Sjogren's Syndrome
Sjorgren's Syndrome is an autoimmune condition characterised by decreased lacrimal and salivary gland secretion, leading to dry eyes and mouth. It's due to a lymphocyte-mediated autoimmune destruction (type IV hypersensitivity) of minor salivary and lacrimal glands, leading to atrophy and fibrosis.
Types:
Primary – Occurs alone
Secondary – Occurs related to SLE or RA
Complications
Eye – Reduced tear secretion (causing dry, gritty eyes that may appear red)
Superimposed bacterial conjunctivitis often occurs
Mouth – Dry mouth (causing difficulty talking or swallowing), Swollen parotids
Cavities and candida infection often occurs
Vagina – Dryness, Candida infection, Sexual dysfunction
Patients here are at a much higher risk of Lymphoma, therefore patients with new/changing lymphadenopathy should be investigated promptly.
Investigations
CRP/ESR, Anti-Ro, Anti-La
Schirmer’s Test - Demonstrates reduced tear secretion - Paper put under lower eyelid. After 5 minutes, the distance that becomes moist is measured
A result of < 10mm (NR >15mm) is significant
Management
Symptomatic relief:
Dry eyes - Artificial tears and saliva
Dry mouth - Artificial saliva, hydration, and good dental hygiene
Vaginal dryness - Topical lubricants
