Sjögren's syndrome (SS) is an autoimmune disease causing gland dryness and B-cell issues. It can lead to lymphoma and affect organs like lungs, kidneys, and bile ducts.

Area of Science:

  • Immunology
  • Rheumatology
  • Pathology

Background:

  • Sjögren's syndrome (SS) is a chronic autoimmune disorder.
  • It involves lymphocytic infiltration of exocrine glands, causing dryness.
  • It also features B-lymphocyte hyperreactivity, increasing lymphoma risk.

Purpose of the Study:

  • To detail the pathogenesis and clinical manifestations of Sjögren's syndrome.
  • To highlight extraglandular and pulmonary complications.
  • To emphasize the link between B-cell abnormalities and disease progression.

Main Methods:

  • Review of existing literature on Sjögren's syndrome.
  • Analysis of clinical presentations and pathological findings.
  • Characterization of autoimmune markers and B-cell activity.

Main Results:

  • SS primarily affects exocrine glands, leading to keratoconjunctivitis sicca and xerostomia.
  • Approximately 40% of patients develop extraglandular manifestations, including lymphoepithelial lesions and vasculitis.
  • Pulmonary involvement ranges from bronchitis sicca to lymphoproliferative diseases like B-cell non-Hodgkin's lymphoma.

Conclusions:

  • Sjögren's syndrome is a complex autoimmune disease with diverse systemic implications.
  • Extraglandular and pulmonary manifestations significantly impact patient prognosis.
  • Understanding B-cell hyperreactivity is crucial for managing SS and its associated malignancies.
