Population-based discovery and Mendelian randomization analysis identify telmisartan as a candidate medicine for Alzheimer's disease in African Americans. Alzheimers Dement 2023; 19:1876-1887. [PMID: 36331056 PMCID: PMC10156891 DOI: 10.1002/alz.12819] [Citation(s) in RCA: 7] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/01/2022] [Revised: 08/11/2022] [Accepted: 09/02/2022] [Indexed: 11/06/2022]
Abstract
INTRODUCTION African Americans (AAs) and European Americans (EAs) differ in Alzheimer's disease (AD) prevalence, risk factors, and symptomatic presentation and AAs are less likely to enroll in AD clinical trials. METHODS We conducted race-conscious pharmacoepidemiologic studies of 5.62 million older individuals (age ≥60) to investigate the association of telmisartan exposure and AD outcome using Cox analysis, Kaplan-Meier analysis, and log-rank test. We performed Mendelian randomization (MR) analysis of large ethnically diverse genetic data to test likely causal relationships between telmisartan's target and AD. RESULTS We identified that moderate/high telmisartan exposure was significantly associated with a reduced incidence of AD in the AAs compared to low/no telmisartan exposure (hazard ratio [HR] = 0.77, 95% CI: 0.65-0.91, p-value = 0.0022), but not in the non-Hispanic EAs (HR = 0.97, 95% CI: 0.89-1.05, p-value = 0.4110). Sensitivity and sex-/age-stratified patient subgroup analyses identified that telmisartan's medication possession ratio (MPR) and average hypertension daily dosage were significantly associated with a stronger reduction in the incidence of both AD and dementia in AAs. Using MR analysis from large genome-wide association studies (GWAS) (over 2 million individuals) across AD, hypertension, and diabetes, we further identified AA-specific beneficial effects of telmisartan for AD. DISCUSSION Randomized controlled trials with ethnically diverse patient cohorts are warranted to establish causality and therapeutic outcomes of telmisartan and AD. HIGHLIGHTS Telmisartan is associated with lower risk of Alzheimer's disease (AD) in African Americans (AAs). Telmisartan is the only angiotensin II receptor blockers having PPAR-γ agonistic properties with beneficial anti-diabetic and renal function effects, which mitigate AD risk in AAs. Mendelian randomization (MR) analysis demonstrates the specificity of telmisartan's protective mechanism to AAs.

Abstract
Renal proteinuria is associated with promoted renal dysfunction and a shorter survival period in dogs with chronic kidney disease (CKD). Renin angiotensin- aldosterone system inhibitors are primarily used to treat renal proteinuria. In this retrospective, open-label study, we aimed to evaluate the anti-proteinuric and anti-hypertensive effects of telmisartan (angiotensin II receptor blocker) in dogs with proteinuric CKD. A total of 28 dogs with proteinuric CKD were included in the study, all dogs received telmisartan 1 mg/kg q24h, PO. The urine protein-to-creatinine ratio (UPC), urine albumin-to-creatinine ratio (UAC) and systolic blood pressure (SBP) decreased significantly after telmisartan administration (P < 0.05). The median rate of change in UPC, UAC and SBP at Day 120 were - 65.1%, -75.9% and - 9.7%. Ten dogs (36.7%) achieved UPC < 1.0 at Day 120, of which six dogs had UPC < 0.5. A reduction of UPC to ≥50% was achieved in 10 dogs (36%) at Day 45 and 17 dogs (61%) at Day 120. Seventeen dogs (61%) had hypertension at baseline, of which 10 dogs (59%) had SBP < 160 mmHg at Day 120. Two-way repeated measures analysis of variance did not attribute the observed changes in SBP, UPC or UAC to feeding with a renal diet. In conclusion, telmisartan therapy provides anti-proteinuric and anti-hypertensive effects in dogs with proteinuric CKD.

Abstract
The most important result of the revision of the European and Russian guidelines for the management of arterial hypertension (AH) was a special focus on initializing antihypertensive treatment with single-pill combinations (SPCs) in majority patients with AH. Combination of the angiotensin II receptor blocker and thiazide diuretic is one of the possible first line SPCs in the absence of specific clinical conditions according to the new guidelines. In this regard, SPC of telmisartan and hydrochlorothiazide (HCT), worth special noticing in the classes of sartans and thiazide diuretics, since both drugs have a long clinical experience and large body of evidence of antihypertensive efficacy and safety, as well as telmisartan also has a number of superior target-organ protective and metabolic properties distinguishing it from other members of the class. In real clinical practice TANDEM study telmisartan and its SPC with HCT showed high antihypertensive efficacy and good tolerability in patients with all AH grades and with isolated systolic AH and allowed to achieve target blood pressure levels in the most of patients. Long-lasting effect is another essential characteristic of telmisartan, this feature allows to control blood pressure throughout the day, including the morning surge, which is the most “dangerous” in terms of cardiovascular risk. Telmisartan also provide powerful target-organ protection realized at the level of all AH target-organs. Finally, another unique pharmacological property of telmisartan and its combination with HCT is a favourable effect on the carbohydrate and lipid profile, which comprises of increasing tissue sensitivity to insulin, normalizing blood glucose levels, reducing blood total cholesterol, low-density lipoprotein cholesterol and triglycerides and thereby reducing risk of atherosclerosis development and progression. Telmisartan/HCT SPC should be recommended for wide use in hypertensive patients to control blood pressure, protect end-organs, improve prognosis and reduce cardiovascular risk due to its high antihypertensive efficacy, the ability to provide the large target-organ protection and a beneficial metabolic effect.

Abstract
Background: Globally the burden of chronic kidney disease (CKD) is rising, an important cause of death and loss of disability-adjusted life years. Activation of the renin-angiotensin-aldosterone system is involved in its pathogenesis. The aim of the present study was to examine the effects of telmisartan (40 mg/day), an angiotensin receptor blocker (ARB) in Indian patients with CKD in real-life setting. Method: This was a prospective observational study. Fifty-six patients (>18 years) diagnosed with CKD were enrolled into the study. Serum creatinine, 24-h urinary protein, spot urine protein-to-creatinine ratio, glomerular filtration rate (GFR) and blood pressure (BP) were assessed along with safety. Results: A total of 55 patients (96.36% hypertensive; 63.61% diabetic) with mean age of 48.23 years completed the study. At the end of 3 months treatment with telmisartan, 24-h urinary protein, spot urine protein-to-creatinine, serum creatinine and BP significantly reduced (p < .05) by 806.78 mg, 0.95, 0.44 mg/dl and 8.9/4.7 mmHg in the overall population. GFR increased from the baseline value of 52.13 to 65.01 ml/min. Telmisartan was well tolerated and treatment was discontinued in one patient because of hyperkalemia. Conclusion: This study demonstrated that telmisartan effectively and safely reduces proteinuria in chronic kidney disease patients.

Abstract
BACKGROUND Laparoscopic surgery has begun to replace a great number of procedures that were previously practiced using open or conventional techniques. This is due to the minimal invasion, small incisions, and short time recovery. However, it has come to knowledge, that the increase in intra-abdominal pressure due to carbon dioxide pneumoperitoneum during laparoscopic surgery causes cardiovascular, respiratory, endocrine, and renal alterations. OBJECTIVE To evaluate the nephroprotective effect of telmisartan, an angiotensin II AT1 receptor antagonist, on glomerular filtration in laparoscopic surgery. MATERIAL AND METHODS Analytical prospective, randomised, double-blind study was conducted on patients undergoing elective laparoscopic cholecystectomy. They were randomised into 2 groups, with the treatment group receiving a single dose of 40mg telmisartan orally 2hours prior to surgery, and the placebo group. RESULTS There were 20 patients in each group (n=40), with a mean age of 32.65 years in the treatment group. Plasma creatinine did not show any significant change in the different time lapse in which blood samples were taken, but creatinine clearance at the end of surgery (196.415±56.507 vs. 150.1995±75.081; p=0.034), and at 2 h postoperative period (162.105±44.756 vs. 113.235±31.228; p≤0.001) was statistically significant, which supports an increase in renal function in the telmisartan group. CONCLUSION The use of telmisartan, an angiotensin II AT1 receptor antagonist, offers renal protection during laparoscopic surgery.

Abstract
BACKGROUND Blocking the renin-angiotensin system (RAS) with angiotensin receptor blockers or angiotensin-converting enzyme inhibitors protects against renal injury in patients with chronic kidney disease (CKD). The aim of this study was to compare the chronic effects of telmisartan and enalapril on proteinuria, urinary liver-type fatty acid-binding protein (L-FABP) and endothelin (ET)-1 levels in patients with mild CKD. MATERIALS AND METHODS Thirty CKD patients with mild to moderate renal insufficiency (20 men and 10 women; mean age, 37 years; estimated glomerular filtration rate (eGFR) > 60 mL min(-1) and blood pressure > 130/85 mmHg) were included in the study. Patients were randomly assigned to receive telmisartan at 80 mg day(-1) (n = 15) or enalapril at 10 mg day(-1) (n = 15). We measured blood pressure, serum creatinine, eGFR, urinary protein, L-FABP and ET-1 before the start of treatment and 6 and 12 months after the start of treatment. RESULTS The blood pressure reduction rate was similar between the two groups. Urinary protein, L-FABP and ET-1 levels were significantly reduced in both groups 6 and 12 months (P < 0.001) after treatment, but the reduction rates were more pronounced in patients receiving telmisartan than in those receiving enalapril (P < 0.001). Estimated glomerular filtration rate was increased similarly in both groups at 12 months. CONCLUSIONS The study results suggest that telmisartan results in a greater reduction of urinary markers than does enalapril and that this effect occurs by a mechanism independent of blood pressure reduction. It would be needed to investigate whether the differences may be distinct or not the same when other dosages are used.

Abstract
Increasing attention is being devoted to the use of combination therapy with angiotensin-converting enzyme (ACE) inhibitors and angiotensin receptor blockers (ARBs) in order to achieve maximal blockade of the renin-angiotensin system (RAS) in patients at high risk of cardiovascular events. This approach has been adopted in the Ongoing Telmisartan Alone and in Combination with Ramipril Global Endpoint Trial (ONTARGET), which compared the effects of the ARB telmisartan and the ACE inhibitor ramipril, alone and in combination, on cardiovascular mortality and morbidity in high-risk patients with vascular disease or diabetes mellitus and end-organ damage. The results showed that telmisartan was as effective as ramipril for the primary cardiovascular outcome during a 56-month follow-up but was better tolerated. However, dual RAS blockade was not associated with any additional benefits, and the incidence of adverse events was greater with the combination. Based on these findings, optimal cardioprotective strategies in high-risk patients are likely to involve the addition of either telmisartan or ramipril on top of the patient's usual care, but not both. The choice of agent to be used in the long term could be based on other considerations, such as compliance and safety. Both cough and angioedema were higher with ramipril than telmisartan during the 56-month follow-up period in ONTARGET.

Abstract
The present study was conducted to compare the renal and vascular protective effects of telmisartan and amlodipine in untreated hypertensive chronic kidney disease (CKD) patients with moderate renal insufficiency. Thirty hypertensive CKD patients were randomly assigned to receive telmisartan 40 mg (n = 15) or amlodipine 5 mg (n = 15) once daily for 12 months. Changes in blood pressure, serum creatinine, 24-h creatinine clearance (Ccr), proteinuria, brachial-ankle pulse wave velocity (baPWV), intima-media thickness (IMT), plasma interleukin-6 (IL-6), plasma matrix metalloproteinase (MMP)-9 and lipid profiles were monitored in all patients. Before treatment, there were no significant differences in these parameters between the telmisartan and amlodipine groups. Over the 12 month observation period, blood pressure decreased equally in both groups. However, serum creatinine, proteinuria, baPWV, IMT, plasma levels of IL-6 and MMP-9 and total cholesterol decreased and 24-h Ccr increased more strikingly in the telmisartan group than the amlodipine group. These data suggest that telmisartan is more effective than amlodipine for protecting renovascular functions, and potentially for ameliorating atherosclerosis, in hypertensive CKD patients with moderate renal insufficiency.

Abstract
Lowering blood pressure is the most effective treatment method to ensure a reduction in the total risk for cardiovascular morbidity and mortality. The renin-angiotensin system plays an important role in volume homeostasis and blood pressure regulation and is a target for several groups of pharmaceutical agents. Angiotensin II receptor blockers represent the newest class of antihypertensive compounds. They prevent the binding of angiotensin II to the subtype 1 receptor (AT(1)), which is believed to mediate most of the physiological actions relevant to the regulation of blood pressure. Telmisartan, a widely used AT(1) receptor antagonist, is a highly selective compound with high potency, a long duration of action and a tolerability profile similar to placebo. Numerous randomized clinical trials and community-based studies have demonstrated that oral telmisartan and combinations of telmisartan with hydrochlorothiazide are at least as effective in lowering blood pressure as all other hypertensive medications. This has been demonstrated in different populations of adult patients with mild-to-moderate essential hypertension, including patients with coexisting Type 2 diabetes, metabolic syndrome or renal impairment. Several large-scale, long-term, clinical endpoint studies are in progress to assess the beneficial effects of telmisartan on hypertension-related end-organ damage in patients at high risk of renal, cardiac and vascular damage whose blood pressure is well controlled. The most recent data from clinical trials and latest research regarding telmisartan will be reviewed in this article.
