    Abstract:
    We have recently described a fibrosis index combining serum procollagen type III N-terminal peptide (PIIINP) and matrix metalloproteinase 1 (MMP-1) concentrations for evaluating the amount of liver fibrosis in chronic hepatitis C patients. The aims of the present study were to validate this score in another cohort of patients and to assess its variations along those of TIMP-1, hyaluronic acid (HA) and MMP-9 during antiviral treatment. Seventy-nine patients treated by interferon-alpha and ribavirin for 24 or 48 weeks were included. A liver biopsy was performed within the 6 months before the start of treatment. Serum markers were measured in serum collected the day of the liver biopsy, at start of treatment, and every 3 months during treatment and a 6-month follow-up period. The PIIINP/MMP-1 index was significantly correlated to the METAVIR fibrosis (r = 0.68, P < 0.001). Its overall diagnostic value defined by the area under the receiver operating characteristics curves was 0.77 for discriminating F1 vs F2F3F4, and 0.81 for discriminating F1F2 vs F3F4, and was better than that observed for HA and TIMP-1. At the end of follow-up, the PIIINP/MMP-1 index significantly decreased in responders and remained stable in nonresponder patients. This decrease occurred early and continued regularly during the treatment period. This variation was because of both a decrease of PIIINP and an increase of MMP-1 concentrations. HA and TIMP-1 serum concentrations were also significantly lower at the end of follow-up in responder patients, but early changes were minimal and not influenced by the response to treatment. Our study shows that a noninvasive index combining PIIINP and MMP-1 is a useful tool to follow-up fibrosis change during and after antiviral therapy chronic hepatitis C patients.
