Abstract OBJECTIVES: The optimal antiretroviral therapy for patients with the M184V/I mutation is not known. The primary objective of this study was to determine the efficacy of various antiretroviral therapies in patients with HIV and the M184V/I mutation based on the number of active antiretroviral agents. METHODS: A retrospective chart review was conducted of 100 treatment-experienced patients harboring the M184V/I mutation seen at an urban HIV clinic. Efficacy was classified as percentage of patients with viral suppression defined as HIV RNA viral load <200 copies/mL at last measurement on current antiretroviral therapy, stratified by the number of active antiretroviral agents. RESULTS: The primary outcome of viral suppression occurred in 70.6% (12/17) of patients on <2 active agents, 77.2% (44/57) on 2-2.5 active agents, and 69.2% (18/26) on 3 active agents. No significant difference was found between viral suppression and patients on <2 and 2-2.5 antiretroviral agents (odds ratio = 0.71, 95% confidence interval = (0.21, 2.39), p = 0.8) or between patients on 3 and 2-2.5 active agents (odds ratio = 0.66, 95% confidence interval = (0.23, 1.88), p = 0.7). The most commonly prescribed regimen consisted of a boosted protease inhibitor with an integrase strand transfer inhibitor and two nucleoside reverse transcriptase inhibitors, one of which being lamivudine or emtricitabine. CONCLUSION: Similar rates of viral suppression were observed in patients regardless of the number of active antiretroviral agents prescribed. Regimens containing less than 3 active agents may maintain virologic suppression in patients with the M184V/I mutation. Further studies are needed to determine optimal antiretroviral therapy for patients with the M184V/I mutation.

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.
