Study Notes
Definition
Post-exposure prophylaxis (PEP) is a preventive treatment started immediately after exposure to a pathogen to prevent infection or disease.
Types of PEP
- HIV PEP: Antiretroviral therapy (ART) taken within 72 hours of exposure to HIV to prevent infection.
- Rabies PEP: Immediate wound cleaning, followed by a dose of rabies immune globulin and a series of rabies vaccinations to prevent rabies infection.
- Hepatitis PEP: Administration of hepatitis A or B immune globulin and/or vaccination to prevent hepatitis infection.
When to Use PEP
- Occupational exposure: Healthcare workers exposed to bodily fluids, needles, or other sharp objects.
- Sexual assault: Victims of sexual assault exposed to bodily fluids.
- Animal bites: People bitten or scratched by animals potentially infected with rabies or other diseases.
- Needlestick injuries: Individuals exposed to contaminated needles or sharps.
Key Principles
- Timeliness: PEP should be initiated as soon as possible after exposure, ideally within 1-2 hours.
- Compliance: Completing the full treatment regimen is crucial for effective prevention.
- Risk assessment: Healthcare professionals should assess the risk of transmission and determine the appropriate PEP regimen.
HIV PEP Regimen
- Triple therapy: Combination of three antiretroviral medications taken for 28 days.
- Initiation: Started within 72 hours of exposure, but the sooner the better.
- Monitoring: Regular blood tests to monitor for HIV infection and potential side effects.
Importance of PEP
- Prevents infection: PEP can significantly reduce the risk of infection or disease transmission.
- Reduces morbidity and mortality: Timely and effective PEP can prevent serious health consequences.
- Enhances public health: PEP contributes to the control and prevention of infectious diseases.
