AEE is not a rare condition, and constitutes 14.5% of the asymptomatic population. Male sex, hiatus hernia, and H. pylori infection are factors associated with AEE. These findings are not only helpful in identifying such asymptomatic patients, but also provide information to improve understanding of the relationship between H. pylori infection, reflux symptoms, and erosive esophagitis.
FIB-4 could predict hepatic fibrosis in CHC patients. By adding two parameters (age and alanine aminotransferase), FIB-4 better predicts advanced fibrosis and cirrhosis than APRI in CHC patients.
Background Although chronic liver disease is associated with gastroesophageal reflux disease (GERD), the impact of chronic hepatitis B virus (HBV) infection on this association remains unclear. We thus aimed to evaluate the relationship between chronic HBV infection and GERD.Methods In this prospective population-based study, 1,001 adult subjects who underwent an upper gastrointestinal endoscopic examination in a health check-up and completed a gastroesophageal reflux questionnaire were consecutively enrolled. Endoscopic findings were classified according to the Los Angeles classification. Hepatitis B surface antigen was used as a marker of HBV infection. Univariate and multivariate approaches were used to evaluate the effects of chronic HBV infection on GERD.Results Chronic HBV infection was associated with heartburn sensation [odds ratio (OR) 1.27, 95% confidence interval 1.01-1.61, P = 0.037], and erosive esophagitis (adjusted OR 1.75, 1.03-2.97, P = 0.037). Although male gender is a risk factor of erosive esophagitis, further analyses stratified by gender and aspartate aminotransferase to platelet ratio index (APRI) showed that chronic HBV infection was associated with erosive esophagitis in female subjects (adjusted OR 2.70, 1.14-6.39, P = 0.024) and those with APRI of more than 0.3 (adjusted OR 3.94, 1.73-8.96, P = 0.001). Moreover, higher serum aspartate aminotransferase (AST) and triglyceride (TG) levels were risk factors of erosive esophagitis in patients with chronic HBV infection. Conclusions Our findings indicate a close association between chronic HBV infection and GERD, especially in female subjects and those with higher APRI levels. Moreover, HBV carriers with higher AST or TG levels have higher incidence of erosive esophagitis. The interactions between chronic HBV infection and GERD need further studies.
The baseline serum qHBsAg level can predict virologic response in entecavir-treated CHB patients. However, a significant decline in the qHBsAg level cannot predict serologic or virologic response of entecavir treatment.
Non-alcoholic fatty liver disease is associated with an increased risk of metabolic and cardiovascular diseases. Whether the severity of fatty liver on ultrasound correlates with metabolic or cardiovascular risk remains unclear. A total of 1000 people receiving health examinations were enrolled, and 126 were excluded due to the presence of HBsAg, anti-HCV, known hepatic disorders or alcohol use (>140 g/wk). Significant fatty liver consisted of moderate and severe fatty liver on ultrasound. The definition of central obesity was modified to a waist circumference of >90 cm in men and >80 cm in women. Framingham risk score was used to estimate the risk of cardiovascular disease. A total of 874 subjects (485 women and 388 men with a mean age of 52.07 ± 11.68 years) were included in the final analysis. By using logistic regression analyses stratified by gender, the odds ratio for the prevalence of diabetes mellitus, metabolic syndrome and risk of cardiovascular disease increased with increasing fatty liver status in both genders (p ≤ 0.001). The difference was not only present between individuals with fatty liver vs. non-fatty liver but also between the mild fatty liver and significant fatty liver groups (p < 0.05). In conclusion, the severity of fatty liver on ultrasound could be useful for the risk stratification of metabolic syndrome, diabetes mellitus and cardiovascular disease in clinical practice.
Ultrasonography could assess the severity of hepatic steatosis with moderate accuracy. Obese patients are difficult ultrasonographically. In addition, age and hepatic fibrosis could affect the performance of ultrasonography in assessing the severity of hepatic steatosis.
Gastroesophageal reflux disease (GERD) is diagnosed based on typical symptoms in clinical practice. It can be divided into two groups using endoscopy: erosive and nonerosive reflux disease (NERD). This study aims to determine the risk factors of reflux symptoms and mucosal injury. This was a two-step case-control study derived from a cohort of 998 individuals having the data of reflux disease questionnaire (RDQ) and endoscopic findings. Those with minor reflux symptoms were excluded. The first step compared symptomatic GERD patients with healthy controls. The 2(nd) step compared patients with erosive esophagitis with healthy controls. In this study, the prevalence of symptomatic GERD and erosive esophagitis were 163 (16.3%) and 166 (16.6%), respectively. A total of 507 asymptomatic individuals without mucosal injury of the esophagus on endoscopy were selected as healthy controls. Compared with healthy controls, multivariate analyses showed that symptomatic GERD patients had a higher prevalence of hypertriglyceridemia [odds ratio (OR), 1.83; 95% confidence interval (CI) 1.13-2.96] and obesity (OR, 1.85; 95% CI 1.08-3.02). By contrast, male sex (OR, 2.24; 95% CI 1.42-3.52), positive Campylo-like organism (CLO) test (OR, 0.56; 95% CI 0.37-0.84), and hiatus hernia (OR, 14.36; 95% CI 3.05-67.6) were associated with erosive esophagitis. In conclusion, obesity and hypertriglyceridemia were associated with reflux symptoms. By contrast, male sex, negative infection of Helicobacter pylori, and hiatus hernia were associated with mucosal injury. Our results suggested that risk factors of reflux symptoms or mucosal injury might be different in GERD patients. The underlying mechanism awaits further studies to clarify.
