Prognosis:

At this time there is no cure for scleroderma and no treatment to change its course, but outlook varies widely. Many patients, even those with systemic scleroderma, can expect a normal lifespan.

General Outlook of Localized Scleroderma. Localized scleroderma nearly always carries a good prognosis and a normal life span. Even localized scleroderma, however, can cause some severe effects in children, including impaired growth, limb imbalance, and problems in flexing and bending muscles.

General Outlook of Systemic Scleroderma. The outlook for patients with systemic scleroderma has generally improved over the years. Ten-year survival rates rose from 54% in 1972 to 66% in 2001.

The causes of death related to systemic scleroderma also have changed. The proportion of deaths from kidney crises has dropped significantly, while the proportion of deaths from pulmonary fibrosis has increased. Today, lung complications account for 60% of scleroderma-related deaths.

• Limited Scleroderma. Patients with limited CREST scleroderma can usually expect a favorable outlook and normal lifespan if the disease affects only the hands and face. The course of this type of scleroderma still tends to be slowly progressive and, in some cases, may affect internal organs.
• Diffuse Scleroderma. The severity of diffuse scleroderma varies widely, and it is very difficult to predict its course. It generally follows one of two paths: If it is acute or rapidly progressing, it may be a life-threatening condition that affects internal organs. The most critical period for rapid progression is usually within the first 2 - 5 years of the start of the disease. In the absence of rapid progression, or if the patient survives the initial acute progression, the disease tends to progress very slowly. The more severe the condition of the skin is at the start of the disease, the poorer the survival rates.

Many patients with systemic scleroderma experience a plateau in which the condition stabilizes. This plateau is followed by a period of improvement and skin softening. No one knows why this occurs, and it can happen regardless of treatment. In one study, patients with systemic scleroderma who experienced such improvements also had better survival rates (80% at 10 years) than those whose skin did not improve (60% 10-year survival rate).

Impact on Quality of Life

The many complications of scleroderma can have a major impact on a person's sense of well-being. Patients are greatly concerned about changes in their appearance, particularly those changes caused by tightening of the facial skin. Depression has great impact, along with pain, on reducing patients' ability to function socially.
