Lyn,
I've seen none in myself. I can eat aspirin like candy although other NSAIDS give me problems like gastritis from ibuprofen and dizzinelss from Indocin.
My reasearch has shown that aspirin has markedly divergent properties: in small doses it retains uric acid; in HUGE doses it expels it.
But, if you're implying that aspirin helps gout and that those who cannot take aspirin are thus more at risk, I think there's no linkage there. Aspirin in normal doses is not a drug to be taken for acute gout, nor as a preventative and there are few people who can take the 4+ grams/day necessary for its uricosuric action (like 16 aspirin.)
