Cytokines and the Risk of Infection in Liver Cirrhosis (CLC-2009)

March 2, 2012 updated by: Vanessa Stadlbauer-Koellner, MD, Medical University of Graz

A Single-center, Open Study to Investigate Cytokine Levels in Patients With Hepatic Cirrhosis Before the Development of Significant Infection

The aim of this study is to test whether the oscillation of cytokine concentrations in serum is able to predict the development of infection in patients with liver cirrhosis.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Detailed Description

Patients with liver cirrhosis frequently develop bacterial, viral or fungal infections which are the main trigger for decompensation of cirrhosis and development of complications and thereby infection hugely impacts morbidity and mortality in these patients. However, there is no clinical test available that allows rapid, on-site decision making if a patient is likely to develop an infection. The purpose of this study is to measure cytokines interleukin (IL) 6, IL8, IL10 and TNFalpha in patients with liver cirrhosis over a long follow-up period and test whether these inflammatory markers are able to predict the occurrence of infection before it becomes clinically significant. For this purpose, one hundred fifty consecutive patients with diagnosis of liver cirrhosis will be followed bi-monthly for 18 months. Blood samples will be collected for the cytokine measurements and infection cases will be reported at each study visit.

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

18 years and older (ADULT, OLDER_ADULT)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Sampling Method

Non-Probability Sample

Study Population

150 patients with biopsy proven or clinically evident liver cirrhosis

Description

Inclusion Criteria:

  • Patients with clinical, radiological and/or histological evidence of liver cirrhosis
  • Age above 18 (inclusive) at the time of screening
  • Able and willing to give written informed consent and to comply with the requirements of the study

Exclusion Criteria:

  • Infection during the last 14 days before screening
  • Gastrointestinal bleeding within the last 14 days before screening
  • Antibiotic therapy at the time of screening (except prophylaxis of spontaneous bacterial peritonitis)
  • Shock or cardiac failure requiring inotrope treatment at the time of screening
  • Hepatic encephalopathy grade >2
  • Findings suggestive of organic nephropathy or a serum creatinine level of more than 2 mg/dl
  • Human immunodeficiency virus infection at time of inclusion
  • Use of immunomodulating agents within one month prior to screening (e.g. steroids)
  • Any disease (e.g., advanced neoplasia) that could affect the short-term prognosis
  • Any disease or condition which the investigator or treating physician feels would interfere with the trial or the safety of the subject

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
Liver Cirrhosis
Single cohort of patients with liver cirrhosis to be investigated in the study. Two-monthly measurements of serum cytokines.

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
Time Frame
Clinically significant infection requiring antibiotic, antiviral or antifungal treatment and hospitalisation.
Time Frame: 18 months
18 months

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.
Outcome Measure
Time Frame
Mortality
Time Frame: 18 months
18 months
All infections
Time Frame: 18 months
18 months
Hospitalisation for reasons other than infection
Time Frame: 18 months

Study record dates

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
March 1, 2009

Primary Completion (Actual)

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.
March 1, 2010

Study Completion (Actual)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
