How are Sjogren's syndrome symptoms managed?

Management of Sjögren's Syndrome Symptoms

The management of Sjögren's syndrome symptoms requires a targeted approach addressing both sicca symptoms and systemic manifestations, with topical therapies as first-line treatment for dryness and systemic therapies reserved for patients with active systemic disease. 1, 2

Management of Oral Dryness

• For mild salivary gland dysfunction, non-pharmacological stimulation (sugar-free gum, frequent sips of water) is recommended 3
• For moderate glandular dysfunction, muscarinic agonists such as pilocarpine (5 mg four times daily) or cevimeline may be considered 1, 4
• For patients with no salivary output, saliva substitution is the preferred therapeutic approach 1
• Pilocarpine is FDA-approved for Sjögren's syndrome at a dose of 5 mg four times daily, with efficacy established by 6 weeks of use 4
• Common side effects of pilocarpine include sweating (40%), urinary frequency (10%), nausea (9%), and flushing (9%) 4
• Patients with moderate hepatic impairment should start with 5 mg twice daily, and use is not recommended in severe hepatic insufficiency 4

Management of Ocular Dryness

• First-line therapy includes artificial tears containing methylcellulose or hyaluronate at least twice daily, with frequency increased as needed 1
• Preservative-free formulations are recommended for patients requiring four or more applications per day 1, 2
• Ophthalmic ointments can be used before bedtime for overnight symptom control, followed by morning lid hygiene to prevent blepharitis 1
• For refractory or severe ocular dryness, short-term (2-4 weeks) topical corticosteroids may be considered 1
• Topical cyclosporine A is recommended for patients who don't respond to artificial tears 1, 2
• Autologous serum eye drops may be used in cases that don't respond to other therapies 1

Management of Constitutional Symptoms

• Evaluate for contributing conditions that may worsen fatigue or pain 3, 2
• For musculoskeletal pain, use analgesics according to pain severity following the WHO pain ladder 2
• For chronic, non-inflammatory pain, physical activity and aerobic exercise are recommended rather than medications 1, 2
• Hydroxychloroquine may be considered for fatigue and arthralgias, though evidence for efficacy is limited 2, 5
• Antidepressants and anticonvulsants (gabapentin, pregabalin, amitriptyline) may be considered for chronic neuropathic pain 1, 6
• Avoid prolonged use of NSAIDs or glucocorticoids for chronic daily non-inflammatory pain 1

Management of Systemic Disease

• Systemic therapies should be restricted to patients with active systemic disease 1, 2
• Treatment should be tailored to organ-specific severity using the EULAR Sjögren's Syndrome Disease Activity Index (ESSDAI) definitions 1
• For systemic disease, follow a sequential approach: 3, 6
  1. Glucocorticoids (minimum dose and duration necessary)
  2. Immunosuppressive agents as steroid-sparing options
  3. Biological therapies for refractory cases
• Immunosuppressive agents (cyclophosphamide, azathioprine, methotrexate, leflunomide, mycophenolate) may be used primarily as glucocorticoid-sparing agents 1, 6
• B-cell targeted therapies, particularly rituximab, may be considered for patients with severe, refractory systemic disease 1, 7
• Treatment of B-cell lymphoma should be individualized according to histological subtype and disease stage 1

Common Pitfalls to Avoid

• Failing to distinguish between treatment of sicca symptoms versus systemic disease 3
• Using systemic therapies for patients with only sicca symptoms 1, 2
• Prolonged use of glucocorticoids without appropriate steroid-sparing strategies 3
• Overlooking the need for multidisciplinary care, especially for complex manifestations like neuropathy 6
• Continuing muscarinic agonists despite intolerable side effects (sweating, urinary frequency) 4, 8
• Using preserved artificial tears in patients requiring frequent applications 1, 2
• Prolonged use (>2-4 weeks) of topical corticosteroids for ocular symptoms, which can lead to complications 1
