France found that asthma will not add to re-coronary pneumonia
Science and Technology Daily, Paris, August 12 (Reporter Li Hongce) Researchers from the Paris Public Hospital Group (AP-HP) and the University of Paris-Saclay conducted a study on patients hospitalized with new coronary pneumonia and showed that asthma patients were infected with new coronary pneumonia After that, there is no risk of getting worse. The results of this study were recently published in the journal European Journal of Respiration.
Respiratory virus infection (rhinovirus, respiratory syncytial virus, influenza virus, etc.) is the main cause of exacerbation of asthma, and may also be related to the acute attack of asthma patients. Asthma patients are also susceptible to respiratory viruses. Before the emergence of the new coronavirus, a review published in 2018 suggested that when asthma symptoms worsen, the detection rate of coronavirus in respiratory specimens ranges from 8.4% in children to 20.8% in adults. This makes the virus the second most common virus in adults after rhinovirus.
The sudden new coronary pneumonia pandemic characterized by severe pneumonia has caused people to worry that asthma patients are at an increased risk of contracting the new coronavirus, accompanied by severe lung disease or an increase in asthma. However, the strange thing is that in some of the first published articles about new coronary pneumonia, whether in China, Italy or the United States, the proportion of asthma patients suffering from new coronary pneumonia does not seem to be high.
This time, the researchers conducted observational studies on the clinical characteristics and development of asthma patients hospitalized with new coronary pneumonia in the Bissett Hospital in the spring of 2020. Among the 768 patients who were hospitalized between March 15 and April 15, 37 (4.8%) were asthmatic, which is roughly similar to the French general population of the same age. This shows that among hospitalized patients with severe lung disease infected by the new coronavirus, the proportion of asthma patients is not high; compared with the general population, the death rate of asthma patients infected with new coronary pneumonia has not increased.
None of these patients had severe asthma attacks when they were admitted to the hospital, so no special treatment measures were taken for them. During the hospital stay, no special measures were taken to treat asthma symptoms. The researchers also pointed out that patients with asthma who were infected by the new coronavirus did not experience adverse reactions during the continuous treatment of asthma.
The researchers next plan to verify whether drugs used to treat asthma are effective against new coronary pneumonia.
