Management of the post-COVID-19 condition—often referred to as long COVID—is a challenge for health-care professionals because of the heterogeneity and complexity of its clinical manifestations and the probable need for multidisciplinary management approaches.1 Identification and understanding of modifiable determinants associated with manifestations of long COVID would help in the adaptation of treatment pathways for particular phenotypes.1 In The Lancet Respiratory Medicine, the PHOSP-COVID Collaborative Group2 report the latest results from the UK-based, multicentre, prospective Post-hospitalisation COVID-19 (PHOSP-COVID) study, in which the investigators identified systemic inflammation and obesity as factors that might be associated with long COVID, representing potentially treatable traits in people with more severe post-COVID-19 symptoms.
In the current report, the PHOSP-COVID Collaborative Group found increased levels of several biomarkers related to systemic inflammation and lung damage in individuals with more severe physical and mental health impairments 1 year after hospital discharge. The presence of increased levels of systemic inflammatory biomarkers (eg, cytokines) in individuals with severe acute COVID-19 has been reported previously.3 Moreover, the use of anti-inflammatory agents such as corticosteroids4 or interleukin-6 (IL-6)-blocking agents5 has been found to be associated with positive outcomes in patients hospitalised with acute COVID-19.
