Abstract Contemporary ART as Dolutegravir (DTG) has significantly advanced antiretroviral therapy, but relatively few data are available on its impact on the emergence of HIV-1 drug resistance mutations (DRMs). Monitoring the emergence of INSTI-associated DRMs following the introduction of DTG in Suriname will provide general insight and guide national HIV treatment strategies. All people living with HIV (PLHIV) in Suriname, for whom an INSTI drug resistance test was requested between September 2019 and February 2024 (n = 20), were included. HIV-1 integrase gene sequences were determined using Sanger sequencing. INSTI-associated mutations were identified using the Stanford HIV Drug Resistance Database program. The majority of the participants (66.7%) harbored HIV-1 subtype B, and 33.3% were B-recombinant forms. In addition to the INSTI wildtype, a strain was revealed carrying E157EQ and one person harbored a highly INSTI-resistant strain (E138K, G140S, Q148H and N155H). The emergence of a highly INSTI-resistant HIV-1 strain in Suriname, with unusual mutations for ART-experienced PLHIV exposed to DTG as the only INSTI, accentuates the need for continuous monitoring of the emergence of INSTI drug resistance mutations, not only to enable timely interventions and optimized treatment outcomes for PLHIV, but also to steer the decision making for ART protocols, especially for second generation INSTIs.

Mutation Information
Note
Basic Characteristics of Mutations
  • Mutation Site: The specific location in a gene or protein sequence where a change occurs.
  • Mutation Level: The level at which a mutation occurs, including the nucleotide or amino acid level.
  • Mutation Type: The nature of the mutation, such as missense mutation, nonsense mutation, synonymous mutation, etc.
  • Gene/Protein/Region: Refers to the specific region of the virus where the mutation occurs. Including viral genes, viral proteins, or a specific viral genome region. If the article does not specifically indicate the relationship between the mutation and its correspondence, the main
  • Gene/Protein/Region studied in the article is marked.
  • Genotype/Subtype: Refers to the viral genotype or subtype where the mutation occurs. If the article does not specifically indicate the relationship between the mutation and its correspondence, the main Genotype/Subtype studied in the article is marked.
  • Viral Reference: Refers to the standard virus strain used to compare and analyze viral sequences.
Functional Impact and Mechanisms
  • Disease: An abnormal physiological state with specific symptoms and signs caused by viral infection.
  • Immune: The article focuses on the study of mutations and immune.
  • Target Gene: Host genes that viral mutations may affect.
Clinical and Epidemiological Correlations
  • Clinical Information: The study is a clinical or epidemiological study and provides basic information about the population.
  • Treatment: The study mentioned a certain treatment method, such as drug resistance caused by mutations. If the study does not specifically indicate the relationship between mutations and their correspondence treatment, the main treatment studied in the article is marked.
  • Location: The source of the research data.
