Background: SSc has a high morbidity and mortality, therefore it is important to detect the disease at an early stage. Very early detection of SSc allows early management, which has been shown to profoundly impact on the disease course in different inflammatory rheumatic diseases. However, patients fulfilling criteria for the diagnosis of very early SSc could also be patients with a very mild, very slowly progressing, long-standing disease. Objectives: To identify a subgroup of patients with long-standing, very mild SSc among the patients fulfilling the criteria for the very early diagnosis of SSc by analyzing clinical, epidemiological and immunological characteristics of the Zurich patient cohort. Methods: Baseline data of the SSc patients from the University Hospital of Zurich cohort are analyzed in this study. Demographic and disease characteristics of the patients enrolled between January 2009 and June 2018 into the Very Early Diagnosis of Systemic Sclerosis (VEDOSS) cohort were analyzed. Patients fulfilling the aCR/EULAR2013 criteria and patients with primary Raynaud phenomenon were excluded. Disease duration was calculated as the difference between the baseline visit date and the date of the first Raynaud’s phenomenon (RP) symptom reported by the patient. For further analysis, the cohort was divided into two subgroups using a cut off value of Results: A total of 107 patients met the inclusion criteria. The patients’ demographic and disease characteristics are shown in Table 1 and Table 2. The majority of patients had a short disease duration measured from first Raynaud attack of Conclusion: This analysis is showing that patients fulfilling VEDOSS criteria include a subgroup of patients with very mild, long-standing disease. This observation has major impact on the management of VEDOSS patients, as this subgroup requires different follow up and treatment strategies compared to VEDOSS patients with early, progressive disease.
