Abstract
BACKGROUND: Acute gastroenteritis (AGE) is a leading cause of pediatric morbidity and mortality. However, the AGE burden from human adenoviruses (HAdV) is not fully defined.
OBJECTIVE: To determine the prevalence and characteristics associated with HAdV in U.S. children.
STUDY DESIGN: We enrolled AGE case-patients < 18 years of age in inpatient and emergency department (ED) settings and healthy controls < 11 years of age between December 2016 and November 2019 at seven pediatric medical centers. Demographic and clinical data and stools were prospectively collected. Stools were tested for HAdV F40/41 using multiplex molecular panels. A subset of 120 HAdV-positive samples was genotyped.
RESULTS: HAdV was detected in 168 (8 %) of 2229 ED patients, 164 (8 %) of 2151 inpatients, and 23 (1 %) of 2090 healthy controls. AGE case-patients positive for HAdV were more likely to be < 3 years of age and more likely to report diarrhea (86 % vs 67 %) and dehydration (43 % vs 31 %) than HAdV-negative case-patients (p < 0.0001, all comparisons). Age did not differ significantly between HAdV-positive and negative controls. HAdV-positive AGE case-patients were less likely to have acute respiratory symptoms than HAdV-negative case-patients (8 % vs 18 %, p < 0.0001). The most frequently detected HAdV genotype was F41 (n = 106, 88 %). Other potential pathogens were detected in 36 % of HAdV-positive AGE case-patients and 43 % of controls; Clostridioides difficile was most common.
CONCLUSIONS: HAdV accounted for 8 % of medically attended AGE in both inpatient and ED settings in the U.S., primarily in young children. The majority of cases were type F41, which may inform future vaccine development.
