Handout on Health: Scleroderma
This booklet is for people who have scleroderma, as well as for their family members, friends, and others who want to find out more about the disease. This booklet describes the different forms of scleroderma and provides information on their symptoms, diagnosis, and treatment, including what patients can do to help manage their disease and the problems associated with it. This booklet also highlights research efforts into the understanding and treatment of scleroderma, many of which are supported by the National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS) and other components of the U.S. Department of Health and Human Services’ National Institutes of Health (NIH). If you have further questions after reading this booklet, you may wish to discuss them with your doctor.
Derived from the Greek words “sklerosis,” meaning hardness, and “derma,” meaning skin, scleroderma literally means “hard skin.” Although it is often referred to as if it were a single disease, scleroderma is really a symptom of a group of diseases that involve the abnormal growth of connective tissue, which supports the skin and internal organs. It is sometimes used, therefore, as an umbrella term for these disorders. In some forms of scleroderma, hard, tight skin is the extent of this abnormal process. In other forms, however, the problem goes much deeper, affecting blood vessels and internal organs, such as the heart, lungs, and kidneys.
Scleroderma is called both a rheumatic (roo-MA-tik) disease and a connective tissue disease. The term rheumatic disease refers to a group of conditions characterized by inflammation or pain in the muscles, joints, or fibrous tissue. A connective tissue disease is one that affects tissues such as skin, tendons, and cartilage.
In this booklet we’ll discuss the forms of scleroderma and the problems associated with each of them, as well as diagnosis and disease management. We’ll also take a look at what research is telling us about their possible causes and most effective treatments. And we will describe ways for people with scleroderma to live longer, healthier, and more productive lives.
The group of diseases we call scleroderma falls into two main classes: localized scleroderma and systemic sclerosis. (Localized diseases affect only certain parts of the body; systemic diseases can affect the whole body.) Both groups include subgroups (see chart). Although there are different ways these groups and subgroups may be broken down or referred to (and your doctor may use different terms from what you see here), the following is a common way of classifying these diseases:
Types of Scleroderma
Localized types of scleroderma are those limited to the skin and related tissues and, in some cases, the muscle below. Internal organs are not affected by localized scleroderma, and localized scleroderma can never progress to the systemic form of the disease. Often, localized conditions improve or go away on their own over time, but the skin changes and damage that occur when the disease is active can be permanent. For some people, localized scleroderma is serious and disabling.
There are two generally recognized types of localized scleroderma:
Morphea: Morphea (mor-FEE-ah) comes from a Greek word that means “form” or “structure.” The word refers to local patches of scleroderma. The first signs of the disease are reddish patches of skin that thicken into firm, oval-shaped areas. The center of each patch becomes ivory colored with violet borders. These patches sweat very little and have little hair growth. Patches appear most often on the chest, stomach, and back. Sometimes they appear on the face, arms, and legs.
Morphea can be either localized or generalized. Localized morphea limits itself to one or several patches, ranging in size from a half-inch to 12 inches in diameter. The condition sometimes appears on areas treated by radiation therapy. Some people have both morphea and linear scleroderma (described below). The disease is referred to as generalized morphea when the skin patches become very hard and dark and spread over larger areas of the body. Regardless of the type, morphea generally fades out in 3 to 5 years; however, people are often left with darkened skin patches and, in rare cases, muscle weakness.
Linear scleroderma: As suggested by its name, the disease is characterized by a single line or band of thickened or abnormally colored skin. Usually, the line runs down an arm or leg, but in some people it runs down the forehead. People sometimes use the French term en coup de sabre, or “sword stroke,” to describe this highly visible line.
Systemic Scleroderma (also known as Systemic Sclerosis)
This is the term for the form of the disease that not only includes the skin, but also involves the tissues beneath, the blood vessels, and the major organs. Systemic sclerosis is typically broken down into limited cutaneous scleroderma and diffuse cutaneous scleroderma. Some doctors break systemic sclerosis down into a third subset called systemic sclerosis sine (SEEN-ay, Latin for “without”) scleroderma. This means that patients have other manifestations of scleroderma but they do not have any overt skin thickening.
Limited cutaneous scleroderma: Limited cutaneous scleroderma typically comes on gradually and affects the skin only in certain areas: the fingers, hands, face, lower arms, and legs. Most people with limited disease have Raynaud’s phenomenon for years before skin thickening starts. Telangiectasia and calcinosis often follow (see definitions below). Gastrointestinal involvement occurs commonly, and some patients have severe lung problems, even though the skin thickening remains limited. People with limited disease often have all or some of the symptoms that some doctors call CREST, which stands for the following:
- Calcinosis (KAL-sin-OH-sis): The formation of calcium deposits in the connective tissues, which can be detected by x ray. These deposits are typically found on the fingers, hands, face, and trunk and on the skin above elbows and knees. When the deposits break through the skin, painful ulcers can result.
- Raynaud’s (ray-NOHZ) phenomenon: A condition in which the small blood vessels of the hands or feet contract in response to cold or anxiety. As the vessels contract, the hands or feet turn white and cold, then blue. As blood flow returns, they become red. Fingertip tissues may suffer damage, leading to ulcers, scars, or gangrene.
- Esophageal (eh-SOFF-uh-GEE-ul) dysfunction: Impaired function of the esophagus (the tube connecting the throat and the stomach) that occurs when smooth muscles in the esophagus lose normal movement. In the upper and lower esophagus, the result can be swallowing difficulties. In the lower esophagus, the result can be chronic heartburn or inflammation.
- Sclerodactyly (SKLER-oh-DAK-till-ee): Thick and tight skin on the fingers, resulting from deposits of excess collagen within skin layers. The condition makes it harder to bend or straighten the fingers. The skin may also appear shiny and darkened, with hair loss.
- Telangiectasia (tel-AN-jee-ek-TAY-zee-uh): A condition caused by the swelling of tiny blood vessels, in which small red spots appear on the hands and face. Although not painful, these red spots can create cosmetic problems.
Diffuse cutaneous scleroderma: This condition typically comes on suddenly. Skin thickening begins in the hands and spreads quickly and over much of the body, affecting the hands, face, upper arms, upper legs, chest, and stomach in a symmetrical fashion (for example, if one arm or one side of the trunk is affected, the other is also affected). Some people may have more area of their skin affected than others. Internally, this condition can damage key organs such as the intestines, lungs, heart, and kidneys.
People with diffuse disease often are tired, lose appetite and weight, and have joint swelling or pain. Skin changes can cause the skin to swell, appear shiny, and feel tight and itchy.
The damage of diffuse scleroderma typically occurs over a few years. After the first 3 to 5 years, people with diffuse disease often enter a stable phase lasting for varying lengths of time. During this phase, symptoms subside: joint pain eases, fatigue lessens, and appetite returns. Progressive skin thickening and organ damage decrease.
Gradually, however, the skin may begin to soften, which tends to occur in reverse order of the thickening process: the last areas thickened are the first to begin softening. Some patients’ skin returns to a somewhat normal state, while other patients are left with thin, fragile skin without hair or sweat glands. Serious new damage to the heart, lungs, or kidneys is unlikely to occur, although patients are left with whatever damage they have in specific organs.
People with diffuse scleroderma face the most serious long-term outlook if they develop severe kidney, lung, digestive, or heart problems. Fortunately, less than one-third of patients with diffuse disease develop these severe problems. Early diagnosis and continual and careful monitoring are important.
Although scientists don’t know exactly what causes scleroderma, they are certain that people cannot catch it from or transmit it to others. Studies of twins suggest it is also not inherited. Scientists suspect that scleroderma comes from several factors that may include:
Abnormal immune or inflammatory activity: Like many other rheumatic disorders, scleroderma is believed to be an autoimmune disease. An autoimmune disease is one in which the immune system, for unknown reasons, turns against one’s own body.
In scleroderma, the immune system is thought to stimulate cells called fibroblasts so they produce too much collagen. The collagen forms thick connective tissue that builds up within the skin and internal organs and can interfere with their functioning. Blood vessels and joints can also be affected.
Genetic makeup: Although genes seem to put certain people at risk for scleroderma and play a role in its course, the disease is not passed from parent to child like some genetic diseases.
Environmental triggers: Research suggests that exposure to some environmental factors may trigger scleroderma-like disease (which is not actually scleroderma) in people who are genetically predisposed to it. Suspected triggers include viral infections, certain adhesive and coating materials, and organic solvents such as vinyl chloride or trichloroethylene. But no environmental agent has been shown to cause scleroderma. In the past, some people believed that silicone breast implants might have been a factor in developing connective tissue diseases such as scleroderma. But several studies have not shown evidence of a connection.
Hormones: Women develop scleroderma more often than men. Scientists suspect that hormonal differences between women and men play a part in the disease. However, the role of estrogen or other female hormones has not been proven.
Although scleroderma is more common in women, the disease also occurs in men and children. It affects people of all races and ethnic groups. However, there are some patterns by disease type. For example:
- Localized forms of scleroderma are more common in people of European descent than in African Americans. Morphea usually appears between the ages of 20 and 40, and linear scleroderma usually occurs in children or teenagers.
- Systemic scleroderma, whether limited or diffuse, typically occurs in people from 30 to 50 years old. It affects more women of African American than European descent.
Because scleroderma can be hard to diagnose and it overlaps with or resembles other diseases, scientists can only estimate how many cases there actually are. It is estimated that 49,000 adults in the United States have systemic sclerosis.1
1Helmick CG, Felson DT, Lawrence RC, Gabriel S, Hirsch R, Kwoh CK, Liang MH, Kremers M, Mayes MD, Merkel PA, Pillemer SR, Reveille JD, Stone JH; National Arthritis Data Workgroup. Estimates of the prevalence of arthritis and other rheumatic conditions in the United States. Part I. Arthritis Rheum. 2008 Jan;58(1):15-25.
For some people, scleroderma (particularly the localized forms) is fairly mild and resolves with time. But for others, living with the disease and its effects day to day has a significant impact on their quality of life.
Depending on your particular symptoms, a diagnosis of scleroderma may be made by:
- A general internist.
- A dermatologist (a doctor who specializes in treating diseases of the skin, hair, and nails).
- An orthopaedist (a doctor who treats bone and joint disorders).
- A pulmonologist (a lung specialist).
- A rheumatologist (a doctor specializing in treatment of musculoskeletal disorders and rheumatic diseases).
A diagnosis of scleroderma is based largely on the medical history and findings from the physical exam. To make a diagnosis, your doctor will ask you a lot of questions about what has happened to you over time and about any symptoms you may be experiencing. Are you having a problem with heartburn or swallowing? Are you often tired or achy? Do your hands turn white in response to anxiety or cold temperatures?
Once your doctor has taken a thorough medical history, he or she will perform a physical exam. Finding one or more of the following factors can help the doctor diagnose a certain form of scleroderma:
- changed skin appearance and texture, including swollen fingers and hands and tight skin around the hands, face, mouth, or elsewhere
- calcium deposits developing under the skin
- changes in the tiny blood vessels (capillaries) at the base of the fingernails
- thickened skin patches.
Finally, your doctor may order lab tests to help confirm a suspected diagnosis. At least two proteins, called antibodies, are commonly found in the blood of people with scleroderma:
- Antitopoisomerase-1 or Anti-Scl-70 antibodies appear in the blood of up to 30 percent of people with diffuse systemic sclerosis.
- Anticentromere antibodies are found in the blood of many people with limited systemic sclerosis.
A number of other scleroderma-specific antibodies can occur in people with scleroderma, although less frequently. When present, however, they are helpful in clinical diagnosis and may give additional information as to the risks for specific organ problems.
Because not all people with scleroderma have these antibodies and because not all people with the antibodies have scleroderma, lab test results alone cannot confirm the diagnosis.
In some cases, your doctor may order a skin biopsy (the surgical removal of a small sample of skin for microscopic examination) to aid in or help confirm a diagnosis. However, skin biopsies also have their limitations: biopsy results cannot distinguish between localized and systemic disease, for example.
Diagnosing scleroderma is easiest when a person has typical symptoms and rapid skin thickening. In other cases, a diagnosis may take months, or even years, as the disease unfolds and reveals itself and as the doctor is able to rule out some other potential causes of the symptoms. In some cases, a diagnosis is never made, because the symptoms that prompted the visit to the doctor go away on their own.
Some patients have some symptoms related to scleroderma and may fit into one of the following groups:
- Undifferentiated connective tissue disease (UCTD): This is a term for patients who have some signs and symptoms of various related diseases, but not enough symptoms of any one disease to make a definitive diagnosis. In other words, their condition hasn’t “differentiated” into a particular connective tissue disease. In time, UCTD can go in one of three directions: it can change into a systemic disease such as systemic sclerosis, systemic lupus erythematosus, or rheumatoid arthritis; it can remain undifferentiated; or it can improve spontaneously.
- Overlap syndromes: This is a disease combination in which patients have symptoms and lab findings characteristic of two or more conditions.
A number of other diseases have symptoms similar to those seen in scleroderma. Here are some of the most common scleroderma “look-alikes.”
Eosinophilic fasciitis (EF) (EE-oh-SIN-oh-FIL-ik fa-shi-EYE-tis): This disease involves the fascia (FA-shuh), the thin connective tissue around the muscles, particularly those of the forearms, arms, legs, and trunk. EF causes the muscles to become encased in collagen, the fibrous protein that makes up tissue such as the skin and tendons. Permanent shortening of the muscles and tendons, called contractures, may develop, sometimes causing disfigurement and problems with joint motion and function. EF may begin after hard physical exertion. The disease usually fades away after several years, but people sometimes have relapses. Although the upper layers of the skin are not thickened in EF, the thickened fascia may cause the skin to look somewhat like the tight, hard skin of scleroderma. A skin biopsy easily distinguishes between the two diseases.
Skin thickening on the fingers and hands: This also appears with diabetes, mycosis fungoides, amyloidosis, and adult celiac disease. It can also result from hand trauma.
Generalized scleroderma-like skin thickening: This may occur with scleromyxedema, graft-versus-host disease, porphyria cutanea tarda, and human adjuvant disease.
Internal organ damage: Similar to that seen in systemic sclerosis, this may instead be related to primary pulmonary hypertension, idiopathic pulmonary fibrosis, or collagenous colitis.
Raynaud’s phenomenon: This condition also appears with atherosclerosis or systemic lupus erythematosus or in the absence of underlying disease.
An explanation of most of these other diseases is beyond the scope of this booklet. What’s important to understand, however, is that diagnosing scleroderma isn’t always easy, and it may take time for you and your doctor to do this. Although having a definite diagnosis may be helpful, you do not need to know the precise form of your disease to receive proper treatment.
Because scleroderma can affect many different organs and organ systems, you may have several different doctors involved in your care. Typically, care will be managed by a rheumatologist (a doctor specializing in treatment of musculoskeletal disorders and rheumatic diseases). Your rheumatologist may refer you to other specialists, depending on the specific problems you are having. For example, you may see a dermatologist for the treatment of skin symptoms, a nephrologist for kidney complications, a cardiologist for heart complications, a gastroenterologist for problems of the digestive tract, and a pulmonary specialist for lung involvement.
In addition to doctors, professionals such as nurse practitioners, physician assistants, physical or occupational therapists, psychologists, and social workers may play a role in your care. Dentists, orthodontists, and even speech therapists can treat oral complications that arise from thickening of tissues in and around the mouth and on the face.
Currently, there is no treatment that controls or stops the underlying problem—the overproduction of collagen—in all forms of scleroderma. Thus, treatment and management focus on relieving symptoms and limiting damage. Your treatment will depend on the particular problems you are having. Some treatments will be prescribed or given by your doctor. Others are things you can do on your own.
Here is a listing of the potential problems that can occur in systemic scleroderma and the medical and nonmedical treatments for them. These problems do not occur as a result or complication of localized scleroderma. This listing is not complete because different people experience different problems with scleroderma and not all treatments work equally well for all people. Work with your doctor to find the best treatment for your specific symptoms.
Raynaud’s phenomenon: Most people with scleroderma have this condition, in which the fingers and sometimes other extremities change color in response to cold temperature or anxiety. For many, Raynaud’s phenomenon precedes other manifestations of the disease. In other people, however, Raynaud’s phenomenon is unrelated to scleroderma, but may signal damage to the blood vessels supplying the hands arising from occupational injuries (from using jackhammers, for example), trauma, excessive smoking, circulatory problems, drug use, or exposure to toxic substances. For some people, cold fingers and toes are the extent of the problem and are little more than a nuisance. For others, the condition can worsen and lead to puffy fingers, finger ulcers, and other complications that require aggressive treatment.
If you have Raynaud’s phenomenon, the following measures may make you more comfortable and help prevent problems:
- Don’t smoke! Smoking narrows the blood vessels even more and makes Raynaud’s phenomenon worse.
- Dress warmly, with special attention to hands and feet. Dress in layers and try to stay indoors during cold weather.
- Use biofeedback, which governs various body processes that are not normally thought of as being under conscious control, and relaxation exercises.
- For severe cases, speak to your doctor about prescribing drugs called calcium channel blockers, which can open up small blood vessels and improve circulation. Other drugs are in development and may become available.
- If Raynaud’s phenomenon leads to skin sores or ulcers, increasing your dose of calcium channel blockers (ONLY under the direction of your doctor) may help. You can also protect skin ulcers from further injury or infection by applying nitroglycerine paste or antibiotic cream. Severe ulcerations on the fingertips can be treated with bioengineered skin.
Stiff, painful joints: In diffuse systemic sclerosis, hand joints can stiffen because of hardened skin around the joints or inflammation within them. Other joints can also become stiff and swollen.
- Stretching exercises under the direction of a physical or occupational therapist are extremely important to prevent loss of joint motion. These should be started as soon as scleroderma is diagnosed.
- Exercise regularly. Ask your doctor or physical therapist about an exercise plan that will help you increase and maintain range of motion in affected joints. Swimming can help maintain muscle strength, flexibility, and joint mobility.
- Use acetaminophen or an over-the-counter or prescription nonsteroidal anti-inflammatory drug, as recommended by your doctor, to help relieve joint or muscle pain. If pain is severe, speak to a rheumatologist about the possibility of prescription-strength drugs to ease pain and inflammation.
- Learn to do things in a new way. A physical or occupational therapist can help you learn to perform daily tasks, such as lifting and carrying objects or opening doors, in ways that will put less stress on tender joints.
Skin problems: When too much collagen builds up in the skin, it crowds out sweat and oil glands, causing the skin to become dry and stiff. If your skin is affected, try the following:
- Apply oil-based creams and lotions frequently, and always right after bathing.
- Apply sunscreen before you venture outdoors to protect against further damage from the sun’s rays.
- Use humidifiers to moisten the air in your home in colder winter climates. Clean humidifiers often to stop bacteria from growing in the water.
- Avoid very hot baths and showers, as hot water dries the skin.
- Avoid harsh soaps, household cleaners, and caustic chemicals, if at all possible. Otherwise, be sure to wear rubber gloves when you use such products.
- Exercise regularly. Exercise, especially swimming, stimulates blood circulation to affected areas.
Dry mouth and dental problems: Dental problems are common in people with scleroderma for a number of reasons:
- Tightening facial skin can make the mouth opening smaller and narrower, which makes it hard to care for teeth.
- Dry mouth caused by salivary gland damage speeds up tooth decay.
- Damage to connective tissues in the mouth can lead to loose teeth.
You can avoid tooth and gum problems in several ways:
- Brush and floss your teeth regularly. If hand pain and stiffness make this difficult, consult your doctor or an occupational therapist about specially made toothbrush handles and devices to make flossing easier.
- Have regular dental checkups. Contact your dentist immediately if you experience mouth sores, mouth pain, or loose teeth.
- If decay is a problem, ask your dentist about fluoride rinses or prescription toothpastes that remineralize and harden tooth enamel.
- Consult a physical therapist about facial exercises to help keep your mouth and face more flexible.
- Keep your mouth moist by drinking plenty of water, sucking ice chips, using sugarless gum and hard candy, and avoiding mouthwashes with alcohol. If dry mouth still bothers you, ask your doctor about a saliva substitute—or prescription medications such as pilocarpine hydrochloride or cevimeline hydrochloride—that can stimulate the flow of saliva.
Gastrointestinal (GI) problems: Systemic sclerosis can affect any part of the digestive system. As a result, you may experience problems such as heartburn, difficulty swallowing, early satiety (the feeling of being full after you’ve barely started eating), or intestinal complaints such as diarrhea, constipation, and gas. In cases where the intestines are damaged, your body may have difficulty absorbing nutrients from food. Although GI problems are diverse, here are some things that might help at least some of the problems you have:
- Eat small, frequent meals.
- To keep stomach contents from backing up into the esophagus, stand or sit for at least an hour (preferably 2 or 3 hours) after eating. When it is time to sleep, keep the head of your bed raised using blocks.
- Avoid late-night meals, spicy or fatty foods, alcohol, and caffeine, which can aggravate GI distress.
- Eat moist, soft foods, and chew them well. If you have difficulty swallowing or if your body doesn’t absorb nutrients properly, your doctor may prescribe a special diet.
- Ask your doctor about prescription medications for problems such as diarrhea, constipation, and heartburn. Some drugs called proton pump inhibitors are highly effective against heartburn. Oral antibiotics may stop bacterial overgrowth in the bowel, which can be a cause of diarrhea in some people with systemic sclerosis.
Lung damage: Virtually all people with systemic sclerosis have some loss of lung function. Some develop severe lung disease, which comes in two forms: pulmonary fibrosis (hardening or scarring of lung tissue because of excess collagen) and pulmonary hypertension (high blood pressure in the artery that carries blood from the heart to the lungs). Treatment for the two conditions is different:
- Pulmonary fibrosis may be treated with drugs that suppress the immune system, along with low doses of corticosteroids.
- Pulmonary hypertension may be treated with drugs that dilate the blood vessels, such as prostacyclin, or with newer medications that are prescribed specifically for treating pulmonary hypertension.
Regardless of your particular lung problem or its medical treatment, your role in the treatment process is essentially the same. To minimize lung complications, work closely with your medical team. Do the following:
- Watch for signs of lung disease, including fatigue, shortness of breath or difficulty breathing, and swollen feet. Report these symptoms to your doctor.
- Have your lungs closely checked, using standard lung-function tests, during the early stages of skin thickening. These tests, which can find problems at the earliest and most treatable stages, are needed because lung damage can occur even before you notice any symptoms.
- Get regular flu and pneumonia vaccines as recommended by your doctor. Contracting either illness could be dangerous for a person with lung disease.
Heart problems: Common among people with scleroderma, heart problems include scarring and weakening of the heart (cardiomyopathy), inflamed heart muscle (myocarditis), and abnormal heartbeat (arrhythmia). All of these problems can be treated. Treatment ranges from drugs to surgery and varies depending on the nature of the condition.
Kidney problems: Renal crisis is an uncommon but serious complication in patients with systemic sclerosis. Renal crisis results in severe uncontrolled high blood pressure, which can quickly lead to kidney failure. It’s very important that you take measures to identify and treat the hypertension as soon as it occurs. These are things you can do:
- Check your blood pressure regularly. You should also check it if you have any new or different symptoms such as a headache or shortness of breath. If your blood pressure is higher than usual, call your doctor right away.
- If you have kidney problems, take your prescribed medications faithfully. In the past two decades, drugs known as ACE (angiotensin-converting enzyme) inhibitors, have made scleroderma-related kidney failure a less threatening problem than it used to be. But for these drugs to work, you must take them as soon as the hypertension is present.
Cosmetic problems: Even if scleroderma doesn’t cause any lasting physical disability, its effects on the skin’s appearance—particularly on the face—can take their toll on your self-esteem. Fortunately, there are procedures to correct some of the cosmetic problems scleroderma causes:
- The appearance of telangiectasias—small red spots on the hands and face caused by swelling of tiny blood vessels beneath the skin—may be reduced or even eliminated with the use of guided lasers.
- Facial changes of localized scleroderma—such as the en coup de sabre that may run down the forehead in people with linear scleroderma—may be corrected through cosmetic surgery. (However, such surgery is not appropriate for areas of the skin where the disease is active.)
Having a chronic disease can affect almost every aspect of your life, from family relationships to holding a job. For people with scleroderma, there may be other concerns about appearance or even the ability to dress, bathe, or handle the most basic daily tasks. Here are some areas in which scleroderma could intrude.
Appearance and self-esteem: Aside from the initial concerns about health and longevity, people with scleroderma quickly become concerned with how the disease will affect their appearance. Thick, hardened skin can be difficult to accept, particularly on the face. Systemic scleroderma may result in facial changes that eventually cause the opening to the mouth to become smaller and the upper lip to virtually disappear. Linear scleroderma may leave its mark on the forehead. Although these problems can’t always be prevented, their effects may be minimized with proper treatment. Also, special cosmetics—and in some cases plastic surgery—can help conceal scleroderma’s damage.
Caring for yourself: Tight, hard connective tissue in the hands can make it difficult to do what were once simple tasks, such as brushing your teeth and hair, pouring a cup of coffee, using a knife and fork, unlocking a door, or buttoning a jacket. If you have trouble using your hands, consult an occupational therapist, who can recommend new ways of doing things or devices to make tasks easier. Devices as simple as Velcro fasteners and built-up brush handles can help you be more independent.
Family relationships: Spouses, children, parents, and siblings may have trouble understanding why you don’t have the energy to keep house, drive to soccer practice, prepare meals, or hold a job the way you used to. If your condition isn’t that visible, they may even suggest you are just being lazy. On the other hand, they may be overly concerned and eager to help you, not allowing you to do the things you are able to do or giving up their own interests and activities to be with you. It’s important to learn as much about your form of the disease as you can and to share any information you have with your family. Involving them in counseling or a support group may also help them better understand the disease and how they can help you.
Sexual relations: Sexual relationships can be affected when systemic scleroderma enters the picture. For men, the disease’s effects on the blood vessels can lead to problems achieving an erection. For women, damage to the moisture-producing glands can cause vaginal dryness that makes intercourse painful. People of either sex may find they have difficulty moving the way they once did. They may be self-conscious about their appearance or afraid that their sexual partner will no longer find them attractive. With communication between partners, good medical care, and perhaps counseling, many of these changes can be overcome or at least worked around.
Although your doctors direct your treatment, you are the one who must take your medicine regularly, follow your doctor’s advice, and report any problems promptly. In other words, the relationship between you and your doctors is a partnership, and you are the most important partner. Here’s what you can do to make the most of this important role.
- Get educated: Knowledge is your best defense against this disease. Learn as much as you can about scleroderma, both for your own benefit and to educate the people in your support network.
- Seek support: Recruit family members, friends, and coworkers to build a support network. This network will help you get through difficult times: when you are in pain; when you feel angry, sad, or afraid; or when you’re depressed. Also, look for a scleroderma support group in your community by calling a national scleroderma organization. (See “For More Information.”) If you can’t find a support group, you might want to consider organizing one.
- Assemble a health care team: You and your doctors will lead the team. Other members may include physical and occupational therapists, a psychologist or social worker, a dentist, and a pharmacist.
- Be patient: Understand that a final diagnosis can be difficult and may take a long time. Find a doctor with experience treating people with systemic and localized scleroderma. Then, even if you don’t yet have a specific diagnosis, you will get understanding and the right treatment for your symptoms.
- Speak up: When you have problems or notice changes in your condition, don’t feel too self-conscious to speak up during your appointment or even call your doctor or another member of your health care team. No problem is too small to ask about, and early treatment for any problem can make the disease more manageable.
- Don’t accept depression: Although it’s understandable that a person with a chronic illness such as scleroderma would become depressed, don’t accept depression as a normal consequence of your condition. If depression makes it hard for you to function well, don’t hesitate to ask your health care team for help. You may benefit from speaking with a psychologist or social worker or from using one of the effective medications on the market.
- Learn coping skills: Meditation, calming exercises, and relaxation techniques may help you cope with emotional difficulties and relieve pain and fatigue. Ask a member of your health care team to teach you these skills or to refer you to someone who can.
- Ask the experts: If you have problems doing daily activities, from brushing your hair and teeth to driving your car, consult an occupational or physical therapist. They have more helpful hints and devices than you can probably imagine. Social workers can often help resolve financial and insurance matters.
No one can say for sure when—or if—a cure will be found. But research is providing the next best thing: better ways to treat symptoms, prevent organ damage, and improve the quality of life for people with scleroderma. In the past two decades, multidisciplinary research has also provided new clues for understanding the disease, which is an important step toward prevention and cure.
Studies of the immune system, genetics, cell biology, and molecular biology have helped reveal the causes of scleroderma, improve existing treatment, and create entirely new treatment approaches.
Some advances in the understanding or treatment of scleroderma include the following:
- Building on research that identified a gene associated with scleroderma in Oklahoma Choctaw Native Americans, scientists are using new technology to look for other genes associated with the disease’s development and severity.
- The drug cyclophosphamide has been found effective in treating lung fibrosis. One study suggested that treating lung problems early with this immunosuppressive drug may help prevent further damage and increase chances of survival. In further research assessing the impact of cyclophosphamide on quality of life in people with lung involvement, 47 percent of people on the drug reported their health was somewhat or much better after 1 year, compared with 18 percent in the placebo group.
- ACE inhibitors are used increasingly for scleroderma-related kidney problems. ACE inhibitors have greatly reduced the risk of kidney failure in people with scleroderma. Now there is evidence that use of ACE inhibitors can actually heal the kidneys of people on dialysis for scleroderma-related kidney failure. As many as half the people who continue ACE inhibitors while on dialysis may be able to go off dialysis in 12 to 18 months.
- Several drugs are now available to treat pulmonary hypertension. Previously, pulmonary hypertension was associated with a poor outcome, but medications such as prostacyclins, endothelin-receptor antagonists, and phosphodiesterase inhibitors have increased the quality of life and life expectancy for people with this dangerous form of lung damage.
Other studies are examining the following:
- The immune system: Researchers are looking at the complex immune system trying to determine why the body creates antibodies against its own tissues. Identifying where and when the antibodies are created could lead researchers to find targets for new therapies. Researchers are already trying new therapies, including those that suppress specific parts of the immune system.
- Genes: Studies continue to find the genes that predispose a person to getting scleroderma. Those genes may be targets for future therapies. Researchers are also trying to find genes that indicate who will develop what type of scleroderma; this could someday help doctors intervene early in patients whose prognosis might indicate, for example, pulmonary hypertension.
- Drug therapies: A drug that has been used to treat some cancers has been found to be effective in preventing the development of fibrosis in animal models, and investigators are trying to find out why. Other researchers are testing a drug and comparing it to existing therapies to see if it results in sustained improvement with less toxicity.
- Animal models: Experiments using mice have proved valuable in past research on scleroderma. Further research using existing strains of mice continues. Researchers are also trying to develop new strains that can help in their study of this disease.
- The fibrosis process: Researchers are looking into the many factors that lead to fibrosis. Some are pursuing the genetics of fibrosis. One study is looking at a small molecule, halofuginone, which seems to protect against fibrosis; other small molecules may similarly protect the tissues. Another study looks at a small molecule that apparently contributes to fibrosis. Such discoveries could be future targets for therapies. Another study is pursuing an idea that the cells that overproduce the collagen, fibrocytes, in lung tissue, actually originate in the blood and then move into the damaged lungs; this is contrary to previous assumptions suggesting that the cells that overproduce collagen originate in the lung.
- The identification of several early immune system targets in scleroderma: Building on this research, scientists are continuing to look for ways to treat scleroderma earlier, before it has a chance to cause irreparable damage.
- Cytokines: Studies have shown that certain chemicals called cytokines, made from cells in the body, enhance the development of increased collagen. New agents that counteract these cytokines may be helpful in preventing collagen build up.
Scleroderma research continues to advance as scientists and doctors learn more about how the disease develops and its underlying mechanisms. NIAMS funds a research center specializing in scleroderma at the University of Texas Health Science Center at Houston. Scientists there are conducting laboratory and clinical research on the disease with the goal of translating basic science findings quickly into improved treatment and patient care.
- NIH Clinical Research Trials and You helps people learn more about clinical trials, why they matter, and how to participate. Visitors to the website will find information about the basics of participating in a clinical trial, first-hand stories from actual clinical trial volunteers, explanations from researchers, and links to how to search for a trial or enroll in a research-matching program.
- ClinicalTrials.gov offers up-to-date information for locating federally and privately supported clinical trials for a wide range of diseases and conditions.
- NIH RePORTER is an electronic tool that allows users to search a repository of both intramural and extramural NIH-funded research projects from the past 25 years and access publications (since 1985) and patents resulting from NIH funding.
- PubMed is a free service of the U.S. National Library of Medicine that lets you search millions of journal citations and abstracts in the fields of medicine, nursing, dentistry, veterinary medicine, the health care system, and preclinical sciences.
Scleroderma poses a series of challenges for both patients and their health care teams. The good news is that scientists, doctors, and other health care professionals continue to find new ways to make earlier diagnoses and manage disease better. In addition, active patient support groups share with, care for, and educate each other. The impact of all of this activity is that people with scleroderma do much better and remain active far longer than they did 20 or 30 years ago. As for tomorrow, patients and the medical community will continue to push for longer, healthier, and more active lives for people with the diseases collectively known as scleroderma.

Antibodies. Special proteins produced by the body’s immune system. They recognize and help fight infectious agents, such as bacteria and other foreign substances that invade the body. The presence of certain antibodies in the blood can help to diagnose some diseases, including some forms of scleroderma.
Atherosclerosis. Aabnormal fatty deposits in the inner layers of large or medium-sized arteries, which can lead to hardening and narrowing of the arteries and blockages of the blood supply, especially to the heart.
Autoimmune disease. A disease in which the body’s immune system turns against and damages its own tissues.
Calcinosis. The formation of calcium deposits in the connective tissues, which can be detected by x ray. These deposits are typically found on the fingers, hands, face, and trunk and on the skin above elbows and knees. When the deposits break through the skin, painful ulcers can result.
Calcium channel blockers. Medicines that lower blood pressure, relieve chest pain, and stabilize normal heart rhythms by inhibiting calcium movement into the heart muscles and smooth muscle cells. They are used to treat a variety of conditions and to prevent circulatory and kidney problems in scleroderma.
Collagen. A fabric-like material of fibrous threads that is a key component of the body’s connective tissues. In scleroderma, either too much collagen is produced or it is produced in the wrong places, causing stiff and inflamed skin, blood vessels, and internal organs.
Connective tissue. Tissues such as skin, tendons, and cartilage that support and hold body parts together. The chief component of connective tissue is collagen.
CREST syndrome. An acronym for a collection of symptoms that occur to some degree in all people with systemic sclerosis. The symptoms are calcinosis, Raynaud’s phenomenon, esophageal dysfunction, sclerodactyly, and telangiectasia. Because of the predominance of CREST symptoms in people with limited systemic sclerosis, some people use the term CREST syndrome when referring to that form of the disease.
Eosinophilic fasciitis. A scleroderma-like disorder (often considered to be a localized form of scleroderma) featuring inflammation of the fascia (the thin, sheet-like connective tissues surrounding the muscles and other body structures) and an abnormally high number of a specific kind of white blood cells (eosinophils). The result of the inflammation may be fibrous buildup in the skin of arms and legs, contractures, and carpal tunnel syndrome.
Esophageal dysfunction. Impaired function of the esophagus (the tube connecting the throat and the stomach) that occurs when smooth muscles in the esophagus lose normal movement. In the upper and lower esophagus, the result can be swallowing difficulties. In the lower esophagus, the result can be chronic heartburn or inflammation.
Fibroblast. A type of cell in connective tissue that secretes proteins, including collagen.
Fibrosis. A condition marked by increased fibrous tissue that develops between the cells of various organs or tissues. It is a common feature of scleroderma and some other diseases. Fibrosis causes hardening or stiffening of tissues in the skin, joints, and internal organs.
Graft-versus-host disease. A major complication of bone marrow transplantations and sometimes blood transfusions in which white blood cells called lymphocytes, which are found in the marrow or blood, attack tissues in the body into which they were transplanted.
Pulmonary fibrosis. Hardening or scarring of lung tissue because of excess collagen. Pulmonary fibrosis occurs in a small percentage of people with systemic sclerosis.
Pulmonary hypertension. Abnormally high blood pressure in the arteries supplying the lungs that may be caused by a number of factors, including damage from fibrosis.
Raynaud’s phenomenon. A condition in which the small blood vessels of the hands or feet contract in response to cold or anxiety. As the vessels contract, the hands or feet turn white and cold, then blue. As blood flow returns, they become red. Fingertip tissues may suffer damage, leading to ulcers, scars, or gangrene.
Rheumatic. An adjective used to describe a group of conditions characterized by inflammation or pain in the muscles, joints, and fibrous tissue. Rheumatic diseases or disorders can be related to autoimmunity or other causes.
Sclerodactyly. Thick and tight skin on the fingers, resulting from deposits of excess collagen within skin layers. The condition makes it harder to bend or straighten the fingers. The skin may also appear shiny and darkened, with hair loss.
Systemic condition. A condition involving the body as a whole, as opposed to limited conditions that affect particular parts of the body.
Systemic lupus erythematosus. A systemic rheumatic disease that occurs predominantly in women and is characterized by autoimmune activity, a facial rash across the bridge of the nose and cheeks, Raynaud’s phenomenon, joint pain and swelling, fever, chest pain, hair loss, and other symptoms. Many of its symptoms overlap with those of scleroderma.
Telangiectasia. A condition caused by the swelling of tiny blood vessels, in which small red spots appear on the hands and face. Although not painful, these red spots can create cosmetic problems.
