Angiotensin-Converting Enzyme 2 and Furin Expression in the Appendix of Children with COVID-19

Area of Science:

• Pediatric Medicine
• Virology
• Gastroenterology

Background:

• The COVID-19 pandemic, caused by SARS-CoV-2, has led to millions of deaths globally.
• SARS-CoV-2 can damage multiple organs, but its effect on the pediatric appendix remains unclear.
• Understanding SARS-CoV-2's impact on the appendix is crucial for comprehensive pediatric COVID-19 management.

Purpose of the Study:

• To investigate the presence of SARS-CoV-2 in pediatric appendix tissue.
• To evaluate the expression of ACE-2 and Furin genes in appendix samples from children with COVID-19.
• To assess the potential for SARS-CoV-2 infection within the appendix.

Main Methods:

• Real-time PCR was used to detect SARS-CoV-2 RNA in appendix tissue fragments from 42 children with confirmed COVID-19.
• Gene expression analysis was performed for ACE-2 and Furin, key host cell receptors for SARS-CoV-2.
• Correlation between viral presence and host factor expression was examined.

Main Results:

• SARS-CoV-2 genetic material was detected in the appendix tissue of children with COVID-19.
• Elevated expression of ACE-2 and Furin was observed in the appendix tissue.
• Findings indicate that the appendix may provide a suitable environment for SARS-CoV-2 replication.

Conclusions:

• The appendix can harbor SARS-CoV-2 in infected children.
• Increased ACE-2 and Furin expression in the appendix supports viral entry and infection.
• This study highlights the appendix as a potential site for SARS-CoV-2 viral load in pediatric cases.
