Introduction

Although Crohn’s disease (CD) patients are expected to be at high risk for developing NAFLD, because of their altered nutrition state and some CD medication, little is known about prevalence of this condition in this population.

Aims & Methods

The aim of our study was to describe the prevalence of hepatic steatosis and fibrosis in patients with Crohn's disease and to assess their risk factors.
This was a cross-sectional, descriptive study including patients with CD, diagnosed since at least one year. We excluded patients known to have chronic liver disease or a condition that could lead to it (chronic alcoholism, viral infection with hepatotropic viruses, portal thrombosis, etc.). Patients included were at least in clinical remission. Elastometry and Controlled Attenuation Parameter (CAP) measurement were made in all patients, using a fibroScan® with an XL probe. Data were collected and analyzed by SPSS software version 26.

Results

We included 100 patients, 55 men and 45 women with a mean age of 42 ± 12 years. Seven patients had diabetes and 4 had hypertension. Forty-one patients were smokers. The mean duration of CD was 11.09 years. The disease was ileal, colonic or ileocolic in 39%, 24% and 29% of cases respectively. An upper gastrointestinal tract’s involvement was observed in 7 patients and ano-perineal lesions was observed in 36 patients. The phenotype was inflammatory, stricturing and fistulizing in 55%, 21% and 24% of the patients respectively. Almost half of our patients (45%) had already received at least one course of corticosteroids. CAP measurement had shown S1, S2 and S3 stage steatosis in 8%, 3% and 7% of patients respectively. Factors associated with the presence of hepatic steatosis were diabetes (p=0.002, OR=15), presence of overweight or obesity (p=0.005, OR=4,71), age over 35 years at the time of study (p=0.038). ALT level greater than 10.75IU/L was also associated with the presence of hepatic steatosis (p=0.04). Several factors related to corticosteroid courses were associated with the presence of hepatic steatosis such as a duration shorter than 18 months since the last corticosteroid course (p=0.038), maximum achieved prednisolone dose of more than 55mg/d (p=0.04) and duration on full dose of corticosteroids exceeding 4.5 weeks (p=0.016). FibroScan® showed a fibrosis stage F1 in 4% and F2 in 7%. Elasticity in the remaining patients was less than 6 Kpa. The factors associated with the presence of F1 and/or F2 fibrosis were: diabetes (p=0.003, OR=16), age at the time of the study of more than 51.5 years (p=0.049) as well as an age of more than 36.5 years at diagnosis (p=0.020).

Conclusion

Apart from the known epidemiological factors associated with steatosis and hepatic fibrosis, our study showed that features related to corticosteroid therapy were associated with hepatic steatosis in patients with CD.

Introduction

Benign pancreatic disorders pose significant challenges in diagnosis, treatment, and management due to their complex nature and diverse etiology. As the prevalence of pancreatic diseases continues to rise, the demand for specialized care and expertise becomes imperative.
Thus the Section of Interdisciplinary Pancreatology (SIP) has been launched in 2023 at Ulm University Hospital to manage a broad spectrum of pancreatic disorders, encompassing cystic pancreatic lesions, autoimmune pancreatitis and IgG4-related disease (IgG4-RD), and all types of chronic pancreatitis.
Here, we will present insights from two years of experience within this unit, focusing on the disease spectrum, the impact of a multidisciplinary board structure, and the direct advantages of Patient-Reported Outcome Measures (PROMs) in enhancing patient care.

Aims & Methods

To basically show the structure of an interdisciplinary section of pancreatoloy and emphasise resulting advantages and chances in pancreas care. Moreover, descriptive analyses from PROMs, impact on decision making and paths will be shown.

Results

The structured implementation of the SIP created a level of interdisciplinarity that has not been achieved before. Thus collaborative efforts resulted in relevant changes of daily-patient care and patient paths. This is assessed and further shown by the integration of PROMs that are continuously recorded. By systematically collecting patient-reported data on symptoms, functional status, and treatment outcomes, the division gains valuable insights into the patient experience and treatment efficacy and allows patient centered therapy management. Specifically by the integration of a dedicated multidisciplinary board to review cases of benign pancreatic disorders, consensus-driven decision-making optimized diagnostic accuracy and therapeutic planning, fostering individualized approaches. One of these successful approaches that has been established are high numbers of hybrid procedures in robotic enucleation of pancreatic cysts.

Conclusion

In conclusion, our two-years experience in a division of interdisciplinary pancreatology underscores its efficacy in addressing the diverse array of pancreatic disorders. Through collaborative decision-making, regular case reviews, and the integration of PROMs, the SIP exemplifies a patient-centric approach to pancreatic care that prioritizes clinical excellence, interdisciplinary collaboration, and continuous quality improvement.

Introduction

This paired biopsy study aimed to investigate the predictive value of various non-invasive scores for identifying the temporal evolution of hepatic fibrosis in patients with non-alcoholic fatty liver disease (NAFLD).

Aims & Methods

A total of 69 patients with NAFLD who had undergone two paired liver biopsies (mean interval: 21.3 ± 9.7 months) were examined. Fibrosis progression and regression were defined as an increase or decrease of at least one stage in fibrosis between the initial and second biopsy. Fibrosis-4 index (FIB-4), NAFLD Fibrosis Score (NFS), Agile 3+ score, Agile 4 score, and FibroScan-AST (FAST) score were calculated at the time of the initial biopsy.

Results

Upon comparing the results of paired biopsies, 45% of the participants (n = 31) showed no change in fibrosis, 26% (n = 18) experienced fibrosis progression, and 29% (n = 20) had evidence of fibrosis regression. In multivariable logistic regression analysis, the only independent predictive factor for progressive fibrosis was the FAST score. The odds ratio for progressive fibrosis was found to increase by 19% (95% confidence interval: 8–38%, p < 0.05) with every unit increase in FAST score at the time of the initial biopsy. No independent predictors for fibrosis regression were identified.

Conclusion

Patients with higher baseline FAST scores were more likely to experience fibrosis progression independent of potential confounders. Consequently, FAST could serve not only as a diagnostic tool for screening fibrosis in NAFLD, but also as a prognostic indicator.

Introduction

Long-term maintenance treatment efficacy, safety and tolerability in eosinophilic esophagitis (EoE) is still partially understood. The aim of this study was to evaluate long-term outcomes of maintenance treatment for EoE with various drugs and dose regimens in real-world observational studies and randomized controlled trials (RCTs).

Aims & Methods

Systematic search was performed on Pubmed-MEDLINE, Embase and Cochrane Central Register of Controlled Trials from inception to October 2023. Studies reporting histologic success of maintenance therapy for EoE patients > 48 weeks, following 8-12 weeks of induction therapy with the same drug were included. Primary outcome was pooled histologic success (defined as < 15 eosinophils/HPF) at the end of follow-up for both study designs. Risk Difference (RD) or Odds Ratio (ORs) for histological success of maintenance therapy versus placebo (PBO) (for RCTs) and versus induction (for both study designs), pooled drug-related adverse events (AEs), endoscopic and clinical success rates were assessed as secondary outcomes. Random effects model metanalyses were performed. A-priori sub-group analyses were performed to address substantial inter-study heterogeneity (measured with I² statistic).

Results

From 3,916 full articles, 23 articles matched inclusion criteria (17 observational studies and 6 RCTs), 7 with pediatric patients only. Overall, 1,923 patients (M 70.1%; mean age 29.8±12.6 years). Mean follow-up time was 78.4 weeks. Budesonide (either oro-dispersible or viscous suspension) was administered in 7 studies (including 2 RCTs), PPI in 6 studies (all observational, 4 pediatric), Fluticasone in 5 studies (including 1 RCT with 4 cohorts), Dupilumab in 2 RCTs and Cendakimab in 1 RTC. Pooled rate of long-term histologic success for RCTs was 83% (95% CI, 77%-89%; I² 73.1%), while for observational studies attested at 53% (95% CI, 42%-65%; I² 93.5%) at a median follow-up of 97.8 weeks. Maintenance therapy in RCTs showed a RD of -0.71 (95% CI; -0.92-0.50; p<0.01; I² 88.9%) versus PBO, while a RD of -0.06 (95% CI; -0.11-0.01; p<0.016; I² 23.1%) compared with induction. Observational studies showed a non-significant (p=0.38) Odds Ratio (OR) of 1.37 (95% CI, 0.66-2.85; I² 81.3%) of losing histologic success during therapy de-escalation. Pooled clinical success among RCTs attested at 61% (95% CI, 51%-75%; I² 71.3%), comparable with observational studies (60% [95% CI, 42%-77%; I² 97.3%]). Biological therapy (either Dupilumab or Cendakimab at various regimens) ranked first for pooled histologic success rate among RCTs with 79% (95% CI; 71%-87%; I² 54.9%). In observational studies, PPI with histologic success of 64% (95% CI, 50%-78%; I² 88.7%) and clinical success of 79% (95% CI; 66%-93%; I² 85.2%) ranked first. Pooled rate of AEs among RCTs attested at 34% (95% CI; 22%-45%; I² 93.2%), with a pooled candidiasis infection rate of 6% (95% CI; 2%-10%; I² 61.9%), comparable with pooled AEs among observational studies (5% [95% CI, 2%-7%; I² 66.7%]). Pooled therapy discontinuation rate was 0.14 (95% CI, 0.073-0.210, I² 94.49%) in real-world data.

Conclusion

This is the first meta-analysis on efficacy and safety of long-term maintenance treatment (median 78 weeks) for EoE. All treatments showed good efficacy in maintaining long-term histological remission without clear disadvantage in de-escalating therapy during maintenance in real-word data. Biological therapies resulted the most effective in RCTs, while PPIs in observational studies. Low adverse events rates and low therapy discontinuation rates confirm long-term treatment is well tolerated.

Introduction

In cirrhosis, several prognostic scores have been developed to predict overall and complication-free survival. The MELD (Model for End-Stage Liver Disease), MELD-Na and MELD3.0 scores have been proposed as a criteria for allocating organs.

Aims & Methods

The aim of our study was to assess the performance of these 3 scores for the prediction of overall and complication-free survival in decompensated Tunisian cirrhotic patients.
Methods: We conducted an observational, retrospective study involving all patients with decompensated cirrhosis managed in Gastroenterology department of Taher Maamouri hospital during the period from January 2010 to December 2021. Mortality was assessed using the Kaplan Meier model. The performance of the scores was assessed using the AUROC (Area under the Receiver Operating Characteristic curve).

Results

One hundred and fifty-two patients were included with an average age of 61 years. Viral liver cirrhosis was the most common (65.13%). The mean value of the MELD-Na and MELD3.0 scores was 17.74 and 19.4, respectively. The mean follow-up time was 17.1 months. The rate of complications and short-term mortality was 33.6% and 18.4% respectively.
The AUROC of the MELD3.0 score in predicting of the occurrence of further decompensation was the highest (0.775) compared to those of the MELD and MELD-Na score (0.743 and 0.756 respectively). The cut-off value of the MELD3.0 score in predicting further decompensation was 20 (sensitivity 60.7%, specificity 73.3%).
In the prediction of 3-month mortality, the AUROCs of the MELD, MELD-Na and MELD3.0 scores were 0.786; 0.841 and 0.850 respectively. The cut-off value of the MELD3.0 score was 24 (sensitivity 68%, specificity 88%). A statistically significant correlation was noted between the MELD3.0 score ≥24 and 3-month mortality (p=0.04).

Conclusion

The MELD3.0 score had the best predictive value for the occurrence of further decompensation and short-term mortality in decompensated cirrhotic patients. Those with a MELD 3.0 score ≥24 should be prioritized on waiting lists.

Introduction

Piecemeal endoscopic mucosal resection (EMR) vs endoscopic submucosal dissection (ESD) has been a long standing debate in the endoscopic community worldwide with multiple studies done to evaluate the preferred method to manage large colorectal neoplasms. Piecemeal EMR with thermal ablation of the margin has been strongly advocated and reported by certain groups to be a simple, inexpensive and effective technique and this has been preferred widely due to its perceived ease of performance and shorter learning curve.¹ However, close, repeated surveillance colonoscopy is recommended even when the lesion is thought to have been completely resected² as residual tumors can cause interval cancers.³ Some groups, mainly from east Asian countries, have recommended en bloc resection by ESD due to significantly lower risk of local recurrence and precise pathological diagnosis.⁴ But its usage is limited due to concerns about risk of serious adverse events. With improvement in training and devices, colorectal ESD is now being performed by various centers globally. This study aims to report the outcomes of an international, multicenter study on colorectal ESD.

Aims & Methods

Patients who underwent colorectal ESD for lesions greater than 20mm between January 2022 to April 2024 from centers in USA, Japan, and India respectively were included in this study. Recurrent lesions after endoscopic therapy, neoplasms identified in patients with ulcerative colitis, and non-epithelial lesions were included. Primary outcomes were en bloc and R0 resection rate, delayed adverse events (bleeding/perforation), and local recurrence rate. Secondary outcomes were procedure time, lesion size, and pathology. Univariate and multivariate analysis were done to identify the risk factors for primary outcomes.

Results

309 patients (median size, 40(27.5-60)mm; location rectum 52.4%, left colon 26.2%, right colon 21.4%) were involved in this study. The en bloc resection rate was 96.1% and R0 resection rate was 90.3%. 3 patients experienced delayed bleeding which was managed endoscopically. 2 patients underwent surgery for delayed perforation. 6 patients had a local recurrence. 67(23%) patients had intramucosal carcinoma on pathology. Univariate analysis showed lesser procedure time (median(IQR) 145(80-236.25) vs 270(180-300) minutes, P= 0.005) and smaller lesion size (median(IQR) 40(26-56.25) vs 60(40-90) mm, P= 0.004) were significant factors for successful en bloc resection. However, lesser procedure time (median(IQR) 74(29.5-97.5) vs 150(82.5-240) minutes, P= 0.034) led to an increased delayed adverse event rate. Multivariate analysis using Cox regression showed en bloc resection (odds ratio 0.038; 95% confidence interval 0.003-0.421; P= 0.008) was an independent factor preventing local recurrence.

Conclusion

This international, multicenter study with data from three countries shows favorable outcomes for colorectal ESD for large lesions. The high en bloc and R0 resection rate, and low adverse event rate show increased global adaptation to this procedure. Reduced local recurrence is an added benefit. Data from a more centers globally will be valuable to establish ESD as the standard for large colorectal neoplasms.
