Insights
Cystic fibrosis can cause facial palsy in infants due to vitamin A deficiency. Supplementation and standard cystic fibrosis care improved the infant's facial nerve function.
Area of Science:
- Pediatric Neurology
- Pulmonology
- Clinical Nutrition
Background:
- Facial palsy in infants can be idiopathic, necessitating thorough investigation.
- Cystic fibrosis (CF) is a genetic disorder affecting multiple organ systems.
- Hypovitaminosis A is a known complication in malabsorptive conditions like CF.
Observation:
- A 15-week-old male infant presented with bilateral lower motor neuron facial palsy.
- The infant experienced growth deterioration, worsening cough, and wheeze.
- Diagnosis of cystic fibrosis was confirmed, with co-existing hypovitaminosis A.
Findings:
- Standard cystic fibrosis management, including vitamin A supplementation, was initiated.
- The infant showed improvement in bilateral lower motor neuron facial palsy.
- This suggests a potential link between hypovitaminosis A and facial nerve dysfunction in CF.
Implications:
- Highlights the importance of screening for vitamin A deficiency in infants with CF.
- Suggests vitamin A repletion as a therapeutic strategy for certain neurological manifestations in CF.
- Underscores the multifaceted impact of cystic fibrosis on infant development and neurological function.
Abstract:
A 15-week old male infant presented with bilateral lower motor neuron facial palsy of unknown cause. Subsequently his growth deteriorated and he developed progressively worsening cough and wheeze. A diagnosis of cystic fibrosis was confirmed and hypovitaminosis A detected. Improvement of the facial palsy was noted following standard management of cystic fibrosis including vitamin A supplementation.

CF is primarily caused by a genetic mutation in a chromosome 7 gene coding for the cystic fibrosis transmembrane conductance regulator (CFTR) protein. The most common gene mutation leading to CF is the ΔF508 mutation, but...
