29 Sjögren Syndrome Flashcards
Principal glands affected in Sjögren syndrome
Salivary and lacrimal
Gender predominance of pSS
Female
MC autoimmune disease present with SS
SLE or RA
T/F Parotid enlargement in SS is more frequent in adults
F, more frequent in children
MC presenting feature of SS among children
Parotitis
Characteristics of Sjogren parotitis
Uni- or bilateral, painful or painless, episodic or chronic
Juvenile recurrent parotitis compared to pSS
JRP usually presents at 3-6 years, younger than pSS
Stains used to demonstrate damaged ocular epithelium
Rose Bengal or lissamine green
Test that measures reflex tear production by using a folded strip of sterile filter paper at the margin of the eye, without anesthesia, and with the eye gently closed
Schirmer test
(+) Schirmer test
Wetting of ≤5mm in 5 minutes
(+) Rose Bengal score
≥4
Cells that infiltrate salivary glands in SS
Lymphocytes
Criteria for primary SS using the AECG classification criteria
1) 4/6 items + either histopath or serology (+) 2) 3/4 objective items (ocular, histopath, salivary gland involvement, autoAb)
Criteria for secondary SS using the AECG classification criteria
Ocular OR oral symptoms + any 2 ocular signs, histopath, or salivary gland involvement
3 objective features included in the ACR-SICCA classification criteria (must satisfy 2/3)
1) Anti-Ro and/or La or RF and ANA titer ≥1:320 2) Salivary gland biopsy exhibiting focal lymphocytic sialadenitis with a focus score of ≥1 focus/4mm2 3) Keratoconjunctivitis sicca with ocular staining ≥3; exclude other causes
ACR-EULAR classification criteria score for primary sjögren
≥4
ACR-EULAR criteria
1) Labial salivary gland with focal lymphocytic sialadenitis and focus score >1 2) Anti-Ro 3) Ocular staining 5 on at least 1 eye 4) Schirmmer ≤5mm/hr on at least 1 eye 5) Unstimulated whole saliva flow rate ≤0.1mL/min
Criteria needed for classification of jpSS according to proposed criteria
≥4
Extraglandular manifestations of Sjogren
fatigue
arthritis
arthralgia/myalgia
RP
T/F Renal involvement is common in Sjogren
F
A syndrome of purely sensory neuropathy said to be relatively unique to LS
Purely sensory neuropathy
T/F Among mothers of infants with NLE, SS is more common than SLE
F, as common
Primary pathological finding in SS
Lymphocytic infiltration of affected tissues
Focus scores are determined by
Counting # of lymphocytes ina. 4-mm2 area and classified on a scale from grade 0 (no abn) to 4 (>1 lymphoid nodule present)
