In total, 70 patients developed SRC (70\/2873, 2.4%). Of these patients, 57.1% (40\/70) were diagnosed with diffuse cutaneous SSc, 31.4% (22\/70) with limited cutaneous SSc, and 11.4% (8\/70) with SSc-overlap syndromes. Predictive independent factors with the highest probability for SRC were positive anti-RNA polymerase antibodies (RNAP), a history of proteinuria prior to SRC onset, diminished DLCO, and a history of hypertension. Interestingly, positive antitopoisomerase autoantibodies did not predict a higher risk for SRC. Further, patients with SRC were significantly more frequently treated with ACEi and corticosteroids without being independently associated with SRC.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion.<\/jats:title>\n                    <jats:p>In this cohort, SRC has become a rare complication.
