Introduction: Systemic sclerosis (SSc) is a chronic autoimmune disease of the connective tissue marked by fibrosis, which can have different clinical forms and variations in the number of cases between populations. Objective: Analyze the clinical and epidemiological characteristics of patients, the profile of autoantibodies and mortality from SSc at the Universitary Hospital of Teresina, PI, Brazil. Methods: Review of electronic medical records, with results presented in tables of absolute and relative frequencies. The association measures were expressed in estimated values of Odds Ratio (OR). For statistical significance, p < 0.05 was considered. Results: The profile found was predominantly of brown women, over 40 years old, with an average evolution of 6 years of illness, although there was a high percentage of men in the study. Mortality was high, with a significant association with male gender, age over 60 years, age at diagnosis over 60 years, patients from the interior of the state, hospitalization for pulmonary site infection and hospitalization over 30 days. The presence of the anti-centromere autoantibody (ACA) was 30.8%, associated with limited disease and pulmonary hypertension. Antitopoisomerase I antibody (ATA) predominated in patients with diffuse cutaneous fibrosis, interstitial pneumopathy and dysphagia, with a high percentage positivity (66.7%). Conclusion: The patient profile found follows Brazilian and international data. Mortality was high, with a greater number of early deaths and infectious causes. The prevalence of anti-Slc-70 was higher than the national average, but the profiles of involvement corroborate the pattern of autoantibodies described in the literature.
