Answer

Systemic sclerosis has the highest case-specific mortality among the systemic autoimmune diseases. Pulmonary hypertension, pulmonary fibrosis (interstitial lung disease), and scleroderma renal crisis are the most frequent causes of mortality. [32, 33, 34, 35, 36, 37, 38, 39]

Survival has improved in recent decades and correlates best with the clinical disease subtype (diffuse cutaneous vs limited cutaneous) and with the extent of organ involvement. Five-year survival among patients with diffuse cutaneous systemic sclerosis has improved significantly, from 69% in the 1990–1993 cohort to 84% in the 2000–2003 cohort. Five-year survival among the patients with limited cutaneous systemic sclerosis remained very high and unchanged for the same periods (93% and 91%, respectively).

Mortality associated with scleroderma renal crisis has declined significantly during the last decades, as use of angiotensin-converting enzyme (ACE) inhibitors. In contrast, pulmonary involvement (interstitial lung disease and/or pulmonary arterial hypertension) has become the most common cause of death in patients with systemic sclerosis.
