According to the research of scientists from the American Cleveland Clinic, the risk of hospitalization and death in COVID-19 patients who struggle with breathing disorders during sleep and hypoxia during sleep increases by over 30 percent.

The team led by Dr. Reena Mehra analyzed the data collected from nearly 5.5 thousand people. Cleveland Clinic patients in the USA. It turned out that although patients with sleep-disordered breathing and sleep-related hypoxia do not have an increased risk of developing COVID-19, they have a clearly worse clinical prognosis when they develop the disease. The research results were published in the journal “JAMA Network Open”.

“ As the COVID-19 pandemic continues, and the disease affects individual patients very differently, it is crucial to improve our ability to predict who will tolerate it worse. This will enable us to react appropriately and better allocate resources, says Dr. Mehra. “ Our study greatly improved understanding of the relationship between sleep disorders and the risk of an unfavorable course of COVID-19. It shows that inflammatory biomarkers may be responsible for this relationship, he added.

For the purposes of the study, scientists used the COVID-19 case registry belonging to their clinic, containing data of almost 360,000. patients, of which 5.4 thous. also had a documented medical history related to sleep. The authors analyzed the course of the disease (severity of symptoms) in those people who both had a positive SARS-CoV-2 test and current sleep test results. They also considered any comorbidities such as obesity, diabetes, heart disease, lung disease, and cancer, as well as smoking.

It found that those patients who suffered from sleep-related breathing difficulties and sleep-related hypoxia had a 31 percent higher risk of hospitalization and death from COVID-19.

‘Our finding has significant implications as reducing hospital admissions and mortality is a key factor in reducing the burden on health systems,’ emphasizes Dr Cinthya Pena Orbea, senior author of the paper. If sleep-related hypoxia does translate into a worse prognosis for COVID-19, strategies should be in place to identify patients with these types of problems and prioritize their treatment, she added.
