An infant with chronic, relapsing polyneuropathy responsive to steroids
Developmental Medicine and Child Neurology
|August 1, 1982
Insights
A rare chronic inflammatory polyneuropathy was diagnosed in an infant. This steroid-responsive condition caused relapsing paralysis, highlighting its early-onset potential.
Area of Science:
- Neurology
- Pediatrics
- Immunology
Background:
- Acute flaccid paraparesis in infants is a critical diagnostic challenge.
- Chronic inflammatory demyelinating polyneuropathy (CIDP) is typically diagnosed in adults.
- Early-onset neuropathies require thorough investigation due to potential for severe morbidity.
Observation:
- A seven-week-old infant presented with acute flaccid paraparesis.
- The infant experienced recurrent episodes of weakness and neurological decline.
- Minor illnesses triggered exacerbations, while corticosteroid therapy induced remissions.
Findings:
- Postmortem examination confirmed a chronic inflammatory polyradiculopathy.
- This case represents the youngest documented patient with this condition.
- The polyneuropathy demonstrated a relapsing-remitting course responsive to steroids.
Implications:
- This case expands the known age spectrum for chronic, relapsing, steroid-responsive polyneuropathies.
- Early diagnosis and management of pediatric polyneuropathies are crucial.
- Further research into the pathogenesis and treatment of early-onset inflammatory neuropathies is warranted.
Abstract:
A seven-week-old infant presented with an acute flaccid paraparesis. Her subsequent course was punctuated by numerous exacerbations, in association with minor intercurrent illness and remissions produced by corticosteroid treatment. Postmortem examination revealed a chronic inflammatory polyradiculopathy. She represents the youngest patient yet described with a chronic, relapsing, steroid-responsive polyneuropathy.
