Summary

A new virus to humans, first identified in December 2019, is causing a global pandemic with over 1 million infections and many thousands of deaths. The virus, SARS-CoV2, leads to coronavirus disease 2019 (COVID-19), which mainly affects the breathing system. Around 1 in every 5 people with COVID-19 have more severe infection needing treatment in hospital. Up to half of them require help with breathing in an intensive care unit. Information we have so far about COVID-19 suggests that people with underlying conditions, such as high blood pressure and heart disease, or older people are at higher risk of having severe illness. Scientists do not yet understand why but think it may be related to the immune system.

SARS-CoV2 activates the immune system causing inflammation in the lungs, which is also seen in circulating immune cells in the blood. Preliminary reports show that the response of the immune system can be inappropriate, both overactive and also poorly responsive (exhausted). Changes in the type and function of immune cells have been linked to increased risk of severe disease or death from COVID-19.

In this study, the investigators will look for markers of immune function when a person first attends hospital, which can be used to predict whether they will go on to have a more severe infection. This will help treat patients more effectively, for example, by moving high risk patients to an intensive care setting at an early stage. The team will investigate the immune system in detail in 200 patients with COVID-19 attending University Hospitals Plymouth. The investigators will look for changes in the number, type and function of circulating immune cells and measure whether these changes are linked to severity of the infection or death. The investigators will use established techniques to measure immune function that could be rapidly put into routine hospital care to help guide treatment for individual patients.
