Trial summary

Chronic viral hepatitis often leads to liver scarring - cirrhosis. If the virus is eradicated from the liver, the liver scarring and liver function often recovers. In some patients the damage is too severe and recovery does not take place. Read more about this study

About this study

Official title: Changes in Dynamic Liver Function Tests in Patients With Chronic Viral Hepatitis Undergoing Antiviral Therapy

Chronic viral hepatitis often leads to liver scarring - cirrhosis. If the virus is eradicated from the liver, the liver scarring and liver function often recovers. In some patients the damage is too severe and recovery does not take place. It is not yet known which patients have liver disease that is too advanced to benefit from therapy nor is it known how fast the recovery occurs.

Non-intrusive dynamic liver testing (DLT) may allow us to predict the functionality of the liver post treatment and may guide us in treatment choices - for example patients who are predicted not to recover may be prioritised for transplantation. Indocyanine green (ICG) is a dye solely excreted by the liver into bile and used to measure its dynamic function. Transient elastography is similar to ultrasound and measures the degree of fibrosis within the liver.

The investigators hypothesise that the use of non-intrusive dynamic liver testing pre-treatment, will allow us to delineate patients before therapy who will have functional liver recovery following viral eradication.

The investigators hypothesise that monitoring changes in liver fibrosis and liver function in patients with historical viral clearance will allow an assessment of the likely speed of recovery of liver fibrosis and function - for example if all patients 5 years after treatment for viral hepatitis induced cirrhosis have 'normal' fibrosis and liver function scores the investigators will be able to conclude that recovery is complete within 5 years.

The investigators will perform a study pre and post-treatment assessing liver function using non-intrusive dynamic liver testing in addition to currently-used 'liver function' scoring systems, in a multivariate analysis, to determine whether or not the investigators can identify patients who are will have functional liver recovery post therapy.

Read the detailed description

Multiple diseases affect the liver's performance, including hepatitis' B and C viruses. Hepatitis infects the liver; ultimately leading to cirrhosis associated with complications (e.g. bleeding and death), termed decompensated cirrhosis. Hepatitis induced decompensated liver disease is likely to improve upon eradication of the virus as will liver function.

Recently, Hepatitis C has seen new, more efficacious therapies, allowing functional outcomes to be evaluated following viral clearance. It has been shown this treatment regime is effective in eliminating the virus in 70% of patients but functional improvement to be 40% with the rest stagnating or becoming worse. These patients may have benefited from liver transplantation initially, followed by viral eradication therapy.

Treatment of the Hepatitis B virus is to stop more copies to be produced within cells. This on the most part is successful and the liver recovers. However, after 5 years of treatment 26% of people do not recover sufficiently and the ability to identify these early is important to their future management.

Non-intrusive dynamic liver testing (DLT) may allow us to predict the functionality of the liver post treatment and may guide us in adequate management strategies. Indocyanine green (ICG) is a dye solely excreted by the liver into bile and used to measure its dynamic function. Transient elastography is similar to ultrasound and measures the degree of fibrosis within the liver.

The investigators hypothesise the use of non-intrusive dynamic liver testing pre-treatment, will allow us to delineate patients early, who would benefit from the most intensive treatments (e.g. transplant), and spare those with less severe disease the risks and potential side effects.

The investigators will perform a study pre and post-treatment for DLT. These will be amalgamated with currently-used scoring systems, in a multivariate analysis, to ascertain the values and thus best-treatment option for patients.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Transient elastographyDevice

    Also called Fibroscan

    Transient elastography will be measured using a Fibroscan® machine which is manufactured by echosens®. It has a CE mark of 0459.

    It is a non-invasive method to accurately measure stiffness of a patient's liver without the need for a liver biopsy. This is measured by an externally placed ultrasound probe which creates an elastic shear wave at 50Hz, and measures the velocity of the echo through the liver tissue. The liver stiffness is measured in kilopascals (kPa). It has been shown to be 99% effective in detecting cirrhosis in hepatitis C and has been shown to correlate with hepatoma production in both hepatitis C and hepatitis B. Values range from - normal < 9.6 kPa, significant fibrosis 9.6-11.4kPa, cirrhosis >11.5kPa. It cannot be used in patients with ascites.

  • Indocyanine Green excretionDevice

    Also called Pulsion Limon system

    The machine to monitor the elimination of Indocyanine green is manufactured by PULSION medical systems (Munich, Germany) and consists of the PulsioFlex monitor and LiMON module. The LiMON module is a finger probe which measure near-infrared wavelengths between 805nm and 905nm. The absorption maximum for Indocyanine green is 800nm and emission at 830nm. This is then used to produce two calculations. The first is plasma disappearance rate of indocyanine green (PDRICG). This is based on working out the constant and backward extrapolation and expressed as a percentage per minute. The other is the retention ratio after 15 minutes (ICG15).

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change from baseline following 1 year of treatment for chronic viral hepatitis with cirrhosis using transient elastography.

    Patients are treated for hepatitis B or hepatitis C and tested at baseline, 4 months and 1 year. Scores range from 0 to 75kPa with cirrhosis defined as above 11.5kPa. Change in baseline is noted. (Change = 4 month or 1 year measurement - baseline).

    Measured: Baseline, 4 months and 1 year

  2. Change from baseline following 1 year of treatment for chronic viral hepatitis with cirrhosis using indocyanine green excretion test using plasma disappearance rate.

    Patients are treated for hepatitis B or hepatitis C and tested at baseline, 4 months and 1 year. Measurement of plasma disappearance rate of Indocyanine green (PDRicg) is measured with normal between 18-25%/min. Change in baseline is noted.

    Measured: Baseline, 4 months and 1 year

  3. Change from baseline following 1 year of treatment for chronic viral hepatitis with cirrhosis using indocyanine green excretion test using plasma retention rate at 15 minutes.

    Patients are treated for hepatitis B or hepatitis C and tested at baseline, 4 months and 1 year. Measurement of retention rate of indocyanine green at 15 minutes is measured (ICG15) with normal being below 10%. Change in baseline is noted.

    Measured: Baseline, 4 months and 1 year

Secondary outcomes (1)
  1. Percentage of participants achieving normal fibroscan and or indocyanine green excretion test results at 3 or 5 years post initiation of treatment for viral hepatitis.

    Patients treated for hepatitis B or hepatitis C with cirrhosis are tested at either 3 or 5 years after initiation of treatment. Fibroscan, score (range from 0 to 75kPa with cirrhosis defined as above 11.5kPa), measurement of plasma disappearance rate of Indocyanine green (PDRicg) (normal between 18-25%/min) and measurement of retention rate of indocyanine green at 15 minutes is measured (ICG15) (normal below 10%) are tested with the percentage of patients achieving normal in all tests reported.

    Measured: 3 years, 5 years
