Gastrointestinal Bleeding in COVID-19 Patients: A Rapid Review

Gastrointestinal bleeding in patients with COVID-19: an integrative review

INTRODUCTION

In 2020, the world suffered a major impact from the COVID-19 pandemic, especially due to the high transmissibility of the virus. It is a disease that predominates with respiratory manifestations, but there is involvement of the gastrointestinal tract, causing symptoms ranging from mild to more severe. Highlighting gastrointestinal bleeding, it is a symptom resulting from the involvement of the SARS-CoV-2 virus described by several reports and case series.

METHODS

through an integrative literature review, of a qualitative nature, works that corresponded to the eligibility criteria were selected, totaling 16 articles included in this review.

RESULTS

of the patients who manifested gastrointestinal symptoms associated with the disease, common comorbidities and clinical manifestations were identified, in addition to therapies used to treat the infection, which were predisposing factors for the development of gastrointestinal bleeding.

CONCLUSION

The presence of gastrointestinal bleeding in patients with COVID-19 is established in the literature, since the pathophysiological mechanisms of the disease directly affect the GIT. Early recognition of symptoms and suspicion of gastrointestinal involvement allows better management of patients and complications.

Evolving Clinical Manifestations and Outcomes in COVID-19 Patients: A Comparative Analysis of SARS-CoV-2 Variant Waves in a Romanian Hospital Setting

The aim of this study was to evaluate differences in the clinical manifestations and outcomes in hospitalized patients with COVID-19 in a single Romanian center during four pandemic waves determined by different SARS-CoV-2 variants of concern (VOCs). A retrospective study on 9049 consecutive hospitalized adult patients was performed between 27 February 2020 and 31 March 2023. The study interval was divided into waves based on national data on SARS-CoV-2 VOCs' circulation. Multivariate logistic regression models were built, predicting death and complications as functions of comorbidities, therapy, wave, severity form, and vaccination status, and adjusted for ages ≥65 years. Pulmonary (pneumothorax/pneumomediastinum, pulmonary embolism) and extrapulmonary complications (liver injury, acute kidney injury, ischemic/hemorrhagic stroke, myocardial infarction, and gastrointestinal bleeding) were present, more frequently in ICU hospitalized patients and with differences between waves. The highest in-hospital mortality was found in patients presenting pneumothorax/pneumomediastinum. All of the evaluated risk factors were significantly associated with death, except for obesity and the Omicron wave. Our study highlights the changing nature of COVID-19 and acknowledges the impacts of viral mutations on disease outcomes. For all four waves, COVID-19 was a severe disease with a high risk of poor outcomes.

Spatiotemporal observations of host-pathogen interactions in mucosa during SARS-CoV-2 infection indicate a protective role of ILC2s

IMPORTANCE

Our study revealed the spatial interaction between humanized ACE2 and pseudovirus expressing Spike, emphasizing the role of type 2 innate lymphoid cells during the initial phase of viral infection. These findings provide a foundation for the development of mucosal vaccines and other treatment approaches for both pre- and post-infection management of coronavirus disease 2019.

Trends of Upper Gastrointestinal Bleeding Mortality in the United States Before and During the COVID-19 Era: Estimates From the Centers for Disease Control WONDER Database

Background

There have been reports of increased upper gastrointestinal bleeding (UGIB) in patients with coronavirus disease 2019 (COVID-19). Still, only a few studies have examined the mortality rate associated with UGIB in the United States before and during COVID-19. Hereby, we explored the trends of UGIB mortality in the United States before and during COVID-19. The study's objective was to investigate whether the COVID-19 pandemic significantly impacted UGIB mortality rates in the USA.

Methods

The decedents with UGIB were included. Age-standardized mortality rates were estimated with the indirect method using the 2000 US Census as the standard population. We utilized the deidentified data from the Centers for Disease Control and Prevention Wide-Ranging Online Data for Epidemiologic Research (CDC WONDER) database. Linear regression analysis was performed to determine 2021 projected mortality rates based on trends between 2012 and 2019 to quantify the association of the pandemic with UGIB-related deaths.

Results

The mortality rate increased from 3.3 per 100,000 to 4.3 per 100,000 among the population between 2012 and 2021. There was a significant increase in the overall mortality rate between each year and the following year from 2012 to 2019, ranging from 0.1 to 0.2 per 100,000, while the rise in the overall mortality rate between each year and 2021 ranges from 0.4 to 0.9 per 100,000.

Conclusions

Our results showed that the mortality rate increased among the population between 2012and 2021, suggesting a possible influence of COVID-19 infection on the incidence and mortality of UGIB.

Is Gastrointestinal Bleeding a Problem for COVID-19 Intensive Care Unit Patients?

The objective of this study was to describe the COVID-19 intensive care unit population and analyze the characteristics and outcomes of gastrointestinal bleeding patients. An observational prospective study design was used following the STROBE checklist. All patients admitted between February and April 2020 to the intensive care unit were included. Main outcome measures were first bleeding event timing, sociodemographic and clinical data before admission, and gastrointestinal symptoms. A total of 116 COVID-19 patients were included; 16 (13.8%) developed gastrointestinal bleeding, 15 were males (93.7%), and the median age was 65.64 ± 7.33 years. All 16 patients were mechanically ventilated, one (6.3%) already had gastrointestinal symptoms, 13 (81.3%) had at least one concomitant disease, and six (37.5%) died. Bleeding episodes occurred on a mean of 16.9 ± 9.5 days after admission. Nine cases (56.3%) had effects on their hemodynamics, hemoglobin levels, or transfusion requirements; six (37.5%) required diagnostic imaging; and two (12.5%) underwent endoscopy procedures. The Mann-Whitney test showed statistically significant differences between the two groups of patients concerning comorbidities. Gastrointestinal bleeding can occur in critically ill patients with COVID-19. Having a solid tumor or chronic liver disease seems to increase that risk. Nurses caring for COVID-19 patients are urged to individualize patients at higher risk in order to improve safety.

A descriptive study of abdominal complications in patients with mild COVID-19 presenting to the emergency department: a single-center experience in Japan during the omicron variant phase

BACKGROUND

COVID-19 is widely known to induce a variety of extrapulmonary manifestations. Gastrointestinal symptoms have been identified as the most common extra-pulmonary manifestations of COVID-19, with an incidence reported to range from 3 to 61%. Although previous reports have addressed abdominal complications with COVID-19, these have not been adequately elucidated for the omicron variant. The aim of our study was to clarify the diagnosis of concomitant abdominal diseases in patients with mild COVID-19 who presented to hospital with abdominal symptoms during the sixth and seventh waves of the pandemic of the omicron variant in Japan.

METHODS

This study was a retrospective, single-center, descriptive study. In total, 2291 consecutive patients with COVID-19 who visited the Department of Emergency and Critical Care Medicine, Kansai Medical University Medical Center, Osaka, Japan, between January 2022 and September 2022 were potentially eligible for the study. Patients delivered by ambulance or transferred from other hospitals were not included. We collected and described physical examination results, medical history, laboratory data, computed tomography findings and treatments. Data collected included diagnostic characteristics, abdominal symptoms, extra-abdominal symptoms and complicated diagnosis other than that of COVID-19 for abdominal symptoms.

RESULTS

Abdominal symptoms were present in 183 patients with COVID-19. The number of patients with each abdominal symptom were as follows: nausea and vomiting (86/183, 47%), abdominal pain (63/183, 34%), diarrhea (61/183, 33%), gastrointestinal bleeding (20/183, 11%) and anorexia (6/183, 3.3%). Of these patients, 17 were diagnosed as having acute hemorrhagic colitis, five had drug-induced adverse events, two had retroperitoneal hemorrhage, two had appendicitis, two had choledocholithiasis, two had constipation, and two had anuresis, among others. The localization of acute hemorrhagic colitis was the left-sided colon in all cases.

CONCLUSIONS

Our study showed that acute hemorrhagic colitis was characteristic in mild cases of the omicron variant of COVID-19 with gastrointestinal bleeding. When examining patients with mild COVID-19 with gastrointestinal bleeding, the potential for acute hemorrhagic colitis should be kept in mind.
