Sjögren's syndrome is an autoimmune disorder characterized by the body's immune system attacking its own moisture-producing glands, leading to dry mouth (xerostomia) and dry eyes (keratoconjunctivitis sicca).

Dr. Zeng Guosen reply Internal Medicine


Hello, Sjögren's syndrome, commonly known as dry syndrome, is caused by immune dysfunction that leads to the impairment of exocrine gland function, resulting in dry mouth, dry eyes, or enlargement of the exocrine glands, as well as involvement of other joints and internal organs.
Treatment primarily focuses on immunomodulators, with symptomatic management as a secondary approach.
New medications have been developed to help control dry eyes and dry mouth, providing greater comfort for patients.
Sincerely, Dr.
Kuo-Sen Tseng, Internal Medicine.

More Info


Churg-Strauss Syndrome, also known as Eosinophilic Granulomatosis with Polyangiitis (EGPA), is a rare autoimmune condition characterized by inflammation of blood vessels (vasculitis) that can affect multiple organ systems. This syndrome is particularly notable for its association with asthma, eosinophilia (an elevated level of eosinophils, a type of white blood cell), and systemic vasculitis. The condition primarily affects the respiratory system, skin, kidneys, and peripheral nerves.


Symptoms of Churg-Strauss Syndrome
The symptoms of Churg-Strauss Syndrome can vary widely among individuals, but they typically include:
1. Respiratory Symptoms: Patients often present with asthma or worsening asthma symptoms, which may be new-onset or exacerbated. Other respiratory issues can include sinusitis, nasal polyps, and pulmonary infiltrates.

2. Eosinophilia: A significant increase in eosinophils in the blood is a hallmark of the syndrome. This can lead to various symptoms, including fever, fatigue, and weight loss.

3. Skin Manifestations: Skin rashes, including purpura (purple spots caused by bleeding under the skin), nodules, or urticaria (hives), can occur.

4. Neurological Symptoms: Peripheral neuropathy, which may present as numbness, tingling, or weakness in the limbs, is common due to vasculitis affecting the nerves.

5. Gastrointestinal Symptoms: Some patients may experience abdominal pain, diarrhea, or gastrointestinal bleeding due to vasculitis affecting the gastrointestinal tract.

6. Kidney Involvement: Renal involvement can lead to glomerulonephritis, which may present with hematuria (blood in urine) or proteinuria (protein in urine).


Diagnosis
Diagnosis of Churg-Strauss Syndrome typically involves a combination of clinical evaluation, laboratory tests (including blood tests for eosinophil levels and kidney function), imaging studies (such as chest X-rays or CT scans), and sometimes a biopsy of affected tissues to confirm vasculitis.


Treatment Options
The treatment of Churg-Strauss Syndrome focuses on controlling inflammation and managing symptoms. Key treatment strategies include:
1. Corticosteroids: High-dose corticosteroids (such as prednisone) are the mainstay of treatment to reduce inflammation and suppress the immune response. The dosage may be gradually tapered based on the patient's response.

2. Immunosuppressive Agents: In cases of severe disease or when corticosteroids alone are insufficient, additional immunosuppressive medications may be used. These can include cyclophosphamide, azathioprine, or methotrexate.

3. Biologic Therapies: Recently, biologic agents such as mepolizumab (an anti-IL-5 monoclonal antibody) have been used to target eosinophilic inflammation specifically. This can be particularly beneficial for patients with refractory asthma or eosinophilia.

4. Symptomatic Treatment: Management of specific symptoms, such as asthma control with bronchodilators or inhaled corticosteroids, is essential. Patients with peripheral neuropathy may benefit from pain management strategies.

5. Monitoring and Follow-Up: Regular follow-up is crucial to monitor disease activity, adjust treatment as necessary, and manage any potential side effects of medications.


Conclusion
Churg-Strauss Syndrome is a complex condition that requires a multidisciplinary approach for effective management. Early diagnosis and treatment are critical to prevent complications and improve the quality of life for affected individuals. If you suspect you or someone you know may have this syndrome, it is essential to consult a healthcare professional for a thorough evaluation and appropriate management.
