What Is Scleroderma?
Derived from the Greek words “sklerosis,”
meaning hardness, and “derma,” meaning skin, scleroderma
literally means hard skin. Though 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 and/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.
What Are the Different Types of Scleroderma?
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 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 and/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. Telangiectasias 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. They 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 and/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-uhs): a
condition caused by the swelling of tiny blood
vessels, in which small red spots appear on the
hands and face. While 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, it 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
and/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 onethird of patients with diffuse disease
develop these severe problems. Early diagnosis and
continual and careful monitoring are important.
What Causes Scleroderma?
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:
While 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 sclerodermalike 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: By
the middle to late childbearing years (ages 30 to 55)
women develop scleroderma 7 to 12 times more often than
men. Because of female predominance at this and all
ages, 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.
Who Gets Scleroderma?
A lthough 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. Estimates for the number of people
in the United States with systemic sclerosis range from
40,000 to 165,000. By contrast, a survey that included
all scleroderma-related disorders, including Raynaud’s
phenomenon, suggested a number between 250,000 and
992,500.
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.
How Is Scleroderma Diagnosed?
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 (lung specialist), or 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 as many as 50 percent of 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, too, 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.
What Other Conditions Can Look
Like Scleroderma?
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 fashi-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.
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. While having a definite
diagnosis may be helpful, you do not need to know the
precise form of your disease to receive proper
treatment.
How Is Scleroderma Treated?
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
like 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
physician. 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:
More than 90 percent of 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, and 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,
such as nifedipine (Procardia*),
which can open up small blood vessels and improve
circulation. Other drugs are in development and may
become available.
- If Raynaud’s leads to skin sores or ulcers,
increasing your dose of calcium channel blockers
(under the direction of your doctor ONLY) 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.
*Brand names included in this
booklet are provided as examples only, and their
inclusion does not mean that these products are endorsed
by the National Institutes of Health or any other
Government agency. Also, if a particular brand name is
not mentioned, this does not mean or imply that the
product is unsatisfactory.
Stiff, painful joints:
In diffuse systemic sclerosis, hand joints can stiffen
due to 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 and/or occupational therapist are extremely
important to prevent loss of joint motion. These
should be started as soon as the diagnosis of
scleroderma is made.
- 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, you may need to see
a dermatologist. To ease dry skin, 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 due to salivary gland damage speeds up
tooth decay; and 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 Salagen or Evoxac, 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 two or three) 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 that 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 such as
cyclophosphamide (Cytoxan) or azathioprine (Imuran),
along with low doses of corticosteroids.
- Pulmonary hypertension may be treated with drugs
that dilate the blood vessels such as prostacyclin
(Iloprost), 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 heart beat (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 occurs in about 10 percent of all patients
with scleroderma, primarily those with early diffuse
scleroderma. 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 the 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, including captopril (Capoten),
enalapril (Vasotec), or lisinopril, 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.)
How Can Scleroderma Affect My Life?
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, and
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 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.
Pregnancy and childbearing:
In the past, women with systemic scleroderma were often
advised not to have children. But thanks to better
medical treatments and a better understanding of the
disease itself, that advice is changing. (Pregnancy, for
example, is not likely to be a problem for women with
localized scleroderma.) Although blood vessel
involvement in the placenta may cause babies of women
with systemic scleroderma to be born early, many women
with the disease can have safe pregnancies and healthy
babies if they follow some precautions.
One of the most important pieces of
advice is to wait a few years after the disease starts
before attempting a pregnancy. During the first 3 years,
you are at the highest risk of developing severe
problems of the heart, lungs, or kidneys that could be
harmful to you and your unborn baby.
If you haven’t developed severe organ
problems within 3 years of the disease’s onset, your
chances of such problems are less and pregnancy would be
safer. But it is important to have both your disease and
your pregnancy monitored regularly. You’ll probably need
to stay in close touch with both the doctor you
typically see for your scleroderma and an obstetrician
who is experienced in guiding high-risk pregnancies.
How Can I Play a Role in My Health Care?
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. (See below.)
- 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; 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 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 selfconscious 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 inquire about, and early treatment for any
problem can make the disease more manageable.
- Don’t accept depression:
While it’s understandable that a person with a
chronic illness like 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.
Is Research Close to Finding a Cure?
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.
Leading the way in funding for this
research is the National Institute of Arthritis and
Musculoskeletal and Skin Diseases (NIAMS), a part of the
Department of Health and Human Services’ National
Institutes of Health (NIH). Other sources of funding for
scleroderma research include pharmaceutical companies
and organizations such as the Scleroderma Foundation,
the Scleroderma Research Foundation, and the Arthritis
Foundation. Scientists at universities and medical
centers throughout the United States conduct much of
this research.
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 recent advances in the
understanding or treatment of scleroderma include the
following:
- A gene associated with scleroderma has been
found in Oklahoma Choctaw Native Americans.
Scientists believe the gene, which codes for a
protein called fibrillin-1, may put people at risk
for the disease. Current studies are using new
technology to look for other genes associated with
the disease’s development and severity.
- The drug cyclophosphamide (Cytoxan) has been
found effective in treating lung fibrosis. One
recent study suggested that treating lung problems
early with this immunosuppressive drug may help
prevent further damage and increase chances of
survival. Further research is assessing the impact
of cyclophosphamide on quality of life in people
with lung involvement.
- ACE inhibitors are used increasingly for
scleroderma-related kidney problems. For the past
two decades, 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 new and exciting drugs are now available
to treat pulmonary hypertension. Previously,
pulmonary hypertension was associated with a poor
outcome, but medications like prostacyclins,
endothelin-receptor antagonists, and
phosphodiesterase inhibitors (Flolan, Tracleer and
Revatio) 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 theory that scleroderma is a more aggressive
disease associated with more internal organ damage
and a worse prognosis in non-Caucasians. Researchers
believe that while factors related to both genetics
and socioeconomic status may play a role,
autoantibodies may be the primary reason that
African Americans have such severe disease. A
current study is examining that theory. Researchers
hope that by better understanding the factors
involved in scleroderma, they can design
interventions that would improve the course and
outcome of the disease.
- The use of ultraviolet-B (UV-B) light to treat
the skin manifestations of localized scleroderma.
Exposure to UV light has been shown to reduce
collagen (which is overproduced in people with
scleroderma) in the skin by inducing enzymes that
break down collagen and by inhibiting the production
of new collagen.
- Changes in the tiny blood vessels of people with
scleroderma. By studying these changes, scientists
hope to find the cause of cold sensitivity in
Raynaud’s phenomenon and a way to control the
problem.
- 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 skin thickening.
- Skin changes in laboratory mice in which a
genetic defect prevents the breakdown of collagen,
leading to thick skin and patchy hair loss.
Scientists hope that by studying these mice they can
answer many questions about skin changes in
scleroderma. Scientists are also working to
establish mouse models for other problems related to
scleroderma. These models will make it easier to
understand these problems and develop treatments for
them.
Scleroderma research continues to
advance as scientists and doctors learn more about how
the disease develops and its underlying mechanisms. The
NIAMS funds a research center specializing in
scleroderma at the University of Texas-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.

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.
