diffuse SSc | anti-SCl-70 is positive
27
what causes organ damage in Systemic sclerosis?
excessive calcification deposits - renal and lung mainly!! pulmonary hypertension is serious - 12% of SSc deaths.

facial features of systemic sclerosis?
tightening of the skin of the nose = beaking tight lips telangiectasia (T of CREST)
29
in SSc what is the skin like before it goes atrophic?
oedematous to begin with. | in hands - almost always have Reynaulds early on!!
30
what is anti-Jo1 positive for? a) SLE? b) MCTD? c) anti phospholipid syndrome? d) myositis?
D = myositis. only
31
what type of immune response is SLE?
type 3 - complexes attack basement membranes
32
pattern of psoriatic arthritis
asymmetrical elbow,wrists,palms knees,ankles, toes
33
development of RA.. 1. first joints affected: 2 then: 3. in severe disease:
1 - small joints of hands and feet, not DIP 2- large joints - knees shoulders elbows 3 - cervical spine, risk of A.A subluxation.
34
extra-articular features of RA - elbows - lungs - CVS - eyes
- rheumatoid nodules - pulm nodules. effusions and fibrosis - worsens CVS health - common eg uveitis
35
what DAS 28 score do you need to be able to have biologics?
over 5.1 !!! (severe)
36
is a DAS 28 score of 3.7 in the low or moderate category?
MODERATE (3.3 - 5.1)
37
is a DAS 28 score of 2.9 in remission??
NO in remission is < 2.6 low is 2.6 -- 3.2
38
are DMARDS recommended for ankylosing spondylitis?
not for treating spinal disease - only if there is peripheral joint inflammation.
39
hand features of psoriatic arthritis?
pitting onycholysis - lifting off the nailbed. dactylitis also
40
Tx for psoriatic arthritis
DMARDs are good. antiTNF if unresponsive potentially replacement
41
pattern of enteropathic arthritis
asymmetrical large joints - spine included.
42
treatment of reactive arthritis 1 - acute 2 - chronic
1 - treat the infection. symptomatic relief (including steroid injections) 2 - DMARDS sometimes used
43
``` treatment of sjogrens 1 - eyes 2- mouth 3- teeth 4- arthralgia 5- fatigue 6 - ILD ```
``` 1- eyedrops 2- saliva stimulation / replacement 3- very good dental care 4 - hydroxychloroquine 5- hydroxychloroquine 6- other immunosuppression. ```
44
what is a spinal complication of RA?
atlano-axial subluxation
45
how do you investigate RA?
1. autoantibodies - RFactor and anti CCP 2. inflammatory markers - raised CRP, PV and ESR 3. X ray - early signs are uncommon, look for peri-articular osteopenia and soft tissue swelling
46
how do you treat RA?
1. most importantly, start DMARDS (methotrexate) within 3 months of onset 2. consider NSAIDS and other steroids for pain relief 3. if unresponsive - antiTNF biologics (if DAS 28 score is over 5.1 as severe)
47
what are the potential side effects of RA treatment?
immunosuppression - infection steroids - lots, inc osteoporosis, weight gain biologics - reactivation of latent TB
48
what is HLA B27 ?
a marker of seronegative arthropathies
49
age and gender of typical ankylosing spondylitis patient?
male (3:1) and 20-40 years old
50
in ank spon, in addition to uveitis, amyloidosis and pulmonary fibrosis, what else occurs?
aortitis
51
treatment of ank spondylitis
physio NSAIDS anti TNF peripheral arthritis adittionally --> give DMARDS
52
1st and 2nd line Tx for psoriatic arthrisis?
1. DMARDS | 2. anti TNF
53
3 features of Reiters?
reactive arthriss… 1. uvieitis 2. urethritis 3. arthritis
54
treatment of acute reactive arthritis?
just treat the underlying infection and give steroids for symptomatic relief DMARDS ONLY FOR CHRONIC !!!
55
how do you treat someone with raynauds caused by systemic sclerosis?
calcium channel blockers
56
how do you treat someone who's renal system is affected by systemic sclerosis, causing hypertension?
ACE inhibitors
57
how do you treat someone with pulmonary fibrosis caused by systemic sclerosis?
immunosuppression, usually with cyclophosphamide.
58
what is the criteria for a diagnosis of systemic sclerosis/
1 major and 2 minor features
59
in systemic sclerosis, WHERE are the.... - "major" features? - "minor" features??
Major: skin sclerosis that affects the arms, face, and/or neck Minor: sclerodactyly +atrophy of the fingertips and bilateral lung fibrosis.
60
causes of gout? (3)
build up of uric acid 1. poor renal excretion - made worse by renal failure or diuretics 2. excessive intake via red meat, wine 3. may be a genetic cause
61
what is podagra?
gout in the 1st MTP joint
62
2nd and 3rd most common gout sites?
ankle and knee
63
Tx of acute gout?
NSAIDs, corticosteroids, opioid analgesics and colchicine for patients who cannot tolerate NSAID
64
cause of pseudogout?
build up of calcium pyrophosphate
65
what is chondrocalcinosis?
a term for calcium pyrophosphate deposition (pseudogout) | without inflammation
66
S/E of allopurinol in psueudogout
trick question - allopurinol isn't used for pseudogout, there is no prophylaxis for it at all
67
which is postivive / negative birefringent.... - gout - pesudogout
gout= negative pseudo = positive
68
what cancer is predisposed with sjogrens?
lymphoma
69
what is NOT a cause of chest pain in SLE? - a. Pleurisy b. Myocardial infarction c. Pulmonary embolus d. Pericarditis e. Pneumothorax
E = pneumothorax
70
what heart defect can occur in seronegative arthropathies?
aortic valve incompetence
71
what do you expect to find on aspiration of a reactive arthritis?
nothing!! sterile = reactive positive for microorg = septic!!
72
s/e of corticosteroids a. Wheeze b. Constipation c. Dyspepsia d. Renal impairment e. Increased cardiovascular risk
C,D and E | constipation - more common in opiates
73
6 "A"s of ankylosing spondylitis | head to toe
``` anterior uveitis axial arthritis apical fibrosis aortic regurgitation amyloidosis achilles tendonitis ```
74
SLE treatment - skin - arthropathy + organs - severe organ - unresponsive
skin = topical steroids, NSAIDS arthropathy/ organs - Azathioprine / short time steroids severe organ - IV steroids, cyclophosphamide unresponsive - IV Immunoglobulins / antiTNFa Ritixumab

treatment of Anti phospholipid syndrome? | when #preggers ?
lifetime of anticoagulation | pregnant = LMWH + aspirin throughout
