[The arguments favoring autologous haematopoietic stem cell transplantation in systemic scleroderma].

Autologous haematopoietic stem cell transplantation for systemic scleroderma, developed over more than 25 years, has shown in three randomised controlled clinical trials a significant impact not only in event-free survival, overall survival, cutaneous and pulmonary involvement, but also in the quality of life of patients living with recent severe diffuse cutaneous systemic scleroderma, compared with IV cyclophosphamid despite a transplant-related mortality between 2.4 and 10%. No immunosuppressants or biologics have shown such an impact on mortality in this disease. The risk of relapse is estimated between 9 and 24%, two years after transplant. On the basis of these results, French and international guidelines now position autologous haematopoietic stem cell transplantation as a level 1A evidence-based therapeutic alternative in severe early and rapidly progressive systemic scleroderma.
