“…Other studies give a more precise definition of colchicine resistance, but again the different definitions are highly variable. The highest agreement for colchicine resistance is the persistent elevation of acute phase reactants between the attacks ( 12 , 15 – 20 , 23 , 24 , 26 – 29 , 33 , 34 , 36 , 38 – 40 , 44 , 46 , 49 , 50 , 52 , 55 , 57 – 59 , 61 , 63 – 65 , 73 ). No consensus exists about attack frequency: some authors define colchicine resistance in patients who experience more than 1 typical inflammatory attack per 3 months ( 38 , 53 ), while others refer to colchicine resistance if there are more than 2 typical attacks per trimester ( 46 ) and still others if the patient has monthly attacks ( 35 , 40 , 48 , 51 , 52 , 55 , 59 , 62 – 65 ).…”
