Sjogrens Syndrome Flashcards
What is Sjögren’s syndrome?
- Autoimmune disorder
- There will be destructions of exocrine glands
*will be dryness - Sicca syndrome (isolated dry eyes and salivary glands)
What is the general population of Sjogren syndrome and prevalence?
- Rare 1% of the population
- Can occur in 10-15% of RA patients
- 9 to 1 F>M
*in the 30’s and 50’s most occur between 40-60
What will be at an increased risk if a patient has SS?
Increased risk of lymphomas
What causes Sjorgrens ?
- A combination of genetic and environmental factors
- Genetics:
*HLA-DR correlates with +ANA and +Anti-SS-a (Ro) antibody
What are the clinical manifestations of SS?
- Xerophtalmia
- Keratoconjunctivitis sicca
- Xerostomia
- Parotid enlargement
What can be used for SS diagnostic tests?
- Lip biopsy
- Schirmer test (seeing the amount of tears present)
- Labs
*RF (+70%) and ANA (+95%)
*SS-A/Ro (+) (most helpful)
*SS-B/La (+) (most helpful)
*CBC/diff (anemia)
What are the neck and head manifestations of SS?
- 80% complaints of xerostomia
- Difficulty chewing
- Dysphasia
- Taste changes
- Fissures of the tongue and lips
- Increased dental caries
- Oral candidiasis
- Salivary gland enlargement
Non-Salivary gland disease Ddx
- Drugs
*BP and cardiac - Acute anxiety and depression
- Mouth breathing
- Central lesions
*MS
*Alzheimers
Salivary gland Ddx
- Hepatitis C
- Sarcoidosis
- Fatty infiltrate of gland (change to the gland itself)
- HIV disease

*corneal abrasions
What other manifestations can occur due to SS?
- Skin vasculitis
- Fatigue
- Cognitive loss
- Skin-dry
- Lung- interstitial pneumonitis
- Cardiac pulmonary hypertension
What is the titer of ANA in SS?
1:80
*80 dilutions took place and you can still see the ANA
What is the gold standard of testing for SS?
Lip biopsy
*still can be misread by pathologists
What are the labs that you should order when suspecting SS?
- CBC
- ESR, CRP
- Chemistry panel
- UA
- Serologies
*ANA, Anti-SSA/Ro, anti-SSB/La, Rf as initial screen
*test for vitamin A deficiency - Minor salivary gland biopsy
*to confirm dx of SS in patients lacking or low titer anti-SSA/Ro antibodies
What is the treatment of SS?
- Oral fluid intake
- Salvia substitutes
- Artificial tears
