What is Sjögren's Syndrome?
Sjögren's syndrome is a chronic autoimmune disease primarily affecting the body's ability to produce moisture in the eyes and mouth. This results in dry eyes and mouth, but it can also affect other parts of the body, leading to fatigue, joint and muscle pain, and potential damage to organs such as the lungs, kidneys, and nervous system.
Sjögren's syndrome is more common among women and can occur independently or alongside other autoimmune conditions such as rheumatoid arthritis or systemic lupus erythematosus.
Symptoms of Sjögren's Syndrome
Sjögren's syndrome primarily manifests through dry eyes and mouth, but can also cause:
- Dry and irritated skin, which can lead to itching and redness.
- Fatigue and general malaise.
- Joint and muscle pain.
- Swelling of glands around the face and neck.
- Dry mucous membranes in the nose and throat, which can lead to hoarseness and a dry cough.
- Vaginal dryness, which can cause pain and an increased risk of fungal infections.
- Difficulty swallowing and chewing due to dry mouth.
- Gastrointestinal issues such as nausea, abdominal pain, and digestive problems.
- Skin changes may include dryness, itching, and rashes, particularly on the lower legs. Additionally, individuals with Sjögren's syndrome may experience increased sun sensitivity.
Sjögren's syndrome can present in "flares"—periods when symptoms worsen—followed by periods of milder symptoms. The duration and frequency of these flares vary between individuals, where some may experience short, mild episodes while others have prolonged and more severe periods of symptomatic exacerbation.
Causes of Sjögren's Syndrome
The cause of Sjögren's syndrome is not fully understood, but it is believed to be a combination of genetic and environmental factors that trigger an autoimmune reaction where the immune system attacks the body's own tissues.
How is Sjögren's Syndrome Diagnosed?
To diagnose Sjögren's syndrome, various tests and evaluations are performed. Doctors may use physical examinations, the patient's symptom history, and blood tests including S-ANA (Antinuclear Antibodies) to identify specific antibodies and inflammatory markers characteristic of the disease. Blood tests can also be used to assess the function of the affected glands and to screen for potential kidney inflammation.
Treatment and Relief for Sjögren's Syndrome
Since there is currently no cure that completely eliminates Sjögren's syndrome, care is focused on relieving symptoms, preventing complications, and improving quality of life. Treatment is tailored individually based on the severity of the symptoms and which organs are affected.
Medical Treatment
For most people, local treatment is sufficient, but for more extensive symptoms, systemic medication may be required:
- Eye Treatment: In addition to over-the-counter tear substitutes, doctors may prescribe anti-inflammatory eye drops (such as cyclosporine) to increase natural tear production.
- Saliva Stimulants: Medications such as pilocarpine are available to stimulate the salivary glands to produce more saliva.
- Immunomodulating Drugs: If the disease affects joints, muscles, or internal organs, anti-rheumatic drugs or corticosteroids may be prescribed to suppress the body's autoimmune attack.
Surgical Aids
For extremely dry eyes where drops are not sufficiently effective, a minor procedure can be performed to insert punctual plugs. These small plugs are placed in the tear ducts to prevent the small amount of tear fluid present from draining away, keeping the eye moist for longer.
Lifestyle and Self-Care: Tips for Daily Life
Many people with Sjögren's syndrome can take several steps themselves to ease daily life and reduce the risk of secondary problems such as cavities or eye infections.
Creating a Gentle Environment
Mucous membranes are sensitive to external influences. It is therefore wise to try to avoid:
- Drafts and Air Conditioning: Strong air currents can quickly dry out the eyes.
- Smoky Environments: Tobacco smoke is highly irritating to both the eyes and respiratory tract.
- Dry Indoor Air: Using a humidifier, especially in the bedroom during the winter months, can make a significant difference in sleep quality.
Diet and Oral Hygiene
Since saliva has a protective effect against bacteria, dry mouth entails a significantly increased risk of cavities (caries).
- Fluid Intake: Drink small sips of water often to keep the mouth moist, but avoid sugary drinks like juice or soda, as they cause extra damage to the teeth when the protective saliva is missing.
- Stimulate Saliva: Use sugar-free gum or fluoride lozenges to keep saliva production active.
- Night Care: Consider using a thicker eye ointment or specific nighttime eye creams before going to bed, as tear production often decreases further during sleep.
