Analysis of Gout Remission Definitions in a Randomized Controlled Trial of Colchicine Prophylaxis for People With Gout Initiating Allopurinol.
Objective: To investigate (1) the effect of colchicine prophylaxis on gout remission when commencing urate-lowering therapy (ULT), and (2) illness perceptions of people in remission using 2 definitions of gout remission.
Methods: Data from a 12-month double-blind placebo-controlled trial of 200 people with gout commencing allopurinol were analyzed. Participants were randomly assigned to prophylaxis with 0.5 mg daily colchicine or placebo for 6 months, followed by 6 months of additional follow-up. Gout remission was assessed using the 2016 preliminary definition or simplified definition without patient-reported outcomes. Illness perceptions were assessed using a gout-specific version of the Brief Illness Perception Questionnaire.
Results: In the first 6 months, few participants were in remission according to either the 2016 preliminary definition (3% for colchicine and 4% for placebo) or the simplified definition (7% for colchicine and 12% for placebo). In the second 6 months, after study drug (colchicine or placebo) discontinuation, fewer participants in the colchicine group than in the placebo group were in remission according to the 2016 preliminary definition (4% vs 14%, P = 0.03), and the simplified definition (14% vs 28%, P = 0.02). Participants fulfilling remission using either definition had more favorable perceptions about their gout symptoms and illness concerns, as well as consequences, when using the simplified definition.
Conclusion: Using either definition, 6 months of colchicine prophylaxis when initiating ULT does not provide an advantage in the fulfillment of gout remission. People fulfilling either definition report fewer symptoms, less concern about their gout, and, when using the simplified definition, are less affected by gout.
