In a study just published in The Journal of Allergy and Clinical Immunology: In Practice, researchers from the US looked at data on over 60,000 patients with asthma, some with active asthma, some with well-controlled asthma, and some with asthma that had become COPD, and they concluded with some good news for those with well-controlled asthma, namely that “individuals with well-controlled asthma have less severe COVID-19 outcomes than those with uncontrolled asthma.”
Or, if you look at it from the other end, “patients with active asthma had significantly higher odds of hospitalization, a need for intensive respiratory support (IRS), and ICU admission within 30 days of COVID-19 diagnosis compared to those with inactive asthma, or those with no history of asthma or COPD”.
Although happily, the researchers did not detect a higher death rate within 60 days for those people who had active asthma.
Why the difference in severity between the two groups?
Most likely, the authors speculate, because the “control” meds such as the steroid sprays that most asthmatics have to take to control their asthma lowers the risk of severe infection.
Bottom line: If you have asthma, take your meds.
