Vasculitis Flashcards
define vasculitis
this is inflammation of the blood vessels
what is vasculitis associated with
ischaemia
necrosis
organ inflammation
define primary vasculitis
results from inflammatory response that targets the vessel walls
define secondary vasculitis
triggered by infection, drug, toxin or predisposing condition
presentation of vasculitis
systemic= fever, malaise, weight loss
bruit, claudication and high BP
organ involvement, especially kidneys as asymptomatic
diagnosis of vasculitis
- urinalysis for kidneys/glomerular nephritis
- ESR/plasma viscosity/ CRP/ complement reduced (C3/4 immune complex forming)
- temporal artery biopsy or any affected area to detect granulomas
- immunofluorescence for ANCA
- antibodies (anti-PR3- GPA and anto-mpo- EGPA)
- CXR (granulomas with a caveatting centre)
CT of abdomen
management of vasculitis
prednisolone (high dose steroids)
immunosuppressants e.g. cyclophosphamide (FIRST LINE) methotrexate, azathioprine, rituximab
two types of large vessels vasculitis
takayasu arteritis (TA) giant cell arteritis (GCA)
define takayasu arteritis
inflammation of all the large vessels, seen in developing parts of the world
presentation of giant cell arteritis
loss of sight/vision change
tenderness of scalp
prominent temporal arteries and loss of pulse due to thickened wall
diagnosis of giant cell arteritis
biopsy
management of giant cell arteritis
steroids
what is small vessels vasculitis divided into?
ANCA positive and negative
four examples of small vessel vasculitis
- granulomatosis with polyangiitis (GPA)
- eosinophilic granulomatosis with polyangiitis (EGPA)
- microscopic polyangiitis
- HSP
define granulomatosis with polyangiitis
inflammation of the respiratory tract
