Abstract

Objective: To characterize the course of early scleroderma and to delineate prognostic factors present within 1 year of disease onset that might identify patients at high risk. Design: Inception cohort study. Setting: Ten university-based rheumatology clinics participating in the Cooperative Systematic Studies of Rheumatic Diseases Program. Patients: Forty-eight patients who had had scleroderma for less than 1 year. Measurements: Fifteen patients with early scleroderma who died were compared with those still living during the initial study period (1982 to 1992). Kaplan-Meier survival estimation and Cox proportional hazards analysis were used to analyze baseline variables for their ability to predict survival duration. Results: Eight of 15 deaths were due to cardiac or pulmonary system failure. The estimated 5-year survival rate was 68%. Baseline factors that were the most predictive of a poor outcome included the presence of abnormal cardiopulmonary signs and abnormal urine sediment (pyuria, hematuria). Conclusion: Evidence of early cardiopulmonary disease, renal disease, inflammation, or immune activation may identify a subset of patients with scleroderma who will experience rapidly progressive disease and early death.
