Having allergies does not increase the chances of a person to be infected with the coronavirus disease 2019 (Covid-19), according to a study of hospitalized patients who had Covid-19 in the United States.

The findings were scheduled to be presented to the American College of Allergy, Asthma and Immunology, or ACAAI.

“We examined the charts of 275 patients admitted to the hospital who tested positive for [Covid-19] for any history of allergic disease,” said lead author Dr. Dylan Timberlake, an allergist from Ohio State University Wexner Medical Center.
“Over the two-month period when we examined the charts, we found the severity of disease didn’t seem to differ between Covid-19 patients with allergies, versus Covid-19 patients without allergies,” he said in an ACAAI news release.

Factors researchers considered to determine severity of disease included admission to the intensive care unit, length of stay, supplemental oxygen needs and intubation.

The study looked at outcomes for people with allergic rhinitis, asthma, eczema and food allergies. There were no significant differences in the number of interventions those patients needed compared to other patients, researchers found.

“With regard to ICU (intensive care unit) admission, 43 percent of those with allergic disease were admitted versus 45 percent without. And 79 percent of those with allergy needed supplemental oxygen versus 74 percent of those without,” said study co-author Dr. Mitchell Grayson, division chief of allergy and immunology at Nationwide Children’s Hospital in Columbus, Ohio.

In the study, more patients with allergies had chronic obstructive pulmonary disease (COPD), a known risk factor for severe Covid-19.

After adjusting for the presence of COPD, researchers identified a trend suggesting possible protection in patients with preexisting allergic disease but not asthma.Research presented at meetings is typically considered preliminary until published in a peer-reviewed journal. SOVEREIGNPH WITH UPI
