Abstract
PURPOSE The present study aims to assess and compare the effects of carvedilol and terazosin plus enalapril on lower urinary tract symptoms (LUTS), the urine flow, and blood pressure (BP) in patients with moderate hypertension (HTN) and benign prostatic hyperplasia (BPH). MATERIALS AND METHODS In this randomized crossover trial, a total of 40 men with HTN and LUTS symptoms were enrolled. The first group was treated with carvedilol, and the second one received terazosin plus enalapril. After eight weeks of treatment, the patients experienced a one-month washout period, and the treatments changed and continued for eight weeks. To diagnose BPH in the study, the international prostate symptom score (IPSS) questionnaire was used. Moreover, the prostate-specific antigen (PSA), the post-void residual (PVR) urine volume, and the maximum urinary flow rate (Q-max using the uroflowmetry test) were measured. RESULTS Effect assessment results in this crossover trial illustrated neither carryover effects nor significant treatment effects on all primary outcomes (P > 0.05). Moreover, the results for the period effect indicated a significant reduction in BP (systolic and diastolic), PVR, and IPSS, yet a significant raise in Qmax. CONCLUSION The effects of carvedilol are similar to those of the combination of terazosin and enalapril in patients with moderate HTN and BPH in controlling LUTS. Carvedilol could be used as an appropriative drug in patients with moderate HTN and cardiac problems with LUTS of BPH. Further studies are recommended to be conducted to investigate and compare the efficacy of carvedilol with that of other alpha-blockers with a larger sample size and over a longer period of time.

Abstract
INTRODUCTION The present study evaluated the quality of medical care for patients diagnosed with diabetes mellitus (DM), hypertension (HBP), and both pathologies (DM+HBP) within a public health system in Mexico. METHODS 45,498 patients were included from 2012 to 2015. All information was taken from the electronic medical record database. Each patient record was compared against the standard to test the quality of medical care. RESULTS Glycemia with hypertension goals reached 29.6% in DM+HBP, 48.6% in DM, and 53.2% in HBP. The goals of serum lipids were reached by 3% in DM+HBP, 5% in DM, and 0.2% in HBP. Glycemia, hypertension, and LDL cholesterol reached 0.04%. 15% of patients had an undiagnosed disease. Clinical follow-up examinations reached 20% for foot examination and clinical eye examination. Specialty referrals reached 1% in angiology or cardiology. CONCLUSION Goals for glycemic and hypertension reached 50% in the overall population, while serum lipids, clinical follow-up examinations, and referral to a specialist were deficient. Patients who had both diseases had more consultations, better control for hypertension and lipids, but inferior glycemic control. Overall, quality care for DM and/or HBP has not been met according to the standards.

Abstract
INTRODUCTION Albuminuria is an early marker of kidney disease and reduction of albuminuria translates into a decreased occurrence of cardiovascular and renal outcomes. AIMS To evaluate the changes in the prevalence of albuminuria in diabetic hypertensive patients treated with several combinations of renin-angiotensin aldosterone system with calcium channel blockers. METHODS We analysed data from 668 unselected patients from the PAIT survey (mean age 60.4 ± 10.2 years, prevalence of males 38%), with and without albuminuria, maintained for 6 months with the previous treatment with amlodipine-valsartan, amlodipine perindopril, lercanidipine-enalapril, verapamil-trandolapril, nitrendipine-enalapril and felodipine-ramipril Albuminuria was assessed, as urinary albumin-creatinine ratio, using a Multistic-Clinitek device analyzer. Microalbuminuria was defined as a loss of 3.4-33.9 mg albumin/mmol creatinine (30-300 mg/g) and macroalbuminuria as a loss of > 33.9 mg albumin/mmol creatinine (> 300 mg/g). Blood pressure was measured with a validated digital device. RESULTS At baseline, albuminuria was present in 310 subjects (46.4%) (microalbuminuria in 263 (84.8%), macroalbuminuria in 15.2%), and normoalbuminuria in 53.6% 358. After 6 months, the prevalence of subjects with albuminuria was significantly lowered (p < 0.01) by 23.5% (microalbuminuria - 23.9%, p < 0.01 and macroalbuminuria - 21.3%). The prevalence of subjects with microalbuminuria was reduced with all treatments: amlodipine-valsartan - 15.6%, amlodipine-perindopril - 11.8%, lercanidipine-enalapril - 41.3% and verapamil-trandolapril - 19.2%. Data with nitrendipine-enalapril and felodipine-ramipril were not analyzed, due to the low number of patients. The frequency of patients with normoalbuminuria was significantly higher (p < 0.01) with lercanidipine-enalapril compared with any other treatment. Blood pressure was significantly (p < 0.01) reduced, with a similar effect between treatments. CONCLUSIONS The treatments decrease the prevalence of subjects with albuminuria, showing a significant difference among the different drug combinations, favoring the use of new dihydropyridine calcium channel blockers, such as lercanidipine, combined with RAAS inhibitors, to control albuminuria in diabetic hypertensive patients.

Abstract
BACKGROUND We conducted a systematic review and meta-analysis to compare benefits and harms of different antihypertensive drug classes in kidney transplant recipients, as post-transplant hypertension (HTN) associates with increased cardiovascular (CV) morbidity and mortality. METHODS The Ovid-MEDLINE, PubMed and CENTRAL databases were searched for randomized controlled trials (RCTs) comparing all main antihypertensive agents versus placebo/no treatment, routine treatment. RESULTS The search identified 71 RCTs. Calcium channel blockers (CCBs) (26 trials) reduced the risk for graft loss {risk ratio [RR] 0.58 [95% confidence interval (CI) 0.38-0.89]}, increased glomerular filtration rate (GFR) [mean difference (MD) 3.08 mL/min (95% CI 0.38-5.78)] and reduced blood pressure (BP). Angiotensin-converting enzyme inhibitors (ACEIs) (13 trials) reduced the risk for graft loss [RR 0.62 (95% CI 0.40-0.96)] but decreased renal function and increased the risk for hyperkalaemia. Angiotensin receptor blockers (ARBs) (10 trials) did not modify the risk of death, graft loss and non-fatal CV events and increased the risk for hyperkalaemia. When pooling ACEI and ARB data, the risk for graft failure was lower in renin-angiotensin system (RAS) blockade as compared with control treatments. In direct comparison with ACEIs or ARBs (11 trials), CCBs increased GFR [MD 11.07 mL/min (95% CI 6.04-16.09)] and reduced potassium levels but were not more effective in reducing BP. There are few available data on mortality, graft loss and rejection. Very few studies performed comparisons with other active drugs. CONCLUSIONS CCBs could be the preferred first-step antihypertensive agents in kidney transplant patients, as they improve graft function and reduce graft loss. No definite patient or graft survival benefits were associated with RAS inhibitor use over conventional treatment.

JAMA network open. 2020;(2):e1921618
Abstract
IMPORTANCE Antihypertension medications have been associated with prevention of cardiovascular events, although less is known about the comparative effectiveness of different medication classes. OBJECTIVE To compare contemporary aggregated first-in-trial cardiovascular events among patients with hypertension and no substantial comorbidities. DATA SOURCES The PubMed, Embase, and Cochrane Library databases were systematically searched for articles published between January 1, 1990, and October 24, 2017. STUDY SELECTION Randomized clinical trials that tested commonly used antihypertension medications (angiotensin-converting enzyme inhibitors, dihydropyridine calcium channel blockers, nondihydropyridine calcium channel blockers, β-blockers, angiotensin receptor blockers, and diuretics) and that reported selected cardiovascular outcomes for at least 6 months of follow-up. DATA EXTRACTION AND SYNTHESIS The analysis was conducted from October 2017 to December 2019. Two reviewers extracted the number of cardiovascular events at the end of treatment for all study groups. For each outcome, a frequentist network meta-analysis was used to compare risk reductions between medication classes (random-effects models weighted by the inverse variance). The dose-response association between a 10-mm Hg reduction of systolic blood pressure and a 5-mm Hg reduction of diastolic blood pressure and the risk of first-in-trial cardiovascular events was estimated. MAIN OUTCOMES AND MEASURES First-in-trial cardiovascular events, including cardiovascular death, myocardial infarction, stroke, and revascularization. RESULTS In this systematic review and network meta-analysis, data were pooled from 46 eligible clinical trials (248 887 total participants with a mean [SD] age of 65.6 [5.8] years; 52.8% men). In the network meta-analysis, compared with placebo, angiotensin-converting enzyme inhibitors, dihydropyridine calcium channel blockers, and thiazide diuretics were reported to be similarly effective in reducing overall cardiovascular events (25%), cardiovascular death (20%), and stroke (35%); angiotensin-converting enzyme inhibitors were reported to be the most effective in reducing the risk of myocardial infarction (28%); and diuretics were reported to be the most effective in reducing revascularization (33%). In the metaregression analyses, each 10-mm Hg reduction in systolic blood pressure and 5-mm Hg reduction in diastolic blood pressure was significantly associated with a lower risk of cardiovascular death, stroke, and overall cardiovascular events. CONCLUSIONS AND RELEVANCE In this network meta-analysis of clinical trials of patients with hypertension and no substantial comorbidities, different classes of antihypertension medications were associated with similar benefits in reducing cardiovascular events. Future studies should compare the effectiveness of combinations of antihypertension medications in reducing cardiovascular events.

American journal of hypertension. 2020;(8):748-755
Abstract
BACKGROUND Antihypertensive therapy using renin-angiotensin system blockers and calcium channel blockers to target blood pressure variability (BPV) has not yet been established. We aimed to compare the ability of losartan and amlodipine to lower BPV and systolic blood pressure (SBP) in essential hypertensive patients. METHODS Patients were randomly assigned either losartan 50 mg or amlodipine 5 mg. Medications were uptitrated and hydrochlorothiazide was added according to protocol for 6 months. The primary endpoint was the office visit-to-visit SD of SBP. The secondary endpoints included average real variability (ARV), office SBP, and home SBP. RESULTS The losartan group (n = 71) and amlodipine group (n = 73) finished the scheduled visits between April 2013 and May 2017. The office visit-to-visit SD of SBP was comparable between the losartan and amlodipine groups (11.0 ± 4.2 vs. 10.5 ± 3.8, P = 0.468). The office visit-to-visit ARV of SBP was significantly elevated in the losartan group (10.6 ± 4.3 vs. 9.1 ± 3.4, P = 0.02). The absolute SBP decrement from baseline to 6 months was similar between groups, although the office mean SBP at 6 months was higher in the losartan group (132.3 ± 12.9 vs. 127.5 ± 9.0 mm Hg, P = 0.011). In home blood pressure analysis, evening day-to-day BPV indexes (SD and ARV) were significantly higher in the losartan group at 6 months. CONCLUSIONS The lowering effect of the office visit-to-visit SD of SBP was similar between losartan and amlodipine. However, the losartan group showed a higher office visit-to-visit ARV of SBP and evening day-to-day home BPV indexes. Therefore, amlodipine may be better to lower BPV in essential hypertensive patients.

Abstract
BACKGROUND Persons with low socioeconomic status and nonwhite persons in the United States have high rates of cardiovascular disease. The use of combination pills (also called "polypills") containing low doses of medications with proven benefits for the prevention of cardiovascular disease may be beneficial in such persons. However, few data are available regarding the use of polypill therapy in underserved communities in the United States, in which adherence to guideline-based care is generally low. METHODS We conducted a randomized, controlled trial involving adults without cardiovascular disease. Participants were assigned to the polypill group or the usual-care group at a federally qualified community health center in Alabama. Components of the polypill were atorvastatin (at a dose of 10 mg), amlodipine (2.5 mg), losartan (25 mg), and hydrochlorothiazide (12.5 mg). The two primary outcomes were the changes from baseline in systolic blood pressure and low-density lipoprotein (LDL) cholesterol level at 12 months. RESULTS The trial enrolled 303 adults, of whom 96% were black. Three quarters of the participants had an annual income below $15,000. The mean estimated 10-year cardiovascular risk was 12.7%, the baseline blood pressure was 140/83 mm Hg, and the baseline LDL cholesterol level was 113 mg per deciliter. The monthly cost of the polypill was $26. At 12 months, adherence to the polypill regimen, as assessed on the basis of pill counts, was 86%. The mean systolic blood pressure decreased by 9 mm Hg in the polypill group, as compared with 2 mm Hg in the usual-care group (difference, -7 mm Hg; 95% confidence interval [CI], -12 to -2; P = 0.003). The mean LDL cholesterol level decreased by 15 mg per deciliter in the polypill group, as compared with 4 mg per deciliter in the usual-care group (difference, -11 mg per deciliter; 95% CI, -18 to -5; P<0.001). CONCLUSIONS A polypill-based strategy led to greater reductions in systolic blood pressure and LDL cholesterol level than were observed with usual care in a socioeconomically vulnerable minority population.

Massunaga, ND, França, CN, Bianco, HT, Ferreira, CES, Kato, JT, Póvoa, RMS, Figueiredo Neto, AM, Izar, MCO, Fonseca, FAH
Clinics (Sao Paulo, Brazil). 2019;:e1234
Abstract
OBJECTIVES This prospective, randomized, open-label study aimed to compare the effects of antihypertensive treatment based on amlodipine or hydrochlorothiazide on the circulating microparticles and central blood pressure values of hypertensive patients. METHODS The effects of treatments on circulating microparticles were assessed during monotherapy and after the consecutive addition of valsartan and rosuvastatin followed by the withdrawal of rosuvastatin. Each treatment period lasted for 30 days. Central blood pressure and pulse wave velocity were measured at the end of each period. Endothelial, monocyte, and platelet circulating microparticles were determined by flow cytometry. Central blood pressure values and pulse wave velocity were recorded at the end of each treatment period. RESULTS No differences in brachial blood pressure were observed between the treatment groups throughout the study. Although similar central blood pressure values were observed during monotherapy, lower systolic and diastolic central blood pressure values and early and late blood pressure peaks were observed in the amlodipine arm after the addition of valsartan alone or combined with rosuvastatin. Hydrochlorothiazide-based therapy was associated with a lower number of endothelial microparticles throughout the study, whereas a higher number of platelet microparticles was observed after rosuvastatin withdrawal in the amlodipine arm. CONCLUSIONS Despite similar brachial blood pressure values between groups throughout the study, exposure to amlodipine was associated with lower central blood pressure values after combination with valsartan, indicating a beneficial interaction. Differences between circulating microparticles were modest and were mainly influenced by rosuvastatin withdrawal in the amlodipine arm.

Abstract
BACKGROUND AND OBJECTIVES In individuals with diabetes, the comparative effectiveness of add-on antihypertensive medications added to an angiotensin-converting enzyme inhibitor or angiotensin II receptor blocker on the risk of significant kidney events is unknown. DESIGN, SETTING PARTICIPANTS, & MEASUREMENTS We used an observational, multicenter cohort of 21,897 individuals with diabetes to compare individuals who added β-blockers, dihydropyridine calcium channel blockers, loop diuretics, or thiazide diuretics to angiotensin-converting enzyme inhibitors or angiotensin II receptor blockers. We examined the hazard of significant kidney events, cardiovascular events, and death using Cox proportional hazard models with propensity score weighting. The composite significant kidney event end point was defined as the first occurrence of a ≥30% decline in eGFR to an eGFR<60 ml/min per 1.73 m2, initiation of dialysis, or kidney transplant. The composite cardiovascular event end point was defined as the first occurrence of hospitalization for acute myocardial infarction, acute coronary syndrome, stroke, or congestive heart failure; coronary artery bypass grafting; or percutaneous coronary intervention, and it was only examined in those free of cardiovascular disease at baseline. RESULTS Over a maximum of 5 years, there were 4707 significant kidney events, 1498 deaths, and 818 cardiovascular events. Compared with thiazide diuretics, hazard ratios for significant kidney events for β-blockers, calcium channel blockers, and loop diuretics were 0.81 (95% confidence interval, 0.74 to 0.89), 0.67 (95% confidence interval, 0.58 to 0.78), and 1.19 (95% confidence interval, 1.00 to 1.41), respectively. Compared with thiazide diuretics, hazard ratios of mortality for β-blockers, calcium channel blockers, and loop diuretics were 1.19 (95% confidence interval, 0.97 to 1.44), 0.73 (95% confidence interval, 0.52 to 1.03), and 1.67 (95% confidence interval, 1.31 to 2.13), respectively. Compared with thiazide diuretics, hazard ratios of cardiovascular events for β-blockers, calcium channel blockers, and loop diuretics compared with thiazide diuretics were 1.65 (95% confidence interval, 1.39 to 1.96), 1.05 (95% confidence interval, 0.80 to 1.39), and 1.55 (95% confidence interval, 1.05 to 2.27), respectively. CONCLUSIONS Compared with thiazide diuretics, calcium channel blockers were associated with a lower risk of significant kidney events and a similar risk of cardiovascular events.

Abstract
OBJECTIVE Arterial Stiffness (AS) and Non-Alcoholic Fatty Liver Diseases (NAFLD) are 2 related, prevalent, risk predictors of Cardiovascular Disease (CVD). We assessed the effect of low dose (5 mg/day) vs. high dose (20-40 mg/day) rosuvastatin on aortic elasticity and central haemodynamics as well as on NAFLD in patients with Arterial Hypertension (AH). METHODS Forty patients with optimally controlled AH were randomised to 2 rosuvastatin doses and followed for 6 months. 24h AS was assessed by Mobil-O-Graph, which calculates (adjusted for age and gender) Pulse Wave Velocity (PWV), adjusted for Heart Rate (HR) augmentation index (AIx75%) and central haemodynamics. The diagnosis of NAFLD was based on >5% liver steatosis on ultrasound and moderately elevated serum levels of liver enzymes. RESULTS Both doses of rosuvastatin reduced Central Pulse Pressure (cPP), PWV and AIx75% (adjusted for HR) to normal values (p = NS adjusted for age, gender and HR). Liver enzymes were reduced in those with NAFLD to normal, but steatosis was reduced more by the 20-40 mg/day rosuvastatin dose (p=0.01) compared with the 5 mg/day dose. CONCLUSION Both doses of rosuvastatin had a beneficial effect on AS; the high dose was more efficient in reducing PWVs and central haemodynamics, and also the high dose was more effective in ameliorating NAFLD. Given that AH control was optimal and lipid values attained targets, 4 other CVD predictors were also addressed. Larger and longer term studies are needed to demonstrate the clinical benefit of such treatment preference.
