potential genetic predisposition, low oestrogen risk, dysregulation of inflammatory processes
EBV association
what is the timeline of sjogrens onset
patient has genetic predisposition and then environmental factors occur which triggers the disease
what are the consequences of sjogrens
gradual loss of salivary gland tissue through inflammatory destruction
enlargement of major salivary glands
increased lymphoma risk
oral and ocular effects of loss of moisture
what is the immunopathology of sjogrens
lymphocytic foci (multiple T lymphocytes in the one place)
what is the AECG criteria for sjogrens
4 of:
- dry eyes/mouth
-autoantibody findings
-imaging findings
- radionucleotide assessment
- histopathology
what is the ACR-EULAR criteria for sjogrens
histopathology
autoantibody findings
dry mouth
ultrasound
must have either histology or serology
what is the snowstorm appearance on ultrasounds caused by
holes caused by loss of acini
what are the oral symptoms of sjogrens
daily feeling of dry mouth for >3months
recurrent swelling of salivary glands as an adult
frequently drink liquid to aid swallowing dry foods
what are the ocular symptoms of sjogrens
persistent dry eyes for >3 months
