world (469 per 100,000). The disease has some hereditary association. It may also be caused by an immune reaction to a virus (molecular mimicry) or by toxins. Society and culture Support groups The Juvenile Scleroderma Network is an organization dedicated to providing emotional support and educational information to parents and their children living with juvenile scleroderma, supporting pediatric research to identify the cause of and the cure for juvenile scleroderma, and enhancing public awareness. In the US, the Scleroderma Foundation is dedicated to raise awareness of the disease and assist those who are affected. The Scleroderma Research Foundation sponsors research into the condition. Comedian and television presenter Bob Saget, a board member of the SRF, directed the 1996 ABC TV movie For Hope, starring Dana Delany, which depicts a young woman fatally affected by scleroderma; the film was based on the experiences of Saget's sister Gay. Scleroderma and Raynaud's UK is a British charity formed by the merger of two smaller organisations in 2016 to provide support for people with scleroderma and fund research into the condition. Prognosis A 2018 study placed 10-year survival rates at 88%, without differentiation based on subtype. Diffuse systemic sclerosis, internal organ complications, and older age at diagnosis are associated with worse prognoses. Research Given the difficulty in treating scleroderma, treatments with a smaller evidence base are often tried to control the disease. These include antithymocyte globulin and mycophenolate mofetil; some reports have shown improvements in the skin symptoms, as well as delaying the progress of systemic disease, but neither has been subjected to large clinical trials. Autologous hematopoietic stem cell transplantation (HSCT) is based on the assumption that autoimmune diseases such as systemic sclerosis occur when the white blood cells of the immune system attack the body. In this treatment, stem cells from the patient's blood are extracted and stored to preserve them. The patient's white blood cells are destroyed with cyclophosphamide and rabbit antibodies against the white blood cells. Then, the stored blood is returned to the patient's bloodstream to reconstitute a healthy blood and immune system that will not attack the body. The results of a phase-III trial, the Autologous Stem Cell Transplantation International Scleroderma (ASTIS) trial, with 156 patients, were published in 2014. HSCT itself has a high treatment mortality, so in the first year, the survival of patients in the treatment group was lower than the placebo group, but at
