Collagen disease in children. A review of 71 cases

Area of Science:

• Pediatric Rheumatology
• Connective Tissue Diseases
• Autoimmune Disorders

Background:

• Systemic lupus erythematosus (SLE), dermatomyositis, and scleroderma are significant autoimmune conditions affecting children.
• Pediatric SLE presents unique challenges with a generally poorer prognosis compared to adult-onset disease.

Purpose of the Study:

• To retrospectively analyze the clinical characteristics, prognosis, and treatment outcomes of children diagnosed with SLE, dermatomyositis, or scleroderma.
• To identify factors associated with mortality and morbidity in pediatric SLE.

Main Methods:

• Retrospective chart review of 71 children diagnosed with SLE (39), dermatomyositis (25), or scleroderma (7).
• Analysis of disease onset, clinical manifestations, treatment regimens, and patient outcomes.

Main Results:

• Children with SLE exhibited greater severity and poorer prognosis than those with dermatomyositis or scleroderma, and worse than adult SLE patients.
• Earlier age of onset, gastrointestinal bleeding, renal, and cardiac abnormalities were associated with increased mortality in pediatric SLE.
• Hormonal influences may play a role, suggested by a peak incidence of SLE near puberty.
• Treatment advancements, particularly corticosteroids and antimetabolites, improved survival and reduced morbidity over time.

Conclusions:

• Pediatric SLE is a severe condition with a guarded prognosis, influenced by age of onset and specific organ involvement.
• Early recognition and aggressive management, including corticosteroids and potentially antimetabolites, are crucial for improving outcomes in childhood SLE.
• Further research into hormonal influences and novel therapeutic strategies is warranted for pediatric autoimmune diseases.
