Faecalibacterium prausnitzii EXL01 Strain for the prevention of multiple-recurrent Clostridioides difficile Infection

Sep 17, 2026

The authors aimed to evaluate the efficacy of the Faecalibacterium prausnitzii EXL01 strain in preventing recurrent Clostridioides difficile infection (rCDI) by restoring microbiome functions. In a murine model and a phase I clinical trial with adults who had multiple CDI episodes, EXL01 demonstrated safety and a high rate of recurrence-free patients, suggesting its potential as a precision microbiome therapeutic. The study highlights the importance of targeting microbiome function rather than solely focusing on taxonomic diversity in treating rCDI.

Short-Term Success, Long-Term Failure: Strain Turnover and Virulence Re-Emergence May Drive Relapse in Pouchitis

Sep 9, 2026

The authors investigate how antibiotic treatment influences microbial shifts in patients with pouchitis, particularly focusing on the mechanisms behind remission and subsequent relapse. They found that while antibiotics temporarily reduce inflammation and harmful bacterial genes, resistant strains quickly rebound after treatment, suggesting that transient remission may allow low-virulence strains to dominate. This highlights the necessity for targeted strategies to achieve long-term microbial control in pouchitis management.

Impact of Family History on Colorectal Cancer Risk in Inflammatory Bowel Disease and in Matched General Population Comparators

Sep 3, 2026

The authors aimed to investigate how family history of colorectal cancer (CRC) influences CRC incidence in patients with inflammatory bowel disease (IBD) compared to a matched general population. Their findings indicate that while family history increases CRC incidence in both groups, the effect is more pronounced in individuals with multiple affected relatives, suggesting a need to reconsider surveillance strategies for CRC in IBD patients based on family history.

Individualized targeted exclusion diet based on confocal laser endomicroscopy does not improve irritable bowel syndrome symptoms: a randomized controlled crossover trial

Sep 1, 2026

The authors aimed to determine whether a targeted exclusion diet, based on food-induced mucosal alterations visualized through confocal laser endomicroscopy (CLE), could improve symptoms in patients with irritable bowel syndrome (IBS). In a randomized controlled crossover trial, they found no significant difference in clinical response rates between the real diet and a sham diet, suggesting that the mucosal changes observed may not be specific indicators of dietary triggers in IBS. The study challenges the clinical utility of CLE for identifying foods that exacerbate IBS symptoms.

Management of Obesity: Review of Adjunctive Therapies and Clinical Management Pearls

Aug 31, 2026

The authors aim to review the current landscape of obesity management, including new and emerging therapies, while addressing the challenges that hinder effective treatment in the US. They highlight the role of gastroenterologists in obesity care, given their expertise in gut-related therapies, and provide insights into clinical management strategies for various obesity treatments. Despite advancements, the persistent rate of obesity suggests that factors such as cost, insurance coverage, and provider availability continue to impede effective care.

The CA19-9 glycan is a viable target for CAR T cell therapy in pancreatic and other solid tumors

Aug 27, 2026

The authors investigate the potential of targeting the CA19-9 glycan for CAR T cell therapy in pancreatic ductal adenocarcinoma (PDAC) and other solid tumors, addressing the challenge of finding tumor-specific cell-surface targets. They designed and tested 14 CAR constructs, ultimately identifying one, AbLIFT15.28z, that demonstrated effective T cell expansion and specific anti-tumor activity against CA19-9-expressing cancers in various pre-clinical models. The study supports the clinical development of CA19-9 CAR T cells for treating gastrointestinal cancers.

Fibroblast-derived Spondin-2 promotes dysplastic transition in metaplastic gastric epithelial cells

Aug 25, 2026

The authors investigate the role of fibroblast-derived factors in the transition from metaplasia to dysplasia in gastric epithelial cells, identifying Spondin-2 (SPON2) as a key mediator of this process. Through various techniques, including single-cell RNA sequencing and spatial transcriptomics, they demonstrate that SPON2 promotes dysplastic changes in metaplastic gastroids, highlighting its potential as a significant factor in early gastric carcinogenesis. Ultimately, the study positions SPON2 as the first identified fibroblast-derived factor that drives pre-neoplastic progression in gastric epithelium.

Global Prevalence of Celiac Disease and Clinical Characteristics in the General Population: A Systematic Review and Meta-analysis

Aug 18, 2026

The authors aimed to update the global prevalence estimates of celiac disease (CeD) and characterize its clinical features, as well as assess the impact of diagnostic methods on detection rates. Their systematic review and meta-analysis of 87 studies revealed a global seroprevalence of 1.5% and a biopsy-confirmed prevalence of 0.8%, with significant variations based on demographics and diagnostic approaches. Notably, around 41% of biopsy-confirmed patients were asymptomatic, underscoring the need for improved detection strategies worldwide.

WISP1 Drives Intestinal Fibrosis in Crohn's Disease via Metabolic and Rho/ROCK/MRTF-mediated cytoskeletal Remodeling

Aug 18, 2026

This study investigates the role of WISP1 in driving intestinal fibrosis in Crohn's disease by examining its effects on fibroblast activation, metabolic reprogramming, and extracellular matrix remodeling. The authors found that WISP1 is highly expressed in fibrotic tissues and promotes a shift in fibroblast metabolism that contributes to fibrosis through the RHO/ROCK/MRTF pathway. Neutralizing WISP1 in a murine model reduced fibrosis and inflammation, suggesting it could be a viable target for antifibrotic therapies in Crohn's disease.

WNT-driven immune evasion promotes malignant transformation of BRAF-mutant colorectal cancer

Aug 18, 2026

The authors investigate the role of WNT pathway activation in the progression of BRAF-mutant colorectal cancer (CRC) and its impact on tumor-immune interactions. They find that WNT activation is essential for tumor initiation and promotes immune evasion by remodeling the tumor microenvironment, ultimately driving malignant transformation in this aggressive CRC subtype. These results suggest that targeting WNT signaling could be a promising therapeutic strategy for BRAF-mutant MSS CRC.
