Coxsackievirus B1 infection in infants less than 2 months of age

Am J Perinatol. 1998 Mar;15(3):155-9. doi: 10.1055/s-2007-993917.


Most of the neonatal enteroviral infections reported in the literature are associated with Coxsackievirus B2-B5 and echovirus 9 and 11. We report a retrospective Coxsackievirus B1 (CB1) infection in infants less than 2 months of age. Seventeen patients had aseptic meningitis and 8 had systemic sepsis (multi-organ involvement including meningitis, impaired liver function, and abnormality in coagulation). The symptoms and signs were nonspecific and could not be distinguished with bacterial infection on clinical grounds. Virus isolation was mandatory for diagnosis. Impaired liver function and coagulation profiles were noted in patients with systemic sepsis, but not in patients with meningitis only. CSF examination showed some uncommon features of viral meningitis: predominance of polymorphonuclear cells (PMN) was noted in 62.5% of patients and hypoglycorrhachia in 64% of patients. The patients with only meningitis recovered completely without any sequela. One of the eight patients with systemic sepsis died with case fatality rate 12.5%. Physicians should be aware of the possibility of CB1 virus infection in young infants during prevalent seasons. Specimens should be sent for viral culture in patients with meningitis and sepsis to make a definite diagnosis.
