Impact of COVID-19 on inflammatory bowel disease practice and perspectives for the future

Differential Gene Expression Profiles Involved in the Inflammations Due to COVID-19 and Inflammatory Bowel Diseases and the Investigation of Predictive Biomarkers

Gastrointestinal manifestations in COVID-19 were attributed to 74-86% of the hospitalised patients due to severe or prolonged pathogenesis. Though it is a respiratory disease, the impact it elicits on the gastrointestinal tract and brain are intense. Inflammatory bowel disease including Crohn's disease and ulcerative colitis are idiopathic inflammatory disorders of the gastrointestinal tract. The intrinsic mechanisms involved in gut inflammations due to a respiratory viral disease can be deciphered when the gene expression profiles of COVID-19 and IBD are compared. The current study utilises an integrated bioinformatics approach to unravel them. The publicly available gene expression profiles of colon transcriptomes infected with COVID-19, Crohn's disease and Ulcerative colitis were retrieved, integrated and analysed for the identification of differentially expressed genes. The inter-relational analysis along with gene annotation and pathway enrichment detailed the functional and metabolic pathways of the genes during normal and diseased conditions. The protein-protein interactions deduced from the STRING database and the identified hub genes predicted potential biomarker candidates for COVID-19, Crohn's disease and ulcerative colitis. The inflammatory response pathways were upregulated and enrichment of chemokine signalling, altered lipid metabolism, coagulation and complement cascades were seen in all three conditions along with impaired transport mechanisms. CXCL11, MMP10, and CFB are predicted to be overexpressed biomarkers, whilst GUCA2A, SLC13A2, CEACAM, and IGSF9 as downregulated novel biomarker candidates for colon inflammations. The three miRNAs hsa-miR-16-5p, hsa-miR-21-5p, and hsa-miR-27b-5p exhibited significant interactions with the upregulated hub genes and four long non-coding RNAs NEAT1, KCNQ1OT1, and LINC00852 capable of regulating miRNA were also predicted. This study offers significant information on the underlying molecular mechanisms of inflammatory bowel disease with identification of potential biomarkers.

The Impact of the COVID-19 Pandemic on Patients with Ulcerative Colitis: Results from a Global Ulcerative Colitis Narrative Patient Survey

INTRODUCTION

The coronavirus disease 2019 (COVID-19) pandemic created challenges related to disease management of patients with ulcerative colitis (UC).

METHODS

The UC Narrative COVID-19 survey was conducted from August to December 2021 among adults with UC from the United States, Canada, Japan, France, and Finland. Patients were questioned on disease management, health care access and experience, and preferences for interactions with their doctor. Data were analyzed descriptively.

RESULTS

In total, 584 patients qualified for and completed the survey. Compared with 2019, 25% experienced more flares during the pandemic (from early 2020). Most patients (88%) taking prescription medication were very/somewhat satisfied with their current treatment plan; 53% were hesitant to make changes during the pandemic. Factors that patients agreed helped control UC symptoms during the pandemic included fewer social outings (37%), working from home (29%), and less busy schedules (28%). Greater anxiety/stress (43%) and hesitancy to visit a hospital/office (34%) made the control of UC symptoms more difficult. Compared with 2019, more patients relied on certain alternative support systems during the pandemic. Patients who used in-person and virtual appointments were equally very satisfied/satisfied with the quality of care (both 81%). In-person appointments were preferred by 68% of patients when meeting a new doctor, 55% when experiencing a flare, and 52% for regular check-ups; 41% preferred virtual appointments for UC prescription refills.

CONCLUSION

During the pandemic, most patients were satisfied with their current UC treatment plan and access to care; more patients relied on certain alternative UC management support systems, and many were impacted by anxiety/stress.

Knowledge mapping of COVID-19 and autoimmune diseases: a visual and bibliometric analysis

BACKGROUND

Many studies have shown an association between COVID-19 and autoimmune diseases (ADs). Studies on COVID-19 and ADs have also increased significantly, but there is no bibliometric analysis to summarize the association between COVID-19 and ADs. The purpose of this study was to perform a bibliometric and visual analysis of published studies related to COVID-19 and ADs.

METHODS

Based on the Web of Science Core Collection SCI-Expanded database, we utilize Excel 2019 and visualization analysis tools Co-Occurrence13.2 (COOC13.2), VOSviewer, CiteSpace, and HistCite for analysis.

RESULTS

A total of 1736 related kinds of papers were included, and the number of papers presented an overall increasing trend. The country/region with the most publications is the USA, the institution is the Harvard Medical School, the author is Yehuda Shoenfeld from Israel, and the journal is Frontiers in Immunology. Research hotspots include immune responses (such as cytokines storm), multisystem ADs (such as systemic lupus erythematosus, rheumatoid arthritis, and multiple sclerosis), treatment modalities (such as hydroxychloroquine, rituximab), vaccination and autoimmune mechanisms (such as autoantibodies, molecular mimicry). The future research direction may be the mechanisms and treatment ideas of the association between ADs and COVID-19 (such as NF-κB, hyperinflammation, antiphospholipid antibodies, neutrophil extracellular traps, granulocyte-macrophage colony-stimulating factor), other cross-diseases of COVID-19 and ADs (such as inflammatory bowel disease, chronic mucocutaneous candidiasis, acute respiratory distress syndrome).

CONCLUSION

The growth rate of publications regarding ADs and COVID-19 has risen sharply. Our research results can help researchers grasp the current status of ADs and COVID-19 research and find new research directions in the future.

Telemedicine in inflammatory bowel diseases: A new brick in the medicine of the future?

Inflammatory bowel disease (IBD) is a chronic digestive disease that requires continuous monitoring by healthcare professionals to determine the appropriate therapy and monitor short-term and long-term complications. The progressive development of information technology has enabled healthcare personnel to deliver care services to patients remotely. Therefore, various applications of telemedicine in IBD management have evolved, including telemonitoring, teleconsulting, teleducation, telenursing, telenutrition, and telepathology. While evidence has been provided for some telemedicine applications, targeted studies are still required. This review summarises the major studies that have evaluated telemedicine and its application in the management of IBD.

Managing IBD in the COVID-19 era

Over the last 2 years the lives of millions have changed because of the emergence of Coronavirus disease 2019 (COVID-19). Patients living with inflammatory bowel disease (IBD) represent a sizable population with their own sets of challenges to providers in the wake of so much uncertainty. The Centers for Disease Control considers immunocompromised individuals at higher risk of infection and complications from COVID-19. Early in the pandemic, the specific risks for IBD patients were unclear as guidance was based on expert opinion regarding the management of IBD during a COVID-19 era. Fortunately, after considerable work in the field, the overwhelming evidence suggests that IBD patients as a whole do not appear to be at increased risk for more severe disease from COVID-19. Certain risk factors such as age, steroids, comorbidities, combination immunomodulatory therapy, and IBD disease activity have been associated with worse outcomes. Most IBD medications are low risk, with the exception of immunomodulator monotherapy and combination therapy with thiopurine and anti-TNF. Vaccination remains safe and effective for all IBD patients, although additional booster doses may be necessary, particularly in patients taking anti-TNF agents.

A bibliometric analysis of inflammatory bowel disease and COVID-19 researches

Background

Patients with inflammatory bowel disease (IBD) often require immunosuppressive therapy and are hence susceptible to various opportunistic viral and bacterial infections. In this regard, many studies on IBD and COVID-19 have been conducted. However, no bibliometric analysis has been performed. This study provides a general overview of IBD and COVID-19.

Methods

Publications about IBD and COVID-19 from 2020 to 2022 were retrieved from the Web of Science Core Collection (WoSCC) database. Bibliometric analysis was performed using VOSviewer, CiteSpace, and HistCite.

Results

A total of 396 publications were retrieved and considered in this study. The maximum number of publications were from the United States, Italy, and England, and the contributions of these countries were significant. Kappelman ranked first in article citations. The Icahn School of Medicine at Mount Sinai and Inflammatory Bowel Diseases were the most prolific affiliation and journal, respectively. The most influential research topics were "management", "impact", "vaccination", and "receptor". The following keywords represented research frontiers: "depression", "the quality of life of IBD patients", "infliximab", "COVID-19 vaccine", and "second vaccination".

Conclusions

Over the past 3 years, most studies on IBD and COVID-19 have focused on clinical research. In particular, topics such as "depression", "the quality of life of IBD patients", "infliximab", "COVID-19 vaccine", and "second vaccination" were noted to have received much attention recently. Future research should focus on our understanding of the immune response to COVID-19 vaccination in biologically treated patients, the psychological impact of COVID-19, IBD management guidelines, and the long-term impact of COVID-19 in IBD patients. This study will provide researchers with a better understanding of research trends on IBD during COVID-19.

[Inflammatory bowel disease during the COVID-19 pandemic: manifestations and management]

The COVID-19 pandemic is significantly affecting the lives of patients with inflammatory bowel disease (IBD). Those affected and their relatives have numerous questions about the risk of the disease, the course of a possible SARS-CoV-2 infection or the influence of CED-specific therapy on these. Many IBD patients also have additional questions about the safety and effectiveness of a vaccination against SARS-CoV-2. The aim of this review is to summarize the latest findings on COVID-19 and IBD, but also to discuss vaccine response (humoral/cellular), the influence of ongoing therapy on the vaccine response as well as the frequency of side effects and the importance of booster immunizations and to create an evidence-based basis for discussion with patients.

Association between caregiver ability and quality of life for people with inflammatory bowel disease: The mediation effect of positive feelings of caregivers

Inflammatory bowel disease (IBD) is an incurable digestive disease. Since patients have to live with it, improving patients' quality of life is important. Caregiver's positive feelings and closeness may have a positive effect on patients' quality of life. We hypothesized that caregiver's positive feeling affected patient's quality of life through caregiver's caring ability, and closeness might be the upstream of this chain. In this study, we conducted a single-center cross-sectional survey by questionnaire in China to tested the hypothesis. A total of 181 patient-caregiver pairs were included. The short version of the IBD questionnaire (SIBDQ), the twelve-item short-form health survey (SF-12), the positive aspects of caregiving (PAC) and Capacity Scale of caregivers were used to collect data. All the data were collected in one interview. Spearman correlation and Bootstrap method were used to analyze the data. Mediation analysis results indicated that caregiver's caring ability mediated the association between caregiver's positive feelings and patients' quality of life (p < 0.01), which explained 34.1% of the total variation of patients' quality of life. Mediation analysis results also revealed that patient-evaluated or caregiver-evaluated closeness had a positive effect on patients' quality of life through caregiver's positive feeling and caregiver's caring ability (p < 0.05), which explained 2.1 and 2.3% of the variation of patients' quality of life. Caregiver's positive feelings were related to caregivers' quality of life (p < 0.01), but there was no significant association between caregivers' ability and caregivers' quality of life. In summary, our model revealed that caregiver's positive feeling affected patients' quality of life through caregiver's caring ability.

Impact of COVID-19 Pandemic on the Quality of Life of IBD Patients

Background and Objectives: The COVID-19 pandemic has had a considerable impact on inflammatory bowel disease (IBD) patients by limiting their access to medical services due to restrictions and the reorganization of the healthcare systems, which affects their quality of life (QoL). We aimed to assess the impact of the COVID-19 pandemic on the QoL of patients with IBD. Materials and Methods: We conducted a descriptive observational study, which included 90 adult patients diagnosed with IBD. The study sample consisted of two subgroups: a retrospective-pre-pandemic group (group A) and a prospective-pandemic group (group B). Group A included 45 IBD patients who were evaluated in 2018. Group B included 45 patients with confirmed diagnosis of IBD, evaluated between June and December 2021—the period of the COVID-19 pandemic (prospective), consecutively recruited. All the patients filled in a QoL assessment questionnaire—IBDQ-32. Subsequently, the two samples were comparatively assessed. Results: The average values of the IBDQ scores were significantly lower in 2021 compared to those recorded in 2018: 145.56 vs. 128.3 (p < 0.05). We also we found significant differences between the subscores: IBDQ1 (p = 0.043), IBDQ2 (p = 0.034), IBDQ3 (p = 0.045), IBDQ4 (p = 0.025). Conclusions: IBDQ scores were significantly lower in 2021 compared to 2018 (p < 0.05), showing that during the COVID-19 pandemic, patients with IBD had a more influenced QoL.
