141. Complementary and Alternative Medicines Used by Patients With Inflammatory Bowel Diseases.

作者: Adam S Cheifetz.;Robert Gianotti.;Raphael Luber.;Peter R Gibson.
来源: Gastroenterology. 2017年152卷2期415-429.e15页
Patients and physicians often have many questions regarding the role of complementary and alternative medicines (CAMs), or nonallopathic therapies, for inflammatory bowel diseases (IBDs). CAMs of various forms are used by more than half of patients with IBD during some point in their disease course. We summarize the available evidence for the most commonly used and discussed CAMs. We discuss evidence for the effects of herbs (such as cannabis and curcumin), probiotics, acupuncture, exercise, and mind-body therapy. There have been few controlled studies of these therapies, which have been limited by their small sample sizes; most studies have been uncontrolled. In addition, there has been a lack of quality control for herbal preparations. It has been a challenge to design rigorous, randomized, placebo-controlled trials, in part owing to problems of adequate blinding for psychological interventions, acupuncture, and exercise. These barriers have limited the acceptance of CAMs by physicians. However, such therapies might be used to supplement conventional therapies and help ease patient symptoms. We conclude that physicians should understand the nature of and evidence for CAMs for IBD so that rational advice can be offered to patients who inquire about their use. CAMs have the potential to aid in the treatment of IBD, but further research is needed to validate these approaches.

Alterations in hepatic free fatty acid (FFA) uptake and metabolism contribute to the development of prevalent liver disorders such as hepatosteatosis. However, detecting dynamic changes in FFA uptake by the liver in live model organisms has proven difficult. To enable noninvasive real-time imaging of FFA flux in the liver, we generated transgenic mice with liver-specific expression of luciferase and performed bioluminescence imaging with an FFA probe. Our approach enabled us to observe the changes in FFA hepatic uptake under different physiological conditions in live animals. By using this method, we detected a decrease in FFA accumulation in the liver after mice were given injections of deoxycholic acid and an increase after they were fed fenofibrate. In addition, we observed diurnal regulation of FFA hepatic uptake in living mice. Our imaging system appears to be a useful and reliable tool for studying the dynamic changes in hepatic FFA flux in models of liver disease.

Adequate bowel preparation is an essential prerequisite for complete mucosal visualization during colonoscopy. Polyethylene glycol (PEG) solutions are commonly used. However the large volume of the solution is often poorly tolerated. Addition of Lubiprostone (LB) could improve the adequacy of standard PEG preparation & reduce requirement. The aims to assess adequacy of PEG preparation with addition of single dose LB (24mcg) vs placebo and efficacy of reduced dose PEG + LB compared with full dose PEG + LB.

Although elevated levels of lactoferrin provide a biomarker for inflammatory bowel diseases and colorectal cancer, the clinical significance of these elevated levels in ascitic fluid of patients with ascites caused by liver cirrhosis is limited. The aims of our study were to investigate the usefulness of ascitic fluid lactoferrin levels for the diagnosis of spontaneous bacterial peritonitis (SBP) in patients with cirrhosis and to evaluate the association between lactoferrin levels and the development of hepatocellular carcinoma (HCC).

Pathogenesis of Crohn's disease (CD) involves immune and microbial dysregulation, induced by environmental factors in genetically susceptible individuals. There are believed to be multiple subtypes of CD, which contributes to its observed clinical heterogeneity. This concept has been reinforced by recognition of the complexity of the genetic, microbial, immune, and environmental factors that affect risk for CD. Paneth cells mediate immunity and maintain the small intestinal epithelium; defects in activities of these cells have been observed in high proportions of patients with CD, and are associated with a more aggressive CD phenotype. Paneth cells integrate complex genetic, immune, and environmental signals, therefore alterations in their function could lead to different subtypes of CD, as observed in studies in cohorts of primarily European descent. Subtypes of CD associated with Paneth cell function have been observed even among patients from different genetic backgrounds. We discuss genetic susceptibility loci for CD and how these affect Paneth cell activity.

We have limited knowledge about the association between the composition of the intestinal microbiota and clinical features of irritable bowel syndrome (IBS). We collected information on the fecal and mucosa-associated microbiota of patients with IBS and evaluated whether these were associated with symptoms.

149. Innate Immune Cell Trafficking and Function During Sterile Inflammation of the Liver.

来源: Gastroenterology. 2016年151卷6期1087-1095页
The sterile inflammatory response (inflammation in the absence of infection) to tissue injury and cell death is required for normal wound healing. However, dysregulated sterile inflammation leads to various acute and chronic inflammatory diseases, including those of the liver and gastrointestinal tract. It is therefore important to increase our understanding of the mechanisms that control physiological versus pathological sterile inflammation. We have begun to clarify the cellular and molecular mechanisms that coordinate the innate immune response to tissue damage and cell death in the liver. In this review, we summarize the mechanisms that alert the immune system to the presence of tissue damage and highlight recent advances in our understanding of innate immune cell trafficking to sites of hepatic sterile inflammation. We explore the functions of various innate immune cells in the coordination of tissue repair, including previously underappreciated roles of peritoneal macrophages and platelets. We propose that dysregulation of immune cell trafficking or function at sites of tissue injury contributes to the misdirection of sterile inflammation to promote chronic inflammatory disease.

Alcoholic Hepatitis (AH) is major source of alcohol-related mortality and health care expenditures in the United States. There is insufficient information regarding the role of race and ethnicity on healthcare utilization and outcomes for patients with AH. We aimed to determine whether there are racial/ethnic differences in resource utilization and inpatient mortality in patients hospitalized with AH.

This study examines the dual role of Escherichia coli in the course of ulcerative colitis (UC). The intestinal microbiota is considered to play an important role in UC pathogenesis, but how E. coli contributes to inflammation in UC is still unknown. On the one hand, we demonstrated that there was a significant increase in the number of E. coli at the sites of inflammation in patients with UC, which can lead to immune system activation, whilst, on the other hand, E. coli may contribute to the resolution of inflammatory reactions since E. coli can inhibit hydroxyl radical formation by eliminating substrates of the Fenton reaction, by assimilating ferrous iron (Fe2+) and inducing the decomposition of hydrogen peroxide (H2O2). On this way, E. coli may affect the initiation and/or prolongation of remission stages of UC.

Esophageal squamous cell carcinoma (ESCC) is the commonest primary malignant esophageal tumor, which typically presents as endoscopically visible surface mucosal ulcerations, irregularities, or polyploidal masses. We here report a rare case of primary ESCC with completely intramural growth under a normal looking intact nondysplastic surface squamous epithelium disguising as a submucosal tumor. Upper gastrointestinal endoscopy-guided mucosal biopsy was negative for malignancy. Endoscopic ultrasound (EUS) revealed a heteroechoic solid mass originating from the muscularis propria of the distal esophagus. Cytological study of EUS-guided fine needle aspiration from the mass was suggestive of squamous cell carcinoma, which was confirmed on immunohistochemistry. There was no evidence of metastatic origin of this tumor or continuous cancer involvement from the surrounding structures, including the head, neck, and lungs on bronchoscopy, computed tomography scan, and positron emission tomography scan. Exclusive intramural squamous cell carcinoma with normal overlying mucosa is an exceedingly rare presentation of primary ESCC with only four cases reported in the literature so far. A high index of suspicion is required by the gastroenterologists and pathologists in diagnosing these cases as these tumors closely mimic the mesenchymal submucosal tumors such as lipoma, leiomyoma, and gastrointestinal stromal tumors. EUS is an indispensable tool in making a preoperative diagnosis and therapeutic decision making.

Strategies for management of inflammatory bowel diseases are shifting from simple control of symptoms toward full control of these diseases (clinical and endoscopic remission), with the final aim of blocking their progression and preventing bowel damage and disability. New goals have been proposed for treatment, such as treat to target and tight control based on therapeutic monitoring and early intervention. For patients who achieve clinical remission, there is often interest in discontinuation of therapy due to safety or economic concerns. We review the evidence supporting these emerging paradigms, the reasons that early effective treatment can alter progression of inflammatory bowel diseases, the importance of examining objective signs of inflammation, and the safety of reducing treatment dosage. We also discuss recent findings regarding personalization of care, including factors that predict patient outcomes and response to therapies, as well as preventative strategies.

154. Mechanisms, Management, and Treatment of Fibrosis in Patients With Inflammatory Bowel Diseases.

In the last 10 years, we have learned much about the pathogenesis, diagnosis, and management of intestinal fibrosis in patients with inflammatory bowel diseases. Just a decade ago, intestinal strictures were considered to be an inevitable consequence of long-term inflammation in patients who did not respond to anti-inflammatory therapies. Inflammatory bowel diseases-associated fibrosis was seen as an irreversible process that frequently led to intestinal obstructions requiring surgical intervention. This paradigm has changed rapidly, due to the antifibrotic approaches that may become available. We review the mechanisms and diagnosis of this serious complication of inflammatory bowel diseases, as well as factors that predict its progression and management strategies.

Patients infected with hepatitis C virus (HCV) genotype 1, 4, or 6, with or without cirrhosis, previously treated with peg-interferon and ribavirin, are a challenge to treat. We performed a phase 3 randomized controlled open-label trial to assess the effects of 12 or 16 weeks of treatment with once-daily elbasvir (an HCV NS5A inhibitor, 50 mg) and grazoprevir (an HCV NS3/4A protease inhibitor, 100 mg), in a fixed-dose combination tablet, with or without twice-daily ribavirin, in this patient population.

159. Role of vitamin D3 combined to alginates in preventing acid and oxidative injury in cultured gastric epithelial cells.

作者: Francesca Uberti.;Claudio Bardelli.;Vera Morsanuto.;Sabrina Ghirlanda.;Claudio Molinari.
来源: BMC Gastroenterol. 2016年16卷1期127页
Gastric diseases are a worldwide problem in modern society, as reported in the USA, in the range of 0.5-2 episodes/year/person and an incidence of 5-100 episodes/1000/week according to seasons and age. There is convincing evidence that oxidative stress is involved in the pathogenesis of acute gastric injury. Acid secreted from gastric parietal cells determines mucosal injuries which in turn cause inflammation and oxidative stress. Consequent inflammation produces free radicals by mitochondria thus causing lipid peroxidation, oxidative and acidic stress, which can lead to cell apoptosis. Vitamin D3, the active form of vitamin D, may counteract intracellular cell death and improve epithelial regeneration.

160. Faecal calprotectin: factors affecting levels and its potential role as a surrogate marker for risk of development of Crohn's Disease.

作者: Michael A Mendall.;Derek Chan.;Roshani Patel.;Devinder Kumar.
来源: BMC Gastroenterol. 2016年16卷1期126页
Faecal calprotectin (FC) is one of the most widely used non-invasive tests for the diagnosis and assessment of Crohn's disease (CD) activity. Despite this, factors other than disease activity which affect levels have not been extensively reviewed. This is of importance when using FC in the diagnostic setting but also may be of utility in studying the aetiology of disease.
