what is RA?
chronic inflammatory progressive disease caused by production of autoantibodies which attack the cells lining small joints
symptoms of RA
- pain
- swelling
- joint deformity
- joint swelling
- stiffness
when are symptoms of RA worse?
in morning or after a period of inactivity
what are flare ups?
period of time where symptoms of RA are worse
how can RA be detected from blood samples?
- inc WBC (bc inflammatory)
- inc ESR (AB’s can bind to RBC hence drop to bottom, sediment, of tube faster)
- anaemia
- rheumatoid factor (AB’s for IgG)
risk factors for RA
Age --> peak age now 65-75 years Gender --> premenopausal f>m, post m=f Post-partum Stress Genetic Smoking
how does movement affect RA?
- improves on movement but worse in morning
first line treatment for RA according to NICE is …
DMARD + glucocorticoid
why is a glucocorticoid used alongside a DMARD?
as bridging therapy.
- used short term to improve symptoms whilst waiting for DMARD to kick in
what DMARDS can be considered for initial treatment of RA?
mtx, sulfasalazine, leflunomide (with dose escalated as needed)
- hydroxychloroquine if mild or palindromic RA
Indication and dose of prednisolone for RA
- Indication – reduction in rate of joint destruction in moderate to severe RA of less than 2 years’ duration.
- 30-40mg daily (usually 6-8 tablets all to be taken at once)
side effects of prednisolone
- gastro-effects
- can affect breathing and cause bronchospasm
- anxiety
- abnormal behvaiour
- fatigue
how to combat gastro effects of prednisolone in RA bridging therapy
PPI is recommended for use when on steroid due to gastro effects BUT as soon as steroid finished, PPI should be stopped
use of NSAIDS and prednisolone
AVOID
- any NSAIDS, aspirin, anticoagulants and SSRI’s to be avoided with prednisolone
when should a PPI be provided with a steroid?
when having repeating courses of the steroid
treatment cessation for prednisolone
- if pt having for less than 3 weeks then can be abruptly stopped
- but peter seems to be relapsing patient and has had 40mg daily for more than 1 week hence needs to be ADJUSTED AND TITRATED OFF
why is it necessary to wean off prednisolone?
to allow bodies renal system and adrenal glands to return to normal function as have suppressed the adrenocortical response
Abrupt withdrawal = hypotension, acute adrenal insufficiency
cautions of prednisolone
- avoid if have pre-existing CVS issues as get water retention issues to heart
- avoid live virus vaccines
- CHF, diabetes, epilepsy
counselling points for prednisolone
- single dose with food AM
- avoid contact with those with chickenpox, shingles, infections etc
- dont abruptly stop medication
- carry steroid card around
comorbidities with RA
- hypertension
- MI
- stroke
- lung damage (hence peter smoking increases risk further)
where does RA usually affect?
small joints of hands and feet usually bilaterally
mtx indication and dose
indication: moderate to severe RA
DOSE: 7.5mg, max 20mg ONCE A WEEK by mouth after food (will be gradually increased)
cautions of mtx
- diarrhoea –> signs of GI toxicity hence tretament must be stopped
- liver issues –> discontinue if an issue and abnormalities should return to normal in 2 weeks, start over again
- pulmonary toxicity (for those w RA) –> seek medical attention if dyspnoea, cough or fever
what should be immediately reported when on mtx?
- blood disorder features (sore throat, bruising, mouth ulcers)
- liver toxicity (n+v, dark urine, ab discomfort)
- respiratory effects (SOB)
