COVID-19 Patients may not Recover Months after Diagnosis, Chinese Study Reveals


The authors also mentioned that some patients went on to develop kidney problems post-Covid-19 discharge.

In the study, the scientists interviewed the hospitalised patients using questionnaires to assess their symptoms and health-related quality of life.

"To our knowledge, this study is the largest cohort study with the longest follow-up duration for the consequences of adult patients discharged from hospital recovering from Covid-19", wrote researcher Chaolin Huang, of Jin Yin-tan Hospital, Wuhan, China, and colleagues in The Lancet, published online January 8.

Follow-up blood antibody tests from 94 patients after six months revealed that levels of neutralising antibodies were 52.5 per cent lower than at the height of infection. A King's College study, which has not been reviewed, also stated that nearly 100 out of 4,000 COVID-19 patients didn't recover from the illness three months after they started experiencing symptoms.

"Because COVID-19 is such a new disease, we are only beginning to understand some of its long-term effects on patients' health", said researcher Dr. Bin Cao, from the National Center for Respiratory Medicine at the China-Japan Friendship Hospital and Capital Medical University, both in Beijing.

The breakdown of the most frequent symptoms displayed months later is as follows: fatigue or muscle weakness (63 percent), sleep difficulties (26 percent), and anxiety or depression (23 percent).

As a result, the study authors found about 76 percent of patients who took part in the follow-up, more than 1,200 of the over 1,600 respondents said they still suffer from the symptoms.

About 390 of the study's participants had a lung-function test about six months after they first got COVID-19. But the coronavirus has been found to affect almost every part of the body, and the first sign of your infection can be a pretty obscure one (or you could have no coronavirus symptoms at all).

In all, 1,733 of 2,469 discharged patients with Covid-19 were enrolled after 736 were excluded. Those who had experience severe disease performed worse on this six-minute test.

For patients who required supplemental oxygen therapy and those who did not require oxygen therapy, the researchers said the figures were 29% and 22%, respectively.

The researchers only worked with patients that were hospitalized, as such, experts say, its findings might not apply to the general population of those who have been diagnosed with COVID-19. And he's seen similar issues among patients at his hospital.

Unfortunately, they also said that adding the latest research was consequently relevant and timely as there are few reports on the clinical scenario of the outcome of the pandemic.

Lab tests showed that 13% of patients whose kidneys appeared healthy during their hospital stays had reduced function in the follow-up examination.

"Some persisting symptoms such as fatigue and dyspnea, impaired pulmonary function and chest image abnormalities were reported in patients following hospital discharge, but the full spectrum of post-discharge characteristics is still unknown".
