2. Sjögren's syndrome was in 1933 by
Swedish eye specialist Henrik Sjögren
• The condition causes antibodies to
attack the body's moisture-producing
glands, leading to dryness due to lack
of secretions.
• The illness most commonly affects the
eyes, mouth, salivary glands, lungs,
kidneys, skin and nervous system but
all organs of the body can be affected.
• In rare cases, complications from
Sjogren's syndrome can cause salivary
gland infections, kidney problems,
ulcers or pancreatitis.

4. • Venus Williams, 31, has spoken out about the autoimmune disease
that caused her to drop out of the U.S. Open yesterday minutes
before she was due to go on court.
• Miss Williams was diagnosed with Sjogren's syndrome two weeks ago
- after years of being misdiagnosed with other
conditions.
• 'For years I felt that I didn't have enough stamina and then,
four years ago, I felt like I was not getting enough air but I
was diagnosed with exercise-induced asthma,' she said.
•
'The medicine for asthma never worked.'
• Eventually, as her symptoms progressed doctors got to the bottom of
the problem. The athlete now suffers from fatigue, swollen joints, dry
eyes, dry mouth and heavy limbs.

5. Sjögren's Syndrome
• A chronic, slowly progressive autoimmune
disease characterized by lymphocytic
infiltration of the exocrine glands resulting in
xerostomia and dry eyes.
• 1/3 have systemic manifestations
• Few develop lymphoma
• female-to-male ratio, 9:1
6. 2 Forms
• Primary Sjögren's
syndrome:
The disease presents
alone
• Secondary Sjögren's :
Asso. with other
autoimmune diseases
–RA
–SLE
–Scleroderma
–Mixed CT disease
–Primary biliary cirrhosis
–Vasculitis
–Chronic active hepatitis
7. Sjögren syndrome: Etiopathology
• Etiology -not well understood
• Findings suggest an ongoing interaction between
the innate and acquired immune systems
• Lymphocytic (T,B) infiltration of exocrine glands
+
• B lymphocyte hyper-reactivity
8. Sjögren syndrome: Etiopathology
Glandular epith cells express MHC class II mols
• Inherited susceptibility+ exo /endogenous antigens
• Trigger a self-perpetuating inflammatory response
• Continuing presence of active interferon pathways
suggest ongoing activation of the innate immune
system
9. Sjogren’s: Clinical Manifestation
The majority have symptoms related to
diminished lacrimal and salivary gland
function.
In most, the primary syndrome runs a slow and
benign course over 8 to 10 yrs.
10. Sjogren’s: Oral Manifestations
• Dryness (xerostomia), burning sensation
• Difficulty in swallowing dry food
• Inability to speak continuously
• Dental caries
• Problems in wearing dentures
Physical examination:
• Dry, reddened, sticky mucosa
• Atrophy of tongue
• Saliva not expressible/ cloudy
• Enlargement of salivary glands - 2/3 of primary SS
- Uncommon in secondary
11. Dryness of the mouth - xerostomia
Deep red tongue
Dental caries common
13. Sjögren’s syndrome and a L parotid mass.
Biopsy: B-cell lymphoma of mucosal lymphoid tissue
14. Sjogren’s: Ocular manifestations
Due to the destruction of corneal and bulbar
conjunctival epithelium, defined as
keratoconjunctivitis sicca
• A sandy/ gritty feeling under eyelids
• Burning
• Accumulation of thick secretions at inner canthi
• Decreased tearing, redness, itching,
• eye fatigue, increased photosensitivity
15. Sjogren’s: Clinical Manifestations
Other exocrine glands
• Resp : secretions dry nose, throat, and
xerotrachea
• GIT: Esophageal mucosal atrophy, atrophic
gastritis, and subclinical pancreatitis
• GUT: Dyspareunia and dry skin
16. Sjogren’s: Clinical Manifestation
Medications that cause similar symptoms
• Antidepressants
• Anticholinergics
• Beta blockers
• Diuretics
• Antihistamines
• Women on HRT
• Anxiety
17. Sjogren’s: Clinical Manifestations
Extra Glandular:
• Easy fatigability, low-grade fever, Raynaud‘s,
myalgias, and arthralgias
• Joints: Non-erosive arthritis
• Pulmonary : Dry cough (small airway disease)
• Renal: interstitial nephritis, acidosis and
nephrocalcinosis. Glomerulonephritis rare (SLE
overlaps).
• Vasculitis -purpura, recurrent urticaria, skin
ulcerations, GLN, and mononeuritis multiplex.
• SN hearing loss, any focal deficits
22. Sjogren’s Investigations: Must exclude
• Hepatitis C virus infection should be ruled out
since, apart from serologic tests, the
clinicopathologic picture is almost identical to
that of Sjögren's syndrome.
• HIV infection
• Sarcoidosis
23. Sjogren’s: Treatment
• Artificial tears, Rx -corneal ulcerations
• Avoid drugs that secretions (diuretics, anti HTs,
anticholinergics & antidepressants)
• Xerostomia: Best replacement - water
• Vaginal dryness: Propionic acid gels
• Secretagogues: Oral Pilocarpine / Cevimeline
• Arthralgias : HCQ
• RTA: Oral Soda bicarb
• Systemic vasculitis: Steroids,
immunosuppressives, M Abs
• High-grade lymphomas: Chemo (CHOP) + M Abs
