Insights
Hepatitis C virus (HCV) RNA detection is more accurately reflected by anti-HCV IgM antibody testing than by anti-HCV antibody testing. This simpler method is suitable for widespread use and can reduce post-transfusion hepatitis C.
Area of Science:
- Virology
- Immunology
- Hepatology
Context:
- Hepatitis C virus (HCV) infection is a significant global health concern.
- Accurate and accessible diagnostic markers for HCV are crucial for patient management and public health.
- Current diagnostic methods include detection of antibodies (anti-HCV, anti-HCV IgM) and viral RNA (HCV-RNA).
Purpose:
- To investigate the relationship and diagnostic agreement among different serum markers for Hepatitis C virus (HCV) infection.
- To evaluate the utility of anti-HCV IgM as a superior marker for detecting HCV viremia compared to anti-HCV.
- To assess the feasibility of anti-HCV IgM testing in basic healthcare settings.
Summary:
- Serum samples from various populations were tested for anti-HCV, anti-HCV IgM, and HCV-RNA using ELISA and RT-PCR.
- Anti-HCV IgM showed higher agreement rates with HCV-RNA across all groups compared to anti-HCV.
- Anti-HCV IgM testing is simpler, requires less specialized equipment than RT-PCR, and is effective in identifying active HCV infection.
Impact:
- Anti-HCV IgM testing is a more sensitive indicator of HCV viremia than anti-HCV.
- The ease of implementation makes anti-HCV IgM testing suitable for basic healthcare units.
- Widespread adoption of anti-HCV IgM testing could significantly reduce the incidence of post-transfusion hepatitis C.
Abstract:
We tested anti-HCV, anti-HCV IgM and HCV-RNA in serum samples from general adults, blood donors, acute hepatitis patients and liver cirrhosis patients by the methods of ELISA and RT-PCR so as to study the relationship among serum markers. Results showed that the detected positive rates of anti-HCV are 3.57%, 8.58%, 6.25% and 48.38% in normal adults, blood donors, acute hepatitis patients and liver cirrhosis patients respectively; agreement rates between anti-HCV and HCV RNA are 11.43%, 61.11%, 80.0%, and 73.33% in the four groups of people above; agreement rates between anti-HCV IgM and HCV RNA are 75.0%, 90.9% 81.81% and 100% in the same groups of people. Authors pointed out that anti-HCV IgM is superior to anti-HCV in the aspect of revealing HCV viremia. In comparison with RT-PCR, testing anti-HCV IgM is easier and does not need special instruments, so it is suitable to develop in the basic hygiene units. Testing anti-HCV IgM instead of anti-HCV, the morbidity of post-transfusion hepatitis C can be decreased further.
