NCT01532622

Brief Summary

The purpose of this study is to determine the impact of blueberries on uric acid in patients with hyperuricemia that are not receiving uric acid pharmacotherapy. The central hypothesis the investigators propose is that daily blueberries added to a pre-existing diet will promote uric acid lowering and improve quality of life without detriment to vital signs.

Outcome Measures

Primary Outcomes (1)

  • Change from Baseline and Placebo in Uric Acid Level in Patients Randomized to Treatment Group

    Percent change in uric acid level from baseline after 30 days of treatment with blueberry powder. Since this is designed as a crossover trial, baseline could represent uric acid level at the beginning of the study or after at least a 2-week washout period following placebo administration.

    Baseline, ~30 days later

Secondary Outcomes (3)

  • Blood Pressure

    Baseline, ~30 days, ~45 days, ~75 days

  • Body Weight

    Baseline, ~30 days, ~45 days, ~75 days

  • Quality of Life

    Baseline, ~30 days, ~45 days, ~75 days
