High Level of HIV-1 Drug Resistance Mutations Found in Adolescents with Detectable Viremia in Cameroon

Researchers at the University of Douala in Cameroon have identified a high level of HIV-1 drug resistance mutations among adolescents with detectable viremia. The study, published in the Journal of Antimicrobial Chemotherapy, analyzed 127 plasma and paired buffy-coat samples collected from 90 adolescents between February and September 2021. The findings suggest that about 80% of participants harbored drug resistance mutations to at least one drug class in circulating and archived viruses, with a significant proportion of resistance mutations detected in both viral populations.

Key Takeaways:

  • The study found a high level of HIV-1 drug resistance mutations among adolescents with detectable viremia, with about 80% of participants harboring DRMs to at least one drug class in circulating and archived viruses.
  • The majority of DRMs (61.9%) were found in recombinant CRF02_AG viruses, and about 56.7% of DRMs were detected in both circulating and archived viral populations.
  • The study suggests that a comprehensive profiling of DRMs in both viral populations would provide additional information for adolescents with detectable viremia.
  • The high level of resistance found in the study highlights the need for effective antiretroviral therapy and surveillance strategies to monitor and manage HIV-1 drug resistance in adolescents in Cameroon.
  • The study's findings have significant implications for public health policy and practice in Cameroon, where HIV/AIDS is a major public health concern.
  • The research was supported by Agence Nationale de Recherches sur le Sida et les hepatites virales and IRD.

Statistics:

  • 80.4% of participants harbored DRMs to at least one drug class in circulating viruses.
  • 77.3% of participants harbored DRMs to at least one drug class in archived viruses.
  • 56.7% of DRMs were detected in both circulating and archived viral populations.
  • 29.8% of DRMs were found exclusively in circulating strains, compared to 13.4% in archived viruses.
