Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The objective of this observational study is to compare the differences in proteomics and gut microbiome between the liver cirrhosis group without hepatic encephalopathy and the hepatic encephalopathy group through proteomics and microbiome analysis, screen out the characteristic proteomics and microbiome of patients with hepatic encephalopathy, guide clinical diagnosis and treatment, and conduct in-depth research on the pathogenesis of hepatic encephalopathy. The main questions it aims to answer are:

Are there any differences in serum proteomes between patients with liver cirrhosis without hepatic encephalopathy and those with hepatic encephalopathy? If so, what are the main protein differences? There are differences in the fecal microbiome between patients with liver cirrhosis without hepatic encephalopathy and those with hepatic encephalopathy? If so, what are the main microbial differences?

This study will screen for the differences in proteomes and gut microbiomes between patients with liver cirrhosis without hepatic encephalopathy and those with hepatic encephalopathy, and identify the characteristic proteomes and microbiomes of patients with hepatic encephalopathy to guide clinical diagnosis and treatment.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Liver cirrhosis non-hepatic encephalopathy group (NHE group)

Patients with liver cirrhosis aged ≥18 years, with normal blood ammonia; West-Haven classification 0, normal neurological signs, and normal neuropsychological tests; The patient agreed to participate and signed the informed consent form.

No interventions assigned to this group

Liver cirrhosis hepatic encephalopathy group (HE group)

Patients with liver cirrhosis aged 18 years or older, with elevated blood ammonia; Subclinical hepatic encephalopathy and West-Haven classification of grades 0, 1 to 4 HE, presenting with mental abnormalities such as personality and behavioral changes, and neurological abnormalities such as coma; Neurological signs are normal/flapping tremors can be elicited/positive neurological signs such as ankle clonus, and neuropsychological tests are abnormal; The patient/legal guardian agrees to participate and signs the informed consent form.

No interventions assigned to this group

Eligibility Criteria
