Insights
This study investigated viral markers in blood donors and high-risk individuals. Hepatitis C virus antibodies were frequently detected in specific patient groups and drug addicts, with regional variations observed.
Area of Science:
- Virology
- Infectious Diseases
- Public Health
Background:
- Blood and plasma donors, along with individuals at high risk for infections, are routinely screened for viral pathogens.
- Previous studies have indicated varying prevalence rates of viral infections across different populations and geographical regions.
Purpose of the Study:
- To determine the prevalence of antibodies to Human Immunodeficiency Virus types 1 and 2 (HIV-1/2), Human T-Lymphotropic Virus type 1 (HTLV-1), and markers for Hepatitis B Virus (HBV) and Hepatitis C Virus (HCV).
- To assess the detection rates in blood/plasma donors and individuals with high-risk exposure.
- To compare the performance of two commercial test systems for anti-HCV detection.
Main Methods:
- Serological testing for antibodies to HIV-1/2, HTLV-1, HBV markers, and anti-HCV.
- Analysis of detection rates in various donor groups (general, reserve) and high-risk populations (hematological patients, hemodialysis patients, drug addicts, medical personnel).
- Regional prevalence data collection for anti-HCV.
- Comparative evaluation of sensitivity and specificity for two commercial anti-HCV test systems (Ortho, USA and Organon, Holland).
Main Results:
- A high prevalence of anti-HCV was found in donors with elevated serum enzymes, hematological patients, hemodialysis patients, and drug addicts.
- Significant detection rates of HBV markers were observed in hematological patients and medical personnel in hematological and surgical clinics.
- Approximately 45% of reserve donors showed at least one HBV marker.
- Regional anti-HCV detection rates varied: 1-3% in Baltic countries, 2-5% in Russia, 5-7% in Middle Asia, and 8-12% in Moldova.
- The sensitivity and specificity of the Ortho and Organon anti-HCV test systems were comparable.
Conclusions:
- Hepatitis C virus poses a significant detection challenge in specific high-risk populations and certain geographical regions.
- Hepatitis B virus markers are prevalent among hematological patients and healthcare workers, necessitating continued vigilance.
- The evaluated commercial test systems demonstrate reliable performance for anti-HCV detection.
Abstract:
The rate of the detection of the antibodies to HIV-1/2, HTLV-1, the markers of hepatitis B and C viruses and cytomegaloviruses in blood and plasma donors and persons with high risk of the infections was studied. A high percentage of the detection of the antibodies to hepatitis C virus (anti-HCV) was observed in the donors with increased levels of the serum enzymes, hematological patients, hemodialysis patients and drug addicts. A high rate of the indication of the HB virus markers was also observed in hematological patients and medical personnel of hematological and surgical clinics. At least 1 marker of HB virus was shown to be detected per 45 per cent of the reserve donors. The rate of the detection of anti-HCV in the donors of various regions ranged within 1-3 per cent in the Baltic countries, 2-5 per cent in Russia, 5-7 per cent in the Middle Asia and 8-12 per cent in Moldova. The data on the sensitivity and specificity of two commercial test systems for the detection of the antibodies to hepatitis C virus (Ortho, USA and Organon, Holland) were comparable.
