Abstract BACKGROUND: Antiretroviral (ARV) therapy extends life for persons living with HIV. Antiretroviral treatment (ART) has been rapidly expanding coverage around the world, including in Iran. However, ART drug resistance also rapidly develops with expanding use and limits effectiveness and treatment options. The aim of this study was to monitor the appearance of new mutations conferring HIV pretreatment drug resistance in the treatment of naive patients with HIV in Iran. MATERIALS AND METHODS: Blood samples were obtained from ARV treatment-naive patients from 8 different provinces in Iran in 2016 for genotyping for drug resistance mutations. RESULTS: Sequences were successfully obtained from 90 specimens. Of these, 2 (2%) mutations conferring resistance to protease inhibitors, 2 (3%) conferring resistance to nucleoside reverse transcriptase inhibitors (NRTIs), and 9 (13%) conferring resistance to non-NRTI (NNRTI) were detected. Any ARV-resistant drug mutation was found in 11 patients (12%). CONCLUSION: Nearly one in 8 ARV-naive patients had mutations associated with NNRTI resistance in diverse areas of Iran in 2016. Iranian ARV therapy guideline for HIV could consider non-NNRTI-based first-line therapies and expand routine drug resistance testing before treatment initiation as according to HIV drug resistance recommendations of the World Health Organization.

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.
