Clinical Decision Making in Inflammatory Bowel Disease Mimics: Practice Management from Inflammatory Bowel Disease LIVE.

Background: Since 2009, inflammatory bowel disease (IBD) specialists have utilized "IBD LIVE," a weekly live video conference with a global audience, to discuss the multidisciplinary management of their most challenging cases. While most cases presented were confirmed IBD, a substantial number were diseases that mimic IBD. We have categorized all IBD LIVE cases and identified "IBD-mimics" with consequent clinical management implications. Methods: Cases have been recorded/archived since May 2018; we reviewed all 371 cases from May 2018-February 2023. IBD-mimics were analyzed/categorized according to their diagnostic and therapeutic workup. Results: Confirmed IBD cases made up 82.5% (306/371; 193 Crohn's disease, 107 ulcerative colitis, and 6 IBD-unclassified). Sixty-five (17.5%) cases were found to be mimics, most commonly medication-induced (n = 8) or vasculitis (n = 7). The evaluations that ultimately resulted in correct diagnosis included additional endoscopic biopsies (n = 13, 21%), surgical exploration/pathology (n = 10, 16.5%), biopsies from outside the GI tract (n = 10, 16.5%), genetic/laboratory testing (n = 8, 13%), extensive review of patient history (n = 8, 13%), imaging (n = 5, 8%), balloon enteroscopy (n = 5, 8%), and capsule endoscopy (n = 2, 3%). Twenty-five patients (25/65, 38%) were treated with biologics for presumed IBD, 5 of whom subsequently experienced adverse events requiring discontinuation of the biologic. Many patients were prescribed steroids, azathioprine, mercaptopurine, or methotrexate, and 3 were trialed on tofacitinib. Conclusions: The diverse presentation of IBD and IBD-mimics necessitates periodic consideration of the differential diagnosis, and reassessment of treatment in presumed IBD patients without appropriate clinical response. The substantial differences and often conflicting treatment approaches to IBD versus IBD-mimics directly impact the quality and cost of patient care.

Lifestyle Factors and Silent Inflammatory Bowel Disease.

Introduction: Hypoalgesic or silent inflammatory bowel disease (IBD) is a poorly understood condition that has been associated with poor clinical outcomes. There is evidence that lifestyle factors, including diet, exercise, and substance use can influence inflammatory activity and symptoms in IBD. It is unclear, though, whether these issues impact pain experience in IBD. We performed this study to evaluate the potential relationship between several key lifestyle factors and silent IBD. Methods: We performed a retrospective analysis using an IBD natural history registry based in a single tertiary care referral center. We compared demographic and clinical features in 2 patient cohorts defined using data from simultaneous pain surveys and ileocolonoscopy: (a) active IBD without pain (silent IBD) and (b) active IBD with pain. We also evaluated the relative incidence of characteristics related to diet, exercise, sexual activity, and substance abuse. Results: One hundred and eighty IBD patients had active disease and 69 (38.3%) exhibited silent IBD. Silent IBD patients exhibited incidences of disease type, location, and severity as pain-perceiving IBD patients. Silent IBD patients were more likely to be male and less likely to exhibit anxiety and/or depression or to use cannabis, analgesic medication, or corticosteroids. There were no significant differences in dietary, exercise-related, or sexual activities between silent and pain-perceiving IBD patients. Conclusions: Silent IBD was associated with reduced incidence of substance and analgesic medication use. No relationships were found between silent IBD and diet, exercise, or sexual activity, though specific elements of each require further dedicated study.

Lifestyle Factors Associated with Abdominal Pain in Quiescent Inflammatory Bowel Disease.

BACKGROUND: Lifestyle factors, including diet, exercise, substance use, and sexual activity, have been shown to influence risk of inflammation and complications in inflammatory bowel disease (IBD), including Crohn's disease (CD) and ulcerative colitis (UC). Little is known about their potential role in abdominal pain generation in IBD. AIMS: We performed this study to evaluate for relationships between lifestyle factors and abdominal pain in quiescent IBD (QP-IBD). METHODS: We performed a retrospective analysis utilizing data from our institution's IBD Natural History Registry (January 1, 2017-December 31, 2022). Endoscopic evaluation, concurrent laboratory studies and surveys were completed by participants. Demographic and clinical data were also abstracted. RESULTS: We identified 177 consecutive patients with quiescent disease (105 females:72 males; 121 with CD:56 with UC) for participation in this study, 93 (52.5%) had QP-IBD. Compared to patients with quiescent IBD without pain (QNP-IBD, patients with QP-IBD exhibited no significant differences in IBD type, location, severity or complication rate. Patients with QP-IBD were more likely to have anxiety/depression (55.9% vs. 32.1%, p = 0.002) and to use antidepressants/anxiolytics (49.5% vs. 21.4%, p < 0.001). They were also less likely to engage in exercise at least three times per week (39.8% vs. 54.8%, p = 0.05) or participate in sexual activity at least monthly (53.8% vs. 69.1%, p = 0.04). On logistic regression analysis, antidepressant and/or anxiolytic use was independently associated with QP-IBD [2.72(1.32-5.62)], while monthly sexual activity was inversely associated [0.48(0.24-0.96)]. CONCLUSION: Lifestyle factors, including the lack of sexual activity and exercise, are significantly associated with QP-IBD. Further study is warranted to clarify the relationships between these factors and the development of abdominal pain in quiescent IBD.

Symptoms associated with healthcare resource utilization in the setting of inflammatory bowel disease.

Several symptoms have been connected to increased healthcare resource utilization (HRU) in the context of inflammatory bowel disease (IBD), including both Crohn's disease (CD) and ulcerative colitis (UC). This study was designed to investigate the prevalence of IBD-associated symptoms and to determine whether any are independently associated with HRU. We undertook a retrospective analysis of data related to consecutive IBD patient encounters from a tertiary care referral center between 1/1/2015 and 8/31/2019. Demographics, clinical activity, endoscopic severity, IBD-related symptom scores, anxiety and depression scores, and other key clinical data were abstracted. Four hundred sixty-seven IBD patients [247f.: 220 m; 315 CD, 142 UC and 11 indeterminate colitis] were included in this study. The most common symptoms were fatigue (83.6%), fecal urgency (68.2%) and abdominal pain (63.5%). Fatigue, abdominal pain, anxiety or depression, corticosteroids, and opioids were each positively associated with HRU, while NSAID and mesalamine use were inversely associated on bivariate analysis. The only factor that demonstrated a statistically significant association with HRU in the whole cohort on multivariable analysis was abdominal pain. Abdominal pain is independently associated with HRU and should be specifically screened for in IBD patients to identify individuals at risk of undergoing expensive interventions. This study also reinforces the importance of optimizing diagnostic and therapeutic management of abdominal pain in IBD.

COVID-19 Vaccine Hesitancy in Patients with Inflammatory Bowel Disease.

BACKGROUND AND AIMS: COVID-19 vaccine hesitancy varies across the USA. Data on COVID-19 vaccine hesitancy in patients with inflammatory bowel disease (IBD) are lacking. We assessed COVID-19 vaccine hesitancy and its associated variables in patients with IBD. METHODS: We evaluated voluntary patient survey responses during routine clinical visits to our IBD center. Data collected included demographic and clinical characteristics. Descriptive statistics, univariate and multivariate analyses were performed to evaluate significant associations with COVID-19 vaccine hesitancy. RESULTS: A total of 239 individuals completed the survey. Over a third of respondents (35.6%) expressed hesitancy toward receiving the COVID-19 vaccine due to vaccine safety concerns (49.4%) and efficacy (23.5%), while others reported non-specific concerns (34.1%). On univariate analysis, Crohn's disease (OR 2.33 CI 1.28-4.25 p = 0.0056), use of biologic medications (OR 1.93 CI 1.16-3.23, p = 0.012), previous self-reported vaccine refusal (OR 8.13 CI 2.90-22.82 p = 0.0001), earlier date of survey administration (OR 2.01 CI 1.17-3.44 p = 0.011), and self-reported COVID infection (OR 2.55 CI 1.16-5.61 p = 0.0056) were more likely to be associated with COVID-19 vaccine hesitancy. On multivariate analysis, patient age, previous vaccine refusal and date of survey administration were more likely to be associated with COVID-19 vaccine hesitancy. CONCLUSIONS: Over one-third of patients with IBD expressed COVID-19 vaccine hesitancy. Vaccine safety and efficacy were the most common reasons. Younger age, previous vaccine refusal and earlier date of survey were more likely to be associated with hesitancy. Our findings suggest that there is room for targeted education to improve COVID-19 vaccine uptake in patients with IBD.

Symptoms and Extraintestinal Manifestations in Active Cannabis Users with Inflammatory Bowel Disease.

Introduction: Cannabis use is common in the setting of inflammatory bowel disease (IBD). Patients frequently use cannabis to treat IBD-associated symptoms, and there is evidence that cannabis and its derivatives are helpful for this purpose. However, it is unclear how the symptom profiles of active IBD cannabis users and nonusers compare and how these symptoms may relate to their underlying disease state and/or complications. Materials and Methods: We performed a retrospective cohort study using a consented IBD natural history registry from a single tertiary care referral center between January 1, 2015 and August 31, 2020. We asked patients about current cannabis use and frequency. We also abstracted demographic and clinical characteristic information, including endoscopic severity, and totals and subscores of surveys assessing IBD characteristics, presence of anxiety/depression, and IBD-associated symptoms. We compared clinical and demographic factors of cannabis users and nonusers and developed a logistic regression model to evaluate for independent associations with cannabis use. Results: Three hundred eighty-three IBD patients met the inclusion criteria (206 females, 177 males; 258 Crohn's disease [CD], 118 ulcerative colitis, and 7 indeterminate colitis). Thirty patients (7.8%) were active cannabis users, consuming it for an average of 2.7 times per week. Cannabis users were more likely to report abdominal pain (83.3% vs. 61.7%), gas (66.7% vs. 45.6%), tenesmus (70.0% vs. 47.6%), and arthralgias (53.3% vs. 20.3%) compared to those that did not use cannabis (p<0.05 for each). Incidence of moderate-severe endoscopic inflammation was similar between cannabis users and nonusers, while CD-associated complications were more common in nonusers (39.1% vs. 69.7%, p<0.05). The only factor that demonstrated a significant association with cannabis use on multivariable analysis was arthralgia (p<0.01). Discussion: Active IBD cannabis users were more likely to report a variety of symptoms, including abdominal pain, gas, tenesmus, and arthralgias. However, they did not demonstrate more frequent active disease or IBD-associated complications, suggesting that other nonluminal factors influence their symptoms and/or decision to use cannabis. These findings demonstrate the importance of evaluating for extraintestinal contributors to symptom burden in IBD cannabis users, as well as the ongoing need to develop safer and more effective methods for recognizing and managing abdominal pain and other symptoms in this setting.

Abdominal pain in quiescent inflammatory bowel disease.

OBJECTIVES: Inflammation is an important driver of abdominal pain in inflammatory bowel disease (IBD). However, some patients in remission still experience pain. We aimed to identify risk factors associated with abdominal pain in quiescent IBD (QP-IBD) and to characterize differences from patients with active disease experiencing pain (AP-IBD). METHODS: We performed a retrospective analysis utilizing data from our institution's IBD Natural History Registry (January 1, 2015-August 31, 2018). Endoscopic evaluation, concurrent laboratory studies, and validated surveys were completed by participants. Demographic and clinical data were also abstracted. RESULTS: We recruited 122 patients with quiescent disease (65f:57 m; 93CD:26UC:3Indeterminate) for participation in this study, 74 (60.7%) had QP-IBD. QP-IBD patients were more likely to have anxiety/depression (71.6% vs. 25.0%, p < 0.001) or to use antidepressants (47.3% vs. 22.9%, p < 0.010), opiates (18.9% vs. 2.1%, p < 0.010), other pain medications (50.0% vs. 18.8%, p < 0.010), or corticosteroids (18.9% vs. 2.1%, p < 0.010). On logistic regression analysis, corticosteroid use, anxious/depressed state, and female gender were each independently associated with QP-IBD (p < 0.050 or less). Compared with AP-IBD patients (n = 110, 59f:51 m; 69CD:38UC:3Indeterminate), QP-IBD patients were more likely to use antidepressants (45.6% vs. 26.4%, p < 0.010). Platelet, white blood cell, C-reactive protein, and sedimentation rate levels were all less likely to be elevated in QP-IBD (all p < 0.050), though 44% exhibited pathological elevation in at least one. DISCUSSION: QP-IBD was independently associated with corticosteroid use, anxiety/depression, and female gender. Compared with AP-IBD, QP-IBD patients were more likely to use antidepressants and less likely to exhibit elevated inflammatory markers. However, many QP-IBD patients still demonstrated pathological elevation of these tests, demonstrating the need to develop new noninvasive screening methods for this condition.

Gastrointestinal hypoalgesia in inflammatory bowel disease.

BACKGROUND: Pain perception is critical for detection of noxious bodily insults. Gastrointestinal hypoalgesia in inflammatory bowel disease (IBD) is a poorly understood phenomenon previously linked to poor patient outcomes. We aimed to evaluate the risk factors associated with this condition and to discern characteristics that might differentiate these patients from pain-free quiescent counterparts. METHODS: We performed a retrospective analysis using an IBD natural history registry based in a single tertiary care referral center. We compared demographic and clinical features in 3 patient cohorts defined using data from simultaneous pain surveys and ileocolonoscopy: a) active IBD without pain (hypoalgesic IBD); b) active IBD with pain; and c) inactive IBD without pain. RESULTS: One hundred fifty-three IBD patients had active disease and 43 (28.1%) exhibited hypoalgesia. Hypoalgesic IBD patients were more likely to develop non-perianal fistulae (P=0.03). On logistic regression analysis, hypoalgesic IBD was independently associated with male sex, advancing age and mesalamine use, and inversely associated with anxious/depressed state and opiate use. Hypoalgesic IBD patients were demographically and clinically similar to the pain-free quiescent IBD cohort (n=59). Platelet count and C-reactive protein were more likely to be pathologically elevated in hypoalgesic IBD (P=0.03), though >25% did not exhibit elevated inflammatory markers. CONCLUSIONS: Hypoalgesia is common in IBD, particularly in male and older individuals, and is associated with an increased incidence of fistulae and corticosteroid use. Novel noninvasive diagnostic tools are needed to screen for this population, as inflammatory markers are not always elevated.

Increased Risk of Influenza and Influenza-Related Complications Among 140,480 Patients With Inflammatory Bowel Disease.

Background: Diseases of immune dysregulation are associated with an increased risk of viral infections, some of which may be preventable. To date, there are very limited data on the incidence and risk of influenza and related complications in patients with inflammatory bowel disease (IBD). Furthermore, the impact of immunosuppressive medications on that risk is unclear. Therefore, the aim of this study was to estimate the incidence and severity of influenza infections in IBD patients. In addition, we looked specifically at the effect of medications on influenza risk. Methods: Using the MarketScan Database (January 2008 to December 2011), we conducted a retrospective cohort study to estimate the incidence of influenza and risk of related complications in IBD patients compared with those without IBD. We employed a nested case-control study design to evaluate the potential independent effect of IBD medications on influenza risk. Results: A total of 140,480 patients with IBD and non-IBD controls were studied. There were 2963 patients with influenza compared with 1941 non-IBD subjects. Inflammatory bowel disease patients had an increased influenza risk compared with those without IBD (incidence rate ratio, 1.54; 95% confidence interval [CI], 1.49-1.63). A higher rate of hospitalizations (162/2994 [5.4%] vs 36/1941 [1.85%]; P < 0.001) was noted. Systemic corticosteroids were found to be independently associated with influenza (odds ratio, 1.22; 95% CI, 1.08-1.38). Conclusions: Inflammatory bowel disease patients had an increased risk of influenza compared with those without IBD and were more likely to require hospitalization. Steroids were the only medication class independently associated with flu risk.

Anxiety, depression, and inflammation after restorative proctocolectomy.

PURPOSE: Anxiety and depression (A&D) are more common in inflammatory bowel disease (IBD) and in IBD patients who undergo proctocolectomy with ileal pouch-anal anastomosis (IPAA). Our aim was to test the hypothesis that chronic inflammatory conditions in IPAA are associated with increased incidence of A&D. METHODS: Retrospective cohort study at a single tertiary care referral center using a consented IBD and colon cancer natural history registry. Demographic and clinical factors, including surgical and psychiatric history, were abstracted. RESULTS: We compared A&D rate in three cohorts: (1) ulcerative proctocolitis with IPAA (UC) (n = 353), (2) Crohn's disease/indeterminate proctocolitis with IPAA (CDIC) (n = 49), and (3) familial adenomatous polyposis with IPAA (FAP) (n = 33). Forty-six CDIC patients (93.9%) demonstrated pouch-related inflammation, while 126 UC patients (35.7%) and 2 FAP patients (6.1%) developed pouchitis. CDIC had a higher rate of A&D co-diagnosis compared to UC and FAP (20.4 vs.12.7 vs.12.1% respectively; p < 0.05). UC patients with pouchitis also exhibited a higher rate of A&D than UC without pouchitis (19.8 vs.8.8%; p < 0.05). Multivariable analysis demonstrated that pre-operative corticosteroid use (OR = 4.46, CI = 1.34-14.87, p < 0.05), female gender (OR = 2.19, CI = 1.22-3.95, p < 0.01), tobacco use (OR = 2.92, CI = 1.57 = 5.41, p < 0.001), and pouch inflammation (OR = 2.37, CI = 1.28-4.39, p < 0.05) were each independently associated with A&D in these patients. CONCLUSIONS: Anxiety and depression were more common in patients experiencing inflammatory conditions of the pouch. UC without pouchitis and FAP patients demonstrated lower rates of A&D (that were comparable to the general population), implying that having an IPAA alone was not enough to increase risk for A&D. Factors independently associated with A&D in IPAA included an inflamed pouch, corticosteroid use, smoking, and female gender.

Smoking and the Risk of Pouchitis in Ulcerative Colitis Patients With Ileal Pouch-Anal Anastomosis.

BACKGROUND: Ulcerative colitis (UC) patients who undergo proctocolectomy with ileal pouch-anal anastomosis (IPAA) may develop pouchitis, a poorly understood inflammatory condition. There is controversy over whether tobacco use can protect against pouchitis. We undertook this investigation to further evaluate whether smoking reduces the risk of developing pouchitis and to determine whether other previously associated clinical factors change the risk for pouchitis. METHODS: We performed a retrospective analysis using a consented inflammatory bowel disease (IBD) natural history registry between the years 1995-2015 from a single tertiary care referral center. Demographic data, medical history, surgical information, medication use, laboratory data, and smoking history were abstracted. Former smokers had quit for at least 1 year. The primary end point was development of pouchitis. RESULTS: Of the 353 UC patients with IPAA in this study, 126 (35.6%) developed pouchitis. Prior tobacco use (P < 0.0001) was more common in patients who developed pouchitis. Former and active smokers were more likely to develop pouchitis compared with those without a history of tobacco use (63.4% vs 27.3% respectively, P < 0.001). There was no significant difference in active smoking rate between those without pouchitis and the group that did develop pouchitis. Multivariate analysis demonstrated that the only independent risk factor associated with pouchitis was a history of tobacco use. CONCLUSIONS: These results suggest that smoking cessation may increase the likelihood of developing pouchitis in tobacco users with UC and IPAA, but active smoking does not seem to be more effective in preventing this condition.

Influences and Impact of Anxiety and Depression in the Setting of Inflammatory Bowel Disease.

Background: Individuals with inflammatory bowel disease (IBD) are at increased risk of developing anxiety or depression (A&D). Crohn's disease (CD) and ulcerative colitis (UC) with comorbid A&D are both more challenging to manage. IBD providers need to better understand the causes and impact of A&D in order to improve care for IBD patients. We sought to identify clinical factors that influence development of A&D and healthcare utilization in IBD. Methods: This is a retrospective analysis using an IBD natural history registry from a single tertiary care referral center. Presence of A&D was determined based upon responses to the Hospital Anxiety and Depression Scale. Demographic and clinical factors were abstracted to evaluate for significant associations. Results: Four hundred thirty-two IBD patients (132 UC, 256 CD, and 44 indeterminate colitis) were included in this study. One hundred ninety-two (44.4%) had anxiety or depression or both, and most were female (59.4%, P < 0.05). History of surgery (P < 0.05), female gender (P < 0.05), smoking (P < 0.05), and extra-intestinal manifestations (P < 0.01) were each independently predictive of A&D. Inflammatory bowel disease patients with A&D more often underwent imaging studies (53.6% vs 36.7%, P < 0.05), visited the ED (30.7% vs 20.8%, P < 0.05), or were hospitalized (31.7% vs 21.7%, P < 0.05). They were also more frequently prescribed corticosteroids (50.5% vs 36.7%, P < 0.01) and biologic medications (62.5% vs 51.3%, P < 0.05). Finally, they were more likely to have had at least 1 "no-show" (29.2% vs 16.7%, P < 0.01) and had a higher mean number of "no-shows" (0.69 +/- 0.1 vs 0.30 +/- 0.1, P < 0.01) over the study period. Discussion: Anxiety and depression are common in the setting of IBD and are strongly associated with surgical history, disease complications (including extra-intestinal manifestations), smoking, and female gender. Inflammatory bowel disease patients with A&D are also more likely to require therapy and to utilize healthcare resources. This study refines our understanding of A&D development and its impact in IBD and provides additional considerations for management in this setting.

The inflammatory bowel disease live interinstitutional and interdisciplinary videoconference education (IBD LIVE) series.

BACKGROUND: Managing patients with inflammatory bowel disease requires multidisciplinary coordination. Technological advances have enhanced access to care for patients and improved physician interactions. The primary aim of our project was to convene diverse institutions and specialties through a multisite virtual conferencing platform to discuss complex patient management. METHODS: The case conference is designed to include multiple institutions to exchange ideas, review evidence-based data, and provide input on the management of patients with Crohn's disease and ulcerative colitis. Technology is supplied and coordinated by an information technology specialist and Chorus Call, Inc., an international teleconferencing service provider. The Inflammatory Bowel Disease Live Interinstitutional Interdisciplinary Videoconference Education (IBD LIVE) initiative is accredited by the University of Pittsburgh Medical Center (UPMC) Center for Continuing Education in the Health Sciences for 1 AMA PRA Category 1 Credit per weekly session. RESULTS: IBD LIVE began in 2009 comprising only adult gastroenterology and pediatric gastroenterology from UPMC Presbyterian and Children's Hospitals. Participation steadily increased from 5 sites in 2010 to 11 sites in 2014. Maximum attendance for a single conference was 73 participants with a median of 48. The Continuing Medical Education scores (1 = worst to 5 = best) have a high median overall score (4.6, range 3.2-5.0) with positive responses with regard to the degree to which the conference changed practice. CONCLUSIONS: IBD LIVE has been successful and continues to grow. Implementation of the Crohn's and Colitis Foundation of America Virtual Preceptor Program using the IBD LIVE platform will provide expanded national physician access to this professional education activity.

Chronic use of PPI and H2 antagonists decreases the risk of pouchitis after IPAA for ulcerative colitis.

INTRODUCTION: Bacteria have been implicated in the development of pouchitis after ileal pouch anal anastomosis. The change in gastric pH with the use of proton pump inhibitors and H(2) antagonists may lead to alteration of enteric bacteria. We hypothesized that chronic use of these medications would decrease the incidence of pouchitis. METHODS: Patients who had undergone ileal pouch anal anastomosis for ulcerative colitis were classified by history of pouchitis. Patients were further classified by their use of proton pump inhibitors, H(2) blockers, antacids, and other known risk factors for pouchitis. RESULTS: Eighty-five patients were identified. There was a statistically significant increase in the use of daily acid suppression in patients without pouchitis. There was also a statistically significant increase in the use of antacids in patients without pouchitis. Occasional use of acid suppression did not alter the rate of pouchitis. CONCLUSIONS: Our data suggest that the daily use of proton pump inhibitors, H(2) antagonists, or antacids is associated with a decreased risk of pouchitis in ulcerative colitis. Occasional use of these agents did not seem to afford the same protection. These data suggest that altering the pH of the gastrointestinal tract may influence the development of pouchitis.
