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.
