To establish a new prospective cohort of Korean patients with systemic sclerosis and track the natural history of the disease over time.
To generate new hypotheses for further investigation.
Systemic sclerosis (SSc) is a multisystem and heterogeneous disease characterized by an unpredictable course and high morbidity and mortality. The complexity of SSc requires interdisciplinary diagnostic and therapeutic management and result in a growing burden for all health-care systems. For this reasons, researchers are seeking new diagnostic and therapeutic strategies to improve management of these patients. In order to improve clinical care and to develop recommendations for the diagnosis and treatment of SSc, disease registries are used to capture and track key patient information.
Therefore, SSc research associations and consortiums play a pivotal role to perform ongoing research and data collection to understanding the disease and support research projects. Currently, several national SSc registries in the UK, Germany, USA, Canada, Brazil, Australia and international registry, EUSTAR (European League Against Rheumatism scleroderma trial and research), have been established. However, the natural history of Asian populations are fully evaluated. Therefore, investigators decided to establish SSc cohort in Korean patients.

| This is an observational prospective study. | Other | Investigators will get clinical information including gender, date of birth, height, weight, family history for systemic sclerosis, education, and symptoms of organ involvement of skin, lung, heart, gastrointestinal tract, kidney, musculoskeletal system and laboratory data. Investigators will evaluate nailbed capillary microscope, hand x-ray, 6 minute walk test, echocardiography, computed tomography of chest, pulmonary function test (FVC%, DLCO%), and electrocardiogram as baseline. Investigators permit replacement of previous results within one year from baseline. Participants in the cohort will be followed up annually and investigators will treat SSc patients according to their routine practice in the best interest of patents. Medications for other comorbid conditions are allowed. |
| Measure | Description | Time Frame |
|---|---|---|
| Internal organ involvement | Number of participants with internal organ involvement (Interstitial lung disease, Pulmonary arterial hypertension, Cardiac involvement, Gastrointestinal involvement, Renal involvement) | 2-year |
| Measure | Description | Time Frame |
|---|---|---|
| Interstitial lung disease | Number of participants with ILD (at baseline and and during follow up) by computed tomography of chest | 2-year |
| Interstitial lung disease-progression | Number of participants with progression of ILD from baseline by computed tomography of chest |
