[Baby with respiratory problems and cardiac arrest]

Area of Science:

• Pediatric Neurology
• Critical Care Medicine
• Immunology

Background:

• Acute inflammatory demyelinating polyneuropathy (AIDP) is a rare autoimmune disorder affecting the peripheral nervous system.
• Early diagnosis and treatment are crucial for favorable outcomes in pediatric cases.

Observation:

• A 10-month-old infant presented with respiratory, gastrointestinal, and neurological symptoms, including inspiratory stridor, facial palsy, and ventricular fibrillation.
• Neurophysiological studies revealed prolonged F-responses, and cerebrospinal fluid analysis showed albuminocytologic dissociation, indicative of AIDP.
• Initial suspicion of botulism was ruled out by comprehensive testing.

Findings:

• The infant's presentation mimicked infectious etiologies but was ultimately diagnosed as AIDP.
• Intravenous immunoglobulin (IVIg) therapy resulted in rapid clinical improvement.
• Complete recovery was achieved within six months of treatment.

Implications:

• This case underscores the importance of considering AIDP in infants presenting with severe neurological and cardiac compromise.
• Early recognition and aggressive immunotherapy, such as IVIg, can significantly alter the prognosis for pediatric AIDP.
• Highlights the diagnostic challenges and successful management of a rare pediatric neurological emergency.
