Ulcerative colitis (UC) is a chronic debilitating disease that affects about 150,000 people in the UK, where the colon and rectum become inflamed, causing diarrhoea and abdominal pain. It often leads to frequent and long in-patients stays and emergency colectomy (surgery to remove the colon), and is therefore a major burden on patients and NHS resources. Recent studies have reported that two drugs, infliximab and cyclosporin, are often effective at treating steroid-resistant ulcerative colitis in the short term, but there was a lack of studies comparing the two treatments. The aim of this study was to compare the clinical and cost effectiveness of infliximab and ciclosporin in acute severe steroid-resistant ulcerative colitis.
The CONSTRUCT trial aimed to test their relative clinical effectiveness, measured by quality of life and cost-effectiveness. The study, led by Prof John Williams from Swansea and funded by the NIHR Health Technology Assessment (HTA) Programme, recruited 270 patients from 52 hospitals across England, Scotland and Wales. The gastroenterology community worked hard to deliver this largest study ever done in acutely ill hospitalised UC patients. It found that Cyclosporin and infliximab were both equally effective in treating acute severe colitis.
In Barrett’s oesophagus, the cells that line the oesophagus become damaged by acid reflux, which can cause symptoms such as indigestion and heartburn. Over a long period of time, people with Barrett's oesophagus can develop ulcers or a narrowing of the oesophagus, and in some cases oesophageal cancer.
The ‘Cytosponge’ is a ‘pill on a string’ that is being tested to detect oesophageal cancer in people with Barrett’s oesophagus. The Cytosponge sits within a pill which, when swallowed, dissolves to reveal a sponge that scrapes off cells when withdrawn up the gullet. It allows doctors to collect cells from all along the gullet, whereas standard biopsies take individual point samples, to diagnose.
The device was initially tested at the NIHR Cambridge Clinical Research Facility. Further research, funded by Cancer Research UK, is supported by the NIHR Clinical Research Network. The latest trial, which aims to recruit nearly 9000 patients, is the last step required before the Cytosponge could be adopted into mainstream practice.
Crohn’s disease is a serious disease in which there is swelling and ulceration of the gut wall. Most patients are treated with medicines. But after ten years, 2 out 3 people with Crohn’s disease will need an operation. Crohn’s disease can often come back after an operation, and almost half those who had an operation will need another one.
Several medicines have been tested to see if they help stop Crohn’s disease coming back after an operation. The 5ASA medicines are not very good at stopping Crohn’s coming back. Antibiotics have some effect but cannot be taken for very long because of side effects. Azathioprine and 6-Mercaptopurine (together known as thiopurines) are medicines that alter the way the immune system works. Over the last 10 years, they have become widely used for Crohn’s disease when it is not easily treated with other medicines but is not serious enough to need an operation. They have also been tested to see if they can stop Crohn’s disease coming back after an operation, but those studies have been flawed and the results have been unhelpful for doctors.
Led by Prof Jack Satsangi and funded by the Medical Research Council, the TOPPIC study recruited 240 patients from 29 UK hospitals between 2008 and 2012. The study randomly allocated patients to receive 6-Mercaptopurine or placebo. It found that smokers had a high rate of recurrence of Crohn’s disease and 6-Mercaptopurine was effective in preventing recurrence mainly in smokers.
Bowel cancer is common in the UK. Most bowel cancers happen when a type of polyp (a growth in the bowel) called an adenoma becomes cancerous. Doctors use a camera test, known as a colonoscopy, to look inside the bowel, find these polyps and remove them. Removing pre-cancerous polyps is known to reduce the chances of a person developing bowel cancer in the future. How good colonoscopists are at finding these polyps varies, and there is a lot of research into how to improve “adenoma detection rates”.
A new device, called the Endocuff Vision (a small plastic device attached to the end of the colonoscope which holds the folds of the bowel back to give a clear view of the inside of the bowel) has been shown to improve the rate of polyp detection at colonoscopy, and to make polyp removal easier. Previous small studies have shown that there is a significant improvement in detection of adenomas when an Endocuff Vision is used (with the rate of detection of adenomas rising from 49% to 66%).
The ADENOMA study (led by Prof Colin Rees) randomly allocated patients coming for colonoscopy to have their procedure performed as usual (i.e. without the Endocuff Vision attached) or as an Endocuff-assisted colonoscopy. The study aimed to recruit 1772 patients across England in 7 centres (1 in London and the remainder in North East England) and did this successfully ahead of time.

The NIHR Clinical Research Network (CRN) provides researchers with the practical support they need to make clinical studies happen in the NHS. We provide world-class health service infrastructure - research support staff such as clinical research nurses, and research support services such as pharmacy, pathology and radiology - to support organisations seeking to conduct clinical research in the NHS in England. Some of this research is funded by the NIHR, but most of it is funded by NHS non-commercial partners and industry.
We support the set up and delivery of clinical research in the NHS through our Study Support Service and our Research Design Service helps researchers develop proposals to secure funding from our research programmes.
The Gastroenterology Specialty is one of 30 specialties which bring together communities of clinical practice to provide national networks of research expertise and clinical leadership. It is made up of research-interested clinicians and practitioners who work at both national and local levels to ensure the studies that are included in our national portfolio of research are delivered successfully in the NHS- to time and target.
The Gastroenterology Specialty supports a national portfolio of high quality research studies relating to the pathogenesis, diagnosis, treatment and prevention of gastrointestinal disorders. We support researchers to deliver high quality studies to time and target in the NHS. We do this by engaging with the existing research community and developing local research infrastructure.
The Clinical Research Network is made up of 15 localities covering England. Each one has a nominated local lead for gastroenterology research who promotes and supports gastroenterology research within the NHS Trusts in their area. At a national level the local leads come together to manage the national gastroenterology research portfolio overall. This involves regularly reviewing the progress of studies, identifying barriers to recruitment, and coming up with solutions and strategies to help overcome those barriers. The national Specialty Groups also engage with funders of research and other stakeholders to help ensure that there is a continuous pipeline of high quality research studies and the capacity to deliver these successfully in the NHS.
The Gastroenterology Specialty portfolio covers research pertaining to the whole gastrointestinal tract and includes:
