This study on acute viral encephalitis found a 28% mortality rate and identified rapid deterioration and patient age as key predictors of poor outcomes in viral encephalitis cases.

Area of Science:

  • Neurology
  • Virology
  • Infectious Diseases

Background:

  • Acute viral encephalitis is a serious neurological condition.
  • Understanding its causes and outcomes is crucial for patient management.

Purpose of the Study:

  • To investigate the viral etiology and clinical outcomes of acute viral encephalitis.
  • To identify predictors of unfavorable outcomes in affected patients.

Main Methods:

  • Retrospective study of 57 patients diagnosed with acute viral encephalitis.
  • Classification into presumed (48 cases) and post-infectious (9 cases) groups.
  • Viral isolation and analysis of clinical data, including neurological sequelae and mortality.

Main Results:

  • A viral etiology was identified in 26% of cases, with influenza, Coxsackie, adenovirus, CMV, and HSV isolated.
  • The overall mortality rate was 28%.
  • Among survivors, 76% had normal outcomes, while 24% experienced neurological sequelae, including deficits, personality changes, intellectual disability, hyperactivity, and epilepsy.

    • Conclusions:

    • Rapid deterioration of consciousness level post-admission and patient age are significant predictors of poor outcomes in acute viral encephalitis.
    • Prompt diagnosis and management are essential to mitigate neurological sequelae and reduce mortality.
