Commonly asked questions about Scleroderma

What is Scleroderma?

Scleroderma is a set of rare diseases that involve the hardening and tightening of skin and other connective tissues. Scleroderma only affects the skin in some patients, however, in many others scleroderma also affects blood vessels, internal organs and the digestive tract.

What Causes Scleroderma?

According to the Mayo Clinic, scleroderma is the result from your body’s overproduction and storage of collagen in body tissues. Collagen is the protein that makes up your body’s skin and other connective tissues. Doctors are unsure of what actually triggers the abnormal collagen production. They only know that the body’s immune system is a factor.

What Risk Factors are Associated with Scleroderma?

Medical News Today states that doctors are unsure of what exactly causes scleroderma. However, they do know that scleroderma is about four times more likely to occur in women than in men. If a person has a family member that has another form of autoimmune disease they may be at an increased risk of developing scleroderma.

What are the Different Types of Scleroderma?

The Scleroderma Foundation states that scleroderma falls into two major classifications known as localized scleroderma and systemic sclerosis.

  • Localized Scleroderma: The mildest form of scleroderma, it does not affect the internal organs. Localized scleroderma can be broken down into two smaller sub-categories known as Morphea and Linear Scleroderma.
    • Morphea: Oval-shaped patches of lighter or darker skin, which may be itchy, hairless and shiny. The shapes have a purple border and are white in the middle.
    • Linear Scleroderma: People that are diagnosed with linear may have bands or streaks of hardened skin on the head, face and limbs. It is also able to affect bones and muscles.
  • Systemic Sclerosis: Affects the circulation of blood and the internal organs, especially the kidneys, esophagus, heart and lungs. There are also two smaller sub-categories of systemic scleroderma known as Limited and Diffuse.
    • Limited: Is the least severe type of systemic scleroderma. It affects the skin on the hands, feet, face, and lower arms and legs. There may be problems with the lungs and the digestive system.
    • Diffuse: Skin thickening occurs more rapidly than in limited as well as involving more skin areas. People affected by diffuse scleroderma also have a higher risk of the hardening of internal organs.

What are the Signs/Symptoms/Complications of Scleroderma?

The Mayo Clinic provides a list of the most common signs and symptoms of scleroderma, these include:

SkinMost people with scleroderma experience a hardening and tightening of skin patches. Patches may be shaped like ovals or straight lines, or cover wide areas. The type of scleroderma determines the number, location and size of the patches.
Fingers or ToesOne of the first signs of scleroderma is an intolerance of cold temperatures or exaggerated emotional distress, which can cause numbness, pain or color changes in the fingers or toes.
Digestive SystemIf your intestinal muscles are having a hard time moving food properly through the intestines, you may have problems absorbing key nutrients.
Heart, Lungs or KidneysScleroderma has the ability to affect the function of the heart, lungs or kidneys to varying degrees. If left untreated, these issues may become life-threatening.

The Mayo Clinic also lists a number of severe complications that may occur alongside normal scleroderma symptoms, such as:

FingertipsThe hardening and tightening of skin patches that occurs can be so severe that the restricted blood flow permanently damages the tissue at the fingertips, causing pits or skin sores. In some cases, gangrene and amputation may follow.
LungsScarring of lung tissue can result in a decrease of the lungs’ ability to function as well as difficulty breathing and reduced tolerance for exercise. You may also develop high blood pressure in the arteries to your lungs.
KidneysIf scleroderma affects your kidneys, you may develop elevated blood pressure as well as an increased level of protein in your urine. The more-serious effect of kidney complications may include renal crisis, which involves a sudden increase in blood pressure and rapid kidney failure.
HeartScarring of heart tissue increases your risk of developing an arrhythmia or congestive heart failure, and can cause inflammation of the sac surrounding your heart. Scleroderma can also cause your heart to wear out by increasing the pressure on the right side.
TeethSevere tightening of facial skin can cause your mouth to become smaller and narrower, which may make it difficult to brush your teeth or to even have a dentist clean them. People who have scleroderma often don’t produce normal amounts of saliva, so the risk of dental decay increases even more.
Digestive SystemDigestive problems linked with scleroderma may lead to acid reflux and difficulty swallowing.
Sexual FunctionMen who have scleroderma often experience erectile dysfunction. Scleroderma may also affect women, by decreasing sexual lubrication and constricting the vaginal opening.

Is Scleroderma Curable?

Currently there is no cure available for scleroderma. Even though there is not a cure for scleroderma the Scleroderma Foundation says that there are a number of available treatments to assist people with the varying symptoms that they may have.

What Drugs/Medicines are used to Treat Scleroderma?

Below you will find a list of drugs that are used to help treat scleroderma. Due to there being such a wide variety of symptoms and severity of this condition there is no one specific medicine that is used to treat scleroderma. The Scleroderma Research Foundation lists the possible drug groups. They include:
