Novel ciliate lipases for enzyme replacement during exocrine pancreatic insufficiency


AIM AND OBJECTIVES: Exocrine pancreatic insufficiency caused by inflammation or pancreatic tumors results in nutrient malfunction by a lack of digestive enzymes and neutralization compounds. Despite satisfactory clinical results with current enzyme therapies, a normalization of fat absorption in patients is rare. An individualized therapy is required that includes high dosage of enzymatic units, usage of enteric coating, and...Читать далее »

Ataluren-driven restoration of Shwachman-Bodian-Diamond syndrome protein function in Shwachman-Diamond syndrome bone marrow cells


Shwachman-Diamond syndrome (SDS) is a rare inherited recessive disease mainly caused by mutations in the Shwachman-Bodian-Diamond syndrome (SBDS) gene, which encodes for the homonymous protein SBDS, whose function still remains to be fully established. SDS affects several organs causing bone marrow failure, exocrine pancreatic insufficiency, skeletal malformations, and cognitive disorders. About 15% of SDS patients develop myelodysplastic syndrome (MDS) and...Читать далее »

Diagnosis and treatment of pancreatic exocrine insufficiency


PURPOSE OF REVIEW: Pancreatic exocrine insufficiency (PEI), defined as a secretion of pancreatic enzymes and bicarbonate insufficient to maintain a normal digestion, is a frequent but frequently underdiagnosed and undertreated condition. PEI may be secondary to different pancreatic diseases and extrapancreatic conditions. Recent data support the high clinical relevance of PEI and its treatment. RECENT FINDINGS: Together with symptoms...Читать далее »

The role of central pancreatectomy in pancreatic surgery: a systematic review and meta-analysis


BACKGROUND: The aim of this systematic review and meta-analysis was to compare the clinical outcomes of central pancreatectomy (CP) with distal pancreatectomy (DP) and pancreaticoduodenectomy (PD). METHODS: A systematic literature research in PubMed/Medline, Embase and Cochrane Library was performed to identify articles reporting CP from January 1983 to November 2017. RESULTS: Fifty studies with 1305 patients undergoing CP were identified. The...Читать далее »

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 »
