Sjögren Syndrome Blood Test

What is Sjögren Syndrome?

Sjögren Syndrome is an autoimmune disorder that primarily affects the glands responsible for producing tears and saliva, leading to chronic dry eyes and dry mouth. It is caused by the immune system mistakenly attacking moisture-producing glands, with specific autoantibodies like anti-SSA (Ro) and anti-SSB (La) present in most cases. The Anti-Cyclic Citrullinated Peptide 3 (Anti-CCP3) IgG test is the most important test when overlap syndromes with Rheumatoid Arthritis are suspected.

What causes Sjögren Syndrome?

Sjögren Syndrome is caused by the immune system mistakenly attacking the body's own moisture-producing glands, particularly the lacrimal glands that make tears and salivary glands that produce saliva. This autoimmune attack is characterized by the presence of specific autoantibodies, including anti-SSA (Ro) and anti-SSB (La), which are found in 40-60% of patients. The exact trigger for this immune system malfunction is not fully understood, but genetic factors, hormonal influences, and possibly viral infections like Epstein-Barr virus may play a role in its development.

What is the best test for Sjögren Syndrome?

The Anti-Cyclic Citrullinated Peptide 3 (Anti-CCP3) IgG test is the most important test for Sjögren Syndrome when overlap with Rheumatoid Arthritis is suspected because it detects CCP antibodies that may be present in patients with both conditions. While the primary diagnostic tests for Sjögren Syndrome are anti-SSA (Ro) and anti-SSB (La) antibodies, the Anti-CCP3 test becomes essential when patients show symptoms of both autoimmune disorders, such as joint pain combined with dry eyes and mouth. This test helps identify overlap syndromes and guides your healthcare provider in developing a comprehensive treatment plan that addresses both conditions.

When should I get tested for Sjögren Syndrome?

You should get tested if you experience persistent dry eyes that feel gritty or burning, chronic dry mouth that makes swallowing or speaking difficult, or unexplained joint pain and swelling. Testing becomes especially important if you already have another autoimmune condition like lupus or rheumatoid arthritis, as Sjögren Syndrome often occurs alongside these disorders. You should also consider testing if you have dental problems like frequent cavities despite good oral hygiene, swollen salivary glands, or persistent fatigue that interferes with daily activities.

What are the symptoms of Sjögren Syndrome?
The most common symptoms of Sjögren Syndrome are dry eyes that feel gritty, sandy, or burning, and dry mouth that makes it difficult to swallow dry foods or speak for long periods. You might also experience swollen salivary glands near your jaw, dental cavities and tooth decay, persistent dry cough, vaginal dryness, and skin rashes. Many people with Sjögren Syndrome also feel extreme fatigue, have joint pain and stiffness similar to arthritis, and may notice their eyes are more sensitive to light or have blurred vision.
Who is at risk for Sjögren Syndrome?
Women are nine times more likely than men to develop Sjögren Syndrome, with most cases diagnosed after age 40, though it can occur at any age. You are at higher risk if you already have another autoimmune disease like rheumatoid arthritis, lupus, scleroderma, or thyroid disorders, as Sjögren Syndrome frequently occurs alongside these conditions. Family history also plays a role, with those who have relatives with autoimmune diseases having an increased risk of developing the condition themselves.
What happens if Sjögren Syndrome is left untreated?
Untreated Sjögren Syndrome can lead to serious complications affecting multiple organs and systems. The chronic dry eyes can result in corneal damage, ulcers, and vision problems, while persistent dry mouth significantly increases the risk of tooth decay, gum disease, and oral infections like thrush. Beyond these primary symptoms, untreated Sjögren Syndrome can cause kidney problems, lung inflammation, nerve damage causing numbness and tingling, and in rare cases, an increased risk of developing lymphoma, a type of cancer affecting the lymphatic system.
Can Sjögren Syndrome be diagnosed with a blood test?
Yes, blood tests are essential for diagnosing Sjögren Syndrome and detecting the specific autoantibodies your immune system produces against your own tissues. The most important blood tests measure anti-SSA (Ro) and anti-SSB (La) antibodies, which are present in 40-60% of Sjögren Syndrome patients. Blood tests also check for elevated inflammatory markers like ESR (erythrocyte sedimentation rate) and rheumatoid factor, and the Anti-CCP3 IgG test helps identify patients who have overlap with Rheumatoid Arthritis, allowing for more accurate diagnosis and targeted treatment.
How is Sjögren Syndrome treated?
Treatment for Sjögren Syndrome focuses on relieving symptoms and preventing complications since there is no cure for the condition. For dry eyes, doctors recommend artificial tears, prescription eye drops like cyclosporine or lifitegrast, and sometimes tear duct plugs to retain natural moisture. Dry mouth is managed with saliva substitutes, prescription medications like pilocarpine or cevimeline that stimulate saliva production, and drinking water frequently throughout the day. If you have systemic symptoms like joint pain or organ involvement, your doctor may prescribe immunosuppressive medications like hydroxychloroquine, methotrexate, or corticosteroids to reduce inflammation and control the autoimmune response.
How can I prevent Sjögren Syndrome?
There is no known way to prevent Sjögren Syndrome since it is an autoimmune disorder with genetic and environmental factors that are not fully understood. However, if you have other autoimmune conditions or a family history of autoimmune diseases, staying aware of early symptoms can lead to earlier diagnosis and treatment. Maintaining good overall health through a balanced diet, managing stress, avoiding smoking, and staying hydrated may support your immune system, though these measures cannot prevent the condition from developing if you are genetically predisposed.
What can I do at home for Sjögren Syndrome?
You can manage Sjögren Syndrome symptoms at home by using artificial tears frequently throughout the day, using a humidifier to add moisture to the air in your home, and sipping water constantly to keep your mouth moist. Chewing sugar-free gum or sucking on sugar-free candy stimulates saliva production, while avoiding caffeine, alcohol, and smoking helps prevent further drying of your mouth and eyes. Practicing good oral hygiene with fluoride toothpaste and regular dental checkups is essential to prevent tooth decay, and wearing wraparound sunglasses outdoors protects your eyes from wind and sun that can worsen dryness.
