Investigation of the Prevalence of Hepatopulmonary Syndrome in Cirrhosis Patients Caused by Hepatitis B in Western China

February 9, 2018 updated by: Lu KZ, Southwest Hospital, China
to investigate the prevalence of hepatopulmonary syndrome in cirrhosis patients caused by Hepatitis B in western China

Study Overview

Status

Unknown

Detailed Description

Hepatopulmonary syndrome (HPS) occurs in approximately 4%-29% of cirrhotic patients and influences mortality. China has 100 million Hepatitis B virus (HBV) carriers and Chronic HBV infection is well-recognized risk factor for cirrhosis.But little is known about the prevalence of HPS in cirrhosis patients caused by HBV in western China. The aim of this study was to investigate the HPS incidence, and the signs, symptoms, arterial blood gas, and BMP9 in the serum of the patients.
