BACKGROUND & AIMS Despite treatment with corticosteroids, severe to moderately severe attacks of ulcerative colitis have a high colectomy rate. We intended to find a rescue therapy other than cyclosporin A, which imposes a high risk of side effects and cyclosporine-related mortality. METHODS This was a randomized double-blind trial of infliximab or(More)
BACKGROUND The long-term efficacy of infliximab as rescue therapy in steroid-refractory ulcerative colitis is not well described. AIM To examine the long-term efficacy of infliximab as a rescue therapy through a 3-year follow-up of a previous placebo-controlled trial of infliximab in acute steroid-refractory ulcerative colitis. METHOD In the original(More)
BACKGROUND Irritable bowel syndrome (IBS) is commonly thought to be associated with psychologic distress. However, in some studies only persons who had sought medical care for IBS (IBS patients) showed an increased frequency of psychiatric symptoms, and nonpatients did not differ significantly from normal subjects. Our aims were 1) to estimate the(More)
BACKGROUND Only one-fifth of chronic alcoholic patients develop chronic liver disease in spite of continuous alcohol abuse. Hepatitis C has been proposed to be one of several suggested factors contributing to the development of liver disease. METHODS In 201 consecutive chronic alcoholic patients admitted to the hospital for detoxification, antibodies to(More)
Evaluation of small bowel transit, which should preferably be performed using non-invasive techniques, is complex owing to the anatomical position of the small bowel. In order to avoid any influence of the gastric emptying rate on scintigraphic results, we have used (99m)Tc-HIDA, an intravenous tracer that is excreted in bile and thereby delivered directly(More)
Symptoms from the gastro-intestinal tract are common and often difficult to evaluate. Specialised examination techniques are available only at a limited number of clinics. A technique based on biliary scintigraphy when measuring the transit of contents through the small intestine has been developed. The investigation is simple to perform and convenient for(More)
A woman who was investigated because of suspected malabsorption was found to excrete large amounts of 3,6-epoxyoctanedioic, 3,6-epoxydecanedioic and 3,6-epoxydodecanedioic acids. The origin of these compounds could be traced to the factitious ingestion of castor oil. Healthy subjects and conventional as well as germ-free rats also excrete these substances(More)
BACKGROUND It has been suggested that psychopathology in irritable bowel syndrome (IBS) patients is a function of patient status rather than of the disease. Although there are many studies comparing IBS patients, IBS non-patients, and controls with each other, no previous study has recruited all three groups from a representative community sample and had(More)
BACKGROUND We recently reported increased intestinal permeability to polysucrose (PS) 15000 in patients with Crohn's disease and in patients treated with non-steroidal anti-inflammatory drugs (NSAIDs). We have now compared this new macromolecular marker (14,700 D) with the conventional markers, 51Cr-labelled ethylenediaminetetraacetic acid (EDTA) (342 D)(More)
Intestinal tight junction function is thought to be of importance in the pathogenesis of various diseases. The regulation of uptake of macromolecules via the tight junctions is largely unknown. Effects of luminal sodium caprate (10 mM), a dairy product constituent, and cytochalasin B (30 microM), were studied in rat ileum in vitro in Ussing chambers. Both(More)
