The pathophysiological features are identical with adult-onset systemic sclerosis (SSc), jSSc exhibits a distinct clinical phenotype characterized by a significantly higher prevalence of diffuse cutaneous involvement, frequent overlap syndromes, distinct autoantibody profiles, and different long-term survival trajectories. Historically, the evaluation of jSSc has relied heavily on the extrapolation of adult outcome measures, which fail to account for developmental physiology, somatic growth, and pediatric-specific feasibility constraints.</p><p><strong>Areas covered: </strong>This review provides a comprehensive overview of indicators of disease activity and severity which might be used in daily clinical practice and adapted as outcome measures in future clinical trials. It includes global outcome measures, organ-specific outcomes (including skin, pulmonary, cardiac, gastrointestinal, musculoskeletal, renal, and vascular involvement), patient-reported outcome measures (PROMs), and clinician-reported outcomes (ClinROs). The performance of adult indices within pediatric cohorts are evaluated, if applicable. Additionally, we analyze severity scores like the Juvenile Systemic Sclerosis Severity Score (J4S) alongside modern consensus metrics derived from the international Hamburg symposia. We emphasize the integration of pediatric-adapted clinical assessments, quantitative imaging, and patient and physician related outcomes.</p><p><strong>Expert opinion: </strong>The development of outcome measure in jSSc requires a paradigm shift from static severity scores to dynamic, multi-dimensional indicators capable of differentiating reversible inflammatory activity from potential permanent damage accrual.

Exome sequencing subsequently identified homozygous pathogenic variants in RNASEH2B and CYP1B1, supporting AGS type 2 and primary congenital glaucoma (glaucoma 3 A), respectively. Serial laboratory data showed sustained improvement after initiation of JAK1/2 inhibition, although the observational nature of a single case and other immunomodulatory exposures limit causal attribution.</p><p><strong>Conclusions: </strong>This case illustrates the clinical overlap between neonatal AGS and MAS-like hyperinflammation, underscores the potential role of early mechanism-based therapy in selected critically ill neonates with suspected interferonopathy, and emphasizes the importance of comprehensive genomic evaluation when severe ocular disease accompanies AGS. The identified CYP1B1 variant provides a strong molecular explanation for the patient's congenital glaucoma.</p>","PeriodicalId":54630,"journal":{"name":"Pediatric Rheumatology","volume":"24 1","pages":""},"PeriodicalIF":2.3,"publicationDate":"2026-08-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13539890/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148882527","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
