Hyperinflammatory Syndrome in Children Associated With COVID-19: Need for Awareness

Area of Science:

• Pediatric infectious diseases
• Pediatric critical care
• Immunology

Background:

• COVID-19 initially presented as mild illness in children.
• A subset of pediatric patients develop a severe hyperinflammatory syndrome, Pediatric inflammatory multisystem syndrome - temporally associated with SARS-CoV-2 (PIMS-TS).
• PIMS-TS shares features with Kawasaki disease, toxic shock syndrome, and cytokine storm syndrome.

Purpose of the Study:

• To raise awareness among pediatricians regarding PIMS-TS.
• To provide current information on the clinical presentation and characteristics of PIMS-TS.
• To highlight the potential severity and need for intensive care in PIMS-TS cases.

Main Methods:

• Literature review and synthesis of current clinical data on PIMS-TS.
• Analysis of reported symptoms, diagnostic challenges, and potential pathogenesis.
• Compilation of information for clinical awareness and management guidance.

Main Results:

• PIMS-TS presents with persistent fever, inflammation, and multi-organ dysfunction.
• PCR testing for SARS-CoV-2 is often negative, but antibodies are usually present.
• Rapid deterioration and need for intensive care support are observed in some cases.

Conclusions:

• PIMS-TS is a significant post-COVID-19 complication in children requiring heightened clinical vigilance.
• Immune-mediated injury is suspected as the underlying pathogenesis.
• Increased awareness and understanding are essential for timely diagnosis and management of PIMS-TS.
