Rabies immunoglobulin overdose in post-exposure prophylaxis

Area of Science:

• Infectious Diseases
• Virology
• Immunology

Background:

• Rabies is a fatal zoonotic viral infection with the highest mortality rate among infectious diseases.
• Post-exposure prophylaxis (PEP) is essential immediately after potential rabies virus exposure.
• Human exposure commonly results from bites by infected animals, particularly dogs.

Purpose of the Study:

• To illustrate the post-exposure prophylaxis (PEP) administered to a non-immunized woman exposed to a dog bite.
• To report on the administration of an overdose of human rabies immunoglobulin (HRIG).
• To assess the safety and effects of an excessive HRIG dose.

Main Methods:

• Case report detailing post-exposure prophylaxis following a dog bite in a traveler.
• Administration of human rabies immunoglobulin (HRIG) and rabies vaccine.
• Monitoring for adverse effects and immune response after HRIG overdose.

Main Results:

• An overdose of human rabies immunoglobulin (HRIG) was administered to the patient.
• No adverse effects were observed following the excessive HRIG dose.
• No suppression of the immune response was detected during follow-up.

Conclusions:

• Accurate drug administration in rabies post-exposure prophylaxis is crucial for patient outcomes.
• An overdose of HRIG may not necessarily lead to adverse events or immune suppression.
• This case underscores the importance of vigilance in medication dosing for rabies prevention.
