From the * Department of Pediatrics and Objective. Sin Nombre hantavirus
(SNV) is the leading causative agent of hantavirus cardiopulmonary
syndrome (HCPS) in the United States and Canada. Relatively few cases
of HCPS have involved children. This report describes the clinical
characteristics of a series of pediatric cases of SNV infection in the
United States and Canada from 1993 through March 2000.
Methods. We analyzed clinical and laboratory data on 13 patients who were Results. The patients ranged from 10 to 16 years of age,
with a median of 14. Fifty-four percent were female. Fifty-four percent
were Native American. The most common prodromal symptoms were fever, headache, and cough or dyspnea (100%); nausea or vomiting (90%); and
myalgia (80%). The most common physical findings at admission were
tachypnea (67%) and fever (56%); hypotension was seen in 33% of
patients. On admission, all patients manifested thrombocytopenia (median platelet count: 67 000/mm3) and elevated lactate
dehydrogenase (median level: 1243 IU/L), and >85% of patients had
elevated levels of serum aspartate aminotransferase, alanine
aminotransferase, and hypoalbuminemia. Leukocytosis and hemoconcentration were seen in less than one third of patients at
admission. HCPS developed in 12 of the 13 patients (92%), and 4 of
those 12 died (33% case-fatality ratio). The majority of HCPS patients
(8 of 12 [67%]) were critically ill and required mechanical
ventilation. Extracorporeal membrane oxygenation was used in 2 patients, 1 of whom survived. An elevated prothrombin time ( Conclusions. Infection with SNV in children and
adolescents causes HCPS with a clinical course and mortality rate
similar to that described in adults. We believe that early recognition
of HCPS in children and adolescents and appropriate referral to
tertiary care centers that are experienced with HCPS are important in
reducing mortality.
