Cardiovascular disease in COVID-19

The current COVID-19 pandemic is a primarily respiratory illness, manifesting with severe hypoxia and often progressing to acute respiratory distress syndrome (ARDS) and death. However, it is also known to be linked to a wide range of cardiovascular (CV) manifestations that are associated with a very poor prognosis.

Study shows how mast cells regulate calcium levels to control the immune response

Instead of protecting us, the immune system can sometimes go awry, as in the case of autoimmune diseases and allergies. An Ludwig-Maximilian-Universitaet (LMU) in Munich team has dissected how mast cells regulate their calcium levels to keep the immune response under control.

Researchers caution use of chloroquine therapy for patients at higher risk of heart rhythm abnormalities

A patient who met many of the published safety guidelines for chloroquine therapy against COVID-19 was observed to have a very abnormal ECG pattern after treatment began, leading to multiple episodes of torsade de pointes (TdP), a life-threatening arrhythmia in which the lower chambers of the heart beat out of sync with the upper chambers.

Steroidal drugs subvert SARS-CoV-2 interaction with ACE2 receptors

A new study by Italian researchers and published online on the preprint server bioRxiv* in June 2020 reports the ability of several existing steroidal drugs to reduce the binding of the SARS-CoV-2 to the ACE2 receptor. This could help define newer strategies using viral entry blockers to reduce viral load.
