AB Sixty-nine patients with chronic hepatitis C (CH-C) were treated with
interferon therapy, and serum collagen type IV (s-collagen IV) levels
were measured by enzyme immunoassay to analyze the responsiveness to
interferon therapy. Classified by the improved pattern of serum alanine
aminotransferase levels after interferon administration, 23 patients
were judged as sustained responders, 23 as transient responders, and 23
as non-responders. Fibrotic grades of the liver sample correlated
statistically with the levels of s-collagen IV (P < 0.01). Pre-therapy
s-collagen IV levels of sustained responders were significantly lower
than those of the other responders, and only sustained responders showed
a significant decrease of s-collagen IV levels after interferon therapy,
in accordance with histologic improvement. Multivariate analysis showed
that s-collagen IV and hepatitis C virus genotype were the most
important factors affecting the response to interferon therapy of all
variates. Thus, s-collagen IV is one of the most useful aids for the
evaluation of liver fibrotic grade in CH-C and a potent predicting
indicator for the responsiveness to interferon therapy.
