Abstract |
Objectives |
To date, no study has been done yet on the distribution of Hepatitis C virus genotypes in Lubumbashi, Democratic Republic of Congo. The objective of this work was to determine the seroprevalence and study the distribution of hepatitis C virus (HCV) genotypes among blood donors in Lubumbashi, DRC.
Methods |
This was a cross-sectional descriptive study among blood donors. The detection of anti-HCV antibodies was carried out by rapid diagnostic test (RDT) then confirmed by Chemiluminescent immuno-assay (CLIA). Viral load was determined by Nucleic Acid Amplification test (NAT) on Panther system and genotyping by Next Generation Sequencing (NGS) on Sentosa platform.
Results |
The obtained seroprevalence was 4.8%. Genotypes 3a (5.0%), 4 (90.0%) and 7 (5.0%) and a few drug resistance mutations were identified in the study population. Significant disturbances of some studied biochemical parameters (HDL-cholesterol, direct bilirubin, transaminases, ALP, GGT and albumin) have been observed in positive HCV blood donors. Irregular family and volunteer donors have been found as the socio-demographic characteristics associated with hepatitis C.
Conclusion |
With a seroprevalence of 4.8% obtained among blood donors, Lubumbashi is in an area with medium endemicity for HCV, highlighting the need to implement strategies aiming to improve transfusion safety among blood recipients in Lubumbashi. This study reports for the first time the presence of HCV strains of genotypes 3a, 4 and 7. These results might allow better therapeutic management of HCV infections and contribute to the development of the mapping of HCV genotypes in Lubumbashi and DRC as well.
