Adapting Clinical Practice Guidelines for Chronic Kidney Disease: Blood Pressure Management and Kidney Replacement Therapy in Adults and Children in the Saudi Arabian Context Using the Grading of Recommendations Assessment, Development, and Evaluation-ADOLOPMENT Methodology

This practice guideline was developed by the chronic kidney disease (CKD) Task Force, which was composed of clinical and methodological experts. The Saudi Arabian Ministry of Health and its health holding company commissioned this guideline project to support the realization of Vision 2030's health-care transformation pillar. The synthesis of these guidelines was guided by the Grading of Recommendations Assessment, Development, and Evaluation (GRADE)- ADOLOPMENT methodology. The final guidelines addressed 12 clinical questions on the management of blood pressure in patients with CKD through a set of recommen-dations and performance measures. The recom-mendations included antihypertensive agents in children; renin- angiotensin system inhibition (RASi) versus non-RASi in adults; intensive versus standard blood pressure targets; early versus late assessment for kidney replacement therapy (KRT); late versus early preparation strategies for KRT; CKD symptoms during assessment for KRT or conservative manage-ment; initiation of KRT in patients with deteriorating CKD; choice of KRT modality or conservative management in certain CKD patient groups; changing or discontinuing KRT modalities; the frequency of reviews for KRT or conservative management; and information, education, and support. These conditional recommendations were based on a low to very low certainty of evidence, which highlights the need for high-quality randomized trials com-paring different antihypertensive agents in patients with CKD.

Efficacy and safety of olmesartan medoxomil-amlodipine besylate tablet in Chinese patients with essential hypertension: A prospective, single-arm, multi-center, real-world study.

There lacks real-world study with a large sample size assessing olmesartan medoxomil-amlodipine besylate (OM-AML) tablet. Therefore, this study aimed to evaluate the efficacy and safety of OM-AML tablet in patients with essential hypertension. Totally, 1341 patients from 36 medical centers with essential hypertension who took OM-AML (20/5mg) tablet were analyzed in the current prospective, single-arm, multi-center, real-world study (SVK study). Seated systolic blood pressure (SeSBP) and seated diastolic blood pressure (SeDBP) at baseline, week (W)4 and W8 were measured. The mean (±SE) change of SeSBP/SeDBP was -10.8±0.4/-6.6±0.3mmHg at W4 and -12.7±0.5/-7.6±0.3mmHg at W8, respectively. At W4, 78.8% and 29.0% patients achieved BP target by China and American Heart Association (AHA) criteria; at W8, 84.7% and 36.5% patients reached blood pressure (BP) target by China and AHA criteria, accordingly. Meanwhile, 80.2% and 86.4% patients achieved BP response at W4 and W8, respectively. Home-measured SeSBP and SeDBP decreased from W1 to W8 (both p<.001). Besides, patients' and physicians' satisfaction were elevated at W8 compared with W0 (both p<.001). The medication possession rate was 94.8% from baseline to W4 and 91.3% from baseline to W8. The most common drug-related adverse events were nervous system disorders (4.6%), vascular disorders (2.6%), and general disorders and administration site conditions (2.3%) by system organ class, which were generally mild and manageable. In conclusion, OM-AML tablet is one of the best antihypertensive agents in patients with essential hypertension.

Hyperuricemia and Gout: The Role of Losartan.

Losartan is the only angiotensin II receptor blocker that has shown to significantly lower uric acid levels. The addition of or switch to losartan as an antihypertensive agent for patients with gout is recommended by clinical guidelines because of its benefit as a uricosuric agent.

Ocedurenone: A Novel Therapy for Uncontrolled Hypertension in Advanced Chronic Kidney Disease

Patients with advanced-stage chronic kidney disease (CKD) have a high burden of disease, which is compounded by serious comorbidities, including diabetes, cardiovascular disease (CVD), and, most commonly, hypertension. Control of hypertension is vital in patients with advanced CKD to reduce the associated risks of morbidity and mortality, but treatment options are limited, largely due to safety concerns for the use of existing antihypertensive agents in patients with poor renal function. During interviews conducted by EMJ in November 2022, two leading specialists in nephrology and cardiology, George Bakris, American Heart Association Comprehensive Hypertension Center, Department of Medicine, The University of Chicago Medicine, Illinois, USA, and Faiez Zannad, Clinical Investigation Centre (CIC 1493 Inserm-CHU), Université de Lorraine, Nancy, France; and Regional and University Hospital Center (CHRU) Nancy, France, discussed the challenges of treating uncontrolled hypertension in advanced CKD. These two experts described the complicated relationship between cardiovascular and renal disease, and identified significant unmet needs for patients with uncontrolled hypertension and advanced CKD. In this context, new agents in the field were viewed with interest, including the emerging class of non-steroidal mineralocorticoid receptor antagonists (MRA). The experts highlighted data from recent studies on the novel non-steroidal MRA, ocedurenone (KBP-5074), and discussed its potential as a treatment for uncontrolled hypertension in patients with advanced CKD.

PS-C20-4: SGLT2I - A POTENTIAL ANTIHYPERTENSIVE AGENT IN HYPERTENSION PATIENTS WITH TYPE 2 DIABETES MELLITUS

Introduction: Sodium-Glucose cotransporter 2 inhibitor is a class of treatment for type 2 diabetes mellitus (T2DM) recently recommended in the treatment of patients with heart failure. We evaluated the effect of blood pressure-lowering of this agent in patients with T2DM. Methods: A prospective study in all hypertensive patients with T2DM admitted to the Department of Cardiology Department of Hue Central Hospital who had not been treated with SGLT2i between 12/2020 and 05/2021. In the end, 236 patients were participating in the study, in which 110 patients received Dapagliflozin 10 mg daily with OMT and 126 patients received OTM. The patients were followed up at the hospital and 2 months after discharge. Comprehensive examination, and measurement of upper arm blood pressure (BP) with Omron HEM-7121. Results and discussion: The mean age was 66.77 ± 15.53. The patient had a 9 (0–40) year history of hypertension and a 5 (0–37) year history of T2DM. The baseline BP was 146.29 ± 19.17 / 83.78 ± 13.1 mmHg, with no significant difference in baseline BP values in the 2 groups of patients. The results after 2 months showed that in the group of patients in combination with SGLT2i, there was a significant decrease in the mean SBP value compared with the group of patients with OTM of 5.95 mmHg (95%CI: 2.08 - 9.82, p = 0.003) but the decrease in DBP was not significantly different (95% CI: -0.09 - 5.40, p = 0.058). Subgroup analysis showed that in the group of patients with resistant hypertension, the group of patients using SGLT2i reduced DBP more than the group of patients with OTM by 2.77 mmHg (95%CI: 1.89 - 4.24, p = 0.005) but was not significant for SBP. In contrast, in patients with isolated systolic hypertension, the SBP in the group of patients using SGLT2i decreased more than in the group without using SGLT2i by about 8.91 mmHg (95%CI: 6.20 - 11.24, p = 0.035). These results were not observed in patients with heart failure and chronic kidney disease. Conclusion: SGLT2i has shown potential to be used as an antihypertensive agent in patients with heart failure and chronic kidney disease and shows superior efficacy in patients with isolated systolic pressure and resistant hypertension.

Comparative Safety and Effectiveness of Aldosterone Antagonists Versus Beta-Blockers as Fourth Agents in Patients With Apparent Resistant Hypertension.

Limited evidence exists regarding long-term effectiveness and safety of aldosterone antagonists (AAs) versus beta blockers (BBs) as fourth-line antihypertensive agents in patients with resistant hypertension (RH). We evaluated the comparative effectiveness and safety of aldosterone AA versus BB. We conducted a real-world retrospective cohort study using IBM MarketScan commercial claims and Medicare Supplemental claims (2007-2019). Patients with RH entered the cohort (ie, index date) when they newly initiated either AA or BB. The effectiveness outcome was major adverse cardiovascular events. Safety outcomes were hyperkalemia, gynecomastia, and kidney function deterioration. Potential confounding was addressed by adjustment for baseline characteristics via stabilized inverse probability of treatment weighting (SIPTW) based on propensity scores. Cox proportional hazards regression with SIPTWs were used to estimate adjusted hazard ratio (aHR) and 95% CI comparing risk for outcomes between AA and BB groups. We identified 80 598 patients with RH (mean age: 61 years, 51% males), of which 6626 initiated AA and 73 972 initiated BB as the fourth antihypertensive agent. Among patients with RH, initiation of AA as a fourth-line antihypertensive agent did not significantly reduce major adverse cardiovascular event risk relative to BB initiation (aHR, 0.77 [95% CI, 0.50-1.19]) but did substantially increase the risk of hyperkalemia (aHR, 3.86 [95% CI, 2.78-5.34]), gynecomastia (aHR, 9.51 [95% CI, 5.69-15.89]), and kidney function deterioration (aHR, 1.63 [95% CI, 1.34-1.99]). Long-term clinical trials powered to assess major adverse cardiovascular events are necessary to understand the risk-benefit trade-off of AA as fourth-line therapy for RH.

Systolic Blood Pressure Variability When Transitioning From Intravenous to Enteral Antihypertensive Agents in Patients With Hemorrhagic Strokes.

Background/ObjectiveSystolic blood pressure variability (SBPV) in patients with intracranial hemorrhage (ICH) and subarachnoid hemorrhage (SAH) is associated with an increased risk of acute kidney injury (AKI) and mortality. SBPV is a strong predictor of poor functional outcomes in patients with ICH. Intravenous (IV) antihypertensive agents are commonly used to achieve sustained target blood pressure goals; however, this is not a feasible long-term option. The transition from IV to enteral antihypertensives is not yet well established in patients with ICH and SAH. This study aimed to assess the effect of the number of antihypertensive agents and overlap time during the transition period from IV to enteral route on SBPV in patients with ICH and SAH.MethodsThis retrospective single-center study was conducted at a tertiary teaching hospital in Riyadh, Saudi Arabia. Data were extracted from electronic medical records after obtaining Institutional Review Board approval. Patients were included if they were >18 years old, admitted with spontaneous ICH or SAH, and received continuous infusion antihypertensives prior to transitioning to the enteral route. The major outcome was the effect of the number of antihypertensive agents and overlap time on SBPV during the transition process. Minor outcomes included the effect of the number of antihypertensive agents and overlap time on heart rate variability and the incidence of AKI on day 7.ResultsAfter the screening, we included 102 patients. Based on our regression model, the number of enteral antihypertensive agents upon transitioning from IV to enteral antihypertensive therapy had no effect on SBPV in the intensive care unit (ICU) among our patients (p-value = 0.274). However, the prolonged overlap was associated with reduced SBPV in the ICU (p-value = 0.012). No differences were observed between the groups in heart rate variation or AKI rate.ConclusionsIn patients with ICH and SAH, prolonged overlap of enteral antihypertensive agents to overlap with intravenous antihypertensive therapy may result in lower SBPV. This finding needs to be confirmed on a larger scale with more robust study designs for patients with ICH and SAH.

THE RENIN-ANGIOTENSIN SYSTEM INHIBITORS IN HAEMODIALYSIS: CARDIOPROTECTIVE? TO WHAT EXTENT?

Objective: The renin-angiotensin-aldosterone (RAAS) system is one of the most important systems in the pathogenesis of coronary heart disease. Its blockage constitutes a central pillar of cardiovascular therapeutics. Patients in end-stage renal disease or on dialysis are almost invariably excluded from trials evaluating antihypertensive treatments. Angiotensin-converting enzyme (ACE) inhibitors or angiotensin II receptor blockers (ARBs) are more cardioprotective than other antihypertensive agents in patients with chronic renal disease but whether this applies also to patients on dialysis is unknown. This study followed a cohort of haemodialysis patients over a median of three years, we analysed all-cause mortality and cardio-vascular admissions for patients under RAAS inhibitors. Design and method: Twenty-seven HD patients were cross-sectionally analysed in the following groups: G1: patients with hypertension under ACE or ARB treatment (n = 10), G2: patients with hypertension under another class (n = 7), G3: non-hypertensive patients (n = 10). Associations with all-cause and cardiovascular mortality were assessed over a median of 3 years of follow-up. Results: Overall we had three homogeneous groups, there was no significant difference between median ages (46,3 vs52,7 vs49,9), initial nephropathy or dialysis vintage (5,9 years vs 5,1 vs 11,4). In G1: 4 patients experienced cardiovascular events (40%), but none of them died of cardiovascular causes/complications. In G2: 4 patients had cardiovascular events (57%) amongst whom two died of its complications. In G3: two patients had cardiovascular events (20%) amongst whom one died. There was statistically no significant difference between our groups in terms of cardiovascular morbidity or mortality and in all-causes mortality. Nevertheless, patients under SRA inhibitors presented the lowest number of cardiovascular mortalities. Conclusions: In the study, we observed that patients with SRA inhibitors experienced less cardio-vascular related death, although it is not enough to conclude its cardioprotective status. Larger studies need to be carried to unveil its utility among haemodialysis patients.

SGLT2I - A POTENTIAL ANTIHYPERTENSIVE AGENT IN HYPERTENSION PATIENTS WITH TYPE 2 DIABETES MELLITUS

Objective: Sodium Glucose cotransporter 2 inhibitor is a class of treatment type 2 diabetes mellitus (T2DM) recently recommended in treatment patient with heart failure. We evaluated the effect of BP lowering of this agent in patients with T2DM. Design and method: A prospective study in all hypertensive patients with T2DM admitted to Cardiology Department of Hue Central Hospital between 12/2020 and 05/2021 who had not been treated with SGLT2i. There were 236 patients don’t meet exclusion criterias, in which 110 patients received Dapagliflozin 10 mg daily with OMT and 126 patients received OTM. The patients were followed up at the hospital and 2 months after discharge. Measurement of upper arm blood pressure (BP) with Omron HEM-7121. Results: The mean age was 66.77 ± 15.53. The patient had 9 (0–40) year history of hypertension and 5 (0–37) year history of T2DM. The baseline BP was 146.29 ± 19.17 / 83.78 ± 13.1 mmHg, no significant difference in baseline BP in the 2 groups of patients. The results after 2 months showed, in the group of patients in with SGLT2i, there was a significant decrease in the mean SBP value compared with the group of patients with OTM of 5.95 mmHg (95%CI: 2.08 - 9.82, p = 0.003) but the decrease in DBP was not significantly different (95% CI: -0.09 - 5.40, p = 0.058). Subgroup analysis showed that in the group of patients with resistant hypertension, the group of patients using SGLT2i reduced DBP more than the group of patients with OTM by 2.77 mmHg (95%CI: 1.89 - 4.24, p = 0.005) but was not significant for SBP. In contrast, in the group of patients with isolated systolic hypertension, the SBP in the group of patients using SGLT2i decreased more than the group of patients without using SGLT2i about 8.91 mmHg (95%CI: 6.20 - 11.24, p = 0.035). These results were not observed in patients with heart failure and CKD. Conclusions: SGLT2i has shown potential to be used as an antihypertensive agent in patients with heart failure and chronic kidney disease and shows dominant efficacy in patients with isolated systolic pressure and resistant hypertension.

Drug utilization study of anti-hypertensive drugs and prescription pattern adherence with joint national committee-8 guideline

Background: Hypertension is a major and serious non-communicable disease. It is also a major risk factor for cerebrovascular strokes, coronary artery thrombosis, and renal failure. The overall prevalence of hypertension in India is 29.8%. Joint national committee-8 guidelines on prevention, detection, evaluation, and treatment of high blood pressure highlight that aggressive blood pressure control is essential for the reduction of hypertension-associated morbidity and mortality.Methods: It was a cross-sectional, observational study. Prescriptions were collected from four pharmacy stores located in four different areas of Ahmedabad over a period of 2 months. These were analysed along with relevant co-morbidities and, the level of prescription pattern adherence was assessed as per JNC 8 guidelines. Appropriate statistical tests were applied for analyses of collected data.Results: A total of 321 prescriptions were collected. Out of them, 186(57.9%) were prescribed to male patients while 135 (42.1%) were for female patients. Mean systolic and diastolic blood pressure was found to be 152 mmHg and 91 mmHg respectively. The mean age of the patients was found to be 44.63 years. A total of 209 (65.1%), 91 (28.34%), 21 (6.54%) prescriptions had monotherapy, dual therapy, and polytherapy for treating hypertension respectively. Amlodipine (CCBs) was found to be the most commonly prescribed medicine as a monotherapy. The overall adherence rate was found to be 77.88%.Conclusions: The present study demonstrated that medical professionals are not completely adhering to standard guidelines while prescribing antihypertensive drugs. There is substantial scope for improvement, particularly the utilization of antihypertensive agents in patients of the pre-hypertension category, where non-pharmacological measures play an important role to treat the condition.

Efficacy of angiotensin receptor neprilysin inhibitor in Asian patients with refractory hypertension

Sacubitril/valsartan, simultaneously inhibits neprilysin and angiotensin II receptor, showed an effect in reducing blood pressure (BP). The authors aimed to study whether it can be used as an antihypertensive agent in patients with refractory hypertension who have already been treated. A total of 66 Chinese patients with refractory hypertension were enrolled. Patients received sacubitril/valsartan 200 instead of angiotensin II receptor blocker or angiotensin converting enzyme inhibitor while other agents continued. If BP was uncontrolled after 4 weeks, sacubitril/valsartan was increased to 400 mg. The BP reduction was evaluated by office BP and ambulatory BP monitoring after 8‐week treatment. The baseline office BP and mean arterial pressure (MAP) were 150.0/95.0 mmHg and 113.3 mmHg. BP and MAP reduced to 130.6/83.2 mmHg and 99.0 mmHg at week 8. Office BP and MAP reductions were 19.4/11.8 mmHg and 14.3 mmHg at endpoint (all p < .001). The 24‐h, daytime and nighttime ambulatory BP were 146.2/89.1, 148.1/90.3, and 137.5/83.7 mmHg, respectively at baseline, and BP reduced to 129.6/79.8, 130.6/81.1, and 121.7/75.8 mmHg, respectively at week 8. The 24‐h, daytime and nighttime ambulatory BP reductions were 16.6/9.3, 17.5/9.2, and 15.8/7.9 mmHg, respectively at endpoint (all p < .001). Sacubitril/valsartan significantly reduced office and ambulatory BP in refractory hypertension patients. Our study provided new evidence for sacubitril/valsartan in refractory hypertension.

Drug Utilization Patterns of Anti Hypertensive agents in patients undergoing Hemodialysis in a Tertiary Care Hospital

Background: India is experiencing a rapid health transition and is projected to become a major reservoir of chronic diseases like Diabetes and Hypertension and 25 to 40% of these subjects may develop chronic kidney disease and end stage renal disease. Aim and objective of the study was to analyze utilization pattern of antihypertensive drugs in chronic kidney disease patients in a tertiary care hospital. Methods: The present observational cross-sectional study was conducted in Apollo hospitals, Jubilee hills, Hyderabad from 01.12.2019 to 31.05.2020 on patients with chronic kidney disease stage 5. The drug utilization pattern was studied with respect to age, sex, basic disease, duration of dialysis, type of antihypertensives used, etc. Comparison of mean between gender and dialysis / not on dialysis was done using unpaired ‘t’ test. A p value of &lt; 0.05 was taken as statistically significant. Results: Of 100 patients, the data was analyzed with respect to age categories between 18-30 years; 31-40; 41-50; 51-60; 61-70; &gt;70 years which accounted for 10%, 11%, 20%, 35%, 21% and 3% respectively. The patients between age group between 51-60 years were more prevalent compared to other age groups, based on gender distribution, majority of sample size were found to be males (62%) followed by females (38%). In our study sample, few subjects were found to be Overweight and obese subjects accounted for 33% and 20% respectively followed by subjects with normal BMI 44% and Underweight 3%.Almost all the subjects had Comorbidities. The profound ones were Dyslipidemia, Diabetes mellitus, Hypothyroid, CAD. The contribution of hypertension to medical morbidity and mortality is therefore enormous as it has been shown in other studies with stroke, anemia, Type 2 DM, and renal failure. It is the most common associated comorbid condition among many medical admissions. Most clinicians are often guided by their preference for any of the major guidelines available for the management of hypertension. Previously, diuretics were considered to be the first-line drugs. However, guidelines by the JNC VII recommend both CCBs as well as ACE-I as first-line drugs in addition to diuretics. Conclusions: In order to treat CKD, it is important to treat hypertension as hypertension and CKD are related to each other. Treatment of hypertension will help in controlling future development of comorbidities. Calcium channel blockers and centrally acting drugs are the treatment of choice in patients with CKD stage 5D with hypertension. Multi-drug antihypertensive therapy is a better choice than mono/single-drug antihypertensive therapy.

Effect of sodium-glucose cotransporter-2 inhibitors on patients with essential hypertension and pre-hypertension: a meta-analysis.

Sodium-glucose cotransporter-2 (SGLT2) inhibitors are novel, hypoglycemic drugs exhibiting cardiovascular protective activities. If SGLT2 inhibitors can be successfully used as antihypertensive drugs, they can be administered to patients with both hypertension and type 2 diabetes, thus diminishing the risk of polypharmacy-related complications. The aim of this review was to evaluate the hypotensive efficacy of SGLT2 inhibitors in patients with hypertension and pre-hypertension. We systematically searched PubMed, Embase, and Cochrane for randomized controlled trials comparing SGLT2 inhibitors and a placebo in patients with essential hypertension and pre-hypertension. Our main outcome was the mean change in office blood pressure (BP) and body weight. We assessed the pooled data using a fixed-effects model. After screening 968 articles, nine trials were eligible (n = 2450 participants). Compared to the mean changes in systolic and diastolic BP in patients who were given a placebo, those in patients who used SGLT2 inhibitors were -5.04 mmHg and -1.67 mmHg, respectively. An intensive dose of SGLT2 inhibitors resulted in a stronger BP-lowering effect than the regular dose. Compared to that in the placebo group, the mean change in mean body weight was -1.74 kg in the SGLT2 inhibitor group. There was no significant difference between the two groups regarding the risk of overall adverse events. The pooled effect estimates remained similar across all residual studies and their subgroups in the leave-one-out sensitivity analysis. SGLT2 inhibitors had a statistically significant BP-lowering effect on hypertension and pre-hypertension, which was further enhanced with increased drug dosage. SGLT2 inhibitors have the potential to be used as antihypertensive agents in patients with hypertension complicated by type 2 diabetes.

Is Hypertension Despite Use of Two or More Anti-hypertensive Medications for Patients with a BMI < 40 kg/m2 Justified for Eligibility for Bariatric Surgery?

Several insurance policies require the presence of hypertension, defined as blood pressure > 140 mmHg systolic (SBP), or 90 mmHg diastolic (DBP), despite concurrent use of >1 anti-hypertensive agents for patients with a BMI <40 kg/m2 to qualify for bariatric surgery (BS). The scientific validity of this requirement is assessed. A total of 461 patients who underwent BS in a community hospital were included. Systolic (SBP) and diastolic (DBP) blood pressure BP (in mmHg) was assessed by an automated manometer at each office visit until 3 years postoperatively and recorded in a prospectively maintained database. Thirty-six (7.8%) patients with BMI <40 Kg/m2, treated by 1, 2, or three anti-hypertensive medications and BP below 140/90, would have been denied BS under such policies. Number of anti-hypertensive medications had no impact on SBP/DBP control preoperatively. Patients being treated preoperatively with < 3 anti-hypertensive medications had a significantly higher percentage of hypertension resolution at 1 (one-med: 66.2%, two-med: 50.9% vs. three-med: 12.5%, p<.0001), 2 (one-med: 63.9%, two-med: 52.8% vs. three-med: 15.4%, p=.0068), and 3 (one-med: 76.9%, two-med: 52.9% vs. three-med: 20%, p=.005) years postoperatively. Multivariate regression demonstrated a significant correlation between the number of preoperative anti-hypertensive medications, preoperative SBP or DBP, and %TBWL. Patients treated with fewer than 3 anti-hypertensive medications did not have a better BP control preoperatively but were more likely to resolve their hypertension postoperatively. Restricting access to BS of patients with hypertension treated by fewer than 3 anti-hypertensive medications is not supported by this study.

Efficacy of angiotensin receptor neprilysin inhibitor in Asian patients with refractory hypertension

Abstract Background Angiotensin receptor neprilysin inhibitor, concomitantly inhibits neprilysin and angiotensin type 1 receptor shown an effect of reducing blood pressure. We aimed to study whether it can be used as an antihypertensive agent in patients with resistant hypertension who has already been treated. Methods This is a multiple center prospective study. Thirty-five Chinese patients with refractory hypertension were enrolled. Resistant hypertension was defined as on the basis of improved lifestyle when the application of the three reasonable and tolerable dose of antihypertensive drugs including thiazide diuretics at least four weeks after treatment, the inadequate control of BP is confirmed by ambulatory BP monitoring, or at least four drugs are needed to achieve the BP standard. Refractory hypertensive patient received sacubitil/valsartan 200 mg instead of their angiotensin type 1 receptor blocker while other agents were continued. If blood pressure was uncontrolled, the sacubitil/valsartan dose was increased to 400 mg after 4 weeks. ABPM were evaluated at 8 weeks follow up. Results Reductions in office SBP/DBP at week 8 were 37/17 mmHg. the average baseline ABPM were 154/90 mmHg of 24-h, and daytime BP and nighttime BP were 157/92 mmHg and 145/83 mmHg respectively. he average endpoint ABPM were 134/80 mmHg of 24-h, and daytime BP and nighttime BP were 136/82 mmHg and 125/73 mmHg respectively. Reductions in 24-h ABPM at week 8 were 20/9 mmHg while 20/10 mmHg in daytime and 20/9 mmHg in nighttime. Conclusion The sacubitil/valsartan provided a strategy therapy for refractory hypertension in Chinese patients in reducing SBP and DBP. Funding Acknowledgement Type of funding sources: None.

Association of antihypertensives during hospitalisation with acute respiratory failure in patients with viral pneumonia: A population-based case-control study.

We aimed to identify associations between the risk of acute respiratory failure (ARF) and types of antihypertensive agents in patients with viral pneumonia. In this case-control study, data extracted from the Taiwan National Health Insurance Research Database were analysed. The base population comprised patients with viral pneumonia treated from 2000 to 2013. The case group comprised patients with ARF and the control group comprised participants without ARF. Adjusted odds ratios (ORs) were calculated using a multivariable logistic regression model. In total, 4427 viral pneumonia patients with ARF and 4427 matched control participants without ARF were recruited. Patients with diabetes, alcohol-related disease, asthma, chronic kidney disease or end-stage renal disease, chronic obstructive pulmonary disease, cancer, congestive heart failure, stroke, acute pulmonary oedema and shock had increased odds of developing ARF, especially shock (adjusted OR=49.3; 95% CI=27.4, 88.7), cancer (12.6; 8.67, 18.2) and stroke (7.51; 5.32, 10.6). Increasing odds of developing ARF were noted in patients using potassium-sparing diuretics (2.95; 1.54, 5.64), loop diuretics (68.2; 48.1, 96.6), calcium channel blockers (1.64; 1.26, 2.13) and angiotensin-converting enzyme inhibitors (1.70; 1.15, 2.53). Patients with prescriptions of α-blockers (0.44; 0.26, 0.74), β-blockers (0.37; 0.26, 0.52), thiazides (0.38; 0.25, 0.59) and angiotensin receptor blockers (0.65; 0.51, 0.83) had lower odds of having ARF. Patients with viral pneumonia who received α-blockers, β-blockers, thiazides or angiotensin receptor blockers during hospitalisation had a lower risk of developing ARF.

Association of Antihypertensive Agents with the Risk of In-Hospital Death in Patients with Covid-19.

PurposeThe role of angiotensin receptor blockers (ARB), angiotensin-converting enzyme inhibitors (ACEi), or other antihypertensive agents in the case of Covid-19 remains controversial. We aimed to investigate the association between antihypertensive agent exposure and in-hospital mortality in patients with Covid-19.MethodsWe performed a retrospective multicenter cohort study on patients hospitalized between February 1 and May 15, 2020. All patients had been followed up for at least 30 days.ResultsOf the 8078 hospitalized patients for Covid-19, 3686 (45.6%) had hypertension and were included in the study. In this population, the median age was 75.4 (IQR, 21.5) years and 57.1% were male. Overall in-hospital 30-day mortality was 23.1%. The main antihypertensive pharmacological classes used were calcium channel blockers (CCB) (n=1624, 44.1%), beta-blockers (n=1389, 37.7%), ARB (n=1154, 31.3%), and ACEi (n=998, 27.1%). The risk of mortality was lower in CCB (aOR, 0.83 [0.70–0.99]) and beta-blockers (aOR, 0.80 [0.67–0.95]) users and non-significant in ARB (aOR, 0.88 [0.72–1.06]) and ACEi (aOR, 0.83 [0.68–1.02]) users, compared to non-users. These results remain consistent for patients receiving CCB, beta-blocker, or ARB as monotherapies.ConclusionThis large multicenter retrospective of Covid-19 patients with hypertension found a reduced mortality among CCB and beta-blockers users, suggesting a putative protective effect. Our findings did not show any association between the use of renin-angiotensin-aldosterone system inhibitors and the risk of in-hospital death. Although they need to be confirmed in further studies, these results support the continuation of antihypertensive agents in patients with Covid-19, in line with the current guidelines.Supplementary InformationThe online version contains supplementary material available at 10.1007/s10557-021-07155-5.

Beta-blockers in hypertension: overview and meta-analysis of randomized outcome trials.

Meta-analyses from randomized outcome-based trials have challenged the role of beta-blockers for the treatment of hypertension. However, because they often include trials on diseases other than hypertension, the role of these drugs in the choice of the blood pressure (BP)-lowering treatment strategies remains unclear. Electronic databases were searched for randomized trials that compared beta-blockers vs. placebo/no-treatment/less-intense treatment (BP-lowering trials) or beta-blockers vs. other antihypertensive agents in patients with or without hypertension (comparison trials). Among BP-lowering trials and according to baseline comorbidity, we separately considered trials in hypertension, trials without chronic heart failure or acute myocardial infarction, and trials with either chronic heart failure or acute myocardial infarction. Seven fatal and nonfatal outcomes were calculated (random-effects model) for BP-lowering or comparison trials. A total of 84 BP-lowering or comparison trials (165 850 patients) were eligible. In 67 BP-lowering trials (68 478 patients; mean follow-up 2.5 years; baseline SBP/DBP, 136/82 mmHg), beta blockers were associated with a lower incidence of major cardiovascular events [risk ratio 0.85 and 95% confidence interval (95% CI) 0.78-0.92] and all-cause death (risk ratio 0.81 and 95% CI 0.75-0.86). Restriction of the analysis to five trials recruiting exclusively hypertensive patients (18 724 patients; mean follow-up 5.1 years; baseline SBP/DBP 163/94 mmHg), a -10.5/-7.0 mmHg BP decrease was accompanied by reduction of major cardiovascular events by 22% (95% CI, 6-34). In 24 comparison trials (103 764 patients, 3.92 years of mean follow-up), beta-blockers compared with other agents were less protective for stroke and all-cause death in all trials and in trials conducted exclusively in hypertensive patients (averaged risk ratio increase 20 and 6%, respectively, for both cases). Compared with other antihypertensive agents, beta-blockers appear to be substantially less protective against stroke and overall mortality. However, they exhibit a substantial risk-reducing ability for all events when prescribed to lower BP in patients with modest or more clear BP elevations, and therefore can be used as additional agents in hypertensive patients.

P0178COMPARATIVE EFFECTIVENESS OF RENIN-ANGIOTENSIN SYSTEM INHIBITORS AND CALCIUM CHANNEL BLOCKERS IN INDIVIDUALS WITH ADVANCED CHRONIC KIDNEY DISEASE: A NATIONWIDE COHORT STUDY

Abstract Background and Aims There is a lack of data that could help to guide the choice of antihypertensive agents in patients with advanced chronic kidney disease (CKD). We evaluated whether initiating treatment with a renin-angiotensin system inhibitor (RASi) is superior to calcium channel blockers (CCB) in preventing mortality, major adverse cardiovascular events (MACE) or kidney replacement therapy (KRT) in patients with advanced CKD. Method Observational study from the Swedish Renal Register, 2007-2017. We identified all nephrologist-referred patients in Sweden who initiated RASi or CCB treatment and had non-dialysis dependent advanced CKD (eGFR &amp;lt;30 ml/min/1.73m2). The associations between RASi vs CCB initiation, mortality, MACE and KRT were assessed by Cox regression. Analyses were adjusted with propensity score weighting for a wide range of confounders, including demographics, blood pressure, laboratory measures, comorbidities and medications. As a positive control we evaluated new use of the same drugs in patients with CKD G3 (N = 2608; eGFR between 30-60 ml/min/1.73m2). Furthermore subgroup, as-treated and competing risk analyses were performed. Results The propensity-score weighted cohort included 2479 RASi and 2327 CCB initiators who were well-matched for baseline confounders (all standardized differences &amp;lt;0.1). Median follow-up was 4.1 years, with a maximum follow-up of over 10 years. Compared to CCB, initiation of RASi was associated with a similar risk of mortality (adjusted HR 0.94; 95% CI 0.85-1.03) and MACE (0.99; 0.87-1.13), but with a lower risk of KRT (0.87; 0.78-0.98). Results were consistent across subgroups, in as-treated analyses and after accounting for the competing risk of death. In the control cohort of patients with CKD G3, initiation of RASi (versus CCB) was associated with lower KRT risk (adjusted HR 0.67; 0.47-0.96), and similar risk of mortality (0.91; 0.76-1.08) and MACE (1.06; 0.82-1.35). Conclusion Compared with CCB, initiation of RASi in patients with advanced CKD was associated with a lower risk of KRT, but no different risk of mortality or MACE.
