Background:
Patients requiring hospitalization to critical care units are at a higher risk for gastrointestinal (GI) bleeding. Although severe acute respiratory syndrome coronavirus 2 (SARS-COV-2) infection is predominantly a pulmonary disease, other serious manifestations including thromboembolic phenomenon are reported. Acute respiratory distress syndrome (ARDS) requiring mechanical ventilation, use of steroids and anticoagulation are all known to increase the risk of GI bleeding significantly.
Aim:
To study the incidence of GI bleeding and its impact on mortality in patients admitted with SARS-CoV-2.
Methods:
We retrospectively reviewed all patients admitted with SARS-CoV-2 from February 1, 2020 to April 15, 2020. We collected data including demographics, comorbid conditions, laboratory parameters, steroid and anticoagulant use. Coffee ground emesis, hematemesis, melena and hematochezia were defined as GI bleeding. All-cause mortality was reviewed for all patients included in the study. The relationship between GI bleeding and mortality was studied using logistic regression.
Results:
We had a total of 1206 patients hospitalized with SARS-CoV-2 infection with an all-cause mortality of 34% (n = 411). The overall incidence of GI bleeding was 3.1% (n = 37) with no significant difference between the patients who survived versus died during hospitalization (1.3% vs 1.5%, p = 0.77). Logistic regression analysis did not identify GI bleeding as an independent predictor of mortality. Therapeutic doses of anticoagulation were administered in 13.3% (n = 161) of patients, of which 6.8% (n = 11) developed GI bleeding. Patients were more likely to develop GI bleeding with use of therapeutic doses of anticoagulation (29.7% vs 12.8%, p = 0.003), steroids (37.8% vs 18.5%, p = 0.003) and mechanical ventilation (48.6% vs 30.4%, p = 0.018).
Conclusion:
Patients hospitalized with SARS-CoV-2 infection are at risk of gastrointestinal bleeding. Therapeutic doses of anticoagulation, mechanical ventilation and steroid use are significant risk factors for GI bleeding. However, GI bleeding did not significantly alter the mortality rates in SARS-CoV-2-infected patients.

Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...

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...

An acute ulcer, marked by superficial erosion and minimal inflammation, swiftly resolves upon identifying and addressing the underlying cause. In contrast, a chronic ulcer persists, potentially eroding through the muscular wall and forming fibrous tissue.
