low c3 and c4
high crp and esr
urine protein:creatinine ratio to find renal fucntion and renal biopsy to see if lupus neprhtitis
high immunoglobulins
whats the complications of sle
cv disease - v high cause death =. inflam of bv causes hypertension and coronary artery disease

telangiectasia
whats the features of diffuse cutaneous systemic sclerosis
CREST
and affects interna; organs:
cv= ht and coronary artery disease
lungs= pulmonary ht and pulmonary fibrosis
kinde= glomerulonepthritis and scleroderma renal crisis= acute server ht and renal failure
whats scleroderma
hardening of skin
shiny and tight without normal folds
hands and face esp
whats scelrodactyl
skin tightens around joints so decrease range of movement and fucntion
skin cxan break and ulcerate
whats telangiectasia
dilated small bv in skin
on x ray what see on hands of pateint with systemic sclerosis
white dots= calcinoisis
what happens in oesophageal dysmotility in systemic scleoriss
connective tissues dysdunction in oesopahgus
swallowing difficulties
acid reflux
oesophagitis
patient has gradual onset of dry cough and sob and got raynauds and hardening of skin on hands
what is this

Antinuclear antibodies= ANA = not specific to systemic sclerosiis
what antibodies suggest pt has limited cutaneous systemic scleorisis
anti-centromere antibodies
what antibodies suggest diffuse cutaneous systemic sclerosis
anti-Scl-70 antibodies
how do you distinguish between pt with raynauds and if they have got systemic sclerosis
nailfold capillaroscopy
if its abnormal
avascualr areas
micro haemoorages then indicates systemic scleorsis
how to diagnose systemic sclerosis
nailfold capillaroscopy
features
antibodies

whats inital management for giant cell arteritis
steroids imediately before confirming diagnosis
40-60mg prednisolone once daily
review in 48 hrs - should get response to treamtent
aspirin 75mg od to decrease vision loss and stroke
ppi to protect against steroids
referal to vascualr durgeon for temporal artery biopsy
to rheumatology
to ophthalmology same day if get vision symtooms
when do you give 60mg prednisolone to pt wth suspected fiant cell arteritis
if got jaw claudication or vision symtpoms give the higher dose of prednisolone
whats do you do for ongoing managemnt for giant cell arteirtis if diangosis been confirmend
continute steorids until sysmtos resolved then weak off slowly
dont stop= dont stop steroids abruptly as risk adrenal crisis

clinical presentation
temporal artery biopsy finsings
these three give diangosis of it
may also do
fbc= see normocytic anaemia/ thrombocytosis= raised platelets
rasied CRP

what will you see on biopsy of temporal artery in giant cell arteritis
multinucleated giant cells
hypoechoic halo sign on temporal artery us suggest what
giant cell arteritis

management for OA
physio
occupational therpay
psycho
weight loss
orthotics
step wise analgeisa:
oral paracetamol, topical nsaids/ topical capsaicin= dec substance p
2= add oral nsaids and ppi

pain
swelling
multiple joints
often symmetircal
hands, feet, ankles, wrist, MCP, PIP in hands
onset can be rapid/months years
dip in hands vvvv rarely affected in RA so if are probs oa
systemic symtoms =
fatigue
weight loss
flu like
muscle aches, weakenss
whats palindromic RA
short episodes of inflammatroy arthritis with pian and stiff and swelling but 1-2 days then resolves
if got rf and anti ccp may progress to full RA
whats atlantoaxial subluxation
cervical spine
axis and peg shift with atlas due to synovitis damage to ligaments and bursa
need take care with gerneal anesthetic and intubatio n

if rf negative check for anti CCP antibodies
inflammatory markers- crp, esr
x ray of hands and feet
ultra sound of joints to see if synotivitis
whtas diangositc criteria for RA
Referral
NICE recommend referral for any adult with persistent synovitis, even if they have negative rheumatoid factor, anti-CCP antibodies and inflammatory markers. The referral should be urgent if it involves the small joints of the hands or feet, multiple joints or symptoms have been present for more than 3 months.
Diagnosis
Diagnostic criteria come from the American College of Rheumatology (ACR) / European League Against Rheumatism (ELAR) from 2010:
Patients are scored based on:
The joints that are involved (more and smaller joints score higher)
Serology (rheumatoid factor and anti-CCP)
Inflammatory markers (ESR and CRP)
Duration of symptoms (more or less than 6 weeks)
Scores are added up and a score greater than or equal to 6 indicates a diagnosis of rheumatoid arthritis.
DAS28 Score
The DAS28 is the Disease Activity Score. It is based on the assessment for 28 joints and points are given for:
Swollen joints
Tender joints
ESR/CRP result
It is useful in monitoring disease activity and response to treatment.
