Abstract
This multicenter, randomized, double-blind, parallel-group phase III clinical trial aimed to investigate the efficacy and safety of a rosuvastatin + amlodipine combination compared with that of rosuvastatin or amlodipine monotherapy in hypertensive patients with dyslipidemia. A total of 106 patients of 15 institutions in Korea were randomly assigned to 1 of 3 treatment groups: rosuvastatin 20 mg + amlodipine 10 mg, amlodipine 10 mg, or rosuvastatin 20 mg. After 8 weeks of treatment, the mean ± SD of change in mean sitting systolic blood pressure (msSBP) was -22.82 ± 12.99 mm Hg in the rosuvastatin + amlodipine group, the most decreased among the treatment groups. The percentage of patients whose msSBP decreased ≥20 mm Hg or msDBP decreased ≥10 mm Hg was also highest in this group (74.29%). The mean ± SD percentage change in low-density lipoprotein cholesterol (LDL-C) level from baseline after 8 weeks was -52.53% ± 11.21% in the rosuvastatin + amlodipine group, the most decreased among the treatment groups. More patients in the rosuvastatin + amlodipine group achieved their target LDL-C goal at 8 weeks, compared with the other treatment groups (97.14%). No serious adverse events or adverse drug reactions were observed in all groups. In hypertensive patients with dyslipidemia, combination treatment with rosuvastatin 20 mg + amlodipine 10 mg effectively reduced blood pressure and LDL-C levels while maintaining safety.

Abstract
This study investigated the long-term antihypertensive effects of esaxerenone, a novel nonsteroidal mineralocorticoid receptor blocker, alone or in combination with a calcium channel blocker (CCB) or a renin-angiotensin system (RAS) inhibitor, in Japanese patients with essential hypertension. Patients were treated with esaxerenone starting at 2.5 mg/day increasing to 5 mg/day if required to achieve blood pressure (BP) targets as a monotherapy or with a CCB or RAS inhibitor. After the first 12 weeks of treatment, an additional antihypertensive agent could be added if required to achieve the target BP; the total treatment period was 28 or 52 weeks. The primary endpoint was a change from baseline in sitting BP. Of the 368 enrolled patients, 245 received monotherapy, and 59 and 64, respectively, took a CCB or RAS inhibitor concurrently. Mean changes from baseline in sitting systolic/diastolic BP (95% confidence intervals) at weeks 12, 28 and 52 were -16.1 (-17.3, -14.9)/-7.7 (-8.4, -6.9), -18.9 (-20.2, -17.7)/-9.9 (-10.7, -9.2), and -23.1 (-25.0, -21.1)/-12.5 (-13.6, -11.3) mmHg, respectively (all P < 0.0001 vs baseline). Similar BP reductions at these weeks were observed between all patient subgroups stratified by age, and the observed decreases in 24-h ambulatory BP were consistent with the efficacy observed in sitting BP. Esaxerenone was also well-tolerated with a rate of hyperkalemia at 5.4% (serum potassium ≥5.5 mEq/L), indicating a good safety profile for treatment over the long-term or in combination with a CCB or RAS inhibitor. In conclusion, esaxerenone may be a promising treatment option for patients with hypertension.

Abstract
Ibrutinib is associated with dramatic efficacy against B-cell malignancies. Yet, it has been linked with potentially limiting cardiotoxicity, including emerging reports of profound hypertension (HTN). The long-term incidence, severity, and impact of HTN development with ibrutinib are unknown. Therefore, in 562 consecutive patients treated with ibrutinib for B-cell malignancies from 2009 through 2016, we assessed the new/incident or worsened HTN (systolic blood pressure [BP] cutoff, 130 mm Hg). Observed incident HTN rates were compared with Framingham-heart-predicted incident HTN rates. We also evaluated the relationship of HTN to the development of other major adverse cardiovascular events (MACEs), including arrhythmia, myocardial infarction, stroke, heart failure, and cardiovascular death. Further, we assessed the effects of different antihypertensive classes on ibrutinib-related HTN. Overall, 78.3% of ibrutinib users developed new or worsened HTN over a median of 30 months. New HTN developed in 71.6% of ibrutinib users, with a time to 50% cumulative incidence of 4.2 months. Among those without preceding HTN, 17.7% developed high-grade HTN (BP >160/100 mm Hg). In multivariate regression, new or worsened HTN was associated with increased MACEs (hazard ratio [HR], 2.17; 95% confidence interval [CI], 1.08-4.38). No single antihypertensive class was associated with prevention or control of ibrutinib-related HTN. However, antihypertensive initiation was associated with a lower risk of a MACE (HR, 0.40; 95% CI, 0.24-0.66). Collectively, these data suggest that ibrutinib is associated with a substantial increase in the incidence and severity of HTN, and that HTN development carries a higher risk of subsequent cardiotoxic events.

Abstract
We conducted a discovery genome-wide association study with expression quantitative trait loci (eQTL) annotation of new-onset diabetes (NOD) among European Americans, who were exposed to a calcium channel blocker-based strategy (CCB strategy) or a β-blocker-based strategy (β-blocker strategy) in the INternational VErapamil SR Trandolapril STudy. Replication of the top signal from the SNP*treatment interaction analysis was attempted in Hispanic and African Americans, and a joint meta-analysis was performed (total 334 NOD cases and 806 matched controls). PLEKHH2 rs11124945 at 2p21 interacted with antihypertensive exposure for NOD (meta-analysis P=5.3 × 10-8). rs11124945 G allele carriers had lower odds for NOD when exposed to the β-blocker strategy compared with the CCB strategy (Odds ratio OR=0.38(0.24-0.60), P=4.0 × 10-5), whereas A/A homozygotes exposed to the β-blocker strategy had increased odds for NOD compared with the CCB strategy (OR=2.02(1.39-2.92), P=2.0 × 10-4). eQTL annotation of the 2p21 locus provides functional support for regulating gene expression.

Abstract
The thiazide-sensitive NaCl cotransporter (NCC), located apically in distal convoluted tubule epithelia, regulates the fine-tuning of renal sodium excretion. Three isoforms of NCC are generated through alternative splicing of the transcript, of which the third isoform has been the most extensively investigated in pathophysiological conditions. The aim of this study was to investigate the effect of different anti-hypertensive treatments on the abundance and phosphorylation of all three NCC isoforms in urinary extracellular vesicles (uEVs) of essential hypertensive patients. In uEVs isolated from patients (n = 23) before and after hydrochlorothiazide or valsartan treatment, the abundance and phosphorylation of the NCC isoforms was determined. Additionally, clinical biochemistry and blood pressure of the patients was assessed. Our results show that NCC detected in human uEVs has a glycosylated and oligomeric structure, comparable to NCC present in human kidney membrane fractions. Despite the inhibitory action of hydrochlorothiazide on NCC activity, immunoblot analysis of uEVs showed significantly increased abundance of NCC isoforms 1 and 2 (NCC1/2), total NCC (NCC1-3), and the phosphorylated form of total NCC (pNCC1-3-T55/T60) in essential hypertensive patients treated with hydrochlorothiazide but not with valsartan. This study highlights that NCC1/2, NCC1-3, and pNCC1-3-T55/T60 are upregulated by hydrochlorothiazide, and the increase in NCC abundance in uEVs of essential hypertensive patients correlates with the blood pressure response to hydrochlorothiazide.

Abstract
BACKGROUND Intensive blood pressure (BP) treatment can avert cardiovascular disease (CVD) events but can cause some serious adverse events. We sought to develop and validate risk models for predicting absolute risk difference (increased risk or decreased risk) for CVD events and serious adverse events from intensive BP therapy. A secondary aim was to test if the statistical method of elastic net regularization would improve the estimation of risk models for predicting absolute risk difference, as compared to a traditional backwards variable selection approach. METHODS AND FINDINGS Cox models were derived from SPRINT trial data and validated on ACCORD-BP trial data to estimate risk of CVD events and serious adverse events; the models included terms for intensive BP treatment and heterogeneous response to intensive treatment. The Cox models were then used to estimate the absolute reduction in probability of CVD events (benefit) and absolute increase in probability of serious adverse events (harm) for each individual from intensive treatment. We compared the method of elastic net regularization, which uses repeated internal cross-validation to select variables and estimate coefficients in the presence of collinearity, to a traditional backwards variable selection approach. Data from 9,069 SPRINT participants with complete data on covariates were utilized for model development, and data from 4,498 ACCORD-BP participants with complete data were utilized for model validation. Participants were exposed to intensive (goal systolic pressure < 120 mm Hg) versus standard (<140 mm Hg) treatment. Two composite primary outcome measures were evaluated: (i) CVD events/deaths (myocardial infarction, acute coronary syndrome, stroke, congestive heart failure, or CVD death), and (ii) serious adverse events (hypotension, syncope, electrolyte abnormalities, bradycardia, or acute kidney injury/failure). The model for CVD chosen through elastic net regularization included interaction terms suggesting that older age, black race, higher diastolic BP, and higher lipids were associated with greater CVD risk reduction benefits from intensive treatment, while current smoking was associated with fewer benefits. The model for serious adverse events chosen through elastic net regularization suggested that male sex, current smoking, statin use, elevated creatinine, and higher lipids were associated with greater risk of serious adverse events from intensive treatment. SPRINT participants in the highest predicted benefit subgroup had a number needed to treat (NNT) of 24 to prevent 1 CVD event/death over 5 years (absolute risk reduction [ARR] = 0.042, 95% CI: 0.018, 0.066; P = 0.001), those in the middle predicted benefit subgroup had a NNT of 76 (ARR = 0.013, 95% CI: -0.0001, 0.026; P = 0.053), and those in the lowest subgroup had no significant risk reduction (ARR = 0.006, 95% CI: -0.007, 0.018; P = 0.71). Those in the highest predicted harm subgroup had a number needed to harm (NNH) of 27 to induce 1 serious adverse event (absolute risk increase [ARI] = 0.038, 95% CI: 0.014, 0.061; P = 0.002), those in the middle predicted harm subgroup had a NNH of 41 (ARI = 0.025, 95% CI: 0.012, 0.038; P < 0.001), and those in the lowest subgroup had no significant risk increase (ARI = -0.007, 95% CI: -0.043, 0.030; P = 0.72). In ACCORD-BP, participants in the highest subgroup of predicted benefit had significant absolute CVD risk reduction, but the overall ACCORD-BP participant sample was skewed towards participants with less predicted benefit and more predicted risk than in SPRINT. The models chosen through traditional backwards selection had similar ability to identify absolute risk difference for CVD as the elastic net models, but poorer ability to correctly identify absolute risk difference for serious adverse events. A key limitation of the analysis is the limited sample size of the ACCORD-BP trial, which expanded confidence intervals for ARI among persons with type 2 diabetes. Additionally, it is not possible to mechanistically explain the physiological relationships explaining the heterogeneous treatment effects captured by the models, since the study was an observational secondary data analysis. CONCLUSIONS We found that predictive models could help identify subgroups of participants in both SPRINT and ACCORD-BP who had lower versus higher ARRs in CVD events/deaths with intensive BP treatment, and participants who had lower versus higher ARIs in serious adverse events.

Low-Sodium Versus Standard-Sodium Peritoneal Dialysis Solution in Hypertensive Patients: A Randomized Controlled Trial.
Rutkowski, B, Tam, P, van der Sande, FM, Vychytil, A, Schwenger, V, Himmele, R, Gauly, A, ,
American journal of kidney diseases : the official journal of the National Kidney Foundation. 2016;(5):753-61
Abstract
BACKGROUND Peritoneal dialysis (PD) solutions with reduced sodium content may have advantages for hypertensive patients; however, they have lower osmolarity and solvent drag, so the achieved Kt/Vurea may be lower. Furthermore, the increased transperitoneal membrane sodium gradient can influence sodium balance with consequences for blood pressure (BP) control. STUDY DESIGN Prospective, randomized, double-blind clinical trial to prove the noninferiority of total weekly Kt/Vurea with low-sodium versus standard-sodium PD solution, with the lower confidence limit above the clinically accepted difference of -0.5. SETTING & PARTICIPANTS Hypertensive patients (≥ 1 antihypertensive drug, including diuretics, or office systolic BP ≥ 130 mmHg) on continuous ambulatory PD therapy from 17 sites. INTERVENTION 108 patients were randomly assigned (1:1) to 6-month treatments with either low-sodium (125 mmol/L of sodium; 1.5%, 2.3%, or 4.25% glucose; osmolarity, 338-491 mOsm/L) or standard-sodium (134 mmol/L of sodium; 1.5%, 2.3%, or 4.25% glucose; osmolarity, 356-509 mOsm/L) PD solution. OUTCOMES Primary end point: weekly total Kt/Vurea; secondary outcomes: BP control, safety, and tolerability. MEASUREMENTS Total Kt/Vurea was determined from 24-hour dialysate and urine collection; BP, by office measurement. RESULTS Total Kt/Vurea after 12 weeks was 2.53 ± 0.89 in the low-sodium group (n = 40) and 2.97 ± 1.58 in the control group (n = 42). The noninferiority of total Kt/Vurea could not be confirmed. There was no difference for peritoneal Kt/Vurea (1.70 ± 0.38 with low sodium, 1.77 ± 0.44 with standard sodium), but there was a difference in renal Kt/Vurea (0.83 ± 0.80 with low sodium, 1.20 ± 1.54 with standard sodium). Mean daily sodium removal with dialysate at week 12 was 1.188 g higher in the low-sodium group (P < 0.001). BP changed marginally with standard-sodium solution, but decreased with low-sodium PD solution, resulting in less antihypertensive medication. LIMITATIONS Broader variability of study population than anticipated, particularly regarding residual kidney function. CONCLUSIONS The noninferiority of the low-sodium PD solution for total Kt/Vurea could not be proved; however, it showed beneficial clinical effects on sodium removal and BP.

Abstract
BACKGROUND Dietary nitrate, which is in green leafy vegetables and beetroot, decreases blood pressure through the enterosalivary nitrate-nitrite-nitric oxide pathway in healthy individuals. Whether similar effects would occur in individuals with treated hypertension and, therefore, at increased risk of cardiovascular disease is unclear. OBJECTIVE We assessed whether increased dietary nitrate intake by using beetroot juice for 1 wk lowers blood pressure in treated hypertensive men and women. DESIGN Participants (n = 27) were recruited to a randomized, placebo-controlled, double-blind crossover trial. The effect of 1-wk intake of nitrate-rich beetroot juice was compared with 1-wk intake of nitrate-depleted beetroot juice (placebo). The primary outcome was blood pressure assessed by measuring home blood pressure during the intervention and 24-h ambulatory blood pressure on day 7 of the intervention. Other outcomes included nitrate metabolism assessed by measuring nitrate and nitrite in plasma, saliva, and urine. RESULTS Relative to the placebo, 1-wk intake of nitrate-rich beetroot juice resulted in a 3-fold increase in plasma nitrite and nitrate, a 7-fold increase in salivary nitrite, an 8-fold higher salivary nitrate, and a 4-fold increase in both urinary nitrite and nitrate (P < 0.001). However, no differences in home blood pressure and 24-h ambulatory blood pressure were observed with 1-wk intake of nitrate-rich beetroot juice in comparison with the placebo. CONCLUSION An increase in dietary nitrate intake may not be an effective short-term approach to further lower blood pressure in treated hypertensive subjects.

Abstract
BACKGROUND Paracetamol's solubility is achieved by adding to the excipient sodium salts, either as bicarbonate, carbonate or citrate. As the relationship between salt and hypertension is well known, due to the sodium content it has raised a hypothesis that may interfere with the control of that risk factor. Therefore, the objective of this study is to evaluate the effect on blood pressure of effervescent paracetamol compared to non-effervescent, in hypertensive patients. METHODS/DESIGN This is the protocol of a phase IV multicenter clinical trial, randomized, controlled, crossover, open, which will compare the effect of two different formulations of paracetamol (effervescent or non-effervescent) in the blood pressure of hypertensive patients, with a seven weeks follow up. 49 controlled hypertensive patients will be included (clinical BP lower than 150 and 95 mmHg, and lower than 135 mmHg and 85 mmHg in patients with diabetes or a history of cardiovascular event, and daytime ambulatory measurements lower than 140 and 90 mmHg) and mild to moderate pain (Visual Analog Scale between 1 and 4). The study was approved by the ethics committee of the Fundació Jordi Gol i Gurina and following standards of good clinical practice. The primary endpoint will be the variations in systolic BP in 24 h Ambulatory Blood Pressure Monitoring, considering significant differences 2 or more mmHg among those treated with non-effervescent and effervescent formulations. Intention-to-treat and per-protocol analysis will be held. DISCUSSION Despite the broad recommendation not to use effervescent drugs in patients with hypertension, there are relatively little studies that show exactly this pressor effect due to sodium in salt that gives the effervescence of the product. This is the first clinical trial designed to study the effect of effervescence compared to the non-effervescent, in well-controlled hypertensive patients with mild to moderate pain, performed in routine clinical practice. TRIAL REGISTRATION NCT 02514538.

Abstract
INTRODUCTION We investigated the possibilities of drug-drug interactions between luseogliflozin, a sodium-glucose co-transporter-2 inhibitor, and oral antidiabetic drugs (OADs) in healthy Japanese males. METHODS We conducted six independent studies to investigate potential drug-drug interactions between 5 mg luseogliflozin and the following OADs usually used in Japan: 1 mg glimepiride, 250 mg metformin, 30 mg pioglitazone, 50 mg sitagliptin, 50 mg miglitol, or 0.6 mg voglibose (0.2 mg before each meal). Twelve subjects were enrolled in each study. The glimepiride, metformin, sitagliptin, and miglitol studies were randomized, open-label, single-dose, three-way crossover studies. The pioglitazone and voglibose studies were open-label studies, where a single dose of luseogliflozin was added to multiple doses of pioglitazone or voglibose. The endpoints were the area under the curve from 0 to 24 h (AUC0-24 h) or to infinity (AUCinf) and the maximum concentration (Cmax) of each drug administered alone or in combination. RESULTS The 90% confidence intervals (CIs) of the geometric mean ratio (GMR) for Cmax of luseogliflozin in the pioglitazone and miglitol studies were beyond the reference range for bioequivalence (0.80-1.25) (miglitol: 0.851 [0.761, 0.952]; pioglitazone: 1.16 [1.04, 1.30]). However, the 90% CIs for AUC0-24 h were within the reference range. The 90% CIs of the GMRs for Cmax and AUC0-24 h of pioglitazone were beyond the reference range (Cmax 0.884 [0.746, 1.05]; AUC0-24 h 0.896 [0.774, 1.04]), but the 90% CIs for the active metabolites of pioglitazone were within the reference range. For the other combinations tested, the 90% CIs and GMRs for luseogliflozin and the individual OADs were within the reference range. CONCLUSION No clinically meaningful interactions were observed between luseogliflozin and six commonly used OADs in Japan, although there were some changes in the pharmacokinetics of pioglitazone co-administered with luseogliflozin and for luseogliflozin co-administered with miglitol or pioglitazone.
