ACE I/D Polymorphism, Plasma ACE Levels, and Long-term Kidney Outcomes or All-Cause Death in Patients With Type 1 Diabetes. Diabetes Care 2021; 44:1377-1384. [PMID: 33827803 PMCID: PMC8247517 DOI: 10.2337/dc20-3036] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/15/2020] [Accepted: 02/22/2021] [Indexed: 02/03/2023]
Abstract
OBJECTIVE The deletion (D) allele of the ACE insertion/deletion (I/D) polymorphism is a risk factor for diabetic kidney disease. We assessed its contribution to long-term kidney outcomes and all-cause death in patients with long-standing type 1 diabetes. RESEARCH DESIGN AND METHODS A total of 1,155 participants from three French and Belgian cohorts were monitored for a median duration of 14 (interquartile range 13) years. The primary outcome was the occurrence of end-stage kidney disease (ESKD) or a 40% drop in the estimated glomerular filtration rate (eGFR). Secondary outcomes were the individual components of the primary outcome, rapid decline in eGFR (steeper than -3 mL/min/1.73 m2 per year), incident albuminuria, all-cause death, and a composite ESKD or all-cause death. Hazard ratios (HRs) for XD versus II genotype and for baseline plasma ACE levels were computed by Cox analysis. Genotype performance in stratifying the primary outcome was tested. RESULTS Genotype distribution was 954 XD and 201 II. The primary outcome occurred in 20% of XD and 13% of II carriers: adjusted HR 2.07 (95% CI 1.32-3.40; P = 0.001). Significant associations were also observed for rapid decline in eGFR, incident albuminuria, ESKD, all-cause death, and ESKD or all-cause death. Baseline plasma ACE levels were higher in XD carriers and significantly associated with an increased risk of the primary outcome. The ACE genotype enhanced net reclassification improvement (0.154, 95% CI 0.007-0.279; P = 0.04) and integrated discrimination improvement (0.012, 95%CI 0.001-0.021; P = 0.02) for primary outcome stratification. CONCLUSIONS The D-allele of the ACE I/D polymorphism was associated with an increased risk of major kidney events and all-cause death in patients with long-standing type 1 diabetes.

Abstract
BACKGROUND AND PURPOSE Diabetic patients are at an increased risk of cardiovascular disease, in part due to inflammation and oxidative stress. These two pathological mechanisms also affect other organs and cells including the kidneys and progenitor cells. Angiotensin-(1-7) [Ang-(1-7)] has previously been shown to counterbalance pathological effects of angiotensin II, including inflammation and oxidative stress. The aim of this study was to investigate the effects of short-term (2 weeks) Ang-(1-7) treatment on cardiovascular and renal function in a mouse model of type 2 diabetes (db/db). EXPERIMENTAL APPROACH Eight- to nine-week-old db/db mice were administered either vehicle, Ang-(1-7) alone, or Ang-(1-7) combined with an inhibitor (losartan, PD123319, A-779, L-NAME or icatibant) daily for 14 days. KEY RESULTS An improvement in physiological heart function was observed in Ang-(1-7)-treated mice. Ang-(1-7) also reduced cardiomyocyte hypertrophy, fibrosis and inflammatory cell infiltration of the heart tissue and increased blood vessel number. These changes were blocked by antagonists of the MAS1, AT2 and bradykinin receptors and inhibition of NO formation. Treatment with Ang-(1-7) reduced glomerular damage and oxidative stress in kidney tissue. Bone marrow and circulating endothelial progenitors, as well as bone marrow mesenchymal stem cells, were increased in mice treated with Ang-(1-7). CONCLUSIONS AND IMPLICATIONS Short-term Ang-(1-7) treatment of young db/db mice improved heart function and reduced kidney damage. Treatment also improved bone marrow and circulating levels of endothelial and mesenchymal stem cells. All of this may contribute to improved cardiovascular and renal function.

Abstract
CONTEXT Angiotensin converting enzyme (ACE) gene encodes ACE, a key component of renin angiotensin system (RAS), plays an important role in blood pressure homeostasis by generating the vasoconstrictor peptide angiotensin II. EVIDENCE ACQUISITIONS Directory of Open Access Journals (DOAJ), Google Scholar, Pubmed (NLM), LISTA (EBSCO) and Web of Science have been searched. RESULTS The presence of ACE insertion/deletion (I/D) polymorphism affects the plasma level of ACE. ACE DD genotype is associated with the highest systemic and renal ACE levels compared with the lowest ACE activity in carriers of II genotype. CONCLUSIONS In this review focus has been performed on the study of ACE I/D polymorphism in various populations and its influence on the risk of onset and progression of diabetic nephropathy. Also, association between ACE I/D polymorphism and response to ACE inhibitor and angiotensin II receptor antagonists will be reviewed. Further, synergistic effect of this polymorphism and variants of some genes on the risk of development of diabetic nephropathy will be discussed.

Abstract
INTRODUCTION Our study was aimed at determining whether the polymorphism of genes for different components of the renin-angiotensin-aldosterone system could influence the renal hemodynamic response to losartan treatment. MATERIAL AND METHOD The study included 35 patients with type I diabetes mellitus and persistent albuminuria, genotyped for the 1166 A/C polymorphism gene for the angiotensin II type 1 receptor and I/D polymorphism of the angiotensin-converting enzyme gene. The participants were divided into groups according to the combinations of A or C allele: AA, AC, CC; and according to the combinations of I or D allele: II, ID and DD genotype. The patients received losartan therapy for 12 weeks. The renal hemodynamic measurements were determined at baseline and after the examination period. RESULTS Losartan therapy significantly reduced the filtration fraction from the baseline by 0.018 +/- 0.024 (p = 0.012) only in the AC genotype. The glomerular filtration rate remained unchanged in all genotype groups. A significant increase in the effective renal plasma flow was obtained only in AC genotype (544 +/- 88 vs 575 +/- 90 ml/min; p = 0.02), while significant reductions in the renal vascular resistance were found in AA group (115 +/- 25 vs 95 +/- 21 mmHg x l(-1) x min(-1), p = 0.001) and in AC group (118 +/- 30 vs 101 +/- 28 mmHg x l(-1) x min(-1); p = 0.001). A significant reduction of the glomerular filtration rate by 8 +/- 10 ml/min was obtained only in the DD genotype (p = 0.016), and only the DD genotype achieved a significant reduction of the filtration fraction by 0.019 +/- 0,022 (p = 0.008). The most pronounced increase of the effective renal plasma flow was found only in the ID genotype (536 +/- 75 vs 591 +/- 63 ml/min; p = 0.01). The reduction of the renal vascular resistance was independent of ACE gene polymorphism. CONCLUSION Our study shows that individual renal vascular response to losartan treatment in diabetic patients with persistent albuminuria, could be influenced by genetic polymorphisms.

Abstract
IMPORTANCE OF THE FIELD Only 23 - 41% of hypertensive patients receiving antihypertensive drugs achieve adequate blood pressure control. Multiple physiological systems regulate blood pressure and variation in genes involved in these systems may account for enhanced or diminished blood pressure lowering response to antihypertensive therapy. AREAS COVERED IN THIS REVIEW We explored explanations for variation in blood pressure response to antihypertensive drugs by linking genetic polymorphisms in renin-angiotensin-aldosterone system (RAAS) genes to antihypertensive drug response on intermediate parameters (e.g., potassium excretion, aldosterone levels). A MEDLINE search (1966 - 2008) was performed to identify publications reporting effects of genetic polymorphisms in the RAAS on antihypertensive drug response with regard to intermediate parameters. WHAT THE READER WILL GAIN With regard to the ACE insertion/deletion and the angiotensinogen -217G/A polymorphism variation in blood pressure response could be explained by effects on intermediate parameters. However, most studies that were identified with our search varied in study design, population and outcome, which complicate adequate comparisons. TAKE HOME MESSAGE Little evidence is available that explains these pharmacogenetic interactions. In the future, a better understanding of these mechanisms should provide a more solid evidence base for the individualized hypertension treatment based on genetic variation.

Abstract
The idea of individualizing therapies to obtain optimal clinical results is not new but has only recently been applied to kidney diseases. Nonetheless, kidney disorders present a variety of opportunities to personalize medicine. Here, the heterogeneity of kidney disorders is reviewed to provide a rationale for pursuing personalized medicine. Data on adjusting therapy on the basis of pharmacogenetics/genomics and pharmacodynamics are summarized to demonstrate where the field is, and biomarker studies that reflect the future of personalized medicine are discussed. The goal of this review is to demonstrate that we can personalize therapy for kidney diseases but that considerable investment in new research will be required for personalized medicine to be routinely used in nephrology clinics.

Abstract
Introduction.The aim of this study was to document the impact of renin-angiotensin system (RAS) polymorphisms on renal haemodynamics and renal hormones in type 2 diabetes mellitus. Materials and methods. Fifty-nine adult patients were studied. Renal haemodynamics were evaluated using 99mTc-MAG3 clearance (MAG3 Cle) using Bubeck's method and captopril renogram. RAS hormones and angiotensin-converting enzyme (ACE) levels were measured before and after captopril.ACE, angiotensin II type 1 receptor and angiotensinogen gene polymorphisms were analysed. Results. Post-captopril MAG3Cle values were significantly lower in patients with microalbuminuria compared to nonproteinuric patients. Statistically significant negative correlation was found between clearance percentage change values and HbA1c levels (r: —0.42, p=0.009). MAG3Cle was relatively lower following captopril administration in DD patients, while a relative increment was observed in I allele carriers (p=0.02).TheAC-CC group had significantly higher mean post-captopril clearance value compared to the AA genotype (480.9±56.1 ml/min/1.73 m2 vs. 428.4±74.8 ml/min/1.73 m2, p=0.022). Conclusions. Our data indicate that the heterogeneity of patients' response to ACE inhibition is, at least partly, genetically determined, and the genetic polymorphisms in RAS might predict the acute responsiveness to ACE inhibitors.

Abstract
The angiotensin converting enzyme (ACE) is a component of the renin–angiotensin–aldosterone system (RAAS). The RAAS – involved primarily in blood pressure and sodium homeostasis – is activated in many renal and cardiovascular diseases, and therapy with ACE inhibitors and other blockers of the RAAS has proven to be clinically beneficial. Plasma and tissue levels of ACE are at least partially determined by a genetic polymorphism based on the presence (insertion [I]) or absence (deletion [D]) of a 287 base pair element in intron 16. In particular Asian subjects with the DD genotype (and increased ACE activity) have been reported to be at higher risk for cardiovascular disorders and nephropathy. Numerous studies evaluated the role of the ACE I/D polymorphism as well as other genetic variants of the RAAS in the context of RAAS inhibitor therapy. However, as race and environmental factors, such as salt intake also affect treatment response most studies were underpowered leading to conflicting results.

Abstract
Despite the huge amount of studies looking for candidate genes, the ACE gene remains the unique, well-characterized locus clearly associated with pathogenesis and progression of chronic kidney disease, and with response to treatment with drugs that directly interfere with the renin angiotensin system (RAS), such as angiotensin converting enzyme (ACE) inhibitors and angiotensin II receptor antagonists (ARA). The II genotype is protective against development and progression of type I and type II nephropathy and is associated with a slower progression of nondiabetic proteinuric kidney disease. ACE inhibitors are particularly effective at the stage of normoalbuminuria or microalbuminuria in both type I and type II diabetics with the II genotype, whereas the DD genotype is associated with a better response to ARA therapy in overt nephropathy of type II diabetes and to ACE inhibitors in male patients with nondiabetic proteinuric nephropathies. The role of other RAS or non-RAS polymorphisms and their possible interactions with different ACE I/D genotypes are less clearly defined. Thus, evaluating the ACE I/D polymorphism is a reliable tool to identify patients at risk and those who may benefit the most of renoprotective therapy with ACE inhibitors or ARA. This may guide pharmacologic therapy in individual patients and help design clinical trials in progressive nephropathies. Moreover, it might help optimize prevention and intervention strategies at population levels, in particular, in countries where resources are extremely limited and 1 million patients continue to die every year of cardiovascular or renal disease.

Abstract
The aim of this study was to test the hypothesis that treatment with angiotensin-(1-7) [ANG-(1-7)] or ANG-(1-7) nonpeptide analog AVE-0991 can produce protection against diabetes-induced cardiovascular dysfunction. We examined the influence of chronic treatment (4 wk) with ANG-(1-7) (576 microg.kg(-1).day(-1) ip) or AVE-0991 (576 microg.kg(-1).day(-1) ip) on proteinuria, vascular responsiveness of isolated carotid and renal artery ring segments and mesenteric bed to vasoactive agonists, and cardiac recovery from ischemia-reperfusion in streptozotocin-treated rats (diabetes). Animals were killed 4 wk after induction of diabetes and/or treatment with ANG-(1-7) or AVE-0991. There was a significant increase in urine protein (231 +/- 2 mg/24 h) in diabetic animals compared with controls (88 +/- 6 mg/24 h). Treatment of diabetic animals with ANG-(1-7) or AVE-0991 resulted in a significant reduction in urine protein compared with vehicle-treated diabetic animals (183 +/- 16 and 149 +/- 15 mg/24 h, respectively). Treatment with ANG-(1-7) or AVE-0991 also prevented the diabetes-induced abnormal vascular responsiveness to norepinephrine, endothelin-1, angiotensin II, carbachol, and histamine in the perfused mesenteric bed and isolated carotid and renal arteries. In isolated perfused hearts, recovery of left ventricular function from 40 min of global ischemia was significantly better in ANG-(1-7)- or AVE-0991-treated animals. These results suggest that activation of ANG-(1-7)-mediated signal transduction could be an important therapeutic strategy to reduce cardiovascular events in diabetic patients.

Abstract
Angiotensin (Ang)-converting enzyme (ACE) inhibitors are widely used for the treatment of cardiovascular diseases. Not all patients respond to ACE inhibitors, and it has been suggested that genetic variation might be a useful marker to predict the therapeutic efficacy of these drugs. In particular, the ACE insertion (I)/deletion (D) polymorphism has been investigated in this regard. Despite a decade of intensive research involving the genotyping of thousands of patients, we still do not know whether ACE genotyping helps in predicting the success of ACE inhibition. This review critically addresses the concept that predictive information on therapeutic efficacy of ACE inhibitors might be obtained based on ACE genotyping. It answers the following questions: Do higher ACE levels really result in higher Ang II levels? Is ACE the only converting enzyme in humans? Does ACE inhibition affect ACE expression? Why does ACE have 2 catalytically active domains? What is the relevance of ACE inhibitor-induced signaling through membrane-bound ACE? The review ends with the proposal that ACE phenotyping may prove to be a better first step toward personalized medicine for ACE inhibitors than ACE genotyping.
