Close correlation between hepatitis C virus serology and polymerase chain reaction in chronically infected patients
1Institut für Medizinische Mikrobiologie und Immunologie, Hamburg, Germany.
Insights
Antibodies to hepatitis C virus (HCV) strongly correlate with the presence of HCV RNA in patients, indicating reliable viral detection. This finding is crucial for diagnosing and managing chronic hepatitis C.
Area of Science:
- Hepatology
- Virology
- Immunology
Background:
- Hepatitis C virus (HCV) infection is a major cause of chronic liver disease.
- Detecting persistent antibodies to recombinant HCV antigens is a common diagnostic approach.
- The correlation between antibody presence and active viral RNA requires further elucidation.
Purpose of the Study:
- To ascertain if the presence of anti-HCV antibodies correlates with detectable HCV RNA in serum.
- To evaluate the diagnostic utility of anti-HCV antibodies in patients with chronic hepatitis.
- To assess the reliability of antibody testing for identifying active HCV infection.
Main Methods:
- Polymerase chain reaction (PCR) was employed to detect HCV RNA in serum samples.
- 85 patients with confirmed anti-HCV positivity were analyzed.
- Liver biopsies from a subset of patients were also examined for HCV RNA.
Main Results:
- A high correlation (97.6%) was observed between anti-HCV antibody positivity and the detection of HCV RNA.
- HCV RNA was detected in 83 out of 85 (97.6%) anti-HCV positive patients.
- HCV-specific RNA was also identified in liver biopsies of positive patients.
Conclusions:
- Persistent anti-HCV antibodies are a strong indicator of the presence of HCV RNA.
- PCR detection of HCV RNA is highly reliable in anti-HCV positive individuals.
- The study validates the use of antibody testing in conjunction with RNA detection for HCV diagnosis.
Abstract:
To determine whether the persistent presence of antibodies to recombinant antigens of the hepatitis C virus (HCV) corresponds to the presence of hepatitis C virus RNA in the same serum, 85 anti-HCV positive patients were studied by the polymerase chain reaction (PCR). The focus of the research was on patients with chronic hepatitis. Eighty- three patients were found to be positive by PCR; only two were negative. In addition, liver biopsies taken from seven patients positive for anti-HCV were shown to contain HCV-specific RNA. Sera collected from three patients suspected to have NANB hepatitis on the basis of clinical symptoms were negative both for HCV antibodies and HCV RNA. The correlation between HCV antibody positivity and detection of HCV RNA was 97.6%.
