title: Diet and medication in the treatment of hyperuricemia in hypertensive patients.
abstract: OBJECTIVE
  To evaluate the effects of diet and medication, either isolated or associated, on serum levels of uric acid in patients with hyperuricemia.
  
  
  METHODS
  We studied patients from the Hypertension Unit of the University of Goias who had hyperuricemia (men > or =8.5 mg/dL and women > or =7.5 mg/dL). We divided the patients into three groups: G1 (low purine diet), G2 (low purine diet + medication), and G3 (medication only). Patients received allopurinol, 150 mg/day titrated up to 300 mg/dL when necessary. Patients were evaluated with regards to their lifestyles (diet, smoking, physical, activity, alcohol consumption), uric acid, blood pressure, use of medication, body mass index, cholesterol, and triglyceride. Follow-up took place in weeks 0 (M1), 6 (M2), 12 (M3) during the intervention and in week 36 (M4) after the study was completed.
  
  
  RESULTS
  Fifty-five patients participated in the study, 31 women, mean age 54.4+/-10.6 years, body mass index 28.6+/-3.9 kg/m2. A similar reduction (p<0.001) in uric acid levels occurred in the three intervention groups. In week 36 (M4), after 24 weeks without intervention, a tendency toward elevation of uricemia was noted in G2 and G3, and a continuous drop in uricemia was noted in G1. No significant modifications were observed in the other variables analyzed.
  
  
  CONCLUSIONS
  Considering the cost x benefit relationship, a diet low in purine should be the 1st therapeutic option for controlling hyperuricemia in patients with similar characteristic to the ones presented in this study.
