Effective antiretroviral therapy (ART) for human immunodeficiency virus (HIV) infection suppresses viral replication, improving immune function and life expectancy. Current ART regimens, often including integrase inhibitors, are highly effective for managing HIV.
Area of Science:
- Infectious Diseases
- Virology
- Pharmacology
Background:
- Human immunodeficiency virus (HIV) infection remains a significant global health challenge.
- Antiretroviral drugs are crucial for managing HIV by inhibiting viral replication.
- Six mechanistic classes of antiretroviral drugs exist, targeting different stages of the HIV lifecycle.
Purpose of the Study:
- To review the development and efficacy of antiretroviral therapy (ART) for HIV infection.
- To highlight the current recommended ART regimens and their components.
- To discuss the monitoring and management of virologic failure in patients on ART.
Main Methods:
- Review of randomized clinical trials and Food and Drug Administration (FDA) approvals of antiretroviral drugs.
- Analysis of current preferred ART regimens, emphasizing integrase inhibitors and nucleoside reverse-transcriptase inhibitors.
- Description of strategies for managing virologic failure, including drug resistance testing.
Main Results:
- Antiretroviral therapy (ART) effectively suppresses HIV replication, leading to improved immune function, reduced morbidity and mortality, and prevention of transmission.
- The majority of patients on current ART regimens achieve durable viral suppression below detectable levels.
- Life expectancy for individuals with HIV consistently adhering to ART approaches that of the general population.
Conclusions:
- Antiretroviral therapy (ART) is recommended for all individuals with HIV infection.
- Initial preferred ART regimens are potent, convenient, and designed to minimize side effects and resistance.
- Effective management and monitoring of HIV infection with ART have transformed patient outcomes, significantly improving quality of life and longevity.
