Summary
Highly active antiretroviral therapy for human immunodeficiency virus (HIV) has high failure rates. Drug resistance and salvage therapy challenges necessitate new treatment strategies for effective HIV management.
Area of Science:
- Virology
- Immunology
- Pharmacology
Background:
- Highly active antiretroviral combination therapies have significantly reduced HIV morbidity and mortality.
- However, treatment failure rates remain high (20-50%), often due to demanding drug regimens and potential for resistance.
- Continuous detection of HIV RNA above 50 copies/mL predicts suboptimal response and increasing viral loads.
Purpose of the Study:
- To review the challenges in human immunodeficiency virus (HIV) treatment failure.
- To discuss the role of drug susceptibility testing and salvage therapies.
- To highlight the need for new compounds and treatment strategies for drug-resistant HIV.
Main Methods:
- Literature review of current human immunodeficiency virus (HIV) treatment outcomes.
- Analysis of factors contributing to treatment failure and drug resistance.
- Evaluation of salvage therapy approaches and their success rates.
Main Results:
- Treatment failure in human immunodeficiency virus (HIV) occurs frequently, necessitating careful management.
- Drug susceptibility testing is increasingly valuable, particularly for first-time treatment failures.
- Salvage therapies, often involving multiple drugs, show variable virological success (50-80% failure) but can achieve immunological and clinical stability.
Conclusions:
- Despite advances, human immunodeficiency virus (HIV) treatment failure remains a significant clinical challenge.
- Optimizing salvage therapies requires new drug classes and personalized approaches based on resistance profiles.
- Further research into novel compounds is crucial for managing multi-drug-resistant HIV.
