Rheum Flashcards
(29 cards)
Indications for urate-lowering therapy
- repeated attacks (≥2 per year)
- one attack in the setting of chronic kidney disease (CKD) of stage 2 or worse
- tophaceous deposits found on examination or imaging,
- history of urolithiasis
Jaccoud arthropathy
Hand deformities that look like RA but are reducible and no joint destruction (which would be erosions, periarticular osteopenia) present on X-ray
Can see in SLE, scleroderma, mixed connective tissue disease, Sjögren syndrome, recurrent rheumatic fever
lab testing for RA
anti-CCP, rheumatoid factor
Amyopathic dermatomyositis
Cutaneous findings of dermatomyositis without any muscle findings
Leflunomide
non biologic DMARD - for use in combo w biologic DMARD in pt w uncontrolled RA
watch for leflunomide hepatitis
Fibromyalgia Dx criteria
widespread pain, wakes unrefreshed, significant fatigue, and cognitive difficulties
last for 3+ mo
anti-Ro/SSA or anti La/SSB
Sjogren
SLE: photosensitive rash and neonatal SLE
anti-DS DNA
SLE: more severe disease, renal involvement
correlates with dz activity
hemochromatosis arthropathy
osteoarthritis-like
involves the second and third metacarpophalangeal (MCP) or wrist joints
anti-Jo
myositis: dermatomyositis and polymyositis Anti-synthetase syndrome: acute onset constitutional Sx myositis Raynaud's Mechanic's (hyperkeratotic) hands Arthritis (usually nonerosive) ILD = interstitial lung disease: nonspecific interstitial pneumonitis (most common) to usual interstitial pneumonia or bronchiolitis obliterans organizing pneumonia
tofacitinib
biologic DMARD, JAK inhibitor
major AE: dyslipidemia (can come on w/in 1mo), lymphopenia/neutropenia/anemia (usually a later effect)
Goal urate in gout
Features of ankylosing spondylitis
inflammatory back pain, primarily axial involvement, age of onset younger than 45 years, a positive HLA-B27, and a good response to an NSAID
Long term risk of familial mediterranean fever
AA amyloidosis
Colchicine decreases risk
Tx interstitial lung disease associated with diffuse cutaneous systemic sclerosis
cyclophosphamide
Psoriatic arthritis features
psoriasis, enthesitis, dactylitis, tenosynovitis, arthritis of the distal interphalangeal joints, asymmetric oligoarthritis, and spondylitis
Eosinophilic granulomatosis with polyangiities features
eosinophilia, migratory pulmonary infiltrates, purpuric skin rash, and mononeuritis multiplex in the setting of antecedent atopy
Tx polymyositis, dermatomyositis
prednisone 1mg/kg/d
If refractory or recurrent disease is noted, additional agents such as mycophenolate mofetil, intravenous immune globulin, rituximab, cyclophosphamide, or tumor necrosis factor (TNF)-α inhibitors can also be considered
Diffuse idiopathic skeletal hyperostosis
flowing osteophytes involving the anterolateral aspect of the thoracic spine at four or more contiguous vertebrae with preservation of the intervertebral disk space and the absence of apophyseal joint or sacroiliac inflammatory changes such as erosions.
diagnosis of acute gouty attack
INTRACELLULAR crystals
inclusion body myositis features
insidious onset
diffuse proximal and distal weakness, can by asymmetric
more common in men >50yo
mildly elevated or normal muscle enzymes
EMG w short-duration, small, low-amplitude polyphasic potentials; fibrillation potentials at rest; and bizarre, high-frequency, repetitive discharges
Tx RA
methotrexate -> anti-TNF alpha (etanercept, adalimumab, certolizumab, golimumab, infliximab) -> rituximab
Cryoglobulinemia
palpable purpura, glomerulonephritis (elevated serum creatinine, active urine sediment with cellular casts), mononeuritis, and skin infarctions of the fingers and ears
low C4, nml C3
RF positive w monoclonal paraprotein = RF itself
Screen for HCV
Milwaukee shoulder syndrome
basic calcium phosphate deposition
pain, stiffness, and swelling that tend to occur gradually over time, often with a preceding trauma or history of overuse on the affected side
predilection for women older than the age of 70 years
