Prevalence and burden of pediatric-onset systemic lupus erythematosus

Area of Science:

• Rheumatology
• Pediatric Autoimmunity
• Chronic Disease Management

Background:

• Systemic lupus erythematosus (SLE) is a chronic autoimmune disease with variable presentation.
• Pediatric-onset SLE (pSLE) accounts for 10-20% of cases and exhibits greater severity and faster damage accrual than adult-onset SLE.
• Disease expression in pSLE varies by ethnicity, with white patients often experiencing a milder course.

Purpose of the Study:

• To summarize the clinical course, damage patterns, and morbidities associated with pediatric-onset SLE.
• To highlight the long-term consequences and psychosocial impact of pSLE.
• To emphasize the need for further research in pSLE.

Main Methods:

• Review of existing literature on pediatric-onset SLE.
• Analysis of disease progression, damage accrual, and associated morbidities.
• Examination of psychosocial factors in pSLE patients.

Main Results:

• Most pSLE patients develop damage within 5-10 years, affecting musculoskeletal, ocular, renal, and neuropsychiatric systems.
• Improved management leads to longer survival but increased cumulative disease damage.
• Premature atherosclerosis and osteoporosis are significant, prevalent morbidities in pSLE, increasing risks for cardiovascular events and fractures.

Conclusions:

• pSLE is an incurable, severe disease impacting children during critical developmental stages.
• Increased longevity in pSLE patients results in higher rates of premature atherosclerosis and osteoporosis.
• Further large-scale, long-term studies are essential for improved pSLE prognosis and tailored treatment development.
