Aldosterone News and Research

RSS

Aldosterone is a steroid hormone made by the adrenal cortex (the outer layer of the adrenal gland). It helps control the balance of water and salts in the kidney by keeping sodium in and releasing potassium from the body. Too much aldosterone can cause high blood pressure and a build-up of fluid in body tissues. Aldosterone is a type of mineralocorticoid hormone.

American Heart Association honors UVA professor for contributions to cardiovascular research

Robert M. Carey, MD, Professor of Medicine at the University of Virginia School of Medicine, has been named a Distinguished Scientist of the American Heart Association for his "extraordinary contributions" to cardiovascular research.

Common heart drugs are safe for patients hospitalized with COVID-19

Heart patients hospitalized with COVID-19 can safely continue taking angiotensin-converting enzyme (ACE) inhibitors and angiotensin receptor blockers (ARBs), according to the BRACE CORONA trial presented in a Hot Line session today at ESC Congress 2020.

Inhaled steroids reduce SARS-CoV-2-related genes in COPD

A new study published on the preprint server medRxiv* aims to explore the effects of treatment with ICS on the expression of specific genes related to SARS-CoV-2 infection in bronchial epithelial cells in a prospective interventional design.

Antihypertensives reduce severity of Covid-19 infection and death

Medication for high blood pressure could improve Covid-19 survival rates and reduce the severity of infection - according to new research from the University of East Anglia.

Antihypertensives improve COVID-19 survival rates

Previous studies have also linked hypertension to severe coronavirus disease (COVID-19). Now, a new study by researchers at the University of East Anglia's Norwich Medical School has found that the risk of severe COVID-19 and death was reduced for patients with high blood pressure who were taking Angiotensin-Converting Enzyme inhibitors (ACEi) or Angiotensin Receptor Blockers (ARB).

Large-scale analysis of Alport syndrome reveals the effectiveness of existing treatments

A large-scale analysis of the clinical characteristics of Alport syndrome in Japanese patients has revealed that the effectiveness of existing treatment with ACE inhibitors and/or angiotensin receptor blockers (RAS inhibitors) varies depending on the type of mutation in the syndrome's causal gene (COL4A5).

UTHealth physicians investigate blood pressure drug's effect on improving COVID-19 outcomes

An interventional therapy aimed at improving survival chances and reducing the need for critical care treatment due to COVID-19 is being investigated by physicians at The University of Texas Health Science Center at Houston.

SARS-CoV-2 a dagger to the aging heart

Researchers in Europe have shown that genes involved in severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection are expressed to a higher degree in older heart muscle cells (cardiomyocytes) than they are in younger cardiomyocytes.

ACE inhibition in kidney could influence pathogenesis of SARS-CoV-2

The dynamics of angiotensin-converting enzyme 2 (ACE2) expression in the kidney could have implications for the infectivity and pathogenicity of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), say researchers.

Low potassium levels in COVID-19 disease

Now a new study by an Italian team of researchers published in June 2020 on the preprint server medRxiv reports that potassium levels are often low in COVID-19 disease, mostly due to the urinary loss of potassium.

High-salt diet may modulate the gut microbiome

Particularly in females with untreated hypertension, reducing salt intake to what's considered a healthier level appears to be good for both their gut microbiome and their blood pressure, scientists report.

RAAS inhibitors are safe to use in COVID-19 patients, study shows

The coronavirus disease (COVID-19) is a novel illness that has spread across the globe in just five months. Caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the viral infection binds to the angiotensin-converting enzyme 2 (ACE2) to enter and invade cells.

Main receptors used by SARS-CoV-2 for cell entry are absent in the human placenta

Although severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is unlikely to infect human placenta through the canonical cell entry mediators, Wayne State University researchers showed that other interacting proteins may still play an important role during the viral infection. The study is currently available on the preprint server bioRxiv.

Sleep apnea may increase the risk of severe COVID-19, say researchers

An analysis conducted by researchers at the University of Turku and Turku University Hospital in Finland has suggested that obstructive sleep apnea (OSA) may be a risk factor for severe coronavirus disease 2019 (COVID-2019).

Indo-Mediterranean style diets can cause decline in pre-heart failure, arrhythmias

The role of diets in the pathogenesis of cardiac dysfunction is controversial. However, it is well known that Western diet causes oxidative stress and has pro-inflammatory effects, whereas Mediterranean style diets are anti-inflammatory.

ACE inhibitors should not be discontinued over fears about COVID-19, say researchers

Researchers in Europe have found no evidence to support previous reports that the use of drugs that target the renin-angiotensin-aldosterone system (RAAS) increases susceptibility to coronavirus disease 2019 (COVID-19). The research is published in the European Heart Journal.

High blood pressure drugs found to be safe for COVID-19 patients

Despite concerns expressed by some experts, common high blood pressure drugs did not increase the risk of contracting COVID-19 - or of developing severe disease - in a study of 12,594 patients.

New clinical trial to assess whether hypertension drug may reduce COVID-19 severity

Researchers at University of California San Diego School of Medicine have launched a clinical trial to investigate whether a drug approved for treating high blood pressure, heart failure and diabetic kidney disease might also reduce the severity of COVID-19 infections, lowering rates for intensive care unit admissions, the use of mechanical ventilators and all-cause mortality.

Radboudumc researchers find essential mechanism in the disease process of COVID-19

Researchers at the Radboud University Medical Center seem to have found an essential mechanism in the disease process of COVID-19, which has so far been overlooked.
