Connective Tissue Disorders And Vasculitis - Dr. McGowen Flashcards
SLE prevalence and what is it
multisystem disorder
= F
= black and latino
= autoimmune to nuclear Ags (TYPE 3 hypersensitivity)
SLE SX you can see
- fever
- malar rash, photosensitivity
- arthritis inflammatory
- Pericarditis (pain laying supine, ST elevation diffuse, crushing sharp CP)
- Libman sacks endocarditits
- thrombosis
SLE DX how
- dsDNA ABs
- Sm (Smith) ABs
- low C3 / C4
SLE TX
- avoid sun
- NSAIDs for pain
- Glucocorticoids
- Hydroxychloroquine
SLE management for risks and prevention ** 6
- SLE increases atheroscleorosis : minimize risk
- no smoking, obesity, htn, hypercholestemia, exercise
- flu vaccine
- pneumonococcal vaccine every 5 years
- higher malignancy risk so screen
- glucocorticoid use = minitor for avascular necrosis in bones
Early stage SLE reason for death
- infections (opportunistic infections from immunosuppressive TX)
- Kidney + CNS disease *
later stage SLE reason for death
- Accelerated atherosclerosis from chronic inflammation (%x MI risk)
Anti-Phospholipid AB syndrome (APS) : secondary vs primary
primary : APS ABs only
secondary : APS and SLE (1/3 patients with SLE have APS
Anti-Phospholipid AB syndrome (APS) :
AB serology
- Anti- Cardiolipin (aCL)
- Lupus anticoagulant (LA)
- Beta 2 glycoprotein 1 (anti-B2 GPI)
= all 3 testes 2 times at least 12 weeks after
Anti-Phospholipid AB syndrome (APS) :
what are risks and what happens
- venous and arterial thrombosis
- miscarriage
= prolong PTT clotting time not reversed by plasma (plt free)
aCL features
+ in APS
= can cause false + syphilis test in non-treponemal test
APS tx
