[Autoinflammatory syndromes in childhood]

Area of Science:

• Immunology
• Genetics
• Rheumatology

Context:

• Systemic autoinflammatory diseases (SAIDs) are a diverse group of disorders affecting the innate immune system.
• Characterized by unprovoked, recurrent inflammation impacting multiple organ systems.
• Potential for severe complications like amyloidosis necessitates better understanding and management.

Purpose:

• To review the current understanding of SAID pathogenesis.
• To highlight key genetic and molecular pathways involved in SAIDs.
• To discuss therapeutic strategies, particularly IL-1 inhibition.

Summary:

• SAIDs encompass hereditary and non-hereditary conditions with inflammation of unknown cause.
• Advances in genetics have elucidated pathways like IL-1 activation in diseases such as familial Mediterranean fever and cryopyrin-associated periodic syndrome.
• Interferon-driven pathways are implicated in newer conditions like CANDLE and SAVI.

Impact:

• Improved understanding of SAID pathogenesis guides targeted therapies.
• IL-1 inhibition represents a significant therapeutic advance for many SAIDs.
• Recognition of interferon-driven pathways opens avenues for novel treatments in specific SAIDs.
