Cluster analysis of angiotensin biomarkers to identify antihypertensive drug treatment in population studies. BMC Med Res Methodol 2023; 23:131. [PMID: 37245005 PMCID: PMC10224304 DOI: 10.1186/s12874-023-01930-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/20/2023] [Accepted: 04/23/2023] [Indexed: 05/29/2023] Open
Abstract
BACKGROUND The recent progress in molecular biology generates an increasing interest in investigating molecular biomarkers as markers of response to treatments. The present work is motivated by a study, where the objective was to explore the potential of the molecular biomarkers of renin-angiotensin-aldosterone system (RAAS) to identify the undertaken antihypertensive treatments in the general population. Population-based studies offer an opportunity to assess the effectiveness of treatments in real-world scenarios. However, lack of quality documentation, especially when electronic health record linkage is unavailable, leads to inaccurate reporting and classification bias. METHOD We present a machine learning clustering technique to determine the potential of measured RAAS biomarkers for the identification of undertaken treatments in the general population. The biomarkers were simultaneously determined through a novel mass-spectrometry analysis in 800 participants of the Cooperative Health Research In South Tyrol (CHRIS) study with documented antihypertensive treatments. We assessed the agreement, sensitivity and specificity of the resulting clusters against known treatment types. Through the lasso penalized regression, we identified clinical characteristics associated with the biomarkers, accounting for the effects of cluster and treatment classifications. RESULTS We identified three well-separated clusters: cluster 1 (n = 444) preferentially including individuals not receiving RAAS-targeting drugs; cluster 2 (n = 235) identifying angiotensin type 1 receptor blockers (ARB) users (weighted kappa κw = 74%; sensitivity = 73%; specificity = 83%); and cluster 3 (n = 121) well discriminating angiotensin-converting enzyme inhibitors (ACEi) users (κw = 81%; sensitivity = 55%; specificity = 90%). Individuals in clusters 2 and 3 had higher frequency of diabetes as well as higher fasting glucose and BMI levels. Age, sex and kidney function were strong predictors of the RAAS biomarkers independently of the cluster structure. CONCLUSIONS Unsupervised clustering of angiotensin-based biomarkers is a viable technique to identify individuals on specific antihypertensive treatments, pointing to a potential application of the biomarkers as useful clinical diagnostic tools even outside of a controlled clinical setting.

Abstract
Aldosterone exerts profound effects on renal and cardiovascular physiology. In the kidney, aldosterone acts to preserve electrolyte and acid-base balance in response to changes in dietary sodium (Na+ ) or potassium (K+ ) intake. These physiological actions, principally through activation of mineralocorticoid receptors (MRs), have important effects particularly in patients with renal and cardiovascular disease as demonstrated by multiple clinical trials. Multiple factors, be they genetic, humoral, dietary, or otherwise, can play a role in influencing the rate of aldosterone synthesis and secretion from the adrenal cortex. Normally, aldosterone secretion and action respond to dietary Na+ intake. In the kidney, the distal nephron and collecting duct are the main targets of aldosterone and MR action, which stimulates Na+ absorption in part via the epithelial Na+ channel (ENaC), the principal channel responsible for the fine-tuning of Na+ balance. Our understanding of the regulatory factors that allow aldosterone, via multiple signaling pathways, to function properly clearly implicates this hormone as central to many pathophysiological effects that become dysfunctional in disease states. Numerous pathologies that affect blood pressure (BP), electrolyte balance, and overall cardiovascular health are due to abnormal secretion of aldosterone, mutations in MR, ENaC, or effectors and modulators of their action. Study of the mechanisms of these pathologies has allowed researchers and clinicians to create novel dietary and pharmacological targets to improve human health. This article covers the regulation of aldosterone synthesis and secretion, receptors, effector molecules, and signaling pathways that modulate its action in the kidney. We also consider the role of aldosterone in disease and the benefit of mineralocorticoid antagonists. © 2023 American Physiological Society. Compr Physiol 13:4409-4491, 2023.

Abstract
BACKGROUND Sex differences in the antihypertensive medications used to control blood pressure and risk factor control in hypertensive patients is poorly understood. METHODS We conducted a retrospective review of the patients newly diagnosed with hypertension registered for treatment in 52 outpatient settings across Abu Dhabi province between 1 January and 31 December 2017. We explored sex differences in risk factors and treatment management over 6 months of the follow-up period of each patient. Multiple logistic regression models were used to identify factors associated with poor BP control. RESULTS A total of 5308 patients (2559 men and 2849 women) were identified. We observed an increase in SBP and DBP levels in men (1.72/1.13 mmHg) and only SBP in women (0.87/-0.021 mmHg) with increased incidence of comorbidities overtime. The overall BP control was suboptimal (65%) (<140/90 mmHg) with no significant difference between women (65.3%) and men (64.2%). In men with dyslipidemia, use of angiotensin-converting enzyme inhibitor or angiotensin receptor blocker with diuretics and in women, only calcium channel blockers showed higher for BP control. Factors significantly associated with poor BP control in men are being overweight and obese, and dyslipidemia in men. After the age of 50, women in contrast to men, with dyslipidemia and heart rate >80 beats per minute are less likely to maintain hypertension control. CONCLUSION Sex-specific analysis indicated that BP control among United Arab Emirates men and women was suboptimal (65%). Interventions aiming to achieve better control of BP in hypertensive patients with metabolic syndrome should be emphasized.

Positive association of angiotensin II receptor blockers, not angiotensin-converting enzyme inhibitors, with an increased vulnerability to SARS-CoV-2 infection in patients hospitalized for suspected COVID-19 pneumonia. PLoS One 2020; 15:e0244349. [PMID: 33347477 PMCID: PMC7751849 DOI: 10.1371/journal.pone.0244349] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/22/2020] [Accepted: 12/08/2020] [Indexed: 01/19/2023] Open
Abstract
Background Angiotensin-converting enzyme 2 is the receptor that severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) uses for entry into lung cells. Because ACE-2 may be modulated by angiotensin-converting enzyme inhibitors (ACEIs) and angiotensin II receptor blockers (ARBs), there is concern that patients treated with ACEIs and ARBs are at higher risk of coronavirus disease 2019 (COVID-19) pneumonia. Aim This study sought to analyze the association of COVID-19 pneumonia with previous treatment with ACEIs and ARBs. Materials and methods We retrospectively reviewed 684 consecutive patients hospitalized for suspected COVID-19 pneumonia and tested by polymerase chain reaction assay. Patients were split into two groups, according to whether (group 1, n = 484) or not (group 2, n = 250) COVID-19 was confirmed. Multivariable adjusted comparisons included a propensity score analysis. Results The mean age was 63.6 ± 18.7 years, and 302 patients (44%) were female. Hypertension was present in 42.6% and 38.4% of patients in groups 1 and 2, respectively (P = 0.28). Treatment with ARBs was more frequent in group 1 than group 2 (20.7% vs. 12.0%, respectively; odds ratio [OR] 1.92, 95% confidence interval [CI] 1.23–2.98; P = 0.004). No difference was found for treatment with ACEIs (12.7% vs. 15.7%, respectively; OR 0.81, 95% CI 0.52–1.26; P = 0.35). Propensity score-matched multivariable logistic regression confirmed a significant association between COVID-19 and previous treatment with ARBs (adjusted OR 2.36, 95% CI 1.38–4.04; P = 0.002). Significant interaction between ARBs and ACEIs for the risk of COVID-19 was observed in patients aged > 60 years, women, and hypertensive patients. Conclusions This study suggests that ACEIs and ARBs are not similarly associated with COVID-19. In this retrospective series, patients with COVID-19 pneumonia more frequently had previous treatment with ARBs compared with patients without COVID-19.

Abstract
Increased sympathetic nervous system (SNS) activity leads to increased risk of cardiovascular morbidity and mortality. This study investigated whether there were sex differences in SNS activity among Chinese patients with hypertension. Ethnic Chinese non‐diabetic hypertensive patients aged 20–50 years were enrolled in Taiwan. A total of 970 hypertensive patients (41.0 ± 7.2 years) completed the study, 664 men and 306 women. They received comprehensive evaluations including office blood pressure (BP) measurement, 24‐h ambulatory BP monitoring, and 24‐h urine sampling assayed for catecholamine excretion. Compared to women, men were younger, had higher body mass index (BMI), office systolic BP (SBP), office diastolic BP (DBP), 24‐h ambulatory BP, and 24‐h urine catecholamine excretion. In men, 24‐h urine total catecholamine levels were correlated with 24‐h SBP (r = 0.103, p = .008) and 24‐h DBP (r = 0.083, p = .033). In women, however, there was no correlation between 24‐h urine total catecholamine levels and 24‐h ambulatory BP. Multivariate linear regression indicated that being male (β = 1.65, 95% confidence interval [CI] 0.01–3.29, p = .048) and 24‐h urine total catecholamine (β = 5.03, 95% CI 0.62–9.44, p = .025) were both independently associated with 24‐h SBP; being male was independently associated with 24‐h DBP (β = 3.55, 95% CI 2.26–4.85, p < .001). In conclusion, Chinese men with hypertension had higher SNS activity than women, and SNS activity was independently associated with 24‐h ambulatory BP in men rather than in women. These findings suggest that different hypertensive treatment strategies should be considered according to patient sex.

Abstract
BACKGROUND Cardiovascular diseases are still the major cause of death in the Western world, with different outcomes between the two genders. Efforts to identify those at risk are therefore given priority in the handling of health resources. Thrombospondins (TSP) are extracellular matrix proteins associated with cardiovascular diseases. The aim of this study was to investigate variations in single nucleotide polymorphisms (SNPs) of TSP-1 and plasma expression, and associations with mortality from a gender perspective. METHODS A population of 470 community-living persons were invited to participate. The participants were followed for 7.9 years and underwent a clinical examination and blood sampling. SNP analyses of TSP-1 rs1478604 and rs2228262 using allelic discrimination and plasma measurement of TSP-1 using ELISA were performed, RESULTS: During the follow-up period, 135 (28.7%) all-cause and 83 (17.7%) cardiovascular deaths were registered. In the female population, the A/A genotype of rs2228262 and the T/T genotype of rs1478604 exhibited significantly more cardiovascular deaths compared with the A/G and G/G, or the T/C and C/C genotypes amalgamated (rs2228262: 13.7% vs 2.0%; Χ2:5.29; P = 0.02; rs1478604:17.7% vs 4.7%; Χ2:9.50; P = 0.002). Applied in a risk evaluation, the A/A, or T/T genotypes exhibited an increased risk of cardiovascular mortality (rs2228262: HR: 7.1; 95%CI 1.11-45.8; P = 0.04; rs1478604: HR: 3.18; 95%CI 1.35-7.50; p = 0.008). No differences among the three genotypes could be seen in the male group. CONCLUSION In this study the female group having the A/A genotype of rs2228262, or the T/T genotype of rs1478604 of TSP-1 exhibited higher cardiovascular mortality after a follow-up of almost 8 years. No corresponding genotype differences could be found in the male group. Genotype evaluations should be considered as one of the options to identify individuals at risk. However, this study should be regarded as hypothesis-generating, and more research in the field is needed.

Abstract
BACKGROUND Hypertension is the most important modifiable cardiovascular risk factor. Epidemiological studies have shown the benefits of lowering blood pressure (BP), but BP control is a major challenge. Furthermore, there are significant sex differences in antihypertensive drug use and BP control. This study examined sex differences in antihypertensive drug use and BP control, with the aim of reducing the complications of hypertension and improving quality of life. METHODS The study was performed in our outpatient hypertension clinic, and included 1529 patients without secondary hypertension or comorbidities. The study, investigated BP control rates and patterns of antihypertensive drug use in male and female. All data were collected using structured questionnaires and patient measurements. RESULTS The study included 713 males and 816 females in this study. Fewer females had hypertension in the younger age group (16.2% vs 11.6%; p>0.05), but this difference disappeared in middle-aged (47.8% vs 49.9 %; p<0.05) and elderly age groups (36.0% vs 38.5%; p<0.05). BP control rates differed between males and females (35.6% in male, 31.9% in female, p<0.01). There was an overall difference in BP control rates between males and females (35.6% in males, 31.9% in females, p<0.01). In this aged 18-44 years, angiotensin converting enzyme inhibitors (ACEIs) showed the best control rate in males, while calcium channel blockers (CCBs) were least effective (61.5% with ACEIs, 28.6% with CCBs; p<0.05). In this aged 45-64 years, diuretics (DUs) showed the best control rate in females, while CCBs were least effective (47.5% with DUs, 28.3% with CCBs; p<0.05). CONCLUSIONS Sex plays an important role in BP control. In those aged 18-44 years, males using ACEIs showed best control rates. In those aged 45-64 years, females using DUs showed best control rates. Our study provides a basis with the selection of antihypertensive drugs according to sex and age.

Abstract
The thick ascending limb plays a key role in maintaining water and electrolyte balance. The importance of this segment in regulating blood pressure is evidenced by the effect of loop diuretics or local genetic defects on this parameter. Hormones and factors produced by thick ascending limbs have both autocrine and paracrine effects, which can extend prohypertensive signaling to other structures of the nephron. In this review, we discuss the role of the thick ascending limb in the development of hypertension, not as a sole participant, but one that works within the rich biological context of the renal medulla. We first provide an overview of the basic physiology of the segment and the anatomical considerations necessary to understand its relationship with other renal structures. We explore the physiopathological changes in thick ascending limbs occurring in both genetic and induced animal models of hypertension. We then discuss the racial differences and genetic defects that affect blood pressure in humans through changes in thick ascending limb transport rates. Throughout the text, we scrutinize methodologies and discuss the limitations of research techniques that, when overlooked, can lead investigators to make erroneous conclusions. Thus, in addition to advancing an understanding of the basic mechanisms of physiology, the ultimate goal of this work is to understand our research tools, to make better use of them, and to contextualize research data. Future advances in renal hypertension research will require not only collection of new experimental data, but also integration of our current knowledge.

Abstract
Hypertension was thought to be more important cardiovascular risk factor in men than in women. However, studies showed that overall incidence of hypertension-related cardiovascular diseases is higher in women comparing with men and this is particularly valid in menopause when prevalence of hypertension and its complications sharply and suddenly rises. It was also noticed that the effect of various antihypertensive groups was different in women and men. Some medications are prescribed more often in women, but it does not necessary mean that these drugs are more effective in this gender. There are several important reasons that could explain gender-induced differences in blood pressure levels, blood pressure control and antihypertensive treatment. They involve sex hormones, the renin-angiotensin-aldosterone and sympathetic nervous system, and arterial stiffness. However, taking into account many observational studies and trials, there are no consistent data regarding the impact of gender on effect of antihypertensive medications. Longitudinal study focused on gender and current antihypertensive groups would significantly help to understand the impact of gender. This might change therapeutic approach and improve cost-effectiveness in antihypertensive therapy in both genders. A full understanding of the pathophysiological characteristics of variations between genders demands additional research. This review article summarized the current knowledge regarding differences in the prevalence and awareness of arterial hypertension in women and men; alterations in pathophysiological mechanisms of hypertension between sexes; as well as the impact of sex on the effects of main antihypertensive groups of medications.
