Goals: We assessed satisfaction with and adherence to off-label corticosteroids in patients with eosinophilic esophagitis (EoE) in the United States.

Background: EoE is a chronic inflammatory disease for which there are currently no US Food and Drug Administration-approved swallowed topical corticosteroids.

Study: This noninterventional, cross-sectional, web-based survey included caregivers of adolescents (aged 11 to 17 y) and adults (aged 18 years or older) with a self-reported [or caregiver-reported (adolescents)] physician diagnosis of EoE who were receiving corticosteroids. Participants were recruited through 2 nonprofit, patient advocacy groups. The 9-item Treatment Satisfaction Questionnaire for Medication (TSQM-9) was used to assess satisfaction across effectiveness, convenience, and global satisfaction domains (scale: 1 to 100 per domain); higher scores indicated greater satisfaction. The 4-item Morisky Green Levine Medication Adherence Scale (MGL-4) was used to assess adherence; an MGL-4 score of <3 indicated adherence. Participants also reported reasons for nonadherence.

Results: Overall, 201 participants (caregivers of adolescents, n=98; adults, n=103) were included in this study. Mean TSQM-9 scores indicated low satisfaction with off-label corticosteroids across all 3 satisfaction domains in adolescents (≤61.1) and adults (≤55.7). Slightly fewer adolescents (37.1%) than adults (40.8%) were considered adherent. Forgetfulness was the most frequently reported reason for nonadherence; some patients chose not to take their medications, owing to poor palatability (adolescents), difficulty taking medications at specific times (adults), or feeling depressed/overwhelmed (adolescents and adults).

Conclusions: Satisfaction with and adherence to off-label corticosteroids were low in this web-based survey of adolescents and adults with EoE in the United States.

Background: Clinical guidelines reserve endoscopic surveillance after a gastric intestinal metaplasia (GIM) diagnosis for high-risk patients. However, it is unclear how closely guidelines are followed in clinical practice. We examined the effectiveness of a standardized protocol for the management of GIM among gastroenterologists at a US hospital.

Methods: This was a preintervention and postintervention study, which included developing a protocol and education of gastroenterologists on GIM management. For the preintervention study, 50 patients with GIM were randomly selected from a histopathology database at the Houston VA Hospital between January 2016 and December 2019. For the postintervention study, we assessed change in GIM management in a cohort of 50 patients with GIM between April 2020 and January 2021 and surveyed 10 gastroenterologists. The durability of the intervention was assessed in a cohort of 50 GIM patients diagnosed between April 2021 and July 2021.

Results: In the preintervention cohort, GIM location was specified (antrum and corpus separated) in 11 patients (22%), and Helicobacter pylori testing was recommended in 11 of 26 patients (42%) without previous testing. Gastric mapping biopsies were recommended in 14% and surveillance endoscopy in 2%. In the postintervention cohort, gastric biopsy location was specified in 45 patients (90%, P <0.001) and H. pylori testing was recommended in 26 of 27 patients without prior testing (96%, P <0.001). Because gastric biopsy location was known in 90% of patients ( P <0.001), gastric mapping was not necessary, and surveillance endoscopy was recommended in 42% ( P <0.001). One year after the intervention, all metrics remained elevated compared with the preintervention cohort.

Conclusions: GIM management guidelines are not consistently followed. A protocol for GIM management and education of gastroenterologists increased adherence to H. pylori testing and GIM surveillance recommendations.

Goal: The aim of this study was to evaluate the efficacy of supplementation with Agave tequilana Weber blue variety fructans (Predilife) in the improvement of symptoms in functional constipation.

Background: Fiber supplementation is the first-line treatment for constipation. Fibers-like fructans have a known prebiotic effect.

Materials and methods: A randomized, double-blind, study comparing agave fructans (AF) against psyllium plantago (PP). Four groups were randomized. Group 1: AF 5 g (Predilife), group 2: AF 10 g (Predilife), group 3: AF 5 g (Predilife)+10 g maltodextrin (MTDx), and group 4: PP 5 g+10 g MTDx. The fiber was administered once daily for 8 weeks. All fibers were similarly flavored and packaged. Patients kept their usual diet and fiber sources were quantified. Responders were defined as ≥1 complete spontaneous bowel movement from baseline to 8 weeks. Adverse events were reported. The study was registered in Clinicaltrials.gov with registration number NCT04716868.

Results: Seventy-nine patients were included (group 1: 21, group 2: 18, group 3: 20, and group 4: 20), of which 62 (78.4%) were women. The responders were similar across groups (73.3%, 71.4%, 70.6%, and 69%, P >0.050). After 8 weeks, all groups significantly increased complete spontaneous bowel movements, showing the greatest increase in spontaneous bowel movements in group 3 ( P =0.008). All groups improved in symptoms, stool consistency, and quality of life. Diet and fiber intake were similar between groups. Adverse events were mild and similar between groups.

Conclusions: AF (Predilife) are as effective at different doses and combined with MTDx as PP and are a feasible option for the treatment of functional constipation.

Background: Hepatic fibrosis and secondary biliary cirrhosis are consequences of long-standing benign biliary strictures. Evidence on the reversibility of fibrosis after the repair is incongruous.

Methodology: A prospective observational study on patients who underwent Roux-en-Y hepaticojejunostomy for benign biliary stricture. A liver biopsy was performed during repair and correlated with preoperative elastography. The improvement in liver functions and regression of fibrosis was compared with preoperative liver function tests and elastography.

Results: A Total of 47 patients [mean age-38.9 y (Range: 21 to 66)] with iatrogenic benign biliary stricture were included. A strong female preponderance was noted. High strictures (type III and IV) comprised 72.7% of the study group. The median interval (injury to repair) was 7 months (2 to 72 mo). The median duration of jaundice was 3 months (1 to 20 mo). Both factors had a significant correlation with the stage of fibrosis ( P =0.001 and P =0.03, respectively). Liver biopsy revealed stage I, II, III, and IV fibrosis in 26 (55.3%), 11 (23.4%), 2 (4.3%), and 2(4.3%), respectively. The remaining 6 (12.8%) had no fibrosis. The severity of fibrosis had a good correlation with preoperative liver stiffness measurement-value on FibroScan. Significant improvement in liver function tests (bilirubin-3.55±3.48 vs. 0.59±0.52; Albumin-3.85±0.61 vs. 4.14±0.37; ALP-507.66±300.65 vs. 167±132.07; P value 0.00) and regression of fibrosis (liver stiffness measurement; 10.42±5.91 vs. 5.85±3.01, P value 0.00) was observed after repair of the strictures.

Conclusion: Improved biliary function and regression of liver fibrosis can be achieved with timely repair of benign biliary stricture and it is feasible to be evaluated using elastography.

Background and aims: When endoscopic retrograde cholangiopancreatography-guided biliary drainage is challenging, endoscopic ultrasound-guided biliary drainage (EUS-BD) can be used as an alternate treatment; however, this method requires operator expertise. Therefore, this study aimed to clarify the factors that are associated with a difficult EUS-BD.

Patients and methods: Patients who successfully underwent EUS-BD were enrolled in this study. The patients were divided into the easy group and difficult group depending on whether the procedural time was more than 60 minutes, which was the cutoff value elicited from past reports. Patient characteristics and procedural factors were compared between the two groups. The factors associated with difficult procedures were also investigated.

Results: The patient characteristics were not significantly different between the easy group (n=22) and the difficult group (n=19). The diameter of the punctured bile duct was significantly different between the two groups. In the multivariate analysis, the diameter of the punctured bile duct was the only factor associated with a difficult EUS-BD (odds ratio 0.65, 95% confidence interval 0.46-0.91, P value=0.012). The cutoff value for the diameter of the punctured bile duct in predicting a difficult EUS-BD was 7.0 mm (area under the curve: 0.83, sensitivity 84.2%, specificity 86.4%).

Conclusions: A nondilated bile duct might be a predictive factor for a difficult EUS-BD. For beginners of EUS-BD, the cutoff value for the punctured bile duct diameter found in this study, 7.0 mm, might become a barometer for puncture point selection.

Goals: We aim to explore the relationship between the use of proton pump inhibitors (PPIs) and upper gastrointestinal bleeding (UGIB). We develop a nomogram model to predict mortality in critically ill stroke patients.

Study: This is a retrospective study based on the MIMIC IV database. We extracted clinical information including demographic data, comorbidities, and laboratory indicators. Univariate and multivariable logistic regressions were used to assess and identify risk factors for the occurrence of UGIB and for the in-hospital mortality of critically ill stroke patients. The resulting model was used to construct a nomogram for predicting in-hospital mortality.

Results: Five thousand seven hundred sixteen patients from the MIMIC-IV database were included in our analysis. UGIB occurred in 109 patients (1.9%), whereas the PPI use rate was as high as 60.6%. Chronic liver disease, sepsis, shock, anemia, and increased level of urea nitrogen were independent risk factors for the occurrence of UGIB in severe stroke patients. We identified age, heart failure, shock, coagulopathy, mechanical ventilation, continuous renal replacement therapy, antiplatelet drugs, anticoagulation, simplified acute physiology score-II, and Glasgow coma score as independent risk factors for in-hospital mortality in severe stroke patients. The C-index for the final nomograms was 0.852 (95% confidence interval: 0.840, 0.864).

Conclusions: We found that the overall rate of UGIB in severe stroke patients is low, whereas the rate of PPI usage is high. In our study, PPI was not identified as a risk factor for the occurrence of UGIB and UGIB was not associated with all-cause mortality. More clinical trials are needed to evaluate the benefits of using PPI in critically ill stroke patients.

Goals: We analyzed if the predictive value of multitarget stool-based DNA (mt-sDNA) varied when patients had pre-existing known colorectal cancer (CRC) risk factors.

Background: mt-sDNA test is approved for CRC screening in average-risk patients. Whether patients with a personal history of adenomatous colon polyps or a family history of CRC (CRC risk factors) benefit from mt-sDNA testing is unknown.

Study: We reviewed charts for all positive mt-sDNA referrals between 2017 and 2021. Diagnostic colonoscopy adherence rates were calculated. In those who had colonoscopy, we compared detection rates for any colorectal neoplasia (CRN), multiple (3 or more) adenomas, sessile serrated polyps (SSP), advanced CRN, and CRC between patients with and without known CRC risk factors.

Results: Of 1297 referrals for positive mt-sDNA, 1176 (91%) completed a diagnostic colonoscopy. The absence of neoplasia was noted in 27% of colonoscopy exams. When neoplasia was identified, findings were as follows: any CRN (73%), multiple adenomas (34%), SSP (23%), advanced CRN (33%), and CRC (2.5%). One or more CRC risk factors were present in 229 (19%) of cases. In the CRC risk factor subgroup, patients having a prior history of adenomatous polyps or a family history of CRC were no more likely to have any CRN, multiple adenomas, SSP, advanced CRN, or CRC compared to average-risk patients when mt-sDNA was positive.

Conclusions: In this real-world analysis of positive mt-sDNA referrals, adherence to subsequent diagnostic colonoscopy recommendations was high. The presence of pre-existing CRC risk factors did not affect the positive predictive value of mt-sDNA.

Goals: This study aims to investigate associated mortality with inpatient endoscopic retrograde cholangiopancreatography (ERCP) with and without resistant infections. The co-primary objective compares frequencies of inpatient ERCP with resistant infections to overall hospitalizations with resistant infections.

Background: The risks of inpatient antibiotic-resistant organisms are known, but the associated mortality for inpatient ERCP is unknown. We aim to use a national database of hospitalizations and procedures to understand trends and mortality for patients with antibiotic-resistant infections during inpatient ERCP.

Study: The largest publicly available all-payer inpatient database in the United States (National Inpatient Sample) was used to identify hospitalizations associated with ERCPs and antibiotic-resistant infections for MRSA, VRE, ESBL, and MDRO. National estimates were generated, frequencies were compared across years, and multivariate regression for mortality was performed.

Results: From 2017 to 2020, national weighted estimates of 835,540 inpatient ERCPs were generated, and 11,440 ERCPs had coincident resistant infections. Overall resistant infection, MRSA, VRE, and MDRO identified at the same hospitalization of inpatient ERCPs were associated with higher mortality (OR CI(95%): Overall: 2.2(1.77-2.88), MRSA: 1.90 (1.34-2.69), VRE: 3.53 (2.16-5.76), and MDRO: 2.52 (1.39-4.55)). While overall hospitalizations with resistant infections have been decreasing annually, there has been a yearly increase in admissions requiring ERCPs with simultaneous resistant infections ( P =0.001-0.013), as well as infections with VRE, ESBL, and MDRO ( P =0.001-0.016). Required Research Practices for Studies Using the NIS scoring was 0, or the most optimal.

Conclusions: Inpatient ERCPs have increasing coincident resistant infections and are associated with higher mortality. These rising infections during ERCP highlight the importance of endoscopy suite protocols and endoscopic infection control devices.
