Asthma may not raise the risk of extreme COVID-19

A recent review of research suggests that the proportion of most patients hospitalized with COVID-19 who likewise have asthma is comparable to the prevalence of asthma in the wider population.

In their latest advice, the Centers for Disease Control and Avoidance (CDC) warn that persons with moderate-to-severe asthma could be at greater threat of developing severe COVID-19.

However, a review of research simply by scientists at the University of Colorado in Denver features found no proof an elevated prevalence of asthma among patients hospitalized with COVID-19 weighed against the condition’s prevalence in the larger population.

In addition, they discovered that patients hospitalized with COVID-19 who had asthma were forget about apt to be intubated than other patients.

“The CDC [place] persons with asthma at higher risk [of] COVID-related hospitalization,” says senior author Dr. Fernando Holguin. “However, various international studies also show low numbers of [asthmatic persons] among hospitalized COVID-19 patients. These findings obstacle the assumption about asthma as a risk component.”

In a study letter that appears in the history of the American Thoracic Society, the authors report:

“Despite early concern about disproportionately excessive morbidity and mortality for those with asthma, info presented here and somewhere else show minimal proof a clinically significant relationship.”

Comparison of prevalence

Because of their analysis, the researchers recognized 15 studies published in English before May 7, 2020, that reported on asthma prevalence among patients hospitalized with COVID-19. The studies took place in Brazil, China, the Republic of Korea, the United Kingdom, and america.

If they compared these statistics with the prevalence of asthma in each individual population, the quantities were broadly similar.

Although the prevalence of asthma among hospitalized COVID-19 patients varied widely from study to review, the overall prevalence was around 7%.

By contrast, the authors discovered that persons with asthma accounted for a lot more than 20% of most those hospitalized with influenza in the U.S.

Finally, they looked at whether patients admitted to the University of Colorado Hospital with COVID-19 had been much more likely to be intubated if they had asthma. After adjusting for the patients’ age group, sex, and human body mass index (BMI), they found no evidence that was the case.

To conclude, they write:

“Since there is variable asthma prevalence among COVID-19 published analyses, it appears comparable to population prevalence, and certainly much lower than what would be expected during seasonal flu. The results of this study recommend that asthma will not appear to be a significant risk component for developing severe COVID-19 needing hospitalization or intubation.”
