From the Guidelines
The next steps in management for a patient with elevated SSA (Sjögren's syndrome antigen) antibodies should focus on comprehensive evaluation and symptom-based treatment, prioritizing the use of topical therapies for dryness and considering systemic therapies for active systemic disease, as recommended by the European League Against Rheumatism (EULAR) 1. The management approach should include a thorough clinical assessment to determine if the patient has Sjögren's syndrome or another autoimmune condition, as SSA antibodies can be present in various autoimmune diseases. This evaluation should include:
- A complete history focusing on sicca symptoms (dry eyes, dry mouth)
- Physical examination
- Additional testing such as ocular surface staining, salivary flow measurement, and possibly minor salivary gland biopsy For symptomatic management, the following options can be considered:
- Artificial tears (preservative-free) used frequently during the day, with more viscous formulations at bedtime
- Oral dryness management with sugar-free lozenges, frequent water sipping, and saliva substitutes
- Secretagogues like pilocarpine (5-10 mg three times daily) or cevimeline (30 mg three times daily) to stimulate saliva production
- Hydroxychloroquine (200-400 mg daily) to address fatigue and arthralgia
- Immunossuppressants such as methotrexate (starting at 7.5-10 mg weekly) or mycophenolate mofetil for severe extraglandular disease Regular monitoring for disease progression and complications like lymphoma is essential, with follow-up appointments every 3-6 months, as suggested by recent guidelines 1. This approach addresses both the symptomatic relief needed immediately and the long-term management of potential systemic complications associated with SSA antibody positivity.

Next Steps in Management
For a patient with elevated SSA (Sjögren's syndrome antigen) antibodies, the next steps in management involve a comprehensive approach to diagnose and treat Sjögren's syndrome. This includes:
- Conducting special investigations such as magnetic resonance imaging (MRI), nerve conduction studies, anti-ganglioside panel, and cerebrospinal fluid analysis, depending on the clinical presentation of the cases 2
- Performing tests such as Schirmer's test, tear breakup time, antinuclear antibodies (ANA) by immunofluorescent assay, ANA blot demonstrating the presence of anti-SSA (Ro) and/or anti-SSB (La) antibodies, and lip biopsy to confirm the diagnosis of Sjogren's syndrome 2
- Initiating treatment with steroids, followed by long-term immunosuppression with injection rituximab 2
- Managing sicca symptoms symptomatically, such as administering topical therapies like saliva substitutes and artificial tears 3
- Considering the use of biologic agents that target molecules and receptors involved in the aetiopathogenesis of primary Sjögren's syndrome, although the potential risks and benefits of these agents must be carefully considered 3
Systemic Manifestations
Systemic manifestations of Sjögren's syndrome, such as joint, muscle, lung, kidney, skin, or nervous system involvement, may require additional treatment approaches, including:
- Glucocorticoids, conventional DMARDs, or biologics (mostly rituximab) 4
- Intravenous immunoglobulins or plasma exchange in severe cases 4
- Immunomodulation to improve signs and symptoms and prevent progression, although the efficacy and safety of immunomodulation in primary Sjögren's syndrome need to be further assessed 5
Complications
Patients with elevated SSA antibodies are at risk of developing complications, such as lymphoma, and should be closely monitored for signs of systemic involvement, including:
