AGA Clinical Practice Guideline on the Management of Pouchitis and Inflammatory Pouch Disorders

BACKGROUND & AIMS

Pouchitis is the most common complication after restorative proctocolectomy with ileal pouch-anal anastomosis for ulcerative colitis. This American Gastroenterological Association (AGA) guideline is intended to support practitioners in the management of pouchitis and inflammatory pouch disorders.

METHODS

A multidisciplinary panel of content experts and guideline methodologists used the Grading of Recommendations Assessment, Development and Evaluation framework to prioritize clinical questions, identify patient-centered outcomes, conduct an evidence synthesis, and develop recommendations for the prevention and treatment of pouchitis, Crohn's-like disease of the pouch, and cuffitis.

RESULTS

The AGA guideline panel made 9 conditional recommendations. In patients with ulcerative colitis who have undergone ileal pouch-anal anastomosis and experience intermittent symptoms of pouchitis, the AGA suggests using antibiotics for the treatment of pouchitis. In patients who experience recurrent episodes of pouchitis that respond to antibiotics, the AGA suggests using probiotics for the prevention of recurrent pouchitis. In patients who experience recurrent pouchitis that responds to antibiotics but relapses shortly after stopping antibiotics (also known as "chronic antibiotic-dependent pouchitis"), the AGA suggests using chronic antibiotic therapy to prevent recurrent pouchitis; however, in patients who are intolerant to antibiotics or who are concerned about the risks of long-term antibiotic therapy, the AGA suggests using advanced immunosuppressive therapies (eg, biologics and/or oral small molecule drugs) approved for treatment of inflammatory bowel disease. In patients who experience recurrent pouchitis with inadequate response to antibiotics (also known as "chronic antibiotic-refractory pouchitis"), the AGA suggests using advanced immunosuppressive therapies; corticosteroids can also be considered in these patients. In patients who develop symptoms due to Crohn's-like disease of the pouch, the AGA suggests using corticosteroids and advanced immunosuppressive therapies. In patients who experience symptoms due to cuffitis, the AGA suggests using therapies that have been approved for the treatment of ulcerative colitis, starting with topical mesalamine or topical corticosteroids. The panel also proposed key implementation considerations for optimal management of pouchitis and Crohn's-like disease of the pouch and identified several knowledge gaps and areas for future research.

CONCLUSIONS

This guideline provides a comprehensive, patient-centered approach to the management of patients with pouchitis and other inflammatory conditions of the pouch.

Clinical Case-Conference Blogs: Integrating Clinical Librarians to Enhance Resident Education and Enforce ACGME Competencies

Resident conferences are primary educational endeavors for trainees and faculty alike. We describe the development of collaborative clinician-librarian educational blogs within the Internal Medicine (2009), Pediatrics (2012), and General Surgery (2018) residency programs. Clinical librarians attended resident conferences and generated evidence-based blog posts based on learning topics and clinical questions encountered during the conferences. In the decade since introduction of the blogs, this partnership has resulted in over 2000 blog posts and generated over 1800 individual views per month. The development of a clinical librarian-managed blog serves as a relevant resource for promoting evidence-based practices within a case-based learning curriculum, engages interdisciplinary collaboration through existing resources, and is generalizable across various clinical practice disciplines and trainees.

Slow on the Uptake, Progression to Heartbreak

The prevalence of serotonin syndrome increases over the past several years as more serotonergic medications are being used in clinical practice. It is a potentially lethal condition caused by excessive serotonergic activity. Common causes of serotonin syndrome are the use of prescription medications, illicit drugs, or a combination of substances, leading to an increase in the activity of serotonin in the central and peripheral nervous system. The clinical symptoms range from mild to severe. We report a case of a 25-year-old woman with polysubstance abuse, including cocaine, who presented with confusion, rigidity, high-grade fever, and reduced biventricular function on echocardiogram. Based on the combination of substance used history, clinical presentation, and echocardiogram findings, she was diagnosed with serotonin syndrome complicated by takotsubo cardiomyopathy. She improved after being treated in the intensive care unit and was discharged from the hospital. This patient demonstrates the importance of recognizing and promptly initiating management of serotonin syndrome in order to improve morbidity and mortality.

Development of Hepatic Steatosis After Chemotherapy for Non-Hodgkin Lymphoma

Nonalcoholic fatty liver disease is the most common liver disorder in the developed world. Although typically reflecting caloric overload, it can also be secondary to drug toxicity. We aimed to describe the incidence and risk factors for de novo steatosis during chemotherapy for non‐Hodgkin lymphoma (NHL). In this retrospective case‐control study, adult patients with NHL were treated with rituximab, cyclophosphamide, doxorubicin, prednisone, and vincristine (R‐CHOP) or R‐CHOP + etoposide (EPOCH‐R). Patients with liver disease or steatosis were excluded. Abdominal computed tomography was performed pretreatment and at 3‐ to 6‐month intervals and reviewed for steatosis. Patients with de novo steatosis were matched 1:1 to controls by age, sex, and ethnicity. Of 251 treated patients (median follow‐up 53 months), 25 (10%) developed de novo steatosis, with the vast majority (23 of 25; 92%) developing it after chemotherapy. Of those, 14 (61%) developed steatosis within the first 18 months posttreatment and 20 (87%) within 36 months. Cases had higher baseline body mass index (BMI; mean ± SD, 29.0 ± 6.5 versus 26.0 ± 5.2 kg/m²; P = 0.014) and hyperlipidemia (12% versus 2%; P = 0.035). Although their weights did not change during chemotherapy, BMI in cases increased by 2.4 ± 2 kg/m² (mean ± SD) from end of treatment to steatosis compared to 0.68 ± 1.4 in controls (P = 0.003). Etoposide‐containing regimens were associated with a shorter time to steatosis (median 34 weeks versus 154 weeks; P < 0.001) despite similar baseline risk factors. Conclusion: The recovery period from NHL chemotherapy appears to be a “hot spot” for development of fatty liver, driven by early posttreatment weight gain, especially in subjects with baseline risk factors.

Encouraging Student Interest in Teaching Through a Medical Student Teaching Competition

PROBLEM

Clinician educators have realized the value not only of assigning teaching roles to medical students but also of offering explicit training in how to teach effectively. Despite this interest in the development of medical students' teaching skills, formal teaching instruction and opportunities for practice are lacking.

APPROACH

To encourage medical student interest in teaching, the authors developed and implemented a medical student teaching competition (MSTC) at Emory University School of Medicine during the summers of 2014, 2015, and 2016. Each year, eight student finalists were each paired with a physician "teaching coach" and given one month to prepare for the MSTC. During the competition, each finalist delivered an eight-minute presentation to a panel of seven physician and resident judges. The authors describe the development, implementation, and assessment of the MSTC.

OUTCOMES

Approximately 150 medical students and faculty members attended the MSTC each year. The students in attendance felt that the MSTC made them more likely to seek out opportunities to learn how to teach effectively and to practice teaching. Additionally, some students are now more interested in learning about a career in academic medicine than they were before the MSTC.

NEXT STEPS

Given the need for more formal initiatives dedicated to improving the teaching skills of doctors-in-training, including medical students, innovative solutions such as the MSTC may enhance a medical school's existing curriculum and encourage student interest in teaching. The MSTC model may be generalizable to other medical schools.

Fecal microbiota transplant for Clostridium difficile infection in older adults

BACKGROUND

The objective of this study was to describe the safety of fecal microbiota transplant (FMT) for Clostridium difficile infection (CDI) among older adults.

METHODS

We performed a case review of all FMT recipients aged 65 or older treated at Emory University Hospital, a tertiary care and referral center for Georgia and surrounding states.

RESULTS

CDI resolved in 27 (87%) of 31 respondents, including three individuals who received multiple FMTs. Among four whose CDI was not resolved at follow up, three respondents did well initially before CDI recurred, and one individual never eradicated his CDI despite repeating FMT. During the study, five deaths and eight serious adverse events requiring hospitalization were reported within the study group during the follow-up period. Fecal transplant was not a causative factor in these events. The most common adverse event reported in 4 (13%) of 31 respondents was subjective worsening of arthritis.

CONCLUSION

FMT is a generally safe and effective treatment option for older adults with CDI.

Alkynoate synthesis through the vinylogous reactivity of rhodium(II) carbenoids

Siloxy group migration: A rhodium(II) carbenoid approach has been developed for the synthesis of alkynoates. This transformation combines the addition of enol ethers at the vinylogous position of β-siloxy-substituted vinyldiazo derivatives with a siloxy group migration to give the products as single diastereomers.
