Diagnosis and management of immune checkpoint inhibitor colitis

Increased use of immune checkpoint inhibitors (ICIs) has created a rise in immune-related adverse events (irAEs), which may affect any system in the body. Gastrointestinal (GI) irAEs such as immune-mediated colitis are common, occurring in 35% to 50% of patients receiving ICIs. GI irAEs usually develop 6 to 8 weeks after ICI initiation and can involve any part of the GI system. Patients with immune-mediated colitis are categorized into 1 of 5 grades based on the National Cancer Institute’s Common Terminology Criteria for Adverse Events, which also guide treatment decisions. An infectious cause for the diarrhea should be excluded in all patients. Patients with grade 1 symptoms are managed conservatively. Patients with grade 2 or higher symptoms should undergo a colonoscopy and are treated with systemic corticosteroids and, depending on their response, biologic therapy. The aim of this article is to review the diagnosis and management of patients with immune-mediated colitis, which should be identified early and addressed promptly to avoid detrimental outcomes. © 2021 Gastro-Hep Communications, Inc..

An Expert Opinion/Approach: Clinical Presentations, Diagnostic Considerations, and Therapeutic Options for Gastrointestinal Manifestations of Common Variable Immune Deficiency

Common variable immunodeficiency (CVID) is the most common symptomatic primary immunodeficiency. It is characterized by impaired B-cell differentiation. Although patients can be diagnosed with CVID anytime during their lifetime, most patients have symptoms for 5-9 years before their diagnosis. The diagnosis of CVID starts with a detailed history focusing on the infectious and noninfectious manifestations of the disease. In patients who are suspected to experience CVID, quantitative immunoglobulins (Ig) should be checked to confirm the diagnosis. IgG should be at least 2 times less than the age-specific SD along with either a low IgA or IgM and with evidence of impaired vaccine response. CVID is usually associated with infectious and/or noninfectious conditions, the latter of which can be inflammatory, autoimmune, lymphoproliferative, or malignant, among other manifestations. Ig therapy has positively affected the disease course of patients with infectious complications but has limited effect on the noninfectious manifestations because the noninfectious complications are related to immune dysregulation involving B cells and T cells rather than primarily due to antibody deficiency. When the gastrointestinal (GI) system is involved, patients with CVID may display signs and symptoms that mimic several GI conditions such as celiac disease, pernicious anemia, or inflammatory bowel diseases. The inflammatory bowel disease-like condition is usually treated with steroids, 5-aminosalicylates, thiopurines, or biologic agents to control the inflammation. In this review, the clinical presentations, diagnostic considerations, and therapeutic options for GI manifestations of CVID will be discussed to facilitate the individualized management of these often-complex patients. © 2021 American Heart Association, Inc

Efficacy of Fecal Microbiota Transplantation in the Treatment of Active Ulcerative Colitis: A Systematic Review and Meta-Analysis of Double-Blind Randomized Controlled Trials

Background: Fecal microbiota transplantation (FMT) has been investigated as a treatment option for patients with inflammatory bowel disease with controversial results. We sought to perform a systematic review and meta-analysis to evaluate the benefit of FMT in patients with ulcerative colitis. Methods: Double-blind randomized controlled trials (RCTs) including adult patients with active ulcerative colitis who received either FMT or placebo were eligible for inclusion. Outcomes of interest included the rate of combined clinical and endoscopic remission, endoscopic remission or response, clinical remission or response, and specific adverse events. The results were pooled together using Reviewer Manager 5.4 software. Publication bias was assessed using the Egger's test. Results: Six RCTs involving 324 patients were included. Our findings demonstrate that compared with placebo, FMT has significant benefit in inducing combined clinical and endoscopic remission (odds ratio, 4.11; 95% confidence interval, 2.19-7.72; P <. 0001). Subgroup analyses of influencing factors showed no differences between pooled or single stool donors (P =. 71), fresh or frozen FMT (P =. 35), and different routes or frequencies of delivery (P =. 80 and. 48, respectively). Pre-FMT antibiotics, bowel lavage, concomitant biologic therapy, and topical rectal therapy did not affect combined remission rates (P values of. 47,. 38,. 28, and. 40, respectively). Clinical remission or response and endoscopic remission or response were significantly higher in patients who received FMT compared with placebo (P <. 05) without any differences in serious or specific adverse events. Conclusions: FMT demonstrated a clinical and endoscopic benefit in the short-term treatment of active ulcerative colitis, with a comparable safety profile to placebo. Future RCTs are required to standardize study protocols and examine data on maintenance therapy. © 2022 The Author(s). Published by Oxford University Press on behalf of Crohn's & Colitis Foundation.

Knowledge, attitudes, and preventive practices about colorectal cancer among adults in an area of Southern Italy

<p>Abstract</p> <p>Background</p> <p>Colorectal cancer (CRC) is the second most commonly diagnosed cancer for both sexes in developed countries. This study assessed the knowledge, attitudes, and preventive practices regarding CRC of adults in Italy.</p> <p>Methods</p> <p>A random sample of 1165 adults received a self-administered questionnaire on socio-demographic characteristics; knowledge regarding definition, risk factors, and screening; attitudes regarding perceived risk of contracting CRC and utility of screening tests; health-related behaviors and health care use; source of information.</p> <p>Results</p> <p>Only 18.5% knew the two main modifiable risk factors (low physical activity, high caloric intake from fat) and this knowledge was significantly associated with higher educational level, performing physical activity, modification of dietary habits and physical activity for fear of contracting CRC, and lower risk perception of contracting CRC. Half of respondents identified fecal occult blood testing (FOBT) as main test for CRC prevention and were more knowledgeable those unmarried, more educated, who knew the main risk factors of CRC, and have received advice by physician of performing FOBT. Personal opinion that screening is useful for CRC prevention was high with a mean score of 8.3 and it was predicted by respondents' lower education, beliefs that CRC can be prevented, higher personal perceived risk of contracting CRC, and information received by physician about CRC. An appropriate behavior of performing FOBT if eligible or not performing if not eligible was significantly higher in female, younger, more educated, in those who have been recommended by physician for undergo or not undergo FOBT, and who have not personal history of precancerous lesions and familial history of precancerous lesions or CRC.</p> <p>Conclusion</p> <p>Linkages between health care and educational systems are needed to improve the levels of knowledge and to raise CRC screening adherence.</p

P660 Knowledge, attitudes, and awareness of contraceptive choices in women with Inflammatory Bowel Disease

Abstract Background Active inflammatory bowel disease (IBD) at conception is associated with adverse pregnancy outcomes. Published literature suggests that almost a quarter of women with IBD do not use any form of contraception putting them at risk of unplanned pregnancy. Recent guidelines emphasise the importance of antenatal care in IBD patients, but contraception counselling and risk assessment are not addressed. Our aim was to explore the contraceptive knowledge, attitudes and preferences of women with IBD. Methods A 34-item questionnaire was prospectively administered to 245 consecutive female IBD patients aged 18–45 attending gastroenterology clinics. Disease control was measured using the validated IBD Control questionnaire, and contraceptive preferences assessed by the Contraceptive Features Survey. Results Of the 245 participants (see table 1), mean disease duration was 6.5 years, median IBD control score was 16.9 (range 0- 26), and 152 (62%) respondents had previously been pregnant. Almost three quarters of respondents (n=176) reported currently using contraception, and 41 (17%) were using highly effective contraceptives. The most commonly used contraceptives were oral birth control pills (27%) and barrier methods (18%). Participants who identified as Caucasian (74%) were more likely than those who identified as Asian (37%) to use contraception (p=0.0009). Patients who did not plan to conceive in the future were more likely to use contraception (p=0.0365). However, of the 58% (n=143) who had either no plans to conceive in the future or were unsure, 23% were not using any form of contraception, and 83% were not using a highly effective contraceptive. Current biologic therapy was significantly associated with highly effective contraceptive use (p=0.0275). Contraceptive features most important to women were effectiveness (78%), ease of use (76%), few or no side effects (68%) and not detracting from sexual enjoyment (65%). Only 25% patients (n=61) recalled discussing reproductive issues with their IBD clinician, however, 86% stated they would feel comfortable having this discussion. Women wished to receive family planning counselling from their IBD nurse (81%), General practitioner (77%), IBD doctor (68%), and gynaecologist (47%). Conclusion A quarter of patients in our cohort were not using any contraception and the majority were not using a highly effective form potentially increasing their risk of unplanned or mistimed pregnancy. Participants desired a contraceptive that was effective, easy to use and with minimal side effects. Our findings reflect the need for further studies to improve informed decision making with contraceptive counselling, to improve the overall quality of care for women with IBD. </jats:sec

Faecal Calprotectin from Ileostomy Output Is Sensitive and Specific for the Prediction of Small Bowel Inflammation in Patients with Crohn’s Disease

Abstract Background Severe Crohn’s disease [CD] can result in extensive bowel resections and need for creation of an ileostomy. Faecal calprotectin [FC] is well studied in CD management, though its role in patients who have an ileostomy is unclear. Our aim is to understand if FC is a useful adjunct to radiographic or endoscopic studies in identifying recurrent CD after surgery in patients with an ileostomy. Methods Between January 1, 2017, and September 30, 2020, we searched the Mayo Clinic electronic medical record retrospectively for adult patients with ICD-10 code for CD, and a surgical history of an ileostomy. Patients were included in the analysis if they had at least one FC measured and a concomitant radiographic imaging and/or endoscopic procedure. An abnormal FC was defined as greater than 60 µg/g. Results Of 51 patients who met our inclusion criteria, 17 had an FC level &amp;gt;60 µg/g. Of these 17 patients, 14 had imaging and/or an ileoscopy confirming the presence of small bowel inflammation, with a sensitivity of 87.5%. Of the remaining 34 patients with an FC level ≤60 µg/g, 32 patients had imaging and/or ileoscopy demonstrating no small bowel inflammation, with a specificity of 91.4%. FC from an ileostomy effluent had a positive predictive value of 82.3%, a negative predictive value of 94.1% and test diagnostic accuracy of 90.1%. Conclusion FC from an ileostomy effluent is a highly sensitive and specific test for the assessment and monitoring of small bowel inflammation and disease recurrence in patients with CD. </jats:sec
