Researchers at the Sino-Japanese Friendship Hospital analyzed data from 1,192 people who were taken to Jin Yin Tan Hospital in Wuhan, China, and discharged from January 7 to May 29, 2020.
The researchers examined patients at six months, 12 months, and two years after discharge Ask for your personal assessment of your symptoms. Participants were also evaluated on more objective medical tests, including lung function tests, CT scans, and six-minute walk tests.
Overall, the participants were in poor condition two years later. Those who experienced persistent symptoms of Covid-19 reported pain, fatigue, sleep disturbances, and mental health problems. Patients with higher respiratory support while in hospital have other longer-term lung problems.
People with chronic symptoms also went to the doctor more often than before the pandemic. They had difficulty practicing and usually reported a poorer quality of life. Most have returned to work, but it is unclear whether they are working at the same level as before the illness.
Doctor. Ben Kao, another author of a study at the China-Japan Friendship Hospital, hopes the study will encourage clinicians to ask follow-up questions to their Covid-19 patients even years after the initial infection.
“There is a clear need to provide ongoing support to a significant proportion of people infected with Covid-19 and to understand how vaccines, new treatments and variations will affect long-term health effects,” Kao said in a press release.
Investigate some of the limitations. The researchers did not compare the results with people who were hospitalized for reasons other than the Covid virus to see if they also had long-term symptoms. They compared the hospitalized group to community members who did not have Covid-19; This group also had health problems a year later, but this happened to about half of the people in the hospital group.
Another limitation was that the study involved a hospital, so the results may not be universal for all Covid-19 patients in the hospital. At the beginning of a pandemic, patients were often kept in hospital for longer than they are now, and this can affect the duration of symptoms. Because the study was conducted in the early stages of a pandemic, it is unclear whether people with subsequent variants of the coronavirus or those who were vaccinated would have similar results.
“The only thing I know I can give Covid patients safely for a long time is vaccination,” said Sanjavi, who was not involved in the study. “When we compare unvaccinated patients to vaccinated patients and see a long-term symptomatic presence of Covid, vaccinated patients have fewer severe symptoms and are less common during prolonged Covid disease.”
“Right now, it looks like these patients are sometimes in retrospect,” Sanjavi said.
“Research shows how many people need help. I don’t know if you’ve tried to book an emergency room, but it probably takes weeks or even months in many places. And this is just for a health check – forget the long Covid thing. It’s much longer, ”he said.
Sanjavi said more doctors should also be trained to help people with prolonged Covid-19. “Our healthcare system is not prepared for the kind of patient flow that this disease brings”
Erlandson said so many people wanted to know more about Long Covid that his colleagues didn’t even have to disclose the experience; There is a waiting list for admission.
The new study is in line with what employees see in these long-term clinics.
“This is similar to what we hear patients say in the US, they still have symptoms two years later, especially in the first group of patients in the epidemic. We hear this anecdotally, so it’s always good to see things published,” said Erlandson, who was not in the study. experience similar symptoms, the most common of which are difficulty sleeping and tiredness.
He stressed that people do not need to be hospitalized because of Covid-19 until they have chronic symptoms, and hopes future research will determine how long those in hospital suffer.
Erlandson also noted that some study participants recovered after 12 months and worsened after two years.
“I think these lengthy studies are interesting to see that it’s not a gradual improvement,” he said. “People vary in terms of improvements.”
Erlandson said he is curious to know if participants recover after these two years or whether Covid-19 will become a chronic disease. Doctors can treat certain symptoms, but there is no specific long-term treatment for COVID-19.
“Unless they receive some form of treatment, I am concerned that this will have long-term effects on the disability and functioning of some patients,” he said.
