Sjorgens Flashcards
Define Sjorgens syndrome
Inflamation (AID) and destruction of exocrine glands (saliva, tears, lacrimal etc)
Lymphocyte infiltrate the glands, hyperreactivity of the B cells to nuclear Ab, but different from SLE
Few relations with genetics it seems
Risk factors:
HLA DR3
Female
SLE/RA
Signs and Sx of Sjorgens syndrome
Swollen parotid glands,
dry eyes (very red, patients will say)
dry tongue (no saliva)
large submandibular mouths
dry eyes: keratoconjunctivitis sicca
dry mouth
vaginal dryness
arthralgia
Raynaud’s, myalgia
sensory polyneuropathy
recurrent episodes of parotitis
renal tubular acidosis (usually subclinical)
Investigations of Sjorgens syndrome
Positive to ANA - especially anti-Ro and anti-La
also Rheumathoid factor positive
Lip gland biopsy-foci of lymphocyte infiltrates
anti-La (SSB) antibodies in 30% of patients with PSS
Schirmer’s test: filter paper near conjunctival sac to measure tear formation
histology: focal lymphocytic infiltration
also: hypergammaglobulinaemia, low C4
Management of Sjorgens syndrome
Not really imminosupressive
tear substitute,
saliva substitute,
rarely pilocarpine
complications:
risk of increased lymphoma
