Insights
Bickerstaff
Area of Science:
- Neurology
- Pediatrics
- Immunology
Background:
- Bickerstaff's brainstem encephalitis (BBE) is a rare neurological disorder.
- It often follows an upper respiratory tract infection and is underdiagnosed in children.
Observation:
- Three pediatric patients presented with acute onset of lower limb weakness after initial recovery from infection.
- Symptoms progressed to cranial nerve involvement, consciousness impairment, and coma in one case.
Findings:
- Intravenous immunoglobulin (IVIG) treatment led to rapid and progressive clinical improvement in all three children.
- BBE shares neuro-immune pathogenesis with Fisher syndrome and Guillain-Barré syndrome, suggesting a spectrum of disease.
Implications:
- Early diagnosis and prompt IVIG treatment are crucial for favorable outcomes in pediatric BBE.
- Understanding BBE as part of a broader neuro-immune spectrum can improve diagnostic and therapeutic approaches.
Abstract:
Three young patients with Bickerstaff's brainstem encephalitis (BBE) are reported. Some weeks following an upper tract infection, the children after a short period of recovery, showed acute onset of symmetric weakness of the lower limbs with difficulty in standing by and walking. The distal muscle weakness had a rapid progression with involvement of the cranial nerve, and then with severe impairment of the consciousness till to coma in one of the three children. BBE is a rare and often underdiagnosed affection in childhood. Common neuro-immune pathogenesis, overlap of clinical signs and strict correlation among BBE with Fisher syndrome and Guillain-Barrè syndrome lead to think that these affections represent an unique spectrum with different central and peripheral involvement. In these children, treatment with intravenous immunoglobulins resulted in a progressive and rapid resolution of the clinical features.
