Factors affecting survival in juvenile systemic sclerosis.

Area of Science:

• Pediatric Rheumatology
• Immunodermatology
• Systemic Autoimmune Diseases

Background:

• Juvenile Systemic Sclerosis (JSSc) is a rare autoimmune condition affecting children.
• Understanding predictors of outcome is crucial for early intervention and improved patient management.

Purpose of the Study:

• To identify demographic, clinical, and immunological factors that predict mortality in pediatric patients with Systemic Sclerosis.

Main Methods:

• Analysis of clinical and laboratory data from 134 JSSc patients across 40 international pediatric rheumatology centers.
• Univariate and multivariate logistic regression analyses were employed to determine mortality predictors.

Main Results:

• Sixteen patients (11.9%) died, most with rapidly fatal courses within 5 years of diagnosis.
• Early internal organ involvement (cardiac, respiratory, gastrointestinal) was significantly associated with poor outcomes.
• Multivariate analysis identified chest X-ray fibrosis (OR 11.2), elevated creatinine (OR 22.7), and pericarditis (OR 41.3) as mortality predictors; shorter disease duration was protective (OR 0.3).

Conclusions:

• Fatal JSSc cases were predominantly diffuse, characterized by rapid progression and early organ involvement.
• Pediatric Scleroderma may present with two distinct clinical courses: a rapidly progressive, fatal form with organ failure, or a slower course with lower mortality.
