Comparaison of liver histology, morphometry and blood tests to assess fibrosis progression
101 pts with HCV±HIV Follow-up: 96 w Histology Blood tests * The area of fibrosis was the sole histological characteristic with a significant change (%). * CirrhoMeter was the only blood test with a significantly higher change than that of area of fibrosis (p=0.039). * CirrhoMeter Area of fibrosis Calès, J Viral Hepatitis 2012 * : significant change 20

23
Conclusion Considering non-invasive tests in HCV hepatitis, blood test and elastometry have the advantage to be independent methods. In case of discrepant results, two solutions: Another third examination like liver biopsy Or test combination For follow-up, certain blood test(s) could be more reproducible and more sensitive to detect small changes than other examinations.
