Systemic Sclerosis (Scleroderma) Blood Test

What is Systemic Sclerosis (Scleroderma)?

Systemic Sclerosis, also known as scleroderma, is a chronic autoimmune disorder that causes hardening and tightening of the skin and connective tissues. It is caused by overproduction of collagen due to immune system dysfunction that attacks healthy tissue. The ANA Screen IFA with Reflex to Titer and Pattern is the most important test for diagnosis because it detects specific autoantibodies present in most scleroderma patients.

What causes Systemic Sclerosis (Scleroderma)?

Systemic Sclerosis is caused by an overactive immune system that mistakenly attacks healthy connective tissue, leading to excessive collagen production. This autoimmune response causes the skin, blood vessels, and internal organs to become thick and hard. While the exact trigger is unknown, genetic factors, environmental exposures, and certain viral infections may play a role in activating the immune system dysfunction that leads to scleroderma.

What is the best test for Systemic Sclerosis (Scleroderma)?

The ANA Screen IFA with Reflex to Titer and Pattern is the most important test for Systemic Sclerosis because it detects antinuclear antibodies present in approximately 95% of scleroderma patients. This test uses immunofluorescence to identify specific autoantibody patterns that help distinguish scleroderma from other autoimmune conditions. High ANA levels with characteristic patterns such as nucleolar or centromere patterns strongly support the diagnosis. The Anti-dsDNA test may provide additional immunological information in select cases where a comprehensive autoimmune profile is needed.

When should I get tested for Systemic Sclerosis (Scleroderma)?

You should get tested if you notice skin thickening or tightening, especially on your fingers, hands, or face. Other warning signs include Raynaud's phenomenon where your fingers turn white or blue in cold temperatures, persistent heartburn or difficulty swallowing, unexplained shortness of breath, or joint pain and stiffness. Early testing is particularly important if you have a family history of autoimmune diseases or if your symptoms are progressively worsening, as early diagnosis allows for better management of organ involvement.

What are the symptoms of Systemic Sclerosis (Scleroderma)?
Systemic Sclerosis symptoms include skin thickening and hardening that typically starts in the fingers and hands, Raynaud's phenomenon causing color changes in fingers and toes when exposed to cold, and persistent digestive issues like heartburn and difficulty swallowing. You might also experience shortness of breath, fatigue, joint pain and stiffness, muscle weakness, and the appearance of small red spots on the skin called telangiectasias. Some people develop calcium deposits under the skin or experience kidney problems and high blood pressure.
Who is at risk for Systemic Sclerosis (Scleroderma)?
Women between ages 30 and 50 are at highest risk for developing Systemic Sclerosis, with the condition affecting women about four times more often than men. People with a family history of scleroderma or other autoimmune diseases have increased risk. Certain occupational exposures to silica dust, organic solvents, or vinyl chloride may elevate risk. African American women tend to develop more severe forms of the disease at younger ages compared to other ethnic groups.
What happens if Systemic Sclerosis (Scleroderma) is left untreated?
Untreated Systemic Sclerosis can lead to serious organ damage and life-threatening complications. The lungs may develop scarring (pulmonary fibrosis) or increased blood pressure in lung arteries, causing severe breathing difficulties. The heart can be affected with abnormal rhythms or heart failure. Kidney crisis with dangerously high blood pressure can occur suddenly. The digestive system may develop severe problems with swallowing and nutrient absorption. Early diagnosis and treatment are essential to slow disease progression and prevent irreversible organ damage.
Can Systemic Sclerosis (Scleroderma) be diagnosed with a blood test?
Blood tests are essential for diagnosing Systemic Sclerosis but are used alongside physical examination and medical history. The ANA Screen IFA test detects autoantibodies present in the vast majority of scleroderma patients and helps confirm the diagnosis. Specific autoantibody patterns can also help identify disease subtypes and predict which organs might be affected. While blood tests cannot diagnose scleroderma by themselves, they provide critical information that supports clinical findings and guides treatment decisions.
How is Systemic Sclerosis (Scleroderma) treated?
Systemic Sclerosis treatment focuses on managing symptoms and preventing organ damage through medications that suppress the immune system, such as methotrexate or mycophenolate. Blood pressure medications called ACE inhibitors protect the kidneys and help with Raynaud's phenomenon. Immunosuppressive drugs may slow skin thickening and lung involvement. Physical therapy maintains joint flexibility and skin elasticity. Treatment is individualized based on which organs are affected, with regular monitoring through blood tests and imaging to track disease progression and adjust medications accordingly.
How can I prevent Systemic Sclerosis (Scleroderma)?
Systemic Sclerosis cannot be prevented because it is an autoimmune condition with no known definitive cause. However, you can reduce risk of triggering or worsening symptoms by avoiding exposure to silica dust and organic solvents in occupational settings. Protecting yourself from cold temperatures helps prevent Raynaud's attacks. Avoiding smoking is crucial as it worsens blood vessel problems and lung complications. If you have a family history of autoimmune diseases, staying aware of early symptoms allows for prompt diagnosis and treatment, which can slow disease progression.
What can I do at home for Systemic Sclerosis (Scleroderma)?
At home, you can manage Systemic Sclerosis symptoms by keeping your body warm and wearing gloves in cold weather to prevent Raynaud's attacks. Gentle stretching exercises and hand therapy maintain flexibility and prevent joint stiffness. Elevate the head of your bed to reduce nighttime heartburn and acid reflux. Use moisturizers regularly to keep skin supple and prevent cracking. Eat smaller, more frequent meals and avoid foods that trigger reflux. Stay physically active within your limits to maintain muscle strength and joint mobility, and manage stress through relaxation techniques as stress can worsen symptoms.
