Therapeutics 2 Flashcards
aetiology of autoimmunity
- ?
○ Failure of the ? to get rid of ?? that have a high affinity for ?? - autoimmune conditions have a defect in the ? and ? of ??? which has a ? basis - ? ‘trigger’
Trigger signals ?? to activate ??? which triggers an immune response and causes ??. Trigger is often a ? that mimics a ?.
genetic
thymus
T cells
self antigens
number
function
regulatory T cells
genetic
environmental
dentritic cells
t helper cells
tissue damage
pathogen
self-antigen
what drugs are used to manage autoimmune diseases? 4
analgesics/NSAIDs
corticosteroid
DMARDs
biologics
If a pt is taking corticosteroid and NSAID will also be prescribed what? why?
proton pump inhibitor
to prevent GI problems
corticosteroid is used to treat autoimmune diseases
? the immune system - reduces ?? and ? by binding to ? which blocks ??
suppresses
autoimmune response
inflammation
glucocorticoid
cytokine transcription
how is corticosteroid given to pt with autoimmune diseases? 2
Can have hydrocortisone/triamcinolone intra-articular injection
Can have oral prednisolone
when is oral prednisolone used to treat autoimmune disease?
Used during acute flares or at the start of diagnosis when disease is uncontrolled
Start high then taper of
why is it important to review tapering off of oral prednisolone?
in case of relapse
why is it important to reduce the dose of oral prednisolone slowly?
to prevent acute adrenal deficiency leading to severe low blood pressure
side effects of corticosteroid 6
Hypertension
impaired diabetic control
hyperglycaemia (high glucose)
osteoporosis
increased weight
GI affects (peptic ulcers and Cushing syndrome)
what is important to prescribe for long term use of corticosteroid, why?
○ Proton pump inhibitor important for long term use to prevent GI problems (peptic ulcers)
dental affects of corticosteroids 4
Increased susceptibility to infection
Candidosis
MRONJ
Steroid prophylaxis on days of procedure when traumatic
what do DMARDs do? 2
Suppress the immune system and prevent progression
compare biologics to DMARDS
biologics are proteins that target specific sites so no systemic involvement like traditional DMARDs
