Chronic hepatitis alters serum transferrin isoforms. Trisialotransferrin levels may indicate disease progression and fibrosis stage in patients with chronic hepatitis.
Area of Science:
- Biochemistry
- Hepatology
- Clinical Chemistry
Background:
- Chronic hepatitis impacts liver function and serum protein profiles.
- Transferrin isoforms are glycosylated variants of transferrin, a key iron-binding protein.
Purpose of the Study:
- To investigate the alterations in serum transferrin isoform profiles in patients with chronic hepatitis.
- To determine if specific transferrin isoforms correlate with disease activity and fibrosis staging.
Main Methods:
- Serum samples from 160 chronic hepatitis patients were analyzed.
- Capillary electrophoresis using the MINICAP system was employed for isoform separation and quantification.
Main Results:
- Increased tetrasialotransferrin and decreased pentasialotransferrin levels were observed in chronic hepatitis patients.
- Trisialotransferrin levels showed significant differences based on portal/periportal activity, lobular activity, and fibrosis stage.
- No significant correlations were found between tetrasialotransferrin or pentasialotransferrin levels and disease progression or fibrosis stage.
Conclusions:
- Chronic hepatitis significantly affects the serum transferrin isoform profile.
- Trisialotransferrin emerges as a potential biomarker for assessing chronic hepatitis progression and fibrosis severity.

Metabolic Regulation:
The liver is the central organ involved in regulating blood composition. It stabilizes blood glucose levels, maintaining them within the range of 70–110 mg/dL. When these levels drop, the liver breaks down glycogen reserves and releases glucose into the bloodstream. It can...
