COVID-19 and PIMS-Two Different Entities, but the Same Trigger

Area of Science:

• Pediatric infectious diseases
• Pediatric critical care medicine
• Pediatric rheumatology

Background:

• COVID-19 and Pediatric Inflammatory Multisystem Syndrome (PIMS) are distinct but similar pediatric conditions.
• Understanding their differences is crucial for effective patient management and long-term outcomes.

Purpose of the Study:

• To comparatively analyze symptoms, clinical findings, laboratory results, echocardiography, and evolution in children with SARS-CoV-2 infection versus PIMS.
• To identify key differentiating factors between these two pediatric pathologies.

Main Methods:

• A retrospective study comparing 46 children with COVID-19 and 20 children with confirmed PIMS.
• Assessment included clinical presentation, laboratory parameters, echocardiography, and complication analysis.

Main Results:

• Fever was more common in PIMS. COVID-19 cases showed higher bilirubin and creatinine. PIMS cases had higher hypoalbuminemia, elevated ESR, D-dimers, NT-proBNP, and CK-MB.
• PIMS group experienced more cardiac and liver impairment, and dehydration. Echocardiography revealed more pathological changes in PIMS patients.

Conclusions:

• Despite similarities, distinct clinical and laboratory features differentiate pediatric COVID-19 from PIMS.
• Accurate distinction is essential for guiding treatment and improving prognosis in affected children.
