Background: The Omicron variant of SARS-CoV-2 has been associated with unique clinical presentations in children, including croup-like symptoms such as barking cough, hoarseness, and respiratory distress. This study aimed to compare the clinical, laboratory, and treatment characteristics of hospitalized pediatric patients with croup who tested positive or negative for COVID-19 during the Omicron wave.
Methods: A retrospective, descriptive-analytical study was conducted on 111 pediatric patients hospitalized with croup at Bahrami Children's Hospital and the Children's Medical Center in Iran from January 21 to March 20, 2022. Patients were categorized into two groups: PCR-positive (Omicron group, n = 30) and PCR-negative (non-Omicron group, n = 81). Data on demographics, clinical severity, laboratory indices, treatments, and outcomes were extracted and analyzed using SPSS version 20.
Results: The mean age of the Omicron group was significantly younger (16.93 ± 24.80 months) compared to the non-Omicron group (32.58 ± 37.26 months; p = 0.049). Symptom severity was higher in the Omicron group, with moderate to severe symptoms observed in 73.4% of patients, compared to 32.1% in the non-Omicron group (p = 0.001). The Omicron group had longer hospital stays (2.59 ± 3.93 vs. 2.11 ± 2.75 days; p = 0.016) and required more nebulized epinephrine (2.47 ± 1.27 vs. 1.77 ± 1.003 days; p = 0.003) and repeat corticosteroid doses (83.3% vs. 38.3%; p = 0.0001). Laboratory findings showed no significant differences between the groups (all p > 0.05).
Conclusion: Children with croup during the Omicron surge exhibited increased symptom severity, required more intensive treatment, and experienced longer hospital stays compared to those without COVID-19. These findings emphasize the need for heightened clinical awareness and tailored management strategies for Omicron-related croup in pediatric populations.
