How Acquired Immunodeficiency Syndrome Medications Work

Acquired Immunodeficiency Syndrome (AIDS) is a chronic and potentially life-threatening condition caused by the Human Immunodeficiency Virus (HIV). The primary goal of treatment is to suppress HIV replication, thereby preserving the body's immune system.

Treatment with Antiretroviral Therapy (ART)

The gold standard for treating AIDS is Antiretroviral Therapy (ART), which involves a combination of medications that target different stages of the HIV life cycle. ART works by:

• Suppressing viral replication, thereby reducing the amount of virus in the body

• Preserving the immune system's function and preventing further damage to the body's cells

Alternative Therapies for ART-Resistant Patients

For patients who have developed resistance to first-line ART, alternative therapies are available. These include:

• Protease Inhibitors (PIs): second-line therapy that targets the protease enzyme essential for viral replication

• Non-Nucleoside Reverse Transcriptase Inhibitors (NNRTIs): alternative to first-line ART in some cases, targeting the reverse transcriptase enzyme

• Integrase Strand Transfer Inhibitors (INSTIs): third-line therapy for ART-resistant patients, targeting the integrase enzyme essential for viral integration into host cells

Monitoring Treatment Efficacy and Adherence

To ensure effective treatment and prevent resistance development, regular monitoring of HIV RNA levels and CD4 counts is crucial. Diagnostic tests such as HIV RNA PCR and CD4 Count help clinicians assess the effectiveness of ART and make necessary adjustments to the treatment regimen.
