What is Systemic Sclerosis?
Systemic sclerosis, also known as scleroderma, is a rare chronic autoimmune disease characterized by the hardening and tightening of the skin and connective tissues. It can also affect internal organs such as the lungs, heart, kidneys, and digestive tract. The disease causes excessive collagen production leading to thickened, stiff tissues.
Systemic sclerosis can vary from mild skin changes to severe organ damage.
What Are the Symptoms of Systemic Sclerosis?
Symptoms may develop gradually and vary depending on the extent of skin and organ involvement. Common signs include:
- Thickening and hardening of the skin, often starting on the fingers and hands
- Raynaud’s phenomenon (color changes, numbness, or pain in fingers and toes triggered by cold or stress)
- Swelling and stiffness in fingers and joints
- Skin discoloration or shiny skin
- Difficulty swallowing due to esophageal involvement
- Shortness of breath if lungs are affected
- Fatigue and muscle weakness
- Digestive problems like acid reflux or constipation
What Causes Systemic Sclerosis?
The exact cause of systemic sclerosis is unknown but involves autoimmune dysfunction, where the immune system attacks the body’s tissues. Factors contributing to the disease include:
- Genetic predisposition
- Environmental triggers such as exposure to certain chemicals or infections
- Abnormal blood vessel function leading to tissue damage
- Overproduction of collagen by fibroblasts causing fibrosis
How is Systemic Sclerosis Diagnosed?
Diagnosis is based on clinical features and several tests:
- Physical examination focusing on skin changes and signs of Raynaud’s phenomenon
- Blood tests for specific autoantibodies such as anti-centromere and anti-Scl-70 antibodies
- Imaging studies like chest X-ray or CT scan to check lung involvement
- Pulmonary function tests to assess lung capacity
- Esophageal tests if swallowing difficulties are present
How is Systemic Sclerosis Treated?
There is no cure for systemic sclerosis, but treatment aims to manage symptoms and prevent complications.
- Medications:
- Immunosuppressants to reduce autoimmune activity
- Vasodilators to improve blood flow and reduce Raynaud’s symptoms
- Proton pump inhibitors for acid reflux
- Anti-inflammatory drugs to relieve joint pain
- Lifestyle Measures:
- Avoid cold exposure and manage stress to reduce Raynaud’s attacks
- Skin care to prevent ulcers and infections
- Regular exercise to maintain joint mobility
- Regular Monitoring:
- Ongoing evaluation for lung, kidney, and heart function to detect complications early
Complications of Systemic Sclerosis
Potential serious complications include:
- Pulmonary hypertension (high blood pressure in lung arteries)
- Lung fibrosis leading to breathing difficulties
- Kidney failure in severe cases
- Heart problems including arrhythmias and heart failure
- Digital ulcers and infections due to poor blood flow
Living with Systemic Sclerosis
Living with systemic sclerosis requires regular medical care and lifestyle adjustments. Early diagnosis and treatment improve outcomes and quality of life. Support groups and counseling can provide emotional support and practical advice for coping with the disease.
