Blood pressure control among patients with hypertension and newly diagnosed diabetes.

ABSTRACT: To determine the proportion of patients who achieved blood pressure control during the 2 years following new diabetes diagnosis.A retrospective cohort of veterans ? 18 years with hypertension who initiated a diabetes medication from 2000 to 2007 in the Veterans Administration Mid-South Network was assembled. Blood pressure control at diabetes treatment initiation (baseline) was compared with blood pressure control 6, 12, 18 and 24 months later. The Veterans Affairs and American Diabetes Association definitions of control, ? 140/90 and ? 130/80 mmHg, respectively, were primary and secondary outcomes.At baseline, 59.5% of 16,182 patients had controlled blood pressure according to the Veterans Affairs guideline (31.5% using American Diabetes Association definition). Six months following initiation of diabetes treatment, 65.7% had their blood pressure controlled (P < 0.001). Blood pressure control was sustained but not further improved between 6 months and 2 years, with 66.5% controlled at 2 years following baseline. Higher initial systolic blood pressure, black race and hospitalization in the previous year were associated with higher likelihood of uncontrolled blood pressure at 6 months; whereas baseline cardiovascular disease, baseline dementia and later year of cohort entry were associated with lower likelihood of uncontrolled blood pressure.We found an increase in blood pressure control in the 6 months following initiation of diabetes treatment. However, overall blood pressure control remained suboptimal and with no further improvement over the next 18 months.

Project description:ContextHyperuricemia is a predictor for the development of hypertension and is commonly present in new-onset essential hypertension. Experimentally increasing uric acid levels using a uricase inhibitor causes systemic hypertension in animal models.ObjectiveTo determine whether lowering uric acid lowers blood pressure (BP) in hyperuricemic adolescents with newly diagnosed hypertension.Design, setting, and patientsRandomized, double-blind, placebo-controlled, crossover trial (September 2004-March 2007) involving 30 adolescents (aged 11-17 years) who had newly diagnosed, never-treated stage 1 essential hypertension and serum uric acid levels > or = 6 mg/dL. Participants were treated at the Pediatric Hypertension Clinic at Texas Children's Hospital in Houston. Patients were excluded if they had stage 2 hypertension or known renal, cardiovascular, gastrointestinal tract, hepatic, or endocrine disease.InterventionAllopurinol, 200 mg twice daily for 4 weeks, and placebo, twice daily for 4 weeks, with a 2-week washout period between treatments. The order of the treatments was randomized.Main outcome measuresChange in casual and ambulatory blood pressure.ResultsFor casual BP, the mean change in systolic BP for allopurinol was -6.9 mm Hg (95% confidence interval [CI], -4.5 to -9.3 mm Hg) vs -2.0 mm Hg (95% CI, 0.3 to -4.3 mm Hg; P = .009) for placebo, and the mean change in diastolic BP for allopurinol was -5.1 mm Hg (95% CI, -2.5 to -7.8 mm Hg) vs -2.4 (95% CI, 0.2 to -4.1; P = .05) for placebo. Mean change in mean 24-hour ambulatory systolic BP for allopurinol was -6.3 mm Hg (95% CI, -3.8 to -8.9 mm Hg) vs 0.8 mm Hg (95% CI, 3.4 to -2.9 mm Hg; P = .001) for placebo and mean 24-hour ambulatory diastolic BP for allopurinol was -4.6 mm Hg (-2.4 to -6.8 mm Hg) vs -0.3 mm Hg (95% CI, 2.3 to -2.1 mm Hg; P = .004) for placebo. Twenty of the 30 participants achieved normal BP by casual and ambulatory criteria while taking allopurinol vs 1 participant while taking placebo (P < .001).ConclusionsIn this short-term, crossover study of adolescents with newly diagnosed hypertension, treatment with allopurinol resulted in reduction of BP. The results represent a new potential therapeutic approach, although not a fully developed therapeutic strategy due to potential adverse effects. These preliminary findings require confirmation in larger clinical trials.Trial registrationclinicaltrials.gov Identifier: NCT00288184.
