Abstract INTRODUCTION: The objective of this study was to determine the transmitted drug resistance mutations (TDRMs) in newly diagnosed HIV-1 positive patients in Turkey. MATERIALS AND METHODS: The study was carried out between 2009 and 2014 and antiretroviral naive 774 HIV-1 infected patients from 19 Infectious Diseases and Clinical Microbiology Departments in Turkey were included; gender: 664 (86%) male, median age: 37 (range; 1-77), median CD4+T-cell: 360 (range; 1-1320) count/mm(3), median HIV-RNA load: 2.10+E6 (range; 4.2+E2-7.41+E8) IU/mL. HIV-1 drug resistance mutations were detected by population based sequencing of the reverse transcriptase (codon 41-238) and protease (codon 1-99) domains of pol gene of HIV-1, and analyzed according to the criteria by the World Health Organization 2009 list of surveillance drug resistance mutations [1]. RESULTS: The patients had TDRMs to NRTIs (K65R, M184V), NNRTIs (K101E, K103N/S, G190A/E/S, Y181I/C, Y188H/L) and PIs (M46L, I54V, L76V, V82L/T, N83D, I84V, L90M). The prevalence of overall TDRMs was 6.7% (52/774). Resistance mutations were found to be 0.7% (6/774), 4.1% (32/774) and 2.1% (17/774) to NRTIs, NNRTIs and PIs drug groups, respectively. Three patients had NRTIs+NNRTs resistance mutations (M184V+K103N) as multi-class drug resistance. However, thymidine analogue resistance mutations (TAMs) determined two distinct genotypic profiles in the HIV-1 reverse transcriptase: TAM1: M41L, L210W and T215Y, and TAM2: D67N, K70R, K219E/Q, and T215F. The prevalence of TAM1 and TAM2 were 7.7% (60/774) and 4.3% (34/774), respectively. CONCLUSIONS: The TDRMs prevalence of antiretroviral naive HIV-1 infected patients may be suggested current situation of Turkey. These long-term and large-scale results show that the resistance testing must be an integral part of the management of HIV infection in Turkey.

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.
