Background: While the importance of diet in the pathogenesis of inflammatory bowel disease (IBD) is generally recognized, influence of food on the course of IBD is little understood.
Aim: The purpose of this study was to assess the association between food intake and course of disease in patients with IBD.
Methods: We performed a cross-sectional study on 103 adult patients (50 with active disease and 53 in remission, divided by their calprotectin level), who completed a food frequency questionnaire on their intake of several foods over 1 year.
Background: An imbalance in gut microbiota seems to contribute to the development of chronic inflammatory disorders of the gastrointestinal tract, such as ulcerative colitis (UC). Although it has been suggested that probiotic supplementation is an effective approach to colitis, its effects on intestinal flora and on mucosal cytokine balance have never been explored.
Aim: To evaluate the effect of Lactobacillus casei (L.
Background: Capsule enteroscopy is considered the gold standard for evaluating patients with obscure gastrointestinal bleeding. The costs of capsule enteroscopy examination, however, make it uncertain whether the clinically relevant diagnostic gain is also associated with cost savings.
Aim: To evaluate the incremental cost-effectiveness ratio of capsule enteroscopy in patients with obscure gastrointestinal bleeding.
Background And Aims: Calprotectin and lactoferrin are specific neutrophil-derived proteins, which can be measured in the feces because they are released by cells in inflammatory conditions. We evaluated the efficacy of calprotectin and lactoferrin in detecting organic disease as assessed by colonoscopy.
Methods: The study comprised 144 patients undergoing colonoscopy for lower gastrointestinal symptoms (abdominal pain, altered bowel habits, and bloody stools) (67), or inflammatory bowel disease activity, or surveillance for dysplasia (77).
Objectives: To assess the diagnostic efficiency of capsule endoscopy in a large group of patients with different indications, to weigh the reliability of the procedure for excluding small bowel lesions, and to identify factors associated with the likelihood of obtaining a definitive diagnosis.
Methods: Three hundred four consecutive patients (141 female, mean age 55 years, range 12-91 years) underwent capsule endoscopy in two different Gastroenterology Units, for a total of 314 procedures, and were followed-up for a median period of 15 months. Referrals were obscure occult/overt gastrointestinal bleeding (203 patients), suspected small bowel disease (74), gastrointestinal polyposis (18), suspected/previous intestinal or endocrine malignancies (13), previously diagnosed intestinal lymphangectasia (3), and vascular abnormalities (3).
Objective: Capsule endoscopy is becoming known as a valid tool for identifying sources of obscure gastrointestinal (GI) bleeding. Fewer data are available about its clinical value for other indications.
Material And Methods: Sixty patients (31 F, mean age 47 years, range 14-80 years) with no signs of overt GI bleeding were investigated by Given M2A video capsule for suspected small-bowel disease.
