The most frequent symptom was fatigue or muscle weakness, detected in 63% of patients, followed by difficulties in falling asleep —26% —and anxiety or depression —23% —according to the data.

Most hospitalized patients with covid-19 present at least one symptom, such as fatigue, six months after overcoming the disease, according to an article published this Friday in the medical journal The Lancet.

The study, developed by a team of Chinese researchers, analyzes the long-term effects of covid-19 in patients admitted to the Jin Yin-tan hospital in Wuhan, a Chinese town where the first coronavirus outbreak emerged at the end of 2019.

The results confirm that 76% of a total of 1,733 patients, who were discharged between January and May 2020, still had some effect of covid-19 half a year later, between June and September.

The most frequent symptom was fatigue or muscle weakness, detected in 63% of patients, followed by difficulties in falling asleep —26% —and anxiety or depression —23% —according to the data.

The investigation also reveals that those hospitalized patients in a more serious condition tended to suffer six months later a greater deterioration in their lung function and abnormalities in chest imaging tests, which could indicate persistent damage to some organs.

On the other hand, the level of antibodies was reduced by more than half – 52.5% – in a hundred patients whose immune system was evaluated during the infection, a figure that sheds light on the risk of being infected again but that should be interpreted with caution given the need to expand the sample in future studies, according to experts.

The research, one of the few that exists to date on the long-term effects of COVID-19, the authors note, followed patients for an average of 186 days after they contracted the disease.

Given the evidence of persistent symptoms, the article stresses “the need to provide medical attention after discharge, particularly for those who experience serious infections,” explains author Bin Cao, from the National Center for Respiratory Medicine, in a statement. China-Japan Friendship Hospital and Capital Medical University (CMU).

“Our work also highlights the importance of carrying out longer follow-up studies in larger populations to understand the full spectrum of effects that COVID-19 can have on people,” says the scientist.

Along the same lines, a group of Italian scientists, external to the study, is expressed, who highlights the importance of delving into the analysis of patients admitted to the ICU, a group that represents only 4% of the participants in the research.

The study included a series of face-to-face interviews with all patients, with an average age of 57, who also underwent medical examinations, a six-minute walk endurance test and laboratory tests.

The latter also showed that some survivors of covid-19 developed kidney problems after being discharged from hospital.

La investigación ha contado con un equipo de expertos encabezado por Chaolin Huang, Lixue Huang, Yeming Wang, Xia Li, Lili Ren, Xiaoying Gu, Liang Kang, Li Guo y Min Liu.
