Long Term Follow-up of Hepatitis C Cured Patients

Cirrhosis Clinical Trial

Official title: Predicting Outcomes in Hepatitis C Patients With Compensated Advanced Chronic Liver Disease Cured With New Antivirals

Status Completed

Clinical Trial Summary

Objectives:

The general objective of the present project is to gain a better understanding of disease outcome in cACLD patients treated with the new oral DAA. In particular, the project will focus on:

• To evaluate the long term prognosis of patients with compensated advanced chronic liver disease (cACLD) who achieve sustained virological response (SVR) after the new oral direct-acting antiviral agents (DAA), and determine clinical and elastographic basal and follow-up parameters to identify low and high risk groups of developing liver-related decompensation.

Methods:

Prospective cohort study in patients with cACLD in whom basal and annual clinical features and liver stiffness measurements (LSM) will be performed, and survival free of liver-related events will be analyzed.

Clinical Trial Description

HYPOTHESIS:

• The prognosis of cACLD patients who achieve SVR will improve during follow-up and this will be reflected in an improvement in liver and spleen stiffness and reduction of liver-related events. However, on an individual basis, because of many confounding factors, predictability is unknown.

OBJECTIVES:

The general objective of the present project is to gain a better understanding of disease outcome in cACLD patients treated with the new oral DAA. In particular, the project will focus on to determine simple clinical and elastographic basal and follow-up parameters to identify low and high risk groups for developing liver-related decompensation in cACLD patients who achieve SVR after DAA therapy. As a consequence of this, to provide guidance to clinicians to decide which cACLD patients should be indefinitely followed and which ones can be discharged from follow up, and also provide solid information to patients regarding the possible outcome of their cACLD after SVR.

• Study design: Prospective cohort study in an academic center to evaluate long term prognosis of patients with cACLD who achieve SVR after DAA therapy.

• Research subjects: All consecutive patients meeting inclusion criteria who have received DAA therapy from 1st January 2015 to 31st March 2016.

• Variables: Variables will be collected at baseline and annually for a period of 5 years. Basal data on genotype/subtype, interleukin 28B, viremia, type and duration of therapy. Data of liver function (INR, albumin, bilirubin), platelet count, aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (AP), gamma-glutamyltransferase (GGT), US findings (spleen size, collaterals), liver and spleen stiffness, body mass index (BMI), presence of metabolic syndrome factors (diabetes, dyslipemia, hypertension), alcohol and tabacco use, treatment with statins and development of liver-related events. The subgroup of patients with known esophageal varices prior to therapy will receive a second endoscopy 12-18 months after finishing therapy. Liver biopsies will be performed (after consent) at the end of follow-up (5 years) in the group of patients who will be candidates for being discharged (LSM<10 kPa) to ensure cirrhosis regression and learn about the correlation between LSM and histology after SVR.

• Data collection methods and analysis: Patients will be monitored at the outpatient clinics every 6 months as per usual clinical practice. Every 6 months, clinical data, laboratory tests and abdominal US will be obtained. Liver and spleen stiffness (Fibroscan, Echosens) will be performed annually after finishing treatment by an experienced member (MP), using usual quality criteria. Spleen stiffness measurements will be performed under US spleen localization and with the same device and conditions than liver stiffness. All data will be registered in a database. ;
