| Study Title | Cirrhosis-related metabolomics study |
| Study Summary | There are limited data on the diagnostic accuracy of gut microbial signatures for predicting hepatic decompensation in patients with cirrhosis. The aim of this study is to determine whether a stool genomic and metabolic signature accurately detects hepatic decompensation and mortality risk in cirrhosis secondary to nonalcoholic fatty liver disease (NAFLD). Shotgun metagenomic sequencing was performed on fecal samples collected from a prospective cohort of adults with NAFLD-related cirrhosis. The signatures were further validated with a metabolomic study on serum samples. Finally, we developed a Random Forest machine learning algorithm to make predictions on hepatic decompensation and mortality in NAFLD-related cirrhosis. Here we uploaded the metabolomics study data from LC-MS/MS. |
