Project description:Angiotensin-converting enzyme inhibitors and angiotensin receptor blockers (ACEI/ARB) are the first-line drugs for the treatment of essential hypertension (HTN), one of the most important risk factors for cardiovascular and cerebrovascular diseases. Intestinal flora and microbial metabolites have been demonstrated to play important roles in blood pressure (BP) regulation and HTN development. However, it remains elusive that intestinal bacteria and metabolites are associated with the protective effects of ACEI/ARB anti-hypertensive drugs against HTN. In this study, we evaluated the effect of ACEI/ARB on gut microbiome and metabolites in patients suffering from HTN. We performed 16S rRNA sequencing and fecal metabolomic analysis of 36 HTN patients placed on ACEI/ARB therapy and 19 newly diagnosed HTN patients with no history of anti-hypertensive treatment. Patients under medication treatment were further classified into well-controlled (n = 24) and poor-controlled (n = 12) groups according to their BP levels. The ACEI/ARB improved the intestinal microbiome of the HTN patients by reducing potentially pathogenic bacteria such as Enterobacter and Klebsiella and increasing beneficial bacteria such as Odoribacter. Moreover, ACEI/ARB therapy was correlated with significant metabolomic changes in the HTN patients, including progressively enhanced inositol from poor-controlled to well-controlled groups. The profiles of gut bacteria were linked to the production of metabolites, and inositol was negatively correlated with Klebsiella, Enterobacter, and Proteobacteria. Our study suggests that ACEI/ARB modulates gut microbial composition and functions and alters microbial metabolites in HTN patients.

Project description:Angiotensin receptor blockade (ARB) and sodium-glucose co-transporter 2 inhibitor (SGLT2i) have been used as the standard therapy for patients with diabetic kidney disease (DKD). However, how these two drugs possess additive renal protective effects remains unclear. Here, we conducted single cell RNA-sequencing to profile the kidney cell transcriptome of db/db mice treated with vehicle, ARB, SGLT2i, or both drugs and db/m mice. We identified 10 distinct clusters of kidney cells with predominant proximal tubular (PT) cells. We found that ARB has more anti-inflammatory and anti-fibrosis effects while SGLT2i affects more mitochondrial function. We also identified a new PT subcluster which was increased in DKD but reversed by treatments.This new subcluster was also confirmed by Immunostaining of mouse and human kidneys with DKD. Together, our study reveal kidney cell-specific gene signatures in response to ARB and SGLT2i and also identified a new PT subcluster which provides new insight into DKD.

Project description:ObjectiveIn order to search for metabolic biomarkers of antihypertensive drug responsiveness, we measured >600 biochemicals in plasma samples of subjects participating in the GENRES Study. Hypertensive men received in a double-blind rotational fashion amlodipine, bisoprolol, hydrochlorothiazide and losartan, each as a monotherapy for one month, with intervening one-month placebo cycles.MethodsMetabolomic analysis was carried out using ultra high performance liquid chromatography-tandem mass spectrometry. Full metabolomic signatures (the drug cycles and the mean of the 3 placebo cycles) became available in 38 to 42 patients for each drug. Blood pressure was monitored by 24-h recordings.ResultsAmlodipine (P values down to 0.002), bisoprolol (P values down to 2 x 10-5) and losartan (P values down to 2 x 10-4) consistently decreased the circulating levels of long-chain acylcarnitines. Bisoprolol tended to decrease (P values down to 0.002) the levels of several medium- and long-chain fatty acids. Hydrochlorothiazide administration was associated with an increase of plasma uric acid level (P = 5 x 10-4) and urea cycle metabolites. Decreases of both systolic (P = 0.06) and diastolic (P = 0.04) blood pressure after amlodipine administration tended to associate with a decrease of plasma hexadecanedioate, a dicarboxylic fatty acid recently linked to blood pressure regulation.ConclusionsAlthough this systematic metabolomics study failed to identify circulating metabolites convincingly predicting favorable antihypertensive response to four different drug classes, it provided accumulating evidence linking fatty acid metabolism to human hypertension.

Project description:BackgroundIn a free drug combination, each Blood pressure (BP)-lowering drug is administered as a separate pill, while in a fixed drug combination several BP-lowering agents are combined in a single pill. Using a single pill may enhance compliance and simplify treatment, which would translate into better clinical outcomes. The objective of this meta-analysis is to compare the effects of using a fixed combination versus free combination of BP-lowering agents in the management of patients with essential hypertension.MethodsWe searched Cochrane CENTRAL, MEDLINE, and EMBASE for randomized clinical trials (RCTs) addressing the objective of the review and assessing at least one of the following outcomes: BP-lowering efficacy, rapidity in achieving BP target, compliance, incidence of side effects, mortality, and morbidity. Two review authors independently selected eligible studies, abstracted data, and assessed risk of bias of included trials. The primary meta-analyses used a random-effects model.ResultsWe identified seven RCTs with a total of 397 participants. Meta-analysis of efficacy in controlling BP showed a non-significant reduction of mean systolic BP of 0.81 mmHg (95% CI -3.25, 1.64) favoring the fixed combination group. As for adverse events, results showed a non-significant 13% risk reduction favoring the free combination (risk ratio 1.13, 95% CI 0.85, 1.5). Low quality of evidence was noted for both outcomes. Rapidity in achieving BP target was assessed in only one trial, and the results favored the fixed combination. Adherence to treatment was assessed in three trials, no pooled analysis was possible for this outcome. None of the included trials assessed mortality and morbidity.ConclusionThe available low quality evidence does not confirm or rule out a substantive difference between fixed combination and free combination therapy in the management of HTN. Well designed RCTs with a long duration of follow-up and assessment of morbidity and mortality outcomes are needed.

Project description:BackgroundIncreasing evidence have indicated the relationship between intestinal dysbiosis and hypertension. We aimed to evaluate the effect of the electroacupuncture (EA) on intestinal microbiota in patients with stage 1 hypertension.Methods93 hypertensive patients and 15 healthy subjects were enrolled in this study. Applying a highly accurate oscillometric device to evaluate the antihypertensive effect of EA. 16S rRNA sequencing was used to profile stool microbial communities from Healthy group, Before treatment (BT) group and After treatment (AT) group, and various multivariate analysis approaches were used to assess diversity, composition and abundance of intestinal microbiota.ResultsIn this study, EA significantly decreased the blood pressure (BP) of hypertensive patients. Higher abundance of Firmicutes and lower Bacteroidetes abundance were observed in the BT group compared to the Healthy group. And EA treatment significantly decreased the Firmicutes/Bacteroidetes ratio compared to the BT group. Moreover, at the genus level, there was an increased abundance of Escherichia-Shigella in patients with hypertension, while Blautia were decreased, and EA reversed these changes.ConclusionsOur study indicates that EA can effectively lower BP and improve the structure of intestinal microbiota which are correlate with the alteration of blood pressure by electroacupuncture.Trial registrationClinicaltrial.gov, NCT01701726.

Project description:BackgroundDifferent antihypertensive therapies (especially diuretics) are reported to induce the new onset of diabetes in some hypertensive patients. α-adducin-1 (ADD1) gene is salt sensitive gene which has its role in etiology of hypertension via salt sensitivity. Therefore, the G460T polymorphism of ADD1 gene may be associated with new onset of diabetes under the influence of diuretic and other antihypertensive therapies.AimTo assess the correlation between genetic polymorphism (ADD1 G460T polymorphism) and glycaemic disturbance under influence of diuretic and other antihypertensive drug therapies.Materials and methodsWe recruited study subjects, 270 normotensive as control (150 male and 120 females), 270 hypertensive patients (95 male and 175 females) and 240 hypertensive with new onset of diabetes patients (80 male and 160 females). All study samples were genotyped for ADD1 polymorphic alleles and analyzed the relationship between different genotypes with respect to anthropometric and clinical parameters along with drug therapies.ResultsClinical and anthropometric parameters (such as age, SBP, DBP, FBG, height, weight, WC, HP, W/H ratio, and BMI) of study population were found highly statistically significant (p<0.05) at base value. Further, genotype wise comparison of all the above parameters revealed most of them as non-significant (p>0.05). Whereas, comparison between genotype and different antihypertensive drug therapy of hypertensive patients, specifically, diuretic therapy as mono in male (p=0.0227) and female (p=0.0292) and in combination with BBs in both male (p=0.0023) and female (p=0.0079) revealed a higher FBG level in variant T allele. In case of hypertensive with new onset of diabetes patients, only female population showed a slightly statistically significant (p=0.0413) difference in FBG level with diuretic mono therapy. Other antihypertensive drug therapies were safe and effective either as mono or in combination therapy.DiscussionAnthropometric parameters may be the indicative factors for hypertension and diabetes. Variant T allele of ADD1 gene may be considered as the risk factor for the development of diabetes in hypertensive patients. Diuretics as mono therapy and in combination with BBs may be considered as the risk factor for new onset of diabetes in EH patients carrying variant T allele (either as TG or TT).

Project description:ObjectiveTo investigate the relationships among aldosterone level, use of antihypertensive (anti-HTN) medications, clinical profile, and atrial natriuretic peptide (ANP) level in individuals with HTN.Participants and methodsIn a community-based cohort, we analyzed aldosterone plasma levels based on the presence (n=477) or absence (n=1073) of HTN. In individuals with HTN, we evaluated circulating aldosterone levels according to the number of anti-HTN drugs used, analyzed the associated clinical characteristics, and determined the relationship to the counterregulatory cardiac hormone ANP. Data were collected from August 25, 1997, through September 5, 2000.ResultsParticipants with HTN had higher serum aldosterone levels than those without HTN (6.4 vs 4.1 ng/dL [to convert to pmol/L, multiply by 27.74]; P<.001). When individuals with HTN were stratified according to the number of anti-HTN medications used, the increase in number of medications (0, 1, 2, and ≥3) was associated with higher aldosterone levels (4.8, 6.4, 7.10, and 7.9 ng/dL, respectively; P=.002), worse metabolic profile, and higher prevalence of cardiovascular, renal, and metabolic disease. In participants with HTN, ANP plasma levels were inversely related to aldosterone levels when the latter was divided into tertiles.ConclusionIn this randomly selected general population cohort, aldosterone levels were higher in individuals with HTN compared with normotensive participants. Aldosterone levels increased with anti-HTN medication use. These findings also suggest a relative ANP deficiency with increasing aldosterone levels and anti-HTN drug use. These studies have pathophysiologic and therapeutic implications for targeting aldosterone in the clinical treatment of HTN.
