A rare and chronic condition of the skin and body, scleroderma leads to hardening and tightening of the skin, as well as problems with blood vessels, internal organs, and the digestive system. The quality of life can be significantly affected by Scleroderma, which may cause serious complications.
A form of autoimmune disorder, scleroderma occurs when the immune system mistakenly attacks the body's own tissues. In scleroderma, the immune system triggers the overproduction of collagen, a protein normally found in connective tissues. As collagen strengthens and stretches the skin and other tissues, it can cause them to become thick, stiff, and fibrous when too much is present.
The exact cause of scleroderma is unknown, but it may be influenced by genetic, environmental, and hormonal factors. Some possible risk factors for scleroderma include:
Family history of scleroderma or other autoimmune diseases
Gender - women are more likely to develop scleroderma than men
Ethnicity - some ethnic groups, such as African Americans and Native Americans, are more prone to scleroderma than others
Exposure to certain chemicals, such as silica, vinyl chloride, or solvents
Infections, such as cytomegalovirus, Epstein-Barr virus, or Helicobacter pylori
Scleroderma can affect different parts of the body and cause various symptoms, depending on the type and severity of the condition. There are two main types of scleroderma:
Localized scleroderma - this type only affects the skin and does not involve the internal organs. It causes patches or streaks of thickened skin that may be lighter or darker than the surrounding skin. Localized scleroderma may improve or resolve on its own over time and usually does not cause serious complications.
Systemic sclerosis - this type affects the skin and the internal organs, such as the lungs, heart, kidneys, and digestive system. It can cause serious and potentially life-threatening complications. Systemic sclerosis can be further classified into three subtypes: diffuse, limited, and sine sclerosis.
The most common symptoms of scleroderma include:
Skin changes - hardening, tightening, and thickening of the skin, especially on the fingers, hands, feet, and face. The skin may also become shiny, itchy, and prone to ulcers and infections. Some people may develop small red spots (telangiectasia) or calcium deposits (calcinosis) under the skin.
Raynaud’s phenomenon - a condition that affects the blood circulation in the fingers and toes. It causes the digits to turn white, blue, or red and feel numb, painful, or cold in response to cold temperatures or emotional stress.
Digestive problems - difficulty swallowing, heartburn, bloating, constipation, diarrhea, malnutrition, and fecal incontinence. These problems occur because scleroderma can affect the muscles and nerves that control the movement of food through the digestive tract.
Heart and lung problems - shortness of breath, chest pain, cough, fatigue, and dizziness. These problems occur because scleroderma can cause scarring and inflammation of the heart and lung tissues, as well as high blood pressure in the lungs (pulmonary hypertension).
Kidney problems - high blood pressure, protein in the urine, and kidney failure. These problems occur because scleroderma can damage the blood vessels and filters in the kidneys.
Other problems - joint pain and stiffness, muscle weakness, dry eyes and mouth, dental decay, sexual dysfunction, and depression.
Diagnosing scleroderma can be challenging, as the symptoms can vary widely and mimic other conditions. There is no single test that can confirm scleroderma, but the diagnosis is usually based on a combination of:
Medical history - the doctor will ask about the symptoms, family history, and possible exposure to risk factors.
Physical examination - the doctor will examine the skin and other affected areas for signs of scleroderma, such as thickening, tightness, and color changes.
Blood tests - the doctor may order blood tests to check for certain antibodies that are associated with scleroderma, such as anti-nuclear antibodies (ANA), anti-centromere antibodies (ACA), and anti-topoisomerase I antibodies (ATA). However, these antibodies are not specific to scleroderma and may be present in other conditions as well.
Skin biopsy - the doctor may take a small sample of the skin and examine it under a microscope to look for abnormal collagen deposits and other changes.
Imaging tests - the doctor may order imaging tests, such as X-rays, CT scans, or echocardiograms, to check for abnormalities in the lungs, heart, kidneys, and other organs.
There is no cure for scleroderma, but treatment can help manage the symptoms, slow the progression, and prevent or treat its complications. Scleroderma treatment options may vary depending on the type, severity, and location of the condition, as well as the individual's age, health, and preferences.
Medications - there are various medications that can help to reduce the inflammation, pain, and immune reactions in scleroderma. Some examples are:
Blood pressure medications, such as lisinopril, to dilate the blood vessels and improve the blood flow to the fingers, toes, and organs.
Immune suppressants, such as cyclophosphamide or prednisone, to lower the immune system activity and prevent further damage to the tissues.
Stomach acid suppressants, such as omeprazole, to reduce the acid production in the stomach and prevent acid reflux and ulcers.
Antibiotics, such as tetracycline or erythromycin, to treat infections in the skin or digestive tract.
Analgesics, such as aspirin, to relieve the pain and inflammation in the joints and muscles.
Procedures - there are some procedures that can help to treat the complications of scleroderma, such as:
Amputation - removing parts of or whole fingers that have developed gangrene due to poor blood circulation.
Lung transplantation - replacing severely damaged lungs with donor lungs in cases of advanced pulmonary fibrosis or pulmonary hypertension.
Dialysis or kidney transplantation - filtering the blood or replacing the kidneys in cases of kidney failure.
Therapy - there are some therapies that can help to improve the function and quality of life in scleroderma, such as:
Physical therapy - involving exercises and using assistive devices to maintain or restore the mobility, strength, and flexibility of the affected areas.
Occupational therapy - involving training and using adaptive equipment to perform daily activities, such as eating, dressing, and working.
Speech therapy - involving exercises and techniques to improve the swallowing and speaking abilities in cases of scleroderma affecting the mouth and throat.
Psychological therapy - involving counseling and support groups to cope with the emotional and social challenges of living with scleroderma.
There is no known way to prevent scleroderma, as the exact cause is unknown. However, some possible steps to reduce the risk or delay the onset of scleroderma are:
Avoiding or limiting the exposure to chemicals, such as silica, vinyl chloride, or solvents, that may trigger or worsen scleroderma.
Getting regular check-ups and screenings for infections, such as cytomegalovirus, Epstein-Barr virus, or Helicobacter pylori, that may be associated with scleroderma.
Quitting smoking and limiting alcohol consumption, as these habits can impair the blood circulation and damage the blood vessels and organs.
Maintaining a healthy weight and diet, as obesity and malnutrition can increase the inflammation and stress on the body.
Managing stress and practicing relaxation techniques, such as meditation, yoga, or breathing exercises, as stress can aggravate the symptoms and complications of scleroderma.
