Common hypertension drugs do not increase risk of severe, fatal COVID-19 infection

A new Northwestern Medicine study in mice found a widely used class of drugs to treat patients with hypertension, cardiovascular disease and diabetic kidney disease - many of whom are elderly -- does not increase the risk of developing a severe and potentially fatal COVID-19 infection, as previously feared.

Fusion protein may help treat pulmonary arterial hypertension

Pulmonary arterial hypertension (PAH) is an insidious disease. Symptoms may begin slowly, and even before they appear, extensive damage has caused the obstruction of small arteries leading to increased blood pressure in the lungs.

Autopsies reveal unexpected changes in the hearts of COVID-19 patients

A series of autopsies conducted by LSU Health New Orleans pathologists shows the damage to the hearts of COVID-19 patients is not the expected typical inflammation of the heart muscle associated with myocarditis, but rather a unique pattern of cell death in scattered individual heart muscle cells.

Why doctors keep monitoring kids who recover from mysterious COVID-linked illness

Israel Shippy doesn’t remember much about having COVID-19 — or the unusual auto-immune disease it triggered — other than being groggy and uncomfortable for a bunch of days. He’s a 5-year-old, and would much rather talk about cartoons, or the ideas for inventions that constantly pop into his head.

Certain antibodies may cause the dangerous part of COVID-19 disease

A new study out of the Netherlands and published on the preprint server bioRxiv* in July 2020 discusses the commonly observed phenomenon of COVID-19 progression at 1-2 weeks from the onset of the earliest symptoms. This is ascribed to the overactivation of the inflammatory signaling cascade triggered by a hyperactive adaptive immune reaction, commonly called the cytokine storm.
