BACKGROUND Northern Iran (Ardabil) is characterized by a high gastric cancer (GC) rate, whereas Southern Iran (Kerman and Yazd) has a low GC rate. The aim of this study is to verify the potential for pepsinogen I and II to detect atrophic gastritis (AG) in both high and low risk populations for GC. METHODS Sera of blood donors and patients with GC from Ardebil, Kerman and Yazd were used to me...
BACKGROUND The clinical significance of Helicobacter pylori antibody titer has been controversial, and the association between the extent of gastric atrophy or acid secretion and H. pylori antibody concentration has not been elucidated. MATERIALS AND METHODS Serum pepsinogen, H. pylori antibody concentration, and fasting gastric pH (as an indicator of acid secretion) were measured in 231 pati...
BACKGROUND AND OBJECTIVE Pepsinogen levels in plasma are increased by inflammation in the gastric mucosa, including inflammation resulting from Helicobacter pylori infection. A decrease in pepsinogen II level has been suggested as a reliable marker to confirm the successful eradication of infection. The aim of our study was to evaluate the potential role of pepsinogens I and II, gastrin-17 and ...
OBJECTIVE Ghrelin is mainly secreted by the gastric oxyntic mucosa and its production is impaired in chronic atrophic gastritis. This study aimed at evaluating how serum total ghrelin correlates with the extent of atrophy, and to compare its performance as a serologic marker with that of pepsinogen (PG). MATERIAL AND METHODS Data were collected from 154 patients with atrophic gastritis. The h...
Aim. Chronic gastritis was assessed serologically, endoscopically and histologically to identify correlations between these methods. Methods. Subjects comprised 319 patients who had provided informed consent. Serological assessment of chronic gastritis was based on the pepsinogen test method. Endoscopic gastritis and histological gastritis were assessed and scored according to the Kimura-Takemo...
In order to evaluate the relationship between Helicobacter pylori (H. pylori) infection and dietary preference, a cross-sectional study was performed among 626 residents in a rural area of Japan. Seropositive rates were 88.7% in males and 71.4% in females, and these increased with age for both sexes [male P < 0.05 and female P < 0.01]. The relationship between H. pylori-seropositivities and sal...
Chronic atrophic gastritis, which is thought to be a high risk for gastric cancer, can be diagnosed by serum pepsinogen levels. We compared the usefulness of the measurement of pepsinogen levels and indirect photofluorography as indicators of gastric cancer in a mass screening involving 5,620 Japanese subjects (mean age: 60.1 years old; male : female = 2,268 : 3,352) in 1991 and 1992. Subjects ...
Background Gastric cancer is the fifth most common malignancy in the world with almost one million new cases annually. Helicobacter pylori infection causes 89% of all gastric cancers. Premalignant lesions (atrophy and intestinal metaplasia) develop after several decades of inflammation. Secondary prevention with gastroscopy is possible, but it is costly and has a low compliance rate. Alternativ...
