Background:
Juvenile systemic sclerosis (jSSc) can lead to permanent and irreversible anatomical or physiological dysfunction. The Scleroderma Clinical Trials Consortium-Damage Index (SCTC-DI), which has been employed and validated in adult patients, can quantify organ damage and predict mortality and morbidity. However, its application in paediatric patients remains unexplored.
Methods:
Clinical data, laboratory results, and prognostic information were collected for patients with jSSc at Peking Union Medical College Hospital (PUMCH) from January 2012 and January 2024. Differences between the SCTC-DI and the juvenile systemic sclerosis severity score (J4S) were recorded and compared. Furthermore, we compared the SCTC-DI between jSSc and adult systemic sclerosis (SSc) patients.
Results:
A total of 64 jSSc patients were included. Facet joint contractures, fingertip ulcers and interstitial lung disease are common manifestations. Compared with adult SSc patients, jSSc patients had a lower incidence of gastrointestinal and urinary system involvement. The baseline J4S levels were significantly correlated with SCTC-DI levels at follow-up. A higher baseline SCTC-DI score was associated with a greater progression of organ damage (P = 0.001).
Conclusion:
There are differences in clinical presentations between adult SSc patients and jSSc patients. The SCTC-DI can be applied to JSSc patients, and it is recommended that JSSc patients undergo regular evaluations of the J4S as well as the SCTC-DI.
