Summary
HIV drug resistance is a growing threat. HIV resistance testing helps clinicians identify resistant strains and tailor treatment, especially for patients with treatment failure or acute infections.
Area of Science:
- Infectious Diseases
- Virology
- Clinical Medicine
Background:
- Antiretroviral therapy has significantly improved HIV treatment outcomes.
- Emergence of drug-resistant HIV strains poses a major challenge to treatment efficacy.
- Drug resistance can undermine decades of progress in managing HIV infection.
Purpose of the Study:
- To highlight the critical role of HIV resistance testing in clinical practice.
- To inform healthcare providers about the indications and importance of resistance testing.
- To emphasize the need for vigilance regarding transmitted drug resistance.
Main Methods:
- Review of current clinical guidelines and recommendations for HIV resistance testing.
- Discussion of the clinical scenarios where resistance testing is indicated.
- Explanation of the types of resistance tests available and their limitations.
Main Results:
- HIV resistance testing is recommended for patients experiencing virologic failure or suboptimal viral load suppression.
- Testing is advised for patients with acute HIV infection due to the risk of transmitting resistant strains.
- Understanding test limitations is crucial for accurate interpretation and treatment decisions.
Conclusions:
- HIV resistance testing is an essential tool for optimizing antiretroviral therapy.
- Early identification of drug resistance is key to preventing treatment failure and transmission.
- All healthcare practitioners managing HIV patients should be aware of resistance testing options.
