Sjogren's Syndrome Flashcards
In general
Chronic AI dz affecting salivary and lacrimal exocrine glands
1/2 primary and 1/2 secondary
Patho
From stimulation of immune systems
Lymphocytes infiltrate glandular and extra glandular sites
Apoptosis and migrations of Ro-60 (SSA) and La (SSB) to cell surface
Induces autoAB formaiton
Will have ANA, anti-Ro/SSa and anti-La/SSB
Apoptosis of ductal and acinar epithelial cells along with interstitial firboriss dimiinishes glandular secretions
Epidemiology
Middle aged women
CM
Major are keratoconjunctivitis sicca and xerostomia
Most have slow course
Trouble swalling dry food, debtal caries, or change in taste
Dry, red, sticky oral musoca with atorphy of papillae on the tongue
Enlargment of salivary glands
Dilation of bulbar ocnjunctival vessels
1/3 will have myaglia, arthralgia or Raynauds
50% have another rheumatic dz
Complications
Lymphoma
MALT of the salivary gland or DLBCL in surrounding LNs
Dx
Suspect if dry eyes, mouth, parotid enlargmeent, and increase in dental caries
hyperglobulinemia (IOgG)
ANA, anti-Ro/SSa, anti-La, RF
Ro and La are big ones
May have anemia or increased ESR
Refer to ophto
Salivary biopsy - focal lymphoid infiltration with germinal centers OR interstial fibrosis and acinar atrophy
Tx
Sx relief
Hydration
Articifical tear preps
