Could sustained inflammation following mild to moderate COVID-19 be a driver of long COVID?

A new study describes the discovery of sustained though low-level rises in inflammatory mediators and immune cells, as well as the loss of some subsets of naïve un-activated cells. This may indicate a widespread though muted immune-mediated inflammatory response in these patients.

Study shows durable specific humoral immunity against SARS-CoV-2 after mild or asymptomatic infection

As a part of the COMMUNITY (COVID-19 Immunity) study, researchers from Sweden reveal long-lasting IgG neutralizing antibody response against spike glycoprotein of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in the vast majority of convalescent individuals – even after asymptomatic or mild infection. Their results are currently available on medRxiv* preprint server.

Study offers explanation for silent hypoxemia in COVID-19 patients

One of the physiopathological characteristics of COVID-19 that has most baffled the scientific and medical community is what is known as "silent hypoxemia" or "happy hypoxia".

Severe COVID-19 linked to age, body mass index and ABO blood group

With the COVID-19 pandemic caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infecting over 50 million people worldwide with hundreds of thousands experiencing severe respiratory illness, researchers have been trying to find the factors associated with severe disease. From the start of the pandemic in March this year, several studies have indicated heart disease, high blood pressure, diabetes, obesity, etc. could be linked to severe disease. Now German researchers have published a study on the association between severe respiratory infection caused by SARS CoV-2 and factors such as age, body mass index (BMI) and ABO blood group.
