Correlation of Antithrombin Functional Status and Levels with Liver Fibrosis in Patients with Hepatitis C
Insights
Antithrombin (AT) levels are normal in early liver fibrosis but decrease significantly in advanced stages of chronic liver disease with hepatitis C. This indicates fibrosis severity impacts AT status.
Area of Science:
- Hepatology
- Hematology
- Clinical Biochemistry
Background:
- Coagulation factor abnormalities are linked to liver disease.
- Antithrombin (AT) is a key coagulation inhibitor.
- Chronic liver disease, particularly hepatitis C, affects hemostasis.
Purpose of the Study:
- To assess antithrombin (AT) activity and levels in hepatitis C patients.
- To correlate AT status with liver fibrosis severity.
- To understand the role of AT in chronic liver disease progression.
Main Methods:
- Enrolled 75 patients with chronic liver disease and hepatitis C.
- Measured AT activity and quantitative AT levels using specific reagent kits.
- Assessed liver fibrosis severity through histological grading of liver biopsies.
Main Results:
- 30 out of 75 patients exhibited reduced AT activity.
- Quantitative assays revealed decreased AT levels in 30 patients.
- Early fibrosis stages showed normal or minimally affected AT, while advanced stages had markedly reduced AT.
Conclusions:
- Liver fibrosis severity significantly impacts antithrombin (AT) levels and activity.
- Reduced AT is associated with advanced stages of liver fibrosis in hepatitis C.
- AT status serves as a potential indicator of liver disease progression.
Background:
Abnormal levels of coagulation factors and their inhibitors have shown association with liver diseases. The objective of this study was to determine the qualitative and quantitive status of antithrombin (AT) in patients with chronic liver disease associated hepatitis C infection and their correlation with severity of liver fibrosis.
Methods:
In this study, 75 (43 male and 32 female) known patients with chronic liver disease associated hepatitis C infection were enrolled. AT activity and quantitative immunoassays were carried out using Stachrom AT reagent kit (Diagnostica Stago, France) and Liatest AT reagent (Diagnostica Stago, France), respectively. Hepatic biopsies were obtained and graded for liver fibrosis from all study participants.
Results:
Of the 75 patients, 45 had normal AT while 30 showed lower activity of AT. Similarly, the quantitative assay showed reduced levels of AT in 30 patients and normal levels in 45 patients.
Conclusions:
In the early stages of liver fibrosis, AT activity and antigenic levels were found to be normal or minimally affected. While advanced stages of the disease showed markedly reduced levels of AT and activity. Hence, it can be concluded that the degree of fibrosis affects the status of AT.
