Hypothesis
Lower DC density in deeper cutaneous compartments and/or different DC subsets may explain the absence of clinical reactivity against prilocaine after deep subcutaneous injection.
Conclusion
The study demonstrates that the route of allergen administration affects the immunologic outcome, leading to either allergic reactions or clinical tolerance.
Supporting Evidence
- Prilocaine allergy was confirmed by positive skin testing and subcutaneous provocation.
- The patient tolerated deep subcutaneous injections of prilocaine without allergic reactions.
- Different local anesthetics showed no cross-reactivity in the patient.
Takeaway
This study shows that how and where you get an allergy shot can change whether you have a reaction or not.
Methodology
The patient underwent skin testing and provocation testing with different local anesthetics to evaluate allergic reactions.
Limitations
The study is based on a single case report, limiting generalizability.
Participant Demographics
A 42-year-old female patient.
