Proactive Therapeutic Drug Monitoring of Ustekinumab Is Associated With Increased Drug Persistence in Patients With Inflammatory Bowel Disease.

BACKGROUND: There are limited data on the role of proactive therapeutic drug monitoring (TDM) of ustekinumab (UST) in patients with inflammatory bowel disease (IBD). This study investigated the efficacy and safety of proactive TDM in IBD patients treated with subcutaneous (sc) UST. METHODS: This was a retrospective single-center cohort study. Consecutive patients with IBD who received maintenance subcutaneous (sc) UST therapy and underwent TDM from January 2017 to February 2023 were eligible for inclusion. Patients were followed through May 2024 or until drug discontinuation or an IBD-related surgery. Patients underwent either at least one proactive TDM or reactive TDM only. Survival analysis was performed to evaluate drug persistence, defined as no need for drug discontinuation due to loss of response, serious adverse event (SAE) or an IBD-related surgery, and IBD-related hospitalizations. RESULTS: The study population consisted of 83 patients (proactive TDM, n = 46) of whom 67 (81%) had Crohn's disease. Patients who had at least one proactive TDM had higher drug persistence (Log-rank P < .001) and less IBD-related hospitalization (Log-rank P = .012) compared to patients undergoing only reactive TDM. In multivariable COX proportional hazard regression analysis, at least one proactive TDM was associated with increased drug persistence (hazard ratio [HR]: 5; 95% confidence interval [95% CI], 2-10; P < .001) and decreased IBD-related hospitalization (HR: 0.24; 95% CI, 0.07-0.83; P = .024). There was no SAE reported. CONCLUSIONS: This retrospective study showed that proactive TDM is associated with increased drug persistence and decreased IBD-related hospitalization in IBD patients treated with sc UST.

There is still limited information regarding the role of therapeutic drug monitoring (TDM) other than antitumor necrosis factor biologics. This study showed that proactive TDM is associated with increased drug persistence and decreased inflammatory bowel disease (IBD)-related hospitalization in patients with IBD treated with ustekinumab.

Patched but Still Leaky: An Update on the Pipeline for Women in Gastroenterology.

BACKGROUND: Women remain underrepresented in gastroenterology (GI). Studies have identified that a lack of formal mentorship for women contributes to this underrepresentation. While many GI divisions have adopted models for supporting GI fellows and faculty, there is a gap in our knowledge regarding mentorship options for internal medicine (IM) residents interested in GI. AIMS: To evaluate representation of women at each level of their career (resident, fellow, and attending) and examine trends in representation of women in GI compared to other IM subspecialties. METHODS: We analyzed AAMC Physician Specialty Data Reports to compare gender representation and growth of women representation across all IM subspecialties and residencies from 2007 to 2021. RESULTS: In 2021, 44.3% of IM residents, 37.8% of GI fellows, and 19.7% of actively practicing attending gastroenterologists were women. Since 2007, GI comprised significantly lower proportions of women attendings except for cardiology, and lower representation in fellows, except for cardiology and nephrology, than other IM subspecialties (p < 0.001). There was a consistently higher proportion of women GI fellows than attendings over the past 14 years (p < 0.01). CONCLUSIONS: GI has among the lowest representation of women at each career level compared to other IM subspecialties. Given the previously reported preference of gender congruent mentoring, the underrepresentation of senior academic gastroenterologists who are women may be a contributing factor to lower proportions of women trainees choosing to pursue GI.

Proactive Therapeutic Drug Monitoring Is Associated With Increased Drug Persistence in Patients With Inflammatory Bowel Disease Treated With Intravenous Vedolizumab.

BACKGROUND: There are limited data regarding therapeutic drug monitoring (TDM) of non-anti-tumor necrosis factor therapy in inflammatory bowel disease (IBD). This study aimed to evaluate the efficacy of proactive TDM in IBD patients treated with intravenous (iv) vedolizumab (VDZ). METHODS: This single-center retrospective cohort study included consecutive IBD patients treated with maintenance iv VDZ therapy undergoing TDM from November 2016 to March 2023. Patients were followed through June 2023 and were divided in to 2 groups: those who had at least 1 proactive TDM vs those who underwent only reactive TDM. A survival analysis was performed to evaluate drug persistence, defined as no need for drug discontinuation due to loss of response, serious adverse event, or an IBD-related surgery. RESULTS: The study population consisted of 94 patients (proactive TDM, n = 72) with IBD (ulcerative colitis, n = 53). Patients undergoing at least 1 proactive TDM compared with patients having only reactive TDM demonstrated a higher cumulative probability of drug persistence (Log-rank P < .001). In multivariable Cox proportional hazard regression analysis, at least 1 proactive TDM was the only factor associated with drug persistence (hazard ratio, 14.3; 95% confidence interval [CI], 3.8-50; P < .001). A ROC analysis identified a VDZ concentration of 12.5 µg/mL as the optimal drug concentration threshold associated with drug persistence (area under the ROC curve: 0.691; 95% CI, 0.517-0.865; P = .049). CONCLUSION: In this single-center retrospective study reflecting real-life clinical practice, proactive TDM was associated with increased drug persistence in patients with IBD treated with iv VDZ.

There are limited data regarding therapeutic drug monitoring (TDM) of non-anti-tumor necrosis factor therapy in inflammatory bowel disease (IBD). We found that proactive TDM was associated with drug persistence in patients with IBD treated with vedolizumab. Moreover, a vedolizumab concentration of 12.5 µg/mL was identified as the optimal drug concentration threshold associated with drug persistence.

Sweet or Not? Azathioprine-Induced Sweet Syndrome Mimicking Erythema Nodosum in a Patient With Inflammatory Bowel Disease.

This case report highlights the clinical challenge and need to distinguish Sweet syndrome and erythema nodosum (EN) in a 50-year-old woman with newly initiated azathioprine for inflammatory bowel disease. While she initially presented with clinical features concerning for drug-induced Sweet syndrome, a subsequent histopathological examination confirmed early-stage EN. Both Sweet syndrome and EN share common triggers and therapeutic responses, but have distinctive clinical characteristics. Subtle histologic differences also exist in lesion distribution and depth of infiltration. This case underscores the need for accurate differentiation in patients with inflammatory bowel disease to initiate appropriate management and avoid potential complications.

Impact of Geospatial Food Access on Acute Pancreatitis Outcomes.

BACKGROUND AND AIM: Food access is an important social determinant of health and refers to geographical and infrastructural aspects of food availability. Using publicly available data on food access from the United States Department of Agriculture (USDA), geospatial analyses can identify regions with variable food access, which may impact acute pancreatitis (AP), an acute inflammatory condition characterized by unpredictable outcomes and substantial mortality. This study aimed to investigate the association of clinical outcomes in patients with AP with geospatial food access. METHODS: We examined AP-related hospitalizations at a tertiary center from January 2008 to December 2018. The physical addresses were geocoded through ArcGIS Pro2.7.0 (ESRI, Redlands, CA). USDA Food Access Research Atlas defined low food access as urban areas with 33% or more of the population residing over one mile from the nearest food source. Regression analyses enabled assessment of the association between AP outcomes and food access. RESULTS: The study included 772 unique patients with AP residing in Massachusetts with 931 AP-related hospitalizations. One hundred and ninety-eight (25.6%) patients resided in census tracts with normal urban food access and 574 (74.4%) patients resided in tracts with low food access. AP severity per revised Atlanta classification [OR 1.88 (95%CI 1.21-2.92); p = 0.005], and 30-day AP-related readmission [OR 1.78(95%CI 1.11-2.86); p = 0.02] had significant association with food access, despite adjustment for demographics, healthcare behaviors, and comorbidities (Charlson Comorbidity Index). However, food access lacked significant association with AP-related mortality (p = 0.40) and length of stay (LOS: p = 0.99). CONCLUSION: Low food access had a significant association with 30-day AP-related readmissions and AP severity. However, mortality and LOS lacked significant association with food access. The association between nutrition, lifestyle, and AP outcomes warrants further prospective investigation.

Disparities in race, ethnicity, sex, and age inclusion in pancreatic cancer screening studies: a systematic review and meta-analysis.

BACKGROUND AND AIMS: Substantial differences exist in pancreatic cancer outcomes across ethnoracial stratifications. We sought to assess racial, ethnic, sex, and age reporting and inclusion of participants in pancreatic cancer screening studies. METHODS: A systematic search of Cochrane Library, Ovid Embase, Google Scholar, Ovid MEDLINE, PubMed, Scopus, and Web of Science Core Collection from inception to 2022 was conducted. Original studies on pancreatic cancer screening were identified and assessed for reporting and inclusion on race, ethnicity, sex, and age. The pooled proportions of study participants for these characteristics were calculated and compared with population-based benchmarks. RESULTS: Among 27 eligible pancreatic cancer screening studies, 26 reported data on either sex, race, or ethnicity, with a total of 5273 participants. Information on participant sex was reported by 26, race by 12, and ethnicity by 8 studies. Participants in these studies were almost all white (pooled proportion, 93.1%; 95% confidence interval [CI], 89.7-96.4) and non-Latino (pooled proportion, 97.4%; 95% CI, 94.0-100), and these groups were over-represented when compared with the general population. Female participants were well represented, with a pooled proportion of 63.2% (95% CI, 59.9-66.6). When reported, mean or median participant age was <60 years. Meta-regression revealed higher proportions of female participants in studies from the United States (P = .002). No association between increasing participation of racial or ethnic under-represented populations and study quality, ascending year of publication, or source of study funding was noted. CONCLUSIONS: Substantial disparities in race, ethnicity, sex, and age reporting and inclusion in pancreatic cancer studies were noted, even among high-quality and publicly funded studies.

Sexual Health in Sexual and Gender Minority Patients with Inflammatory Bowel Disease.

BACKGROUND: In recent years, legislation targeting the sexual and gender minority (SGM) community has been passed at an increasingly alarming rate, affecting access to safe and effective gender-affirming care and forcing many SGM patients, including those with inflammatory bowel disease (IBD), to withhold their identities and health concerns. Additionally, SGM patients with IBD may have unique health considerations that have not yet been well-studied OBJECTIVE: This article aims to explore the intersection of IBD and sexual health in patients who identify as SGM and to identify limitations for gastroenterologists in caring for SGM patients. The article also aims to provide suggestions for improvement in SGM-competent care within gastroenterology METHODS: A thorough literature review was conducted regarding sexual health and the SGM community with IBD. This included a review of surgical considerations in SGM patients, sexually transmitted infections (STIs) and prevention, and sexual dysfunction RESULTS: Overall, little is known about the impact of IBD on patients who identify as sexual and gender minorities. Surgery, medications, and STIs continue to be a concern in the SGM community with IBD and these areas represent opportunities to improve SGM-competent IBD care. Additionally, implementation of an SGM-focused curriculum is urgently needed in medical education to improve provider knowledge and care for this unique group of patients CONCLUSIONS: Patients with IBD who identify as SGM experience challenges that are not well described in prior literature. More research is needed and is actively being pursued to guide provider awareness and improve sexual health for this patient population.

Sex differences impact ergonomic endoscopic training for gastroenterology fellows.

BACKGROUND AND AIMS: Endoscopic-related injuries (ERIs) for gastroenterologists are common and can impact longevity of an endoscopic career. This study examines sex differences in the prevalence of ERIs and ergonomic training during gastroenterology fellowship. METHODS: A 56-item anonymous survey was sent to 709 general and advanced endoscopy gastroenterology fellows at 73 U.S. training programs between May and June 2022. Demographic information was collected along with questions related to endoscopic environment, ergonomic instruction, technique, equipment availability, and ergonomic knowledge. Responses of female and male gastroenterology fellows were compared using χ2 and Fisher exact tests. RESULTS: Of the 236 respondents (response rate, 33.9%), 113 (44.5%) were women and 123 (52.1%) were men. Female fellows reported on average smaller hand sizes and shorter heights. More female fellows reported endoscopic equipment was not ergonomically optimized for their use. Additionally, more female fellows voiced preference for same-gender teachers and access to dial extenders and well-fitting lead aprons. High rates of postendoscopy pain were reported by both sexes, with significantly more women experiencing neck and shoulder pain. Trainees of both sexes demonstrated poor ergonomic awareness with an average score of 68% on a 5-point knowledge-based assessment. CONCLUSIONS: Physical differences exist between male and female trainees, and current endoscopic equipment may not be optimized for smaller hand sizes. This study highlights the urgent need for formal ergonomic training for trainees and trainers with consideration of stature and hand size to enhance safety, comfort, and equity in the training and practice of endoscopy.

Hyperbilirubinemia in a Patient With Sepsis: A Diagnostic Challenge.

Cholestasis due to sepsis is commonly seen in critically ill patients; however, it is often overlooked and poses a challenge in clinical diagnosis and management. In this report, we present a 29-year-old woman who presented to the emergency department with jaundice and symptoms of a urinary tract infection. Initially suspected to be Dubin-Johnson syndrome, sepsis-induced cholestasis was eventually diagnosed after testing. Sepsis should always be considered as part of the differential diagnosis while managing a patient with jaundice. The management of sepsis-induced cholestasis involves treating the underlying infection. In most cases, liver injury improves with the resolution of the infectious process.

High Prevalence of Malnutrition and Micronutrient Deficiencies in Patients With Inflammatory Bowel Disease Early in Disease Course.

BACKGROUND: Patients with inflammatory bowel disease (IBD) are at an increased risk of malnutrition. The goal of this study was to define the prevalence of malnutrition and micronutrient deficiencies in recently diagnosed IBD patients and to compare the performance of existing malnutrition screening tools in identifying IBD patients at increased risk for malnutrition. METHODS: This was a retrospective cohort study of adult patients with recently diagnosed IBD (≤18 months disease duration). A diagnosis of malnutrition was made utilizing the European Society for Clinical Nutrition and Metabolism malnutrition criteria. Serum micronutrient levels were included. The sensitivity of 5 malnutrition screening tools in identifying patients at moderate-high risk of malnutrition was determined based on the European Society for Clinical Nutrition and Metabolism malnutrition definition. Descriptive statistics summarized the data and univariate analyses tested associations. RESULTS: A total of 182 patients were included for analysis; 65 (36%) met criteria for malnutrition. A total of 135 (74%) patients had ≥1 micronutrient level checked and 105 (78%) had ≥1 deficiency. Patients with prior surgery (odds ratio [OR], 4.5; P = .004), active Crohn's disease (OR, 2.8; P = .03), and diarrhea (OR, 2.1; P = .02) were more likely to be malnourished. The Malnutrition Universal Screening Tool and Saskatchewan IBD Nutrition Risk Tool had the highest sensitivity (100%) in predicting those at moderate-high risk of malnutrition at the time of screening. CONCLUSIONS: Patients with recently diagnosed IBD have a high prevalence of malnutrition and micronutrient deficiencies. Both the Malnutrition Universal Screening Tool and Saskatchewan IBD Nutrition Risk Tool can be used to identify those at increased risk of malnutrition. Future studies and screening tool development are necessary to identify those at risk of developing malnutrition to facilitate timely referral for nutritional evaluation and prevent disease related complications.

This retrospective cohort study identified that patients with recently diagnosed inflammatory bowel disease have a high prevalence of malnutrition as well as micronutrient deficiencies and compared the utility of 5 available malnutrition screening tools in this population.

De Novo Ostomy Placement Is Associated with Increased Outpatient Opioid Use In Patients with Inflammatory Bowel Disease.

BACKGROUND/AIMS: Opioid use is associated with poor outcomes in patients with inflammatory bowel disease (IBD). We aimed to identify novel factors associated with increased outpatient opioid (OPRx) use following IBD-related hospitalization. METHODS: This was a retrospective cohort study of IBD patients ≥ 18 years old, hospitalized during 2018. The primary outcome was receiving ≥ 1(OPRx) in the year following index hospitalization (IH), excluding prescriptions written within 2 weeks of discharge. Secondary outcomes included having 1-2 vs ≥ 3 OPRx and rates of healthcare utilization. Univariate and multivariate analyses tested associations with OPRx. RESULTS: Of 526 patients analyzed, 209 (40%) received at least 1 OPRx; with a median of 2 [1-3] OPRx. Presence or placement of ostomy at IH, exposure to opioids during IH, ulcerative colitis (UC), mental health comorbidities, admission for surgery and managed on the surgical service, and IBD surgery within 1 year prior to IH were associated with ≥ 1 OPRx on univariate analysis. On multivariable analysis, UC, ostomy placement during IH, anxiety, and inpatient opioid exposure were independently associated with ≥ 1 OPRx. A majority (> 70%) of both inpatient and outpatient opioid prescriptions were written by surgeons. Patients requiring ≥ 3 OPRx had the highest rates of unplanned IBD surgery (56% p = 0.04), all-cause repeat hospitalization (81%, p = 0.003), and IBD-related repeat hospitalization (77%, p = 0.007) in the year following IH. CONCLUSIONS: A multimodal approach to pain management for IBD patients, as well as increased recognition that any patient with a de novo ostomy is at particular risk of opioid use, is needed.

Analysis of Speaker Introduction Formality by Gender at the American College of Gastroenterology 2020 Annual Scientific Meeting.

BACKGROUND: Gender-based differences in the use of professional titles during speaker introductions have been described in other medical specialties. AIMS: Our primary aim was to assess gender-based differences in the formality of speaker introductions at the American College of Gastroenterology 2020 Virtual Annual Scientific Meeting. Our secondary aim was to assess gender-based differences in the formality of speaker self-introductions. METHODS: Reviewed presentations from the American College of Gastroenterology Annual Meeting for gender-based differences in professional title use during speaker introductions and self-introductions. RESULTS: Speakers included 29 women (37.2%) and 49 men (62.8%). We found no significant gender differences in the use of professional titles by introducers (t(67) = - 0.775, p = 0.441) or in self-introductions (36.4% of women vs. 41.9% of men, t(63) = 0.422, p = 0.674). CONCLUSION: The lack of gender differences in professional title use may represent a novel advantage of virtual meeting formats or suggest increased attention to gender bias in introductions.
