Evolution of Treatment Modalities for Disseminated HAdV Infection in Neonates

Abstract

Human adenovirus (HAdV) infection in newborns is a rare condition that typically affects multiple organ systems and has a high mortality rate. We report a case of neonatal HAdV-D37 infection that presented with fever and respiratory distress that was confirmed by metagenomic next-generation sequencing using blood and bronchoalveolar lavage fluid. We treated the patient with intravenous immunoglobulin, methylprednisolone, and anticoagulants, and the patient recovered. Our review of 41 cases of HAdV found that treatment with intravenous immunoglobin might have improved the outcome of HAdV-D infection. We further suggest that glucocorticoid therapy may have additional therapeutic validity in the setting of severe or disseminated disease and that monitoring coagulation function and timely anticoagulation treatment should be considered to prevent complications associated with disseminated intravascular coagulation.
