Impacto económico del uso de patiromer en enfermedad renal crónica o insuficiencia cardíaca para el tratamiento de la hiperpotasemia crónica en España / Economic impact of the use of patiromer in chronic kidney disease or heart failure for the treatment of chronic hyperkalemia in Spain

Introducción La hiperpotasemia crónica tiene consecuencias negativas a medio y largo plazo, condicionando generalmente la suspensión de fármacos nefro y cardioprotectores, en pacientes con enfermedad renal crónica (ERC) e insuficiencia cardíaca (IC), como son los inhibidores del sistema renina-angiotensina-aldosterona. Existe una alternativa a la suspensión o reducción de dosis de estos tratamientos y es la administración de quelantes del potasio. El objetivo de este estudio es estimar el impacto económico que supondría el uso de patiromer en pacientes con ERC o IC e hiperpotasemia en España. Material y métodos Se ha estimado el impacto económico anual del uso de patiromer desde la perspectiva de la sociedad española, comparando 2 escenarios: pacientes con ERC o IC e hiperpotasemia tratada con patiromer y sin patiromer. Los costes se han actualizado a euros de 2020, utilizando el índice de precios de consumo de Sanidad. Se han considerado los costes directos sanitarios relacionados con el uso de recursos (el tratamiento con inhibidores del sistema renina-angiotensina-aldosterona, la progresión de la ERC, los eventos cardiovasculares y la hospitalización por hiperpotasemia), los costes directos no sanitarios (cuidados informales: costes derivados del tiempo de dedicación por parte de los familiares del paciente), los costes indirectos (pérdidas de productividad laboral), así como un coste intangible (por mortalidad prematura). Se realizó un análisis de sensibilidad determinístico para validar la consistencia de los resultados del estudio. Resultados El coste medio anual por paciente en el escenario sin patiromer es de 9.834,09 € y 10.739,37 € en ERC e IC, respectivamente. El uso de patiromer supondría un ahorro de costes superior al 30% en ambas enfermedades. En el caso de la ERC, el mayor ahorro procede del retraso de la progresión de la ERC (AU)

Introduction Chronic hyperkalemia has negative consequences in the medium and long term, and determines the suspension of nephro and cardioprotective drugs, such as renin–angiotensin–aldosterone system inhibitors (RAASi). There is an alternative to the suspension or dose reduction of these treatments: the administration of potassium chelators. The aim of this study is to estimate the economic impact of the use of patiromer in patients with chronic kidney disease (CKD) or heart failure (HF) and hyperkalemia in Spain. Materials and method The annual economic impact of the use of patiromer has been estimated from the perspective of the Spanish society. Two scenarios were compared: patients with CKD or HF and hyperkalemia treated with and without patiromer. The costs have been updated to 2020 euros, using the Health Consumer Price Index. Direct healthcare costs related to the use of resources (treatment with RAASi, CKD progression, cardiovascular events and hospitalization due to hyperkalemia), direct non-healthcare costs (informal care: costs derived from time dedicated by patient's relatives), the indirect costs (productivity loss), as well as an intangible cost (due to premature mortality) were considered. A deterministic sensitivity analysis was performed to validate the robustness of the study results. Results The mean annual cost per patient in the scenario without patiromer is €9834.09 and €10,739.37 in CKD and HF, respectively. The use of patiromer would lead to cost savings of over 30% in both diseases. The greatest savings in CKD come from the delay in the progression of CKD. While in the case of HF, 80.1% of these savings come from premature mortality reduction. The sensitivity analyses carried out show the robustness of the results, obtaining savings in all cases (AU)

Treatment and outcome of IgA nephropathy in children from one single center experience.

BACKGROUND: There is no standard recommendation for IgA nephropathy treatment in children. METHODS: This is a retrospective study. From 2012 to 2020, newly diagnosed primary IgAN followed up for at least 1 year were enrolled. The correlation of MESTC scores and clinical index including proteinuria, gross hematuria and renal dysfunction was analyzed. Treatment and clinical response of 6 month, 1year and 3 year at follow up were also analyzed. Complete renal remission was calculated with Kaplan-Meier analysis. RESULTS: The median follow up was 36 months, from 12 months to 87months in 40 IgAN children. Angiotensin-converting enzyme inhibitor (ACEI) was applied to all patients. 30% received ACEI alone; 15% received glucocorticoids; 37.5% received glucocorticoids plus cyclophosphamide, 17.5% received glucocorticoids plus mycophenolate mofetil. Individuals with diffuse mesangial hypercellularity (M1) were more likely to have nephrotic range proteinuria compared to patients with M0 (80% vs. 20%, P < 0.01). Complete renal remission at 6-month, 1-year and 3-year follow up is 50.25%, 70% and 87.5% respectively. Five-year complete renal remission calculated by Kaplan-Meier analysis is 58.4%. Although without significant difference, there is trend of better survival with complete renal remission in group of nephrotic range proteinuria onset. There is no severe adverse effect. CONCLUSION: This study supports the use of glucocorticoids plus immunosuppressive in addition to ACEI in IgA nephrology pediatric patients with proteinuria. We suggest proactive immunosuppressive treatment in IgA nephropathy in children. This is from a single center in China as may not same results in other population.

Combinação fixa de benazepril associado a anlodipino para adultos com hipertensão arterial sistêmica com controle inadequado da pressão arterial / Fixed combination of benazepril associated with amlodipine for adults with controlled systemic arterial hypertension inadequate blood pressure

INTRODUÇÃO: A hipertensão arterial sistêmica (HAS), uma doença crônica, é um grave problema de saúde pública, caracterizada por níveis elevados e persistentes da pressão sanguínea, medidos em geral como uma razão da pressão arterial sistólica e diastólica (respectivamente maior ou igual a 140 mmHg; e/ou maior ou igual a 90 mmHg). Esta é uma doença altamente prevalente em todo o mundo. No Brasil, os números podem variar de acordo com a metodologia utilizada. Reportou-se na Pesquisa Nacional de Saúde de 2013, cujos dados são obtidos por autorrelato, a prevalência de hipertensão em 21% dos pacientes, mas ao considerar a aferição da pressão arterial e uso de medicamentos, o percentual de adultos com pressão arterial ≥140/90 mmHg foi de 32%. Sabe-se que a falta de controle da pressão arterial pode elevar o risco de ocorrência de eventos cardiovasculares, como infarto agudo do miocárdio, insuficiência cardíaca, acidente vascular cerebral, doenças renais, entre outros. Isso consequentemente pode causar problemas crônicos que reduzem a qualidade de vida do indivíduo, e até mesmo o

Geriatric Pharmacotherapy Case Series: Recurrent Angioedema Following Discontinuation of ACE Inhibitor Therapy.

Introduction Angiotensin-converting enzyme inhibitors (ACEIs) are first-line pharmaceutical agents in common chronic conditions such as hypertension and heart failure with reduced ejection fraction. When angioedema occurs, if secondary to ACEIs, discontinuation of the ACEI is necessary to mitigate the risk of recurrent angioedema. While angioedema is a well-known adverse effect of ACEIs, it is not well-known that angioedema may recur even after ACEI discontinuation. Additionally, only few reports in the literature describe this phenomenon. This case describes an older man with a history of chronic obstructive pulmonary disease, hypothyroidism, diabetes mellitus, hypertension, and heart failure who presented from an assisted living facility with recurrent angioedema 12 days after an initial episode of angioedema where his ACEI therapy (enalapril) was discontinued. Assessment Empiric methylprednisolone, diphenhydramine, intramuscular epinephrine, intravenous C1 esterase inhibitor Berinert®, and two units of fresh frozen plasma was given in the emergency department. The patient was monitored in the intensive care unit because of mild airway compromise but did not require invasive airway protection. Serum C4 level was normal, ruling out hereditary angioedema. Outcome Patient was discharged after five days in stable condition with resolution of symptoms. Conclusion ACEIs are the most common cause of drug-induced angioedema in the United States. Angioedema is self-limiting swelling that requires close airway monitoring. While health professionals recognize the risk for angioedema with active ACEI use, it is not well known that the risk of angioedema may occur for months following cessation of ACEI therapy. Increased awareness of delayed ACEI-induced angioedema following ACEI discontinuation is important for both providers and pharmacists to provide appropriate diagnosis and monitoring. Improved awareness would also allow patients with a history of ACEI-induced angioedema to be cognizant of the potential for recurrence following drug discontinuation.

Role of Brain Angiotensin-II in Development of Experimental Diabetic Nephropathy in Wistar Rats

Abstract The renin-angiotensin-aldosterone system (RAAS) plays a key role in diabetic nephropathy (DN). Angiotensin-II secreted during the RAAS pathway increases nephropathy. It stimulates oxidative stress which can quench nitric oxide. Reduced nitric oxide level aggravates Ang-II-induced vasoconstriction. Ang-II has also emerged as a central mediator of the glomerular hemodynamic changes that are associated with renal injury. Deletion of ACE2 is also noted due to increased Ang-II level which leads to the development of DN. We hypothesize that nephropathy caused by Ang-II in the periphery may be controlled by brain RAAS. ACE inhibitors and ARBs may show the renoprotective effect when administered through ICV without crossing the blood-brain barrier. DN was observed after 8 weeks of diabetes induction through alloxan. Administration of captopril and valsartan once and in combined therapy for 2 weeks, significantly reduced urine output, blood urea nitrogen, total protein in the urine, serum cholesterol, serum creatinine, serum triglycerides, and kidney/body weight ratio as compared to diabetic control rats. Further, combination therapy significantly increased the body weight and serum nitrate level as compared to diabetic control animals. However, increased ACE2 levels in the brain may reduce the sympathetic outflow and might have decreased the peripheral activity of Ang-II which shows beneficial effects in DN.

Submaximal Angiotensin-Converting Enzyme Inhibitor and Angiotensin Receptor Blocker Dosing Among Persons With Proteinuria.

For persons with proteinuria, angiotensin-converting enzyme inhibitors (ACEis) and angiotensin II receptor blockers (ARBs) are treatment mainstays for reducing kidney disease progression. Guidelines for managing hypertension and chronic kidney disease recommend titrating to the maximum ACEi/ARB dose tolerated. Using deidentified national electronic health record data from the Optum Labs Data Warehouse, we examined ACEi/ARB dosing among adults with proteinuria-defined as either a urine albumin to creatinine ratio of 30 mg/g or greater or a protein to creatinine ratio of 150 mg/g or greater-who were prescribed an ACEi/ARB medication between January 1, 2017, and December 31, 2018. Among 100,238 included patients (mean age, 65.1 years; 49,523 [49.4%] female), 29,883 (29.8%) were taking maximal ACEi/ARB doses. Among 74,287 patients without potential contraindications to dose escalation (systolic blood pressure <120 mm Hg, estimated glomerular filtration rate <15 mL/min per 1.73 m2, serum potassium level greater than 5.0 mEq/L, or acute kidney injury within the prior year), the frequency of maximal ACEi/ARB dosing was 32.3% (24,025 patients). In adjusted analyses, age less than 40 years, female sex, Hispanic ethnicity, lower urine albumin to creatinine ratio, lack of diabetes, heart failure, lower blood pressure, higher serum potassium level, and prior acute kidney injury were associated with lower odds of maximal ACEi/ARB dosing. Having a prior nephrologist visit was not associated with maximal dosing. Our results suggest that greater attention toward optimizing the dose of ACEi/ARB therapy may represent an opportunity to improve chronic kidney disease care and reduce excess morbidity and mortality associated with disease progression.

Effect of angiotensin-converting enzyme inhibition on cardiovascular adaptation to exercise training.

Angiotensin-converting enzyme (ACE) activity may be one determinant of adaptability to exercise training, but well-controlled studies in humans without confounding conditions are lacking. Thus, the purpose of the present study was to investigate whether ACE inhibition affects cardiovascular adaptations to exercise training in healthy humans. Healthy participants of both genders (40 ± 7 years) completed a randomized, double-blind, placebo-controlled trial. Eight weeks of exercise training combined with placebo (PLA, n = 25) or ACE inhibitor (ACEi, n = 23) treatment was carried out. Before and after the intervention, cardiovascular characteristics were investigated. Mean arterial blood pressure was reduced (p < 0.001) by -5.5 [-8.4; -2.6] mmHg in ACEi , whereas the 0.7 [-2.0; 3.5] mmHg fluctuation in PLA was non-significant. Maximal oxygen uptake increased (p < 0.001) irrespective of ACE inhibitor treatment by 13 [8; 17] % in ACEi and 13 [9; 17] % in PLA. In addition, skeletal muscle endurance increased (p < 0.001) to a similar extent in both groups, with magnitudes of 82 [55; 113] % in ACEi and 74 [48; 105] % in PLA. In contrast, left atrial volume decreased (p < 0.05) by -9 [-16; -2] % in ACEi , but increased (p < 0.01) by 14 [5; 23] % in PLA. Total hemoglobin mass was reduced (p < 0.01) by -3 [-6; -1] % in ACEi , while a non-significant numeric increase of 2 [-0.4; 4] % existed in PLA. The lean mass remained constant in ACEi but increased (p < 0.001) by 3 [2; 4] % in PLA. In healthy middle-aged adults, 8 weeks of high-intensity exercise training increases maximal oxygen uptake and skeletal muscle endurance irrespective of ACE inhibitor treatment. However, ACE inhibitor treatment counteracts exercise training-induced increases in lean mass and left atrial volume. ACE inhibitor treatment compromises total hemoglobin mass.

Time until onset of acute kidney injury by combination therapy with "Triple Whammy" drugs obtained from Japanese Adverse Drug Event Report database.

Acute kidney injury (AKI) associated with "Triple Whammy" drug therapy consisting of renin-angiotensin system inhibitors, diuretics, and nonsteroidal anti-inflammatory drugs (NSAIDs) has been reported. There have been no reports investigating "Triple Whammy" drug therapy and the time to AKI onset using adverse drug events report databases. The aim of this study was to determine the relationship between the time to AKI onset and treatment with "Triple Whammy" drug therapy. We analyzed AKI cases registered in the Japanese Adverse Drug Event Report database. The data were analyzed using the Kaplan-Meier approach, generalized Wilcoxon tests, and Weibull distribution. AKI was reported in 18,415 cases, of which 7,466 cases used Triple Whammy drugs. All combinations of Triple Whammy drugs were associated with significantly higher odds ratios for reporting AKI. In Weibull analysis, AKI onset was early for most combination patterns of Triple Whammy drugs. The Kaplan-Meier approach showed that the treatment duration to AKI onset was much shorter in cases using NSAIDs; median onsets, 8 days for triple combination, 7 days for NSAIDs added to renin-angiotensin system inhibitors, 9 days for NSAIDs added to diuretics, 6 days for diuretics added to NSAIDs, and 9 days for NSAIDs alone. AKI associated with Triple Whammy drugs is likely to occur in the early stages of treatment, especially with concomitant NSAIDs. Patients should be monitored for the occurrence of AKI within the first 2 weeks.

Hydrogen Sulphide Release via the Angiotensin Converting Enzyme Inhibitor Zofenopril Prevents Intimal Hyperplasia in Human Vein Segments and in a Mouse Model of Carotid Artery Stenosis.

OBJECTIVE: Hypertension is a major risk factor for intimal hyperplasia (IH) and re-stenosis following vascular and endovascular interventions. Preclinical studies suggest that hydrogen sulphide (H2S), an endogenous gasotransmitter, limits re-stenosis. While there is no clinically available pure H2S releasing compound, the sulfhydryl containing angiotensin converting enzyme inhibitor zofenopril is a source of H2S. Here, it was hypothesised that zofenopril, due to H2S release, would be superior to other non-sulfhydryl containing angiotensin converting enzyme inhibitors (ACEi) in reducing intimal hyperplasia. METHODS: Spontaneously hypertensive male Cx40 deleted mice (Cx40-/-) or wild type (WT) littermates were randomly treated with enalapril 20 mg or zofenopril 30 mg. Discarded human vein segments and primary human smooth muscle cells (SMCs) were treated with the active compound enalaprilat or zofenoprilat. IH was evaluated in mice 28 days after focal carotid artery stenosis surgery and in human vein segments cultured for seven days ex vivo. Human primary smooth muscle cell (SMC) proliferation and migration were studied in vitro. RESULTS: Compared with control animals (intima/media thickness 2.3 ± 0.33 µm), enalapril reduced IH in Cx40-/- hypertensive mice by 30% (1.7 ± 0.35 µm; p = .037), while zofenopril abrogated IH (0.4 ± 0.16 µm; p < .002 vs. control and p > .99 vs. sham operated Cx40-/- mice). In WT normotensive mice, enalapril had no effect (0.9665 ± 0.2 µm in control vs. 1.140 ± 0.27 µm; p > .99), while zofenopril also abrogated IH (0.1623 ± 0.07 µm; p < .008 vs. control and p > .99 vs. sham operated WT mice). Zofenoprilat, but not enalaprilat, also prevented IH in human vein segments ex vivo. The effect of zofenopril on carotid and SMCs correlated with reduced SMC proliferation and migration. Zofenoprilat inhibited the mitogen activated protein kinase and mammalian target of rapamycin pathways in SMCs and human vein segments. CONCLUSION: Zofenopril provides extra beneficial effects compared with non-sulfhydryl ACEi in reducing SMC proliferation and re-stenosis, even in normotensive animals. These findings may hold broad clinical implications for patients suffering from vascular occlusive diseases and hypertension.

Angiotensin-Converting Enzyme Inhibitor and Angiotensin Receptor Blocker Use Associated with Reduced Mortality and Other Disease Outcomes in US Veterans with COVID-19.

OBJECTIVE: To determine the association between angiotensin-converting enzyme inhibitors (ACEIs) or angiotensin II receptor blockers (ARBs) use and coronavirus disease 2019 (COVID-19) severity and outcomes in US veterans. PATIENTS AND METHODS: We retrospectively examined 27,556 adult US veterans who tested positive for COVID-19 between March to November 2020. Logistic regression and Cox proportional hazards models using propensity score (PS) for weight, adjustment, and matching were used to examine the odds of an event within 60 days following a COVID-19-positive case date and time to death, respectively, according to ACEI and/or ARB prescription within 6 months prior to the COVID-19-positive case date. RESULTS: The overlap PS weighted logistic regression model showed lower odds of an intensive care unit (ICU) admission (odds ratio [OR] 95% CI 0.77, 0.61-0.98) and death within 60 days (0.87, 0.79-0.97) with an ACEI or ARB prescription. Veterans with an ARB-only prescription also had lower odds of an ICU admission (0.64, 0.44-0.92). The overlap PS weighted model similarly showed a lower risk of time to all-cause mortality in veterans with an ACEI or ARB prescription (HR [95% CI]: 0.87, 0.79-0.97) and an ARB only prescription (0.78, 0.67-0.91). Veterans with an ACEI prescription had higher odds of experiencing a septic event within 60 days after the COVID-19-positive case date (1.22, 1.02-1.46). CONCLUSION: In this study of a national cohort of US veterans, we found that the use of an ACEI/ARB in patients with COVID-19 was not associated with increased mortality and other worse outcomes. Future studies should examine underlying pathways and further confirm the relationship of ACEI prescription with sepsis.

Angiotensin-converting enzyme inhibitors versus angiotensin receptor blockers: New-onset diabetes mellitus stratified by statin use.

WHAT IS KNOWN AND OBJECTIVES: Regardless of statin use, which is known to induce hyperglycaemia, comparative studies on the risk of new-onset diabetes mellitus (NODM) with angiotensin-converting enzyme inhibitors (ACEIs) and angiotensin II receptor blockers (ARBs) are needed. This study evaluated the effects of ACEIs and ARBs on NODM in the clinical setting. METHODS: This retrospective cohort study utilized electronic medical record data from Seoul St. Mary's Hospital and Seoul National University Hospital from 2009 to 2012. Patients who were prescribed ACEIs or ARBs for the first time (irrespective of concomitant statin use) were followed up for 5 years. RESULTS AND DISCUSSIONS: A total of 11,703 patients were included, 24.9% (n = 2916) were taking ACEIs and 75.1% (n = 9189) were taking ARBs. Patients on ACEIs had a significantly lower incidence of NODM both with statin use (HR = 0.13, p < 0.001) and without (HR = 0.15, p = 0.009) than patients on ARBs. Age ≥60 years (HR = 1.49, p = 0.010), BMI ≥25 (HR = 1.96, p < 0.010), use of calcium channel blockers (HR = 1.47, p = 0.010), and diuretics (HR = 1.48, p = 0.010) were risk factors for NODM with statin use. WHAT IS NEW AND CONCLUSION: Patients taking ACEIs are less likely to develop NODM than patients taking ARBs, irrespective of statin use. Patients' conditions, including the risk of NODM, should be considered before prescribing ACEIs or ARBs. Future randomized clinical trials are needed to clarify further the relationship between ACEIs and ARBs and their effect on NODM.

ARB might be superior to ACEI for treatment of hypertensive COVID-19 patients.

The administration of ACEI/ARB (angiotensin-converting enzyme inhibitors/Angiotension II receptor blockers) in COVID-19 (coronavirus disease 2019) patients with hypertension exhibits a lower risk of mortality compared with ACEI/ARB non-users. In this context, an important question arises: is ACEI or ARB more suitable for the treatment of hypertensive COVID-19 patients? Taken into consideration the following four rationales, ARB may offer a more significant benefit than ACEI for the short-term treatment of hypertensive COVID-19 patients: 1. ACEI has no inhibition on non-ACE-mediated Ang II production under infection conditions, whereas ARB can function properly regardless of how Ang II is produced; 2. ACEI-induced bradykinin accumulation may instigate severe ARDS while ARB has no effects on kinin metabolism; 3. ARB alleviates viscous sputa production and inflammatory reaction significantly in contrast to ACEI; 4. ARB may attenuate the lung fibrosis induced by mechanical ventilation in severe patients and improve their prognosis significantly compared with ACEI. To examine the advantages of ARB over ACEI on hypertensive COVID-19 patients, retrospective case-control studies comparing the clinical outcomes for COVID-19 patients receiving ARB or ACEI treatment is strikingly needed in order to provide guidance for the clinical application.

Critical timing of ACEi initiation prevents compensatory glomerular hypertrophy in the remaining single kidney.

Increasing evidence suggests that single in kidney states (e.g., kidney transplantation and living donation) progressive glomerulosclerosis limits kidney lifespan. Modeling shows that post-nephrectomy compensatory glomerular volume (GV) increase drives podocyte depletion and hypertrophic stress resulting in proteinuria and glomerulosclerosis, implying that GV increase could serve as a therapeutic target to prevent progression. In this report we examine how Angiotensin Converting Enzyme inhibition (ACEi), started before uninephrectomy can reduce compensatory GV increase in wild-type Fischer344 rats. An unbiased computer-assisted method was used for morphometric analysis. Urine Insulin-like growth factor-1 (IGF-1), the major diver of body and kidney growth, was used as a readout. In long-term (40-week) studies of uni-nephrectomized versus sham-nephrectomized rats a 2.2-fold increase in GV was associated with reduced podocyte density, increased proteinuria and glomerulosclerosis. Compensatory GV increase was largely prevented by ACEi started a week before but not after uni-nephrectomy with no measurable impact on long-term eGFR. Similarly, in short-term (14-day) studies, ACEi started a week before uni-nephrectomy reduced both GV increase and urine IGF-1 excretion. Thus, timing of ACEi in relation to uni-nephrectomy had significant impact on post-nephrectomy "compensatory" glomerular growth and outcomes that could potentially be used to improve kidney transplantation and live kidney donation outcomes.

The angiotensin-converting enzyme inhibitor, captopril, suppressed hepatic stellate cell activation via NF-kappaB or wnt3α/ß-catenin pathway.

Activation of hepatic stellate cells (HSC) is associated with hepatic fibrogenesis, which is one of complications of diabetes mellitus. Captopril possesses potent anti-inflammation, oxidative stress and fibrosis effects. However, the specific molecular mechanism of captopril in high glucose (HG)-induced hepatic stellate cells has not been elucidated. Following the treatment of HG or captopril treatment for rat hepatic stellate cells (HSC-T6), cell activities were detected by Cell Counting Kit-8 (CCK8) assay. Reactive oxygen species (ROS) levels were determined by ROS staining. The expression of inflammation-related proteins (Interleukin (IL)-1ß, IL-6 and IL-8) and fibrosis-related proteins (fibronectin (FN), collagen I, collagen III, collagen IV, matrix metallopeptidase (MMP-2 and MMP-9) were determined by Western blot. Captopril significantly decreased HSC-T6 cell viability induced by HG in a dose-dependent manner, as well as decreased levels of malondialdehyde (MDA), ROS, pro-inflammatory markers and fibrosis-related proteins, while upregulated superoxide dismutase (SOD) activities. We further found that captopril decreased the ratio of p-IκBα/IκBα and the ratio of p-p65/p65. Intriguing, phorbol myristate acetate (PMA) or LiCl was able to significantly reverse the captopril-induced alteration of oxidative stress-, inflammation- and fibrosis-marker levels. In conclusion, in HG-stimulated HSC-T6 cells, captopril displayed a potent ability to inhibit oxidative stress, inflammation and hepatic fibrogenesis via NF-kappaB or wnt3α/ß-catenin. These results demonstrated the mechanism of captopril as well as the role of the NF-kappaB or wnt3α/ß-catenin on HSC-T6 activation induced by HG.

Yuquan pill enhance the effect of Western medicine in treatment diabetic nephropathy: A protocol for systematic review and meta-analysis.

BACKGROUND: Diabetic nephropathy is glomerular sclerosis caused by diabetic microvascular disease, which is one of the most serious complications of diabetes. At present, the traditional treatment of diabetic nephropathy is mainly based on the control of blood pressure, blood sugar, blood lipids, and other basic treatments using angiotensin converting enzyme inhibitor/angiotensin receptor blocker, the clinical reports of relying solely on angiotensin converting enzyme inhibitor/ angiotensin receptor blocker to delay the course of diabetic nephropathy are not optimistic. Yuquan pill (YQP), a classic traditional Chinese medicine prescription, has clinical reports that it can effectively assist in the treatment of diabetic nephropathy with minimal side effects. However, there has been no systematic review of the YQP in the treatment of diabetic nephropathy. This article systematically evaluated the effectiveness and safety of YQP clinical applications. METHODS: The database search include seven databases, including PubMed, Embase, Cochrane Library, Chinese Biomedical Literature Database, Chinese National Knowledge Infrastructure, Chinese Scientific Journal Database, and Wanfang database. The search date was set as a randomized controlled trial from the establishment of the database to April 21, 2021. The main outcome indicators include urinealbumin excretion rate, serum creatinine, urea nitrogen, Total effective rate. The analysis software uses Stata 15. RESULTS: This study will analyze multiple outcome indicators such as clinical efficacy, urinary albumin excretion rate, blood creatinine value, urea nitrogen, and symptom scores. Provides a the latest evidence for YQP in the treatment of diabetic nephropathy (DN). CONCLUSION: The results of this study will provide evidence for the efficacy of YQP in the treatment of DN.

Angiotensin II receptor blocker intake associates with reduced markers of inflammatory activation and decreased mortality in patients with cardiovascular comorbidities and COVID-19 disease.

AIMS: Patients with cardiovascular comorbidities have a significantly increased risk for a critical course of COVID-19. As the SARS-CoV2 virus enters cells via the angiotensin-converting enzyme receptor II (ACE2), drugs which interact with the renin angiotensin aldosterone system (RAAS) were suspected to influence disease severity. METHODS AND RESULTS: We analyzed 1946 consecutive patients with cardiovascular comorbidities or hypertension enrolled in one of the largest European COVID-19 registries, the Lean European Open Survey on SARS-CoV-2 (LEOSS) registry. Here, we show that angiotensin II receptor blocker intake is associated with decreased mortality in patients with COVID-19 [OR 0.75 (95% CI 0,59-0.96; p = 0.013)]. This effect was mainly driven by patients, who presented in an early phase of COVID-19 at baseline [OR 0,64 (95% CI 0,43-0,96; p = 0.029)]. Kaplan-Meier analysis revealed a significantly lower incidence of death in patients on an angiotensin receptor blocker (ARB) (n = 33/318;10,4%) compared to patients using an angiotensin-converting enzyme inhibitor (ACEi) (n = 60/348;17,2%) or patients who received neither an ACE-inhibitor nor an ARB at baseline in the uncomplicated phase (n = 90/466; 19,3%; p<0.034). Patients taking an ARB were significantly less frequently reaching the mortality predicting threshold for leukocytes (p<0.001), neutrophils (p = 0.002) and the inflammatory markers CRP (p = 0.021), procalcitonin (p = 0.001) and IL-6 (p = 0.049). ACE2 expression levels in human lung samples were not altered in patients taking RAAS modulators. CONCLUSION: These data suggest a beneficial effect of ARBs on disease severity in patients with cardiovascular comorbidities and COVID-19, which is linked to dampened systemic inflammatory activity.

Association between Angiotensin-Converting Enzyme Inhibitors and Angiotensin Receptor Blockers and Lung Cancer.

OBJECTIVES: Angiotensin-converting enzyme inhibitors (ACEIs) and angiotensin receptor blockers (ARBs) are the most commonly prescribed antihypertensives, with prior studies identifying a possible association between long-term use and increased rates of lung cancer. This study evaluated this potential association in a large population using propensity matching. METHODS: This was a population-based cohort study in a large healthcare system in three regions of the United States. Pairwise propensity score matching was performed using demographics and comorbidities. All of the adult patients in the healthcare system from January 1, 2000 to April 30, 2018 with at least 1 year of follow-up were included. RESULTS: In total, 3,253,811 patients with a median age of 59 (range 18-103) years were included. The ACEI group had a higher freedom from lung cancer versus controls at 15 years (98.47%, 95% confidence interval [CI] 98.41-98.54) versus 98.26%, (95% CI 98.20-98.33), whereas ARBs had similar rates versus controls at all time points. For patients diagnosed as having lung cancer, median all-cause survival was significantly higher in the ACEI (34.7 months, 95% CI 32.8-36.6) and ARB (30.9 months, 95% CI 28.1-33.8) groups than the control group (20.6 months, 95% CI 20.1-21.1). CONCLUSIONS: This study showed lower rates of lung cancer with ACEI use and no difference in risk with ARBs. In addition, use of these medications was found to be associated with increased survival in those diagnosed as having lung cancer. This study supports the continued use of these medications without concern for increasing the risk of lung cancer.

Association between COVID-19 and angiotensin-converting enzyme inhibitors with the spotlight on zinc: an opinion.

In the setting of the raging COVID-19 pandemic, the search for innovative therapeutics is desperately sought after. As we learn more about the characteristics and metabolic health of patients and as our understanding of COVID-19 pathophysiology and treatment progresses, so is our understanding of medication effects that might increase disease severity. As of late, ACE inhibitors have been under investigation for a potential increase in illness severity due to ACE2 upregulation. Given our knowledge of other nutrient-pharmaceutical interactions, could the ACE inhibitor impact on COVID be due to something else? In this paper, we discuss the possibility that ACE inhibitors might be affecting COVID-19 patients by causing zinc insufficiency.KEY MESSAGESZinc deficiency caused by chronic ACE inhibitor usage may exacerbate the pathogenicity of COVID-19 in susceptible patients.A multi-center study is needed to assess the zinc levels of patients with COVID-19 who are taking ACE inhibitors and other medications that may result in low zinc levels.

Manejo del angiodema inducido por inhibidores de la enzima convertidora de angiotensina con icatibant / Management of angiotensin-converting enzyme inhibitors-related angioedema with icatibant

Objetivo: Evaluar la efectividad de icatibant en el tratamiento del angioedema inducido por IECA (AII), en un centro sin protocolización previa del manejo.Método: Estudio observacional retrospectivo y descriptivo. Se incluyeron pacientes diagnosticados de AII y tratados con icatibant 30 mg entre mayo 2015-diciembre 2017. Las variables de resultado principal y secundaria fueron: tiempo hasta resolución completa y tiempo hasta primera mejoría; respectivamente.Resultados: Cinco pacientes, mediana de edad 76 años (46-81); cuatro mujeres y un varón. Todos caucásicos. Medianas de tiempo hasta resolución completa y hasta primera mejoría: 23 horas (IQR 20,0-25,0) y 3 horas (IQR 3,0-6,0); respectivamente.Conclusiones. El inicio temprano del tratamiento anti-bradicinérgico puede resultar clave para la evolución del cuadro. Para alcanzar la máxima efectividad, se reduzcan las morbilidades asociadas, los ingresos en UCI y el tiempo de estancia hospitalaria, resulta primordial la elaboración de protocolos locales que tengan en cuenta las particularidades de cada centro.

Objetive: To assess the effectiveness of icatibant in the management of angiotensin-converting enzyme inhibitor-induced angioedema (AII) in a hospital without a treatment guidance.Methods: Observational, retrospective and descriptive study. All patients diagnossed with AII and treated with icatibant 30 mg between May 2015-December 2017 were included. The primary and secondary end-points were: time to total resolution and time to first improvement; respectively.Results: Five patients, median age 76 years (46-81). Four women and a man. All of them Caucasian. Median time to total resolution and to first improvement: 23 hours (IQR 20.0-25.0) and 3 hours (IQR 3.0-6.0); respectively.Conclusion: The early start with the anti-bradicinergic therapy may be key to the AII evolution. To achieve the maximum effectiveness and to get reduced the associated morbidity, the ICU admission and the time to discharge, the development of local protocols considering the particularities of each center is highly necessary.
