As we approach the end of 2023, the ongoing battle against HIV/AIDS remains a critical health concern. Since the epidemic's onset in the early 1980s, more than 88 million people have been diagnosed, with over 42 million lives lost due to the disease. Today, nearly 40 million individuals globally are living with HIV, including approximately 1.2 million in the United States alone. The active engagement of future healthcare professionals, particularly student pharmacists, is essential to combat this epidemic.

Understanding HIV/AIDS: The Basics

HIV, or Human Immunodeficiency Virus, compromises the immune system by targeting CD4+ cells, which are crucial for a healthy immune response. A normal CD4+ cell count ranges from 500 to 1500 cells/mm3, but when the count falls below 200 cells/mm3 due to untreated HIV, a person may be diagnosed with AIDS (Acquired Immunodeficiency Syndrome). This progression increases vulnerability to opportunistic infections such as tuberculosis and candidiasis.

Transmission mainly occurs through bodily fluids, highlighting the crucial need for education around safe practices, especially among high-risk populations, including intravenous drug users and individuals engaging in unprotected sex. In the initial weeks post-infection, flu-like symptoms may appear but often go unrecognized.

The Importance of Regular HIV Testing

The Centers for Disease Control and Prevention (CDC) recommend that everyone aged 13 to 64 gets tested for HIV at least once a year. Those at higher risk, such as men who have sex with men, Black/African Americans, and individuals who inject drugs, should consider getting tested every 3 to 6 months. Quick testing options are available, including the OraQuick In-Home HIV Test, which provides results within 20 minutes and is accessible at many retail outlets.

Furthermore, participating in clinic testing can offer comprehensive support, often at no cost. The CDC's GetTested website assists in locating local testing sites, emphasizing the role student pharmacists can play in helping patients navigate available resources.

Antiretroviral Therapy: The Lifeline for HIV Patients

The Department of Health and Human Services advocates antiretroviral therapy (ART) for everyone with HIV to lower morbidity and mortality rates and reduce transmission. A combination of at least two FDA-approved medications has proven effective in helping patients achieve an undetectable viral load, meaning they cannot sexually transmit the virus, a concept summarized by the phrase U=U (Undetectable = Untransmittable).

Pharmacy students must familiarize themselves with various classes of antiretroviral medications, which include:

- **Nucleoside/Nucleotide Reverse Transcriptase Inhibitors (NRTIs)**: Important for treatment regimens but require careful patient assessment due to potential side effects.

- **Integrase Inhibitors**: Today’s frontline treatments with fewer side effects, essential for improving patient adherence.

- **Non-nucleoside Reverse Transcriptase Inhibitors (NNRTIs)**: These medications can affect the central nervous system, necessitating specific administration guidelines.

- **Protease Inhibitors**: Require taking with food, reflecting the importance of patient education regarding medication regimens.

Preventive Measures: PrEP and PEP

Pre-exposure prophylaxis (PrEP) is recommended for individuals at high risk of HIV, reducing the chance of contracting the virus by up to 99% with consistent use. Approved medications include Truvada and Descovy, both requiring regular testing for HIV infection. Notably, Apretude, administered via injection every two months, provides an alternative for those who struggle with daily pill adherence.

Post-exposure prophylaxis (PEP) must be taken within 72 hours of potential HIV exposure and administered for 28 days. Both occupational and non-occupational scenarios can warrant PEP, with access becoming increasingly available through pharmacies in states like New York and California.

A Call to Action for Future Pharmacists

As future healthcare leaders, pharmacy students must embrace their role in ending the HIV/AIDS epidemic. Understanding transmission and prevention methods, promoting regular testing, and educating on ART, PrEP, and PEP are vital components of patient care.

While a cure for HIV remains elusive, an early diagnosis and effective treatment allow individuals to lead full, healthy lives. Student pharmacists can be indispensable allies in this fight—helping bridge gaps in healthcare, advocating for vulnerable populations, and making a significant impact on public health.

Together, we can turn the tide against HIV/AIDS, one student pharmacist at a time!
