What is the treatment approach for a middle-aged female patient with Sjögren's syndrome?

Treatment of Sjögren's Syndrome

Treatment of Sjögren's syndrome requires a clear distinction between managing sicca (dryness) symptoms with topical and muscarinic therapies versus treating systemic disease with immunosuppression, coordinated through a multidisciplinary team approach. 1, 2

General Treatment Framework

The management strategy must be organized into three distinct tiers, as these require fundamentally different therapeutic approaches 1, 2:

1. Sicca symptom management (topical therapies)
2. Constitutional symptom management (analgesics, hydroxychloroquine)
3. Systemic disease management (immunosuppression)

A critical pitfall is using systemic immunosuppression for sicca symptoms alone—this is not recommended and exposes patients to unnecessary risks. 2

Management of Sicca Symptoms

Ocular Dryness (Keratoconjunctivitis Sicca)

First-line treatment:

• Artificial tears containing methylcellulose or hyaluronate, applied at least twice daily 1, 2
• Ocular gels and ointments for nighttime use in persistent cases 1

Refractory cases:

• Topical cyclosporine drops 2, 3
• Autologous serum eye drops 1, 2

Oral Dryness (Xerostomia)

Treatment must be based on objective measurement of residual salivary gland function, not subjective symptoms alone—this is a common error. 2

For mild dysfunction:

• Non-pharmacological stimulation: sugar-free gum, xylitol lozenges, frequent water sips 1, 2

For moderate dysfunction with residual glandular function:

• Muscarinic agonists (pilocarpine or cevimeline) are the cornerstone of therapy 1, 2, 4
• These agents require residual salivary function to be effective 5, 6

For severe dysfunction without salivary production:

• Saliva substitutes (oral sprays, gels, or rinses with neutral pH and fluoride) 2
• Rigorous oral hygiene to prevent infections and caries 1

Management of Constitutional Symptoms

Before initiating treatment, evaluate for concomitant conditions that may contribute to fatigue or pain, including fibromyalgia, depression, and hypothyroidism. 1, 2

For musculoskeletal pain:

• Analgesics following the WHO analgesic ladder based on pain severity 1, 2
• Short-term moderate-dose glucocorticoids for acute pain flares 1, 2

For fatigue and arthralgias:

• Hydroxychloroquine may be prescribed, though evidence for efficacy is limited 2, 3

Management of Systemic Disease

Treatment must be tailored to organ-specific severity using ESSDAI (EULAR Sjögren's Syndrome Disease Activity Index) definitions, following a sequential therapeutic approach. 1, 2

Sequential Treatment Algorithm

Step 1: Glucocorticoids

• First-line treatment for active systemic disease 1, 2
• Dose: 0.5-1.0 mg/kg for interstitial lung disease 1
• Critical: Minimize dose and duration—prolonged use without steroid-sparing strategies must be avoided 1, 2

Step 2: Immunosuppressive Agents (as glucocorticoid-sparing agents)

• Mycophenolate mofetil 1, 2
• Azathioprine 1, 2
• Cyclophosphamide 2, 4
• Methotrexate 2
• Leflunomide 2

Step 3: Biologic Therapies

• Rituximab for severe, refractory systemic disease 2, 5
• Anti-TNF agents have demonstrated lack of efficacy in controlled trials 3

Organ-Specific Considerations

Pulmonary involvement:

• Short course of systemic steroids 1, 2
• Bronchodilators and/or inhaled corticosteroids 1, 2
• For interstitial lung disease: systemic corticosteroids 0.5-1.0 mg/kg with mycophenolate mofetil or azathioprine as steroid-sparing agents 1

B-cell lymphoma (occurs in 2-5% of patients):

• Individualized treatment according to histological subtype and disease stage 2, 7
• Rituximab may be considered 4, 5

Surveillance and Monitoring

Active clinical surveillance for lymphoproliferative complications is essential, particularly in high-risk patients. 8

High-risk features requiring enhanced surveillance:

• Persistent salivary gland swelling 8
• Vasculitis and palpable purpura 8
• Lymphadenopathy 8
• Low complement levels (C3 or C4) 8, 7
• Monoclonal gammopathy 8
• Cryoglobulins 8
• Cytopenias (anemia, leukopenia, lymphopenia, neutropenia, thrombocytopenia) 8

Regular assessment using ESSDAI index is crucial for guiding therapeutic decisions. 1, 2

Multidisciplinary Care Requirements

The care team must include: 8, 1, 2

• Rheumatologist (coordinator)
• Primary care physician
• Pulmonologist (for respiratory manifestations)
• Ophthalmologist (for ocular management)
• Dentist (for oral care)
• Pathologist and radiologist (for diagnostic evaluation)
• Oncologist (when lymphoproliferative complications are suspected)

Overlooking the need for multidisciplinary care, especially for complex manifestations like neuropathy or interstitial lung disease, is a critical error. 2

Essential Preventive Measures

• Smoking cessation must be strongly recommended for all patients 1, 2
• Influenza and pneumococcal vaccination 1, 2
• Monitor for potential side effects of immunosuppressive medications 1, 2

Key Pitfalls to Avoid

• Confusing treatment of sicca symptoms with systemic disease—these require fundamentally different approaches 2
• Basing oral dryness treatment on subjective feelings rather than objective measurement of salivary gland function 2
• Using systemic immunosuppression for sicca symptoms alone 2
• Continuing glucocorticoids long-term without implementing steroid-sparing strategies 1, 2
• Failing to screen for lymphoma risk factors and provide appropriate surveillance 8
