Cancer development based on chronic active gastritis and resulting gastric atrophy as assessed by serum levels of pepsinogen and Helicobacter pylori antibody titer.

Our study investigated the relationship between gastric cancer development and activity of Helicobacter pylori-associated chronic gastritis or the resulting chronic atrophic gastritis (CAG). A cohort of 4,655 healthy asymptomatic subjects, in whom serum pepsinogen (PG) and H. pylori antibody titer had been measured to assess the activity and stage of H.

Habitual coffee consumption inversely associated with metabolic syndrome-related biomarkers involving adiponectin.

Objectives: The goal of this cross-sectional study was to assess whether habitual coffee consumption shows beneficial association with metabolic syndrome (MetS) in adults.

Methods: The association of coffee consumption and MetS-related biomarkers including visceral fat area (VFA) and subcutaneous fat area (SFA), total serum adiponectin (T-Ad), low-molecular-weight serum adiponectin (LMW-AD), medium-molecular-weight serum adiponectin (MMW-Ad), and high-molecular-weight serum adiponectin (HMW-Ad) levels were analyzed among 364 Japanese men (36-61 y old) using two models of multivariate regression analyses; model 1 (adjusted for age, alcohol drinking, smoking, and walking status) and model 2 (adjusted for body mass index in addition to model 1 analysis). Participants were categorized into two groups according to their MetS risk score (raised blood pressure and hemoglobin A1c levels, and reduced high-density lipoprotein cholesterol levels).

Relationship between vomiting reflex during esophagogastroduodenoscopy and dyspepsia symptoms.

Aim: Although frequent vomiting reflexes during esophagogastroduodenoscopy (EGD) causes suffering in patients, very few studies have investigated the characteristics of subjects who frequently develop vomiting reflexes. This study examined the incidence of the vomiting reflex and related factors, especially upper gastrointestinal symptoms, among individuals undergoing transoral EGD.

Methods: Subjects included 488 consecutive adults (mean age, 56.

Development of gastric cancer in nonatrophic stomach with highly active inflammation identified by serum levels of pepsinogen and Helicobacter pylori antibody together with endoscopic rugal hyperplastic gastritis.

This study aimed to elucidate groups at high risk of developing cancer among patients with serologically identified Helicobacter pylori infection and nonatrophic stomach. Annual endoscopy was performed for a mean of 5.4 years in 496 asymptomatic middle-aged men who were H.

Assessment of gastroesophageal reflux disease by serodiagnosis of Helicobacter pylori-related chronic gastritis stage.

Aim: To evaluate the association of Helicobacter pylori (H.pylori)-related chronic gastritis stage with upper gastrointestinal symptoms and gastroesophageal reflux disease (GERD).

Methods: Subjects underwent upper gastrointestinal endoscopy, a questionnaire using a frequency scale for symptoms of GERD (FSSG), and measurements of serum H.

Elevated risk of colorectal adenoma with Helicobacter pylori-related chronic gastritis: a population-based case-control study.

This study investigated correlations between Helicobacter pylori infection or chronic atrophic gastritis (CAG) and risk of colorectal adenoma in a population-based case-control study. Subjects comprised asymptomatic, middle-aged, male Japanese factory workers who participated in an annual health check-up program, including cancer screening with colonoscopy. We selected 239 colorectal adenoma cases based on histological evaluation and 239 age-matched adenoma-free controls, and evaluated colorectal adenoma risk according to stage of H.

Preventive effects of etodolac, a selective cyclooxygenase-2 inhibitor, on cancer development in extensive metaplastic gastritis, a Helicobacter pylori-negative precancerous lesion.

The present study investigated the preventive effects of etodolac, a selective cyclo-oxygenase (COX)-2 inhibitor, on metachronous cancer development after endoscopic resection of early gastric cancer. Among 267 early gastric cancer patients who underwent endoscopic resection, 47 patients with extensive metaplastic gastritis were selected based on endoscopic findings and our previously described criteria of serum pepsinogen (PG) test-positive and Helicobacter pylori antibody-negative conditions. Nonrandomized etodolac treatment (300 mg/day) was administered to 26 patients (Group A), while the remaining 21 patients were untreated (Group B).

Eradication of Helicobacter pylori prevents cancer development in subjects with mild gastric atrophy identified by serum pepsinogen levels.

A longitudinal cohort study was conducted in Helicobactor pylori-infected middle-aged Japanese males to evaluate the preventive effects of H. pylori eradication on the development of gastric cancer according to the extent of chronic atrophic gastritis (CAG). The extent of CAG was monitored by baseline serum pepsinogen (PG) levels.

Risk of gastric cancer in asymptomatic, middle-aged Japanese subjects based on serum pepsinogen and Helicobacter pylori antibody levels.

A total of 5,209 asymptomatic, middle-aged subjects, whose serum pepsinogen (PG) and Helicobacter pylori antibody levels had been assessed, were followed for 10 years. Subjects with positive serum H. pylori antibodies (>50 U/mL) had an increased cancer risk (HR = 3.

Cancer high-risk subjects identified by serum pepsinogen tests: outcomes after 10-year follow-up in asymptomatic middle-aged males.

Background: Gastric cancer screening using the pepsinogen filter test is receiving wide recognition in Japan owing to convenience, freedom from discomfort or risk, efficiency, and economy. Because the long-term outcomes of cancer development in extensive atrophic gastritis detected by pepsinogen test are unclear, test-positive and test-negative subjects were investigated in a longitudinal cohort study.

Methods: Subjects comprised 5,209 middle-aged men with measured serum pepsinogen levels who were followed for 10 years.

Serum pepsinogen and gastric cancer screening.

Since the 1990's, the test for serum pepsinogen as a marker for chronic atrophic gastritis has been incorporated into gastric cancer screening programs, on a trial basis, to identify people at high risk for gastric cancer. The addition of the serum test to the cancer screening program has been shown to improve the detection rate of cancer and pepsinogen testing is useful in detecting early-stage gastric cancers arising from atrophic gastric mucosa, which macroscopically tend to be elevated and histologically differentiated. Furthermore, the cost for the detection of a single cancer case is much less than that for conventional screening.

Gastric cancer screening of a high-risk population in Japan using serum pepsinogen and barium digital radiography.

With the aim of developing more efficient gastric cancer screening programs for use in Japan, we studied a new screening program that combines serum pepsinogen (PG) testing and barium digital radiography (DR). A total of 17 647 middle-aged male subjects underwent workplace screening over a 7-year period using a combination of PG testing and DR. This program's effectiveness, as well as other characteristics of the program, was analyzed.
