slide14. Pathophysiology: Type I Hypersensitivity:
IgE-mediated allergic reaction
Mast cell degranulation releases inflammatory mediators
Result: Angioedema, skin reactions, and more
Insulin’s Role:
A component within insulin must be the source

slide20. Structuring a Protocol No current treatment guidelines for insulin allergies
Recent study shows a workflow for management:
Step 1: Determine allergy sensitivity.
Step 2: Evaluate the severity of symptoms.
Step 3: Are any alternative agents feasible?
Step 4: What change of insulin is possible?
Step 5: Monitor for efficacy and safety. Haastrup MB, Henriksen JE, Mortz CG, Bindslev-Jensen C. Insulin allergy can be successfully managed by a systematic approach. Clinical and Translational Allergy. 2018;8(1). doi:https://doi.org/10.1186/s13601-018-0223-x<br>

slide26. Future Considerations<br>
slide27. Takeaways Insulin allergies are rare. There is no correlating factor with strong evidence to be labeled a true risk factor.
Insulin hypersensitivity presents as immediate or delayed. Reactions are either local to the injection site or systemic and are mediated by mast cell degranulation.
Driving mediators of insulin allergy include direct reaction to insulin structure, presence of protamine, and/or excipients.
There are methods to diagnose insulin allergy via “prick” tests covered under insurance. These can determine specific insulin agent sensitivity.
The first-line option for treatment is identifying the most likely antigen-inducing reaction, then switching to an agent without said antigen.
If switching is unsuccessful, move to insulin desensitization. This can be done subcutaneously or through a pump.
Our patient today has tolerated Basaglar since 10/2023. An upward titration would benefit BG and A1c control without any evidence of increasing risk for allergic reactions.<br>
