title: A case of necrotizing enterocolitis associated with adenovirus infection in a term infant with 22q11 deletion syndrome.
abstract: Infections with adenoviruses are a common problem in the pediatric population. Normally asymptomatic to mild, those infections tend to take a more severe course in immunocompromised patients. 22q11 deletion syndrome (22q11DS) represents a common genetic disorder causing immunodeficiency from thymic hypoplasia or aplasia, heart defects, a characteristic facial appearance, and velopharyngeal dysfunction. Necrotizing enterocolitis (NEC) is a frequent gastrointestinal emergency observed in neonatal intensive care units. The occurrence of NEC is more prevalent in preterm infants. However, there are cases in term infants, but usually, they are associated with predisposing disorders. In this case report, a child is presented with 22q11DS that postnatally developed NEC associated with an adenoviral infection. Although other viruses such as toroviruses or cytomegaloviruses have been implicated in the pathogenesis of NEC in preterm infants, we could not find any report in the recent medical literature describing an association between adenoviral infections, NEC, and 22q11DS in a term infant.
