What is Sjogren's Syndrome?

• A. An autoimmune disease affecting muscle tissue
• B. An autoimmune disease that dries up all lubricating fluids
• C. A viral infection causing inflammation
• D. A genetic disorder affecting immune cells

Answer: (B)

Sjogren's Syndrome is characterized as an autoimmune disease that primarily affects the body's ability to produce moisture, leading to dryness in various areas, most notably the eyes and mouth. This condition occurs when the immune system mistakenly attacks the glands that produce these lubricating fluids, such as saliva and tears. As a result, individuals with Sjogren's Syndrome often experience symptoms like dry mouth (xerostomia) and dry eyes (keratoconjunctivitis sicca).

Although Sjogren's can sometimes have additional systemic effects and may affect other parts of the body, the hallmark features of this syndrome revolve around the drying of mucosal surfaces due to impaired secretory function. This distinguishes it from conditions that might cause inflammation without necessarily leading to dryness or from genetic disorders that primarily involve immune cells without the specific symptom profile of fluid loss.
