Summary
Early antiretroviral prophylaxis after human immunodeficiency virus (HIV) exposure significantly reduces infection risk. Current guidelines recommend specific drug regimens, with interferon alfa-2b considered for massive exposures.
Area of Science:
- Infectious Diseases
- Virology
- Public Health
Background:
- Parenteral exposure to human immunodeficiency virus (HIV) poses a significant infection risk.
- Early intervention is crucial for preventing HIV transmission.
- Current prophylaxis strategies aim to minimize post-exposure infection rates.
Purpose of the Study:
- To summarize the efficacy of early prophylaxis in preventing HIV infection.
- To outline current recommendations for post-exposure prophylaxis (PEP) regimens.
- To highlight the importance of co-testing for other infections.
Main Methods:
- Review of current Centers for Disease Control and Prevention (CDC) guidelines for HIV PEP.
- Discussion of recommended antiretroviral drug combinations.
- Consideration of adjunctive therapies like interferon alfa-2b for specific exposure scenarios.
Main Results:
- Early prophylaxis can reduce HIV infection risk by up to 10-fold.
- Recommended PEP regimens include two nucleoside antiretroviral drugs, potentially with a protease inhibitor.
- Interferon alfa-2b may offer benefits in cases of massive HIV exposure.
Conclusions:
- Post-exposure prophylaxis should be offered after all parenteral HIV exposures.
- Comprehensive testing for HIV, hepatitis B, hepatitis C, and syphilis is essential for both source patients and exposed individuals.

01:10Retrovirus Life Cycles
Retroviruses have a single-stranded RNA genome that undergoes a special form of replication. Once the retrovirus has entered the host cell, an enzyme called reverse transcriptase synthesizes double-stranded DNA from the retroviral RNA genome. This DNA copy of the genome is then integrated into the host’s genome inside the nucleus via an enzyme called integrase. Consequently, the retroviral genome is transcribed into RNA whenever the host’s genome is transcribed, allowing the retrovirus to...
01:25Transmission-based Precautions II: Airborne and Protective Environment
Transmission-based precautions are for patients infected or suspected to be infected (or colonized) with organisms posing a significant risk to others. The transmission precautions include airborne and protective environment precautions.
Airborne precautions:
Use airborne precautions when treating patients known or suspected to have diseases that spread through the air—for example, tuberculosis or measles. These organisms are present in smaller droplets expelled by an infected person and...

01:26Standard Precaution
Standard precautions are the minimum infection control safeguards used while caring for all patients, irrespective of their disease condition. They help prevent the spread of common infectious microorganisms to healthcare workers, patients, and visitors in all healthcare settings.

Transmission-based precautions are for patients known to be infected or suspected to be infected or colonized with organisms that pose a significant risk to others. Some transmission-based precautions include contact, enteric, and droplet.
Contact Precautions:
Contact precautions are the measures taken to prevent the transmission of infectious agents, especially epidemiologically important microorganisms such as MRSA or influenza, primarily transmitted through direct or indirect contact with an...

01:26Sexually Transmitted Infections
Sexually transmitted infections (STIs) are diseases transmitted primarily through unsafe sexual interactions. Bacteria, viruses, or parasites cause them and can result in severe health complications if untreated.ChlamydiaThe bacterium Chlamydia trachomatis is responsible for the disease Chlamydia, the most common STI in the United States. This peculiar pathogen requires human cells to reproduce, residing intracellularly. The initial infection often goes unnoticed because it typically does not...
01:27Cryptococcal Meningitis
Cryptococcal meningitis is a life-threatening opportunistic infection predominantly associated with HIV/AIDS, accounting for over 100,000 deaths annually worldwide. However, it also affects individuals with other forms of immunosuppression, including those undergoing immunosuppressive therapy, organ transplant recipients, patients with innate immunodeficiencies, and individuals with hematological disorders. The infection is caused mainly by Cryptococcus neoformans and Cryptococcus gattii,...
