Scleroderma

Progressive systemic sclerosis; Systemic sclerosis; Limited scleroderma; CREST syndrome; Localized scleroderma; Morphea - linear; Raynaud's phenomenon - scleroderma

Scleroderma is a disease that involves the buildup of fibrous tissue in the skin and elsewhere in the body. It also damages the cells that line the walls of small arteries. This leads to tissue injury due to poor blood supply.

Causes

Scleroderma is a type of autoimmune disorder. In this condition, the immune system mistakenly attacks and damages healthy body tissue.

The cause of scleroderma is unknown. A buildup of a protein normally found in the body (called collagen) in the skin and other organs leads to the symptoms of the disease.

The disease most often affects people ages 30 to 50 years. Women get scleroderma more often than men. Some people with scleroderma have a history of being around silica dust and polyvinyl chloride, but most do not.

Widespread scleroderma can occur with other autoimmune diseases, including systemic lupus erythematosus and polymyositis. These cases are referred to as undifferentiated connective tissue disease or overlap syndrome.

Symptoms

Some types of scleroderma affect only the skin, while others affect the whole body.

  • Localized scleroderma (also called morphea) -- Often affects only the skin on the chest, abdomen, or limb but not usually on the hands and face. Morphea develops slowly, and rarely spreads in the body or causes serious problems such as internal organ damage.
  • Systemic scleroderma, or sclerosis -- May affect large areas of skin and organs such as the heart, lungs, or kidneys. There are two main types, limited disease (CREST syndrome) and diffuse disease.

Skin signs of scleroderma may include:

  • Fingers or toes that turn blue or white in response to cold temperatures (Raynaud phenomenon)
  • Stiffness and tightness of skin of fingers, hands, forearm, and face
  • Hair loss
  • Skin that is darker or lighter than normal
  • Small white lumps of calcium beneath the skin that sometimes ooze a white substance that looks like toothpaste
  • Sores (ulcers) on the fingertips or toes
  • Tight and mask-like skin on the face
  • Telangiectasias, which are small, widened blood vessels visible beneath the surface on the face or at the base of fingernails

Bone and muscle symptoms may include:

  • Joint pain, stiffness, and swelling, resulting in loss of motion. The hands are often involved due to fibrosis around tissue and tendons.
  • Numbness and pain in the feet.

Breathing problems may result from scarring in the lungs and can include:

  • Dry cough
  • Shortness of breath
  • Wheezing
  • Increased risk for lung cancer

Digestive tract problems may include:

Heart problems may include:

  • Abnormal heart rhythm
  • Fluid around the heart
  • Fibrosis in heart muscle, decreasing heart function

Kidney and genitourinary problems may include:

Exams and Tests

The health care provider will do a complete physical exam. The exam may show:

  • Tight, thick skin on the fingers, the face or elsewhere.
  • The skin at the base of the fingernails may be looked at with a lighted magnifying glass for abnormalities of the small blood vessels.
  • The lungs, heart and abdomen will be examined for abnormalities.

Your blood pressure will be checked. Scleroderma can cause small blood vessels in the kidneys to become narrowed. Problems with your kidneys can lead to high blood pressure and decrease function of the kidney.

Blood and urine tests may include:

Other tests may include:

Treatment

There is no specific treatment for scleroderma. Your provider will assess the extent of disease in the skin, lungs, kidneys, heart, and gastrointestinal tract.

People with diffuse skin disease (rather than limited skin involvement) may be more prone to progressive and internal organ disease. This form of the disease is classified as diffuse cutaneous systemic sclerosis (dcSSc). Body wide (systemic) treatments are most often used for this group of patients.

You will be prescribed medicines and other treatments to control your symptoms and prevent complications.

Medicines used to treat progressive scleroderma include:

  • Corticosteroids such as prednisone. However, doses above 10 mg per day are not recommended because higher doses may trigger kidney disease and high blood pressure.
  • Medicines that suppress the immune system such as mycophenolate, cyclophosphamide, cyclosporine or methotrexate.
  • Hydroxychloroquine to treat arthritis.

Some people with rapidly progressive scleroderma may be candidates for autologous hematopoietic stem cell transplantation (HSCT). This type of treatment needs to be performed in specialized centers.

Other treatments for specific symptoms may include:

  • Treatments to improve Raynaud phenomenon.
  • Medicines for heartburn or swallowing problems, such as omeprazole.
  • Blood pressure medicines, such as ACE inhibitors, for high blood pressure or kidney problems.
  • Light therapy to relieve skin thickening.
  • Medicines to improve lung function, such as bosentan and sildenafil.

Treatment often involves physical therapy as well.

Support Groups

Some people can benefit from attending a support group for people with scleroderma.

Outlook (Prognosis)

In some people, symptoms develop quickly for the first few years and continue to get worse. However, in most people, the disease gets worse only slowly.

People who have only skin symptoms have a better outlook. Widespread (systemic) scleroderma can lead to.

  • Heart failure
  • Scarring of the lungs, called pulmonary fibrosis
  • High blood pressure in the lungs (pulmonary hypertension)
  • Kidney failure (scleroderma renal crisis)
  • Problems absorbing nutrients from food
  • Cancer

When to Contact a Medical Professional

Contact your provider if you develop Raynaud phenomenon, progressive thickening of the skin, or trouble swallowing.

  • Raynaud's phenomenon

    Raynaud's phenomenon - illustration

    Raynaud's phenomenon is characterized by blood vessel spasms in the fingers, toes, ears or nose, usually brought on by exposure to cold. Raynaud's phenomenon and Raynaud's disease, a similar disorder, may be associated with autoimmune disorders such as rheumatoid arthritis, systemic lupus erythematosus and scleroderma.

  • CREST syndrome

    CREST syndrome - illustration

    The symptoms involved in CREST syndrome are associated with the generalized form of the disease Systemic sclerosis, scleroderma. CREST is an acronym for the clinical features that are seen in a patient with this disease. The C stands for calcinosis, where calcium deposits form under the skin on the fingers or other areas of the body. The R stands for Raynaud's phenomenon, spasm of blood vessels in the fingers or toes in response to cold or stress. The E represents esophageal dysmotility, which can cause difficulty in swallowing. The S is for sclerodactyly, tightening of the skin causing the fingers to bend. Finally, the letter T is for telangiectasia, dilated vessels on the skin of the fingers, face, or inside of the mouth. Usually only 2 of the 5 symptoms of the CREST syndrome is necessary to be diagnosed with the disease.

  • Sclerodactyly

    Sclerodactyly - illustration

    The most classic symptom of scleroderma is a type of skin tightening called sclerodactyly. The initial stages of the disease involves swelling of the fingers. Later, as the connective tissue becomes fibrotic, skin on the fingers and toes becomes hard and shiny. The fingers can become difficult to bend and can form contractures due to the severe tightening of the skin.

  • Telangiectasia

    Telangiectasia - illustration

    Telangiectasia is the dilation of small superficial vessels and capillaries that cause numerous flat red marks on the hands, face and tongue. Telangiectasia can be a symptom of scleroderma or other systemic diseases.
