Gastrointestinal symptoms in COVID-19.

SARS-CoV-2 infection manifests mainly by involving the respiratory system. Due to the presence of abdominal symptoms, the digestive system is clearly involved in the expression, transmission, and possible pathogenesis of COVID-19. There are many theories regarding the development of abdominal symptoms, including angiotensin 2 receptor, cytokine storm, and disturbances of the intestinal microbiome. This paper provides an overview of the most important meta-analyses and publications on gastrointestinal symptoms and the gut microbiome in COVID-19.

A Prospective Questionnaire-Based Study to Evaluate Factors Affecting the Decision to Receive COVID-19 Vaccination in 267 Patients with Inflammatory Bowel Disease in Poland.

BACKGROUND The aim of the study was to assess the rate of COVID-19 vaccination and the attitudes toward receiving COVID-19 vaccination among patients with inflammatory bowel disease (IBD) in Poland. An important aim of the study was to determine why some people get vaccinated and others refuse to do so. MATERIAL AND METHODS This was a single-center, prospective survey. The study included 267 IBD patients who agreed to complete an anonymous questionnaire comprising 31 questions. RESULTS We found that 71.2% of the IBD patients had been vaccinated. The history of COVID-19 was associated with a lower vaccination rate (16.9% vs 36.8%; P=0.001), regardless of IBD severity. In the vaccinated group, there were more vaccinated people among household members (90.4% vs 43.4%; p<0.001) and friends (52.9% vs 22.4%; P<0.001). Family safety (71.1%), the desire to avoid COVID-19 (67.9%), social responsibility (60.5%), the desire to return to normal life (51.6%), and faith in vaccination as such (43.2%) were the most common reasons for vaccination. The most common cause of non-vaccination was concern about adverse effects (50.0%), including long-term adverse effects (36.8%), and about the possible exacerbation of gastroenterological disease (34.2%). CONCLUSIONS IBD patients are more likely to be vaccinated against SARS-CoV-2 than the rest of the population in Poland. Young age, low socioeconomic status, low education, and living in the countryside were factors associated with lower vaccination rates. Family and friends had the greatest influence on the decision to vaccinate, but the influence of the mass media was very small.

Gastrointestinal symptoms in patients with coronavirus disease 2019 (COVID-19) - friend or foe?

Introduction: Gastrointestinal (GI) symptoms can be considered as a manifestation of coronavirus disease 2019 (COVID-19). Aim: Our study analysed GI symptoms depending on their occurrence, and their possible causes and impact on the course of COVID-19. Material and methods: A retrospective, single-centre assessment of the frequency, risk factors, and impact of GI symptoms in 441 patients with COVID-19. Results: A statistically significant reduction in the length of stay (LOS) (15 days vs. 17 days; p = 0.04), intensive care unit admission (ICU) (16.9% vs. 26.8%; p = 0.02), and need for mechanical ventilation (14.1% vs. 23.4%; p = 0.02) in the group who had experienced GI symptoms before hospitalization was noticed. For comparison, patients who developed GI symptoms during hospitalization had statistically significantly longer LOS (21 days vs. 15 days; p = 0.0001), were more frequently admitted to the ICU (38.1% vs. 18.6%; p = 0.0003), and had a higher need for mechanical ventilation (32.7% vs. 16.2%; p < 0.001). Risk factors for GI symptoms during hospitalization in COVID-19 patients included age, Clostridioides difficile infection, and receiving certain treatment (antibiotics and lopinavir + ritonavir). Conclusions: The GI symptoms that developed before admission to hospital correlated with reduced severity of the course of COVID-19. However, in the group of patients who developed GI symptoms during hospitalization, attention should be paid to concomitant treatment. The use of antibiotics should be limited because they are associated with the deterioration of the course of COVID-19; one of the reasons might be changes in the intestinal microbiome.

Irritable bowel syndrome following COVID-19: an underestimated consequence of SARS-CoV-2 infection.

INTRODUCTION: Gastrointestinal (GI) symptoms are a common manifestation of COVID­19. OBJECTIVES: We aimed to investigate whether GI symptoms persist in patients previously infected with SARS­CoV­2 in the form of post­infection irritable bowel syndrome (PI­IBS). PATIENTS AND METHODS: A prospective, single­center evaluation of questions regarding IBS was conducted using the Rome IV Adult Diagnostic Questionnaire among 257 patients previously hospitalized for COVID­19. RESULTS: GI symptoms (abdominal pain with diarrhea or constipation) were reported at the following time points: at discharge from the hospital, and after 3 and 6 months of follow­up. GI symptoms not meeting the full Rome IV diagnostic criteria for IBS due to too short symptom duration were reported by 28 individuals (10.6%) at hospital discharge, 58 (22.3%) after 3 months, and 70 (26.9%) after 6 months. The full Rome IV criteria for IBS were not met at discharge by any of the participants, but they were met after 3 and 6 months of follow­up in 14 (5.4%) and 15 individuals (5.8%), respectively. CONCLUSION: Persistent GI symptoms following COVID­19 are frequent and deserve significant and growing attention of gastroenterologists and other health care practitioners. The Rome IV criteria may be too strict to address the full spectrum of GI symptoms following COVID­19.

Social Distancing during COVID-19 Pandemic among Inflammatory Bowel Disease Patients.

(1) Background: Social distancing rules have been widely introduced in the fight against the coronavirus disease 2019 (COVID-19) pandemic. So far, the effectiveness of these methods has not been assessed in the group of inflammatory bowel disease (IBD) patients. (2) Methods: The study included 473 patients with IBD who made 1180 hospital visits from 1 May to 30 September 2020. During each visit, the patients completed a five-step, progressive scale that was developed to assess the degree of social isolation. In parallel, other demographic data were collected and the concentrations of anti-severe acute respiratory coronavirus 2 (SARS-CoV-2) IgG and IgM+IgA antibodies were measured using the ELISA method. (3) Results: The study found a significant correlation between the degree of social distancing and the presence of anti-SARS-CoV-2 antibodies in the groups with the lowest degree of isolation (3 to 5). (4) Conclusions: Maintaining social distancing is an effective method for reducing the spread of SARS-CoV-2 virus among IBD patients.

Inflammatory bowel disease is associated with higher seroprevalence rates of antibodies against SARS-CoV-2.

INTRODUCTION: According to the current data, there has been no increase in the incidence of COVID­19 in patients with inflammatory bowel disease (IBD). OBJECTIVES: The available data are based on symptomatic cases and do not include the asymptomatic ones. To measure the exact infection rate, we initiated a study that aimed to assess the seroprevalence of anti-SARS­CoV­2 antibodies in IBD. PATIENTS AND METHODS: A total of 864 individuals were enrolled in the study, including 432 patients with IBD (290 with Crohn disease and 142 with ulcerative colitis) and 432 controls without IBD (healthcare professionals) matched for age and sex. Serum samples were prospectively collected, and the presence of anti-SARS­CoV­2 immunoglobulin (Ig) G and IgM + IgA antibodies were measured using the enzyme­linked immunoassay method (Vircell Microbiologists). RESULTS: A significantly higher percentage of positive results for anti-SARS­CoV­2 antibodies, both in the IgG and IgM + IgA class, was found in patients with IBD (4.6% and 6%, respectively, compared with 1.6% and 1.1%, respectively, in controls; both P values <0.05). No patient had symptomatic COVID­19. There was no association among patients' age, sex, drugs used for IBD, or disease activity and the occurrence of IgG antibodies. CONCLUSION: Patients with IBD may be at higher risk of developing SARS­CoV­2 infection, defined as the presence of elevated levels of anti-SARS­CoV­2 IgG antibodies, but not of having a symptomatic and / or severe course of COVID­19 compared with healthcare professionals without IBD.

Clostridioides difficile infection in coronavirus disease 2019 (COVID-19): an underestimated problem?

INTRODUCTION: The use of antibiotics and possibility of microbiota disruption during the coronavirus disease 2019 (COVID­19) pandemic have raised questions about the incidence of Clostridioides difficile infection (CDI). OBJECTIVES: This study aimed to assess the frequency of and risk factors for CDI in patients with COVID­19. PATIENTS AND METHODS: We conducted a retrospective, single­center evaluation study on the frequency of and risk factors for CDI in patients with COVID­19 and in the prepandemic era. The analysis included 441 patients with severe acute respiratory syndrome coronavirus 2 (SARS­CoV­2) infection and 2961 pa­ tients hospitalized before the pandemic. RESULTS: A significant increase in the incidence of CDI was noted during the COVID­19 pandemic compared with the prepandemic period: 10.9% versus 2.6%, P <0.001. Risk factors for CDI in patients with COVID­19 included: age, length of hospital stay, occurrence of diarrhea during hospitalization, use of antibiotics other than azithromycin, and coexistence of nervous system disease or chronic kidney disease-all of these factos had a weak association with CDI development. The multivariable logistic regression model indicated other unassessed variables that had an impact on the CDI incidence rate. CONCLUSIONS: We observed a higher incidence of CDI in patients with COVID­19. Antibiotic therapy was a relevant risk factor for CDI, although its effect was weak. Other drugs used during the pandemic were not found to have an impact on disease development. Possible causes of CDI may include fecal microbiota disruption by SARS­CoV­2 infection, but further research is needed to validate this hypothesis.

Convalescent plasma treatment is associated with lower mortality and better outcomes in high-risk COVID-19 patients - propensity-score matched case-control study.

OBJECTIVE: This study aimed to investigate the efficacy and safety of convalescent plasma (CP) transfusion in a group of high-risk COVID-19 patients. METHODS: This prospective study included 204 patients from a single tertiary-care hospital, hospitalized with COVID-19, of whom 102 were treated with CP administration and standard care (PG) and 102 others who received standard care only (CG). The CG was selected from 336 hospitalized patients using the propensity-score matching (PSM) technique using age, MEWS score, and comorbidities. The primary outcome was mortality rate; secondary outcomes were the requirement of a ventilator, length of ventilator need, length of intensive care unit (ICU) stay, and length of overall hospital confinement. Additionally, parameters predicting death in COVID-19 patients were identified. RESULTS: Findings confirmed a significantly lower mortality rate in the PG versus the CG (13.7% vs. 34.3 %, p = 0.001) and a significant difference in the cumulative incidence of death between the two groups (p < 0.001). CP treatment was associated with lower risk of death (OR = 0.25 CI95 [0.06; 0.91], p = 0.041). There were no significant differences in ICU stay, ventilator time, and hospitalization time between the two groups. CONCLUSIONS: A significantly lower mortality rate was observed in the group of patients treated with CP. Age, presence of cardiac insufficiency, active cancer, a ventilator requirement, and length of hospitalization significantly increased the risk of death in both groups. Our study shows that CP affords better outcomes when administrated in the earlier stage of high-risk COVID-19 disease.

Skin and gastrointestinal symptoms in COVID-19.

INTRODUCTION: The first cases of coronavirus disease 2019 (COVID-19) were noted in December 2019 in Wuhan province, China. The World Health Organisation (WHO) announced the pandemic status on March 11, 2020. The manifestations of the disease are as follows: fever, cough, fatigue, anosmia and ageusia, dyspnoea, chest pain, muscle soreness, chills, sore throat, rhinitis, headache, gastrointestinal (GI) symptoms, and dermal lesions. AIM: To evaluate the relationship between dermal lesions and GI symptoms in a group of COVID-19 patients. MATERIAL AND METHODS: A group of 441 COVID-19 patients admitted to the Central Clinical Hospital of the Ministry of the Interior and Administration in Warsaw between March 15th and June 15th, 2020. RESULTS: Of 441 patients with confirmed SARS-CoV-2 infection, 255 (58.5%) experienced gastrointestinal (GI) symptoms: lack of appetite was reported in 124 (48.6%) cases, diarrhoea was noted in 109 (42.7%), abdominal pain in 95 (37.3%), vomiting in 37 (14.5%), and nausea in 32 (12.5%) cases. Eight (1.81%) patients had dermal lesions: erythematous macular lesions (2 patients - 25%), erythematous infiltrated lesions (2; 25%), erythematous infiltrated and exfoliative lesions (3; 37.5%), erythematous papular lesions (3; 37.5%), and erythematous oedematous lesions (2; 25%). All of those patients reported gastrointestinal symptoms during the hospitalisation. CONCLUSIONS: The following study analyses possible causes of dermal lesions and their coexistence with GI symptoms. Several possible theories were taken into account, including the microbiota alterations and issue of drug-related complications.

Approach to endoscopic procedures during COVID-19 pandemic - not as expected.

The SARS-CoV-2 epidemic and ensuing transformation of the Central Clinical Hospital of the Ministry of the Interior and Administration in Warsaw into one of the largest specialist infection disease hospitals in Poland imposed a complete reorganisation of work, including in the endoscopy unit. For the vast majority of hospitalised patients, COVID-19 infection posed an extra burden in addition to already known and treated chronic disorders. Therefore, the work schedule and infrastructure have been rearranged in order to minimise the risk of transmission of infection to the personnel as well as to ensure continuous preparedness to perform all endoscopic procedures in patients infected with or suspected of SARS-CoV-2 infection. Between 16.03.2020 and 20.07.2020 we performed 91 endoscopic procedures involving the upper and lower gastrointestinal tract. The majority of those procedures were performed for urgent indications and as a part of on-call duties. The scope of endoscopic procedures was much broader than initially anticipated at the beginning of the epidemic, indicating the need for a change in the recommendations in that regard. Thanks to the application of appropriate procedures and personal protective equipment (PPE) there were no cases of infection among the employees of the Endoscopy Unit coming in direct contact with patients during the above-mentioned period.

Addressing multiple gastroenterological aspects of coronavirus disease 2019.

The outbreak of the coronavirus disease 2019 (COVID­19) pandemic has become the biggest challenge for the whole human community since many years. It seems that the proper identification of all people infected with severe acute respiratory syndrome coronavirus 2 (SARS­CoV­2) is the best strategy to limit the transmission. However, in a significant proportion of patients, there are no clinical manifestations of the disease, and symptoms may be very mild or atypical. There is a growing body of evidence that digestive manifestations of COVID­19 are frequently reported and may precede typical respiratory symptoms. Moreover, SARS­CoV­2 particles were found in the gastrointestinal epithelial cells, and viral RNA was detected in the feces of patients with COVID­19. These data suggest that gastrointestinal symptoms in COVID­19 are not accidental findings and they may result from direct digestive involvement. Patients with new­onset diarrhea, abdominal pain, nausea, and vomiting without any other evident etiological factors should be tested for SARS­CoV­2 infection. Gastroenterologists and members of other medical specialties should also remember that the current epidemiological situation has changed diagnostic and therapeutic algorithms in the management of several gastrointestinal and liver disorders. This review article summarizes the currently available data on multiple gastroenterological aspects of COVID­19 and provides information on practical recommendations and position statements of the most prominent associations in the field of gastroenterology, which appeared in response to the emergence of the pandemic.
