[Autoimmune blistering dermatoses in children].

Area of Science:

• Dermatology
• Immunology
• Pediatrics

Background:

• Autoimmune blistering skin disorders are rare dermatoses caused by autoantibodies targeting desmosomal and hemidesmosomal molecules.
• While typically affecting adults, these conditions can manifest neonatally or during childhood, necessitating specific diagnostic considerations.

Purpose of the Study:

• To outline diagnostic and therapeutic strategies for autoimmune blistering skin disorders in pediatric patients.
• To emphasize the importance of early diagnosis and appropriate management for optimal child development and minimizing adverse events.

Main Methods:

• Review of diagnostic approaches including immunoserological testing and direct immunofluorescence of skin biopsies.
• Discussion of treatment modalities ranging from first-line topical steroids and dapsone to advanced therapies for refractory cases.

Main Results:

• Transplacental transmission of maternal autoantibodies (IgG) should be considered in neonatal cases.
• Early diagnosis is critical for selecting appropriate treatments, including preliminary enzyme-activity testing.
• Refractory cases may require high-dose intravenous immunoglobulins, plasmapheresis, or targeted immunotherapies.

Conclusions:

• Prompt diagnosis and tailored treatment are essential for managing autoimmune blistering skin disorders in children.
• Comprehensive dermatological support and medical care are vital for ensuring age-appropriate development and mitigating treatment side effects.
