SAMA Guidance for managing ethical issues during the COVID-19 outbreak

Posted on Friday, 17 April 2020 14:26

The SAMA Human Rights, Law and Ethics (HRLE) Committee has developed the SARS-CoV-2 (COVID-19): Guidance for Managing Ethical Issues.

 This is a detailed guideline, which highlights the duties and obligations of Doctors and provides ethical guidelines for Doctors during the COVID-19 pandemic.

 To our knowledge this is one of the first guidelines of its kind in the world.

 Although this guideline largely provides ethical guidance for Doctors, the duties and obligations of government and society, in general, are also highlighted.

 The SARS-CoV-2 (COVID-19): Guidance for Managing Ethical Issues is available in two formats (refer attachments):

 

  •         The full guideline with all the detail
  •         An abridged version below, for ease of reading.

 

The abridged version should be read together with the full comprehensive guideline which will soon be made available under the SAMA Governance and Legal tab for all SAMA members, as well as on the SAMA COVID-19 main page.

 SAMA urges practitioners to consider the ethical concepts addressed by the guidance and implement practices recommended with regard to patient- and self-care.

 

Kind Regards

Dr Mark Human

Chair SAMA Human Rights Law and Ethics Committee

 The guidelines are also available on the SAMA COVID19 Webpage under "Doctor resources guidelines and protocols" or at https://www.samedical.org/files/covid19/doctor_resource/SAMA_Ethics%20Guidance%20_COVID-19%20Ethics_2020%207%20Apr.pdf

COVID-19 and Cardiovascular Disease

Posted on Thursday, 16 April 2020 12:20

As many as 25% of patients infected by COVID-19 will have cardiovascular disease and many of them are elderly. Well known cardiologist Dr Tony Dalby of Life Fourways Hospital, Johannesburg provides expert opinion on the management of this high-risk group. He provides valuable guidance on the management of patients with concomitant hypertension, heart failure, arrhythmias and other cardiovascular conditions. He also discusses the controversy about RAAS blockers and reinforces international advice that these agents should not be discontinued. Watch the full presentation here with sincere thanks to deNovo Medica who made this MEDTalksZA available.

COVID-19 infection and risk with angiotensin converting enzyme inhibitors (ACE-I’s) and Angiotensin Receptor Blockers (ARBs)

Posted on Tuesday, 14 April 2020 11:19

The SARS-CoV-2 that causes COVID-19, infects human cells by binding to ACE2 receptors and some animal studies have suggested that this mechanism upregulates ACE2 expression in the heart. A recent article (Lancet Respiratory medicine) speculates that in patients with diabetes and hypertension, ACE2 upregulation from ACEIs and ARBs could increase the risk of developing severe and fatal COVID-19 infection –  https://www.thelancet.com/journals/lanres/article/PIIS2213-2600(20)30116-8/fulltext.

 

There has since been much publicized concerns and hence in response four professional cardiology societies have issued counter statements, despite theoretical concerns that their use might worsen outcomes.The Council on Hypertension of the European Society of Cardiology (ESC) strongly recommends that physicians and patients should continue their usual anti-hypertensive therapy and there is no clinical or scientific evidence to suggest that ACE-I’s and ARBs should be discontinued because of Covid-19 infection – link - https://www.escardio.org/Councils/Council-on-Hypertension-(CHT)/News/position-statement-of-the-esc-council-on-hypertension-on-ace-inhibitors-and-ang. There is also evidence from animal studies that these medications might be paradoxically protective against serious lung complications. A joint statement by the American Heart Association (AHA), American College of Cardiology (ACC), and Heart Failure Society of America (HFSA) has similarly endorsed ongoing renin–angiotensin–aldosterone system (RAAS) antagonists  https://www.acc.org/latest-in-cardiology/articles/2020/03/17/08/59/hfsa-acc-aha-statement-addresses-concerns-re-using-raas-antagonists-in-covid-19. A recent comprehensive special report in the New England Journal of Medicine (NEJM) reviews this issue and supports the positive guidelines from the above societies -  https://www.nejm.org/doi/full/10.1056/NEJMsr2005760. The key NEJM points concluded are:

  •        Abrupt withdrawal of RAAS inhibitors in high-risk patients, including those who have heart failure or have had myocardial infarction, may result in clinical instability and adverse health outcomes.

 

  •        Until further data are available RAAS inhibitors should be continued in patients in otherwise stable condition who are at risk for being evaluated for, or with Covid-19.

General guidance for QTc monitoring in Covid 19 patients

Posted on Tuesday, 14 April 2020 09:19

Dear cardiology community,

I hope you are you staying safe in these unprecedented times.

As many of you are aware, many novel therapies for the treatment of COVID-19 are currently under investigation. Some of these therapies can prolong the QT interval and increase the risk of torsade de pointes (TDP).

Chloroquine, hydroxychloroquine, azithromycin and the lopinavir/ritonavir combination have been shown to increase the QT interval and increase the risk of TDP.  Other modifiable risk factors that can increase the risk of TDP include electrolyte abnormalities (e.g. hypokalaemia) and the use of other potential QT prolonging drugs (a comprehensive list can be found on the website crediblemeds.org or credMeds app).

A baseline QTc interval should be obtained in all patients prescribed these drugs. I have attached a recently published article by the American heart Association, American College of Cardiology and Heart Rhythm Society “Considerations for Drug Interactions on QTc in Exploratory COVID-19 Treatment”. Chloroquine/hydroxychloroquine plus/minus azithromycin should NOT be prescribed in patients with a baseline QTc interval >=500ms.  These drugs should also be stopped if the QTc interval exceeds 500ms.

I have also attached an article and a link to a video on how to calculate and risk stratify patients according to the baseline QTc interval with Professor Michael Ackerman from the Mayo clinic. https://vimeo.com/404736329

As the pandemic evolves, new data will be forthcoming and I will keep you informed of any new developments.

Stay safe.

 

Ashley Chin and Andrew Thornton
