Controversies in the therapeutic approach to congenital cytomegalovirus infection

摘要

Treatment of congenital cytomegalovirus infection is mandatory in cases with severe systemic and/or neurological involvement. However, some patients are paucisymptomatic, with very subtle systemic manifestations and/or minimal brain alterations. Current international guidelines do not clearly state whether these children should be treated, and this decision is not straightforward for clinicians. Of a small series of six infants with congenital cytomegalovirus infection admitted to our neonatal unit between 2015 and 2019, half showed paucisymptomatic neurological manifestations. In these cases, the determination of ss2-microglobulin in cerebrospinal fluid and magnetic resonance imaging aided in the decision-making concerning the therapeutic approach to follow.
