Sjögren's syndrome.

Area of Science:

• Immunology
• Rheumatology
• Pathology

Background:

• Sjögren's syndrome is a chronic autoimmune disorder targeting exocrine glands, primarily salivary and lacrimal glands.
• This leads to characteristic dryness of the mouth and eyes, impacting quality of life.
• The condition can be primary or secondary to other autoimmune diseases like rheumatoid arthritis.

Purpose of the Study:

• To review the diagnostic criteria and therapeutic strategies for Sjögren's syndrome.
• To highlight the challenges in diagnosing and managing patients with overlapping symptoms like fibromyalgia.
• To discuss the molecular basis of this tissue-specific autoimmune process.

Main Methods:

• Review of international consensus diagnostic criteria.
• Analysis of therapeutic approaches, including topical, systemic anti-inflammatory, and disease-modifying agents.
• Examination of diagnostic challenges, particularly in patients with fibromyalgia-like symptoms.

Main Results:

• New diagnostic criteria emphasize objective signs of dryness, characteristic minor salivary gland biopsy findings, or specific autoantibodies (e.g., anti-SS-A).
• Therapies range from topical agents for symptom relief to systemic treatments for extraglandular manifestations.
• Fibromyalgia symptoms alongside dryness present a diagnostic and therapeutic challenge.

Conclusions:

• Sjögren's syndrome diagnosis requires objective evidence and exclusion of certain infections.
• Comprehensive management addresses both glandular and extraglandular symptoms.
• Further research is needed for complex cases, especially those with fibromyalgia overlap.
