Insights
The SARS-CoV-2 Delta variant caused severe respiratory illness in infants, with many requiring mechanical ventilation and some succumbing to the infection. This highlights the critical impact of the Delta variant on vulnerable pediatric populations.
Area of Science:
- Pediatric Intensive Care
- Infectious Diseases
- Virology
Background:
- Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) typically causes mild to moderate symptoms in children.
- Limited clinical data exists on the specific symptoms and outcomes of the Delta variant in pediatric patients, particularly infants.
Approach:
- A retrospective study was conducted between June 23, 2021, and August 16, 2021, during the Delta variant's predominance.
- Infants under 15 years old admitted to the pediatric intensive care unit (PICU) with severe or critical SARS-CoV-2 infection (confirmed by RT-PCR) were included.
- Medical records were reviewed to gather clinical characteristics and outcomes.
Key Points:
- Twenty infants, with a median age of 47 days and no underlying conditions, were included.
- Respiratory involvement, including pediatric acute respiratory distress (PARDS), was the primary clinical feature.
- Eleven patients developed PARDS, with 7 requiring mechanical ventilation, and 4 patients died.
Conclusions:
- The SARS-CoV-2 Delta variant can cause life-threatening illness in very young infants, even those without comorbidities.
- This case series underscores the severe respiratory and hemodynamic impact of the Delta variant in a vulnerable pediatric population.
- Findings emphasize the need for vigilant monitoring and management strategies for infants during periods of high SARS-CoV-2 variant circulation.
Background:
SARS-CoV-2 is described to cause mild to moderate symptoms in children. To date, clinical data and symptoms of the Delta variant in pediatric patients are lacking.
Aim:
To describe clinical characteristics and outcomes of infants admitted in the pediatric intensive care unit (PICU) during the period of Delta variant predominance.
Methods:
We performed a retrospective study, between June 23, 2021 and August 16, 2021. We included children aged under 15 years, admitted to PICU with severe and critical form of SARS-CoV-2 infection as confirmed by RT-PCR. We reviewed medical records for all patients.
Results:
During the study period, 20 infants were included. The median age was 47 days (IQR: 26.5-77). The sex ratio was 0.8 (9 males). No underlying medical conditions were noted. Parents were not vaccinated. Respiratory involvement was the main feature to be observed in our cohort. Eleven patients had pediatric acute respiratory distress (PARDS) with a median oxygen saturation index (OSI) of 9 (IQR: 7-11). PARDS was mild in 4 cases, moderate in 5 cases and severe in 2 cases. Hemodynamic instability was observed in 4 cases. The main radiological finding was ground glass opacities in 11 cases. Seventeen patients were mechanically ventilated and 3 of them were escalated to high-frequency oscillatory ventilation. The median duration of mechanical ventilation was 6 days (IQR 2.5-12.5). The remaining patients were managed with high flow nasal cannula. Four patients died.
Conclusion:
We report herein a case series of very young infants, with no comorbidities, and with a life-threatening illness due to SARS-CoV-2 Delta variant.
