OBJECTIVES Despite increased prescription of a gluten-free diet for gastrointestinal symptoms in individuals who do not have celiac disease, there is minimal evidence that suggests that gluten is a trigger. The aims of this study were to determine whether gluten ingestion can induce symptoms in non-celiac individuals and to examine the mechanism. METHODS(More)
BACKGROUND AND AIM Reduction of short-chain poorly absorbed carbohydrates (FODMAPs) in the diet reduces symptoms of irritable bowel syndrome (IBS). In the present study, we aimed to compare the patterns of breath hydrogen and methane and symptoms produced in response to diets that differed only in FODMAP content. METHODS Fifteen healthy subjects and 15(More)
BACKGROUND Circulating concentrations of 6-thioguanine nucleotide (6-TGN) and 6-methyl mercaptopurine (6-MMP) are associated with thiopurine efficacy and may predict toxicity. This study aimed to examine retrospectively the utility of measuring metabolite concentrations in patients with inflammatory bowel disease (IBD) who had continuing symptoms despite(More)
BACKGROUND Emerging evidence indicates that the consumption of fermentable oligosaccharides, disaccharides, monosaccharides and polyols (FODMAPs) may result in symptoms in some patients with irritable bowel syndrome (IBS). The present study aimed to determine whether a low FODMAP diet is effective for symptom control in patients with IBS and to compare its(More)
BACKGROUND & AIMS There is debate over whether patients with Crohn's disease who start anti-tumor necrosis factor (TNF) therapy after failed immunomodulator therapy should continue to receive concomitant immunomodulators. We conducted a meta-analysis of subgroups from randomized controlled trials (RCTs) of anti-TNF agents to compare the efficacy and safety(More)
BACKGROUND Hidradenitis suppurativa is a rare chronic inflammatory disorder of apocrine gland-bearing skin, which commonly affects the anogenital region. There has been very little literature to date on the MRI appearances of anogenital hidradenitis suppurativa. OBJECTIVE The aim of this study was to assess the MRI features of anogenital hidradenitis(More)
The results of an audit of the admission of epilepsy sufferers in a UK District General Hospital are presented. The results strongly suggest that most admissions were due to potentially mutable problems including poor compliance with medication rather than to difficult epilepsy per se. It is suggested that consistent support of these patients, for example(More)
Preliminary studies indicate that dietary restriction of fermentable short-chain carbohydrates improves symptoms in irritable bowel syndrome (IBS). Prebiotic fructo-oligosaccharides and galacto-oligosaccharides stimulate colonic bifidobacteria. However, the effect of restricting fermentable short-chain carbohydrates on the gastrointestinal (GI) microbiota(More)
Up to 1/5 of patients with wildtype thiopurine-S-methyltransferase (TPMT) activity prescribed azathioprine (AZA) or mercaptopurine (MP) demonstrate a skewed drug metabolism in which MP is preferentially methylated to yield methylmercaptopurine (MeMP). This is known as thiopurine hypermethylation and is associated with drug toxicity and treatment(More)
BACKGROUND Functional gut symptoms are induced by inclusion and reduced by dietary restriction of poorly absorbed short-chain carbohydrates (FODMAPs), but the mechanisms of action remain untested. AIMS To determine the effect of dietary FODMAPs on the content of water and fermentable substrates of ileal effluent. METHODS Twelve ileostomates without(More)
