Insights
Persistent GB virus C (GBV-C) co-infection with human immunodeficiency virus (HIV) does not significantly alter AIDS progression in Chinese former blood donors. This study found no association between GBV-C and HIV viral load or CD4+ T-cell counts.
Area of Science:
- Virology
- Immunology
- Epidemiology
Context:
- Conflicting reports exist on whether GBV-C co-infection affects HIV/AIDS progression.
- GBV-C co-infection with HIV is prevalent in certain populations.
- Understanding co-infection impact is crucial for managing HIV/AIDS.
Purpose:
- To investigate the association between GBV-C replication and HIV viral load and CD4+ T-cell counts in HIV-1 positive individuals.
- To determine if GBV-C co-infection influences the progression of AIDS in ART-naive patients.
Summary:
- A study of 203 HIV-1 positive former blood donors in China found 25.6% were co-infected with GBV-C.
- No significant association was observed between GBV-C infection and CD4+ T-cell counts or HIV viral loads.
- The findings suggest GBV-C co-infection does not significantly impact HIV/AIDS progression in this cohort.
Impact:
- Provides evidence against a significant role of GBV-C in modulating HIV/AIDS progression in a specific Chinese population.
- Highlights the need for further research to resolve conflicting findings on GBV-C and HIV co-infection.
- Informs clinical understanding and management strategies for HIV patients, particularly in regions with high GBV-C prevalence.
Abstract:
Several research groups have recently reported that persistent GB virus C (GBV-C) co-infected with human immunodeficiency virus (HIV) leads to slower AIDSs disease progression than HIV-1 infection alone. However, these findings were not confirmed by several other studies. To investigate the association between GBV-C replication and plasma HIV loads and CD4+ T cell counts, 203 HIV-1 positive former blood/plasma donors(FBDs) were enrolled from Fuyang city of Anhui Province in China. Plasma specimens were collected from them and were tested for GBV-C using RT-PCR and ELISA. Out of 203 specimens, 52 (25.6%) cases were positive for GBV-C, including 35 male (67.3%) and 17 female (32.7%) cases. No significant association was identified between GBV-C infection and CD4+ T-cell counts or between GBV-C infection and HIV viral loads. Since all the subjects studied were naive to ART, the influence of therapy on AIDS disease progression was ruled out in this study. Overall, our data indicated that HIV-1 positive male FBDs were prone to be infected, GBV-C coinfection with HIV-1 does not significantly influence HIV/AIDS disease progression during the late stage of chronic HIV-1 infection.
