Brief summary

Despite advances in gastrointestinal endoscopy and pharmaceuticals, gastrointestinal bleeding is still a significant emergency disease with a high mortality rate of 1.9-5 per 100 people due to excessive bleeding and shock. There are several indicators using pulse rate, blood pressure, hemoglobin, etc. to select patients who require endoscopic intervention, or hospitalization, but these are inaccurate and with a high false-positive rate and low specificity at 35-40%. Therefore, tests with high diagnostic accuracy for gastrointestinal bleeding patients are required and findings specific biomarkers for gastrointestinal bleeding are of great importance.

Detailed description

Recently, with the development of metabolomics, efforts are being made to improve the diagnosis and treatment of diseases through metabolomics analysis, but there are no studies related to gastrointestinal bleeding. If the degradation/metabolism process of blood that accumulates in the gastrointestinal tract is well studied and understood, there is a possibility of finding specific biomarkers for gastrointestinal bleeding. Thus, this study aims to analysis of metabolomics of blood degradation/digestion using in vitro digestion model to identify potential biomarkers of gastrointestinal bleeding.
