Purpose:
Melioidosis is a potentially fatal infectious disease caused by Burkholderia pseudomallei. Neurologic involvement in pediatric age group is very rare, and only a handful of cases have been reported in literature. We sought to provide a systematic review of pediatric neurologic melioidosis.
Methods:
Literature review was performed to analyze reported cases of pediatric neurologic melioidosis (≤16 years) by searching online database (PubMed/MEDLINE).
Results:
Twenty-seven cases were analyzed. Mean age was 6.7 years (range 2 days-14 years) and around 50% were older children (>5 years). Cranial nerve palsies and fever were most common presenting features. Major manifestations were meningoencephalitis in 16 (59%) and cerebral abscesses in eight (29%) cases. Abscesses were mostly located in parietal lobe. Among older children, abscesses were common than meningeal disease, while being converse for neonates. Mean follow-up duration was 11.5 months. Ten cases showed good to excellent outcome, while eight cases had fair (incomplete recovery) outcomes. The overall mortality rate was 18.5% (5/27) and tends to decrease with age. Among the five deaths, 4 (80%) had septicemia or pneumonia.
Conclusions:
Pediatric neurologic melioidosis is very rare. Meningoencephalitis is the most common presentation. Mortality is the highest in neonates. Ceftazidime appears to be the drug of choice in intensive phase, although the best drug in maintenance phase cannot be commented upon, especially in very young children.
Insights
Pediatric neurologic melioidosis, caused by Burkholderia pseudomallei, is rare. Meningoencephalitis is the most common presentation, with mortality highest in neonates.
Area of Science:
- Infectious Diseases
- Neurology
- Pediatrics
Background:
- Melioidosis is a severe infectious disease caused by Burkholderia pseudomallei.
- Neurologic involvement in children is exceptionally rare, with limited documented cases.
Purpose of the Study:
- To systematically review and analyze reported cases of pediatric neurologic melioidosis.
- To understand the clinical presentation, outcomes, and mortality associated with this rare condition in children.
Main Methods:
- A comprehensive literature review was conducted.
- Cases of pediatric neurologic melioidosis (patients ≤16 years) were identified and analyzed from online databases, primarily PubMed/MEDLINE.
Main Results:
- Twenty-seven pediatric cases were analyzed, with a mean age of 6.7 years.
- Meningoencephalitis (59%) and cerebral abscesses (29%) were the primary neurological manifestations.
- Mortality was 18.5%, highest in neonates, and often associated with septicemia or pneumonia.
Conclusions:
- Pediatric neurologic melioidosis is a rare but serious condition.
- Meningoencephalitis is the most frequent presentation, and mortality is highest in the neonatal age group.
- Ceftazidime is the recommended drug for the intensive phase of treatment.
