Inflammatory Bowel Disease Management During the Coronavirus-19 Outbreak: A Survey From the European Crohn's and Colitis Organization

Increased Hospitalization for IBD Patients Seen in the ER During the COVID-19 Pandemic

Background

During the COVID-19 pandemic, the focus of many health care systems shifted in order to prioritize and allocate resources toward treating those affected by COVID-19. What this has meant for other patient populations remains unclear. We aimed to determine if there have been changes to acute care access for patients with inflammatory bowel disease (IBD) during the COVID-19 pandemic.

Methods

A retrospective cohort study was performed in IBD patients seen during (March 1, 2020 to August 31, 2020) and before (March 1, 2019 to August 31, 2019) the COVID-19 pandemic. IBD-related emergency room (ER) access, hospitalization, inpatient care and follow-up and post-discharge ER access were assessed.

Results

A total of 1229 participants were included. A higher proportion of patients accessed ER during the pandemic (44.6% versus 37.2%, P = 0.0097). A higher proportion of hospitalizations resulted from IBD-related ER visits during the pandemic period (41.6% versus 32.4%, OR = 1.48, 95% CI = 1.14 to 1.94, P = 0.0047), though length of stay was shorter (7.13 ± 8.95 days versus 10.11 ± 17.19 days, P = 0.015) and use of rescue infliximab was less. No change was seen in inpatient surgical intervention. Despite similar proportions of follow-up appointments post-hospital discharge (pre-pandemic, 77.9% versus pandemic, 78.3%), more ER visits occurred in the first 30 days following hospitalization for patients in the pandemic cohort (24.4% versus 11.1%, P = 0.0015).

Conclusion

These data highlight the need for ER services and hospitalization amongst IBD patients during the COVID-19 pandemic. This suggests that a return to pre-pandemic IBD care infrastructure is needed to mitigate the need for acute care access.

Perception of COVID-19 Pandemic Among IBD Clinicians and IBD Surgeons in Black Sea Region: A Cross-Sectional Questionnaire Study

BACKGROUND

Since December 2019, the COVID-19 pandemic has created an increasing challenge in managing inflammatory bowel dis- ease patients both medically and surgically. Although several international and national medical/surgical associations published guide- lines in this area, there is still a huge difference between daily practices and these guidelines, especially depending on regional practices and governmental policies. Therefore, we aimed to investigate and define gastroenterologists' and surgeons' fear of COVID-19 and how they have managed inflammatory bowel disease patients during this pandemic in the Black Sea region.

METHODS

A 20-question survey was administered to 70 gastroenterology specialists and 80 general surgeons who are mainly focused on the management of inflammatory bowel disease in 5 countries in the Black Sea region.

RESULTS

The majority of respondents (81.3%) mentioned that they have concerns that their inflammatory bowel disease patients were at risk of contracting COVID-19. In addition, the majority of respondents (80.3%) believed that inflammatory bowel disease itself, inde- pendent of medications, might increase the risk of contracting COVID-19. The majority of gastroenterologists told that they did not stop inflammatory bowel disease medications due to the COVID-19 pandemic unless patients had COVID-19 disease. Surgeons overwhelm- ingly reached a consensus on how to test patients for COVID-19 perioperatively and came to a conclusion on which of the patients can- not wait to be operated. Both gastroenterologists and general surgeons, usually have similar perceptions.

CONCLUSION

Despite the increasing number of definitive studies, it seems that there are still regional differences in the perception of COVID-19 and inflammatory bowel disease patient care during the pandemic.

Impact of COVID-19 pandemic on pediatric endoscopy: A multicenter study on behalf of the SIGENP Endoscopy Working Group

BACKGROUND

Aim of the present report was to investigate the repercussions of COVID-19 pandemic on the procedural volumes and on the main indications of pediatric digestive endoscopy in Italy.

METHODS

An online survey was distributed at the beginning of December 2020 to Italian digestive endoscopy centers. Data were collected comparing two selected time intervals: the first from 1st of February 2019 to 30th June 2019 and the second from 1st February 2020 to 30th June 2020.

RESULTS

Responses to the survey came from 24 pediatric endoscopy Units. Globally, a reduction of 37.2% was observed between 2019 and 2020 periods with a significant decrease in median number of procedures (111 vs 57, p < 0.001). Both the median number of procedures performed for new diagnoses and those for follow-up purposes significantly decreased in 2020 (63 vs 36, p < 0.001 and 42 vs 21, p< 0.001, respectively). We reported a drastic reduction of procedures performed for suspected Celiac Disease and Functional Gastrointestinal Disorders (55.1% and 58.0%, respectively). Diagnostic endoscopies for suspected IBD decreased of 15.5%, whereas procedures for Mucosal Healing (MH) assessment reduced of 48.3%.

CONCLUSIONS

Our study provides real-world data outlining the meaningful impact of COVID-19 on pediatric endoscopy practice in Italy.

Inflammatory Bowel Disease and COVID-19: How Have Patients Coped So Far?

OBJECTIVE

Knowledge about SARS-CoV2 and coronavirus disease 2019 (COVID-19) is growing fast. Massive changes in the health care system imposed by the COVID-19 pandemic clearly impact the overall quality of medical care. In this survey, we aim to explore experiences and concerns of patients with inflammatory bowel disease (IBD) regarding the current pandemic.

METHODS

A 40-item web-based questionnaire on disease-related experiences and concerns during the COVID-19 pandemic was made available to patients with IBD from 28 April 2020 to 31 July 2020.

RESULTS

An increased risk of SARS-CoV2 infection was a concern for 56.7% of the 1199 patients (aged 41.3±12.8, women 77%, Crohn's disease 58.8%, ulcerative colitis 38.5%); 61.7% feared an increased risk of severe disease course of COVID-19. Effective preventive measures in either outpatient practices or hospitals were observed by 84.7% of the patients. Appointments with an IBD specialist were canceled in 38.7%, frequently on the patients' initiative. Telecommunication visits were considered an acceptable alternative to personal visits by 71.0%. Medication was reduced or paused in 6.9% because of the pandemic. A swab (SARS-CoV2-PCR) was done in 13.2% of the patients; only 3 patients (0.25%) were tested positive.

CONCLUSION

The COVID-19 pandemic is a major concern of patients with IBD. However, the cumulative prevalence in our cohort is low. Patients at risk should be identified and counseled individually. When required because of the local COVID-19 situation, telecommunication visits and liberal prescription policies are advisable to reduce in-person contacts, while ensuring continuous therapy and maintaining communication with patients.

Efficacy, Safety and Future Perspectives of JAK Inhibitors in the IBD Treatment

Although development of biologics has importantly improved the effectiveness in inducing and maintaining remission in inflammatory bowel disease (IBD), biologic therapies still have several limitations. Effective, low-cost drug therapy with good safety profile and compliance is therefore a substantial unmet medical need. A promising target for IBD treatment strategies are Janus kinase (JAK) inhibitors, which are small molecules that interact with cytokines implicated in pathogenesis of IBD. In contrast to monoclonal antibodies, which are able to block a single cytokine, JAK inhibitors have the potential to affect multiple cytokine-dependent immune pathways, which may improve the therapeutic response in some IBD patients. Tofacitinib, inhibiting signaling via different types of JAKs, has been already approved for ulcerative colitis, and several other small-molecule are still under investigation. However, one of the main concerns about using JAK inhibitors is the risk of thromboembolic events. Moreover, patients with COVID-19 appear to have an increased susceptibility for immunothrombosis. Therefore, thrombotic complications may become a serious limitation in the use of JAK inhibitors in the SARS-CoV-2 pandemic. As many questions about safety and efficacy of small molecules still remain unclear, in our review we present the current data regarding approved JAK inhibitors, as well as those in clinical development for the treatment of IBD.

Why Do Immunosuppressed Patients with Inflammatory Bowel Disease Not Seem to Be at a Higher Risk of COVID-19?

The COVID-19 pandemic has created a public health emergency. In this context, there are major concerns for patients with inflammatory bowel disease (IBD), particularly for those treated with immunomodulators, biologics, and Janus Kinase inhibitors. Infection susceptibility is, in fact, one of the reported risks for immunotherapy drugs. This review provides the existing evidence from worldwide case series describing: (a) the risk for the SARS-CoV-2 infection and (b) the risk of a severe infection outcome in patients with IBD treated with immunotherapy. Further, the review discusses the potential mechanisms underlying why this group of patients with IBD might be protected from contracting the infection and from a worse disease. From the available data, it appears that these patients should have an enhanced adherence to the recommended preventive measures, suggesting a role in reducing their risk of infection. Furthermore, the immunotherapy may dampen the cytokine storm and inflammation associated with COVID-19. The results of this review seem to confirm that patients with IBD receiving immunomodulators, biologics, or Janus Kinase inhibitors do not have an increased risk of contracting SARS-CoV-2 infection or develop a more severe COVID-19. According to the current evidence, it is advisable to maintain immunotherapy, apart from corticosteroids, in patients with IBD in order to avoid relapse. This review reports only on the cases of patients who tested positive for SARS-CoV-2 by RT-PCR of a nasopharyngeal swab sample. This is a limitation and a more accurate epidemiological picture of the infection will be obtained only via the expanded use of antibody tests.

[KASID Guidance for Clinical Practice Management of Adult Inflammatory Bowel Disease during the COVID-19 Pandemic: Expert Consensus Statement]

The coronavirus disease 2019 (COVID-19) pandemic has reduced the ability to prevent or control chronic disease due to the concerns about safety in accessing health care. Inflammatory bowel disease (IBD) is a chronic condition requiring long- term sustained treatment, which is difficult in the current panedemic situation. The Korean Association for the Study of Intestinal Diseases (KASID) has developed an expert consensus statement on the clinical practice management of adult inflammatory bowel disease during the COVID-19 pandemic. This expert consensus statement is based on guidelines and clinical reports from several countries around the world. It provides recommendations to deal with the risk of COVID-19 and medication use in IBD patients with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection and emphasizes the importance of right treatment approach to avoid worsening of the disease condition in IBD patients.

Turkish IBD Organization's Position Statement on Inflammatory Bowel Disease Management Recommendations During COVID-19 Pandemic

The COVID-19 pandemic, caused by the novel severe acute respiratory syndrome coronavirus 2, has resulted in high mortality and morbidity worldwide and is still a growing problem. Inflammatory bowel disease (IBD) is a chronic inflammatory disease for which a substantial number of patients are treated with immunosuppressive medications, either occasionally or long-term. Despite the accumulating evidence, there is still a lack of knowledge about the impact of COVID-19 on IBD patients, especially those who are under immunosuppressive treatment. Moreover, following the emergence of several COVID vaccines, there are concerns regarding vaccine effectiveness and possible side effects in such patients. In this context, we tried to briefly summarize the accumulating evidence and recommendations for the management of IBD in the context of the COVID-19 pandemic.

Hospitalisation for Drug Infusion Did Not Increase Levels of Anxiety and the Risk of Disease Relapse in Patients with Inflammatory Bowel Disease during COVID-19 Outbreak

During the coronavirus disease 2019 (COVID-19) pandemic, immunomodulatory therapies and hospital admission were suspected to increase the risk of infection. Nevertheless, patients with inflammatory bowel diseases (IBD) treated with intravenous (i.v.) biologics had to move to hospitals for drug infusion. We investigated the impact of hospitalisation in patients with IBD. We conducted a survey including consecutive IBD patients initially in clinical and biochemical remission treated with biologics at the end of the first lockdown period. Patients underwent the normally scheduled clinical visits, performed at hospital for i.v.-treated patients or at home for patients treated with s.c. drugs. We administered to all patients the Hospital Anxiety and Depression Scale (HADS) questionnaire and other 12 questions, specifically related to COVID-19 and its implications. A total of 189 IBD patients were recruited, 112 (59.3%) treated with i.v. drugs and 77 (40.7%) with s.c. ones. No relapses were recorded in either group (hospitalized vs. non-hospitalized, p = ns), as well as which, COVID-19 infections were not demonstrated in patients in contact with people with suspected symptoms or directly experiencing them. The total HADS score obtained by the sum of all items was also almost identical between groups (37.1 ± 2.8 vs. 37.2 ± 2.8; p = 0.98). In patients treated with i.v. drugs receiving a televisit (n = 17), the rate of satisfaction with telemedicine (58.8%) was significantly lower compared with those treated with s.c. drugs (94.8%; p < 0.0005). Our results suggest that hospitalisation during the COVID-19 outbreak does not increase the risk of COVID-19 infection as well as the risk of IBD relapse; moreover, the similar levels of anxiety in both groups could confirm that there is no need to convert patients from i.v. to s.c. therapy.

Perceptions and Behaviors of Patients with Inflammatory Bowel Disease during the COVID-19 Crisis

Background/Aims

This study aimed to investigate the perceptions and behaviors of patients with inflammatory bowel disease (IBD) during the early coronavirus disease 2019 (COVID-19) pandemic in the major epidemic area in Korea.

Methods

Between April and May 2020, a cross-sectional survey was performed at two tertiary hospitals in Daegu, South Korea, on patients’ experiences, coping strategies and perceptions.

Results

Most of the 544 patients participating in the survey strictly adhered to personal protection guidance against COVID-19. In the early COVID-19 crisis, many patients canceled or postponed hospital visits (57.5%) and rescheduled biologics administrations (26.4%). Although 13.6% utilized telemedicine, the frequency of individuals leaving their homes remained unchanged. Although 50.4% were concerned about their susceptibility to COVID-19, 72.2% adhered to their treatment for IBD. In patients taking biologics or Janus kinase inhibitors, 86.8% disagreed that they should discontinue their medication as a preventative measure against COVID-19, but 21.9% actually discontinued their medications. Of those with discordance between the perception of IBD drug adherence and active behaviors, 5.4% of all and 39.4% of biologics or Janus kinase inhibitors withheld drugs specifically due to fear of COVID-19. Only 7% of all patients discussed drug safety with their physicians. The level of concern for COVID-19 depended on the type of drug used.

Conclusions

Patients with IBD showed concerns about the increased risk of COVID-19 due to IBD or their medications, and a considerable number of patients withheld their medications without consulting medical staff. Enhanced active communications with patients with IBD and appropriate health-related education should be provided.

Impact of the COVID-19 pandemic on inflammatory bowel disease patients: A review of the current evidence

Since the initial coronavirus disease 2019 (COVID-19) outbreak in China in December 2019, the infection has now become the biggest medical issue of modern medicine. Two major contributors that amplified the impact of the disease and subsequently increased the burden on health care systems were high mortality among patients with multiple co-morbidities and overcapacity of intensive care units. Within the gastroenterology-related community, particular concern was raised with respect to patients with inflammatory bowel disease (IBD), as those patients are prone to opportunistic infections mainly owing to their immunosuppressive-based therapies. Hence, we sought to summarize current knowledge regarding COVID-19 infection in patients with IBD. Overall, it seems that IBD is not a comorbidity that poses an increased risk for COVID-19 acquisition, except in patients treated with 5-aminosalicylates. Furthermore, outcomes of the infected patients are largely dependent on therapeutic modality by which they are treated, as some worsen the clinical course of COVID-19 infection, whereas others seem to dampen the detrimental effects of COVID-19. Finally, we discussed the present and the future impact of COVID-19 pandemic and concomitantly increased health care burden on IBD-management.

Subtotal colectomy for refractory ulcerative colitis with COVID-19 infection; a first case report in Japan

We report a 60-year-old male who was transferred to our hospital for the operation because of refractory ulcerative colitis (UC). He was diagnosed to be infected with COVID-19 for SARS-CoV-2 PCR test positive at the time of transfer. We determined emergency operation because his general condition was poor such as malnutrition and ADL decline due to exacerbation of UC and air embolization by central venous catheter removal. He underwent subtotal colectomy with a sigmoid mucous fistula and ileostomy. He was well postoperatively. This is a first case report in Japan who underwent an operation for UC with COVID-19 infection.

The complex relationship between viruses and inflammatory bowel disease - review and practical advices for the daily clinical decision-making during the SARS-CoV-2 pandemic

The coronavirus disease 2019 (COVID-19) outbreak emerged in December 2019 in China and rapidly spread worldwide. Inflammatory bowel disease (IBD) patients are likely to be more susceptible to viral infections, and this is significantly influenced by the type of therapy they receive. Thus, issues specifically concerning the medical treatment of IBD patients were shortly addressed at the beginning of the pandemic. However, recently available data on the occurrence and outcome of SARS-CoV-2 infection in IBD patients does not address the concerns raised at the beginning of the pandemic. Growing evidence and the rapid changes happening over the past few weeks have helped elucidate the current situation, contribute to our understanding of the disease, and many previously raised questions could now be answered. We hereby summarise available evidence regarding viral infections and IBD, focusing on SARS-CoV infections, and we provide practical recommendations related to patient management during the COVID-19 pandemic era.

Humoral response to COVID-19 infection in immunosuppressed patients with inflammatory bowel disease

The course of coronavirus 19 (COVID-19) might be determined by certain comorbidities (e.g. diabetes, hypertension and other cardiovascular diseases) and advanced age. Because the impact of immunosuppression on disease severity is not entirely clear, management of patients under immunosuppressive treatment remains controversial. Six cases of inflammatory bowel disease (IBD) patients with COVID-19 on immunosuppressive medication are presented. The aim of this study was to describe patients' clinical manifestation and chronologic development of virus-specific antibodies of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection before and after restart with immunosuppressive/biological therapy as an indicator for a specific immune response. All patients were tested for the presence of SARS-CoV-2-RNA with PCR, were in clinical remission prior to COVID-19 and only one patient continued his immunosuppressive treatment during the COVID-19 infection. Initial symptoms of COVID-19 were pyrexia, diarrhea, cephalea, and dysgeusia and anosmia. No patient needed admission to hospital or ICU. The SARS-CoV-2 antibody development was described to be late in three of the six patients. Late antibody development seems to be more frequent in older patients and in patients with combined immunosuppressive treatment. In this scenario, SARS-CoV-2 antibody testing could be useful prior to restarting immunosuppressive therapy.

Impact of COVID-19 pandemic on the management of paediatric inflammatory bowel disease: An Italian multicentre study on behalf of the SIGENP IBD Group

BACKGROUND

IBD management has been significantly affected during the COVID-19 lockdown with potential clinical issues.

AIMS

The aim of this study was to analyse the impact of COVID-19 pandemic on the Italian paediatric IBD cohort.

METHODS

This was a multicentre, retrospective, cohort investigation including 21 different Italian IBD referral centres. An electronic data collection was performed among the participating centres including: clinical characteristics of IBD patients, number of COVID-19 cases and clinical outcomes, disease management during the lockdown and the previous 9 weeks.

RESULTS

2291 children affected by IBD were enrolled. We experienced a significant reduction of the hospital admissions [604/2291 (26.3%) vs 1281/2291 (55.9%); p < 0.001]. More specifically, we observed a reduction of hospitalizations for new diagnosis (from n = 44 to n = 27) and endoscopic re-evaluations (from n = 46 to n = 8). Hospitalization for relapses and surgical procedures remained substantially unchanged. Biologic infusions did not significantly vary [393/2291 (17.1%) vs 368/2291 (16%); p = 0.3]. Telemedicine services for children with IBD were activated in 52.3% of the centres. In 42/2291(1.8%) children immunosuppressive therapies were adapted due to the concurrent COVID-19 pandemic.

CONCLUSION

Due to the several limitations of the lockdown, cares for children with IBD have been kept to minimal standards, giving priorities to the urgencies and to biologics' infusions and implementing telemedicine services.

Management of paediatric IBD after the peak of COVID-19 pandemic in Italy: A position paper on behalf of the SIGENP IBD working group

Coronavirus Disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2, spreading in Italy during the first months of 2020, abruptly changed the way of practicing medicine in this country. As a consequence of the lockdown, the diagnostic and therapeutic management of paediatric chronic conditions, such as inflammatory bowel disease (IBD) has been affected. During the peak of COVID-19 pandemic, elective visits, endoscopies and infusions have been postponed, with potential clinical and psychological impact on disease course and a high likelihood of increasing waiting lists. While slowly moving back towards normality, clinicians need to recognize the best ways to care for patients with IBD, carefully avoiding risk factors for new potential epidemic outbreaks. In this uncertain scenario until the development and spread of COVID-19 vaccine, it is necessary to continue to operate with caution. Hereby we provide useful indications for a safer and gradual restarting of routine clinical activities after COVID-19 peak in Italy.

Impact of COVID-19 on the Healthcare of Patients With Inflammatory Bowel Disease: A Comparison Between Epicenter vs. Non-epicenter Areas

Background and Aims: The COVID-19 pandemic poses a great challenge to healthcare. We aimed to investigate the impact of COVID-19 on the healthcare of patients with inflammatory bowel disease (IBD) in epicenter and non-epicenter areas.

Methods: Patients with IBD from Hubei province (the epicenter of COVID-19) and Guangdong province (a non-epicenter area), China were surveyed during the pandemic. The questionnaire included change of medications (steroids, immunomodulators, and biologics), procedures (lab tests, endoscopy, and elective surgery), and healthcare mode (standard healthcare vs. telemedicine) during 1 month before and after the outbreak of COVID-19.

Results: In total, 324 IBD patients from Guangdong province (non-epicenter) and 149 from Hubei province (epicenter) completed the questionnaire with comparable demographic characteristics. Compared to patients in Guangdong province (non-epicenter), significantly more patients in Hubei (epicenter) had delayed lab tests/endoscopy procedures [61.1% (91/149) vs. 25.3% (82/324), p < 0.001], drug withdrawal [28.6% (43/149) vs. 9.3% (30/324), p < 0.001], delayed biologics infusions [60.4% (90/149) vs. 19.1% (62/324), p < 0.001], and postponed elective surgery [16.1% (24/149) vs. 3.7% (12/324), p < 0.001]. There was an increased use of telemedicine after the outbreak compared to before the outbreak in Hubei province [38.9% (58/149) vs. 15.4% (23/149), p < 0.001], while such a significant increase was not observed in Guangdong province [21.9% (71/324) vs. 18.8% (61/324), p = 0.38]. Approximately two-thirds of IBD patients from both sites agreed that telemedicine should be increasingly used in future medical care.

Conclusions: Our patient-based survey study in a real-world setting showed that COVID-19 resulted in a great impact on the healthcare of patients with IBD, and such an impact was more obvious in the epicenter compared to the non-epicenter area of COVID-19. Telemedicine offers a good solution to counteract the challenges in an unprecedented situation such as COVID-19.

Systematic Review on Inflammatory Bowel Disease Patients With Coronavirus Disease 2019: It Is Time to Take Stock

BACKGROUND & AIMS

Data on the clinical characteristics of patients with inflammatory bowel diseases (IBDs) with coronavirus disease 2019 (COVID-19) are scarce. The aim of our systematic review was to investigate symptoms and diagnostic-therapeutic management of IBD patients with COVID-19.

METHODS

We searched PubMed, Embase, Web of Science, and MedRxiv up to July 29, 2020, to identify all studies reporting clinical information on adult and pediatric IBD patients with confirmed COVID-19.

RESULTS

Twenty-three studies met our inclusion criteria, including 243,760 IBD patients. COVID-19 was diagnosed in 1028 patients (509 with Crohn's disease [49.5%], 428 with ulcerative colitis [41.6%], 49 with indeterminate colitis [4.8%], and 42 with missing data [4.1%]), accounting for a cumulative prevalence of 0.4%. Viral infection occurred more frequently in males than in females (56.5% vs 39.7%), and the mean age ranged from 14 to 85 years. The most common symptoms were fever (48.3%), cough (46.5%), and diarrhea (20.5%), and a COVID-19 diagnosis was achieved mainly through polymerase chain reaction analysis of nasopharyngeal swabs (94.4%) and chest computed tomography scans (38.9%). Hydroxychloroquine (23.9%), lopinavir/ritonavir (8.2%), steroids (3.2%), and antibiotics (3.1%) were the most used drugs. Overall, approximately a third of patients were hospitalized (30.6%), and 11.4% of them required admission to the intensive care unit. In total, 29 COVID-19-related deaths were reported (3.8%), and increasing age and the presence of comorbidities were recognized as risk factors for COVID-19 and negative outcomes.

CONCLUSIONS

Diarrhea occurs more frequently in IBD patients with COVID-19 than in the non-IBD population. Further studies are needed to define the optimal diagnostic-therapeutic approach in IBD patients with COVID-19.

Intestinal Receptor of SARS-CoV-2 in Inflamed IBD Tissue Seems Downregulated by HNF4A in Ileum and Upregulated by Interferon Regulating Factors in Colon

BACKGROUND

Patients with inflammatory bowel disease [IBD] are considered immunosuppressed, but do not seem more vulnerable for COVID-19. Nevertheless, intestinal inflammation has shown to be an important risk factor for SARS-CoV-2 infection and prognosis. Therefore, we investigated the role of intestinal inflammation on the viral intestinal entry mechanisms, including ACE2, in IBD.

METHODS

We collected inflamed and uninflamed mucosal biopsies from Crohn's disease [CD] [n = 193] and ulcerative colitis [UC] [n = 158] patients, and from 51 matched non-IBD controls for RNA sequencing, differential gene expression, and co-expression analysis. Organoids from UC patients were subjected to an inflammatory mix and processed for RNA sequencing. Transmural ileal biopsies were processed for single-cell [sc] sequencing. Publicly available colonic sc-RNA sequencing data, and microarrays from tissue pre/post anti-tumour necrosis factor [TNF] therapy, were analysed.

RESULTS

In inflamed CD ileum, ACE2 was significantly decreased compared with control ileum [p = 4.6E-07], whereas colonic ACE2 was higher in inflamed colon of CD/UC compared with control [p = 8.3E-03; p = 1.9E-03]. Sc-RNA sequencing confirmed this ACE2 dysregulation and exclusive epithelial ACE2 expression. Network analyses highlighted HNF4A as key regulator of ileal ACE2, and pro-inflammatory cytokines and interferon regulating factors regulated colonic ACE2. Inflammatory stimuli upregulated ACE2 in UC organoids [p = 1.7E-02], but not in non-IBD controls [p = 9.1E-01]. Anti-TNF therapy restored colonic ACE2 regulation in responders.

CONCLUSIONS

Intestinal inflammation alters SARS-CoV-2 coreceptors in the intestine, with opposing dysregulations in ileum and colon. HNF4A, an IBD susceptibility gene, seems an important upstream regulator of ACE2 in ileum, whereas interferon signalling might dominate in colon.

React, reset and restore: Adaptation of a large inflammatory bowel disease service during COVID-19 pandemic

INTRODUCTION

Healthcare organisations have had to make adaptations to reduce the impact of the Coronavirus 2019 (COVID-19) pandemic. This has necessitated urgent reconfiguration within inflammatory bowel disease (IBD) services to ensure safety of patients and staff and seamless continuity of care provision.

AIM

To describe the adaptations made by a large inflammatory bowel disease service, caring for over 3,500 IBD patients, in response to the COVID-19 pandemic.

METHODS

A diary record of responses to the pandemic were logged, and meeting minutes were reviewed. Data were recorded from IBD advice lines, multidisciplinary team (MDT) meeting minutes, infusion unit attendances, and electronic referral systems for the 8-week period from 9 March 2020 until 2 May 2020. Descriptive analysis was performed.

RESULTS

The IBD service at Hull University Teaching Hospitals NHS Trust (IBD Hull) instituted rapid structural and functional changes to the service. Outpatient services were suspended and substituted by virtual consultations, and inpatient services were reduced and moved to ambulatory care where possible. The delivery of biologic and immunomodulatory therapies was significantly modified to ensure patient and staff safety. There was a substantial increase in IBD advice line calls.

CONCLUSION

The rapidly evolving COVID-19 pandemic required a prompt response, regular reassessment and planning, and continues to do so. We share our experience in of the successful adaptations made to our IBD service.

Worldwide Management of Inflammatory Bowel Disease During the COVID-19 Pandemic: An International Survey

BACKGROUND AND AIMS

Persons with inflammatory bowel disease (IBD) may be particularly vulnerable to COVID-19 either because of their underlying disease or its management. Guidance has been presented on the management of persons with IBD in the time of this pandemic by different groups. We aimed to determine how gastroenterologists around the world were approaching the management of IBD.

METHODS

Members of the World Gastroenterology Organization (WGO) IBD Task Force contacted colleagues in countries largely beyond North America and Europe, inviting them to review the WGO website for IBD and COVID-19 introduction, with links to guideline documents, and then to respond to 9 ancillary open-ended management questions.

RESULTS

Fifty-two gastroenterologists from 33 countries across 6 continents completed the survey (April 14 to May 16, 2020). They were all adhering for the most part to published guidelines on IBD management in the COVID-19 era. Some differences and reductions in services related to access, and some related to approach within their communities in terms of limiting virus spread. In particular, most gastroenterologists reduced in-person clinics (43 of 52), limited steroid use (47 of 51), limited elective endoscopy (45 of 52), and limited elective surgeries (48 of 51). If a patient was diagnosed with COVID-19, immunomodulatory therapy was mostly held.

CONCLUSIONS

In most countries, the COVID-19 pandemic significantly altered the approach to persons with IBD. The few exceptions were mostly based on low burden of COVID-19 in individual communities. Regardless of resources or health care systems, gastroenterologists around the world took a similar approach to the management of IBD.

COVID-19 and Inflammatory Bowel Disease: Patient Knowledge and Perceptions in a Single Center Survey

Background and objectives: Spreading of SARS-CoV-2 infection from China to countries with a higher prevalence of inflammatory bowel disease (IBD) has generated concern among gastroenterologists and patients. The aim of this survey is to evaluate knowledge about clinical importance of COVID-19, disease management, prevention measures, and anxiety level during pandemic among patients with IBD. Material and methods: From 15th March to 15th April 2020, a questionnaire survey was administered to 200 patients with IBD by email or phone application. The questionnaire consisted of five sections: (1) anthropometric, demographic and clinical characteristics, (2) knowledge about clinical importance of COVID-19, (3) IBD management, (4) prevention measures, (5) anxiety level during pandemic. Results: One hundred forty two questionnaires were completed. Ninety-seven patients (68.3%) were males with a mean age of 46 years (SD 13; range 17-76). Fifty-four individuals (38%) were affected by Crohn disease and 88 (62%) by Ulcerative Colitis. Most patients reported high knowledge about clinical importance of COVID-19 (80%), IBD management (72%), and prevention measures (97%). Sixty-two percent of them showed moderate-high level of anxiety. High education level was independently associated with high knowledge about clinical importance of COVID-19 (odds ratio [OR] 5, 95% confidence interval [CI] 1.49-16.6, p = 0.009) and older age (OR 1, 95%, CI 1.01-1.1, p = 0.01), while the receipt of e-format educational material with low knowledge about clinical importance of COVID-19 (OR 3, 95%, CI 1.08-9.3, p = 0.03). Displaying an active disease appeared to be independently associated with low knowledge of IBD management (OR 5.8, 95% CI 1.4-22.8, p = 0.01) and no variables other than an older age was independently associated with higher level of anxiety (OR 1.04, 95% CI 1.009-1.09, p = 0.01). Conclusions: High educational level and aging promote knowledge about clinical importance of COVID-19, while e-format educational material does not. Taken together with findings that an active disease status compromises knowledge of IBD management and the high level of anxiety related to increasing age, these data suggest the need of further supporting patient-oriented strategies in IBD during Covid-19 pandemic.

Inflammatory Bowel Disease Management During the COVID-19 Outbreak: The Ten Do's and Don'ts from the ECCO-COVID Taskforce

Our knowledge of COVID-19 is changing and evolving rapidly, with novel insights and recommendations, almost on a daily basis. It behooves the medical community to provide updated information on a regular basis, on best practice to facilitate optimal care of infected patients and on appropriate advice for the general population. This is particularly important in the case of patients with chronic conditions, such as inflammatory bowel disease [IBD]. In this review, we have compiled existing evidence on the impact of COVID-19 in IBD patients and provide guidance on the most appropriate care to adopt during the pandemic. Our review highlights that IBD, per se, is not a risk factor for COVID-19. However, all IBD patients with symptoms should be tested for SARS-CoV-2 and the procedures for disease management should be carefully adapted: [i] in SARS-CoV-2-positive IBD patients, medical treatments should be re-evaluated [with a particular focus on corticosteroids] always with the purpose of treating active disease and maintaining remission; [ii] non-urgent surgeries and endoscopic procedures should be postponed for all patients; [iii] online consultancy should be implemented; and [iv] hospitalization and surgery should be limited to life-threatening situations.

Safety of Drugs During Previous and Current Coronavirus Pandemics: Lessons for Inflammatory Bowel Disease

The coronavirus 2019 [COVID-19] pandemic has posed challenges in the routine care of patients with inflammatory bowel disease [IBD]. One of the key challenges is quantification of the risks of immunosuppressive and biological therapies in IBD patients during the pandemic. The similarities and differences between previous coronavirus outbreaks and the pathobiology of the infections can give useful information in understanding the risks, and perhaps potential beneficial aspects of drugs used in IBD. Although clinical, immunological and pharmacological data from the experience with previous coronavirus outbreaks cannot be automatically translated to predict the safety of IBD therapies during the COVID-19 pandemic, the signals so far from these outbreaks on IBD patients who are on immunomodulators and biologics are reassuring to patients and clinicians alike.
