Aldosterone biosynthesis induced by ACTH and angiotensin II in newborn rat adrenocortical cells transfected by c-EJ-Ha-ras oncogene

1991

Abstract Adrenocortical cells were obtained by fractionated trypsination of newborn rat adrenal glands and transfected with a plasmid containing the EJ T24 -Ha-ras oncogene. Isolation of adhesive cells led to a proliferative cell line with an overexpression of 21 kDa ras protein. These cells incubated with corticosterone or deoxycorticosterone as the precursor produced a high level of 18-hydroxycorticosterone and aldosterone as identified by gas chromatography- mass spectrometry. ACTH and angiotensin II increased the basal production of aldosterone nineteen-fold and six-fold respectively. Under ACTH stimulation the ratio between aldosterone and 18-hydroxycorticosterone production was 1:3. T…

Carboxyl nonsteroidal anti-inflammatory drugs are efficiently glucuronidated by microsomes of the human gastrointestinal tract.

2004

Limited studies have been carried out on the biotransformation of carboxyl nonsteroidal anti-inflammatory drugs (NSAIDs) in the liver. However, the role of the intestine in NSAID metabolism has not been investigated. In this report, the contribution of UDP-glucuronosyltransferases (UGTs) in the human gastrointestinal (GI) tract from five donors to the glucuronidation of the NSAIDs, RS-ketoprofen, S-naproxen, RS- and S-etodolac, was investigated. UGT activity and, for some donors, mRNA levels were evaluated. All NSAIDs were glucuronidated throughout the GI tract; however, glucuronidation was low in stomach and duodenum as compared to the remainder of the intestine. RT-PCR analysis demonstrat…

Treatment of high blood pressure in elderly and octogenarians: European Society of Hypertension statement on blood pressure targets

2016

Abstract The European Society of Hypertension recommend the following main rules for treatment of hypertension in elderly and octogenarians: 1) In elderly hypertensives with SBP ≥ 160 mmHg there is solid evidence to recommend reducing SBP to between 140 mmHg and 150 mmHg. 2) In fit elderly patients less than 80 years old treatment may be considered at SBP ≥ 140 mmHg with a target SBP < 140 mmHg if treatment is well tolerated. 3) In fit individuals older than 80 years with an initial SBP ≥ 160 mmHg it is recommended to reduce SBP to between 150 mmHg and 140 mmHg. 4) In frail elderly patients, it is recommended to base treatment decisions on comorbidity and carefully monitor the effects of tr…

The Renal Dangers of an Increased Cardio-Ankle Vascular Index

2020

Although a number of longitudinal investigations assessed the ability of aortic PWV to predict the development of kidney disfunction or progression of renal disease, little is known about the association of CAVI with the risk of renal function deterioration. In the current issue of the American Journal of Hypertension is published a paper of Itano S et al, that add a new piece of evidence in this scenario. The authors analyzed data from the national health check-up system in Japan, including 24.297 participants with normal baseline kidney function. They found that those with CAVI measurements ≥8.1 had a higher risk for CKD events compared to their counterparts with CAVI measurements &lt;8.1…

Prognostic impact of systolic blood pressure in acute heart failure with preserved ejection fraction in older patients

2021

Abstract Aims Recent guidelines recommend a systolic blood pressure (SBP) target below 130 mmHg in heart failure patients with preserved ejection fraction (HFpEF), whatever their age. We investigated whether this intensive SBP control was associated with better survival in very old adults hospitalized for acute HFpEF. Methods and results We conducted an observational study in an acute geriatric unit: all consecutive patients discharged from hospital for acute heart failure from 1 March 2019 to 29 February 2020 with a diagnosis of HFpEF were included. Re‐hospitalization and all‐cause mortality at 1 year were compared according to the mean SBP at discharge (patients with a mean SBP < 130 mmHg…

The Role of Ambulatory Blood Pressure Monitoring in Diagnosis of Hypertension and Evaluation of Target Organ Damage

2010

The goal of blood pressure (BP) measurement in children and adolescents is to provide strategies for promoting cardiovascular health which should be integrated into a comprehensive pediatric health-care program. Blood pressure, however, is a parameter that changes on a beat-to-beat basis in response to a variety of physiological and environmental stimuli. Nevertheless, casual BP measurement has provided the basis for present knowledge of the potential risk associated with hypertension (1) and has guided patient management for many years (2). A few BP measurements obtained in the office, on the contrary, may not necessarily reflect the true BP of an individual. Subsequently, a better charact…

P124 The impact of the new American college of cardiology/american heart association (ACC/AHA) definition of hypertension on atherosclerotic vascular…

2020

Background The 2017 ACC/AHA guidelines define hypertension as ≥130/80 mmHg instead of ≥140/90 mmHg. Studies in systemic autoimmune diseases, where blood pressure (BP) is fluctuating over time, were not considered. Our aim was to assess the impact of the new definition on the prevalence and incidence of atherosclerotic vascular events (AVEs) in systemic lupus erythematosus (SLE). Patients-Methods SLE patients with at least two years of follow-up and no previous AVEs were divided in three groups (≥140/90 mmHg, 130–139/80–89 mmHg and Results 1532 patients satisfied the inclusion criteria (88.1% females, mean age at baseline 36.2±14.3 years, mean disease duration 6.1±6.3 years). The prevalence …
