Abstract OBJECTIVE: Assess virological failures, analyze the results of resistance testing (RET), and investigate factors associated with acquired drug resistance mutations (aDRM). DESIGN: A retrospective longitudinal cohort study. METHODS: Virological failures (viral load >50 copies/ml) from a cohort of 1130 individuals, diagnosed with HIV-1 in 2010-2018 and followed up until 2020, were included. Demographic, clinical, and virological data were collected. A piecewise exponential additive mixed model was employed to estimate the association of various factors with aDRM. RESULTS: Only 82 individuals had virological failure, 20/82 had multiple virological failures. The majority of virological failures (77%) were men, 48% were Israeli-born,79% were diagnosed in 2010-2014. Only 18% initiated with second-generation integrase-inhibitor (INI) based regimens. Although no baseline differences were identified between those with single and multiple virological failures, the latter had lower CD4 + levels before first virological failure. NRTI M184IV and INI N155H were identified in more than 10% of the cases. In those with additional failures, INI N155H was more prominent in cases with subtype B compared to those with non-B subtypes ( P = 0.039). Diagnoses with CD4 + cell count less than 200 cells/mul and AIDS [hazard ratio = 3.46, 95% confidence interval (95% CI): 1.51-7.92, P = 0.003], second-generation INI at the first virological failure (HR = 0.32, 95% CI: 0.11-0.91, P = 0.033), and RET at baseline (hazard ratio = 0.34, 95% CI: 0.13-0.86, P = 0.022) had a significant and persistent relative effect on aDRM. CONCLUSION: The risk for aDRM is reduced in those who are treated with second-generation INI-based regimens. Diagnosis with low CD4 + cell counts and AIDS is associated with detection of aDRM.

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.
