Abstract
Because SARS-COV2 entry into cells is dependent on angiotensin converting enzyme 2 (ACE2) and angiotensin converting enzyme inhibitors (ACEIs) or angiotensin receptor blockers (ARBs) increase ACE2 activity, the safety of ACEI/ARB usage during the coronavirus disease 2019 (COVID-19) pandemic is a controversial topic. To address that issue, we performed a meta-analysis following The Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Searches of the Embase, MEDLINE, PubMed, and Cochrane Library databases identified 16 case-control studies examining the effect of ACEI/ARB on the incidence of COVID-19 and its severity. ACEI/ARB usage was associated with an increased risk of COVID-19 morbidity (odds ratio (OR) 1.20, 95% confidence interval (CI) 1.07-1.33, P=0.001) among the general population but not in a hypertensive population (OR 1.05, 95% CI 0.90-1.21, P=0.553). ACEI/ARB usage was not associated with an increased risk of COVID-19 morbidity (coefficient 1.00, 95% CI 1.00-1.00, P=0.660) when we adjusted for hypertension in the general population. ACEI/ARB usage was also not associated with an increased risk of severe illness (OR 0.90, 95%CI 0.55-1.47, P=0.664) or mortality (OR 1.43, 95%CI 0.97-2.10, P=0.070) in COVID-19 patients. Our meta-analysis revealed that ACEI/ARB usage was not associated with either the increased risk of SARS-COV2 infection or the adverse outcomes in COVID-19 patients.

Effects of antihypertensive medication and high-intensity interval training in hypertensive metabolic syndrome individuals. Scand J Med Sci Sports 2021; 31:1411-1419. [PMID: 33662166 DOI: 10.1111/sms.13949] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/16/2020] [Revised: 02/16/2021] [Accepted: 02/27/2021] [Indexed: 01/12/2023]
Abstract
Pharmacological and non-pharmacological therapies are simultaneously prescribed when treating hypertensive individuals with elevated cardiovascular risk (ie, metabolic syndrome individuals). However, it is unknown if the interactions between antihypertensive medication (AHM) and lifestyle interventions (ie, exercise training) may result in a better ambulatory blood pressure (ABP) control. To test this hypothesis, 36 hypertensive individuals with metabolic syndrome (MetS) under long-term prescription with AHM targeting the renin-angiotensin-aldosterone system (RAAS) were recruited. Before and after 4 months of high-intensity interval training (HIIT), participants completed two trials in a double-blind, randomized order: (a) placebo trial consisting of AHM withdrawal for 3 days and (b) AHM trial where individuals held their habitual dose of AHM. In each trial, 24-h mean arterial pressure (MAP) was monitored and considered the primary study outcome. Secondary outcomes included plasma renin activity (PRA) and aldosterone concentration to confirm withdrawal effects on RAAS, along with the analysis of urine albumin-to-creatinine ratio (UACR) to assess kidney function. The results showed main effects from AHM and HIIT reducing 24-h MAP (-5.7 mmHg, p < 0.001 and -2.3 mmHg, p = 0.007, respectively). However, there was not interaction between AHM and HIIT on 24-h MAP (p = 0.240). There was a main effect of AHM increasing PRA (p < 0.001) but no effect on plasma aldosterone concentration (p = 0.368). HIIT did not significantly improve RAAS hormones or the UACR. In conclusion, AHM and HIIT have independent and additive effects in lowering ABP. These findings support the combination of habitual AHM with exercise training with the goal to reduce ABP in hypertensive MetS individuals.

Abstract
Since December 2019, the coronavirus 2019 (COVID-19) pandemic has rapidly spread and overwhelmed healthcare systems worldwide, urging physicians to understand how to manage this novel infection. Early in the pandemic, more severe forms of COVID-19 have been observed in patients with cardiovascular comorbidities, who are often treated with renin-angiotensin aldosterone system (RAAS)-blockers, such as angiotensin-converting enzyme inhibitors (ACEIs) or angiotensin receptor blockers (ARBs), but whether these are indeed independent risk factors is unknown. The cellular receptor for the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is the membrane-bound angiotensin converting enzyme 2 (ACE2), as for SARS-CoV(-1). Experimental data suggest that expression of ACE2 may be increased by RAAS-blockers, raising concerns that these drugs may facilitate viral cell entry. On the other hand, ACE2 is a key counter-regulator of the RAAS, by degrading angiotensin II into angiotensin (1-7), and may thereby mediate beneficial effects in COVID-19. These considerations have raised concerns about the management of these drugs, and early comments shed vivid controversy among physicians. This review will describe the homeostatic balance between ACE-angiotensin II and ACE2-angiotensin (1-7) and summarize the pathophysiological rationale underlying the debated role of the RAAS and its modulators in the context of the pandemic. In addition, we will review available evidence investigating the impact of RAAS blockers on the course and prognosis of COVID-19 and discuss why retrospective observational studies should be interpreted with caution. These considerations highlight the importance of solid evidence-based data in order to guide physicians in the management of RAAS-interfering drugs in the general population as well as in patients with more or less severe forms of SARS-CoV-2 infection.

J Food Biochem 2021; 45:e13638. [PMID: 33543791 DOI: 10.1111/jfbc.13638] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/01/2020] [Revised: 01/15/2021] [Accepted: 01/18/2021] [Indexed: 01/16/2023]
Abstract
To prepare and identify ACE-inhibitory peptides originated from sesame seed protein, peptides with strong ACE-inhibitory activities were obtained via the optimization of protease and hydrolysis conditions, and these peptides were purified and identified by membrane separation, gel filtration, and liquid chromatography-mass spectrometry. Results showed that the dual-enzyme comprised alcalase and trypsin with the enzyme activity ratio of 3:7 was suitable to produce ACE-inhibitory peptides. The highest ACE-inhibitory activity of 98.10 ± 0.26% was obtained at the following parameters, pH 8.35, E/S ratio of 6,145 U/g, and hydrolysis time of 4.4 hr. ISGAQPSLR and VVISAPSK ranked the first and second ACE-inhibitory activity among 15 identified ACE-inhibitory peptides. Both peptides influenced ACE via binding with the S1 pocket, S2 pocket, and Zn2+ ion. ISGAQPSLR even impacted the S1' pocket. ISGAQPSLR and VVISAPSK acted as a competitive and noncompetitive inhibitor, respectively. ACE-inhibitory peptides derivated from sesame seed protein have potential applications in functional food. PRACTICAL APPLICATIONS: Although sesame seed protein is proven as the precursor of ACE-inhibitory peptide, preparing ACE-inhibitory peptide from sesame seed protein is still suffering from insufficient information on hydrolysis condition and the peptide sequence. Therefore, the performance of the typical protease on preparing ACE-inhibitory peptide from sesame seed protein has been evaluated, the effect of the amino acid composition of sesame seed protein and cleavage specificity of protease on the generation of ACE-inhibitory peptide has been investigated, hydrolysis conditions have been optimized, the peptide sequence has been identified to illuminate the effect of sesame seed protein fraction on the formation of ACE-inhibitory peptide and discuss the structural characteristics. ACE-inhibitory peptides originating from sesame seed protein could apply in functional food. It is promising for dual-enzyme hydrolysis to utilize in preparation of high-value bioactive peptides.

Abstract
BACKGROUND Alport syndrome (AS) is a disease caused by mutations in COL4A3, COL4A4 or COL4A5, the genes that encode distinct chains of type IV collagen. The vast majority of cases presents as an inherited disorder, although de novo mutations are present in around 10% of the cases. METHODS This non-systematic review summarizes recent evidence on AS. We discuss the genetic and pathophysiology of AS, clinical manifestations, histopathology, diagnostic protocols, conventional treatment and prognostic markers of the disease. In addition, we summarize experimental findings with novel therapeutic perspectives for AS. RESULTS The deficient synthesis of collagen heterotrimers throughout the organism leads to impaired basement membranes (BM) in several organs. As a result, the disease manifests in a wide range of conditions, particularly renal, ocular and auricular alterations. Moreover, leiomyomatosis and vascular abnormalities may also be present as atypical presentations. In this framework, diagnosis can be performed based on clinical evaluation, skin or renal biopsy and genetic screening, the latter being the gold standard. There are no formally approved treatments for AS, even though therapeutic options have been described to delay disease progression and increase life expectancy. Novel therapeutic targets under pre-clinical investigation included paricalcitol, sodium-glucose co-transporter-2 inhibitors, bardoxolone methyl, anti-microRNA-21 oligonucleotides, recombinant human pentraxin-2, lysyl oxidase-like-2 blockers, hydroxypropyl-b-cyclodextrin, sodium 4- phenylbutyrate and stem cell therapy. CONCLUSION AS is still a greatly under and misdiagnosed disorder. The pathophysiology is still not fully unnderstand and genetics of the disease have also some gaps. Up to know, there is no specific and effective treatment for AS. Further studies are necessary to establish novel and effective therapeutic protocols.

Abstract
Background Systemic hypertension (SH) is common in dogs and humans with hypercortisolism and can persist after treatment. Objectives To evaluate changes in prevalence of SH and systolic blood pressure (SBP) in dogs with pituitary‐dependent hyperadrenocorticism (PDH) during the first year of trilostane treatment, its relationship with disease control and selected laboratory variables, and their response to antihypertensive treatment. Animals Fifty‐one dogs with PDH treated with trilostane Q12h. Methods Prospective case series study. Dogs were evaluated at diagnosis (T0) and 1, 3, 6, and 12 months (T12). Dogs were classified as nonhypertensive (SBP < 160 mm Hg) or hypertensive (SBP≥160 mm Hg) and subclassified according to target organ damage (TOD) risk. Hypertensive dogs were treated with benazepril and, if control of SH was not achieved, amlodipine was added. Results Prevalence of SH decreased from T0 (36/51) to T12 (17/37; P = .01). Changes in SBP during the study were influenced by the risk of TOD at T0. In severely hypertensive (SBP ≥ 180 mm Hg) dogs, the decrease in SBP was more pronounced whereas in normotensive (SBP < 140 mm Hg) dogs SBP increased slightly (P = .00). Blood pressure was not associated with disease control. Antihypertensive treatment was needed in 31/51 dogs, and in 13/31 dogs additional SH control with amlodipine was required. One third of nonhypertensive dogs at T0 required treatment with benazepril because SH developed during follow‐up. Conclusions and Clinical Importance In dogs with PDH, SBP should be measured at every visit, regardless of disease control or SBP at diagnosis. More than 1 drug may be necessary to manage SH in affected dogs.

Abstract
CONTEXT Amlodipine, a dihydropyridine calcium channel blocker (CCB), is the leading cause of cardiovascular drug-related overdose deaths in the USA. In contrast, angiotensin-II receptor blockers (ARBs) and angiotensin converting enzyme inhibitors (ACEIs) cause minimal toxicity in overdose. ACEIs/ARBs are often combined with dihydropyridines in hypertension treatment. Co-ingested ARBs/ACEIs may significantly contribute to the toxicity of dihydropyridine, but this has not been investigated. OBJECTIVE To investigate the clinical outcomes from dihydropyridine overdoses with ARBs/ACEIs versus dihydropyridine overdoses alone. METHODS This was a retrospective study of patients reported to the New South Wales Poisons Information Centre (NSW PIC) and 3 toxicology units (Jan 2016 to Jun 2019) in Australia. Patients >14 years who took an overdose of dihydropyridines (amlodipine, felodipine, lercanidipine, nifedipine) were included. Concurrent overdoses with non-dihydropyridine CCBs, alpha-blockers and beta-blockers were excluded. Patient demographics, drugs exposure details, serial vital signs, treatments and outcome were collected. RESULTS There were 100 patients. 68 took mixed overdoses of dihydropyridines with ARBs/ACEIs and 32 took single overdoses of dihydropyridines without ARBs/ACEIs. The mixed group had lower median nadir mean arterial pressures (62 vs 75 mmHg, p < 0.001), more frequently had hypotension (OR 4.5, 95%CI: 1.7-11.9) or bradycardia (OR 8.8, 95%CI: 1.1-70). Multivariable analysis indicated the mixed overdoses had an 11.5 mmHg (95%CI: 4.9-18.1) lower minimum systolic blood pressure (SBP) compared with the single group; other factors associated with a lower minimum SBP were higher doses [2.3 mmHg (95%CI: 1.1-3.5) lower per 10 defined daily doses] and younger age [2.2 mmHg (95%CI: 0.3-4.2) higher per decade]. A larger proportion of the mixed ingestion group received intravenous fluids (OR 5.7, 95%CI: 1.8-18.6) and antidotes and/or vasopressors (OR 2.9, 95%CI: 1.004-8.6). CONCLUSION Combined overdoses of dihydropyridines with ARBs/ACEIs caused more significant hypotension and required more haemodynamic support than overdoses of dihydropyridines alone.

Abstract
BACKGROUND Calcium channel blockers (CCBs), beta-receptor blockers (BBs), angiotensin-converting enzyme inhibitors (ACEIs), and angiotensin II receptor blockers (ARBs) have occasionally been reported to cause severe hyponatremia. The aim was to explore the association between CCBs, BBs, ACEIs, and ARBs and hospitalization due to hyponatremia. METHODS Patients hospitalized with a principal diagnosis of hyponatremia (n = 11 213) were compared with matched controls (n = 44 801). Linkage of national population-based registers was used to acquire data. Multivariable logistic regression adjusting for co-medications, diseases, previous hospitalizations, and socioeconomic factors was used to explore the association between hospitalization for severe hyponatremia and the use of different CCBs, BBs, ACEIs, and ARBs. Furthermore, newly initiated (≤90 days) and ongoing use were examined separately. RESULTS Adjusted odds ratios (aORs) (95% confidence interval) for the investigated 4 drug classes ranged from 0.86 (0.81-0.92) for CCBs to 1.15 (1.07-1.23) for ARBs. For newly initiated drugs, aORs spanned from 1.64 (1.35-1.98) for CCBs to 2.24 (1.87-2.68) for ACEIs. In contrast, the corresponding associations for ongoing therapy were not elevated, ranging from 0.81 (0.75-0.86) for CCBs to 1.08 (1.00-1.16) for ARBs. In the CCBs subgroups, aOR for newly initiated vascular CCBs was 1.95 (1.62-2.34) whereas aOR for ongoing treatment was 0.82 (0.77-0.88). CONCLUSIONS For newly initiated CCBs, BBs, ACEIs, and ARBs, the risk of hospitalization due to hyponatremia was moderately elevated. In contrast, there was no evidence that ongoing treatment with investigated antihypertensive drugs increased the risk for hospitalization due to hyponatremia.

Abstract
Background There has been significant controversy regarding the effects of pre‐hospitalization use of renin‐angiotensin system (RAS) inhibitors on the prognosis of hypertensive COVID‐19 patients. Methods and Results We retrospectively assessed 2,297 hospitalized COVID‐19 patients at Tongji Hospital in Wuhan, China, from January 10th to March 30th, 2020; and identified 1,182 patients with known hypertension on pre‐hospitalization therapy. We compared the baseline characteristics and in‐hospital mortality between hypertensive patients taking RAS inhibitors (N=355) versus non‐RAS inhibitors (N=827). Of the 1,182 hypertensive patients (median age 68 years, 49.1% male), 12/355 (3.4%) patients died in the RAS inhibitors group vs. 95/827 (11.5%) patients in the non‐RAS inhibitors group (p<0.0001). Adjusted hazard ratio for mortality was 0.28 (95% CI 0.15‐0.52, p<0.0001) at 45 days in the RAS inhibitors group compared with non‐RAS inhibitors group. Similar findings were observed when patients taking angiotensin receptor blockers (N=289) or angiotensin converting enzyme inhibitors (N=66) were separately compared with non‐RAS inhibitors group. The RAS inhibitors group compared with non‐RAS inhibitors group had lower levels of C‐reactive protein (median 13.5 vs. 24.4 pg/mL; p=0.007) and interleukin‐6 (median 6.0 vs. 8.5 pg/mL; p=0.026) on admission. The protective effect of RAS inhibitors on mortality was confirmed in a meta‐analysis of published data when our data were added to previous studies (odd ratio 0.44, 95% CI 0.29–0.65, p<0.0001). Conclusions In a large single center retrospective analysis we observed a protective effect of pre‐hospitalization use of RAS inhibitors on mortality in hypertensive COVID‐19 patients; which might be associated with reduced inflammatory response.

Abstract
AIMS Angiotensin converting enzyme inhibitors (ACEI) have been recently discussed in connection with the medical treatment of chronic subdural haematoma (CSDH). They may improve the treatment results. The objective of our study was to evaluate the impact of ACEI on the development of CSDH. The first question was to assess the impact of ACEI on postoperative CSDH healing. The second was to assess the impact of ACEI on the development of CSDH as such. PATIENTS AND METHODS The study recruited patients treated surgically for CSDH at our department in the 2013-2018 period. Based on medical records, we retrospectively evaluated the clinical condition of the patients, their history (mainly pharmacological - the use of ACEI) and the course of treatment focussing on the reoccurrence of disease necessitating further therapeutic interventions. For the purpose of evaluating the impact of ACEI on postoperative CSDH healing, the patients were divided into two groups: those using ACEI and those without this medication. The results were compared. We also compared the prevalence of ACEI use in patients with CSDH with the prevalence of ACEI in the comparable population. The difference of the rates allowed us to evaluate the impact of ACEI on the development of CSDH itself. RESULTS Of the 217 patients after surgery for CSDH, 79 continued the use of ACEI; the remaining 138 patients did not use this medication. Patients using ACEI after the surgery experienced a recurrence in 24 (30.4%) cases; patients without ACEI in 37 (26.8%) cases. A negligibly higher number of recurrences was recorded in patients with postoperative use of ACEI, but this difference was not statistically significant (P=0.574). Of a total of 230 patients who underwent surgery for CSDH, 81 were using ACEI chronically (35.2%). In the control group of 100 patients, 38 (38.0%) patients used ACEI. The difference was not statistically significant (P=0.629), so it is not possible to assume that ACEIs influence the development of CSDH as such. CONCLUSION The initial high hopes for a positive ACEI effect on the healing of CSDH are now waived after the publication of several recent studies. According to our present knowledge, the development of CSDH does not appear to be influenced by ACEI use.

Abstract
INTRODUCTION Why do only some of patients who are prescribed angiotensin converting enzyme inhibitors (ACE-I) develop cough? The pathogenesis of ACE-I-induced cough remains controversial and requires further studies. OBJECTIVE We aim to investigate whether asthma is a contributing cause of ACE-I-induced cough. METHODS Patients attending a cardiology clinic between March 2016 and March 2017 who were diagnosed with ACE-I induced cough were included in this study. ACE-I-induced cough was defined as cough which developed within 4 weeks after initiation of ACE-I therapy and which improved within 4 weeks after discontinuation of the ACE-I. Patients who had received ACE-I treatment for at least 6 months without side effects were included in the study as a control group. Face-to-face questionnaires, pulmonary function tests (PFT) and skin prick tests were applied to all the patients. If there was discordance between asthma history and PFT results, a methacholine bronchial provocation test (BPT) was performed. RESULTS A total of 43 patients with ACE-I induce cough were compared with 50 controls. Bronchial hyperreactivity (BHR), rhinitis, atopy and family history of asthma were more frequent in patients with ACE-I induced cough (P < .001). Patients with ACE-I-induced cough had significantly higher incidence of diagnosed asthma [OR = 8.28 (95%CI: 3.26-21.03) P < .001]. CONCLUSIONS Asthma and an atopic background constitute a substantial risk factor for ACE-I induced cough. The presence of underlying asthma should be investigated in patients diagnosed with ACE inhibitor induced cough. However, the fact that most asthma patients tolerate ACE-I therapy, indicates that other cofactors are likely involved.

Abstract
Introduction The renin-angiotensin-aldosterone system (RAAS) is an important target in the treatment of hypertension. Angiotensin-converting enzyme (ACE) inhibitors block the conversion of angiotensin I to angiotensin II. ACE inhibitors not only treat hypertension but also decrease morbidity and mortality in heart failure patients and in patients with acute myocardial infarction. The discontinuation of ACE inhibitors before the surgery is still controversial. To assess the current magnitude of the problem in our population, we aimed to conduct this study, which evaluated the frequency of intraoperative hypotension after the induction of anesthesia in controlled hypertensive patients with preoperative ACE inhibitors. Material and methods This descriptive case series study was conducted at a tertiary hospital in a developing country after approval from the Ethics Review Committee. A total of 115 adult patients, from 16 to 60 years of age, who have undergone elective surgery, have controlled hypertension on the desired drugs for at least six months, have no history of any cardiac event, and have taken the drug on the morning of the surgery, were included in the study after written consent. The demographic data of the patients were entered into the proforma. Preoperative systolic, diastolic, and mean arterial pressure were recorded by the researcher or an assignee in the preoperative holding area. The patients were followed in the recovery room by the team conducting the study until 10 minutes after the arrival of the patient in the recovery room. All statistical analyses were performed using Statistical Packages for the Social Sciences version 19 (SPSS Inc., Chicago, IL). p-value ≤0.05 was considered significant. Results Of the 115 patients, 56 (48.7%) patients were in the age group between 51 and 60 years of age; 38 patients were between the ages of 41 and 50 years and only 21 patients were 40 years or less. On gender, 68 patients were female and 47 were male. According to body mass index (BMI), the majority of the patients were in the overweight group, amounting to 53 (46%), and 86 (74.78%) patients were known diabetics. Overall, 77 (66.96%) of the patients developed intraoperative hypotension with 41 (35.65%) patients requiring the use of vasopressors in order to correct the hypotension. No statistically significant difference was found between demographic and clinical variables. Conclusion Intraoperative hypotension is more frequent in patients with controlled hypertension on ACE inhibitors although more studies need to be conducted on a larger population in order to determine a more definitive result.

Abstract
Membranous nephropathy can be primary or secondary. Although common causes of secondary MN are malignancy and lupus, hypothyroidism was rarely reported. Providers should check thyroid function tests in patients with unexplained nephrotic proteinuria.

Abstract
PURPOSE Commonly prescribed medications among patients with comorbid diabetes mellitus and hypertension include ARBs and ACEIs. However, these medications are associated with suboptimal adherence leading to inadequately controlled blood pressure. Unlike traditional single estimates of proportion of days covered (PDC), group-based trajectory modeling (GBTM) can graphically display the dynamic nature of adherence. The objective of this study was to evaluate adherence using GBTMs among patients prescribed ACEI/ARBs and identify predictors associated with each adherence trajectory. PATIENTS AND METHODS Patients with an ACEI/ARBs prescription were identified between July 2017 and December 2017 using a Medicare Advantage dataset. PDC was used to measure monthly patient adherence during the one-year follow-up period. The monthly PDC was added to a logistic group-based trajectory model to provide distinct patterns of adherence. Further, a multinomial logistic regression was conducted to determine predictors of each identified adherence trajectory. Predictors included various socio-demographic and clinical patient characteristics. RESULTS A total of 22,774 patients were included in the analysis and categorized into 4 distinct adherence trajectories: rapid decline (12.6%); adherent (58.5%); gaps in adherence (12.2%), and gradual decline (16.6%). Significant predictors associated with all lower adherence trajectories included 90 days refill, >2 number of other medications, ≥1 hospitalizations, and prevalent users. Significant predictors associated with the rapid decline trajectory included male sex, comorbidities, and increased CMS risk score. Further, significant predictors associated with the gaps in adherence trajectory included increasing age, and comorbidities. Lastly, significant predictors associated with the gradual decline trajectory included increasing age, no health plan subsidy, comorbidities, and increasing CMS risk score. CONCLUSION Identifying various patient characteristics associated with non-adherent trajectories can guide the development of tailored interventions to enhance adherence to ACEI/ARBs.

Abstract
BACKGROUND Several drugs are used for treating IgA nephropathy (IgAN). We carried out a network meta-analysis evaluating these drugs. METHODS Electronic databases were searched for appropriate randomized clinical trials carried out in patients with IgAN. The primary outcome was proteinuria remission rates and there were several other secondary outcome measures. The risk of bias was assessed. Mixed treatment comparison estimates were modelled from direct and indirect comparison estimates. Grading of the evidence for key comparisons was carried out. RESULTS Fifty-seven clinical trials were included in the systematic review and 51 in the metaanalysis. Polyunsaturated fatty acids, corticosteroids/angiotensin receptor blockers (ARB), ARB, angiotensin converting enzyme inhibitors (ACEI), ARB/ACEI, corticosteroids/ACEI and hypolipidemics/ ARB were observed with significantly higher rates of proteinuria remission than the standard of care. Several benefits were observed with other drugs on the secondary outcome measures. A very low grade was observed for the interventions. CONCLUSION We observed a few interventions to perform better in the management of IgAN. The results of this study will aid in further evaluation of such drugs that may assist in saving the resources and time. However, the readers should interpret the findings with great caution as the results might change with the advent of future head-to-head clinical trials.

Abstract
A 13-year-old male Western lowland gorilla presented acutely with a precipitous decline in health status from liver disease. Through diagnostic assessment, including serum chemistries and advanced imaging, it was diagnosed with probable hepatotoxicity resulting from its prescribed medication, enalapril. As one of several angiotensin converting enzyme inhibitors (ACE-I) available to zoo veterinarians, enalapril had been administered for treatment of mild ventricular hypertrophy diagnosed during routine examination 2.5 years prior to the presentation. The gorilla made a complete recovery with discontinuation of this medication, and provision of hepatoprotectants. Hepatotoxicity has been documented in humans receiving this product as an adverse drug reaction and is considered both rare and unpredictable in occurrence. In this event, an association was suspected with indulgent consumption of mulberry browse (Morus sp.) offered as nutritional enrichment immediately prior to clinical presentation and had potential impact on hepatic cytochrome P450 metabolism of the enalapril. Although ACE-I are important medications in this taxon due to its predisposition to cardiac disease, this event underscores the need for vigilance on the part of veterinarians and managers whenever pharmaceuticals are administered. Most drugs are modeled in a limited number of species but utilized in a wide variety, and unintended results are possible.

Abstract
OBJECTIVE To assess the patterns of angiotensin converting enzyme inhibitors and angiotensin receptor blockers (ACE-I/ARB) discontinuation in the setting of chronic kidney disease (CKD) progression in real-world clinical practice. PATIENTS AND METHODS We identified incident ACE-I/ARB users with a baseline estimated glomerular filtration rate (eGFR) ≥15 mL/min/1.73 m2 and without end-stage renal disease in the Geisinger Health System between January 1, 2004, and December 31, 2015. We investigated the associations of CKD stage, hospitalizations with and without acute kidney injury (AKI), serum potassium, bicarbonate level, thiazide, and loop diuretic use with ACE-I/ARB discontinuation. RESULTS Among the 53,912 ACE-I/ARB users, the mean age was 59.9 years, and 50.6% were female. More than half of users discontinued ACE-I/ARB within 5 years of therapy initiation. The risk of ACE-I/ARB discontinuation increased with more advanced CKD stage. For example, patients who initiated ACE-I/ARB with CKD stage G4 (eGFR: 15-29 mL/min/1.73 m2) were 2.09-fold (95% CI, 1.87-2.34) more likely to discontinue therapy than those with eGFR ≥ 90 mL/min/1.73 m2. Potassium level greater than 5.3 mEq/L, systolic blood pressure ≤ 90 mm Hg, bicarbonate level < 22 mmol/L, and intervening hospitalization-particularly AKI-related-were also strong risk factors for ACE-I/ARB discontinuation. Thiazide diuretic use was associated with lower risk, whereas loop diuretic use was associated with higher risk of discontinuation. CONCLUSION In a real-world cohort, discontinuation of ACE-I/ARB was common, particularly in patients with lower eGFR. Hyperkalemia, hypotension, low bicarbonate level, and hospitalization (AKI-related, in particular) were associated with a higher risk of ACE-I/ARB discontinuation. Additional studies are needed to evaluate the risk-benefit balance of discontinuing ACE-I/ARB in the setting of CKD progression.

Abstract
Halophila stipulacea is a well-known invasive marine sea grass in the Mediterranean Sea. Having been introduced into the Mediterranean Sea via the Suez Channel, it is considered a Lessepsian migrant. Although, unlike other invasive marine seaweeds, it has not demonstrated serious negative impacts on indigenous species, it does have remarkable invasive properties. The present in-silico study reveals the biotechnological features of H. stipulacea by showing bioactive peptides from its rubisc/o protein. These are features such as antioxidant and hypolipideamic activities, dipeptidyl peptidase-IV and angiotensin converting enzyme inhibitions. The reported data open up new applications for such bioactive peptides in the field of pharmacy, medicine and also the food industry.

Abstract
Total-body irradiation causes acute and delayed toxicity to hematopoietic, pulmonary, cardiac, gastrointestinal, renal, and other organ systems. Angiotensin-converting enzyme inhibitors mitigate many of the delayed injuries to these systems. The purpose of this study was to define echocardiographic features in rats at two times after irradiation, the first before lethal radiation pneumonitis (50 d) and the second after recovery from pneumonitis but before lethal radiation nephropathy (100 d), and to determine the actions of the angiotensin-converting enzyme inhibitor lisinopril. Four groups of female WAG/RijCmcr rats at 11-12 wk of age were studied: nonirradiated, nonirradiated plus lisinopril, 13-Gy partial-body irradiation sparing one hind leg (leg-out partial-body irradiation), and 13-Gy leg-out partial-body irradiation plus lisinopril. Lisinopril was started 7 d after radiation. Echocardiograms were obtained at 50 and 100 d, and cardiac histology was assessed after 100 d. Irradiation without lisinopril demonstrated echocardiographic transient pulmonary hypertension by 50 d which was largely resolved by 100 d in survivors. Irradiated rats given lisinopril showed no increase in pulmonary artery pressures at 50 d but exhibited left ventricular remodeling. By 100 d these rats showed some signs of pulmonary hypertension. Lisinopril alone had no impact on echocardiographic end points at either time point in nonirradiated rats. Mild increases in mast cells and fibrosis in the heart were observed after 100 d following 13-Gy leg-out partial-body irradiation. These data demonstrate irradiation-induced pulmonary hypertension which was reversed in survivors of pneumonitis. Lisinopril modified cardiovascular remodeling to enhance survival in this model from 41% to 86% (p = 0.0013).

Abstract
UNLABELLED ABSTRACTBackground:Both elevated blood pressure and/or depression increase the risk of cardiovascular disease and mortality. This study in treated elderly hypertensive patients explored the incidence of depression, its association (pre-existing and incident) with mortality and predictors of incident depression. METHODS Data from 6,083 hypertensive patients aged ≥65 years enrolled in the Second Australian National Blood Pressure study were used. Participants were followed for a median of 10.8 years (including 4.1 years in-trial) and classified into: "no depression," "pre-existing" and "incident" depression groups based on either being "diagnosed with depressive disorders" and/or "treated with an anti-depressant drug" at baseline or during in-trial period. Further, we redefined "depression" restricted to presence of both conditions for sensitivity analyses. For the current study, end-points were all-cause and any cardiovascular mortality. RESULTS 313 (5%) participants had pre-existing depression and a further 916 (15%) participants developed depression during the trial period (incidence 4% per annum). Increased (hazard-ratio, 95% confidence-interval) all-cause mortality was observed among those with either pre-existing (1.23, 1.01-1.50; p = 0.03) or incident (1.26, 1.12-1.41; p < 0.001) depression compared to those without. For cardiovascular mortality, a 24% increased risk (1.24, 1.05-1.47; p = 0.01) was observed among those with incident depression. The sensitivity analyses, using the restricted depression definition showed similar associations. Incident depression was associated with being female, aged ≥75 years, being an active smoker at study entry, and developing new diabetes during the study period. CONCLUSIONS This elderly cohort had a high incidence of depression irrespective of their randomised antihypertensive regimen. Both pre-existing and incident depression were associated with increased mortality.

Abstract
Although renin-angiotensin-aldosterone system (RAAS) blocking agents decrease albuminuria in short-term studies, there is no evidence confirming their long-term efficacy in sickle cell disease (SCD). In a single-centre, retrospective study, we evaluated the long-term effect of RAAS blocking agents on proteinuria and declining estimated glomerular filtration rates (eGFR). Eighty-six patients on RAAS blocking agents for proteinuria, followed for a median of 2·28 years, were compared with 68 patients with proteinuria followed for 2·24 years who were not receiving such treatment. The log odds of proteinuria decreased over time in patients on RAAS blocking agents (β: -0·23, P = 0·03) and in the non-treatment group (β: -0·54, P < 0·0001), but was not statistically different between both groups (β: 0·31, P = 0·063). The eGFR declined over time in patients on RAAS blocking agents (β: -2·78, P < 0·0001) and in those not on such treatment (β: -4·7, P < 0·0001), and was statistically different between both groups (β: 1·9, P = 0·0002). Baseline eGFR was associated with mortality (Hazard rato: 0·97, P < 0·0001), but RAAS blocking agents had no significant effect on mortality. These data suggest that RAAS blockade may slow the loss of kidney function in SCD.

Abstract
Once renal transplant recipients are stabilized and require less frequent follow-up with their transplant team, health care providers outside of the transplant setting play an integral role in patients' ongoing medical care. Given renal transplant recipients' inherent complexity, these health care providers often seek consult regarding decisions that may affect transplant-related medications or outcomes. In this review, we discuss answers to 10 of the questions commonly posed to our renal transplant team by other health care providers.
