Study Notes
HIV/AIDS and Immunodeficiency
- HIV is a virus that weakens the immune system
- AIDS is a syndrome, not a virus. It is caused when the immune system is severely damaged by HIV
- Immunodeficiency happens when the body's immune system becomes weakened and less capable of fighting off infections, cancers, or other diseases like healthy individuals' immune systems do
- Primary immunodeficiency is genetic. Secondary immunodeficiency can be caused by environmental factors such as HIV, AIDS, or malnutrition.
- Immunodeficiency is a large range of infections, cancers, and other diseases that individuals with a healthy immune system can fight off
- There are different stages of HIV infection:
- Stage 1: Seroconversion Illness (up to 6 weeks). Symptoms similar to influenza (fever, rash, sore throat)
- Stage 2: Asymptomatic Stage. Patient feels fine. The virus is active and damaging the immune system
- Stage 3: Symptomatic HIV. The longer the patient lives with HIV without treatment, the greater the risk of developing infections their immune system can't fight
- Stage 4: Late-Stage HIV. Severe opportunistic infections and cancers occur due to significant immune system damage
HIV-related Illnesses (AIDS-defining)
- Kaposi's sarcoma (KS): A cancer caused by a herpes virus (HHV-8). The virus initially affects endothelial cells within blood vessels and lymphatic vessels. This leads to tumors, and it may appear as skin lesions or in the mouth.
- Candidiasis (Thrush): A fungal infection caused by Candida yeast. It can affect the mouth, esophagus, bronchi, trachea, and lungs. Commonly presented via white plaques on the tongue or throat.
- Tuberculosis (TB): A bacterial infection often affecting the lungs. HIV increases the risk of TB infection.
- Cryptococcal meningitis: A fungus-related brain infection. It is more common and severe in people living with HIV.
- Hairy leukoplakia: White patches on the tongue caused by the Epstein-Barr virus. It is more frequent in people with weakened immune systems like HIV patients.
Transmission of HIV
- HIV is present in bodily fluids such as semen, vaginal fluids, blood, and breast milk
- The most common way people in the UK get HIV is via unprotected anal or vaginal sex
- The risk of HIV transmission through oral sex is very low
- HIV is not transmitted via sweat, urine, or saliva.
Risk Factors for HIV
- Having another sexually transmitted infection (STI): STIs can increase the risk of HIV transmission
- Sharing contaminated needles or syringes: Sharing needles or syringes with an infected person can transmit HIV and other bloodborne infections.
- Receiving unsafe injections, blood transfusions, and tissue transplantation: Unsafe procedures can also put individuals at risk.
- Needle stick injuries: While not as common, needle stick injuries with contaminated needles can transmit several blood-borne infections
Diagnosing HIV
- It is important to seek medical advice immediately if concerned about possible HIV exposure
- If a needle stick occurs, occupational health must be contacted immediately, or A&E if out of hours.
- HIV tests are necessary for diagnosis, and should be repeated at specific intervals if negative
- Results are given as the number of copies of HIV per milliliter of blood.
Treatment for HIV
- Antiretroviral therapy (ART) is used to treat HIV
- The goal of ART is to reduce (or suppress) the viral load to an undetectable level, decreasing the risk of transmission and improving health outcomes. The medication's efficacy is typically measured by the viral load.
Viral Load
- Viral load is the amount of HIV in the blood
- A viral load test measures the number of HIV particles in a blood sample
- The results from the testing are expressed as the number of copies of HIV per milliliter of blood
- An undetectable viral load means the virus is present in low enough concentrations in the body that it cannot be detected by traditional test methods. This essentially means that a person cannot transmit the virus to others.
Pre-Exposure Prophylaxis (PrEP)
- PrEP is a strategy for preventing HIV infection in people at a higher risk of contracting the disease
Post-Exposure Prophylaxis (PEP)
- PEP treatment must be initiated within 72 hours of exposure for maximum effectiveness. This consists of a 28-day regimen of ARV drugs
- It is recommended to take PEP in cases of potential HIV exposure via occupational hazards, or non-occupational exposures
HIV Statistics
- In 2019, the estimated number of people living with HIV in the UK was 105,200
- 94% are diagnosed. 6% do not know that they have the virus.
- 98% of diagnosed HIV patients in the UK are on treatment, with 97% of those who are treated having a non-detectable viral load making them unlikely to transmit the virus.
Learning Outcomes
- There were various general learning outcomes (1.1.2, 1.1.3, and so on.) Note those as relevant to your studies. Specific learning objectives were available but not listed.
Additional Information
- Patient/client care and communication guidelines are essential to remember in providing aid to individuals experiencing any health concern, particularly with respect to HIV or AIDS. Respect the patient's wishes.
- Avoid stigmatizing language, attitudes, or practices when dealing with HIV or AIDS patients.
- There are multiple forms of HIV care and treatment (PEP, PrEP, etc)
