Clinical and endoscopic features of Chinese reflux esophagitis patients

AIM： To analyze the clinical and endoscopic features of Chinese patients with reflux esophagitis （RE）. METHODS： A total of 1405 RE patients were analyzed retrospectively. Data on gender, age, presence/absence of H pylori infection and associated esophageal hiatal hernia were collected. Esophagitis was divided into different grades according to Los Angeles Classification. RESULTS： Of 18823 patients, 1405 were diagnosed as RE. The ratio of male to female patients was 1.75：1 （P 〈 0.01）. The mean age of male and female patients was significantly different （P = 0.01）. The peak age at onset of the disease was 40-60 years. According to Los Angeles Classification, there were significant differences in the age of patients with grades A and B compared to patients with grades C and D （P 〈 0.01）. Two hundred and seventy-seven patients were infected with H pyiorl, the infection rate was low （P 〈 0.01）. Complication of esophageal hiatal hernia was found to be significantly associated with the severity of esophagitis and age in 195 patients （P 〈 0.01）. Esophageal mucosa damages were mainly located at the right esophageal wall. CONCLUSION： The peak age of onset of RE is 40-60 years and higher in males than in females. The mean age of onset of RE is lower in males than in females. The infection rate of Hpylori is significantly decreased in patients with esophagitis. Old age and esophageal hiatal hernia are associated with more severe esophagitis. Right esophageal mucosal damage can occur more often in RE patients.     

A community-based epidemiological study of elevated serum alanine aminotransferase levels in Kinmen, Taiwan

AIM: To explore any gender-related differences in prevalence of and condition-associated factors related to an elevated serum alanine aminotransferase (ALT) level amongst residents of Kinmen, Taiwan. METHODS: A total of 11 898 of a potential 20 112 regional residents aged 30 years or more completed a related questionnaire that was carried out by the Yang-Ming Crusade between 1991 and 1994 inclusively, with blood samples being collected by public nurses. The overall questionnaire response rate was 59.3% (52.4% for males and 66.0% for females). RESULTS: The prevalence of an elevated serum ALT level for this sub-population was found to be 7.2%, the prevalence revealing a statistically significant decrease with increasing population age (P<0.0001). Males exhibited a greater prevalence of elevated serum ALT level than did females (9.4% vs 5.3%, P<0.0001). Using multiple logistic regression analysis, in addition to male gender, a younger age, greater waist circumference, presence of type-2 diabetes and hyperuricemia were the significant factors associated with an elevated serum ALT level for both males and females. Gender-related differences as regards associated factors were also revealed. For males, obesity was significantly related to an elevated serum ALT level (OR = 1.28, 95%CI: 1.00-1.66) but this was not so for females (OR = 1.09, 95%CI: 0.84-1.42). Hypertriglyceridemia (OR = 1.80, 95%CI: 1.36-2.39) and hyperuricemia (OR = 1.61, 95%CI: 1.03-2.52) were significantly related to elevated serum ALT levels only for females. CONCLUSION: Several gender-related differences were noted pertaining to the prevalence of and relationship between obesity, hypertriglyceridemia and hyperuricemia and elevated serum ALT level in the present study.     

Prevalence of gastroesophageal reflux symptoms in a large unselected general population in Japan

AIM：To examine the prevalence of gastroesophageal reflux disease （GERD） symptoms in a large unselected general population in Japan.
METHODS： In Japan, mature adults are offered regular check-ups for the prevention of gastric cancer. A notice was sent by mail to all inhabitants aged 〉 40 years. A total of 160 983 Japanese （60 774 male, 100 209 female; mean age 61.9 years） who underwent a stomach check up were enrolled in this study. In addition, from these 160 983 subjects, we randomly selected a total of 82 894 （34 275 male, 48 619 female; mean age 62.4 years） to evaluate the prevalence of abdominal pain. The respective subjects were prospectively asked to complete questionnaires concerning the symptoms of heartburn, dysphagia, and abdominal pain for a 1 mo period.
RESULTS： The respective prevalences of the symptoms in males and females were： heartburn, 15.8% vs 20.7%; dysphagia, 5.4% vs 7.8%; and abdominal pain, 6.6% vs 9.6%. Among these symptoms, heartburn was significantly high compared with the other symptoms, and the prevalence of heartburn was significantly more frequent in females than in males in the 60-89-year agegroup. Dysphagia was also significantly more frequent in female patients.
CONCLUSION： The prevalence of typical GERD symptoms （heartburn） was high, at about 20% of the Japan population, and the frequency was especially high in females in the 60-89 year age group.     

Clinical epidemiology of gastric cancer in Hehuang valley of China:A 10-year epidemiological study of gastric cancer

AIM:To investigate the clinical epidemiological characteristics of gastric cancer in the Hehuang valley,China,to provide a reference for treatment and prevention of regional gastric cancer.METHODS:Between February 2003 and February2013,the records of 2419 patients with gastric cancer were included in this study.The patient’s characteristics,histological and pathological features,as well as the dietary habits of the patients,were investigated.RESULTS:The clinical data showed that adenocarcinoma was the leading histological type of gastric cancer in this area.Characteristics of gastric cancer in different ethnic groups and age showed that the 60.55-65.50years group showed the high incidence of gastric cancer in all ethnic groups.There were more male gastric cancer patients than female.Intestinal was the most common type of gastric cancer in the Hehuang valley.There was no significant difference in the proportion of sex in terms of Helicobacter pylori infection.The impact of dietary habits on gastric cancer showed that regular consumption of fried or grilled food,consumption of high-salt,high-fat and spicy food and drinking strong Boiled brick-tea were three important factors associated with gastric cancer in males and females.CONCLUSION:Differences existed in race,sex,and age of patients according to the epidemiology of gastric cancer in the Hehuang valley.Moreover,dietary habits was also an important factor contributing to gastric cancer.

Clinicopathologic and molecular features associated with patient age in gastric cancer

AIM: To compare characteristics and prognosis of gastric cancer based on age.METHODS: A retrospective study was conducted on clinical and molecular data from patients(n =1658) with confirmed cases of gastric cancer in Seoul National University Bundang Hospital(Seoul, South Korea) from 2003 to 2010 after exclusion of patients diagnosed with lymphoma, gastrointestinal stromal tumor, and metastatic cancer in the stomach. DNA was isolated from tumor and adjacent normal tissue,and a set of five markers was amplified by polymerase chain reaction to assess microsatellite instability(MSI). MSI was categorized as high, low, or stable if ≥ 2, 1, or 0 markers, respectively, had changed.Immunohistochemistry was performed on tissue sections to detect levels of expression of p53, human epidermal growth factor receptor(HER)-2, and epidermal growth factor receptor. Statistical analysis of clinical and molecular data was performed to assess prognosis based on the stratification of patients by age(≤ 45 and 45 years).RESULTS: Among the 1658 gastric cancer patients, the number of patients with an age ≤ 45 years was 202(12.2%; 38.9 ± 0.4 years) and the number of patients 45 years was 1456(87.8%; 64.1 ± 0.3 years).Analyses revealed that females were predominant inthe younger group(P 0.001). Gastric cancers in the younger patients exhibited more aggressive features and were at a more advanced stage than those in older patients. Precancerous lesions, such as atrophic gastritis and intestinal metaplasia, were observed less frequently in the older than in the younger group(P 0.001). Molecular characteristics, including overexpression of p53(P 0.001), overexpression of HER-2(P = 0.006), and MSI(P = 0.006), were less frequent in gastric cancer of younger patients. Cancer related mortality was higher in younger patients(P= 0.048), but this difference was not significant after adjusting for the stage of cancer.CONCLUSION: Gastric cancer is distinguishable between younger and older patients based on both clinicopathologic and molecular features, but stage is the most important predictor of prognosis.
