980 and 1991. Of the 80 patients with strict sense encephalitis, four (5%) died acutely and 28 (36%) of 78 followed up had sequelae - eight patients with severe, six with moderate and 14 with mild sequelae. Young age and seizures were shown to correlate with poor outcome. Among the 24 patients with acute cerebellar ataxia, there was no fatal outcome and none developed severe residua, but six had mild and one had moderate sequelae. Initial cerebrospinal fluid white cell count was significantly higher in these children with sequelae compared with those without any sequelae after acute cerebellar ataxia.
