Thinking Three-Dimensionally: A Self- and Externally-Controlled Approach to Screening for Drug-Drug-Drug Interactions Among High-Risk Populations.

The global rise in polypharmacy has increased both the necessity and complexity of drug-drug interaction (DDI) assessments, given the growing potential for interactions involving more than two drugs. Leveraging large-scale healthcare claims data, we piloted a semi-automated, high-throughput case-crossover-based approach for drug-drug-drug interaction (3DI) screening. Cases were direct-acting oral anticoagulant (DOAC) users with either a major bleeding event during ongoing dispensings for potentially interacting, enzyme-inhibiting antihypertensive drugs (AHDs) (Study 1), or a thromboembolic event during ongoing dispensings for potentially interacting, enzyme-inducing antiseizure medications (ASMs) (Study 2). 3DI detection was based on screening for additional drug exposures that served as acute outcome triggers. To mitigate direct effects and confounding by concomitant drugs, self-controlled estimates were adjusted using negative cases (external "control" DOAC users with the same outcomes but co-dispensings for non-interacting AHDs or ASMs). Signal thresholds were set based on P-values and false discovery rate q-values to address multiple comparisons. Study 1: 285 drugs were examined among 3,306 episodes. Self-controlled assessments with q-value thresholds yielded 9 3DI signals (cases) and 40 DDI signals (negative cases). External adjustment generated 10 3DI signals from the P-value threshold and no signals from the q-value threshold. Study 2: 126 drugs were examined among 604 episodes. Assessments with P-value thresholds yielded 3 3DI and 26 DDI signals following self-control, as well as 4 3DI signals following adjustment. No 3DI signals met the q-value threshold. The presented self- and externally-controlled approach aimed to advance paradigms for real-world higher order drug interaction screening among high-susceptibility populations with pre-existent DDI risk.

Acute quadruple extremity compartment syndrome due to angio-oedema after polypharmacy overdose including olmesartan medoxomil, telmisartan and vildagliptin.

This case report describes a rare manifestation of acute compartment syndrome (ACS) involving all four extremities, precipitated by angio-oedema in a middle-aged woman who consumed an overdose of multiple medications: nifedipine, azelnidipine, amlodipine besylate, olmesartan medoxomil, telmisartan, esaxerenone and vildagliptin. She presented with haemodynamic instability, necessitating intubation. Despite stabilising haemodynamic parameters within 24 hours, she manifested escalating extremity oedema. At 52 hours after ingestion, mottled skin was observed, along with necrotic alterations in the swollen hands and compartment pressures exceeding 30 mm Hg in all extremities. ACS was diagnosed, leading to fasciotomies. The aetiology is postulated to be drug-induced angio-oedema, possibly intensified by the concurrent overdose of olmesartan medoxomil, telmisartan and vildagliptin, each of which has a risk of angio-oedema even at standard dosages. This scenario is a very rare case caused by drug-induced angio-oedema, which underscores the importance of vigilant monitoring to detect ACS in patients with progressing limb oedema.

Efficacy and safety of a single-pill versus free combination of perindopril/indapamide/amlodipine: a multicenter, randomized, double-blind study in Chinese patients with hypertension.

BACKGROUND: In China, the prevalence of hypertension is high and the use of combination antihypertensive therapy is low, which contributes to inadequate blood pressure (BP) control. The availability of simplified treatments combining complementary BP-lowering agents may help more patients achieve their goals. METHODS: This Phase III, multicenter, randomized, double-blind, noninferiority study included Chinese adults with mild-to-moderate hypertension. Following a 1-month run-in on perindopril/indapamide bi-therapy, patients with uncontrolled systolic/diastolic BP (≥140/90 mmHg) were randomized to perindopril 5 mg/indapamide 1.25 mg/amlodipine 5 mg (Per/Ind/Aml) single-pill combination (SPC) or perindopril 4 mg/indapamide 1.25 mg plus amlodipine 5 mg (Per/Ind + Aml) for 6 months. Uptitration was permitted from month 2 onwards. The primary efficacy objective was the noninferiority of Per/Ind/Aml in lowering office systolic BP at 2 months. The secondary objectives included the effectiveness of SPC on diastolic BP, uptitration efficacy, and office BP control (systolic/diastolic <140/90 mmHg). A subgroup of patients participated in 24-h ambulatory BP monitoring (ABPM). RESULTS: A total of 532 patients were randomized: Per/Ind/Aml ( n  = 262) and Per/Ind + Aml ( n  = 269). Overall, the mean (±SD) age was 55.7 ±â€Š8.8 years, 60.7% were male, and the mean office systolic/diastolic BP at baseline on Per/Ind was 150.4/97.2 mmHg. Systolic BP decreased in both groups at 2 months from baseline: -14.99 ±â€Š14.46 mmHg Per/Ind/Aml versus -14.49 ±â€Š12.87 mmHg Per/Ind +Aml. A predefined noninferiority margin of 4 mmHg was observed ( P  < 0.001). The effectiveness of the Per/Ind/Aml SPC was also demonstrated for all secondary endpoints. ABPM demonstrated sustained BP control over 24 h. Both treatments were well tolerated. CONCLUSIONS: Per/Ind/Aml is an effective substitute for Per/Ind + Aml, providing at least equivalent BP control over 24 h in a single pill, with comparable safety.

Effects of hypertension and use of antihypertensive drugs in pregnancy on the risks of childhood cancers in Taiwan.

BACKGROUND: Childhood cancers are associated with high mortality and morbidity, and some maternal prescription drug use during pregnancy has been implicated in cancer risk. There are few studies on the effects of hypertension, preeclampsia, and the use of antihypertensives in pregnancy on children's cancer risks. OBJECTIVE: This population-based cohort study analyzed the relationship between hypertension, preeclampsia, and antihypertensives taken during pregnancy and the risks of childhood cancers in the offspring. METHODS: Data on all children born in Taiwan between 2004 and 2015 (N = 2,294,292) were obtained from the Maternal and Child Health Database. This registry was linked with the National Health Insurance Database and Cancer Registry to get the records of maternal use of diuretics or other antihypertensives in pregnancy and records of children with cancer diagnosed before 13 years. We used Cox proportional hazard modeling to estimate the influence of maternal health conditions and antihypertensive drug exposure on the risks of developing childhood cancers. RESULTS: Offspring of mothers with hypertension (chronic or gestational) had a higher risk of acute lymphocytic lymphoma [hazard ratio (HR) = 1.87, 95% Confidence Interval (CI) 1.32 - 2.65] and non-Hodgkin's lymphoma (HR = 1.96, 95% CI 1.34 - 2.86). We estimated only a weak increased cancer risk in children whose mothers used diuretics (HR = 1.16, 95% CI 0.77 - 1.74) or used antihypertensives other than diuretics (HR = 1.15, 95% CI 0.86 - 1.54) before birth. CONCLUSIONS: In this cohort study, children whose mothers had chronic and gestational hypertension had an increased risk of developing childhood cancer.

[Drug therapy for arterial hypertension and atrial fibrillation in frail patients : Are there any new insights and recommendations?] / Arzneimitteltherapie von arterieller Hypertonie und Vorhofflimmern bei gebrechlichen Patienten : Gibt es neue Erkenntnisse und Empfehlungen?

The frail and elderly are considered to be at particular risk of suffering an adverse drug reaction. Empirical studies confirm the increased rate of adverse drug reactions. Whether frailty per se impairs drug metabolism or the underlying organ ageing processes and multimorbidity cannot be answered with certainty based on current data. Cardiovascular diseases exhibit a considerable interdependence with frailty. For example, there is a disproportionate syndromal interdependence between heart failure and frailty, and the typical ageing processes of the sinus node can be interpreted as heartbeat frailty. Multimorbidity in the elderly often includes a cluster of chronic cardiovascular diseases, often leading to the use of several cardiovascular medications as required. More recent definitions of polypharmacy assess the appropriateness of drugs rather than their number. The Fit-fOR-The-Aged (FORTA) list, the PRISCUS 2.0 list and the "Cochrane Library Special Collection on deprescribing", for example, offer a practice-oriented assessment aid. In the treatment of arterial hypertension, the target values for older people have also been set ever lower in recent years. In the case of frail elderly people, on the other hand, the guidelines do not specify a strict blood pressure target corridor; tolerability is the crucial factor here. When initiating antihypertensive therapy in frail individuals, one can consider monotherapy-in a departure from the standard case of dual combination therapy. The OPTIMISE study showed that discontinuation of one blood pressure medication did not lead to better tolerability of the drug therapy. Current studies come to differing conclusions regarding the risk-benefit assessment of new oral anticoagulants compared to vitamin K antagonists in the anticoagulation of frail elderly people with atrial fibrillation. Shared decision-making, which could improve adherence particularly in older people, is recommended.

Development of a machine learning-based model for predicting individual responses to antihypertensive treatments.

BACKGROUND AND AIMS: Personalized antihypertensive drug selection is essential for optimizing hypertension management. The study aimed to develop a machine learning (ML) model to predict individual blood pressure (BP) responses to different antihypertensive medications. METHODS AND RESULTS: We used data from a pragmatic, cluster-randomized trial on hypertension management in China. Each patient's multiple visit records were included, and two consecutive visits were paired as the index and subsequent visits. The least absolute shrinkage and selection operator method was used to select index visit variables for predicting subsequent BP. The dataset was randomly divided into training and test sets in a 7:3 ratio. Model performance was evaluated using mean absolute error (MAE) and R-square in the test set. A total of 19,013 hypertension management visit records (6282 patients) were included. The mean age of the study population was 63.9 years, and 2657 (42.3%) were females. A total of 12 phenotypical features (age, sex, smoking within seven days, body mass index, waist circumference, index visit systolic BP, diastolic BP, heart rate, comorbidities of diabetes, dyslipidemia, coronary heart disease, and stroke), together with currently taking any prescribed antihypertensive medication regimens and visits time interval were selected to build the model. The Extreme Gradient Boost model performed best among all candidate algorithms, with an MAE of 8.57 mmHg and an R2 = 0.28 in the test set. CONCLUSION: The ML techniques exhibit significant potential for predicting individual responses to antihypertensive treatments, thereby aiding clinicians in achieving optimal BP control safely and efficiently.

Onco-Hypertension: A Continuously Developing Field between Cancer and Hypertension.

The prognosis of cancer patients has greatly improved in the last years, owing to the development of novel chemotherapeutic agents. However, this progress comes with an increasing occurrence of cardiovascular adverse reactions. A serious side effect is arterial hypertension (HT), which is the most frequent comorbidity encountered in cancer patients, influencing the outcomes in cancer survivors. Even though secondary HT related to specific chemotherapeutic agents, such as vascular endothelial growth factor inhibitors, is usually mild and reversible, in rare instances it can be severe, leading to discontinuation of chemotherapy. In addition, HT per se has been studied as a potential risk factor for cancer development. The relationship is even more complex than previously thought, as concerning evidence recently highlighted the potential oncogenic effects of antihypertensive drugs, particularly thiazide diuretics, which may increase the risk of skin cancer. As a result, in light of the similar risk factors and overlapping pathophysiological mechanisms between HT and cancer, a promising concept of onco-hypertension has emerged, aiming to improve the understanding of the complicated interplay between these two pathologies and maintain a balance between the efficacy and risks of both antihypertensive drugs and chemotherapy agents.

Effect of epoprostenol-induced thrombocytopaenia on lung transplantation for pulmonary arterial hypertension.

OBJECTIVES: Preoperative intravenous epoprostenol therapy can cause thrombocytopaenia, which may increase the risk of perioperative bleeding during lung transplantation. This study aimed to determine whether lung transplantation can be safely performed in patients with epoprostenol-induced thrombocytopaenia. METHODS: From June 2008 to July 2022, we performed 37 lung transplants in patients with pulmonary arterial hypertension (PAH), including idiopathic PAH (n = 26), congenital heart disease-associated PAH (n = 7), pulmonary veno-occlusive disease (n = 3) and peripheral pulmonary artery stenosis (n = 1) at our institution. Of these, 26 patients received intravenous epoprostenol therapy (EPO group), whereas 11 patients were treated with no epoprostenol (no-EPO group). We retrospectively analysed the preoperative and postoperative platelet counts and post-transplant outcomes in each group. RESULTS: Preoperative platelet counts were relatively lower in the EPO group than in the no-EPO group (median EPO: 127 000 vs no-EPO: 176 000/µl). However, blood loss during surgery was similar between the 2 groups (EPO: 2473 ml vs no-EPO: 2615 ml). The platelet counts significantly increased over 1 month after surgery, and both groups showed similar platelet counts (EPO: 298 000 vs no-EPO: 284 000/µl). In-hospital mortality (EPO: 3.9% vs no-EPO: 18.2%) and the 3-year survival rate (EPO: 91.4% vs no-EPO: 80.8%) were similar between the 2 groups. CONCLUSIONS: Patients with PAH treated with intravenous epoprostenol showed relatively lower platelet counts, which improved after lung transplantation with good post-transplant outcomes.

Updates in the management of cancer therapy-related hypertension.

PURPOSE OF REVIEW: To provide a comprehensive review of hypertension among patients with cancer. Several cancer therapies cause hypertension which has resulted in a growing and vulnerable population of patients with difficult to control hypertension which has significant downstream effects. RECENT FINDINGS: Hypertension affects up to 50% of cancer patients and higher comorbidity when compared to the general population. Many anticancer therapies can cause hypertension through their treatment effect. Antihypertensive treatment is crucial given cardiovascular mortality is a leading cause of death among cancer patients. It is already known that hypertension is poorly controlled in the general population, and there are additional challenges in management among patients with cancer. Patients with cancer suffer from multimorbidity, are on multiple medications creating concern for drug interactions, and often have blood pressure lability, which can worsen clinical inertia among patients and their providers. It is crucial to effectively treat hypertension in cancer patients to mitigate downstream adverse cardiovascular events. SUMMARY: In recent years, there have been significant changes in management guidelines of hypertension and simultaneously as influx of new cancer therapeutics. We provide an update on hypertension treatment among patients with cancer on different chemotherapeutic agents.

Hypertension treatment for patients receiving ibrutinib: a multicenter retrospective study.

ABSTRACT: Although Bruton tyrosine kinase inhibitors (BTKis) are generally well tolerated and less toxic than chemotherapy alternatives used to treat lymphoid malignancies, BTKis like ibrutinib have the potential to cause new or worsening hypertension (HTN). Little is known about the optimal treatment of BTKi-associated HTN. Randomly selected patients with lymphoid malignancies on a BTKi and antihypertensive drug(s) and with at least 3 months of follow-up data were sorted into 2 groups: those diagnosed with HTN before BTKi initiation (prior-HTN), and those diagnosed with HTN after BTKi initiation (de novo HTN). Generalized estimating equations assessed associations between time varying mean arterial pressures (MAPs) and individual anti-HTN drug categories. Of 196 patients included in the study, 118 had prior-HTN, and 78 developed de novo HTN. Statistically significant mean MAP reductions were observed in patients with prior-HTN who took ß blockers (BBs) with hydrochlorothiazide (HCTZ), (-5.05 mmHg; 95% confidence interval [CI], 10.0 to -0.0596; P = .047), and patients diagnosed with de novo HTN who took either an angiotensin converting enzyme inhibitor (ACEi) or angiotensin receptor blocker (ARB) with HCTZ (-5.47 mmHg; 95% CI, 10.9 to -0.001; P = .05). These regimens also correlated with the greatest percentages of normotensive MAPs. Treatment of HTN in patients taking a BTKi is challenging and may require multiple antihypertensives. Patients with prior-HTN appear to benefit from combination regimens with BBs and HCTZ, whereas patients with de novo HTN appear to benefit from ACEi/ARBs with HCTZ. These results should be confirmed in prospective studies.

Efficacy of decentralised home-based antihypertensive treatment in older adults with multimorbidity and polypharmacy (ATEMPT): an open-label randomised controlled pilot trial.

BACKGROUND: Older patients with multimorbidity and polypharmacy have been under-represented in clinical trials. We aimed to assess the effect of different intensities of antihypertensive treatment on changes in blood pressure, major safety outcomes, and patient-reported outcomes in this population. METHODS: ATEMPT was a decentralised, two-armed, parallel-group, open-label randomised controlled pilot trial conducted in the Thames Valley area, South East England. Individuals aged 65 years or older with multimorbidity (three or more chronic conditions) or polypharmacy (five or more types of medications) and a systolic blood pressure of 115-165 mm Hg were eligible for inclusion. Participants were identified through a search of national hospital discharge databases, identification of patients registered with an online pharmacy, and via targeted advertising on social media platforms. Participants were randomly assigned to receive up to two more classes versus up to two fewer classes of antihypertensive medications. Apart from routine home visits for conducting the baseline assessment, all communication, monitoring, and management of participants by the trial team was conducted remotely. The primary outcome was change in home-measured blood pressure. FINDINGS: Between Dec 15, 2020, and Aug 31, 2022, 230 participants were randomly assigned (n=126 to more vs n=104 to fewer antihypertensive medications). The frequency of serious adverse events was similar across both groups; no cardiovascular events occurred in the more antihypertensive drugs group, compared with six in the fewer antihypertensive drugs group, of which two were fatal. Over a 13-month follow-up period, the mean systolic blood pressure in the group allocated to receive more antihypertensive medications decreased from 134·5 mm Hg (SD 10·7) at baseline to 122·1 mm Hg (10·5). By contrast, in the group allocated to receive fewer antihypertensive medications, it remained relatively unchanged, moving from 134·8 mm Hg (SD 11·2) at baseline to 132·9 mm Hg (15·3); this corresponded to a mean difference of -10·7 mm Hg (95% CI -17·5 to -4·0). INTERPRETATION: Remotely delivered antihypertensive treatment substantially reduced systolic blood pressure in older adults who are often less represented in trials, with no increase in the risk of serious adverse events. The results of this trial will inform a larger clinical trial focusing on assessing major cardiovascular events, safety, physical functioning, and cognitive function that is currently in the planning stages. These results also underscore the efficiency of decentralised trial designs, which might be of broader interest in other settings.

Photosensitizing antihypertensive medication and risk of skin cancer among postmenopausal women.

BACKGROUND: Few prospective studies exist with an evaluation of a dose-response relationship between use of some photosensitizing antihypertensive medications and skin cancer. PATIENT AND METHODS: We used prospective data from the Women's Health Initiative Observational Study to investigate the association between antihypertensive use and risk of non-melanoma skin cancer (NMSC) and melanoma in postmenopausal women aged 50-79 years at baseline (n  =  64,918). Multivariable Cox proportional hazards regression models were used and hazard ratios (HRs) and 95 confidence intervals (CIs) were calculated. RESULTS: 8,777 NMSC and 1,227 melanoma cases were observed. Use of antihypertensives (HR [95% CI]: 1.12 [1.07-1.18]), ACE inhibitors (1.09 [1.01-1.18]), calcium channel blockers (1.13 [1.05-1.22]), diuretics (1.20 [1.12-1.27]), loop diuretics (1.17 [1.07-1.28]), and thiazides (1.17 [1.03-1.33]) were each associated with higher NMSC risk. NMSC risk linearly increased with use of multiple antihypertensives (p-trend  =  0.02) and with longer duration of use (p-trend < 0.01). Antihypertensives (1.15 [1.00-1.31]), angiotensin-II receptor blockers (1.82 [1.05-3.15]), and diuretics (1.34 [1.13-1.59]) were each associated with elevated melanoma risk. Effect modification by solar radiation exposure was found between antihypertensive use and incidence of melanoma (p-interaction  =  0.02). CONCLUSIONS: Use of antihypertensives overall, and several individual classes thereof, were associated with higher incidence of NMSC and melanoma with dose-response relationship.

Preoperative Renin-Angiotensin System Antagonists Intake and Blood Pressure Responses During Ambulatory Surgical Procedures: A Prospective Cohort Study.

BACKGROUND: There is limited evidence to inform the association between the intake of angiotensin-converting enzyme inhibitors (ACEIs)/angiotensin II receptor blockers (ARBs) and intraoperative blood pressure (BP) changes in an ambulatory surgery population. METHODS: Adult patients who underwent ambulatory surgery and were discharged on the same day or within 24 hours of their procedure were enrolled in this prospective cohort study. The primary outcome of the study was early intraoperative hypotension (first 15 minutes of induction). Secondary outcomes included any hypotension, BP variability, and recovery. Hypotension was defined as a decrease in systolic BP of >30% from baseline for ≥5 minutes or a mean BP of <55 mm Hg. Four exposure groups were compared (no antihypertensives, ACEI/ARB intake <10 hours before surgery, ACEI/ARB intake ≥10 hours before surgery, and other antihypertensives). RESULTS: Of the 537 participants, early hypotension was observed in 25% (n = 134), and any hypotension in 41.5% (n = 223). Early hypotension occurred in 30% (29 of 98) and 41% (17 of 41) with the intake of ACEI/ARBs <10 and ≥10 hours before surgery, respectively, compared to 30% (9 of 30) with other antihypertensives and 21% (79 of 368) with no antihypertensives ( P = .02). Those on antihypertensives also experienced any hypotension more frequently than those who were not on antihypertensives ( P < .001). After adjusting for age and baseline BP in a regression analysis, antihypertensive exposure groups were observed to be associated only with any intraoperative hypotension ( P = .012). In the ACEI/ARB subset, there was no evidence of an association between time since the last ACEI/ARB dose, and hypotension or minimum mean or systolic BP. Compared to normal baseline BP, BP ≥ 140/90 mm Hg increased the odds of early and any hypotension (odds ratio [OR], 3.9; 95% confidence interval [CI], 2.1-7.1 and OR, 7.7; 95% CI, 3.7-14.9, respectively; P < .001). Intraoperative variability in systolic and diastolic BP demonstrated significant differences with age, baseline BP, and antihypertensive exposure group ( P < .001). CONCLUSIONS: Early and any hypotension occurred more frequently in those on antihypertensives than those not on antihypertensives. Unadjusted associations between antihypertensive exposure and intraoperative hypotension were largely explained by baseline hypertension rather than the timing of ACEI/ARBs or type of antihypertensive exposure. Patients with hypertension and on treatment experience more intraoperative BP variability and should be monitored appropriately.

Beta-blocker adjunct therapy as a prospective anti-metastatic with cardio-oncologic regulation.

The prevailing treatment stratagem in cancer therapy still challenges the dilemma of a probable metastatic spread following an initial diagnosis. Including an anti-metastatic agent demands a significant focus to overrule the incidence of treatment failures. Adrenergic stimulation underlying the metastatic spread paved the way for beta blockers as a breakthrough in repurposing as an anti-metastatic agent. However, the current treatment approach fails to fully harness the versatile potential of the drug in inhibiting probable metastasis. The beta blockers were seen to show a myriad of grip over the pro-metastatic and prognostic parameters of the patient. Novel interventions in immune therapy, onco-hypertension, surgery-induced stress, induction of apoptosis and angiogenesis inhibition have been used as evidence to interpret our objective of discussing the potential adjuvant role of the drug in the existing anti-cancer regimens. Adding weight to the relative incidence of onco-hypertension as an unavoidable side effect from chemotherapy, the slot for an anti-hypertensive agent is necessitated, and we try to suggest beta-blockers to fill this position. However, pointing out the paucity in the clinical study, we aim to review the current status of beta blockers under this interest to state how the drug should be included as a drug of choice in every patient undergoing cancer treatment.

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 (20/5 mg) 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 ± 0.3 mmHg at W4 and -12.7 ± 0.5/-7.6 ± 0.3 mmHg 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.

Preeclampsia, antihypertensive medication use in pregnancy and risk of childhood cancer in offspring.

PURPOSE: Preeclampsia is a serious pregnancy complication that presents a significant risk to both the mother and the fetus. Preeclampsia and medications associated with its treatment are potentially linked to increased childhood cancer risk. Therefore, we examined the association between preeclampsia, antihypertensive medications, and childhood cancer in offspring. METHODS: Cases (n = 6,420) and controls (n = 160,484) were obtained from Danish national registries. We performed conditional logistic regression analyses to estimate the association between preeclampsia and childhood cancer risk, and examined the effects of antihypertensive medication use in pregnancy in relation to childhood cancer risk in the offspring with adjustment for relevant covariates. RESULTS: We observed an increased risk of acute lymphoblastic leukemia (ALL) among those whose mothers had preeclampsia (OR = 1.36, 95% CI 1.03, 1.79), especially for severe preeclampsia (OR = 2.36, 95% CI 1.37, 4.08). We also estimated an increased cancer risk in children born to mothers who were prescribed diuretics during pregnancy [OR = 2.09, 95% confidence interval (CI) 1.39, 3.14]. Intake of other antihypertensive medications was not associated with childhood cancer (OR = 0.78, 95% CI 0.50, 1.23). Among women who did not take diuretics in pregnancy, preeclampsia was associated with neuroblastoma (OR = 2.22, 95% CI 1.08, 4.55). CONCLUSION: Our findings suggested an increased risk for certain types of cancer in the offspring of mothers with preeclampsia and an increased risk of cancer with diuretic intake during pregnancy.

Blasting off: persistent hypertension in a child with neuroblastoma.

Hypertension in children with neuroblastoma is uncommon and can be difficult to control due to the potential for multiple underlying causes. We present the case of a pediatric patient with high-grade neuroblastoma which was complicated by hypertensive emergency. The patient had imaging suggestive of renal artery compression, as well as significantly elevated normetaphrine levels. Multiple anti-hypertensive agents, including an angiotensin converting enzyme inhibitor, α- and ß-adrenergic receptor blockers, and a tyrosine hydroxylase inhibitor, were initiated prior to tumor excision. While her blood pressure improved during the post-operative period, she continued to require multiple antihypertensive medications due to residual tumor burden. In this report, we highlight the importance of careful, multidisciplinary management to avoid peri-operative complications in patients with catecholamine-producing tumors.

Efficacy and Safety of a Polypill to Reduce Cardiovascular Events: A Review of Clinical Trials.

ABSTRACT: Cardiovascular disease continues to be the leading cause of mortality globally. Modifiable risk factors, such as hypertension and dyslipidemia, can be managed through lifestyle and pharmacotherapy treatments to reduce the risk of primary and secondary major cardiovascular events in patients with elevated risk. Despite effective and available medications to manage and mitigate cardiovascular risk factors, control rates of hypertension and dyslipidemia are suboptimal, and greater efforts are needed to reduce cardiovascular event rates worldwide. A polypill containing several classes of medications proven to lower cardiovascular risk in a single-dose form has been associated with improved medication adherence over multiple single-ingredient medications and may lead to reduced cardiovascular events. The goal of this article is to review available data from clinical trials assessing the efficacy and safety of polypills compared with placebo or usual care for cardiovascular risk reduction. Three databases were searched (PubMed/MEDLINE, CINAHL, and ScienceDirect) for randomized trials that compared a single polypill with usual care or placebo and reported major adverse cardiovascular events for each study group. A total of 6 trials were selected for inclusion. Several polypill formulations were compared with placebo or usual care with multiple single-ingredient medications in study populations consisting of both primary and secondary prevention patients. Overall, the polypill seems to be associated with reduced major adverse cardiovascular event and comparable safety with usual care treatment with an added benefit of improved adherence over multiple single-ingredient medications. The polypill has potential to be a cost-effective intervention to reduce the global burden of cardiovascular disease.

Survival analysis from the INCREASE study in PH-ILD: evaluating the impact of treatment crossover on overall mortality.

OBJECTIVE: A post-hoc analysis of the INCREASE trial and its open-label extension (OLE) was performed to evaluate whether inhaled treprostinil has a long-term survival benefit in patients with pulmonary hypertension associated with interstitial lung disease (PH-ILD). METHODS: Two different models of survival were employed; the inverse probability of censoring weighting (IPCW) and the rank-preserving structural failure time (RPSFT) models both allow construction of a pseudo-placebo group, thereby allowing for long-term survival evaluation of patients with PH-ILD receiving inhaled treprostinil. Time-varying stabilised weights were calculated by fitting Cox proportional hazards models based on the baseline and time-varying prognostic factors to generate weighted Cox regression models with associated adjusted HRs. RESULTS: In the INCREASE trial, there were 10 and 12 deaths in the inhaled treprostinil and placebo arms, respectively, during the 16-week randomised trial. During the OLE, all patients received inhaled treprostinil and there were 29 and 33 deaths in the prior inhaled treprostinil arm and prior placebo arm, respectively. With a conventional analysis, the HR for death was 0.71 (95% CI 0.46 to 1.10; p=0.1227). Both models demonstrated significant reductions in death associated with inhaled treprostinil treatment with HRs of 0.62 (95% CI 0.39 to 0.99; p=0.0483) and 0.26 (95% CI 0.07 to 0.98; p=0.0473) for the IPCW and RPSFT methods, respectively. CONCLUSION: Two independent modelling techniques that have been employed in the oncology literature both suggest a long-term survival benefit associated with inhaled treprostinil treatment in patients with PH-ILD.
