Factors Associated with Respiratory Insufficiency in Children with Guillain-Barré Syndrome

Area of Science:

• Pediatric Neurology
• Neuromuscular Disorders
• Critical Care Medicine

Background:

• Guillain-Barré syndrome (GBS) is a rare autoimmune disorder affecting the peripheral nervous system.
• Respiratory insufficiency is a serious complication of GBS in children, but its risk factors are not well understood.

Purpose of the Study:

• To identify clinical and demographic factors associated with respiratory insufficiency in pediatric patients diagnosed with GBS.
• To establish potential prognostic markers for respiratory compromise in children with GBS.

Main Methods:

• A retrospective study analyzed data from 103 children diagnosed with GBS between January 2013 and October 2022.
• Patients were categorized into groups based on the need for assisted breathing during treatment.
• Statistical analysis compared characteristics between groups, including weakness patterns, functional grading, and time intervals.

Main Results:

• Children experiencing respiratory insufficiency were more likely to present with facial and/or bulbar weakness (p=0.002) and had higher Hughes Functional Grading Scale (HFGS) scores at admission (p<0.001).
• A shorter interval from symptom onset to hospital admission was also significantly associated with respiratory insufficiency (p=0.017).
• While subtypes like AIDP and AMAN showed different clinical features, the incidence of respiratory insufficiency did not differ significantly between them.

Conclusions:

• Facial/bulbar weakness, admission HFGS score, and onset-to-admission interval are significant predictors of respiratory insufficiency in pediatric GBS.
• These identified factors may serve as valuable prognostic markers for anticipating and managing respiratory complications in children with GBS.
