Inpatient Management of Inflammatory Bowel Disease-Related Complications

Self-screening questionnaire for perianal fistulizing disease in patients with Crohn's disease

BACKGROUND/AIMS

A poor prognostic factor for Crohn's disease (CD) includes perianal fistulizing disease, including perianal fistula and/or perianal abscess. Currently, a tool to assess perianal symptoms in patients with CD remains nonexistent. This study aimed to develop a perianal fistulizing disease self-screening questionnaire for patients with CD.

METHODS

This prospective pilot study was conducted at three tertiary referral centers between January 2019 and May 2020. We formulated questions on perianal symptoms, including tenesmus, anal discharge, bleeding, pain, and heat. A 4-point Likert scale was used to rate each question. Patients with CD completed a questionnaire and underwent pelvic magnetic resonance imaging (MRI).

RESULTS

Overall, 93 patients were enrolled, with 51 (54.8%) diagnosed with perianal fistulizing disease, as determined by pelvic MRI. The Spearman correlation findings demonstrated that anal pain (p = 0.450, p < 0.001) and anal discharge (p = 0.556, p < 0.001) were the symptoms that most significantly correlated with perianal disease. For anal pain and discharge, the area under the receiver operating characteristic curve of the scores was significantly higher than that of the combined score for all five symptoms (0.855 vs. 0.794, DeLong's test p = 0.04). For the two symptoms combined, the sensitivity, specificity, and positive predictive and negative predictive values were 88.2, 73.8, 80.4, and 83.8%, respectively, with 81.7% accuracy for detecting perianal fistulizing disease.

CONCLUSION

This study indicates that simple questions regarding anal pain and discharge can help accurately identify the presence of perianal fistulizing disease in patients with CD.

Polysaccharide from Pleurotus tuber-regium mycelium improves DSS-induced colitis in mice by regulating inflammatory cytokines, oxidative stress and gut microbiota

Pleurotus tuber-regium (PTR) has been proved to have obvious pharmacological properties. In this study, a polysaccharide was extracted from the mycelium of PTR and administered to DSS-induced colitis mice to clarify the protective effect and mechanism of the PTR polysaccharide (PTRP) on colitis. The results showed that PTRP significantly improved the clinical symptoms and intestinal tissue damage caused by colitis and inhibited the secretion of pro-inflammatory cytokines and myeloperoxidase activity, while the levels of oxidative stress factors in mice decreased and the antioxidant capacity increased. The 16S rRNA sequencing of the mouse cecum content showed that PTRP changed the composition of gut microbiota, and the diversity and abundance of beneficial bacteria increased. In addition, PTRP also enhanced the production of short-chain fatty acids by regulating gut microbiota. In conclusion, our study shows that PTRP has the potential to relieve IBD symptoms and protect intestinal function by regulating inflammatory cytokines, oxidative stress and gut microbiota.

Traditional herbal pair Portulacae Herba and Granati Pericarpium alleviates DSS-induced colitis in mice through IL-6/STAT3/SOCS3 pathway

BACKGROUND

Portulacae Herba and Granati Pericarpium pair (PGP) is a traditional Chinese herbal medicine treatment for colitis, clinically demonstrating a relatively favorable effect on relieving diarrhea and abnormal stools. However, the underlying mechanism remain uncertain.

PURPOSE

The present study intends to evaluate the efficacy of PGP in treating colitis in mice and investigate its underlying mechanism.

METHODS

The protective effect of PGP against colitis was determined by monitoring body weight, colon length, colon weight, and survival rate in mice. Colonic inflammation was assessed by serum cytokine levels, colonic H&E staining, and local neutrophil infiltration. The reversal of intestinal epithelial barrier damage by PGP was subsequently analyzed with Western blot and histological staining. Furthermore, RNA-seq analysis and molecular docking were performed to identify potential pathways recruited by PGP. Following the hints of the transcriptomic results, the role of PGP through the IL-6/STAT3/SOCS3 pathway in DSS-induced colitis mice was verified by Western blot.

RESULTS

DSS-induced colitis in mice was significantly curbed by PGP treatment. PGP treatment significantly mitigated DSS-induced colitis in mice, as evidenced by improvements in body weight, DAI severity, survival rate, and inflammatory cytokines levels in serum and colon. Moreover, PGP treatment up-regulated the level of Slc26a3, thereby increasing the expressions of the tight junction/adherens junction proteins ZO-1, occludin and E-cadherin in the colon. RNA-seq analysis revealed that PGP inhibits the IL-6/STAT3/SOCS3 pathway at the transcriptional level. Molecular docking indicated that the major components of PGP could bind tightly to the proteins of IL-6 and SOCS3. Meanwhile, the result of Western blot revealed that the IL-6/STAT3/SOCS3 pathway was inhibited at the protein level after PGP administration.

CONCLUSION

PGP could alleviate colonic inflammation and reverse damage to the intestinal epithelial barrier in DSS-induced colitis mice. The underlying mechanism involves the inhibition of the IL-6/STAT3/SOCS3 pathway.

Heterogeneity in Psychological Adaptation Patterns and Its Predictive Factors Among Patients with Inflammatory Bowel Disease: A Latent Profile Analysis

Purpose

To identify the distinct profiles of psychosocial adaptation of Chinese inflammatory bowel disease (IBD) patients and the predictive factors.

Patients and Methods

A cross-sectional survey method was used to recruit 263 IBD patients who were treated in a tertiary hospital in Shandong Province from July 2022 to April 2023. The general information questionnaire, Inflammatory Bowel Disease Psychosocial Adaptation Questionnaire, Resilience Scale for Inflammatory Bowel Disease, Chinese Benefit Finding Scale, and Stigma Scale for Chronic Illnesses, Medical Coping Modes Questionnaire and Inflammatory Bowel Disease-Disk were used as the instruments for investigation. Latent profile analysis was conducted with the six dimensions of the IBD Psychosocial Adaptation Questionnaire as the explicit indicators. The predictors of profile membership were analyzed by multinomial logistic regressions.

Results

Four profiles of psychosocial adaptation in IBD patients were identified: Low level psychosocial adaptation (14.1%), Medium level psychosocial adaptation - High body image distress (25.5%), Medium level psychosocial adaptation - Low body image distress (30.0%) and High level psychosocial adaptation (30.4%). Compared with Low level psychosocial adaptation group, High level psychosocial adaptation group had a higher level of positive cognition (OR=2.930, 95%IC 0.017-0.305, p< 0.001) and overall psychological resilience (OR=1.832, 95%IC 0.000-0.016, p < 0.001), more health behaviors (OR= 2.520, 95%IC 0.191-1.358, p=0.001), a lower level of internal stigma (OR=0.135, 95%IC 0.043-0.420, p < 0.001) and overall stigma (OR=0.010, 95%IC 0.003-0.118, p=0.001), less acceptance-resignation coping style (OR=0.055, 95%IC 0.209-3.200, p < 0.001) and lower disease burden (OR=0.407, 95%IC 0.298-0.698, p=0.006).

Conclusion

About a half of IBD patients had a medium level of psychosocial adaptation. Psychological resilience, benefit finding, stigma, medical coping styles and disease burden predicted psychosocial adaptation profiles. Healthcare providers need to focus on the heterogeneity of psychosocial adaptation of IBD patients and formulate personalized intervention programs for patients with different profiles to improve their psychosocial adaptation.

Probiotics for the treatment of ulcerative colitis: a review of experimental research from 2018 to 2022

Ulcerative colitis (UC) has become a worldwide public health problem, and the prevalence of the disease among children has been increasing. The pathogenesis of UC has not been elucidated, but dysbiosis of the gut microbiota is considered the main cause of chronic intestinal inflammation. This review focuses on the therapeutic effects of probiotics on UC and the potential mechanisms involved. In animal studies, probiotics have been shown to alleviate symptoms of UC, including weight loss, diarrhea, blood in the stool, and a shortened colon length, while also restoring intestinal microecological homeostasis, improving gut barrier function, modulating the intestinal immune response, and attenuating intestinal inflammation, thereby providing theoretical support for the development of probiotic-based microbial products as an adjunctive therapy for UC. However, the efficacy of probiotics is influenced by factors such as the bacterial strain, dose, and form. Hence, the mechanisms of action need to be investigated further. Relevant clinical trials are currently lacking, so the extension of animal experimental findings to clinical application requires a longer period of consideration for validation.

Azelaic Acid Regulates the Renin-Angiotensin System and Improves Colitis Based on Network Pharmacology and Experimentation

Inflammatory bowel disease (IBD), which encompasses Crohn's disease and ulcerative colitis, has a complicated etiology that might be brought on by metabolic dysbiosis. Previous metabonomic studies have found a correlation between decreased azelaic acid (AzA) and IBD. Herein, data from the Metabolomics Workbench showed that the content of AzA decreased in IBD patients (PR000639) and dextran sulfate sodium (DSS)-induced mice (PR000837). The effects of AzA on IBD were then examined using a DSS-induced mouse model, and the results demonstrated that AzA alleviated clinical activity, decreased pro-inflammatory cytokine production, and reduced CD4⁺CD25⁺Foxp3⁺Treg percentages in mesenteric lymph nodes. Through network pharmacology analysis, we discovered 99 candidate IBD-associated genes that are potentially regulated by AzA. After the enrichment analysis of the candidate genes, the renin-angiotensin system (RAS) pathway was one of the most substantially enriched pathways. Additionally, AzA reversed the increased expression of important RAS components (ACE, ACE2, and MAS1L) following DSS induction, suggesting that AzA exerts therapeutic effects possibly via the RAS pathway. This study suggests that AzA may be a promising drug for treating IBD.

Burden and Trends of IBD in 5 Asian Countries From 1990 to 2019: A Comparison With the United States and the United Kingdom

BACKGROUND

IBD is becoming a global health challenge, with substantial variations in incidence and death rates between Eastern and Western countries.

OBJECTIVE

This study aimed to investigate the burden and trends of IBD in 5 Asian countries, the United States, and the United Kingdom.

DESIGN

This was a cross-sectional study.

SETTING

Data were obtained from Global Burden of Disease 2019 Study.

PATIENTS

Patients with IBD were included.

MAIN OUTCOME MEASURES

Incidence, death, and age-standardized rates of IBD were measured.

RESULTS

The age-standardized incidence and rates of death from IBD gradually decreased worldwide from 1990 to 2019. The age-standardized incidence rate in the United States decreased from 1990 to 2000 and then increased gradually from 2000 to 2019; the age-standardized incidence rates in the United Kingdom, Mongolia, and China increased gradually from 1990 to 2019, whereas in the Democratic People's Republic of Korea, it decreased from 1990 to 1995 and increased gradually from 1995 to 2019. The age-standardized death rate in the Republic of Korea exhibited a rising trend until 1995, fell significantly up to 2015, and then stabilized from 2015 to 2019. The age-standardized death rate in the United States showed a rising trend until 2007, and then decreased gradually from 2007 to 2019, whereas the rate in the United Kingdom showed a rising trend until 2010 and decreased from 2010 to 2019. The age-standardized death rates in China, Mongolia, the Democratic People's Republic of Korea, and Japan decreased gradually from 1990 to 2019. The age-standardized incidence and death rates in the United States and United Kingdom in recent decades were higher than those in the 5 Asian countries. The peak age-standardized incidence rates in the 7 countries were among people of 20 to 60 years of age. The age-standardized death rates in all 7 countries exhibited rising trends with increasing age, with older individuals, particularly those aged ≥70 years, accounting for the most deaths.

LIMITATIONS

Limitations of this study include data from different countries with different quality and accuracy.

CONCLUSIONS

There have been large variations in the burdens and trends of IBD between 5 Asian countries, the United States, and the United Kingdom during the past 3 decades. These findings may help policymakers to make better public decisions and allocate appropriate resources. See Video Abstract at http://links.lww.com/DCR/B996 .

Causal Link between Inflammatory Bowel Disease and Fistula: Evidence from Mendelian Randomization Study

BACKGROUND

Previous observational studies have found that fistulas are common in Crohn's disease (CD) and less common in ulcerative colitis (UC). However, some patients have a fistula before diagnosis. Based on retrospective analysis, it was not possible to determine whether there was a bi-directional causal relationship between inflammatory bowel disease (IBD) and fistulas.

METHODS

Data were extracted from the open GWAS database; 25,042 cases and 34,915 controls were included for IBD, and 6926 cases and 30,228 controls were included for fistula. Two-sample Mendelian randomization and multivariable Mendelian randomization were used in combination to determine the causal relationship between IBD and fistula.

RESULTS

Forward MR showed that IBD increased the risk of colonic or urogenital fistula (FISTULA) (OR: 1.09, 95% CI: 1.05 to 1.13, p = 1.22 × 10^-6), mainly associated with fissure and fistula of the anal and rectal regions (FISSANAL) (OR:1.10, 95% CI:1.06 to 1.14, p = 6.12 × 10^-8), but not with fistulas involving the female genital tract (FEMGENFISTUL) (OR:0.97, 95% CI: 0.85 to 1.11, p = 0.669). Furthermore, both UC and CD increased the risk of FISTULA. However, after adjusting by MVMR, only CD increased the risk of FISTULA (OR: 1.06, 95% CI: 1.02 to 1.11, p = 0.004), and UC did not increase the risk of FISTULA (OR: 1.01, 95% CI: 0.95 to 1.06, p = 0.838). Reverse MR showed that fistulas did not increase the risk of IBD.

CONCLUSION

Our study confirms it is CD, rather than UC, that casually leads to an increased risk of fistula, but fistulas do not increase the risk of IBD.

The safe use of inflammatory bowel disease therapies during the COVID-19 pandemic

Background

Patients with inflammatory bowel disease (IBD) often require the use of immunosuppressant medications that increase infection risk, leading to concerns over the safe use of IBD medications during the Coronavirus 19 (COVID-19) pandemic.

Objectives

To summarize available evidence on the safety and appropriate use of IBD medications during the COVID-19 pandemic, particularly in regard to risk of severe COVID-19 outcomes such as hospitalization, respiratory failure, or death for patients on IBD therapeutics.

Conclusions

The majority of IBD medications are safe to continue during the COVID-19 pandemic, with a few notable exceptions. Patients with IBD who do not have COVID-19 should continue their prescribed IBD therapies, although steroids are associated with severe COVID-19 outcomes and should be weaned when possible. Corticosteroids should be tapered and discontinued when possible in patients with IBD who test positive for COVID-19 as well. Patients with IBD who test positive for COVID-19 should hold biologics, thiopurines, methotrexate, and tofacitinib for at least 2 weeks, and those who have symptoms should not restart these medications until symptom resolution. During the COVID-19 pandemic, all patients with IBD should continue to follow public health guidance including social distancing, masking, and COVID-19 vaccination recommendations.

Medical, Endoscopic and Surgical Management of Stricturing Crohn's Disease: Current Clinical Practice

The development of fibrostenotic intestinal disease occurs in approximately one-third of patients with Crohn's disease and is associated with increased morbidity. Despite introducing new biologic agents, stricturing Crohn's disease remains a significant clinical challenge. Medical treatment is considered the first-line treatment for inflammatory strictures, and anti-TNF agents appear to provide the most considerable benefit among the available medical treatments. However, medical therapy is ineffective on strictures with a mainly fibrotic component, and a high proportion of patients under anti-TNF will require surgery. In fibrotic strictures or cases refractory to medical treatment, an endoscopic or surgical approach should be considered depending on the location, length, and severity of the stricture. Both endoscopic balloon dilatation and endoscopic stricturoplasty are minimally invasive and safe, associated with a small risk of complications. On the other hand, the surgical approach is indicated in patients not suitable for endoscopic therapy. This review aimed to present and analyze the currently available medical, endoscopic, and surgical management of stricturing Crohn's disease.

Racial differences in the outcomes of IBD hospitalizations: a national population-based study

PURPOSE

There are  scarce data describing the outcomes of hospitalized patients admitted with inflammatory bowel disease (IBD) stratified by race. In this retrospective cohort study, we evaluated the difference in outcomes between adult white and black patients hospitalized with a principal diagnosis of inflammatory bowel disease.

METHODS

Data were obtained from the 2016 and 2017 National Inpatient Sample (NIS) database. Our primary outcome was inpatient mortality while the secondary outcomes were hospital length of stay (LOS), total hospital charges (THC), red blood cell (RBC) transfusion, diagnosis of bowel perforation, and severe sepsis with septic shock. We conducted the analysis using STATA software. We used propensity-matched multivariate regression analysis to adjust for potential confounders.

RESULTS

Among 71 million hospital hospitalizations, we found 177,574 hospitalizations with a principal diagnosis of IBD, with 24,635 (13.9%) for black patients, 124,899 (70.3%) for white patients, and 28,040 (15.8%) were for others. There was no significant difference in inpatient mortality for black vs white patients. Among secondary outcomes, white compared to black patients had increased odds of having a diagnosis of bowel perforation when admitted with a diagnosis of IBD while there was no difference in the odds of developing septic shock. White patients admitted with a diagnosis of UC were also found to have increased total LOS and THC.

CONCLUSION

White patients hospitalized with a principal diagnosis of IBD had no difference in inpatient mortality or septic shock but had worse outcomes such as increased odds of bowel perforation compared to black patients.

Epidemiology and Natural History of Perianal Crohn's Disease: A Systematic Review and Meta-Analysis of Population-Based Cohorts

BACKGROUND AND AIMS

Perianal Crohn's disease (pCD) is a potentially severe phenotype of CD. We conducted a systematic review with meta-analysis to estimate cumulative incidence, risk factors, and outcomes of pCD in population-based cohort studies.

METHODS

Through a systematic literature review through March 1, 2021, we identified population-based inception cohort studies reporting cumulative incidence of perianal disease (primarily abscess and/or fistula) in patients with CD. We estimated the cumulative incidence of pCD at presentation and 1-, 5-, and 10-year follow-up, and risk factors for perianal disease and outcomes including risk of major (bowel resection, proctectomy, ostomy) and minor perianal (incision and drainage, seton placement, etc.) surgery.

RESULTS

In 12 population-based studies, prevalence of pCD was 18.7% (95% confidence interval [CI], 12.5%-27.0%) with 1-, 5-, and 10-year risk of perianal disease being 14.3% (95% CI, 7.9%-24.6%), 17.6% (95% CI, 11.3%-26.5%), and 18.9% (95% CI, 15.0%-23.4%), respectively. Approximately 11.5% of patients (95% CI, 6.7%-19.0%) had perianal disease at or before CD diagnosis. Colonic disease location and rectal involvement were associated with higher risk of pCD. Overall, 63.3% of patients (95% CI, 53.3-72.3) required minor perianal surgery and 6.4% of patients (95% CI, 1.8%-20.6%) required major abdominal surgery for pCD. Use of biologic therapy for pCD is common and has steadily increased throughout the years.

CONCLUSIONS

Approximately 1 in 5 patients with CD develops perianal disease within 10 years of CD diagnosis, including 11.5% who have perianal disease at presentation. Approximately two-thirds of patients require perianal surgery, with a smaller fraction requiring major abdominal surgery.

Bifidobacterium Longum: Protection against Inflammatory Bowel Disease

The prevalence of inflammatory bowel disease (IBD), which includes ulcerative colitis (UC) and Crohn's disease (CD), increases gradually worldwide in the past decades. IBD is generally associated with the change of the immune system and gut microbiota, and the conventional treatments usually result in some side effects. Bifidobacterium longum, as colonizing bacteria in the intestine, has been demonstrated to be capable of relieving colitis in mice and can be employed as an alternative or auxiliary way for treating IBD. Here, the mechanisms of the Bifidobacterium longum in the treatment of IBD were summarized based on previous cell and animal studies and clinical trials testing bacterial therapies. This review will be served as a basis for future research on IBD treatment.

Medical Management of Aggressive Inflammatory Bowel Disease: When Is the Time to Cut Your (and the Patient's) Losses?

Despite a treatment armamentarium that continues to increase in terms of medical options for the therapy of Crohn's disease (CD) and ulcerative colitis (UC), a significant proportion of patients will require surgical intervention over their disease course. Surgery does not represent a failure of medical therapy in the treatment of patients with inflammatory bowel disease (IBD); rather, surgery represents an integral feature of the multidisciplinary approach to an individual patient. The timing, factors, and potential outcomes of each therapeutic decision in the pre-, peri- and postoperative periods must be weighed by each member of a multidisciplinary team with the goal of improving the quality of life for patients with IBD. In this article, we review the current evidence underlying approaches to the medical and surgical management of complications of CD and UC. We also outline opportunities for tailored decision-making and potentially earlier surgical intervention with the aim of improving long-term outcomes among patients with IBD.

Natural Food Polysaccharides Ameliorate Inflammatory Bowel Disease and Its Mechanisms

Natural polysaccharides and their metabolites’ short chain fatty acids (SCFAs) have attracted much attention. Recently, they have shown great potential in attenuating systemic inflammation activities, especially in inflammatory bowel disease (IBD). IBD is a complex pathological process and is related to epithelial damage and microbiota imbalance in the gut. Recent studies have indicated that natural polysaccharides could improve IBD recovery by different mechanisms. They could not only influence the ratio of intestine microbiota, but also regulate the secretion levels of immunity cytokines through multiple pathways, the latter including modulation of the TLR/MAPK/NF-κB signaling pathways and stimulation of G-protein-coupled receptors. Moreover, they could increase intestinal integrity and modulate oxidative stress. In this review, recent research about how natural polysaccharides impact the pathogenesis of IBD are summarized to prove the association between polysaccharides and disease recovery, which might contribute to the secretion of inflammatory cytokines, improve intestine epithelial damage, reduce oxidative stress, sustain the balanced microenvironment of the intestines, and finally lower the risk of IBD.

Exploitation of Marine-Derived Robust Biological Molecules to Manage Inflammatory Bowel Disease

Naturally occurring biological entities with extractable and tunable structural and functional characteristics, along with therapeutic attributes, are of supreme interest for strengthening the twenty-first-century biomedical settings. Irrespective of ongoing technological and clinical advancement, traditional medicinal practices to address and manage inflammatory bowel disease (IBD) are inefficient and the effect of the administered therapeutic cues is limited. The reasonable immune response or invasion should also be circumvented for successful clinical translation of engineered cues as highly efficient and robust bioactive entities. In this context, research is underway worldwide, and researchers have redirected or regained their interests in valorizing the naturally occurring biological entities/resources, for example, algal biome so-called "treasure of untouched or underexploited sources". Algal biome from the marine environment is an immense source of excellence that has also been demonstrated as a source of bioactive compounds with unique chemical, structural, and functional features. Moreover, the molecular modeling and synthesis of new drugs based on marine-derived therapeutic and biological cues can show greater efficacy and specificity for the therapeutics. Herein, an effort has been made to cover the existing literature gap on the exploitation of naturally occurring biological entities/resources to address and efficiently manage IBD. Following a brief background study, a focus was given to design characteristics, performance evaluation of engineered cues, and point-of-care IBD therapeutics of diverse bioactive compounds from the algal biome. Noteworthy potentialities of marine-derived biologically active compounds have also been spotlighted to underlying the impact role of bio-active elements with the related pathways. The current review is also focused on the applied standpoint and clinical translation of marine-derived bioactive compounds. Furthermore, a detailed overview of clinical applications and future perspectives are also given in this review.

How to manage inflammatory bowel disease during the COVID-19 pandemic: A guide for the practicing clinician

Managing inflammatory bowel disease (IBD) during the coronavirus disease 2019 (COVID-19) pandemic has been a challenge faced by clinicians and their patients, especially concerning whether to proceed with biologics and immunosuppressive agents in the background of a global outbreak of a highly contagious new coronavirus (severe acute respiratory syndrome coronavirus 2, SARS-CoV-2). The knowledge about the impact of this virus on patients with IBD, although it is still scarce, is rapidly evolving. In particular, concerns surrounding medications' impact for IBD on the risk of acquiring SARS-CoV-2 infection or developing COVID-19, and potentially exacerbate viral replication and the COVID-19 course, are a current thinking of both practicing clinicians and providers caring for patients with IBD. Managing patients with IBD infected with SARS-CoV-2 depends on both the clinical activity of the IBD and the occasional development and severity of COVID-19. In this review, we summarize the current data regarding gastrointestinal involvement by SARS-CoV-2 and pharmacologic and surgical management for IBD concerning this infection, and the COVID-19 impact on both the patient's psychological functioning and endoscopy services, and we concisely summarize the telemedicine roles during the COVID-19 pandemic.

AGA Clinical Practice Update on Management of Inflammatory Bowel Disease During the COVID-19 Pandemic: Expert Commentary

The purpose of this American Gastroenterological Association (AGA) Institute Clinical Practice Update was to rapidly review the emerging evidence and provide timely expert recommendations regarding the management of patients with inflammatory bowel disease during the coronavirus disease 2019 pandemic. This expert commentary was commissioned and approved by the AGA Institute Clinical Practice Updates Committee and the AGA Governing Board to provide timely perspective on a topic of high clinical importance to the AGA membership, and underwent internal peer review by the Clinical Practice Updates Committee and external peer review through standard procedures of Gastroenterology.

Management of Acute Severe Ulcerative Colitis in a Pregnant Woman With COVID-19 Infection: A Case Report and Review of the Literature

First detected in Wuhan, China, the novel 2019 severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is an enveloped RNA beta-coronavirus responsible for an unprecedented, worldwide pandemic caused by COVID-19. Optimal management of immunosuppression in inflammatory bowel disease (IBD) patients with COVID-19 infection currently is based on expert opinion, given the novelty of the infection and the corresponding lack of high-level evidence in patients with immune-mediated conditions. There are limited data regarding IBD patients with COVID-19 and no data regarding early pregnancy in the era of COVID-19. This article describes a patient with acute severe ulcerative colitis (UC) during her first trimester of pregnancy who also has COVID-19. The case presentation is followed by a review of the literature to date on COVID-19 in regard to inflammatory bowel disease and pregnancy, respectively.
