Johnston Flashcards
ESR rises with age and are higher in women and can be used to monitor disease activity, especially in what diseases
- polymyalgia rheumatic
- giant cell arteritis
what marker of inflammation is used for assessment of disease activity, synthesized in liver, increased by proinflammatory cytokines and can activate complement and promote phagocytosis
CRP
what level of CR is inflammatory
greater than 8
this is an autoantibody that targets the Fc portion of IgG?
What type of antibody is it most commonly
- RF
- IgM
Rheumatoid factor and RA
- 70-80% of patients
- 100% with “nodular” RA
- RF is found in many other diseases
Anti CCP plus + RF
99.5% specificity for RA
Homogenous pattern immunofluorescense for ANA? Rim pattern? Anti Sm antibodies? Speckled anti SSA/B? Anticentromere?
- Drug induced (procainamide, hydralazine Dilantin)
- Anti DS DNA
- SLE
- Sjogren
- Scleroderma
the malar rash in SLE spares what
nasolabial folds
arthritis in SLE
-2 or more peripheral joints
hematologic finding in SLE
basically every down except reticulocytes are up
what can give a false positibe RPR (test for syphilis)
SLE
what is the Jones Criteria for Rheumatic Fever?
- Carditis
- Joint involvement (arthritis)
- Chorea
- Erythema Marginatum
- Subcutaneous nodules
- Evidence of preceding Strep infection
what level of uric acid is hyperuricemia?
> 6.8 mg/dl
what are tophi
nodular deposits of monosodium urate crystals in the skin from gout
what is podagra
acute onset, monoarticular, often 1st MTP joint affected by gout
Treatment of acute Gout
- NSAIDs
- Colchicine
- Steroids
chronic management of gout
- Xanthine oxidase inhibitor (uricouric drug)
- Probenecid: block tubular resorption of urate and increased uric acid excretion
what imaging is sensitive for soft tissue abnormalities (synovitis, tendonitis, bursitis) and erosions
US
what imaging for RA symmetrical involvement of MCP, periarticular osteopenia erosions
Radiography
MRI is good for what?
downfalls?
- spine, SI, synovitis, tenosynovitis, erosions
- Gadolinium contrast taken up in inflamed synovium (thickened pannus) . . IV gadolinium can cause nephrogenic systemic fibrosis in patient with kidney disease
what is Enthesopathy
-inflammation of ligaments and tendons where they insert into bony attachments . .hallmark for reactive arthritis
- 1 joint involved?
- 3 or less?
- 5 or less
- 6 or more?
- arthritis
- Oligoarthritis
- Pauciarthritis
- Polyarthritis
what hand joints are spared in RA
DIPs
DIPs involved in OA . .what nodes
