Study Description
Brief Summary:
The purpose of this study is to evaluate the influence of hyperuricemia treatment compared with placebo on participants with high risk of hypertension and metabolic syndrome.

Condition or disease Intervention/treatment Phase
Systolic and Diastolic Blood Pressure Levels Uric Acid Levels Metabolic Syndrome Parameters Hepatic Enzymes Drug: Allopurinol Other: placebo Phase 2

Detailed Description:

Elevated consumption of high fructose corn syrup has lead to an increase of 30% of fructose intake since the last 20 years. Important data supporting this fact can be reflected on incidence and prevalence of Metabolic syndrome and hyperuricemia.

A peculiar effect of fructose intake demonstrated in animal models is the development of elevated uric acid levels; also some studies have found a clear association between hyperuricemia as an important risk factor for hypertension, diabetes mellitus, chronic kidney disease and metabolic syndrome.

Taking into account the existing evidence, our clinical research team presents this protocol as a way to evaluate the effect of uric acid treatment and its relation with Fructose consumption, metabolic syndrome parameters, hyperuricemia and risk of hypertension.

Confirming evidence with clinical basis may be the initial strategy to create primary prevention programs to control this health problems affecting Mexican Population.

Outcome Measures

Primary Outcome Measures :
  1. Effect of hyperuricemia treatment on systemic blood pressure [ Time Frame: 14 weeks ]
    participants will be randomized to a 4 week placebo versus alopurinol treatment followed by a wash out period. After crossover them, they will receive the complementary pharmacological intervention for another 4 weeks.

Secondary Outcome Measures :
  1. Effect of hyperuricemia treatment on metabolic syndrome parameters [ Time Frame: 14 weeks ]
    baseline and final laboratory samples during pre and post crossover periods will include metabolic syndrome measurements (triglycerides, cholesterol, glucose and abdominal perimeter).
