“…In addition, we have seen different results on the impact of gout flare treatment on renal function in case reports and case series. For instance, 12 studies reported deteriorated renal function with colchicine use [17,20,22,24,32,33,35,39,44,53,55,57], whereas 7 other studies reported stable renal function with colchicine use [18,28,29,31,36,46,53]. As a result, given the underlying risk of bias on study quality for these studies, we cannot sufficiently conclude on the efficacy and/or safety outcomes on colchicine use for people with gout and concomitant CKD.…”
