Lengthy COVID, often known as post-acute sequelae of SARS-CoV-2 an infection (PASC), is a situation the place people proceed to expertise signs or develop new signs after recovering from acute COVID-19 an infection. The signs of lengthy COVID will be wide-ranging and will embrace fatigue, shortness of breath, chest ache, joint ache, headache, mind fog, issue sleeping, and melancholy or nervousness. In accordance with a current intensive examine on lengthy COVID sufferers spanning over 12 months, 59% of sufferers continued to exhibit organ harm a 12 months after experiencing preliminary signs, together with those that weren’t severely affected on the time of their virus analysis.
Organ harm continued in 59% of lengthy COVID sufferers a 12 months after preliminary signs, even in these not severely affected when first recognized with the virus, according to a comprehensive new study.
A new comprehensive study of organ impairment in long COVID patients over 12 months shows organ damage persisted in 59% of patients a year after initial symptoms, even in those not severely affected when first diagnosed with the virus.
The study, published in the Journal of the Royal Society of Medicine, focused on patients reporting extreme breathlessness, cognitive dysfunction, and poor health-related quality of life; 536 long COVID patients were included in the study. Thirteen percent were hospitalized when first diagnosed with COVID-19, while 32% of people taking part in the study were healthcare workers.
Of the 536 patients, 331 (62%) were identified with organ impairment six months after their initial diagnosis. These patients were followed up six months later with a 40-minute multi-organ MRI scan (Perspectum’s CoverScan), analyzed in Oxford.
The findings confirmed that 29% of patients with long COVID had multi-organ impairment, with persistent symptoms and reduced function at six and 12 months. 59% of long COVID patients had single organ impairment 12 months after initial diagnosis.
Senior author Professor Amitava Banerjee (UCL Institute of Health Informatics), said: “Symptoms were common at six and 12 months and associated with female gender, younger age, and single organ impairment.”
The study reported a reduction in symptoms between six and 12 months (extreme breathlessness from 38% to 30% of patients, cognitive dysfunction from 48% to 38% of patients, and poor health-related quality of life from 57% to 45% of patients).
Professor Banerjee added: “Several studies confirm persistence of symptoms in individuals with long COVID up to one year. We now add that three in five people with long COVID have impairment in at least one organ, and one in four have impairment in two or more organs, in some cases without symptoms.”
He said: “Impact on quality of life and time off work, particularly in healthcare workers, is a major concern for individuals, health systems and economies. Many healthcare workers in our study had no prior illness, but of 172 such participants, 19 were still symptomatic at follow-up and off work at a median of 180 days.”
The underlying mechanisms of long COVID remain elusive, say the researchers, who did not find evidence by symptoms, blood investigations or MRI to clearly define long Covid subtypes. They say that future research must consider associations between symptoms, multi-organ impairment and function in larger cohorts.
Professor Banerjee concluded: “Organ impairment in long Covid has implications for symptoms, quality of life and longer-term health, signaling the need for prevention and integrated care for long COVID patients.”
