SummaryThe hepatitis G virus (HGV) has recently been identified as a new member of the Flaviviridae family. Infection by this virus is thought to be associated with blood borne hepatitis. In this study, the presence of HCV- and HGV-RNAs in serum or plasma (175 patients) and in peripheral blood mononuclear cells (PBMC) (133 patients) was investigated in patients with clotting disorders using a sensitive reverse transcriptase polymerase chain reaction (RT-PCR). HGV-RNA was detected in serum of 26 patients (14.8%). In apparently healthy blood donors, serum HGV-RNA was detected in 4 of 358 individuals investigated (1.12%). Ninety two percent of the 26 serum HGV-RNA positive patients had coinfection with the hepatitis C virus (HGV), especially with HCV genotype lb, the most common genotype in Belgium. Of these coinfected patients, 15 (62.5%) showed elevated serum ALT levels. Two patients who were solely infected with HGV had normal serum ALT. HGV-RNA in PBMC was found in 18 patients, of whom 3 were negative for serum HGV-RNA. As in case of HCV, HGV-RNA in PBMC is preferentially sensitive to interferon treatment. Nevertheless, rapid reappearance of HGV-RNA in PBMC was observed after cessation of treatment. In one patient, persistent serum ALT elevation seems to be associated with continued HGV viremia, despite the disappearance of serum HCV-RNA.

Abstract Background: Studies indicate that in most patients with chronic hepatitis C, viral RNA is present not only in plasma but also in Peripheral Blood Mononuclear Cells (PBMC). Furthermore, the PBMC compartment may be a preferred site for HCV, which is able to reinitiate viral replication after HCV treatment, even if clearance occurred. The aim of this study was to detect the persistence of hepatitis C viral RNA in both serum and PBMCs at 12 and 24 weeks of treatment in chronic hepatitis C virus (CHC) patients with sofosbuvir based therapy. Methods: 75 CHC patients were tested for HCV- RNA in serum at 0, 12 & 24 weeks of treatment, and for HCV- RNA in PBMCs on the 12 & 24 weeks. Results: At week 12 of treatment all patients had no HCVRNA in their serum; however, 8 cases were positive for HCV RNA in their PBMC. After 24 weeks of treatment, HCV RNA was re-examined in both serum and PBMCs for all patients. Six out of the eight cases that were found having positive HCV RNA in their PBMCs turned positive HCV RNA in the serum. While the other two cases still negative for HCV RNA in the serum. Interestingly, another two cases out of the sixty-seven cases that were found having negative HCV RNA in their PBMC turned positive HCV RNA in the serum. Conclusions: Absence of HCV RNA in PBMC is a better predictor of good response after treatment of CHC patients with DAAs, than its absence in the serum.

In order to investigate hepatitis C virus (HCV) persistence and replication in peripheral blood mononuclear cells (PBMC) from a group of haemophilic individuals, HCV production and release to PBMC culture supernatants (SNs) from HCV singly infected patients and HIV/HCV co-infected patients was studied. HCV RNA+ SNs were found more frequently from HIV/HCV co-infected individuals (89·5 %) with poor reconstitution of their immune status than from singly HCV-infected patients (57 %) or from HIV/HCV co-infected individuals with a good response to highly active anti-retroviral therapy (50 %). The presence of the HCV genome in culture SNs was associated with lower CD4+ T-cell counts and with a more severe clinical picture of HIV infection. In spite of prolonged negative HCV viraemia, PBMC from HIV/HCV co-infected patients released the HCV genome after culture. HCV permissive PBMC allowed generation of HCV productive B cell lines with continuous HCV replication. These findings add further weight to the involvement of PBMCs in persistence of HCV infection and emphasize the role of B lymphocytes as HCV reservoirs.
