Mastocytosis and allergic diseases

Area of Science:

• Hematology
• Immunology
• Allergy and Immunology

Background:

• Mastocytosis is a clonal disorder involving mast cell proliferation in tissues like skin and bone marrow.
• Clinical manifestations are diverse, with anaphylaxis being the most severe, triggered by mediator release from mast cells.

Purpose of the Study:

• To review anaphylaxis triggers in mastocytosis patients.
• To discuss prevention strategies for severe reactions, including immunotherapy and trigger avoidance.
• To highlight the scarcity of data on drug-induced anaphylaxis in mast cell disorders.

Main Methods:

• Review of published literature on mastocytosis and anaphylaxis.
• Analysis of common anaphylaxis triggers in adults with mastocytosis.
• Discussion of risk mitigation strategies for systemic reactions during general anesthesia.

Main Results:

• Hymenoptera stings are the most frequent anaphylaxis trigger in adults with mastocytosis, followed by foods and drugs.
• Lifelong immunotherapy is effective for venom-allergic patients.
• Data on drug anaphylaxis in mast cell disorders are limited, precluding clear recommendations.

Conclusions:

• Recognizing and avoiding anaphylaxis triggers is crucial for mastocytosis patients.
• Venom immunotherapy is a highly effective preventive measure.
• Further research is needed to establish guidelines for drug-induced anaphylaxis management in mast cell disorders.
