Multicenter Study Clinical TrialEstimated glomerular filtration rate reversal by blood pressure lowering in chronic kidney disease: Japan Multicenter Investigation for Cardiovascular DiseaseB CKD study.
Patients are diagnosed as having chronic kidney disease (CKD) if estimated glomerular filtration rate (eGFR) is <60 mL/min/1.73 m(2). Low eGFR is likely to increase the incidence of cardiovascular events and lead to dialysis. Therefore, it is important to prevent eGFR from decreasing eGFR. ⋯ Regardless of the type of antihypertensive drugs used, eGFR was significantly increased in patients with CKD and was significantly decreased in patients without CKD. This paper shows that antihypertensive therapy can improve eGFR in hypertensive patients with CKD. J Clin Hypertens (Greenwich). 2012;00:00-00. ©2012 Wiley Periodicals, Inc.

Randomized Controlled Trial Multicenter StudyCombination angiotensin-receptor blocker (ARB)/calcium channel blocker with HCTZ vs the maximal recommended dose of an ARB with HCTZ in patients with stage 2 hypertension: the exforge as compared to losartan treatment in stage 2 systolic hypertension (EXALT) study.
This study compared the efficacy and safety of combination angiotensin-receptor blocker (ARB)/calcium-channel blocker (CCB) with hydrochlorothiazide (valsartan/amlodipine/HCTZ 160/5/2mg) vs maximal available combination doses of an ARB with HCTZ (losartan/HCTZ 100/25 mg) in the management of stage 2 hypertension. After 1 to 2 weeks of antihypertensive drug washout, patients with a mean sitting systolic blood pressure (MSSBP) of ≥ 160 mm Hg and <200 mm Hg were randomized to valsartan/amlodipine 160/5 mg (n = 241) or losartan 100 mg (n = 247). At week 3, HCTZ 25 mg was added to both treatments. ⋯ Achievement of blood pressure <140/90 mm Hg also favored the valsartan/amlodipine group. Dizziness was the only adverse event reported in >5% of patients (5.4% valsartan/amlodipine group, 3.6% losartan group). Moderate doses of an ARB/CCB combination with HCTZ reduced blood pressure more effectively than the maximal dose of an ARB with HCTZ.

Randomized Controlled Trial Multicenter Study Comparative StudyEffects of calcium channel blockers on proteinuria in patients with diabetic nephropathy.
Diabetic nephropathy management should include the use of an angiotensin-converting enzyme inhibitor (ACEI) or an angiotensin receptor blocker with additional antihypertensive medications to reduce proteinuria and cardiovascular events. Some studies suggest that adding a nondihydropyridine rather than a dihydropyridine calcium channel blocker (CCB) may more effectively lower proteinuria. We hypothesized that a trandolapril/verapamil SR (T/V) fixed-dose combination (FDC) was superior to a benazepril/amlodipine (B/A) FDC for reducing albuminuria in 304 hypertensive diabetic nephropathy patients when treated for 36 weeks. ⋯ There were significant reductions in log UACR (mean change in T/V, -0.28; P<.01; mean change in B/A, -0.31; P<.001) and diastolic blood pressure in both groups and in systolic blood pressure in the B/A group. T/V was not superior to B/A for reducing UACR. Both ACEI/CCB FDCs may reduce albuminuria; in the case of T/V, this appears to be independent of systolic blood pressure reduction in patients who had previously been treated and had baseline blood pressure levels of 142/77 mm Hg.

Multicenter Study Controlled Clinical TrialThe efficacy and safety of low- and high-dose fixed combinations of irbesartan/hydrochlorothiazide in patients with uncontrolled systolic blood pressure on monotherapy: the INCLUSIVE trial.
This multicenter, prospective, open-label, single-arm study determined the efficacy and safety of irbesartan/hydrochlorothiazide (HCTZ) fixed combinations in patients (n=1005), aged 18 years and older, with uncontrolled systolic blood pressure (SBP) of 140-159 mm Hg (130-159 mm Hg for type 2 diabetes mellitus) after at least 4 weeks of antihypertensive monotherapy. Treatment was sequential: placebo (4-5 weeks), HCTZ 12.5 mg (2 weeks), irbesartan/HCTZ 150/12.5 mg (8 weeks), and irbesartan/HCTZ 300/25 mg (8 weeks). Enrolled patients (n=844) were aged 57.3+/-11.2 years; 52% were women, 23% were African American, and 14% were Hispanic. ⋯ Overall, 77% (95% confidence interval, 74%-80%) of patients achieved SBP goal (<140 mm Hg; <130 mm Hg for type 2 diabetes mellitus); 83% (95% confidence interval, 80%-86%) achieved DBP goal (<90 mm Hg; <80 mm Hg for type 2 diabetes mellitus); and 69% (95% confidence interval, 66%-72%) achieved dual SBP/DBP goal. Treatments were well tolerated. This irbesartan/HCTZ treatment regimen achieved SBP goals in more than 75% of patients uncontrolled on monotherapy.

Randomized Controlled Trial Multicenter StudyComparison of a chronotherapeutically administered beta blocker vs. a traditionally administered beta blocker in patients with hypertension.
Increasing systolic blood pressure and heart rate during the early morning results in increased myocardial oxygen demand. The use of beta blockers during this period may decrease cardiac workload, particularly in beta-blocker sensitive patients. The impact of a new chronotherapeutic beta blocker was assessed in 44 hypertensive patients. ⋯ Mean blood pressure reductions in the beta-blocker sensitive patients (n = 11) between 6 a.m. and noon were -15.2/-11.9 mm Hg on INP and -8.0/-4.6 mm Hg on ILA. Heart rate reduction was -14.1 bpm and double product reduction was -3319 in the INP patients between 6 a.m. and 12 noon compared with -10.5 and -2209 in the ILA patients. This study suggests that INP and ILA are effective once-a-day beta blockers, but the use of delayed-release propanolol results in a greater reduction in double product between 6 a.m. and noon in beta-blocker sensitive patients than does traditionally dosed propranolol.
