Viral respiratory infections are a leading cause of illness and hospitalization in young children worldwide. Case fatality rates in pediatric patients with adenoviral lower respiratory tract infection requiring intensive care unit (ICU) admission have been reported between 7 and 22%. We investigated the demographics and clinical characteristics in pediatric mortalities associated with adenoviral respiratory infection at 12 academic children's hospitals in the United States. There were 107 mortality cases included in our study, 73% of which had a chronic medical condition. The most common chronic medical condition was immunocompromised state in 37 cases (35%). The incidences of pediatric acute respiratory distress syndrome (78%) and multiple organ dysfunction syndrome (94%) were profound. Immunocompetent cases were more likely to receive mechanical ventilation within the first hour of ICU admission (60 vs. 14%, p < 0.001) and extracorporeal membrane oxygenation (27 vs. 5%, p = 0.009), and less likely to receive continuous renal replacement therapy (20 vs. 49%, p = 0.002) or have renal dysfunction (54 vs. 78%, p = 0.014) as compared with immunocompromised cases. Immunocompromised cases were more likely to have bacteremia (57 vs. 16%, p < 0.001) and adenoviremia (51 vs. 17%, p < 0.001) and be treated with antiviral medications (81 vs. 26%, p < 0.001). We observed a high burden of nonrespiratory organ system dysfunction in a cohort of pediatric case fatalities with adenoviral respiratory infection. The majority of cases had a chronic medical condition associated with an increased risk of complications from viral respiratory illness, most notably immunocompromised state. Important treatment differences were noted between immunocompromised and immunocompetent cases.
Acute kidney injury (AKI), particularly of greater severity and longer duration, is associated with increased morbidity and mortality in the pediatric population. AKI frequently occurs during sepsis, yet the knowledge of risk factors for sepsis-associated AKI in the PICU is limited. We aimed to identify risk factors for AKI that develops or persists after 72 hours from sepsis recognition in pediatric patients with severe sepsis.
Objective The aim of this study was to determine the prevalence and taxonomy of pathogen codetection in pediatric case fatalities associated with adenoviral respiratory infection.
Methods This retrospective case series included 107 pediatric case fatalities associated with adenoviral respiratory infection.
Results We observed a high rate of pathogen codetection with broad diversity from both respiratory and nonrespiratory sources. We noted differences in codetection characteristics based on immune status; most notably that immunocompromised cases were more likely to have bacteremia and adenoviremia.
Conclusions In pediatric case fatalities associated with adenoviral respiratory infection, we observed a high degree of pathogen codetection.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
