25
systemic features of RA
- Fatigue, fever, anemia - Elevated Acute phase reactants (ESR, CRP) - Constitutional symptoms: malaise, myalgia, depression
26
what is rheumatoid factor produced by
B cell in RA synovium
27
what is more sensitive to detecting erosions than X ray
CT
28
what do you need to monitor when giving methotrexate for RA
blood counts and liver and renal function
29
what disorder improves during pregnancy
RA
30
pts with RA have significantly increased mortality due to what
- CAD - HF due to endothelial damage from chronic inflammation - also increase in infection, renal disease, GI, and malignancy
31
what score on classification of RA is definite RA
6/10
32
what part of axial spine is affected by RA?
- C1-C2 | - be careful when intubating for anesthesia
33
if rheumatoid nodules present then what will always be + on serology
RF
34
Extra-Articular manifestations of RA?
- Skin: subcutaneous nodules; extensor surface of forearm - Pyroderma Grangrenosum: tender reddish purple papule; leads to necrotic, non healing ulcer - Rheumatoid Vasculitis: purpura, petechial, splinter hemorrhages, digital infarct - Heart: HF, pericarditis, CAD due to chronic endothelial inflammation - Lung: pleuritis most common, nodules, interstitial lung disease, Caplan syndrome (nodular densities after exposure to coal or silica dust, pulmonary fibrosis - Keratoconjunctivitis Sicca: secondary Sjogrens from RA
35
Tests for Sjogren
- Ro/SS-a, La/SS-B (both associated with solivary gland involvement - Schrimers test (filter paper under eyelids) - slit lamp exam
36
- RA - Splenomegaly - Neutropenia (<2000) - Fever - Anemia - thrombocytopenia - RF and anti-CCP +
Feltys syndrome
37
treatment of RA
- NSAID: pain relief, doesn't halt disease progression - Corticosteroids: low dose, Bridge or flare therapy - analgesics for pain controld - DMARDS: takes 2-6 months for max effect, methotrexate first line, don't give with pregnancy,
38
what antimalarial is useful in RA and can be used in pregnant patient
hydroxychloroquine
39
what are the anti-TNF biologic agents used in RA
- Etanercept - Infliximab - Adalimumab - Rituximab
40
what are the different spondyloarthropathies
- Ankylosing spondylitis - Reactive Arthritis - Psoriatic Arthritis - enteropathic arthritis
41
HLA for spondyloarthropathies
B27
42
describe the joint involvement in spondyloarthropathies
Asymmetric peripheral arthritis
43
Term: swelling of a finger or toe
Dactylitis
44
Term: enthesis
Site of ligamentous attachment to bone
45
Term: Enthesitis
inflammatory changes of the ligament, tendinous insertion into bone, or joint capsule
46
Term: inflammation of vertebrae
spondylitis
47
Term: anterior displacement of a vertebral body relative to the adjacent vertebral body below
Spondylolisthesis
48
Term: defect of the portion of bone b/t the inferior and superior articular process of vertebrae (pars interarticularis)
Spondylolysis
49
HLA for RA
DR4
50
RA M:F ratio | what about reactive spondyloarthropathies
- 1:3 - Ankylosing spondylitis is 3;1 - Reactive: 10:1
51
Reactive arthritis was formerly known as what
Reiter's syndome
52
clinical manifestations of ankylosing spondylitis
- Low back pain > 3 months - morning stiffness, improved with exercise, worse with rest - Fatigue, weight loss, and fever - Symmetrical SI joint pain (sacroiliitis); loss of mobility/flexibility; arthritis of hips - Tendonitis, planar fasciitis (Achilles-heel pain)/Enthesitis
53
Extra articular manifestation of ankylosing spondylitis
- Eye: IRITIS (not seen in RA) - photophobis, eye pain, blurred vision - Aortic insufficiency, aortic aneurysm - pulmonary fibrosis - IBD - Psoriasis
54
pts with ankylosing spondylitis have problems flexing forward . . what is the test for this called? What is the text for decreased chest expansion?
- Schober test | - Fabere test
55
what are syndesmophytes
- found in ankylosing spondylitis | - bridging of vertebrae (boney bridges cause ankyloses)
56
what are late complications of ankylosing spondylitis
- restrictive lung disease - compression fractures - cauda equine syndrome
57
age for Ankylosing spondylitis
below 40
58
Clinical manifestations of reactive arthritis
- young men - asymmetrical oligo-arthritis, lower extremeties (ankles, knees) - Enthesitis - Achilles tendon/plantar fasciitis - Dactylitis: sausage digit; finger or toe - SI pain, asymmetrical - urethritis, arthritis, conjunctivitis, mucocutaneous lesions (oral ulcers) - Skin: circunate balanitis (vesicles, ulcers on glans penis) - Keratoderma blennorrhagicum: painless eruption on palms/soles
59
how will joint manifestations of granulomatosis with polyangiitis differ from RA
usually involves large joints (hips, ankles, wrists) and usually spares the small joints of the hand -also C-anca
60
manifestations and labs of polymyalgia rheumatica
- stiffness and pain in shoulders, hips, and lower back - trouble combing hair, putting on coat, and rising from chair - markedly elevated ESRs
