[Anaphylaxis after carrying out prick tests].

Area of Science:

• Allergology
• Immunology
• Dermatology

Background:

• Skin prick testing (SPT) is a standard diagnostic tool in allergology.
• While generally safe, rare systemic reactions, including anaphylaxis, have been reported.
• Cat dander allergy is common, often presenting with respiratory and ocular symptoms.

Observation:

• A 23-year-old female with a history of asthma and rhinoconjunctivitis experienced anaphylaxis post-SPT.
• The reaction occurred 20 minutes after SPT using a cat dander extract.
• Symptoms included severe ocular irritation, dysphonia, and a sensation of pharyngeal occupation.

Findings:

• The patient developed anaphylaxis with hemodynamic compromise following SPT.
• Cat dander extract was identified as the trigger for the severe systemic reaction.
• This case underscores the potential for serious adverse events during SPT.

Implications:

• SPT should be conducted by trained specialists in facilities equipped to manage anaphylaxis.
• Awareness of potential systemic reactions is crucial for patient safety during allergy testing.
• Prompt recognition and management are vital for patients experiencing anaphylaxis after SPT.
