[Insulin allergy: how to manage it?]

Area of Science:

• Immunology
• Endocrinology
• Allergology

Background:

• Insulin allergy is a rare but complex condition.
• Hypersensitivity reactions can be triggered by insulin or its additives.
• Immediate, IgE-mediated reactions are the most frequent type.

Purpose of the Study:

• To review current literature on insulin allergy management.
• To outline diagnostic and therapeutic strategies for insulin hypersensitivity.

Main Methods:

• Literature review of available data on insulin allergy.
• Summary of diagnostic approaches including history, examination, and allergological consultation.
• Overview of management options based on reaction type.

Main Results:

• IgE-mediated (Type I) hypersensitivity is the most common form of insulin allergy.
• Management strategies prioritize insulin avoidance if feasible.
• Alternative insulin types or desensitization protocols are considered when treatment is essential.

Conclusions:

• Accurate diagnosis is crucial for effective insulin allergy management.
• A stepwise approach involving avoidance, substitution, or desensitization is recommended.
• Further research may refine management protocols for this rare condition.
