[Allergy and autoimmunity: Molecular diagnostics, therapy, and presumable pathogenesis]

Area of Science:

• Immunology
• Pathology
• Molecular Diagnostics

Background:

• Allergic and autoimmune diseases involve immunopathological reactions to external (allergens) or internal (autoantigens) substances.
• Both conditions are considered variations of hypersensitivity reactions, indicating shared underlying mechanisms.
• Early diagnosis is essential for a significant portion of the adult and pediatric population affected by these immune system disorders.

Purpose of the Study:

• To review current data on molecular diagnostics and therapy for allergic and autoimmune diseases.
• To discuss the fundamental similarities and differences in the developmental mechanisms of these conditions.
• To highlight the importance of multi-stage molecular diagnostics due to antibody diversity and diagnostic challenges.

Main Methods:

• Literature review of existing data on molecular diagnostics and therapy.
• Comparative analysis of mechanisms in allergic and autoimmune diseases.
• Discussion of diagnostic strategies, including screening and confirmatory studies.

Main Results:

• Identified common underlying mechanisms in allergic and autoimmune diseases, classifying them as hypersensitivity reactions.
• Highlighted the diversity of antibodies involved, complicating clinical diagnosis.
• Emphasized the need for staged molecular diagnostic approaches.

Conclusions:

• Allergic and autoimmune diseases share common hypersensitivity mechanisms despite differing antigen targets.
• Molecular diagnostics are vital for accurate and timely identification of these conditions.
• Further research into shared pathways can inform integrated therapeutic strategies.
