WEDNESDAY, Sept. 16, 2020 (HealthDay Information) — Most individuals now know that COVID-19 could cause blood clots, doubtlessly resulting in paralysis, stroke, heart attack and loss of life.

Whereas it isn’t clear exactly how SARS-CoV-2 causes clots, a brand new examine means that the quantity of a specific protein — referred to as issue V — in a affected person’s blood might have one thing to do with it.

In March, researchers at Massachusetts Common Hospital obtained a blood pattern from a affected person with extreme COVID-19 and observed one thing uncommon. The affected person’s blood had considerably above-normal ranges of issue V.

Researchers then studied greater than 100 sufferers handled within the intensive care unit for COVID-19.

Excessive ranges of issue V had been discovered throughout the group, and almost half of the sufferers had above-normal ranges. When researchers in contrast the samples to historic information, greater than 1 in 10 sufferers had greater issue V ranges than had been seen earlier than on the hospital.

“Apart from COVID-19, I’ve by no means seen anything trigger markedly elevated issue V, and I have been doing this for 25 years,” examine co-author Dr. Elizabeth Van Cott mentioned in a hospital information launch. She is a pathology investigator at Mass Common and a pathology professor at Harvard Medical College.

The examine discovered that sufferers with elevated issue V had been extra prone to have blood clots within the lungs, referred to as pulmonary embolism, and deep vein thrombosis (DVT), or clots within the veins.

Of sufferers with excessive ranges of issue V, one-third had both DVT or a pulmonary embolism, in contrast with 13% of sufferers with decrease ranges.

Whereas sufferers with excessive issue V ranges had been at larger danger for clotting issues, sufferers with decrease issue V ranges had the next danger of loss of life, researchers discovered.

A lower in issue V ranges may point out sufferers are progressing to a severe and infrequently deadly situation through which clotting processes turn out to be overactive, Van Cott and colleagues mentioned.

They mentioned the findings may assist establish which sufferers are at elevated danger of blood clots and loss of life.

The findings had been just lately printed on-line within the American Journal of Hematology.
