Insights
Coronavirus disease 2019 (COVID-19) can affect the liver and gastrointestinal tract, impacting patient outcomes. This review details these extra-pulmonary manifestations and proposes preventive measures for endoscopy units.
Area of Science:
- Gastroenterology and Hepatology
- Infectious Diseases
- Virology
Background:
- Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) causes COVID-19, a global pandemic.
- While primarily respiratory, SARS-CoV-2 infection presents with extra-pulmonary manifestations.
- Hepatic and gastrointestinal involvement are increasingly recognized complications of COVID-19.
Purpose of the Study:
- To summarize the characteristics and potential mechanisms of liver and gastrointestinal involvement in SARS-CoV-2 infection.
- To enhance understanding of the full spectrum of COVID-19 manifestations.
- To propose preventive strategies for endoscopy departments to mitigate SARS-CoV-2 transmission.
Main Methods:
- Literature review of studies on SARS-CoV-2 and gastrointestinal/hepatic manifestations.
- Analysis of reported clinical characteristics and etiological explanations.
- Synthesis of evidence regarding preventive measures in endoscopic settings.
Main Results:
- SARS-CoV-2 infection can lead to diverse hepatic and gastrointestinal symptoms.
- Potential mechanisms include direct viral invasion, immune-mediated injury, and drug toxicity.
- Pre-existing liver or digestive conditions may worsen COVID-19 prognosis.
Conclusions:
- Hepatic and gastrointestinal involvement are significant extra-pulmonary complications of COVID-19.
- Understanding these manifestations is crucial for disease management and prognosis.
- Implementing specific preventive measures in endoscopy is vital to control viral spread.
Abstract:
Since December 2019, the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the causative pathogen of coronavirus disease 2019 (COVID-19), has posed a serious threat to global health and is currently causing a major pandemic. While patients typically present with fever and a respiratory illness, mounting evidence indicates that patients might also report extra-pulmonary manifestations, including those affecting the liver and gastrointestinal tract. This involvement may have important implications to the disease management, transmission, and prognosis, especially in patients with pre-existing hepatic or digestive co-morbidities. In this review, the characteristics and possible explanations of hepatic and gastrointestinal involvement caused by SARS-CoV-2 infection are summarized, adding to our knowledge of the spectrum of COVID-19. In addition, preventive measures implemented in endoscopy departments to prevent further dissemination of SARS-CoV-2 infection are proposed.

Clinical manifestations of acute gastritis
The patient with acute gastritis may have a rapid onset of symptoms, such as epigastric pain or discomfort, dyspepsia, anorexia, hiccups, or nausea and vomiting, which can last from a few hours to a few days. Erosive or hemorrhagic gastritis may cause bleeding, which may manifest as blood in vomit or as...
