Diagnosing HIV HIV diagnosis is primarily conducted through testing of blood or saliva, with several types of tests available:

  • Antigen-Antibody Tests: These tests detect antigens, components of the HIV virus, and antibodies produced by the immune system in response to HIV. Antigens typically appear within a few weeks post-exposure, while antibodies may take longer to develop, resulting in a positive test 2 to 6 weeks after exposure.

  • Antibody Tests: Focused on identifying antibodies against HIV in blood or saliva, these tests are commonly used for rapid HIV testing, including home self-tests. A positive result may not be evident until 3 to 12 weeks post-exposure.

  • Nucleic Acid Tests (NATs): These tests measure the viral load, the quantity of the virus present in the blood, and are often the first to indicate a positive result after HIV exposure.

Staging and Treatment Planning Upon an HIV diagnosis, it’s essential to consult a specialist for further testing and treatment planning, which may include:

  • CD4 T Cell Count: Monitoring the number of CD4 T cells, which are targeted by HIV, helps determine the stage of infection. AIDS is diagnosed when the count falls below 200.

  • Viral Load Testing: This evaluates the amount of HIV in the blood, aiming for an undetectable viral load post-treatment initiation.

  • Medicine Resistance Testing: Identifies resistance to specific HIV medications, informing treatment choices.

Additional Testing for Complications Healthcare professionals may also recommend tests for other conditions that can occur alongside HIV, such as:

  • Tuberculosis
  • Hepatitis B and C
  • Sexually Transmitted Infections (STIs)
  • Liver or kidney damage
  • Urinary tract infections
  • Cervical and anal cancers
  • Cytomegalovirus
  • Toxoplasmosis

Treatment Approach While there is no cure for HIV/AIDS, antiretroviral therapy (ART) can manage the infection effectively. ART typically combines multiple medications from different classes to reduce HIV levels in the blood, prevent the development of resistant strains, and maintain viral suppression. The regimen often includes two drugs from one class and a third from another, taken as a single daily pill.

Classes of Anti-HIV Medications and Treatment Adherence

Medication Classes:

  • Non-nucleoside Reverse Transcriptase Inhibitors (NNRTIs): These medications deactivate a protein essential for HIV replication.

    • Examples: Efavirenz, rilpivirine (Edurant), doravirine (Pifeltro).

  • Nucleoside or Nucleotide Reverse Transcriptase Inhibitors (NRTIs): These drugs mimic the building blocks HIV requires, but are defective, hindering the virus’s ability to replicate.

    • Examples: Abacavir (Ziagen), tenofovir disoproxil fumarate (Viread), emtricitabine (Emtriva), lamivudine (Epivir), zidovudine (Retrovir).

  • Protease Inhibitors (PIs): These inhibit the HIV protease protein, another critical component for viral replication.

    • Examples: Atazanavir (Reyataz), darunavir (Prezista), lopinavir-ritonavir (Kaletra).

  • Integrase Inhibitors: They block integrase, a protein HIV uses to integrate its genetic material into CD4 T cells.

    • Examples: Bictegravir sodium-emtricitabine-tenofovir alafenamide fumarate (Biktarvy), raltegravir (Isentress), dolutegravir (Tivicay), cabotegravir (Vocabria).

  • Entry or Fusion Inhibitors: These prevent HIV from entering CD4 T cells.

    • Examples: Enfuvirtide (Fuzeon), maraviroc (Selzentry), ibalizumab-uiyk (Trogarzo), fostemsavir (Rukobia).

Adherence to Treatment:

  • Antiretroviral Therapy (ART): It’s crucial for everyone with HIV to be on ART, regardless of CD4 T cell count or symptoms.
  • Undetectable Viral Load: Consistent ART use leading to an undetectable viral load is key to maintaining health.
  • Medication Adherence: To ensure ART effectiveness, it’s important to take medications as prescribed without missing doses.
  • Benefits of Adherence:
    • Strengthens the immune system.
    • Reduces the risk of infections.
    • Prevents the development of treatment-resistant HIV strains.
    • Decreases the likelihood of transmitting HIV to others.

Managing Treatment:

  • Healthcare Consultation: Discuss potential side effects and any personal issues that may impact adherence with a healthcare professional.
  • Regular Checkups: Maintain frequent appointments to monitor health and treatment efficacy.

Potential Side Effects:

  • Nausea, vomiting, or diarrhea.
  • Increased risk of heart disease.
  • Possible kidney and liver damage.
  • Bone weakening or loss.
  • Abnormal cholesterol levels.
  • Elevated blood sugar.
  • Cognitive, emotional, and sleep disturbances.

Managing HIV Treatment and Lifestyle Considerations

Treatment for Age-Related Diseases:

  • Medication Interactions: Some medicines commonly used for age-related conditions (such as heart, bone, or metabolic issues) may not be compatible with anti-HIV medications. Always inform other healthcare professionals about your HIV therapy to ensure safe combinations.

Monitoring Treatment Response:

  • Regular follow-up appointments are essential to assess your response to HIV treatment.
  • Viral Load and CD4 T Cell Counts: These measures help gauge treatment effectiveness. The goal is to achieve an undetectable viral load, even though HIV remains in your body.

Lifestyle and Home Remedies:

  • Nutrition: Consume fresh fruits, vegetables, whole grains, and lean protein to support your immune system and maintain energy levels.
  • Food Safety: Avoid raw meat, eggs, and untreated dairy products. Cook meat thoroughly and drink safe water.
  • Vaccinations: Stay up-to-date with vaccinations, including those for pneumonia, influenza, COVID-19, and other preventable diseases.
  • Pet Care: Be cautious with pets, as some animals may carry parasites harmful to people with HIV.

Alternative Medicine and Supplements:

  • Supplement Considerations: While evidence is limited, some supplements may be helpful:
    • Acetyl-L-carnitine: Used for neuropathy treatment.
    • Whey protein and amino acids: May aid weight gain.
    • Probiotics: Saccharomyces boulardii for HIV-related diarrhea.
    • Vitamins and minerals: Consult your healthcare professional to address deficiencies safely.

Note: Always consult your healthcare professional before taking supplements or alternative therapies to ensure compatibility with your HIV treatment. If you have specific concerns, feel free to ask.

Supplements and Lifestyle Considerations for HIV/AIDS

Supplements to Approach with Caution:

  • St. John’s Wort: Used for depression, but it can significantly reduce the effectiveness of certain anti-HIV medications.
  • Garlic Supplements: While garlic itself may boost the immune system, garlic supplements can interfere with anti-HIV drugs. Consuming garlic in food appears to be safe.
  • Red Yeast Rice Extract: Used to lower cholesterol, but avoid it if you’re taking protease inhibitors or statins.

Mind-Body Practices:

  • Practices like yoga, meditation, and massage can reduce stress, enhance relaxation, and improve quality of life for those living with HIV/AIDS.

Coping and Support:

  • Receiving a life-threatening diagnosis can be distressing. Seek support from social workers, counselors, or nurses at HIV/AIDS clinics.
  • Services may include transportation assistance, housing support, child care, employment guidance, and financial help.
