Abstract
Objectives: To describe the clinical profile and determine the factors affecting mortality of children admitted with adenovirus infection in a tertiary care centre in South India. Methods: In this observational study, respiratory specimens (nasopharyngeal swab / endotracheal aspirate) were collected from all hospitalized pediatric patients presenting with fever, cough, breathlessness, gastrointestinal symptoms, unexplained encephalopathy or multisystem involvement, between February 2023 and August 2023. Infection with adenovirus was determined by viral pathogen panel based on polymerase chain reaction (PCR) technique. Those referred from elsewhere with positive adenovirus report but non- availability of treatment details and children with coinfections were excluded. The clinical and laboratory profile of children with adenovirus infection were collected and predictors for in-hospital mortality were determined by logistic regression analysis. Results: Out of 527 children who were screened, 130 children with a median (IQR) age of 18 (10, 48) months, had adenovirus infection. 84.5% were aged below 5 years. 62 (41.33%) children required intensive care admission. Abnormal chest radiograph, multisystem involvement and non-respiratory illness were present in 90 (69.2%), 97 (74.62%) and 26 (20%) children. Complications included acute respiratory distress syndrome (n = 8), hemophagocytic lymphohistiocytosis (n = 7), left ventricular dysfunction (n = 11), acute liver cell failure (n = 7), acute kidney injury (n = 13), and multiorgan dysfunction (n = 16). Overall mortality was 13%. Acute kidney injury, left ventricular dysfunction and pancytopenia were identified as factors that may be significantly associated with death. Conclusions: Multisystem involvement was observed in majority of children presenting with adenovirus infection. Non-respiratory presentation is seen in a fifth of children with adenovirus infection.
