Clinical characteristics and factors associated with severe acute respiratory infection and influenza among children in Jingzhou, China.

ABSTRACT:

Background

Influenza is an important cause of respiratory illness in children, but data are limited on hospitalized children with laboratory-confirmed influenza in China.

Methods

We conducted active surveillance for severe acute respiratory infection (SARI; fever and at least one sign or symptom of acute respiratory illness) among hospitalized pediatric patients in Jingzhou, Hubei Province, from April 2010 to April 2012. Data were collected from enrolled SARI patients on demographics, underlying health conditions, clinical course of illness, and outcomes. Nasal swabs were collected and tested for influenza viruses by reverse transcription polymerase chain reaction. We described the clinical and epidemiological characteristics of children with influenza and analyzed the association between potential risk factors and SARI patients with influenza.

Results

During the study period, 15 354 children aged <15 years with signs and symptoms of SARI were enrolled at hospital admission. severe acute respiratory infection patients aged 5-15 years with confirmed influenza (H3N2) infection were more likely than children without influenza to have radiographic diagnosis of pneumonia (11/31, 36% vs 15/105, 14%. P<.05). Only 16% (1116/7145) of enrolled patients had received seasonal trivalent influenza vaccination within 12 months of hospital admission. Non-vaccinated influenza cases were more likely than vaccinated influenza cases to have pneumonia (31/133, 23% vs 37/256, 15%, P<.05). severe acute respiratory infection cases aged 5-15 years diagnosed with influenza were also more likely to have a household member who smoked cigarettes compared with SARI cases without a smoking household member (54/208, 26% vs 158/960, 16%, P<.05).

Conclusions

Influenza A (H3N2) virus infection was an important contributor to pneumonia requiring hospitalization. Our results highlight the importance of surveillance in identifying factors for influenza hospitalization, monitoring adherence to influenza prevention and treatment strategies, and evaluating the disease burden among hospitalized pediatric SARI patients. Influenza vaccination promotion should target children.

Project description:ObjectivesSevere acute respiratory syndrome coronavirus-2 affects adults disproportionately more than children. A small proportion of children with severe acute respiratory syndrome coronavirus-2 required admission to a PICU. We describe the nationwide U.K. PICU experience of severe acute respiratory syndrome coronavirus-2 infection during the first wave of the pandemic and compare this with the critical care course of the 2019 influenza cohort.DesignProspective nationwide cohort study of characteristics of severe acute respiratory syndrome coronavirus-2-positive children. Data collection utilized routine Pediatric Intensive Care Audit Network and severe acute respiratory syndrome coronavirus-2-specific data.SettingAll U.K. PICUs.PatientsChildren less than 18 years old, admitted to U.K. PICUs between March 14, 2020, and June 13, 2020, and a positive severe acute respiratory syndrome coronavirus-2 polymerase chain reaction. Children admitted to U.K. PICUs in 2019 with influenza provided comparison.InterventionsNone.Measurements and main resultsWe identified 76 PICU admissions among 73 children with a positive severe acute respiratory syndrome coronavirus-2 polymerase chain reaction test. Prevalence of PICU admissions per million was 5.2 for children versus 260 for adults. Ten children (14%) were identified on routine screening. Seventeen children (23%) had pediatric inflammatory multisystem syndrome temporally associated with severe acute respiratory syndrome coronavirus-2. Seventeen (23%) had coinfections. Invasive ventilation was required in seven of 17 children (41%) with pediatric inflammatory multisystem syndrome temporally associated with severe acute respiratory syndrome coronavirus-2 versus 38 of 56 other severe acute respiratory syndrome coronavirus-2 positive children (68%), with 77% requiring vasoactive support versus 43%, respectively. Seven children (10%) died. In comparison with influenza children, severe acute respiratory syndrome coronavirus-2 children were older (median [interquartile range]: 10 [1-13] vs 3 yr [1-8 yr]), more often Black or Asian (52% v 18%), higher weight z score (0.29 [-0.80 to 1.62] vs -0.41 [-1.37 to 0.63]), and higher deprivation index (3.3 [-1 to 6.3] vs 1.2 [-1.8 to 4.4]). Comorbidities, frequency of organ supports, and length of stay were similar.ConclusionsThis nationwide study confirms that PICU admissions with severe acute respiratory syndrome coronavirus-2 infections were infrequent. We have reported similarities and differences in sociodemographic characteristics, organ support interventions, and outcomes of children affected by severe acute respiratory syndrome coronavirus-2 compared with influenza.
