For the development of autoimmune hepatitis (AIH), genetic predisposition and environmental triggers are of major importance. Although experimental AIH can be induced in genetically susceptible mice, the low precursor frequency of autoreactive T cells hampers a deeper analysis of liver-specific T cells. Here, we established a system where the model antigen hemagglutinin (HA) is expressed exclusively in hepatocytes of Rosa26-HA mice following administration of a replication deficient adenovirus expressing Cre recombinase (Ad-Cre)...

BACKGROUND: Sedatives or analgesics are widely used to relieve a patient's discomfort during colonoscopy (CS). Although cardiopulmonary adverse events are sometimes experienced during the examination, the risk factors for vital signs fluctuation (VSF) have not been fully elucidated. This study thus aimed to identify the risk factors for VSF during the examination, as well as to evaluate the frequency and the degree of VSF. SUMMARY: A total of 755 consecutive subjects who received CS under endoscopist-administrated sedation using midazolam, meperidine, or combination of both were retrospectively analyzed...

Karl-Uwe Petersen
BACKGROUND: Functional dyspepsia is a heterogeneous disorder lacking an established therapeutic strategy. Historical treatment attempts with pepsin products were shrugged off, as a simple calculation shows that quantitative substitution is pointless. However, such attempts might have been right for the wrong reason. SUMMARY: Today, the role of pepsins is primarily seen in the provision of signalling amino acids (especially phenylalanine and tryptophan) and peptides, which initiate processes promoting digestion...

BACKGROUND/AIMS: The 5-year postoperative follow-up for patients undergoing curative treatment for colorectal cancer (CRC) is labour intensive. We assessed the added value of a dedicated nonphysician clinician (NPC) in the follow-up of patients after resection for CRC. METHODS: Patients were divided into 2 groups as defined by the number of follow-up visits in the first year, including intensive (≥3×) and minimal (≤2×). Involvement of an NPC, diagnosis of disease recurrence and the course of the disease were determined...

BACKGROUND: Injury resistance occurring in the setting of liver fibrosis is an interesting phenomenon not yet well characterized. In the present study, we investigated dynamically the injury resistance against acute challenge using animal models of hepatic fibrosis and spontaneous resolution, and focused on high-mobility group box-1 (HMGB1), an important proinflammatory mediator. METHODS: The hepatic damage of control, fibrosis (CCl4, 6 weeks), and regressive mice with or without CCl4 challenge was dynamically observed and compared...

BACKGROUND: Commonly used medications including statins, metformin, and proton pump inhibitors (PPIs) effectively reduce the risk of esophageal, gastric, and colorectal cancer (CRC). SUMMARY: A number of observational studies and meta-analyses have shown that long-term statin use significantly reduces the incidence of gastrointestinal (GI) cancer. Moreover, statin use after GI cancer diagnosis has been significantly associated with better prognosis in large-scale cohort studies...

AIM: We aimed to investigate the factors that make inflammatory bowel disease (IBD) patients more or less likely to be willing to take corticosteroids. METHODS: Respondents completed a questionnaire. The primary outcome was whether the respondents would or would not use corticosteroids again to treat their IBD. Three separate univariate and multivariate analyses were performed to examine which variables predicted willingness to take steroids, including specific side effects...

BACKGROUND: In adults, infliximab (IFX) levels correlate with disease activity, and antibodies to IFX (ATIs) predict treatment failure. We aimed to determine the association of IFX levels and ATIs with disease activity in a paediatric population. We prospectively collected blood, stool, and clinical data from 65 patients (age 10.5-15.1 years) with Crohn's disease (CD) before IFX administration, and measured IFX trough levels, ATIs, and faecal calprotectin levels (CPT). Samples were collected during maintenance therapy...

Few data exist on differences in gut microbiota composition among principal gastrointestinal (GI) diseases. We evaluated the differences in gut microbiota composition among uncomplicated diverticular disease (DD), irritable bowel syndrome (IBS) and inflammatory bowel diseases (IBD) patients. DD, IBS, and IBD patients along with healthy controls (CT) were enrolled in our Italian GI outpatient clinic. Stool samples were collected. Microbiota composition was evaluated through a metagenomic gene-targeted approach...

BACKGROUND: Replication protein A (RPA) 3 is a subunit of the RPA protein complex, which functions in multiple processes of DNA metabolism. Dysregulation of RPA1 and RPA2 has been implicated in tumor progression in several cancer types. However, the function of RPA3 in hepatocellular carcinoma (HCC) tumorigenesis has not been elucidated. METHOD: In this study, we investigated the function of RPA3 in HCC development by stably knocking down its expression using short hairpin RNA (shRNA) in HepG2 cell line, followed by cell proliferation, colony formation, soft agar, and invasion assays...

BACKGROUND/AIM: Individual components of the metabolic syndrome (MS) such as obesity or diabetes mellitus impair the prognosis of patients with hepatocellular carcinoma (HCC) following curative treatment approaches or transarterial therapies. The aim of this retrospective study was to assess the impact of these factors on the overall survival (OS) of patients with advanced HCC treated with sorafenib. METHODS: Univariate and multivariate analyses were performed to assess the impact of individual components of the MS on the OS of 152 consecutive patients with advanced HCC treated with sorafenib...

BACKGROUND AND AIMS: Complications such as need for bowel resections and hospitalization due to Crohn's disease (CD) occur when disease activity persists due to ineffective therapy. Certain "high-risk" features require an early introduction of anti-tumor necrosis factor-α therapy to prevent such complications. We aim to evaluate the prevalence of "high-risk" features among a cohort of patients with CD and examine the association between discordance of early therapy with baseline risk stratification and disease outcome...

#14
Jing Shan, Hongjun Lei, Wei Shi, Xiaobin Sun, Yu Tang, Chunrong Ren
BACKGROUND: Whether gastric hyperchlorhydria and Helicobacter pylori infection contribute to aspirin-induced gastroduodenal injury still lacks evidence. Because serum pepsinogens (PGs) and gastrin-17 (G17) can reflect gastric acid secretion, this study intended to elucidate whether serum PGs, serum G17, and H. pylori infection are associated with aspirin-induced gastrointestinal injury. SUMMARY: A total of 60 patients taking low-dose aspirin for more than 1 month were enrolled in this study...

BACKGROUND: Creation of a J pouch is the gold standard surgical intervention in the treatment of chronic ulcerative colitis (UC). Pouchoscopy prior to ileostomy takedown is commonly performed. We describe the frequency, indication, and findings on pouchoscopy, and determine if pouchoscopy affects rates of complications after takedown. METHODS: All UC or indeterminate inflammatory bowel disease patients with a J pouch were retrospectively evaluated from January 1994 to December 2014...

BACKGROUND: The increased risk of gallstone has been reported in patients with ATP-binding cassette (ABC) transporter polymorphism. The half-transporters ABCG5 and ABCG8 mediate the efflux of cholesterol in hepatocytes and the intestine. We investigated whether ceramide plays a role in cholesterol efflux through the ABC transporters. METHODS: Six-week-old C57BL/6J mice were assigned to 3 groups. The normal group (n = 5) was fed a normal chow diet, the cholesterol group (n = 10) was fed a lithogenic diet, and the myriocin group (n = 15) was fed the lithogenic diet and myriocin, a specific inhibitor of serine-palmitoyl transferase...

BACKGROUND/AIM: We evaluated the relationship of hepatic function with repeated transarterial catheter chemoembolization (TACE) and prognosis after sorafenib treatment in various patient cohorts. METHODS: Study 1 comprised of 212 Barcelona clinic liver cancer stage-B (BCLC-B) HCC patients classified as Child-Pugh A (CP-A) and who had received repeated TACE treatments (r-TACE) (naïve:recurrence = 66:146). Study 2 comprised of 435 patients with unresectable HCC classified as CP-A in who sorafenib was introduced (naïve:recurrence = 37:398; CP score 5:6 = 282:153; macro-vessel invasion [MVI]+: extrahepatic metastasis [EHM]+ both negative = 124:226:143)...
