Abstract
BACKGROUND Guidelines suggest that adults with diabetes and kidney disease receive treatment with angiotensin-converting-enzyme inhibitors (ACEi) or angiotensin receptor blockers (ARB). This is an update of a Cochrane review published in 2006. OBJECTIVES We compared the efficacy and safety of ACEi and ARB therapy (either as monotherapy or in combination) on cardiovascular and kidney outcomes in adults with diabetes and kidney disease. SEARCH METHODS We searched the Cochrane Kidney and Transplants Register of Studies to 17 March 2024 through contact with the Information Specialist using search terms relevant to this review. Studies in the Register are identified through searches of CENTRAL, MEDLINE, and EMBASE, conference proceedings, the International Clinical Trials Registry Platform (ICTRP) Search Portal, and ClinicalTrials.gov. SELECTION CRITERIA We included studies evaluating ACEi or ARB alone or in combination, compared to each other, placebo or no treatment in people with diabetes and kidney disease. DATA COLLECTION AND ANALYSIS Two authors independently assessed the risk of bias and extracted data. Summary estimates of effect were obtained using a random-effects model, and results were expressed as risk ratios (RR) and their 95% confidence intervals (CI) for dichotomous outcomes and mean difference (MD) or standardised mean difference (SMD) and 95% CI for continuous outcomes. Confidence in the evidence was assessed using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach. MAIN RESULTS One hundred and nine studies (28,341 randomised participants) were eligible for inclusion. Overall, the risk of bias was high. Compared to placebo or no treatment, ACEi may make little or no difference to all-cause death (24 studies, 7413 participants: RR 0.91, 95% CI 0.73 to 1.15; I2 = 23%; low certainty) and with similar withdrawals from treatment (7 studies, 5306 participants: RR 1.03, 95% CI 0.90 to 1.19; I2 = 0%; low certainty). ACEi may prevent kidney failure (8 studies, 6643 participants: RR 0.61, 95% CI 0.39 to 0.94; I2 = 0%; low certainty). Compared to placebo or no treatment, ARB may make little or no difference to all-cause death (11 studies, 4260 participants: RR 0.99, 95% CI 0.85 to 1.16; I2 = 0%; low certainty). ARB have uncertain effects on withdrawal from treatment (3 studies, 721 participants: RR 0.85, 95% CI 0.58 to 1.26; I2 = 2%; low certainty) and cardiovascular death (6 studies, 878 participants: RR 3.36, 95% CI 0.93 to 12.07; low certainty). ARB may prevent kidney failure (3 studies, 3227 participants: RR 0.82, 95% CI 0.72 to 0.94; I2 = 0%; low certainty), doubling of serum creatinine (SCr) (4 studies, 3280 participants: RR 0.84, 95% CI 0.72 to 0.97; I2 = 32%; low certainty), and the progression from microalbuminuria to macroalbuminuria (5 studies, 815 participants: RR 0.44, 95% CI 0.23 to 0.85; I2 = 74%; low certainty). Compared to ACEi, ARB had uncertain effects on all-cause death (15 studies, 1739 participants: RR 1.13, 95% CI 0.68 to 1.88; I2 = 0%; low certainty), withdrawal from treatment (6 studies, 612 participants: RR 0.91, 95% CI 0.65 to 1.28; I2 = 0%; low certainty), cardiovascular death (13 studies, 1606 participants: RR 1.15, 95% CI 0.45 to 2.98; I2 = 0%; low certainty), kidney failure (3 studies, 837 participants: RR 0.56, 95% CI 0.29 to 1.07; I2 = 0%; low certainty), and doubling of SCr (2 studies, 767 participants: RR 0.88, 95% CI 0.52 to 1.48; I2 = 0%; low certainty). Compared to ACEi plus ARB, ACEi alone has uncertain effects on all-cause death (6 studies, 1166 participants: RR 1.08, 95% CI 0.49 to 2.40; I2 = 20%; low certainty), withdrawal from treatment (2 studies, 172 participants: RR 0.78, 95% CI 0.33 to 1.86; I2 = 0%; low certainty), cardiovascular death (4 studies, 994 participants: RR 3.02, 95% CI 0.61 to 14.85; low certainty), kidney failure (3 studies, 880 participants: RR 1.36, 95% CI 0.79 to 2.32; I2 = 0%; low certainty), and doubling of SCr (2 studies, 813 participants: RR 1.14, 95% CI 0.70 to 1.85; I2 = 0%; low certainty). Compared to ACEi plus ARB, ARB alone has uncertain effects on all-cause death (7 studies, 2607 participants: RR 1.02, 95% CI 0.76 to 1.37; I2 = 0%; low certainty), withdrawn from treatment (3 studies, 1615 participants: RR 0.81, 95% CI 0.53 to 1.24; I2 = 0%; low certainty), cardiovascular death (4 studies, 992 participants: RR 3.03, 95% CI 0.62 to 14.93; low certainty), kidney failure (4 studies, 2321 participants: RR 1.15, 95% CI 0.67 to 1.95; I2 = 29%; low certainty), and doubling of SCr (3 studies, 2252 participants: RR 1.18, 95% CI 0.85 to 1.64; I2 = 0%; low certainty). Comparative effects of different ACEi or ARB and low-dose versus high-dose ARB were rarely evaluated. No study compared different doses of ACEi. Adverse events of ACEi and ARB were rarely reported. AUTHORS' CONCLUSIONS ACEi or ARB may make little or no difference to all-cause and cardiovascular death compared to placebo or no treatment in people with diabetes and kidney disease but may prevent kidney failure. ARB may prevent the doubling of SCr and the progression from microalbuminuria to macroalbuminuria compared with a placebo or no treatment. Despite the international guidelines suggesting not combining ACEi and ARB treatment, the effects of ACEi or ARB monotherapy compared to dual therapy have not been adequately assessed. The limited data availability and the low quality of the included studies prevented the assessment of the benefits and harms of ACEi or ARB in people with diabetes and kidney disease. Low and very low certainty evidence indicates that it is possible that further studies might provide different results.

Abstract
With the increasing prevalence of diabetes mellitus (DM) and diabetic nephropathy (DN), effective treatment is particularly important for the recovery of patients. However, the currently approved drugs are usually tailored to clinical symptoms and no mechanism-targeted drugs are available. In this study, the combination of metabolomics and network pharmacology was applied to provide reasonable medication combination regimens to meet the different clinical needs for the targeted treatment of DM and DN. An NMR-based metabolomic strategy was applied to identify the potential urinary biomarkers of DM or/and DN, while network pharmacology was used to identify the therapy targets of DM and DN by intersecting the targets of diseases and currently approved drugs. According to the enriched signaling pathways using the potential biomarkers and the therapy targets, the specific medication combinations were recommended for the specific clinical demands in terms of hypoglycemic, hypertensive, and/or lipid-lowering. For DM, 17 potential urinary biomarkers and 12 disease-related signaling pathways were identified, and 34 combined medication regimens related to hypoglycemia, hypoglycemia, and hypertension, and hypoglycemia, hypertension, and lipid-lowering were administered. For DN, 22 potential urinary biomarkers and 12 disease-related signaling pathways were identified, and 21 combined medication regimens related to hypoglycemia, hypoglycemia, and hypertension were proposed. Molecular docking was used to verify the binding ability, docking sites, and structure of the drug molecules to target proteins. Moreover, an integrated biological information network of the drug-target-metabolite-signaling pathways was constructed to provide insights into the underlined mechanism of DM and DN as well as clinical combination therapy.

Abstract
AIMS To assess the effectiveness of renin-angiotensin-aldosterone system (RAAS) inhibitors, angiotensin-converting enzyme inhibitors (ACEIs) and angiotensin II receptor blockers (ARBs) separately to prevent all-cause mortality, myocardial infarction (MI), stroke and heart failure (HF) in patients with diabetes considering the number needed to treat (NNT) and minimal clinical effect (MCE). METHODS Data from 17 morbidity-mortality trials in patients with diabetes were used to calculate NNTs and evaluate MCE to prevent all-cause mortality, myocardial infarction, stroke, and heart failure. RESULTS A total of 17 trials involving 42,037 patients were included in this meta-analysis. Mean follow-up was 3.7 years. ACEIs significantly reduced the risk of all-cause mortality, MI and HF; the corresponding mean NNTBs were 48, 62 and 78, respectively, but ARBs were only associated with a reduction in heart failure. The clinical significance assessment of the included trials indicated that most of the statistically significant trial results had no definitive clinical significance, and only some of them had possible clinical significance. CONCLUSIONS Among patients with diabetes, ACEIs reduced all-cause mortality, MI and HF, whereas ARBs could only prevent HF. However, none of the results of these trials had clear clinical significance, and most had only possible clinical significance.

Abstract
One of the central aims in randomized clinical trials is to find well-validated surrogate endpoints to reduce the sample size and/or duration of trials. Clinical researchers and practitioners have proposed various surrogacy measures for assessing candidate surrogate endpoints. However, most existing surrogacy measures have the following shortcomings: (i) they often fall outside the range [0,1], (ii) they are imprecisely estimated, and (iii) they ignore the interaction associations between a treatment and candidate surrogate endpoints in the evaluation of the surrogacy level. To overcome these difficulties, we propose a new surrogacy measure, the proportion of treatment effect mediated by candidate surrogate endpoints (PMS), based on the decomposition of the treatment effect into direct, indirect, and interaction associations mediated by candidate surrogate endpoints. In addition, we validate the advantages of PMS through Monte Carlo simulations and the application to empirical data from ORIENT (the Olmesartan Reducing Incidence of Endstage Renal Disease in Diabetic Nephropathy Trial).

Abstract
AIM To assess the impact of angiotensin-converting enzyme inhibitors and angiotensin receptor blockers on renal and mortality outcomes in people with Type 2 diabetes and proteinuria. METHODS A literature search up to 6 June 2019 was performed. We included randomized trials of ≥100 participants with Type 2 diabetes and micro- or macroalbuminuria comparing an angiotensin-converting enzyme inhibitor or angiotensin receptor blocker with placebo ± background anti-hypertensives or non-angiotensin-converting enzyme inhibitor or angiotensin receptor blocker-containing anti-hypertensives, which included follow-up of ≥12 months. Endpoints included doubling of serum creatinine, end-stage renal disease, all-cause and cardiovascular mortality and progression and regression of proteinuria. A Hartung-Knapp random-effects model (between-study variance calculated using the Paule-Mandel estimator) producing a risk ratio with 95% confidence interval was employed. RESULTS The use of an angiotensin-converting enzyme inhibitor or angiotensin receptor blocker was not associated with a significant reduction in the risk of a doubling in serum creatinine (n = 7 trials, RR = 0.77, 95% CI = 0.50-1.21). Angiotensin-converting enzyme inhibitors or angiotensin receptor blockers reduced the risk of progressing to end-stage renal disease (n = 8, RR = 0.79, 95% CI = 0.75-0.83). No difference in all-cause (n = 11, RR = 0.98, 95% CI = 0.89-1.08) or cardiovascular mortality (n = 6 trials, RR = 1.08, 95% CI = 0.92-1.28), nor the composite outcome of doubling in serum creatinine, end-stage renal disease or mortality (n = 3 trials, RR = 0.87, 95% CI = 0.72-1.06), was observed. Progression of proteinuria was decreased with angiotensin-converting enzyme inhibitor or angiotensin receptor blocker use vs. control (n = 10, RR = 0.49, 95% CI = 0.33-0.74). Regression of proteinuria was not improved with an angiotensin-converting enzyme inhibitor or angiotensin receptor blocker (n = 11, RR = 1.55, 95% CI = 0.93-2.58). CONCLUSION Angiotensin-converting enzyme inhibitors and angiotensin receptor blockers may reduce the risk of end-stage renal disease and slow the progression of nephropathy, but they do not appear to decrease all-cause or cardiovascular mortality in people with Type 2 diabetes and proteinuria.

Abstract
In patients with type 2 diabetes (T2D), microvascular changes in the kidney often result in diabetic kidney disease (DKD), the progression of which is associated with an increased risk of cardiovascular (CV) and all-cause mortality. Sodium-glucose cotransporter-2 inhibitors (SGLT-2is) are a newer class of oral glucose-lowering therapies that were associated with significant reductions in the risk of major adverse CV events, CV death, and hospitalization for heart failure compared with placebo in CV outcomes trials (CVOTs) of patients with T2D and established CV disease or varying levels of CV risk. In addition, SGLT-2is reduced the risks of clinically relevant renal outcomes in these large randomized studies, indicating the potential for renoprotective effects in patients with T2D and DKD. This review discussed the non-glycemic effects of SGLT-2is in patients with T2D and renal impairment, including reductions in systolic and diastolic blood pressure, decreases in albuminuria and plasma uric acid, changes in estimated glomerular filtration rate, and minimal changes in electrolytes. Potential mechanisms for the renoprotective effects of SGLT-2is observed in CVOTs were considered, including the likely incremental benefits of SGLT-2is when added to renin-aldosterone-angiotensin system inhibitors (RAASis). The possibility of extending the use of SGLT-2is to patients with non-DKD was also discussed. Although the exact mechanisms by which SGLT-2is improve renal outcomes are not fully understood, they are likely to be multifactorial and additive when these drugs are used in combination with RAASis in patients with DKD.

Abstract
INTRODUCTION Current guidelines recommend renin-angiotensin-aldosterone system (RAAS) inhibitors in the treatment of diabetic kidney disease (DKD). However, evidence suggests that the combined use of RAAS blockers may be associated with increased rates of adverse events. OBJECTIVES Our objective was to examine the efficacy and safety of dual blockade of the RAAS in patients with DKD. METHODS This was a systematic review and meta-analysis of randomized controlled trials (RCTs) published between January 1990 and January 2018 sourced via the PubMed, EMBASE, and Cochrane Library databases. RCTs were included if they investigated the efficacy and safety of dual blockade therapy compared with monotherapy in patients with DKD. Random effects models were used in meta-analysis to account for heterogeneities in effect sizes across the reviewed studies. Analyses were stratified by blood pressure and albuminuria. We further conducted subgroup analyses by considering various combinations of RAAS inhibitors. RESULTS Based on 42 RCTs with 14,576 patients, dual RAAS blockade therapy was associated with significant decreases in blood pressure, albuminuria, and proteinuria. However, dual therapy was not superior to monotherapy in terms of reductions in all-cause mortality, cardiovascular mortality, or progression to end-stage renal disease (ESRD). Significant increases in serum potassium and rates of hyperkalemia and hypotension were more common in patients treated with dual therapy. However, glomerular filtration rates (GFR) did not decrease significantly with dual therapy. In subgroup analysis, an angiotensin-converting enzyme inhibitor (ACEI) plus an angiotensin-receptor blocker (ARB) or a direct renin inhibitor (DRI) plus an ACEI/ARB did not significantly increase the risk of hyperkalemia, hypotension, and adverse events, and the risk of hypotension increased significantly within the normotensive subgroup but not within the hypertensive subgroup. The risk of hyperkalemia increased significantly in patients with DKD with macroalbuminuria but not in those with microalbuminuria. CONCLUSION Dual inhibition therapy is superior to monotherapy for blood pressure control and urine protein reduction, though such superiority does not translate into improvements in longer-term outcomes, such as reduced progression to ESRD, all-cause mortality, and cardiovascular mortality. An ACEI plus an ARB or a DRI plus an ACEI/ARB may be a safe and effective therapy for patients with DKD, and combination therapy may be suitable for patients with DKD and hypertension and microalbuminuria.

Abstract
This study sought to assess the prognostic impact of treatment with angiotensin-converting enzyme inhibitors (ACEi) or angiotensin receptor blockers (ARB) on recurrences of ventricular tachyarrhythmias in recipients of implantable cardioverter-defibrillators (ICD). Using a large retrospective registry including consecutive ICD recipients with documented episodes of ventricular tachycardia (VT) or fibrillation (VF) from 2002 to 2016, those patients treated with ACEi/ARB were compared with patients without. The primary prognostic endpoint was the first recurrence of ventricular tachyarrhythmias and related ICD therapies at 5 years. Multivariable Cox regression analyses were applied within the entire cohort, and thereafter, Kaplan-Meier analyses were performed in propensity-matched subgroups. A total of 592 consecutive ICD recipients were included (81% treated with ACEi/ARB and 19% without). Although ACEi/ARB was associated with no differences in overall recurrence of ventricular tachyarrhythmias, ACEi/ARB was associated with improved freedom from appropriate ICD therapy within multivariable Cox regressions (hazard ratio = 0.666; P = 0.043), especially in patients with index episodes of VF, left ventricular ejection fraction <35%, coronary artery disease, secondary preventive ICD, and glomerular filtration rate <45 mL/min/1.73 m. In the propensity-matched subgroup, ACEi/ARB still prolonged freedom from appropriate ICD therapies (hazard ratio = 0.380; 95% confidence interval 0.193-0.747; P = 0.005). In conclusion, ACEi/ARB therapy was associated with improved freedom from appropriate ICD therapies.

Objective: To examine the efficacy and safety of dual blockade of the renin-angiotensin-aldosterone system (RAAS) among patients with type 2 diabetic kidney disease. Data Sources: We searched the major literature repositories, including the Cochrane Central Register of Controlled Trials, MEDLINE and EMBASE, for randomized clinical trials published between January 1990 and October 2015 that compared the efficacy and safety of the use of dual blockade of the RAAS versus the use of monotherapy, without applying any language restrictions. Keywords for the searches included “diabetic nephropathy,” “chronic kidney disease,” “chronic renal insufficiency,” “diabetes mellitus,” “dual therapy,” “combined therapy,” “dual blockade,” “renin-angiotensin system,” “angiotensin-converting enzyme inhibitor,” “angiotensin-receptor blocker,” “aldosterone blockade,” “selective aldosterone blockade,” “renin inhibitor,” “direct renin inhibitor,” “mineralocorticoid receptor blocker,” etc. Study Selection: The selected articles were carefully reviewed. We excluded randomized clinical trials in which the kidney damage of patients was related to diseases other than diabetes mellitus. Results: Combination treatment with an angiotensin-converting enzyme inhibitor supplemented by an angiotensin II receptor blocking agent is expected to provide a more complete blockade of the RAAS and a better control of hypertension. However, existing literature has presented mixed results, in particular, related to patient safety. In view of this, we conducted a comprehensive literature review in order to explain the rationale for dual blockade of the RAAS, and to discuss the pros and cons. Conclusions: Despite the negative results of some recent large-scale studies, it may be immature to declare that the dual blockade is a failure because of the complex nature of the RAAS surrounding its diversified functions and utility. Further trials are warranted to study the combination therapy as an evidence-based practice.

Abstract
This study investigated the effects of combined minimal concentrations of quercetin and pioglitazone on angiotensin II-induced contraction of the aorta from fructose-streptozotocin (F-STZ)-induced type 2 diabetic rats and the possible role of superoxide anions (O2(-)) and nitric oxide (NO) in their potential therapeutic interaction. Contractile responses to Ang II of aortic rings from Sprague-Dawley (SD) and F-STZ rats were tested following pre-incubation of the tissues in the vehicle (DMSO; 0.05%), quercetin (Q, 0.1 μM), pioglitazone (P, 0.1 μM) or their combination (P + Q; 0.1 μM each). The amount of superoxide anion was evaluated by lucigenin-enhanced chemiluminescence and dihydroethidium fluorescence, and NO by assay of total nitrate/nitrite, and 4-Amino-5-Methylamino-2',7'-Difluorofluorescein (DAF-FM) diacetate. The synergistic reduction of Ang II-induced contraction of diabetic but not normal aorta with minimally effective concentrations of P + Q occurs through inhibiting O2(-) and increasing NO bioavailability. This finding opens the possibility of maximal vascular protective/antidiabetic effects with low dose pioglitazone combined with quercetin, thus minimizing the risk of adverse effects.

Abstract
Diabetic Kidney Disease (DKD) is the leading cause of chronic kidney disease in developed countries and its prevalence has increased dramatically in the past few decades. These patients are at an increased risk for premature death, cardiovascular disease, and other severe illnesses that result in frequent hospitalizations and increased health-care utilization. Although much progress has been made in slowing the progression of diabetic nephropathy, renal dysfunction and the development of end-stage renal disease remain major concerns in diabetes. Dysregulation of the renin-angiotensin-aldosterone system (RAAS) results in progressive renal damage. RAAS blockade is the cornerstone of treatment of DKD, with proven efficacy in many arenas. The theoretically-attractive option of combining these medications that target different points in the pathway, potentially offering a more complete RAAS blockade, has also been tested in clinical trials, but long-term outcomes were disappointing. This review examines the “state of play” for RAAS blockade in DKD, dual blockade of various combinations, and a perspective on its benefits and potential risks.

Abstract
Single renin-angiotensin-aldosterone system (RAAS) blockade has been shown to be effective and safe for the treatment of hypertension, coronary heart disease (CHD), heart failure (HF), diabetes, and chronic kidney disease (CKD) with proteinuria. Due to the action of RAAS blockers at various levels of the RAAS cascade, it was hypothesized that dual RAAS blockade would result in more complete inhibition of angiotensin II (Ang II) production and be more effective in blocking its detrimental cardiovascular remodeling effects. Unfortunately, several clinical trials in patients with hypertension, CHD, HF, and CKD with proteinuria have demonstrated no superiority of dual versus single RAAS blockade, but a higher incidence of adverse events. Based on these findings, dual RAAS blockade is no longer recommended for the routine treatment of various cardiovascular diseases, except diabetic nephropathy with proteinuria and HF with reduced ejection fraction. All the new information gathered from studies within the last 3 years will be presented in this review.

Abstract
BACKGROUND Diabetic nephropathy (DN), especially type 2 diabetes, is now increasing rapidly worldwide, also in Asian countries, and is one of the major long-term vascular complications. The pathogenesis of DN involves both genetic and environmental factors. Around 30-40% of type 2 diabetic patients develop DN despite strict blood glucose and/or blood pressure control. Although it is considered that the genetic background may influence the initiation and progression of DN, the candidate genes are still obscure. SUMMARY To search for genes that are involved in the susceptibility of DN, a candidate gene approach was taken in the beginning before the development of genome-wide association studies. Although a candidate gene approach can detect rare genetic variants, in advance we need known or presumed pathophysiological knowledge of the specific gene. Investigations using spontaneous animal models are important to determine the pathogenesis and treatment of DN patients. There are many spontaneous animal models, such as the NOD and Akita mice for type 1 diabetes and the Ob/Ob, db/db, Tsumura Suzuki Obese Diabetics, and KK-A (y) mice for type 2 diabetes. Furthermore, the toxicity of persistent hyperglycemia, the activation of reactive oxygen species, systemic and/or glomerular hypertension, microinflammation, dyslipidemia, and other factors are considered to play important roles. Diabetic patients with normoalbuminuria and normal renal function showed typical histological patterns of DN. The discovery of a specific and reliable diagnostic and prognostic biomarker other than albuminuria is urgently needed and indispensable. Since large clinical trials of oral hypoglycemic drugs in renal failure are lacking, these recommendations will need to be regularly updated after results of larger randomized trials with longer follow-up durations are available. KEY MESSAGE It is necessary to summarize the basic and clinical features of DN patients in Asia and to use these for the treatment of such patients. FACTS FROM EAST AND WEST The prevalence of DN is increasing in Asia and Western countries alike. The deletion (D) allele of the angiotensin-converting enzyme gene is associated with progression to end-stage renal disease in Asian patients with DN, but this association is uncertain in Europeans. An association between DN and polymorphism of the gene coding for acetyl coenzyme A carboxylase β has been reported in Asian and Western populations. Both in Japan and the US, criteria for diagnosis are a 5-year history of diabetes and persistent albuminuria. Renal biopsy should be done in patients with severe hematuria, cellular casts and - in the US - hepatitis and HIV to rule out other pathologies. Diabetic retinopathy is considered a key criterion in Japan, but the absence of it does not rule out DN in the US. Enlargement of the kidney is observed as a diagnostic criterion in Japan. The differential use of renal biopsy as diagnostic tool might account for a different prevalence between Asian countries. Some Japanese diabetic patients showed typical histological alterations for DN with a normal ACR and GFR. The clinical classification is similar between Japan and the US including five stages based on ACR and GFR. The Japanese guidelines do not include blood pressure values for the classification of DN. Guidelines for DN treatment are evolving quickly both in Asia and Western countries based on the numerous clinical trials performed worldwide. Targeting the angiotensin system for its hemodynamic and nonhemodynamic effects is a common approach. DPP-4 inhibitors are widely used in Japan and might have a higher glucose-lowering effect in Asian patients due to their specific diet. A randomized, double-blind placebo-controlled study has been launched to assess the efficacy of the Chinese herbal tea extract Shenyan Kangfu in DN.

Abstract
The aim of the study was to analyze the clinical use of different types of combination therapy in a large sample of consecutive patients with uncontrolled hypertension referred to Hypertension Centre. We performed a retrospective analysis of combination antihypertensive therapy in 1254 consecutive patients with uncontrolled hypertension receiving at least triple-combination antihypertensive therapy. Among the most prescribed antihypertensive classes were renin-angiotensin blockers (96.8%), calcium channel blockers (82.5%), diuretics (82.0%), beta-blockers (73.0%), centrally acting drugs (56.0%) and urapidil (24.1%). Least prescribed were spironolactone (22.2%) and alpha-1-blockers (17.1%). Thiazide/thiazide-like diuretics were underdosed in more than two-thirds of patients. Furosemide was prescribed in 14.3% of patients treated with diuretics, while only indicated in 3.9%. Inappropriate combination therapy was found in 40.4% of patients. Controversial dual and higher blockade of renin-angiotensin system occurred in 25.2%. Incorrect use of a combination of two antihypertensive drugs with the similar mechanism of action was found in 28.1%, most commonly a combination of two drugs with central mechanism (13.5%). In conclusion, use of controversial or incorrect combinations of drugs in uncontrolled hypertension is common. Diuretics are frequently underdosed and spironolactone remains neglected in general practice. The improper combination of antihypertensive drugs may contribute to uncontrolled hypertension.

The necessity and effectiveness of mineralocorticoid receptor antagonist in the treatment of diabetic nephropathy. Hypertens Res 2015; 38:367-74.

Abstract
Diabetes mellitus is a major cause of chronic kidney disease (CKD), and diabetic nephropathy is the most common primary disease necessitating dialysis treatment in the world including Japan. Major guidelines for treatment of hypertension in Japan, the United States and Europe recommend the use of angiotensin-converting enzyme inhibitors and angiotensin-receptor blockers, which suppress the renin-angiotensin system (RAS), as the antihypertensive drugs of first choice in patients with coexisting diabetes. However, even with the administration of RAS inhibitors, failure to achieve adequate anti-albuminuric, renoprotective effects and a reduction in cardiovascular events has also been reported. Inadequate blockade of aldosterone may be one of the reasons why long-term administration of RAS inhibitors may not be sufficiently effective in patients with diabetic nephropathy. This review focuses on treatment in diabetic nephropathy and discusses the significance of aldosterone blockade. In pre-nephropathy without overt nephropathy, a mineralocorticoid receptor antagonist can be used to enhance the blood pressure-lowering effects of RAS inhibitors, improve insulin resistance and prevent clinical progression of nephropathy. In CKD categories A2 and A3, the addition of a mineralocorticoid receptor antagonist to an RAS inhibitor can help to maintain 'long-term' antiproteinuric and anti-albuminuric effects. However, in category G3a and higher, sufficient attention must be paid to hyperkalemia. Mineralocorticoid receptor antagonists are not currently recommended as standard treatment in diabetic nephropathy. However, many studies have shown promise of better renoprotective effects if mineralocorticoid receptor antagonists are appropriately used.

Abstract
The renin-angiotensin-aldosterone system (RAAS) has a key role in the regulation of blood pressure, sodium and water balance, and cardiovascular and renal homeostasis. In diabetic nephropathy, excessive activation of the RAAS results in progressive renal damage. RAAS blockade using angiotensin-converting-enzyme inhibitors or angiotensin-receptor blockers is the cornerstone of treatment of diabetic renal disease. Alternative RAAS-blockade strategies include renin inhibition and aldosterone blockade. Data from small initial studies of these agents are promising. However, single-agent interventions do not fully block the RAAS and patients treated with these therapies remain at high residual renal risk. Approaches to optimize drug responses include dietary changes and increasing dosages. The theoretically attractive option of combining different RAAS interventions has also been tested in clinical trials but long-term outcomes were disappointing. However, dual RAAS blockade might represent a good therapeutic option for specific patients. A better knowledge of the pathophysiology of the RAAS is crucial to fully understand the mechanisms of action of RAAS blockers and to exploit their renoprotective effects. Moreover, lifestyle interventions or diagnostic tools might be used to optimize RAAS blockade and identify those patients who are most likely to benefit from the therapy.
