Background: Case reports describe the use of oral vancomycin therapy (OVT) in adult patients with concomitant symptomatic inflammatory bowel disease (IBD) and primary sclerosing cholangitis (PSC). OVT is associated with a higher likelihood of IBD remission in pediatric IBD-PSC patients. However, there are limited data on the association between OVT and IBD disease course in adult IBD-PSC patients.

Methods: We retrospectively evaluated IBD therapy intensification in adults with IBD-PSC prescribed OVT at 2 centers. Subjects were stratified by time "on" and "off" OVT. Only those who spent a minimum of 12 months in each period were included. The primary outcome was the frequency of IBD therapy intensification events.

Results: Of 31 patients initially considered, 22 met the inclusion criteria. Most patients (68.2%) had fewer or no intensification events while "on OVT" compared to those "off OVT". OVT was associated with fewer therapy intensification events (1.7 vs. 6.7, P=0.021) and steroid prescriptions (0.6 vs. 3.2, P=0.013) per 10 person-years.

Conclusions: OVT use is associated with less need for IBD therapy intensification in symptomatic IBD-PSC adult patients. Prospective trials of OVT in such patients are warranted.

The development of clinically significant portal hypertension (CSPH) represents one of the strongest predictive biomarkers for disease progression in patients with compensated advanced chronic liver disease (cACLD). Chronic liver injury triggers both intra- and extrahepatic mechanisms, giving rise to an increasing portal pressure and a self-perpetuating cycle with worsening risks of liver-related complications and mortality. Diagnosing CSPH becomes challenging in patients with advanced but compensated chronic liver disease where CSPH is not apparent clinically. Approximately 60% of patients with cACLD will have CSPH, representing a critical window for intervention to reduce portal pressure and prevent complications. The current gold standard for portal pressure measurement, the hepatic venous pressure gradient, is impractical for widespread use. Emerging diagnostic tools aim to address this limitation. Techniques such as endoscopic ultrasound-guided portal pressure gradient measurement, and noninvasive approaches using imaging methods, elastography (targeting liver and/or spleen) and serum markers, offer alternatives for CSPH detection, and moreover, can guide treatment decisions. Non-selective beta-blockers are known to reduce morbidity and mortality in patients with CSPH. Unfortunately, they remain the only approved therapy for CSPH and they are not effective in reducing portal pressure in all patients, highlighting the urgent need for additional therapeutic options as well as practical methods to evaluate treatment response. Recent innovations and ongoing research are steering the field toward a more personalized approach, where diagnosis, treatment and follow up are tailored to individual patient risk profiles. This evolution holds the potential to improve outcomes in patients with CSPH.

Background: Severe sepsis with septic shock (SSWSS) is a potential and severe complication that can arise among patients hospitalized for acute biliary pancreatitis.

Methods: We queried the 2018-2021 National Inpatient Sample for adults with a primary diagnosis code of acute biliary pancreatitis without necrosis or infection. Baseline characteristics of the patients were studied and multivariate regression models were used to appraise the roles of different factors for events of SSWSS.

Results: We evaluated 136,140 adults who had acute biliary pancreatitis without necrosis or infection on admission; their median age was 57.0 years, and the majority were female (60.6%). Of these, 435 patients developed SSWSS. Higher odds were seen in cases with coexisting chronic kidney disease (P<0.001), liver cirrhosis (P<0.001), and human immunodeficiency virus infection (P<0.001). Races other than White/Black/Hispanics had higher odds (P<0.001) than Whites. Females were less likely to report SSWSS (P<0.001) than males. Moreover, patients from the 26^th-50^th median household quartiles had lower odds of SSWSS than those in the 0-25^th quartiles. Medium (P<0.001) and large (P<0.001) hospitals reported more cases than small hospitals. Admissions in the southern areas of the United States also exhibited higher odds (P=0.026), than Northeast regions. Lower odds were noted in smokers (P<0.001) and cases with dyslipidemia (P=0.048). SSWSS led to higher mortality rates (65.5% vs. 0.4%).

Conclusions: In our nationwide analysis, we found that episodes of SSWSS among patients with acute biliary pancreatitis were influenced by several factors. SSWSS patients also had higher mortality.

Background: Irritable bowel syndrome (IBS) treatment relies on a low level of evidence. In this systematic review with meta-analysis of randomized, double-blind, placebo-controlled trials we assessed the efficacy of antidepressants in IBS.

Methods: This study followed the PRISMA guidelines and was registered in the PROSPERO database (CRD42024502427). PubMed, EMBASE and the Cochrane Library were searched from inception to January 2024. Only randomized, double-blind, placebo-controlled trials were included. Quality of evidence was assessed using the Cochrane tool (RoB 2). A random-effects model was used. Heterogeneity was evaluated by the I ² statistic and publication bias by funnel plots and the Egger test.

Results: The search strategy identified 1340 studies, of which 20 were included in the systematic review and 16 in the meta-analysis, totaling 1428 patients. The meta-analysis unveiled the efficacy of antidepressants in patients with IBS in overall symptom improvement (odds ratio [OR] 3.02; 95% confidence interval [CI] 2.16-4.2). Subgroup analysis revealed similar results regarding the efficacy of tricyclic antidepressants (OR 3.39, 95%CI 2.24-5.12); of selective serotonin reuptake inhibitors (OR 2.39, 95%CI 1.14-5.01); in patients refractory to first-line measures (OR 2.96, 95%CI 1.67-5.25); in patients without known comorbid psychological conditions (OR 2.92, 95%CI 1.6-5.31); and in the improvement in abdominal pain (OR 3.27, 95%CI 1.63-6.53), and bloating (OR 2.4, 95%CI 1.11-5.22). Publication bias was detected, and potential sources were identified. Sub-analysis without these sources of bias revealed similar results.

Conclusions: Antidepressants demonstrate efficacy in IBS. These medications can be beneficial to patients resistant to initial treatments and those lacking psychopathological symptoms.

Background: Helicobacter pylori (H. pylori) is a known risk factor for gastric cancer, possibly via the PD-1/L1 pathway, and this infection may reduce the efficacy of immune checkpoint inhibitors (ICIs). This study explored the effects of H. pylori infection status on survival outcomes in patients with gastric cancer.

Methods: This single-center, retrospective study included patients with gastric adenocarcinoma between June 1985 and August 2022. Patients with different histological subtypes were excluded. Primary variables of interest included H. pylori infection status and treatment with ICIs. Other clinical information included demographics, cancer histology, the presence of other cancers, and vital status.

Results: A total of 2930 patients were included, of whom 206 (7.0%) received ICIs, 196 (6.7%) had prior H. pylori infection, and 1037 (35.4%) had a diffuse subtype. Diffuse cancer subtypes were associated with better survival (P<0.05) at 3 and 5 years compared to intestinal-type adenocarcinomas. Diffuse cancers demonstrated better survival outcomes than intestinal cancers at 10 years, but only among H. pylori-positive patients (P=0.013). H. pylori positivity was associated with worse survival at 3 years (P=0.041) among patients taking ICIs, but not in those not receiving ICIs (P=0.325).

Conclusions: These findings suggest H. pylori infection may be an obstacle to successful immunotherapy, and may interact with cancer subtypes to differentially impact survival. Future studies are needed to validate the potential prognostic value of H. pylori positivity in gastric cancer.

Background: Duodenal biopsies are standard for diagnosing celiac disease (CD), but a biopsy-free approach has gained attention in the past decade. Evidence suggests that immunoglobulin A anti-tissue transglutaminase (IgA tTg) antibody levels ≥10 times the upper limit of normal (ULN) may reduce the need for histology. This study aimed to assess whether IgA tTg antibody titers ≥10 × ULN correlate with the histological diagnosis in adults.

Methods: The retrospective study was conducted at Mater Dei Hospital, Malta, analyzing adult patients who underwent upper gastrointestinal endoscopy with duodenal biopsies between 2012 and 2024. Data on demographics, symptoms, risk factors, serology and histological results were collected. Patients who had positive serology but initial negative biopsies and underwent repeat biopsies were also reviewed.

Results: Of 114 patients (78.1% female, mean age 41.0 years), 97.4% tested positive for IgA tTg antibodies and 93.8% for endomysial antibodies (EMA). CD was histologically confirmed in 70.2%, with females more frequently diagnosed than males (75.3% vs. 52%, P=0.025). CD-related symptoms were reported by 79.8%, while 20.2% were asymptomatic. Levels of tTg ≥10 × ULN were found in 41.2% patients, and this cutoff had a sensitivity of 58.8%, specificity of 100%, positive predictive value of 100% and negative predictive value of 50.7% for CD (P<0.001).

Conclusion: This study supports a biopsy-free approach for diagnosing CD when IgA tTg levels are ≥10 x ULN, especially with EMA positivity and typical clinical presentation.

Background: Endoscopic retrograde cholangiopancreatography (ERCP) is a critical tool in managing hepatobiliary and pancreatic diseases. Atrial fibrillation (AF) has been associated with greater morbidity in patients undergoing ERCP. This study compared in-hospital ERCP outcomes in patients with and without AF.

Methods: This retrospective cohort study utilized data from the National Inpatient Sample (2016-2020). Patients who underwent ERCP during hospitalization were included. Patients with AF were matched 1:1 to those without AF, based on demographic and clinical variables. The primary outcome was all-cause in-hospital mortality. Secondary outcomes included procedure-related and non-procedure-related complications, hospitalization cost and length of stay.

Results: The final matched sample consisted of 29,942 patients, with 14,971 in each group (AF and non-AF). Patients with AF demonstrated significantly higher in-hospital mortality compared to those without AF (3.6% vs. 1.9%; odds ratio [OR] 1.87, 95% confidence interval [CI] 1.62-2.17). The AF group had a significantly longer median length of stay (8.1 vs. 6.4 days; β 1.7; 95%CI 1.5-1.8) and incurred higher hospitalization costs ($111,000 vs. $87,255; β $23,745; 95%CI $20,783-26,708). In terms of complications, patients with AF had significantly higher rates of acute kidney injury (OR 1.33, 95%CI 1.27-1.40) and sepsis (OR 1.38, 95%CI 1.30-1.48). However, the rates of procedure-specific complications, including biliary perforation, post-ERCP pancreatitis and post-ERCP cholangitis, were similar between the 2 groups.

Conclusion: Patients with AF undergoing ERCP have higher in-hospital mortality, longer stays, greater costs, and higher rates of acute kidney injury and sepsis, although procedure-specific complication rates remain unaffected.

Background: Angiotensin-converting enzyme inhibitor-induced bowel angioedema (ACEi-IAE) is a rare and frequently under-recognized condition. Its nonspecific gastrointestinal symptoms could lead to missed diagnoses, unnecessary procedures and inappropriate treatments. Given the scarcity of studies, we conducted a systematic review to summarize the clinical characteristics of ACEi-IAE, the diagnostic approach and factors predicting delayed recovery.

Methods: Electronic databases, including MEDLINE, OVID and EMBASE, were used to identified eligible studies from inception to November 2024. Eligible cases were required to have a clear diagnosis of ACEi-IAE. Kaplan-Meier and multivariate Cox regression analyses were used to identify factors associated with delayed recovery time.

Results: Our systematic review included 81 eligible studies, comprising 117 ACEi-IAE cases with a mean age of 50 years, of which 83% were female. Patients were mainly African Americans (50%) taking lisinopril (71%). All patients (100%) presented with abdominal pain and other non-specific features. The median recovery time was 48 h after discontinuing ACEi. Patients who had been taking lisinopril for a longer than average period (25.9 months) had a statistically significantly lower hazard ratio for recovery (adjusted hazard ratio [aHR] 0.39, 95% confidence interval [CI] 0.19-0.81; P=0.012), as did patients who had radiographic evidence of jejunal edema (aHR 0.29, 95%CI 0.11-0.74; P=0.010). Diagnostic criteria were proposed and summarized based on the findings.

Conclusions: Clinicians should be aware of ACEi-induced bowel angioedema, particularly in ACEi users with non-specific abdominal pain. Implementation of our proposed diagnostic criteria is recommended to prevent unnecessary investigation and inappropriate treatment.

Background: The efficacy of atezolizumab-bevacizumab in patients with hepatocellular carcinoma (HCC) has not been studied separately in cirrhotic and non-cirrhotic patients. Our aim was to evaluate the efficacy of atezolizumab-bevacizumab in these patients, in relation to baseline values of the neutrophil-to-lymphocyte ratio (NLR).

Methods: We divided 57 atezolizumab-bevacizumab-treated HCC patients according to baseline NLR (>3: NLR-H, ≤3: NLR-L) and studied overall survival (OS) and progression-free survival (PFS) in 4 groups: group A, non-cirrhotic/NLR-L; group B, non-cirrhotic/NLR-H; group C, cirrhotic/NLR-L; and group D, cirrhotic/NLR-H.

Results: The 4 groups were comparable except for etiology, ALBI grade, macrovascular invasion, Barcelona Clinic Liver Cancer stage and prior therapy. Median OS and PFS were 30, 10, 12 and 5 months, and 14, 4, 8 and 2 months, for groups A, B, C, D, respectively (P<0.001). By Cox regression, cirrhotic/NLR-H patients showed significantly worse OS and PFS. Cirrhotic/NLR-L patients had better OS (12 vs. 5 months, P=0.002) and PFS (8 vs. 2 months, P=0.028) compared to cirrhotic/NLR-H. NLR was significantly correlated with OS (P=0.015). Non-cirrhotic/NLR-L patients had better OS (30 vs. 10 months, P=0.006) and PFS (15 vs. 4 months, P=0.01) compared to non-cirrhotic/NLR-H patients. Prior therapy was significantly correlated with better OS (30 vs. 8 months, P<0.001) and PFS (24 vs. 4 months, P<0.001) in non-cirrhotic patients.

Conclusions: Cirrhotic/NLR-H HCC patients presented the worst survival. NLR is an independent risk factor for worse survival in cirrhotic patients. Prior therapy is the only factor significantly correlated with OS and PFS in non-cirrhotic patients.

Background: The main symptoms of gastroparesis are early satiety, nausea, vomiting and bloating. In our daily practice, we observed some patients presenting with concomitant chronic alteration of stool frequency. The present study describes retrospectively the impact of gastric peroral endoscopic myotomy (G-POEM) on patients presenting refractory gastroparesis and concomitant chronic diarrhea or constipation.

Methods: This retrospective study analyzed the clinical course of patients with refractory gastroparesis and concomitant chronic alteration of stool frequency who were consecutively treated with G-POEM between January 2019 and October 2023 in a tertiary referral center.

Results: Of 107 patients with refractory gastroparesis treated by G-POEM, 11 (10.3%) patients (mean age 60.4±16.2 years, 64% female) had altered bowel frequency for >6 months without any other underlying disease (diarrhea n=10; constipation n=1). Scintigraphy confirmed delayed gastric emptying in 10/11 (91%) of cases. G-POEM was technically feasible in all patients without adverse events during or after endoscopic treatment. The median follow-up period was 170 days (interquartile range [IQR] 33-1002). In 9/11 (81%) patients, G-POEM achieved clinical success with a mean gastroparesis cardinal symptom index (GCSI) of 3.1 (interquartile range [IQR] 2.7-3.4) before, and 0.9 (IQR 0.7-1.7) after the endoscopic treatment. Normalization of bowel movements after G-POEM was observed in 9/11 (81%) of patients. Two patients had partial symptom improvement (loose bowels, but normal frequency), 1 of them without improvement of GCSI and persistent delayed emptying on scintigraphy.

Conclusion: Gastroparesis may present with concomitant chronic diarrhea that improves after endoscopic treatment by G-POEM.
