The symptoms of scleroderma depend on the type of scleroderma present and the
extent of external and internal involvement in the individual affected. Because
scleroderma can affect the skin, esophagus, blood vessels, kidneys, lungs, blood
pressure and bowels, the symptoms it causes can involve many areas of the body.
Scleroderma affects the skin to cause local or widespread signs of
inflammation (redness, swelling, tenderness, itching, and pain) that can lead to
skin tightness or hardening. These skin changes can be widespread, but it's most
common for them to affect the fingers, feet, face, and neck. This can lead to decreased
range of motion of the fingers, toes, and jaw. Tiny areas of calcification (calcinosis),
while not common, can sometimes be noticed as hard nodules at the tips of the
elbows or in the fingers.
Scleroderma affecting the esophagus leads to heartburn. This is directly a
result of stomach acid flowing back up into the esophagus. Sometimes this can
lead to scarring of the esophagus, resulting in narrowing with difficulty swallowing food and/or localized
pain in the central chest.
Blood vessels that can be affected include the tiny arterioles of the finger
tips, toes, and elsewhere. These vessels can have a tendency to spasm when the
areas are exposed to cold, leading to blueness, whiteness, and redness of
involved fingers, toes, and sometimes nose or ears. These color changes are
referred to as Raynaud's phenomenon. Raynaud's phenomenon can cause inadequate
supply of oxygen to the involve tips of fingers or toes, causing tiny ulcers or
blackened (dead) skin. Sometimes Raynaud's phenomenon is also associated with
tingling. Other blood vessels that can be involved in scleroderma are the tiny
capillaries of the face, lips, mouth, or fingers. These capillaries widen
(dilate), forming tiny, red blanching spots, called telangiectasias.
Elevated blood pressure is potentially serious and can lead to kidney damage.
Symptoms include headache, fatigue, and in severe cases, stroke. Blood pressure monitoring and control is essential.
Inflammation of the lungs in scleroderma can cause scarring, resulting in
shortness of breath, especially with physical exertion. Elevated pressure in the
arteries to the lungs (pulmonary hypertension) can also cause shortness of
breath and difficulty getting an adequate breath with activity.
Scleroderma affecting the large bowel (colon) most often causes constipation
but can also lead to cramping and diarrhea. When this is severe, complete
stool blockage (fecal impaction) can result.
High blood pressure, also known as hypertension, is a repeatedly
elevated blood pressure exceeding 140 over 90 mmHg -- a systolic pressure above
140 with a diastolic pressure above 90. There are two causes of high blood pressure, primary and secondary. Primary high blood pressure is much more common that secondary and its basic causes or underlying defects are not always known. It is known that a diet high in salt increases the risk for high blood pressure, as well as high cholesterol. Genetic factors are also a primary cause. Secondary high blood pressure is generally caused by another condition such as renal hypertension, tumors, and other conditions. Treatment for high blood pressure is generally lifestyle changes and if necessary, diet.
GERD (gastroesophageal reflux disease) is a condition in which the acidified liquid
contents of the stomach backs up into the esophagus. The symptoms of uncomplicated GERD are heartburn,
regurgitation, and nausea. Effective treatment is available for most patients with GERD.
Sjögren's syndrome is an autoimmune disease involving the abnormal production of extra antibodies that attack the glands and connective tissue. Sjögren's syndrome with gland inflammation (resulting dry eyes and mouth, etc.) that is not associated with another connective tissue disease is referred to as primary Sjögren's syndrome. Sjögren's syndrome that is also associated with a connective tissue disease, such as rheumatoid arthritis, systemic lupus erythematosus, or scleroderma, is referred to as secondary Sjögren's syndrome. Though there is no cure for Sjögren's syndrome, the symptoms may be treated by using lubricating eye ointments, drinking plenty of water, humidifying the air, and using glycerin swabs. Medications are also available to treat dry eye and dry mouth.
Raynaud's phenomenon is characterized by a pale-blue-red sequence of color changes of the digits, most commonly after exposure to cold. Occurring as a result of spasm of blood vessels, the cause is unknown. Symptoms of Raynaud's phenomenon depend on the severity, frequency, and duration of the blood vessel spasm. Treatments include protection of the digits, medications, and avoiding emotional stresses, smoking, cold temperature, and tools that vibrate the hands.
Small intestinal bacterial overgrowth (SIBO) refers to a condition in which abnormally large numbers of bacteria (at least 100,000 bacteria per ml of fluid) are present in the small intestine and the types of bacteria in the small intestine resemble more the bacteria of the colon than the small intestine. There are many conditions associated with small intestinal bacterial overgrowth, to include: diabetes, scleroderma, Crohn's disease, and others. There is a striking similarity between the symptoms of irritable bowel syndrome and SIBO. It has been theorized that SIBO may be responsible for the symptoms of at least some patients with irritable bowel syndrome. Symptoms of SIBO include: excess gas, abdominal bloating, diarrhea, and abdominal pain.
A keloid is a scar that doesn't know when to stop. When the cells keep on reproducing, the result is an overgrown (hypertrophic) scar or a keloid. A keloid looks shiny and is often dome-shaped, ranging in color from slightly pink to red. It feels hard and thick and is always raised above the surrounding skin.
Pulmonary fibrosis is scarring throughout the lungs. Pulmonary fibrosis can be caused by many conditions including chronic inflammatory processes, infections, environmental agents, exposure to ionizing radiation, chronic conditions, and certain medications. Symptoms include shortness of breath, coughing, and diminished exercise tolerance. Treatment options are dependent on the type of pulmonary fibrosis; lung transplant and/or medications are optons.
Dysphagia or difficulty in swallowing, swallowing problems. Dysphagia is due to problems in nerve or muscle control. It is common, for example, after a stroke. Dysphagia compromises nutrition and hydration and may lead to aspiration pneumonia and dehydration.
Pulmonary hypertension is an abnormal elevation of the pressure in the pulmonary circulation caused by the constriction of the blood vessels that supply blood to the lungs. Shortness of breath and dizziness are symptoms of pulmonary hypertension. Treatment involves diuretics, blood thinners, calcium channel blockers, and using supplemental oxygen to increase blood oxygen levels.
Pericarditis is the inflammation of the pericardial sac that surrounds the heart. The causes of pericarditis include injury from heart attack, heart surgery, trauma; viral or fungal infection, HIV, tumors, mixed connective tissue disease, metabolic disease, medication reactions, or idiopathic. Treatment for pericarditis is generally medication, however, sometimes surgery is necessary.
Primary Biliary Cirrhosis is a chronic disease characterized by progressive inflammation and destruction of small bile ducts within the liver. The bile ducts transport bile from the liver to the intestine for the absorption of fat and elimination of waste products. The causes of Primary Biliary Cirrhosis may involve autoimmunity, infection, or genetic predisposition, acting alone or in combination. There are many medications and treatment options available for those with this and other associated diseases of Primary Biliary Cirrhosis.
Interstitial lung disease, is a term to describe a certain lung condition. Causes of interstitial lung disease include lung infection, exposure to toxins in the environment (asbestos for example), medications (chemotherapy), radiation therapy, and chronic autoimmune disorders. Common symptoms of interstitial lung disease include a dry cough and shortness of breath. Diagnosis and treatment depend upon the cause of the condition.
Polymyositis is a disease of the muscle featuring inflammation of the muscle fibers. It results in weakness of the muscles which can be severe and when associated with skin rash, is referred to as dermatomyositis. Although the cause of this disease is unknown, diagnosis includes physical examination of muscle strength, blood tests for muscle enzymes, electrical tests of muscle and nerves, and conformation by a muscle biopsy. Treatment of Polymyositis and Dermatomyositis includes high doses of cortisone-related medications, immune suppression, and physical therapy.
Connective tissue disease is when the body's connective tissues come under attack, possibly becoming injured by inflammation. Inherited connective tissue diseases include Marfan syndrome and Ehlers-Danlos syndrome. Systemic lupus erythematosus, rheumatoid arthritis, scleroderma, polymositis, and dermatomyositis are examples of connective tissue diseases that have no known cause.
Connective tissue diseases are disorders featuring abnormalities involving the collagen and elastin.
Connective tissue diseases that are strictly inheritable include Marfan syndrome and Ehlers-Danlos syndrome. The classic immune-related connective tissue diseases include systemic lupus erythematosus, rheumatoid arthritis, scleroderma, polymyositis, and dermatomyositis. Treatment is often directed at suppressing the inflammation present in the tissues by using anti-inflammatory and immunosuppressive medications.
Preeclampsia is related to increased blood pressure and protein in the mother's urine. Preeclampsia typically begins after the 20th week of pregnancy. When preeclampsia causes seizures, it is termed "eclampsia" and is the second leading cause of maternal death of in the US. Preeclampsia is the leading cause of fetal complications. Risk factors for preeclampsia include high blood pressure, obesity, multiple births, and women with preexisting medical conditions such as diabetes, kidney disease, rheumatoid arthritis, lupus, or scleroderma. Pregnancy planning and lifestyle changes may reduce the risk of preeclampsia during pregnancy.
Bowel or fecal incontinence refers to the loss of voluntary control of stool, or bowel movements. The condition can include partial incontinence, in which a person loses only a small amount of liquid waste, to complete incontinence, in which the entire bowel movement cannot be controlled. Diet changes and elimination of certain medications can help patients to regain bowel control. Treatment involves a combination of medication, biofeedback, and exercise.
Eosinophilic fasciitis is a skin disease that causes thickening and inflammation of the skin and fascia. Symptoms include redness, warmth, and hardening of the skin, as well as occasional tissue and joint pain. Treatment for eosinophilic fasciitis aims to eliminate inflammation through the use of aspirin, NSAIDs, and cortisone. Aggressive forms of eosinophilic fasciitis may require the use of immune suppression medications.
