Abstract PURPOSE: Cabotegravir/rilpivirine (CAB/RPV) is the first long-acting antiretroviral therapy for patients with human immunodeficiency virus (HIV). It is administered via intramuscular injection into the gluteal muscle, requiring precise technique. We report the case of a patient living with HIV who developed resistance to CAB despite on-time administration of all doses. SUMMARY: A 34-year-old man with a body mass index (BMI) of 38.42 kg/m2 who received therapy with CAB/RPV 600 mg/900 mg intramuscularly every other month for 15 months presented to the clinic for routine HIV care. An HIV viral load obtained just before the visit demonstrated a significant elevation in his viral load, which was previously undetectable. Further testing demonstrated the development of a G118R resistance-associated mutation in the virus with a class-wide effect on integrase inhibitors. Upon review, it was determined that the patient had received all doses of his medication with a 1.5-inch needle rather than the recommended 2-inch needle based on his BMI. He was subsequently switched to darunavir/cobicistat/emtricitabine/tenofovir alafenamide and quickly achieved viral suppression. CONCLUSION: This case demonstrates the potential for patients living with HIV to develop resistance to CAB/RPV despite on-time administration of the medication. Proper administration and timing of antiretroviral therapy for these patients is essential to ensure efficacy and safety in the management of HIV but does not completely prevent development of resistance.

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.
