- Historical background 1882 Leber described filamentary
keratitis 1888 Mikulicz described a patient with bilateral lacrimal
and parotid enlargement. 1933 Henrik Sjgren described the
association of filamentary keratitis with arthritis. 1953 Morgan
and Castleman noted the commonality between the glandular
enlargement described by Mikulicz and the keratitis described by
Sjgren Sjgren's syndrome (SS)

- Historical background, ctd: 1980 Talal introduced the term
autoimmune exocrinopathy Skopouli and Moutsopoulos introduced the
term autoimmune epitheliitis

4 of the 6 criteria, must include either item IV (Histopathology)
or VI (Autoantibodies) Any 3 of the 4 objective criteria (III, IV,
V, VI) Secondary Sjgrens syndrome diagnosis: Well-defined major
connective tissue disease One symptom (I or II) plus 2 of the 3
objective criteria (III, IV and V) is indicative of secondary
SS.

Hallmarks: Dry eyes Dry mouth Autoimmune disorders: Rheumatoid
arthritis SLE Scleroderma
- Slide 21
- Proposed SS classification criteria 2012: at least 2 of the
following 3 objective features: 1. Positive serum anti-SSA/Ro
and/or anti-SSB/La or (positive rheumatoid factor and ANA titer
1:320) 2. Labial salivary gland biopsy exhibiting focal lymphocytic
sialadenitis with a focus score 1 focus/4 mm2 3.
Keratoconjunctivitis sicca with ocular staining score 3 (assuming
that individual is not currently using daily eye drops for glaucoma
and has not had corneal surgery or cosmetic eyelid surgery in the
last 5 years)
- Slide 22
- Proposed SS classification criteria 2012: Prior diagnosis of
any of the following conditions would exclude participation in SS
studies or therapeutic trials because of overlapping clinical
features or interference with criteria tests: History of head and

detectable salivary flow 55% with dry skin at presentation. Ss pts
also have increased recurrent sinusitis, chronic cough, recurrent
oral candidiasis, indigestion, constipation, dysphagia and
dysgeusia

dysfunction. SS is 10 times higher in autoimmune thyroiditis pts.
Raynauds in 13% of SS Over half of SS pts will have subclinical
muscle inflammation. Over half will have arthralgia. Depression is
very common in SS pts. Fatigue if profound, significantly limiting
the activities of more than half the patients Voulgarellis M&

- Sjogrens Syndrome Clinical Pearls High risk of lymphoma
development and therefore high mortality rates : 1. Severe
involvement of exocrine glands 2. Vasculitis 3. Low C4levels 4.
Cryoglobulinemia Malignant lymphoma may be at 44 times higher than
the general population.
- Slide 30
- Sjogrens Syndrome Clinical Pearls pSS associated lymphomas:
Often develop in mucosal locations where pSS is active Mostly
B-cell non-Hodgkin lymphomas (NHL) with a predominance of the low
grade, marginal zone MALT histological type. Royer, B. et al.
Lymphomas in patients with Sjgren's syndrome are marginal zone
B-cell neoplasms, arise in diverse extranodal and nodal sites, and
are not associated with viruses. Blood90, 766775 (1997).

- Sjogrens syndrome Clinical pearls: Vascuiltis One of the more
common extragladular manifestations. Approximately half with
subcutaneous vasculitis have only one episode. Associated with more
severe SS disease. Therapy for vasculitis: steroids. IVIG may be
affective Scofield RH.Curr Rheum report.2011

pearls: Neuropathy Neurological manifestations in PSS varies from
10 to 60%. Sensory neuropathy is the most common. Patients with
neuropathy are more likely to have palpable purpura, vasculitis,
cryoglobulinemia, monoclonal gammopathy, and lymphoma. Usually a
late event associated with systemic disease. Mechanism is unclear

- Sjogrens associated neuropathy Sjogren, 1935: Case 9: Bilateral
chronic otitis media; Bilateral VII nerve neuritis. In my previous
work, I noticed that decreased sensation of the conjunctiva and the
cornea sometimes occurs. This variable and very inconstant symptom
results from the local histological modifications and must not be
considered as a trigeminal nerve involvement. Other sensory
impairment in the territory of the trigeminal nerve was not
observed.
- Slide 35
- Sjogrens associated neuropathy Sheldon,1939: Case report: there
have developed during the same period: 1. Mental changes, for which
she has been a voluntary inmate in the Staffordshire County Asylum.
The symptoms are mostly of a delusional type and are cheerful in
character. 2. Epileptic fits.
- Slide 36
- Sjogrens associated neuropathy Weber,1945: described nonocular
features of SS in several case reports, 2 of them with nervous
system involvement Coverdale,1948: described patients with SS "with
unusual' constitutional features," one of whom had neurological
manifestations: Mr A... aged 68 years... made no complaint of these
disabilities (xerostomia and xerophthalmia) until a few months ago
when he had a cerebral hemorrhage with hemiplegia and his eyes
became worse.

- Dendritic Cells: Found in salivary glands of patients Increased

- Slide 60
- Pathogenesis of Sjogrens syndrome T cells: Increased Th17 cells
in salivary glands Potential defect in Tregs( as disease advances
numbers of Treg drops) T cell cytokines: TH1 cytokines dominate in
early SS disease stage. TH2 cytokines dominate in later SS disease
stage Upregulation of IL6 results in Th17 cells forming germinal
centers in salivary glands
- Slide 61
- Pathogenesis of Sjogrens syndrome B cells: Migrate to the
salivary gland due to increased cytokines and chemo attractants.
Formation of ectopic germinal centers. Increased activation of B
cells. Autoantibodies: Hypergammaglobulinemia Production of
anti-RF, anti-Ro(SSA),and/or anti-La(SSB) Blys(BAFF): B cell
stimulator Upregulated expression Plays a key role in development
of germinal centers
- Slide 62
- Autoantibodies 80-90% of primary SS pts will have at least one
of anti-Ro, anti-La and/or RF. Anti Ro/La are linked with : 1.
Earlier disease onset 2. Increased disease severity 3. Longer
disease duration 4. Extraglandular involvement.

quite modest Between 1986 and 2010, 1,791 publications in Medline

controlled trials and 19 are prospective cohort studies. Majority
focus on symptoms of dry eyes or dry mouth. Large trials also
