A Clinical Cohort Study on the Pathogen Spectrum of Hepatic Virus-caused Cirrhosis Complicated With Infection

March 1, 2024 updated by: Jiajia Chen, Zhejiang University

A Multicenter Prospective Clinical Cohort Study on the Pathogen Spectrum of Hepatic Virus-caused Cirrhosis Complicated With Infection

The goal of this observational study is to expound the population and characteristics of pathogenic microorganisms with co-infection, draw the pedigree of pathogenic microorganisms, and evaluate its influence on disease outcome in patients with hepatic virus-caused cirrhosis. The main questions it aims to answer are:

  • Describe the populations and characteristics of pathogenic microorganisms responsible for co-infections in patients with hepatic virus-caused cirrhosis.
  • Map the spectrum of pathogenic microorganisms, and evaluate their impact on disease regression.

Detailed Description

Cirrhosis is a chronic progressive disease caused by different etiological factors and characterized by diffuse hepatocellular degeneration and necrosis, abnormal regeneration of hepatocytes, intrahepatic neovascularization, massive proliferation of hepatic fibrotic tissues, and pseudofollicular formation. The number of patients with liver disease in China is about 300 million, and the number of deaths from cirrhosis accounts for 11% of the global deaths from cirrhosis. Its etiology is diverse, and hepatitis due to hepatophilic virus infection is still the main cause in China. A recent study by scholars on 11861 patients hospitalized for the first time due to liver cirrhosis in 50 hospitals in China showed that among the causes of liver cirrhosis in China, HBV infection accounted for 71.15% and HCV infection accounted for 8.12%. About two-thirds of patients with cirrhosis and extrahepatic organ failure suffer from sepsis. Infections increase the risk of death in patients with cirrhosis, and reports have shown that these patients are hospitalized for twice as long as patients without cirrhotic sepsis and have a hospital mortality rate of up to 50%. This study focuses on the impact of secondary infections on the clinical prognosis of cirrhosis, and proposes to establish a prospective, multicenter clinical cohort of secondary infections in cirrhosis, map infection pathogens, correlate the characteristics of the underlying immune status with the pathogen profiles of secondary infections, and set up an early warning system of secondary infection surveillance, with the aim of early prevention and early recognition of secondary infections, and improvement of prognosis for patients with liver cirrhosis.

Contacts and Locations

This section provides the contact details for those conducting the study, and information on where this study is being conducted.

Study Contact

Study Contact

The name and contact information for the person who can answer enrollment questions for a clinical study. Each location where the study is being conducted may also have a specific contact, who may be better able to answer those questions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Sampling Method

Design Details

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
quick SEPSIS RELATED ORGAN FAILURE ASSESSMENT(qSOFA) at 4 weeks
Time Frame: 4 weeks
qSOFA consists of 3 items: altered state of consciousness, systolic blood pressure ≤ 100 mmHg, and respiratory rate ≥ 22 respirations/min. 2 or more items, i.e., a qSOFA score of ≥ 2, are considered to be suspicious for sepsis.Higher qSOFA scores are associated with a higher risk of patient death.
4 weeks
Secondary infection in patients at 4 weeks
Time Frame: 4 weeks
Site of infection, pathogen results such as blood or body fluid pathogen cultures or Next-generation sequencing(NGS) results.
4 weeks

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.

Measure Description
Time Frame
Survival rate
Time Frame: 12 weeks
12-week survival in infected patients with viral hepatitis cirrhosis

Primary Completion (Estimated)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
