“Dr Betty Raman, from the University of Oxford and one of the lead investigators on the study, says it is clear that those living with long-COVID symptoms are more likely to have experienced some organ damage.”
The biggest impact was seen on the lungs, where MRI scans were 14 times more likely to show abnormalities. Scans were also three times more likely to show abnormalities in the brain, and twice as likely in the kidneys, among people who had severe COVID.
The article Multiorgan MRI findings after hospitalisation with COVID-19 in the UK (C-MORE): a prospective, multicentre, observational cohort study was published September 22, 2023 in The Lancet Respiratory Medicine.
After hospitalisation for COVID-19, people are at risk of multiorgan abnormalities in the medium term. Our findings emphasise the need for proactive multidisciplinary care pathways, with the potential for imaging to guide surveillance frequency and therapeutic stratification.
ABOUT LONG-COVID
Long-standing multiorgan impairment following SARS-CoV-2 infection has been a major concern for individuals recovering from severe disease and is thought to be caused by a multitude of factors, including direct viral cytotoxicity, chronic inflammation, ischaemic injury, acute reactivation of other viruses, metabolic derangements, and acute treatment effects (especially invasive ventilation). Numerous reports of delayed organ complications such as myocarditis, stroke, and pulmonary emboli have led to speculations that the multiorgan dysfunction caused by COVID-19 might be responsible for impaired recovery and ongoing symptoms in individuals, a condition referred to as long COVID.
