Allopurinol Dose Escalation and Mortality Among Patients With Gout: A National Propensity-Matched Cohort Study.

This is the largest study to date to investigate the effects of allopurinol use on mortality and is the first to use a rigorous active-comparator design. Dose escalation was associated with a small (<10%) increase in all-cause mortality, thus showing that a strategy of allopurinol dose escalation, which in current real-life practice is characterized by limited dose increases, is unlikely to improve the survival of patients with gout.
