Up till now, research on inflammatory bowel disease [IBD] has mainly been focused on the immune cells present in the gastrointestinal tract. However, recent insights indicate that stromal cells also play an important and significant role in IBD pathogenesis. Stromal cells in the intestines regulate both intestinal epithelial and immune cell homeostasis. Different subsets of stromal cells have been found to play a role in other inflammatory diseases [e.g. rheumatoid arthritis], and these various stromal subsets now appear to carry out also specific functions in the inflamed gut in IBD. Novel potential therapies for IBD utilize, as well as target, these pathogenic stromal cells. Injection of mesenchymal stromal cells [MSCs] into fistula tracts of Crohn's disease patients is already approved and used in clinical settings. In this review we discuss the current knowledge of the role of stromal cells in IBD pathogenesis. We further outline recent attempts to modify the stromal compartment in IBD with agents that target or replace the pathogenic stroma.

The use of corticosteroids to treat patients with inflammatory bowel disease [IBD] has been the bedrock of IBD therapeutics since the pioneering work of Truelove and Witts in the UK in the 1950s and subsequent large cohort studies in the USA and Europe. Nevertheless, although effective for induction of remission, these agents do not maintain remission and are associated with a long list of recognised side effects, including a risk of increased mortality. With the arrival of an increasing number of therapies for patients with IBD, the question arises as to whether we are using these agents appropriately in contemporary practice. This review discusses the historical background to steroid usage in IBD, and also provides a brief review of the literature on side effects of corticosteroid treatment as relevant to IBD patients. Data on licensed medications are presented with specific reference to the achievement of corticosteroid-free remission. We review available international data on the incidence of corticosteroid exposure and excess, and discuss some of the observations we and others have made concerning health care and patient-level factors associated with the risk of corticosteroid exposure, including identification of 'at-risk' populations.

The outbreak of the COVID-19 caused by coronavirus SARS-CoV2, is rapidly spreading worldwide. This is the first pandemic caused by a coronavirus in history. More than 150 000 confirmed cases worldwide are reported involving the SARS-CoV2, with more than 5000 COVID-19-related deaths on March 14, 2020. Fever, chills, cough, shortness of breath, generalised myalgia, malaise, drowsiness, diarrhoea, confusion, dyspnoea, and bilateral interstitial pneumonia are the common symptoms. No therapies are available, and the only way to contain the virus spread is to regularly and thoroughly clean one's hands with an alcohol-based hand rub or wash them with soap and water, to maintain at least 1 m [3 feet] distance from anyone who is coughing or sneezing, to avoid touching eyes, nose, and mouth, and to stay home if one feels unwell. No data are available on the risk of COVID-19 and outcomes in inflammatory bowel disease [IBD] patients. Outbreak restrictions can impact on the IBD care. We aim to give a viewpoint on how operationally to manage IBD patients and ensure quality of care in the current pandemic era.

Crohn's disease [CD] and ulcerative colitis [UC], the main inflammatory bowel diseases [IBD] in humans, are chronic, immune-inflammatory diseases, the pathogenesis of which suggests a complex interaction between environmental factors and genetic susceptibility. These disabling conditions affect millions of individuals and, together with the drugs used to treat them, can put patients at risk of developing complications and other conditions. This is particularly relevant today, as coronavirus disease [Covid-19] has rapidly spread from China to countries where IBD are more prevalent, and there is convincing evidence that Covid-19-mediated morbidity and mortality are higher in subjects with comorbidities. The primary objectives of this Viewpoint are to provide a focused overview of the factors and mechanisms by which the novel severe acute respiratory syndrome coronavirus 2 [SARS-CoV-2] infects cells and to illustrate the link between such determinants and intestinal inflammation. We also provide clues about the reasons why the overall IBD population might have no increased risk of developing SARS-CoV-2 infection and highlight the potential of cytokine blockers, used to treat IBD patients, to prevent Covid-driven pneumonia.

This was a multicentre case series supported by the European Crohn's and Colitis Organisation [ECCO] and performed as part of the Collaborative Network of Exceptionally Rare case reports [CONFER] project. The aim was to report on whether cutaneous lesions associated with inflammatory bowel disease [IBD] and refractory to standard medical therapy including anti-tumour necrosis factors [anti-TNFs], would respond to the newer biologic agents ustekinumab [UST] or vedolizumab [VDZ]. This report includes 28 patients with cutaneous lesions from 14 centres, all of whom had failed immunomodulator and anti-TNF therapy. Metastatic Crohn's disease [MCD] was diagnosed in 10 patients: UST led to remission in five cases and partial response in four cases, with a single report of VDZ inducing remission. All cases of MCD treated with UST responded after the first or second dose, and the median time for the five cases that attained remission was 5 months. Pyoderma gangrenosum [PG] was diagnosed in four cases: three of these attained remission with UST [median time to remission 4 months] and one case did not respond to VDZ. There were seven cases of erythema nodosum [EN]: UST led to remission in four cases and partial response in 1 case whilst VDZ had partial response in 2 cases and non-response in two cases. There were seven single cases of other inflammatory lesions. In summary, UST appears to be useful for different cutaneous lesions including MCD, PG, and EN, whereas VDZ does not appear to be useful for lesions that are independent of disease activity.

This is a rapid review of the risk of infection with SARS-CoV-2, the risk of symptomatic cases of COVID-19, and the severity of these cases in IBD patients. Guidance on how to manage IBD patients at risk for infection, and IBD patients after infection is provided. The prevention of infection in both patients and health care providers by reducing elective visits and procedures, utilizing telemedicine, and social isolation is also emphasized to maintain health care services for IBD patients during a growing pandemic.

The severe acute respiratory syndrome coronavirus 2 [SARS-CoV-2]-causing coronavirus disease [COVID]-19 pandemic poses major challenges for patients with inflammatory bowel disease [IBD] to be recruited and maintained in clinical trials. However, clinical trials offer patients who have failed multiple drugs access to study medications with alternative modes of action and the potential for relief from inflammation-mediated symptoms. Therefore, the continuation of clinical trials in IBD during the COVID-19 pandemic is important both for participants and for the community of IBD patients, due to the dire need for an expanded therapeutic armamentarium. As the safety of patients in clinical trials is the leading principle, we are providing ten specific rules to guide patients and principal investigators safely through the challenging time.

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.

There have been immediate and profound impacts of SARS-CoV-2 and COVID-19 on healthcare services worldwide with major consequences for non-COVID-19 related healthcare. Alongside efforts to reconfigure services and enable continued delivery of safe clinical care for patients with IBD, consideration must also be given to management of IBD research activity. In many centres there has been an effective shutdown of IBD clinical trial activity as research sites have switched focus to either COVID-19 related research or clinical care only. As a result, the early termination of trial programmes and loss of potentially effective therapeutic options for IBD, has become a real and worrying prospect. Moreover, in many countries research activity has become embedded into clinical care - with clinical trials often providing access to new therapies or strategies - which would otherwise not have been available in standard clinical pathways. This pandemic has significant implications for the design, conduct, analysis and reporting of clinical trials in IBD. In this Viewpoint, we share our experiences from a clinical and academic perspective in the United Kingdom, highlighting the early challenges encountered and consider implications for patients and staff at research sites, sponsors, research ethics committees, funders and regulators. We also offer potential solutions both for now and for when we enter a recovery phase from the pandemic.

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.
