Screening of hepatitis D virus in blood donors in Dalian
Journal Title: Chinese Journal of Blood Transfusion - Year 2023, Vol 36, Issue 1
Abstract
Objective To investigate the prevalence of hepatitis D virus in Dalian blood donors. Methods The samples reactive to HBV in blood screening were selected with the following confirmed results: 1)HBsAg+ &HBV DNA+ ; 2)HBsAg+ & HBV DNA-; 3)HBsAg-&HBV DNA+ ; 4)NAT-yield uncertain. Qualified samples in routine blood screening were additionally tested with anti-HBc+ and anti-HBs+. All samples selected were tested HDV IgG further. Initial reactive samples would be tested by another HDV IgG assay and HDV IgM assay. HDV IgG positive was confirmed when samples were reactive to two HDV IgG assays. Results None HDV antibodies were detected among 1 344 unqualified samples (507 HBsAg+ &HBV DNA+, 33 HBsAg+ &HBV DNA-, 477 HBsAg-&HBV DNA+ and 327 NAT-yield uncertain samples) or 766 qualified samples (397 anti-HBc+ and 369 anti-HBs samples) in blood screening. Conclusion The prevalence of HDV infections among Dalian blood donors eligible in pre-donation screening seemed extremely low. However, for areas with high HBV prevalence, the risk of blood safety caused by OBI co-infection with HDV should not be ignored.
