Interplay between HIV and Human Pegivirus (HPgV) Load in Co-Infected Patients: Insights from Prevalence and Genotype Analysis. Viruses 2023; 16:5. [PMID: 38275941 PMCID: PMC10820514 DOI: 10.3390/v16010005] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/30/2023] [Revised: 12/14/2023] [Accepted: 12/15/2023] [Indexed: 01/27/2024] Open
Abstract
Human pegivirus (HPgV) is transmitted through sexual or parenteral exposure and is common among patients receiving blood products. HPgV is associated with lower levels of human immunodeficiency virus (HIV) RNA and better survival among HIV-infected patients. This study aimed to investigate the prevalence of HPgV and determine its subtypes in HIV-infected individuals living in Istanbul, which has the highest rate of HIV infection in Türkiye. Total RNA extraction from plasma, cDNA synthesis, and nested PCR were performed for HPgV on plasma samples taken from 351 HIV-1-infected patients. The HPgV viral load was quantified on HPgV-positive samples. HPgV genotyping was performed by sequencing the corresponding amplicons. In the present study, the overall prevalence of HPgV RNA in HIV-infected patients was 27.3%. HPgV subtypes 1, 2a, and 2b were found, with subtype 2a being the most frequent (91.6%). Statistical analysis of HIV-1 viral load on HPgV viral load showed an opposing correlation between HIV-1 and HPgV loads. In conclusion, these data show that HPgV infection is common among HIV-positive individuals in Istanbul, Türkiye. Further comprehensive studies are needed to clarify both the cellular and molecular pathways of these two infections and to provide more information on the effect of HPgV on the course of the disease in HIV-infected individuals.

Hepatitis C and Human Pegivirus Coinfection in Patients with Chronic Hepatitis C from the Brazilian Amazon Region: Prevalence, Genotypes and Clinical Data. Viruses 2023; 15:1892. [PMID: 37766298 PMCID: PMC10536978 DOI: 10.3390/v15091892] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/20/2023] [Revised: 08/08/2023] [Accepted: 08/20/2023] [Indexed: 09/29/2023] Open
Abstract
Coinfection of HPgV-1 with hepatitis C virus (HCV) is common due to shared modes of transmission, with a prevalence of HPgV-1 viremia of approximately 20% among individuals with chronic HCV infection. The aim of the present study was to estimate the prevalence of HPgV-1 RNA and circulating genotypes in patients with hepatitis C from a health service located in the city of Belém, in the state of Pará, Northern Brazil. A total of 147 samples were included in the study from February to December 2019. Among the participants, 72.1% (106/147) were monoinfected with HCV, with detectable HCV viral RNA, and 27.9% (41/147) were coinfected with HCV/HPgV-1. The most frequently found genotypes were HPgV-1 genotypes 1 and 2 (36.6% and 63.4%), respectively. While for HCV there was a predominance of genotypes 1 and 3 (58.5% and 41.5%). No significant differences were found when comparing any risk, sociodemographic, or clinical factors between groups. Also, there was no statistically significant difference when relating the viral genotypes of both agents. This study indicated that the prevalence of infection by HPgV-1 is high in HCV carriers in Belém, Pará, and probably does not change the clinical course of HCV infection, however, further studies are still needed.

Abstract
Human pegivirus (HPgV-1), previously known as GB virus C (GBV-C) or hepatitis G virus (HGV), is a single-stranded positive RNA virus belonging to the genus Pegivirus of the Flaviviridae family. It is transmitted by percutaneous injuries (PIs), contaminated blood and/or blood products, sexual contact, and vertical mother-to-child transmission. It is widely prevalent in general population, especially in high-risk groups. HPgV-1 viremia is typically cleared within the first 1–2 years of infection in most healthy individuals, but may persist for longer periods of time in immunocompromised individuals and/or those co-infected by other viruses. A large body of evidences indicate that HPgV-1 persistent infection has a beneficial clinical effect on many infectious diseases, such as acquired immunodeficiency syndrome (AIDS) and hepatitis C. The beneficial effects seem to be related to a significant reduction of immune activation, and/or the inhabitation of co-infected viruses (e.g. HIV-1). HPgV-1 has a broad cellular tropism for lymphoid and myeloid cells, and preferentially replicates in bone marrow and spleen without cytopathic effect, implying a therapeutic potential. The paper aims to summarize the natural history, prevalence and distribution characteristics, and pathogenesis of HPgV-1, and discuss its association with other human viral diseases, and potential use in therapy as a biovaccine or viral vector.

[PMID: 34601095 DOI: 10.1016/j.meegid.2021.105099] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/08/2021] [Revised: 09/20/2021] [Accepted: 09/27/2021] [Indexed: 12/24/2022]
Abstract
Human pegivirus type 1 (HPgV-1) is a non-pathogenic RNA virus in the Flaviviridae family that usually occurs as a co-infection with hepatitis B virus (HBV) or hepatitis C virus (HCV), though some evidence suggests it may play a role in certain cancers. The present study aimed to determine the prevalence of HPgV-1 infection in Iraqi anti-HCV IgG-positive patients, the risk factors associated with this infection, and the genotype of local isolates of this virus. A total of 88 anti-HCV IgG-positive patients participated in this cross-sectional study. Viral RAN was extracted from whole blood samples, and cDNA was produced using reverse transcriptase-polymerase chain reaction (RT-PCR). Two pairs of primers were used in nested PCR to amplify the virus genome's 5'-untranslated region (5'UTR). For direct sequencing, fourteen PCR products from the second round of PCR were chosen at random. A homology search was performed using the basic local alignment search tool (BLAST) program to identify the resultant sequencing. The phylogenetic tree of the local isolates and 31 reference isolates was constructed using MEGA X software to estimate the virus's genetic diversity and relatedness. Out of 88 patients included in this study, 27(30.68%) of patients were found to be positive for HPgV-1 RNA. The nucleotide homology between the 14 local isolates and the reference isolates. was found to be 87-97%. Phylogenetic analysis results in a tree with four main parts, which are distributed as follows: 10 local isolates are genotype 2; 2 are genotype 1; 1 is genotype 5, and 1 is genotype 6. We conclude that when compared to other countries, the infection rate of Iraqi anti-HCV IgG-positive patients with HPgV-1 is relatively high (30.68%). The most common HPgV-1 genotype in Iraq is genotype 2.
