Designing clinical trials in paediatric inflammatory bowel diseases: a PIBDnet commentary.

Gut 2019 Apr 12. Epub 2019 Apr 12.

Université Paris-Descartes, Paris-Sorbonne Cité, Paris, France.

Introduction: The optimal trial design for assessing novel therapies in paediatric IBD (PIBD) is a subject of intense ongoing global discussions and debate among the different stakeholders. However, there is a consensus that the current situation in which most medications used in children with IBD are prescribed as off-label without sufficient paediatric data is unacceptable. Shortening the time lag between adult and paediatric approval of drugs is of the upmost importance. Read More

Effect of scheduled endoscopic dilatation of dominant strictures on outcome in patients with primary sclerosing cholangitis.

Gut 2019 Mar 25. Epub 2019 Mar 25.

Department of Internal Medicine IV, University Hospital of Heidelberg, Heidelberg, Germany.

Objective: Scheduled endoscopic dilatation of dominant strictures (DS) in primary sclerosing cholangitis (PSC) might improve outcome relative to endoscopic treatment on demand, but evidence is limited. Since randomisation is difficult in clinical practice, we present a large retrospective study comparing scheduled versus on-demand endoscopic retrograde cholangiopancreatography (ERCP) based on patient preferences.

Design: Between 1987 and 2017, all new patients with PSC had been offered scheduled ERCP with dilatation of a DS if diagnosed; the latter was repeated at defined intervals until morphological resolution, independent of clinical symptoms (treatment group). Read More

Crypt fusion as a homeostatic mechanism in the human colon.

Gut 2019 Mar 14. Epub 2019 Mar 14.

Centre for Tumour Biology, Barts Cancer Institute, Queen Mary University of London, London, UK.

Objective: The crypt population in the human intestine is dynamic: crypts can divide to produce two new daughter crypts through a process termed crypt fission, but whether this is balanced by a second process to remove crypts, as recently shown in mouse models, is uncertain. We examined whether crypt fusion (the process of two neighbouring crypts fusing into a single daughter crypt) occurs in the human colon.

Design: We used somatic alterations in the gene cytochrome c oxidase (CCO) as lineage tracing markers to assess the clonality of bifurcating colon crypts (n=309 bifurcating crypts from 13 patients). Read More

GABRP regulates chemokine signalling, macrophage recruitment and tumour progression in pancreatic cancer through tuning KCNN4-mediated Ca signalling in a GABA-independent manner.

Gut 2019 Mar 2. Epub 2019 Mar 2.

State Key Laboratory of Oncogenes and Related Genes, Shanghai Cancer Institute, Ren Ji Hospital, School of Medicine, Shanghai Jiao Tong University, Shanghai, China.

Background And Aims: Pancreatic ductal adenocarcinoma (PDAC) is a leading cause of cancer-related death worldwide. Neurotransmitter-initiated signalling pathway is profoundly implicated in tumour initiation and progression. Here, we investigated whether dysregulated neurotransmitter receptors play a role during pancreatic tumourigenesis. Read More

Microbial bile salt hydrolases mediate the efficacy of faecal microbiota transplant in the treatment of recurrent infection.

Gut 2019 Feb 11. Epub 2019 Feb 11.

Division of Integrative Systems Medicine and Digestive Disease, Department of Surgery and Cancer, Faculty of Medicine, Imperial College London, London, UK.

Objective: Faecal microbiota transplant (FMT) effectively treats recurrent infection (rCDI), but its mechanisms of action remain poorly defined. Certain bile acids affect germination or vegetative growth. We hypothesised that loss of gut microbiota-derived bile salt hydrolases (BSHs) predisposes to CDI by perturbing gut bile metabolism, and that BSH restitution is a key mediator of FMT's efficacy in treating the condition.

Real-time automatic detection system increases colonoscopic polyp and adenoma detection rates: a prospective randomised controlled study.

Gut 2019 Feb 27. Epub 2019 Feb 27.

Department of Gastroenterology, Sichuan Academy of Medical Sciences & Sichuan Provincial People's Hospital, Chengdu, China.

Objective: The effect of colonoscopy on colorectal cancer mortality is limited by several factors, among them a certain miss rate, leading to limited adenoma detection rates (ADRs). We investigated the effect of an automatic polyp detection system based on deep learning on polyp detection rate and ADR.

Design: In an open, non-blinded trial, consecutive patients were prospectively randomised to undergo diagnostic colonoscopy with or without assistance of a real-time automatic polyp detection system providing a simultaneous visual notice and sound alarm on polyp detection. Read More
