Popis: Background Influenza infection in children can be severe, resulting in complications such as pneumonia, but may be mitigated by early recognition and administration of antivirals. In this study, we identified risk factors for hospitalization and pneumonia in a pediatric population presenting with influenza-like illness (ILI) in Thailand. Methods Our study included pediatric patients (age < 18 years) presenting with ILI to inpatient and outpatient departments at a public hospital in Bangkok, Thailand, from 2009 to 2016. ILI was defined as fever plus cough or sore-throat, and pneumonia was defined as either lung radiographic or pulmonary examination abnormalities. Demographic and clinical data, as well as nasal and throat swabs, were collected during a one-time interview with patients presenting with ILI. Influenza infections were confirmed via RT-PCR testing of respiratory specimens. Retrospective chart review was used to collect data on individuals with influenza admitted for inpatient care. Results 5,968 children (33.6%) were enrolled with ILI, of whom 1,530 (25.6%) were confirmed to be influenza by RT-PCR, of which 25.5% were influenza A(H1N1)pdm09, 31.5% influenza A(H3N2), and 43.0% influenza B. 124 (8.1%) patients were admitted, and 41 of these children (33.1%) developed pneumonia. Predictors of hospitalization included younger age (4.1 yrs for inpatients vs. 5.6 yrs) and higher presenting temperature (38.6C for inpatient vs. 38.0C) (both P < 0.05). Among children hospitalized with influenza, influenza subtype was not associated with pneumonia risk. Co-detection of Klebsiella pneumoniae was associated with an increased risk of pneumonia (P < 0.05. Patients with pneumonia were younger (4.1 yrs with vs. 6.4 yrs, P = NS), had a longer interval from fever onset to presentation at the hospital, and required longer hospital stays. Risk of pneumonia was decreased in patients who received oseltamivir within 48 hours of fever onset (odds ratio 0.36, 95% confidence interval 0.16–0.91). Conclusion Post viral pneumonia is a potentially serious complication of influenza, requiring longer hospitalization stay and affecting more than one-third of hospitalized pediatric patients with influenza. The risk of pneumonia can be reduced with early presentation for clinical care and prompt administration of oseltamivir following fever onset. Disclosures All authors: No reported disclosures.
