Sjögren syndrome (SS) diagnosis is challenging due to overlapping symptoms and autoantibodies. Research highlights immune factors and potential therapies for this autoimmune disease.

Area of Science:

  • Rheumatology
  • Immunology
  • Pathogenesis of autoimmune diseases

Background:

  • Sjögren syndrome (SS) is the second most common autoimmune rheumatic disease, characterized by dry eyes and mouth due to immune cell infiltration of glands.
  • Diagnostic challenges arise from vague symptoms, common autoantibodies in the general population, and difficulties distinguishing SS from other conditions like fibromyalgia.
  • Genetic and environmental factors contribute to SS pathogenesis, with no single factor identified in most patients.

Purpose of the Study:

  • To review the diagnostic complexities and current understanding of Sjögren syndrome (SS) pathogenesis.
  • To discuss the role of immune factors, such as cytokines and autoantibodies, in glandular dysfunction.
  • To outline emerging and established therapeutic strategies for managing SS symptoms.

Main Methods:

  • Literature review of Sjögren syndrome (SS) diagnosis, pathogenesis, and treatment.
  • Analysis of diagnostic challenges including serological markers and biopsy interpretation.
  • Examination of the role of specific autoantibodies and immune mediators.

Main Results:

  • Minor salivary gland biopsies require experienced interpretation to differentiate SS from non-specific sialadenitis.
  • Autoantibodies, including those against the muscarinic M3 receptor, are frequently found in SS patients and implicated in reduced secretory function.
  • SS-like syndromes associated with HTLV-1 and hepatitis C offer insights into disease mechanisms.

Conclusions:

  • Effective management of SS requires addressing diagnostic complexities and understanding the multifactorial nature of the disease.
  • Therapeutic advancements include muscarinic receptor agonists for salivary secretion and topical treatments for ocular dryness.
  • Further research into genetic and environmental factors is crucial for developing targeted therapies.
