Impact of Blood Transfusion on the Prevalence of HHpgV-1, HPgV-1, and B19V Among Iranian HCV-infected Patients With Hemophilia.

ABSTRACT

OBJECTIVE: Blood-derived products from patient with hemophilia treated by factor VIII concentrates are potential sources of transfusion-transmitted infections, including human immunodeficiency virus, hepatitis, human pegivirus-1 (HPgV-1), B19 virus, and also human hepegivirus-1 (HHpgV-1). In the current study, we investigated the impact of blood transfusion on the prevalence of HHpgV-1, HPgV-1, and B19 virus in plasma of Iranian patient with hemophilia after direct-acting antiviral treatment of hepatitis C virus (HCV) infections for the first time. MATERIALS AND METHODS: A total of 170 patients with hemophilia who received direct-acting antivirals were enrolled in this study. Among them, 92 patients had a history of blood transfusion. The presence of HHpgV-1, HPgV-1, and B19 virus was detected by nested polymerase chain reaction analysis using the conserved primers. The plasmids harboring 5'-UTR and NS3 were used as positive controls for HPgV-1 and HHpgV-1, respectively. RESULTS: Our data identified 3 individuals with HHpgV-1 viremia (1.76%), 11 individuals with HPgV-1 viremia (6.47%), and 33 individuals with B19 viremia (19.4%). All patients were negative for hepatitis B virus, human immunodeficiency virus, and HCV infections. These findings indicated lower transmissibility or higher rates of virus clearance for HHpgV-1, HPgV-1, and B19 virus as compared with other bloodborne human flaviviruses such as HCV. However, the prevalence of B19 virus was significantly higher than the other 2 viruses. CONCLUSION: In general, these findings showed that the history of blood transfusion could increase the risk of viral transmission of bloodborne viruses among patient with hemophilia.
