The Effect of Tart Cherry Juice on Risk of Gout Attacks

The Effect of Tart Cherry Juice on Risk of Gout Attacks: a Randomised Controlled Trial

Difference in gout flare frequency in tart cherry juice group versus placebo group from baseline to 12 months. Recorded as number per month.

Difference in gout flare intensity in tart cherry juice group versus placebo group from baseline to 12 months. Using a 0-10 Likert pain scale. The scale measures the pain of any gout flare. The possible score ranges from 0 for no pain through to 10 for worst pain imaginable. Change in pain scores between treatment and placebo groups will be compared throughout the duration of the intervention.

Difference in serum urate in tart cherry juice group versus placebo group from baseline to 12 months.

Difference in fractional excretion of uric acid in tart cherry juice group versus placebo group from baseline to 12 months. Measured from 24 hour urine sample.

Difference in inflammatory markers (c reactive protein (CRP), inter leukin-6 (IL-6) and tumour necrosis factor- alpha (TNF-alpha)) in tart cherry juice group versus placebo group from baseline to 12 months. Measured using an enzyme-linked immunosorbent assay (ELISA).

Difference in markers of oxidative stress in tart cherry juice group versus placebo group from baseline to 12 months. Measured using single-cell electrophoresis 'comet assay' as 8-oxo-dg levels in lymphocytes.

Difference in antioxidant status in tart cherry juice group versus placebo group from baseline to 12 months. Measured using single-cell electrophoresis 'comet assay' as resistance of DNA lymphocyte to H202-induced DNA strand breaks.

Difference in brachial and central blood pressure in tart cherry juice group versus placebo group from baseline to 12 months. Measured using a Vicorder.

Difference in arterial stiffness in tart cherry juice group versus placebo group from baseline to 12 months.

Difference in total cholesterol, HDL cholesterol, LDL cholesterol and triacylglycerides) in tart cherry juice group versus placebo group from baseline to 12 months.

Height and weight will be combined to report BMI in kg/m^2. Difference in BMI in tart cherry juice group versus placebo group from baseline to 12 months.

4 day diet diaries will be used to assess any changes in habitual diet as a result of, or over the course of, the study.

4 day physical activity logs will be used to assess any changes in habitual activity levels as a result of, or over the course of, the study.
