What is the initial management for patients with Sjögren's (Sjögren's syndrome) syndrome?

Initial Management of Sjögren's Syndrome

The first therapeutic approach to Sjögren's syndrome must distinguish between sicca symptoms (which require topical/symptomatic treatment) and systemic disease (which requires immunosuppression), as these are fundamentally different conditions requiring completely different management strategies. 1, 2

Multidisciplinary Coordination

• A specialist in autoimmune diseases should coordinate all diagnostic and therapeutic processes through shared decision-making with the patient 1
• Primary care physicians and other health professionals should be involved in ongoing management 1

Management of Sicca Symptoms (First Priority)

Ocular Dryness

• Start with artificial tears containing methylcellulose or hyaluronate at least twice daily 2, 3
• Add ocular gels or ointments for nighttime use 2
• For moderate to severe or refractory cases, prescribe topical cyclosporine drops 2, 3
• Consider autologous serum eye drops for severe refractory cases 2, 4
• Avoid preservative-containing drops when possible, as they can worsen irritation 5

Oral Dryness

The approach depends on objective salivary gland function, not just subjective complaints 2:

• Mild dysfunction: Non-pharmacological stimulation with sugar-free gum, xylitol lozenges, or frequent water sips 2, 4
• Moderate dysfunction: Pharmacological stimulation with muscarinic agonists 2, 4
  • Pilocarpine 5 mg four times daily (FDA-approved dose for Sjögren's) 6
  • Cevimeline is an alternative 2
  • These require residual salivary function to be effective 7
  • Allow at least 6 weeks to assess efficacy 6
• Severe dysfunction: Saliva substitutes (oral sprays, gels, or rinses with neutral pH and fluoride) 2, 4

Additional Sicca Measures

• Implement intense oral hygiene to prevent dental cavities and gum disease 7
• Consider lacrimal punctal occlusion to reduce tear drainage in severe cases 5

Management of Constitutional Symptoms

• Evaluate for concomitant conditions that amplify fatigue and pain: fibromyalgia, depression, hypothyroidism 2, 4
• Use analgesics following the WHO analgesic ladder for musculoskeletal pain 2
• Consider hydroxychloroquine for fatigue and arthralgias, though evidence for efficacy is limited 2, 3
• Short-term moderate-dose glucocorticoids may be used for acute pain flares 2

Assessment for Systemic Disease

Before initiating any systemic therapy, assess disease activity:

• Use the EULAR Sjögren's Syndrome Disease Activity Index (ESSDAI) to quantify systemic involvement 2, 3
  • Low activity: ESSDAI 1-4
  • Moderate activity: ESSDAI 5-13
  • High activity: ESSDAI ≥14 1
• Obtain baseline chest radiography to screen for pulmonary involvement 2, 3
• Check serologic markers: anti-Ro/SSA antibodies, ANA, cryoglobulins, complement levels (C3, C4) 2
• Monitor for lymphoma development, especially in patients with decreased C4 levels 2, 3

Management of Active Systemic Disease

Only use systemic immunosuppression for active systemic disease with ESSDAI ≥1, never for sicca symptoms alone 1, 2:

Sequential Therapeutic Approach

1. First-line: Glucocorticoids at minimum dose and shortest duration necessary 2, 4
2. Second-line: Immunosuppressive agents as glucocorticoid-sparing options (cyclophosphamide, azathioprine, methotrexate, leflunomide, mycophenolate mofetil) 2, 4
3. Third-line: Biologic therapies (rituximab) for severe, refractory systemic disease 1, 2, 4

Organ-Specific Considerations

• Pulmonary disease: Short courses of systemic steroids, bronchodilators, and/or inhaled corticosteroids 2
• B-cell lymphoma: Treatment according to histological subtype and disease stage 1, 2

Preventive Measures

• Strongly recommend smoking cessation for all patients 1, 2, 3
• Ensure influenza and pneumococcal vaccination 2, 3
• Monitor for side effects of immunosuppressive medications 2

Critical Pitfalls to Avoid

• Never use systemic immunosuppression to treat sicca symptoms 2, 4
• Do not base oral dryness treatment on subjective feelings alone; assess objective salivary gland function 2
• Avoid prolonged glucocorticoid use without implementing steroid-sparing strategies 2, 3, 4
• Do not overlook the need for multidisciplinary care for complex manifestations like neuropathy or interstitial lung disease 2, 4
• Remember that no therapy has been shown to reverse glandular dysfunction or cure sicca symptoms 1
