Insights
Severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) infection may trigger inflammatory bowel disease (IBD) in children. Two pediatric patients developed Crohn's disease after SARS-CoV-2 infection, responding well to standard IBD treatments.
Area of Science:
- Gastroenterology
- Infectious Diseases
- Immunology
Background:
- The coronavirus disease 2019 (COVID-19) pandemic has led to the emergence of various complications.
- COVID-19 can dysregulate immune responses, causing significant inflammation in some individuals.
- Inflammatory bowel disease (IBD) arises from immune dysregulation in genetically susceptible individuals, potentially triggered by environmental factors.
Abstract:
Since the coronavirus disease 2019 (COVID-19) outbreak caused by the severe acute respiratory syndrome-coronavirus-2 virus (SARS-CoV-2), various complications have been reported. Although most COVID-19 cases exhibited flu-like symptoms, COVID-19 may dysregulate the immune response and promote overwhelming levels of inflammation in some patients. Inflammatory bowel disease (IBD) is caused by dysregulated or inappropriate immune responses to environmental factors in a genetically susceptible host, and a SARS-CoV-2 infection may act as a possible cause of IBD. This paper describes two pediatric patients who developed Crohn's disease following a SARS-CoV-2 infection. They were previously healthy before the SARS-CoV-2 infection. On the other hand, they started to develop fever and gastrointestinal symptoms several weeks after recovery from the infection. They were diagnosed with Crohn's disease by imaging and endoscopic studies, and their symptoms improved after treatment with steroids and azathioprine. This paper suggests that a SARS-CoV-2 infection may trigger IBD in predisposed patients.

Inflammatory Bowel Disease II: Crohn's Disease
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
Crohn's disease
Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by transmural...
