Contrary to expectation in this 10-year observational study, all-cause, cardiovascular and cancer mortality increased slightly (about 8%) with Allopurinol dose escalation, especially in the first 2 years; albeit the increase was not statistically significant.
But less than a third of the dose-escalators achieved serum uric acid target of <6 mg%. Among these, there was a 7% reduction in cardiovascular mortality compared to case-matched non-escalators.
