Background And Aim: A low hepatitis B surface antigen (HBsAg) level is reported to be predictive of future HBsAg seroclearance. A hospital-based cohort study was conducted to clarify the clinical features of patients with low HBsAg levels and to demonstrate the usefulness of low HBsAg levels for predicting HBsAg seroclearance.

Methods: A total of 1459 patients with chronic hepatitis B were included in the study.

Article Synopsis
  • Magnification endoscopy with narrow-band imaging (NBIME) and acetic acid enhancement (A-NBIME) helps visualize colorectal polyp structures and vascular patterns, and the study compares their diagnostic accuracy against traditional white light endoscopy (WLE).
  • In a sample of 628 colorectal polyps, A-NBIME had the highest diagnostic accuracy at 86.1%, while WLE and NBIME were at 80.8% and 79.3%, respectively.
  • A-NBIME also showed better reproducibility in diagnoses, with higher interobserver agreement (Fleiss's kappa value of 0.65) compared to WLE (0.43) and NBIME (0.52),

Background And Aim: The esophageal triamcinolone acetonide (TA)-filling method is a novel local approach for stenosis prevention after extensive esophageal endoscopic submucosal dissection (ESD). We evaluated this method after subcircumferential ESD.

Methods: We enrolled 20 patients with esophageal cancer requiring subcircumferential ESD in a prospective multicenter study.

In this study, we investigated a new class of artificial enzymes composed of Mn-porphyrin, imidazole, and cucurbit[10]uril (CB[10]) toward therapeutic antioxidants. Structural characterization by means of NMR indicated that the inclusion mode of metalloporphyrin in CB[10] was sensitive to the chemical structure of metalloporphyrin and that the structure of the artificial enzyme had a similarly to that of native heme catalase. Kinetic analysis for catalytic antioxidative activities demonstrated that the artificial enzyme exhibited highly efficient activity for HO disproportionation (catalase activity) in water.

Background And Aims: Endoscopic submucosal dissection (ESD) for extensive esophageal carcinomas may cause severe stenosis requiring endoscopic balloon dilations (EBDs). A standard prevention method has not been established. We propose the esophageal triamcinolone acetonide (TA)-filling method as a novel local steroid administration procedure.

An 80-year-old woman with a history of chronic hepatitis B was referred to our hospital because of upper gastrointestinal bleeding of unknown origin. Dynamic computed tomography revealed liver cirrhosis and hepatofugal collateral vessels around the duodenum. Emergency esophagogastroduodenoscopy showed duodenal varices with an erosive spot, highly suggestive of a variceal rupture site.

Background And Study Aims: Magnification endoscopy with narrow-band imaging (NBIME) and NBIME with acetic acid enhancement (A-NBIME) visualize the capillary and microstructure patterns of the gastric mucosal surface, respectively. This study aimed to compare the diagnostic accuracy and interobserver agreement for white-light endoscopy (WLE), NBIME, and A-NBIME in the different histologic types of gastric mucosal neoplasm.

Patients And Methods: Consecutive gastric neoplasms (n = 220; 49 adenomas, 144 differentiated adenocarcinomas, and 27 undifferentiated adenocarcinomas) were photographed with WLE, NBIME, and A-NBIME.

It has been reported that elderly patients with chronic hepatitis C infection cannot tolerate standard combination therapy. In this randomized, controlled trial, the efficacy and safety of peginterferon alpha-2b plus a low and escalating dose of ribavirin in chronic hepatitis C patients with high viral load genotype 1 were investigated. Sixty-two patients were randomized into combination therapy with standard ribavirin dosing (group 1) or low and escalating ribavirin dosing (group 2).

Background & Aims: Roles of alcohol consumption in non-alcoholic fatty liver disease are still controversial, although several cross-sectional studies have suggested the beneficial effect of light to moderate drinking on fatty liver. We analyzed the longitudinal relationship between drinking pattern and fatty liver.

Methods: We included 5297 Japanese individuals (3773 men and 1524 women) who underwent a baseline study in 2003 and follow-up at least once from 2004 to 2006.

Background And Goals: Pit pattern (PP) analysis of colorectal neoplasms using magnification chromoendoscopy with crystal violet (CV-MCE) is useful for predicting histologic features, but it is time consuming. Capillary pattern analysis by magnification endoscopy with narrow-band imaging (NBIME) is a useful and simpler procedure, but its diagnostic accuracy may be inferior to CV-MCE. NBIME with acetic acid enhancement (A-NBIME) is effective for rapid visualization of gastric mucosal microstructures.

We report a case of adenocarcinoma of the small intestine responding to XELOX chemotherapy, leading to a partial metabolic response(PMR). The patient was a 58-year-old male with multiple peritoneal dissemination of adenocarcinoma of the small intestine. Chemotherapy with XELOX(L-OHP 130 mg/m² on day 1 , and capecitabine 1,000 mg/m2 on days 1-14)was performed.

A 50-year-old man with a history of alcohol intake exceeding 80 g/day was admitted because of severe liver dysfunction and high fever. A rapid increase of transaminase with remittent high fever was observed several days after admission. Abdominal CT scan demonstrated a 22×20 mm mass in segment 8, highly suggestive of hepatocellular carcinoma.

Background/aims: The aim of this study is to elucidate the effectiveness of radiofrequency ablation (RFA) for the treatment of metastatic liver cancers.

Methodology: From 74 patients with metastatic liver cancers treated by RFA, 40 patients including 23 colon cancer who had received curative resection of the primary tumor were analyzed.

Results: Recurrence of the tumor was observed in 29 (72.

Purpose: Recent routine testing for liver function and anti-mitochondrial antibodies has increased the number of newly diagnosed patients with primary biliary cirrhosis (PBC). This study investigated the prognosis of asymptomatic PBC patients, focusing on age difference, to clarify its effect on the prognosis of PBC patients.

Methods: The study was a systematic cohort analysis of 308 consecutive patients diagnosed with asymptomatic PBC.

Aim: To evaluate the effectiveness of endoscopic submucosal dissection using an insulation-tipped diathermic knife (IT-ESD) for the treatment of patients with over 20 mm early gastric cancer (EGC).

Methods: A total of 112 patients with over 10 mm EGC were treated with IT-ESD at Sumitomo Besshi Hospital and Shikoku Cancer Center in the 5 year period from January 2002 to December 2006, including 40 patients with over 20 mm EGC. We compared patient backgrounds, the one-piece resection rate, complete resection (CR) rate, operation time, bleeding rate, perforation rate between patients with over 20 mm EGC [over 20 mm group (21-40 mm)] and the remaining patients (under 20 mm group).

Objective: The aim of this study was to determine the association between pretreatment intrahepatic mRNA levels of interferon receptor and interferon-stimulated genes and response to interferon therapy for genotype 1b chronic hepatitis C.

Methods: Forty-four patients with genotype 1b chronic hepatitis C who underwent liver biopsy and then received interferon therapy participated in this study. Pretreatment intrahepatic mRNA levels of interferon receptor genes (IFNAR1, IFNAR2b, and IFNAR2c) and interferon-stimulated genes (OAS1 and PKR) were quantified by competitive polymerase chain reaction.

To improve the efficacy of interferon (IFN) treatment for chronic hepatitis C, we have proposed the twice-daily administration of IFN-beta as a promising induction therapy. In this study, we demonstrated differences between the clearance of circulating HCV-RNA and the induction of anti-viral actions during the first 2 weeks of treatment. Nine patients with a high viral load and genotype 1b were randomly assigned to 3 groups: group A received 3MU of IFN-beta twice a day at intervals of 5 and 19 h; group B received 3MU of IFN-beta twice a day at intervals of 10 and 14 h; group C received 6MU of IFN-alpha once a day with ribavirin.

The hepatitis B virus (HBV) gene has been detected in hepatocellular carcinoma (HCC) tissue negative for the hepatitis B surface antigen and positive for the hepatitis C virus (HCV) antibody, but the precise role of the HBV gene in hepatocarcinogenesis has yet to be clarified. We studied the HBV gene in liver tissue several years before the emergence of HCC. Eleven patients diagnosed with HCV-positive chronic liver disease and who developed HCC were assigned to group A.
