ImportanceSARS-CoV-2 infection is associated with persistent, relapsing, or new symptoms or other health effects occurring after acute infection, termed postacute sequelae of SARS-CoV-2 infection (PASC), also known as long COVID. Characterizing PASC requires analysis of prospectively and uniformly collected data from diverse uninfected and infected individuals.ObjectiveTo develop a definition of PASC using self-reported symptoms and describe PASC frequencies across cohorts, vaccination status, and number of infections.Design, Setting, and ParticipantsProspective observational cohort study of adults with and without SARS-CoV-2 infection at 85 enrolling sites (hospitals, health centers, community organizations) located in 33 states plus Washington, DC, and Puerto Rico. Participants who were enrolled in the RECOVER adult cohort before April 10, 2023, completed a symptom survey 6 months or more after acute symptom onset or test date. Selection included population-based, volunteer, and convenience sampling.ExposureSARS-CoV-2 infection.Main Outcomes and MeasuresPASC and 44 participant-reported symptoms (with severity thresholds).ResultsA total of 9764 participants (89% SARS-CoV-2 infected; 71% female; 16% Hispanic/Latino; 15% non-Hispanic Black; median age, 47 years [IQR, 35-60]) met selection criteria. Adjusted odds ratios were 1.5 or greater (infected vs uninfected participants) for 37 symptoms. Symptoms contributing to PASC score included postexertional malaise, fatigue, brain fog, dizziness, gastrointestinal symptoms, palpitations, changes in sexual desire or capacity, loss of or change in smell or taste, thirst, chronic cough, chest pain, and abnormal movements. Among 2231 participants first infected on or after December 1, 2021, and enrolled within 30 days of infection, 224 (10% [95% CI, 8.8%-11%]) were PASC positive at 6 months.Conclusions and RelevanceA definition of PASC was developed based on symptoms in a prospective cohort study. As a first step to providing a framework for other investigations, iterative refinement that further incorporates other clinical features is needed to support actionable definitions of PASC.
In the United States, an estimated 7.3% of confirmed cases of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection (COVID-19) are among persons aged less than 18 years. Data regarding clinical manifestations in this age group are still evolving. An upper airway predilection has been reported in children. We describe the case of a 15-year-old female with supraglottitis and unilateral hypomobility of vocal cord with concern for critical airway, associated with COVID-19. She was managed by a multidisciplinary team including critical care, infectious diseases, and otolaryngology. This report adds to the sparse but evolving body of literature on the clinical presentation of COVID-19 disease in children.
In this study, we describe the characteristics and outcomes of pediatric necrotizing pneumonia in the United States. DESIGN AND SETTING:A retrospective analysis of the Healthcare Cost and Utilization Project 2016 Kids Inpatient Database was performed. The Kids Inpatient Database is a large deidentified hospital discharge database of pediatric patients in the United States. PATIENTS:The database was filtered using International Classification of Diseases, 10th Edition code J85.0 to identify necrotizing pneumonia in children 28 days to 20 years old. INTERVENTIONS:Children with necrotizing pneumonia with and without bacterial isolation and with and without complex chronic conditions were compared. Sample weighting was employed to produce national estimates. MEASUREMENTS AND MAIN RESULTS:Of the 2,296,220 discharges, 746 patients had necrotizing pneumonia (prevalence: 3.2/10,000 discharges). In patients with necrotizing pneumonia, 46.6% required chest tubes, 6.1% underwent video-assisted thoracoscopic surgery, and 27.6% were mechanically ventilated. Pneumothorax was identified in 16.7% and pyothorax in 27.4%. The overall mortality rate was 4.1% (n = 31). Bacterial isolation was documented in 40.9%. The leading organisms identified in patients without a complex chronic condition were Streptococcus pneumoniae (12.6%) and Staphylococcus aureus (9.2%) and in patients with a complex chronic condition were S. aureus (13.4%) and Pseudomonas aeruginosa (12.8%). Patients with bacterial isolation were significantly more likely to develop pneumothorax (odds ratio, 2.6; CI, 1.6-4.2) or septic shock (odds ratio, 3.2; CI, 1.9-5.4) and require a chest tube (odds ratio, 2.5; CI, 1.7-3.5) or mechanical ventilation (odds ratio, 2.3; CI, 1.5-3.3) than patients without bacterial isolation.CONCLUSIONS: Bacterial etiology of necrotizing pneumonia in children varied with the presence or absence of a complex chronic condition. Bacterial isolation is associated with increased invasive procedures and complications. The mortality rate is higher in children with complex chronic conditions. This study provides national data on necrotizing pneumonia among hospitalized children.
