HIV postexposure prophylaxis in the 21st century.

Area of Science:

• Occupational Health
• Infectious Diseases
• Public Health

Background:

• Postexposure prophylaxis (PEP) is the standard of care for occupational human immunodeficiency virus (HIV) exposures.
• Significant advancements have been made in understanding the safety and efficacy of PEP agents.
• Optimal management strategies for healthcare workers (HCWs) exposed to HIV are crucial.

Purpose of the Study:

• To describe the current state of knowledge regarding PEP for occupational HIV exposure.
• To identify key unanswered questions in the field of HIV PEP.
• To summarize fundamental principles for managing HCWs after HIV exposure.

Main Methods:

• Review of current literature on HIV postexposure prophylaxis.
• Synthesis of data on safety and efficacy of PEP regimens.
• Identification of knowledge gaps and future research directions.

Main Results:

• PEP is an established and effective intervention for preventing HIV transmission after occupational exposure.
• Current knowledge highlights the safety profile and potential efficacy of various PEP agents.
• Several critical questions remain regarding optimal PEP duration, drug selection, and long-term outcomes.

Conclusions:

• PEP administration is a critical component of occupational health and safety for HCWs.
• Continued research is needed to refine PEP protocols and address outstanding clinical questions.
• Effective management of HIV-exposed HCWs relies on evidence-based principles and timely intervention.
