Abstract
UNLABELLED
Chronic hepatitis develops in at least half of persons acutely infected with hepatitis C virus (HCV). Ten to 25% of these patients will develop cirrhosis. Serum procollagen-III peptide (PIIIP) may be of value in predicting the development of chronic active fibrogenic liver disease. It has been reported that in chronic viral C hepatitis, the levels of hepatitis C virus-RNA (HCV-RNA) correlate directly with the severity of hepatic histology and inversely with response to interferon therapy.
OBJECTIVES
The aims of this study were to correlate the level of PIIIP with HCV-RNA concentrations, ALT values, and histological severity in patients with chronic viral C hepatitis.
METHODS
Eighty-six patients with chronic C hepatitis were divided into three groups: group I (n = 34), mild chronic active hepatitis, group II (n = 25), moderate to severe chronic active hepatitis, and group III (n = 27), cirrhosis. HCV-RNA was measured by Quantiplex, and PIIIP was measured by radioimmunoassay-gnostic assay.
RESULTS
Mean +/- SD level of ALT in group I was 114 +/- 48 U/L, group II was 169 +/- 115 U/L, and group III was 160 +/- 94 U/L. The mean +/- SD level of HCV-RNA in group I was 110 +/- 130 x 10(5) Eq/ml, in group II was 140 +/- 140 x 10(5) Eq/ml, and in group III was 70 +/- 80 x 105 Eq/ml. The mean +/- SD level of PIIIP in group I was 0.6 +/- 0.2 U/ml, in group II was 0.9 +/- 0.4 U/ml, and in group III was 1.2 +/- 0.6. There was a significant difference in the levels of PIIIP among the three groups (p = 0.0001). There was no correlation among ALT, HCV-RNA, and PIIIP in any of the three groups.
CONCLUSIONS
PIIIP peptide determinations in patients with chronic viral C hepatitis are reflective of histological severity and may provide relatively noninvasive means of following disease progression.
