Abstract Nonnucleoside reverse transcriptase inhibitor-drug resistance mutations (DRM) are increasingly reported in Africans failing their first antiretroviral regimen. The Phidisa II trial randomized treatment-naive participants to lopinavir/ritonavir or efavirenz with stavudine + lamivudine or zidovudine + didanosine. We report the prevalence of DRM in subjects who achieved HIV RNA <400 copies per milliliter at 6 months, but subsequently had 2 consecutive HIV RNA >1000 copies per milliliter. Sixty-eight participants fulfilled the inclusion criteria. nonnucleoside reverse transcriptase inhibitor-DRM were found in 17 of 36 (47.2%) efavirenz recipients, and M184V/I mutation in 14 of 40 (35.0%) lamivudine recipients. No protease inhibitor mutation was identified in 38 lopinavir/ritonavir recipients. This is one of the first studies in Africa confirming the paucity of protease inhibitor-associated DRM despite virologic failure.

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.
Literature Information
  • Sequence Data: The study provides the data accession number.
