The prevalence of small intestinal bacterial overgrowth in non-surgical patients with chronic pancreatitis and pancreatic exocrine insufficiency (PEI)

BACKGROUND: Small intestinal bacterial overgrowth (SIBO) is a condition characterised by symptoms similar to pancreatic exocrineinsufficiency (PEI) in chronic pancreatitis patients. SIBO is thought to complicate chronic pancreatitis in up to 92% of cases; however, studies are heterogeneous and protocols non-standardised. SIBO may be determined by measuring lung air-expiration of either hydrogen or methane which are...Читать далее »

Morphological and functional alterations of small intestine in chronic pancreatitis

CONTEXT: The small intestine in chronic pancreatitis has not been investigated yet thoroughly. It would be important to understand fat metabolism in the course of this disease and could be explained if the small intestine has some pathological conditions and, due to this reason, pancreatic enzyme substitution does not work in all patients. OBJECTIVE: To investigate the pathophysiology of small intestine in chronic pancreatitis...Читать далее »

Vedolizumab Drug Level Correlation With Clinical Remission, Biomarker Normalization, and Mucosal Healing in Inflammatory Bowel Disease

BACKGROUND/AIMS: The clinical utility of vedolizumab (VDZ) trough levels (VTLs) in inflammatory bowel disease (IBD) is not well defined. The aims of this study are to determine the median VTLs and frequency of detected antibodies, the correlation of VTLs with C-reactive protein (CRP) and mucosal healing (MH), and the change in clinical management based on VTLs. METHODS: A cross-sectional study of IBD patients treated with VDZ with VTLs...Читать далее »

The Transient Receptor Potential Vanilloid 1 Is Associated with Active Inflammation in Ulcerative Colitis

The transient receptor potential vanilloid 1 (TRPV1) may play a role in the pathogenesis of ulcerative colitis (UC). The aim of the study was to determine the gene and protein expression of TRPV1 in UC patients and noninflamed controls. Gene expression was performed by RT-PCR, and protein expression was performed by immunohistochemistry. The gene expression of TRPV1 was significantly increased in the remission UC group compared...Читать далее »

Frequency of food hypersensitivity in patients with Functional Gastrointestinal Disorders

BACKGROUND AND STUDY AIMS: Food hypersensitivity (FH), irritable bowel syndrome (IBS) and functional dyspepsia (FD) have many overlapping symptoms, including abdominal discomfort, bloating, and altered bowel habits. We aimed to determine the frequency of FH in patients with IBS and functional FD. PATIENTS AND METHODS: Adult patients of either gender diagnosed with IBS and/or FD as per the Rome III criteria were recruited. Patients underwent serological...Читать далее »

A global vision of adverse reactions to foods: food allergy and food intolerance

Over the last years, there has been an increase in adverse food reactions, probably associated with life style changes in the past decades. An adverse food reaction is any clinically abnormal response that can be attributed to ingestion, contact or inhalation of a food, its derivatives or an additive contained in it. They can be classified as food allergy or intolerance. Food allergies are usually immune-mediated,...Читать далее »
