SARS-CoV-2 can cause lasting damage to cells’ energy production

At the beginning of the COVID-19 pandemic, the virus responsible for the disease, SARS-CoV-2, was feared for its devastating damage to the lungs. But it quickly became apparent that the virus can infect organs and tissues throughout the body, including the heart, brain, kidneys, and blood vessels.

Much of the resulting dysfunction was thought to be the result of inflammation, the immune system’s response to infection. But research has suggested that effects on mitochondria may also play a role in organ damage from SARS-CoV-2 infection. Mitochondria are the powerhouses of cells, producing most of the energy they need.

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.

Some seniors infected with Omicron variants were more susceptible to reinfection, not less: McMaster study

In a sign that scientists still don’t fully understand how some COVID-19 variants manage to evade the immune system, a new Ontario study has found that retirement- and long-term-care home residents infected during the first Omicron wave were 20 times more likely to get reinfected by the virus than those who avoided a prior infection.

The surprising finding by researchers at McMaster University runs counter to the prevailing wisdom that a previous COVID infection affords protection against future infections, at least in the older adults who participated in the study.

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.

How COVID-19 Changes the Immune System

By Alice Park

In a paper published on August 18 in the journal Cell, scientists report that innate immune cells—a critical part of the immune system activated to battle COVID-19—remain altered for at least a year after infection. The finding suggests that these cells may play a role in some of the lingering symptoms associated with Long COVID, although more studies are needed to confirm that connection.

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.

In a new study, researchers used Medicare data to characterize the long-term risk of death and hospital readmission after being hospitalized with COVID-19 among patients 65 years and older. The study demonstrates that among patients who were admitted to a hospital with COVID-19 and discharged alive, the risk of post-discharge death was nearly twice that observed in those who were discharged alive from an influenza-related hospital admission.

By Children’s Hospital of Philadelphia

This study provides us with strong evidence that we need to stop looking at COVID-19 as strictly an upper respiratory disease and start viewing it as a systemic disorder that impacts multiple organs. The continued dysfunction we observed in organs other than the lungs suggests that mitochondrial dysfunction could be causing long-term damage to the internal organs of these patients.

With this test, there are no nasal swabs and no waiting 15 minutes for results, as with home tests. A person simply blows into a tube in the device, and an electrochemical biosensor detects whether the virus is there. Results are available in about a minute.
