[The diagnostic value of the detection of hepatic fibrosis serum markers in chronic viral hepatitis].

The diagnostic significance of serum markers of fibrosis was investigated in 92 patients with chronic viral hepatitis (CVH) by studying the collagenolythic activity of blood, proteasic inhibitor activity, collagen metabolism products (oxyproline fraction), and fibronectin. At the same time, the patients underwent puncture biopsy of the liver, which made it possible to determine the degree of process activity and the stage of its chronization. As the degree of fibrosis grew, the collagenase serum activity increased significantly, while the alpha1-proteinase inhibitor activity fell, the content of oxyproline (its fractions) increased, and the fibronectin level decreased. Hence, the measurement of the noted parameters allows for noninvasive diagnostics of CVH stages.
