Researchers have developed a computational model that predicts how likely a person is to develop long COVID, based on an analysis of more than 6,500 proteins found in blood.

In a study published on 18 January in Science, the team compared blood samples from people who tested positive for COVID-19 with ones from healthy adults, and found notable differences in the composition of proteins in people with long COVID, those who recovered and those who were never infected.

The analysis suggests that proteins involved in immune responses, blood clotting and inflammation could be key biomarkers in diagnosing and monitoring long COVID, which affects an estimated 65 million people worldwide.

Why some doctors see COVID as a new risk factor for cardiovascular disease

Why some doctors see COVID as a new risk factor for cardiovascular disease

The severity of the infection doesn’t seem to make a difference. These complications can occur even in people who have very mild symptoms. The big surprise is how much this can affect younger people. Studies are showing that even young, active people can experience heightened risk of these complications.

—Dr. Peter Liu, University of Ottawa Heart Institute

High blood pressure, high cholesterol, diabetes, obesity: These are some of the well-known risk factors that can put people at heightened risk for heart attack and stroke.

Now some health experts say COVID-19 should be added to that list.

Long COVID: The hunt for causes and cures

Hannah Davis misses her old self. Like so many people around the world, she has seen her life upended by long COVID, which has made many once-routine activities impossible. The 32-year-old has stopped working at her job in the field of machine learning and generative models. It’s too cognitively taxing; the lights from display monitors are disorienting. Merely standing up from a sitting position causes her heart rate to shoot to 170 beats per minute, the equivalent of doing a good jog.

High levels of 2 blood-clotting proteins may portend post-COVID brain fog

High levels of two blood biomarkers during infection could predict cognitive dysfunction, or “brain fog,” among COVID-19 survivors 6 and 12 months after hospitalization, according to a UK study published yesterday in Nature Medicine.

Blood Clotting Proteins Might Help Predict Long COVID Brain Fog

Many people who have long COVID—a condition in which health issues persist months after infection—report struggling with “brain fog,” recurring memory and concentration lapses that make it difficult to function in everyday life. Now a new study has found these cognitive problems could result from blood clots triggered by infection, possibly through mechanisms like those that cause some types of dementia. These clots leave telltale protein signatures in blood, suggesting that testing for them could help predict, diagnose and possibly even treat long COVID.

Long COVID still worrisome 2 years after infection

Our findings highlight the substantial cumulative burden of health loss due to long COVID and emphasize the ongoing need for health care for those faced with long COVID. It appears that the effects of long COVID for many will not only impact such patients and their quality of life, but potentially will contribute to a decline in life expectancy and also may impact labor participation, economic productivity, and societal well-being.

Long Covid symptoms create a greater burden of disability than heart disease or cancer, new study shows

People who survived Covid-19 early in the pandemic, before there were vaccines, continued to be at higher risk for a slew of health problems for up to two years after they got over their initial infections, compared to others who didn’t test positive, a new study finds, and that was especially true if they were hospitalized.

These health problems include heart problems, blood clots, diabetes, neurologic complications, fatigue and difficulties with mental health and have come to be known collectively as long Covid.

Many long-covid symptoms linger even after two years, new study shows

People who endured even mild cases of covid-19 are at heightened risk two years later for lung problems, fatigue, diabetes and certain other health problems typical of long covid, according to a new study that casts fresh light on the virus’s true toll.

The analysis, published Monday in the journal Nature Medicine, is believed to be the first to document the extent to which an array of aftereffects that patients can develop — as part of the diffuse and sometimes debilitating syndrome known as long covid — linger beyond the initial months or year after they survived a coronavirus infection.

Heart attack-caused deaths rose during every virus surge. Worse, young people aren’t supposed to have heart attacks but Cheng’s research documented a nearly 30% increase in heart attack deaths among 25- to 44-year-olds in the pandemic’s first two years.

Are repeat COVID infections dangerous? What the science says

Published April 26, 2023

Nature

April 26, 2023

“People with repeat infections were twice as likely to die and three times as likely to be hospitalized, have heart problems or experience blood clots than were people who were infected only once. In a surprising twist, vaccination status didn’t seem to have an impact — although other studies show vaccines to be protective. Whether these results hold true for the general population is up for debate. The Veterans Affairs cohort was made up mostly of older white men, which is not representative of the wider population.”
