Change of Glucose Metabolism and Fibrosis Markers in Patients With Hepatitis C Under Treatment With Antiviral Agents

July 20, 2020 updated by: Georg Dultz, Johann Wolfgang Goethe University Hospital

Examination of Changes of Parameters of Glucose Metabolism and Liver Fibrosis Stadium by Acoustic Radiation Force Impulse-Imaging and Transient Elastography in Patients With Chronic Hepatitis C Under Antiviral Treatment

Chronic hepatitis C infection is associated with changes of glucose metabolism end increased frequency of impaired glucose tolerance. This might be a additional risk factor for disease and fibrosis progression. The study aims to evaluate whether a therapy with direct-acting antiviral agents leading to a sustained virologic response directly impacts parameters reflecting glucose metabolism and fibrosis.

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.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Chronic hepatitis C infection is associated with changes of glucose metabolism end increased frequency of impaired glucose tolerance. It is well known that metabolic factors play an important role in fibrosis progression and steatohepatitis for example in non-alcoholic steatohepatitis (NASH). Accordingly changes in glucose metabolism in patients with chronic hepatitis C might directly impact disease and fibrosis progression. The study aims to evaluate whether a therapy with direct-acting antiviral agents leading to a sustained virologic response directly impacts parameters reflecting glucose metabolism and fibrosis. Follow-up examinations will determine the long-term metabolic changes of successful elimination of the virus by antiviral treatment.

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.

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.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Chronic hepatitis C under antiviral treatment with DAA
Patients with chronic hepatitis C infection and planned DAA treatment are enrolled prospectively. Parameters of glucose metabolism and liver fibrosis are measured at baseline, during therapy and up to one year after end of treatment.
Diagnostic test: Lab tests, non-invasive fibrosis (Fibroscan/ARFI)
Patient characteristics, lab values reflecting glucose metabolism and non-invasive fibrosis tests are documented at baseline, during therapy and up to one year after end of treatment.

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
Rate of patients with changes in glucose metabolism measured by fasting glucose
Time Frame: From baseline up to one year after end of treatment
rate of patients with normal fasting glucose (<100mg/dl), prediabetes (glucose 100-125mg/d) and diabetes (>126mg/dl)
From baseline up to one year after end of treatment
Rate of patients with changes in glucose metabolism measured by Homeostasis Model Assessment-index (HOMA)
Time Frame: From baseline up to one year after end of treatment

Homeostasis Model Assessment-index (HOMA) measures insulin resistance:

  1. <2,0 insulin resistance unlikely
  2. 2,0 - 2,5 insulin resistance possible
  3. 2,5 - 5,0 insulin resitance likely
  4. >5,0 proven insulin resitance
From baseline up to one year after end of treatment
Rate of patients with changes in glucose metabolism measured by HbA1c
Time Frame: From baseline up to one year after end of treatment
rate of patients with normal HbA1c (>6% Hb), prediabetes (6-6.4% Hb) and diabetes (>6.5% Hb)
From baseline up to one year after end of treatment

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
Measure Description
Time Frame
Liver fibrosis 1
Time Frame: From baseline up to one year after end of treatment
Evaluation of changes of parameters reflecting liver fibrosis: Fibroscan
From baseline up to one year after end of treatment
Liver fibrosis 2
Time Frame: From baseline up to one year after end of treatment
Evaluation of changes of parameters reflecting liver fibrosis: ARFI
From baseline up to one year after end of treatment
