Distinct abnormalities of small bowel and regional colonic volumes in subtypes of irritable bowel syndrome revealed by MRI (2016)
Journal Article
Lam, C., Chaddock, G., Marciani, L., Costigan, C., Cox, E., Hoad, C., Pritchard, S. E., Gowland, P. A., & Spiller, R. C. (in press). Distinct abnormalities of small bowel and regional colonic volumes in subtypes of irritable bowel syndrome revealed by MRI. American Journal of Gastroenterology, https://doi.org/10.1038/ajg.2016.538

OBJECTIVES: Non-invasive biomarkers which identify different mechanisms of disease in subgroups of irritable bowel syndrome (IBS) could be valuable. Our aim was to seek useful magnetic resonance imaging (MRI) parameters that could distinguish each IB...

Colon hypersensitivity to distension, rather than excessive gas production, produces carbohydrate-related symptoms in individuals with irritable bowel syndrome (2016)
Journal Article

Colon hypersensitivity to distension, rather than excessive gas production, produces carbohydrate-related symptoms in individuals with irritable bowel syndrome. Gastroenterology, 152(1), 124-133.e2. https://doi.org/10.1053/j.gastro.2016.09.062

Background & Aims: Poorly digested, fermentable carbohydrates may induce symptoms of irritable bowel syndrome (IBS), via unclear mechanisms. We performed a randomized trial with magnetic resonance imaging (MRI) analysis to investigate correlations be...

Patients with chronic kidney disease have abnormal upper gastro-intestinal tract digestive function: a study of uremic enteropathy: small bowel dysfunction in CKD (2016)
Journal Article
Grant, C. J., Harrison, L. E., Hoad, C. L., Marciani, L., Gowland, P. A., & McIntyre, C. W. (2017). Patients with chronic kidney disease have abnormal upper gastro-intestinal tract digestive function: a study of uremic enteropathy: small bowel dysfunction in CKD. Journal of Gastroenterology and Hepatology, 32(2), 372-377. https://doi.org/10.1111/jgh.13458

Background and Aim: Chronic kidney disease (CKD) affects gastrointestinal (GI) function and results in numerous adaptive and maladaptive responses. Disruption of the colonic microbiome and its attendant consequences—the loss of gut barrier integrity...

Corticotrophin releasing factor increases ascending colon volume after a fructose test meal in healthy humans: a randomised control trial (2016)
Journal Article
Murray, K., Lam, C., Rehman, S., Marciani, L., Costigan, C., Hoad, C., …Spiller, R. C. (2016). Corticotrophin releasing factor increases ascending colon volume after a fructose test meal in healthy humans: a randomised control trial. American Journal of Clinical Nutrition, 103(5), https://doi.org/10.3945/ajcn.115.125047

Background: Poorly absorbed, fermentable carbohydrates can provoke irritable bowel syndrome (IBS) symptoms by escaping absorption in the small bowel and being rapidly fermented in the colon in some susceptible subjects. IBS patients are often anxious... Read More about Corticotrophin releasing factor increases ascending colon volume after a fructose test meal in healthy humans: a randomised control trial.

Colonic response to laxative ingestion as assessed by MRI differs in constipated irritable bowel syndrome compared to functional constipation (2016)
Journal Article

Colonic response to laxative ingestion as assessed by MRI differs in constipated irritable bowel syndrome compared to functional constipation. Neurogastroenterology and Motility, 28(6), https://doi.org/10.1111/nmo.12784

Background

Functional constipation (FC) and irritable bowel syndrome with constipation (IBS-C) share many symptoms but underlying mechanisms may be different. We have developed a magnetic resonance imaging (MRI) technique to measure intestinal vol...

Neurogastroenterology and Motility, 28(4), 554-568. https://doi.org/10.1111/nmo.12752

Background: Current investigations of stomach function are based on small test meals that do not reliably induce symptoms and analysis techniques that rarely detect clinically relevant dysfunction. This study introduces the large ‘Nottingham Test Mea...
