Somatic, emotional, and gastrointestinal symptom severity are increased among children and adolescents with COVID-19

Post-infectious disorders of gut-brain interaction (PI-DGBI) have significant impact on children and adolescents. The effect of COVID-19 on PI-DGBI-associated symptoms in this population, however, is unknown.

We performed electronic medical record searches to identify patients 8-17 years old with a SARS-CoV2 PCR test at Lurie Children's Hospital between November 2020 and March 2021 (cohort 1) and April-October 2021 (cohort 2). Questionnaires were administered to assess symptoms prior to and 3 months following the test. This included the Pediatric Eosinophilic Esophagitis Symptom Score (PEESS), questionnaire of pediatric gastrointestinal symptoms-Rome IV, Nausea Profile (NP), dyspepsia symptom survey (DSS), nausea severity profile (NSP), and Pediatric Quality of Life Inventory (PedsQL). We grouped patients based on the presence of symptoms prior to COVID-19 test or the test result.

One hundred and ninety-six parent(s) or guardian(s) in cohort 1 and 274 in cohort 2 completed surveys and self-reported their child's COVID-19 result. Cohort 1 had increased PEESS and DSS scores, lower PedsQL scores, and increased frequency of abdominal pain disorders among patients with symptoms prior to COVID-19 testing. Both cohorts had increased NP and NSP scores among patients with symptoms prior to COVID-19 testing that was highest among patients with a positive COVID-19 test. Abdominal pain and diarrhea prior to COVID-19 testing predicted higher NP scores.

Among symptomatic COVID-19 tested children, we found increased severity of nausea-associated somatic, emotional, and gastrointestinal symptoms in the 3 months following the test that was most increased among patients with a positive COVID-19 test.
