International Study Identifies Risks for Long COVID in Children

Nearly 6 percent of children who presented to the Emergency Department (ED) with COVID-19 reported symptoms of long COVID 90 days later, according to a study conducted in eight countries and published in JAMA Network Open. Initial hospitalization of 48 or more hours, four or more symptoms at the initial ED visit, and age 14 years or older were associated with long COVID.

Long COVID poses risks to vaccinated people, too

Vaccinated people with mild breakthrough COVID-19 infections can experience debilitating, lingering symptoms that affect the heart, brain, lungs and other parts of the body, according to researchers at Washington University School of Medicine in St. Louis and the Veterans Affairs St. Louis Health Care System. However, a new study of more than 13 million veterans also found that vaccination against the virus that causes COVID-19 reduced the risk of death by 34% and the risk of getting long COVID-19 by 15%, compared with unvaccinated patients infected with the virus.

Researchers on the Trail to Unraveling Long COVID-19

Long COVID-19 syndrome, in which symptoms last a year or longer beyond infection, impacts about 30 percent of survivors of the coronavirus.
Lina Shehadeh, Ph.D., professor of medicine in the Interdisciplinary Stem Cell Institute and Division of Cardiology at the University of Miami Miller School of Medicine, received a $1 million grant from the American Heart Association to study long COVID.

Some cases of long COVID-19 may be caused by an abnormally suppressed immune system, UCLA-led research suggests

Researchers studying the effect of the monoclonal antibody Leronlimab on long COVID-19 may have found a surprising clue to the baffling syndrome, one that contradicts their initial hypothesis. An abnormally suppressed immune system may be to blame, not a persistently hyperactive one as they had suspected.

Previously Healthy Young Adults with ‘Long COVID’ Show Vascular Dysfunction in Limbs, but Not Brain

A first-of-its-kind study of young adults with positive COVID-19 tests from more than 4 weeks ago found that those who were still symptomatic (i.e., long-haulers) had impaired blood vessel function in their limbs, but not brains. Asymptotic participants had blood vessel function similar to controls.

Among COVID-19 survivors, an increased risk of death, serious illness

A new study from Washington University School of Medicine in St. Louis shows that even mild cases of COVID-19 increase the risk of death in the six months following diagnosis and that this risk increases with disease severity. The comprehensive study also catalogues the wide-ranging and long-term health problems often triggered by the infection, even among those not hospitalized.

UCLA seeks volunteers for study of COVID-19’s impact on health to support “longhaul” survivors

UCLA researchers are seeking participants for an innovative study examining the impact of COVID-19 on survivors who continue battling health issues long after they were infected and thought to have recovered, known informally as “long COVID” and “longhaulers.”
