Exploring Clinical Characteristics of Liver Disease Patients Based on Digestive Metabolic Exhaled Air

Sponsor: Shanghai Zhongshan Hospital

Summary

Cirrhosis is a common digestive system disease and represents the final stage of the progression of various chronic liver diseases. During cirrhosis, the intestinal microenvironment is affected due to liver damage and increased portal venous pressure. Displacement of gut microbiota is closely related to the occurrence and development of cirrhosis. Disruption of the gut microbiota is associated with changes in the levels of nitric oxide (NO), hydrogen (H₂), methane (CH₄), and hydrogen sulfide (H₂S). Breath testing is an emerging method for assessing gut microbiota. This project aims to investigate the characteristics and prognosis of patients with chronic liver disease by detecting exhaled breath markers such as nitric oxide (NO), hydrogen (H₂), methane (CH₄), and hydrogen sulfide (H₂S), in conjunction with results from serological tests, gut microbiota analysis, and radiomics. The goal is to identify new diagnostic biomarkers and therapeutic targets, to recognize high-risk patients at an early stage, and to improve patient survival rates and quality of life.
