Gout Flashcards
what is gout
crystal induced joint disease
what are the crystal deposits formed from
uric acid
what types are there
primary and secondary
which is most common in men
primary
primary are usually caused from
metabolic problem
secondary are usually caused from
cell destruction (leukemia)
renal problem
alcohol
chem
Primary Patho
altered purine metabolism - asymptomatic hyperuricemia
what is purine metabolism
break down of the bases adenine and guanine
what is hyperuricemia
increase uric acid in the blood
what happens to this uric acid later on
uric acid forms crystals in the synovial fluid and deposits in the synovial joints
these crystal deposits trigger…
WBC influx and complement activation (leukocytes die when they phagocytize the crystals) - they release an enzyme - this enzyme targets the joints causing inflammation and damage
what occurs with recurrent attacks
tophus
what is tophus
crystalline uric acid at surface of joints or in the skin of cartilage
how many stages are there of gout
5
what are these stages
- asymptomatic hyperuricemia
- acute inflammation (usually at the toe joint)
- subsides in ~ 1 week
- asymptomatic for months to years
- frequent recurrent attacks = permanent damage to joints
