Sleep is an important modulator of the immune response, whereby sleep disturbances (ie,poor sleep quality, insufficient sleep and/or primary sleep disorder, obstructive sleepapnea (OSA)) contribute to inflammatory disease risk and dysregulation of immune responsein front of infectious agents.The objective of this study is to evaluate the impact of undiagnosed and non-treatedsleep disorders on innate immunity in a cohort of COVID-19 patients and the role oftrained immunity induced by influenza vaccination in the innate immune response.
Sleep and immune system have reciprocal relationship. Sleep has a restorative role on
immune system, influencing innate and adaptive immunity and sleep disorders can decrease
immune response.
Healthy innate immunity is crucial into regulation of the response against SARS-CoV-2.
The hypothesis of the study is that the innate immunity response is blunted by sleep
disorders and, this mitigated immune response, could influence on COVID-19 severity.
Impaired immune response in patients with sleep disorders could be ameliorated inducing
trained immunity by influenza vaccine.
Biological: Influvac Tetra
All participants will take influenza vaccine (Influvac Tetra, Abbott Biologicals, IL,
USA) and the trained immune response will be evaluated.
