Purpose: Rotaviruses, noroviruses, astroviruses, and enteric adenoviruses cause acute gastroenteritis (AGE) in children. Some children with AGE have afebrile convulsions associated with viral gastroenteritis. The purpose of this study was to detect and genotype viruses from children with AGE or benign infantile seizures associated with mild gastroenteritis (BIS-MG).
Methods: Between August 2004 and June 2005, 311 children with AGE were included. Four viral agents, including rotavirus, norovirus, astrovirus, and adenovirus, were analyzed from stool specimens of each patient using the latex agglutination method, enzyme immunoassay, and reverse transcriptase polymerase chain reaction. Genotyping of each virus was performed in 217 of the 311 children.
Results: Among 217 children (male, 121; female, 96; mean age, 20.6±15.4 months), rotavirus was detected in 109 (50.2%), norovirus in 28 (12.9%), adenovirus in 13 (6.0%), and astrovirus in 2 children (0.9%). Genotyping of rotavirus revealed positive results in 97 children; P[8]G3 in 36, P[4]G2 in 21, P[6]G4 in 10, P[4]G4 in 9, P[8]G9 in 6, P[8]G1 in 6, P[4]G3 in 4, P[4]G9 in 3, and P[6]G2 in 2. Genotyping of norovirus showed GII-4 in 27 of 28 children and GII-6 in 1 child. Sixteen children were diagnosed with BIS-MG. Rotavirus was detected in 13 of 16 children with BIS-MG, and norovirus in 2 children. Genotyping of rotavirus detected in children with BIS-MG revealed P[8]G3 in 6 children, P[4]G2 in 2 children, and P[4]G9 in 1 child.
Conclusion: Analysis of viruses from stool specimens indicates that both rotavirus and norovirus are the main viruses related to BIS-MG in children.
