Polyradiculoneuritis in children groups during simultaneous circulation of enteroviruses and adenoviruses
Insights
Two pediatric cases of polyradiculoneuritis were linked to concurrent viral infections. Respiratory infections preceded paralysis, with coxsackievirus and adenovirus co-circulation potentially compromising immunity.
Area of Science:
- Virology
- Pediatric Neurology
- Infectious Diseases
Background:
- Polyradiculoneuritis, a rare neurological disorder, affects children.
- Investigating the etiology of paralytic diseases in pediatric populations is crucial.
Observation:
- Two pediatric cases of polyradiculoneuritis occurred in 1984.
- Both cases were preceded by respiratory infections in the affected children.
- Children were from a newly formed group in a medical institution and a long-standing nursery school.
Findings:
- Coxsackievirus A9 was isolated from the first patient.
- Adenovirus types 3 and 29 were concurrently identified with Coxsackievirus A9 in the second patient.
- Serological and isolation studies confirmed the co-circulation of enteroviruses and adenoviruses among contacts in both settings.
Implications:
- Concurrent circulation of adenoviruses and enteroviruses may play a role in the pathogenesis of polyradiculoneuritis.
- This suggests a potential link between mixed viral infections and compromised immunity leading to paralysis in children.
- Further research into viral interactions and their impact on the immune system is warranted.
Abstract:
Two cases of polyradiculoneuritis in children were noted during January, 1984. Each girl was a member of a different group of children: the first group was newly constituted of children from various remote regions of Czechoslovakia in a Medical Institution, the second one included children attending the same nursery school for a long time. In both groups, all or most of the children went through one or two respiratory infections which preceded the development of a paralytic disease. From the first girl, coxsackievirus A9 was recovered in nasopharyngeal swabs and in a stool sample. Among contacts in the Children's Medical Institution, a concurrent circulation of this enterovirus and of an adenovirus type 3 was demonstrated by isolation attempts and confirmed by serological examinations. From the second girl, coxsackie A9 and an adenovirus type 29 were demonstrated in the same stool sample and a simultaneous circulation of both virus species among the nursery school and family contacts was proved by isolation attempts and by serological investigations. The concurrent, overlapping or sequential circulation of adenoviruses and enteroviruses may perhaps contribute to a compromised immunity resulting in a manifestation of paralysis.
