BACKGROUND Irritable bowel syndrome (IBS) prevalence estimates are essential for measuring the importance of the problem and the burden of the illness. However, IBS diagnosis is based on clinical criteria which have changed over time. The aim of this study was to assess how the use of different diagnostic criteria influences estimated IBS prevalence and, in(More)
BACKGROUND Functional digestive disorders constitute a sizable proportion of gastroenterology and primary healthcare consultations, and have a negative impact on health-related quality of life. Dyspepsia and heartburn are often associated with irritable bowel syndrome (IBS); however, the incidence of these symptoms and their effect on IBS patients have not(More)
Interleukin-1 beta (IL-1 beta) has recently been shown to reduce the severity of experimental gastroduodenal damage and to inhibit acid secretion in the pylorus-ligated rat. In the present study, the effects of IL-1 beta on pentagastrin-stimulated acid secretion were compared with those of two other cytokines, namely IL-1 alpha and tumor necrosis factor(More)
OBJECTIVE Therapeutic trials in functional dyspepsia consistently show a substantial placebo response, but there is no clear explanation for such an effect. Our aim was to evaluate symptomatic, gastrointestinal motor, and gastric sensorial responses to placebo treatment in patients with chronic and severe functional dyspepsia who were part of a therapeutic(More)
BACKGROUND There is very little information available on the incidence of complications and on the best prevention therapy in high-risk patients taking non-steroidal anti-inflammatory drugs (NSAIDs) and/or aspirin. Randomized-controlled trials in such patients are rare for ethical reasons. We studied the incidence of gastrointestinal complications in(More)
BACKGROUND Disturbed bowel habit, diarrhoea or constipation is a key manifestation of irritable bowel syndrome (IBS). In some patients, diarrhoea and constipation alternate, giving rise to the so-called alternating subtype. AIMS To assess IBS subtype breakdown (constipation (C-IBS), diarrhoea (D-IBS) or alternating (A-IBS)) according to the Rome II(More)
OBJECTIVES To evaluate the burden of illness in irritable bowel syndrome (IBS), in terms of resource utilisation (direct and indirect) and health-related quality of life (HR-QOL), in individuals with IBS who meet Rome I and Rome II criteria. METHODS A cross-sectional study, carried out by personal interview, on a representative sample (n = 2000) of the(More)
The purpose of the study was to evaluate the efficacy of preoperative intravenous (IV) ferric carboxymaltose (FCM) administration vs. no-IV iron in colon cancer (CC) anemic patients undergoing elective surgery with curative intention. This was a multicenter, observational study including two cohorts of consecutive CC anemic patients: the no-IV iron(More)
It was hypothesized that symptoms in functional dyspepsia are originated by an altered mechanism at the brain-gut axis (one or several) in the process of gastric accommodation to a meal. To test the key mechanisms potentially involved in symptomatic gastric accommodation, the sensorial responses (on a 0-10 perception score) and the gastric tone responses(More)
Interleukin 1 (IL-1) has been shown to reduce the severity of experimental gastroduodenal ulceration, but the mechanism of action is unclear. The present study examined the possibility that the mechanism underlying the protective effects of IL-1 in experimental nonsteroidal anti-inflammatory drug (NSAID)-induced gastropathy is related to effects on gastric(More)
