Summary
Sjögren's syndrome (SS) is an autoimmune disorder affecting exocrine glands, often involving other body sites and potentially leading to lymphoma. Diagnosis requires careful consideration of various conditions, and treatment remains symptomatic.
Area of Science:
- Rheumatology
- Immunology
- Pathology
Background:
- Sjögren's syndrome (SS) is a chronic autoimmune disorder targeting exocrine glands.
- It is characterized by lymphocytic infiltration and autoantibodies (Ro/SSA, La/SSB).
- Extraglandular involvement occurs in one-third of patients, with a 5% risk of B-cell lymphoma.
Purpose of the Study:
- To present a practical diagnostic algorithm for Sjögren's syndrome.
- To highlight the differential diagnosis of SS, including primary and secondary forms.
- To underscore the empirical and symptomatic nature of current treatments.
Main Methods:
- Sequential application of validated European classification criteria for SS.
- Consideration of differential diagnoses such as drug effects, sarcoidosis, and infections.
- Evaluation of extraglandular manifestations for treatment decisions.
Main Results:
- A diagnostic algorithm for SS based on European criteria is provided.
- Differential diagnosis encompasses a wide range of conditions mimicking SS.
- Treatment decisions are guided by the severity of extraglandular disease.
Conclusions:
- Accurate diagnosis of SS requires multidisciplinary input and consideration of numerous differential diagnoses.
- The clinical spectrum of SS is broad, encompassing glandular and extraglandular manifestations.
- Current therapeutic strategies for SS are largely symptomatic and empirical, focusing on extraglandular disease severity.
