gout 以 allopurinol 治療,會產生 xanthinuria 因而 renal failure 嗎?

PubMed: gout xanthinuria allopurinol
PubMed: gout* xanthin* allopurinol
有 231 篇,大部分都是介紹新藥 febuxostat
PubMed: iatrogenic Xanthinuria
就算是 allopurinol xanthinuria 也只有 33 篇不是很相關的文獻…
為何腎臟科醫師對 longstanding severe tophaceous gout w CRF (ESR 25-30) 以 allopurinol 治療有這些疑慮呢…
不過風濕科看到的是不治療 tophaceous gout 最後腎臟壞了去洗腎的比規則治療去洗腎的多…可能有個人的 selection bias
但很嚴重的 tophaceous gout 要說服病人讓他願意接受規則治療控制尿酸實在是不容易啊…
我比較怕 SJS 而不擔心 xanthinuria
