Summary
Antiretroviral drug resistance testing is crucial for managing human immune deficiency virus type-1 (HIV-1) infection. This review details available resistance assays and their clinical use.
Area of Science:
- Virology
- Infectious Diseases
- Pharmacology
Background:
- Antiretroviral drugs are key in managing HIV-1 by lowering viral load and boosting immunity.
- Antiretroviral drug resistance significantly hinders effective HIV-1 treatment.
- Resistance testing is now integral to HIV-1 management protocols.
Purpose of the Study:
- To review current methods for detecting antiretroviral drug resistance in HIV-1.
- To outline the clinical utility and limitations of available resistance assays.
- To emphasize the importance of accurate interpretation of assay results.
Main Methods:
- Genotypic assays detect specific drug resistance mutations.
- Phenotypic assays measure drug susceptibility directly.
- This review synthesizes information on various resistance testing methodologies.
Main Results:
- Genotypic and phenotypic assays have demonstrated reliability and clinical utility.
- Accurate interpretation requires understanding assay complexities, updated mutation lists, and algorithms.
- Clinical application necessitates consideration of patient profile by experienced practitioners.
Conclusions:
- Antiretroviral drug resistance testing is essential for optimizing HIV-1 therapy.
- Understanding and applying resistance assay results are critical for clinicians.
- Continued refinement of assays and interpretation guidelines is important for patient care.
