Hyperimmunoglobulin D syndrome in childhood

Area of Science:

• Genetics
• Immunology
• Pediatrics

Background:

• Hyperimmunoglobulinemia D and periodic fever syndrome (HIDS) is a genetic autoinflammatory disorder.
• It is characterized by recurrent fevers, rash, arthritis, and gastrointestinal issues, often starting in infancy.
• Frequent attacks significantly impact a child's quality of life and education.

Purpose of the Study:

• To summarize the clinical characteristics and genetic basis of HIDS.
• To review recent therapeutic advancements for managing HIDS attacks.

Main Methods:

• Review of existing literature on HIDS.
• Analysis of clinical manifestations and genetic mutations.
• Evaluation of treatment outcomes for anakinra and etanercept.

Main Results:

• HIDS is caused by mutations in the mevalonate kinase gene.
• Attacks typically begin in the first year of life, often post-vaccination.
• Anakinra and etanercept have demonstrated positive results in managing HIDS symptoms.

Conclusions:

• HIDS is a debilitating autoinflammatory syndrome with a significant genetic component.
• Early diagnosis and intervention are crucial for managing symptoms and improving outcomes.
• Targeted therapies like anakinra and etanercept offer new hope for patients with HIDS.
