Cutaneous Lupus Erythematosus in Children

Area of Science:

• Immunodermatology
• Pediatric Autoimmune Diseases

Background:

• Cutaneous lupus erythematosus (CLE) frequently impacts the skin in autoimmune conditions.
• CLE can present with or without systemic involvement, highlighting the need for early detection.
• Preventing complications is particularly vital in pediatric cases of CLE.

Purpose of the Study:

• To provide physicians with a comprehensive overview of pediatric cutaneous lupus.
• This includes familiarizing them with clinical presentation, diagnostic approaches, evaluation methods, and management strategies.

Main Methods:

• A systematic literature search using "cutaneous lupus" was conducted on PubMed.
• The search focused on epidemiology, clinical diagnosis, investigations, comorbidities, and treatment in English literature concerning children.
• A narrative synthesis of included studies (meta-analyses, RCTs, trials, observational studies, reviews) was performed.

Main Results:

• Pathogenesis of CLE involves diverse innate and adaptive immune responses.
• Cutaneous manifestations vary widely, encompassing different subtypes like acute, subacute, and chronic CLE.
• First-line treatments include topical agents (calcineurin inhibitors, corticosteroids) and oral medications (glucocorticoids, antimalarials, hydroxychloroquine).

Conclusions:

• CLE encompasses multiple subtypes with distinct dermatological features in pediatric and adult populations.
• Evolving understanding of molecular targets will likely alter current treatment paradigms.
• Continued research into CLE mechanisms is essential for developing novel pediatric interventions.
