Gout - Ix + Mx Flashcards
Investigation;
Bloods: ???, ??? & serum ? ?.
o ? does not confirm gout, and a ? uric acid level
during an ? attack does not exclude gout, as levels ? as part of the ? ? reaction

o In acute gout, ? fluid shows increased ? due to the elevated cell count.
o Urate crystals will be ? ? and ? shaped in
polarised light microscopy.

XR can assess the ? of joint damage; usually ? in early disease, but with long-standing disease the changes of ?? may develop
Gouty ‘erosions’ (? ?) are a less common but more specific feature,
appearing as periarticular ‘? ?’ defects.
In the longer-term, it may be prudent to search for an underlying cause, with

Management
The Acute Episode of Gout;

o Oral ? is used instead of NSAIDs in ? patients, patients

Early ? of the joint combined with ? injection can
effectively abort the acute attack.

The aim of treatment is to bring serum uric acid level into the ? ? of
the ? range.
The serum uric acid level should be measured every ?, and the dose
? in ?mg increments to a maximum of ?mg daily until uric acids are within this range (then ? monitoring).

Treatment is only initiated after an acute attack has ?, usually after ?
weeks, so as not to ?/prolong the attack;
o The ? in tissue uric acid levels after initiation can partially ? MSUM crystals and trigger ? attacks.
o Concurrent ? given for a ?period for this reason.

Lifestyle advice to reduce ?, total ?/? intake, and avoid
certain food groups (including offal, ? and spinach) is also important.
Other pharmacological options are ? drugs, e.g. ? or
sulfinpyrazone, which lead to increased ? of uric acid in the ?.
o Contraindicated in ? impairment, patients with a history of ?, or over-? of uric acid (excretion already high).
