COVID-19 and Asthma, Allergy and Immune Deficiency Patients

ACAAI Statement:

The recent pandemic outbreak of Coronavirus has created much uncertainty and anxiety among many of our patients. Elderly patients, as well as patients with severe asthma, immunodeficiency and other chronic conditions where their immune system may be compromised, are most susceptible to increased morbidity and mortality from viral infections in general, and we assume similar precautions should be recommended to these individuals for Coronavirus.

We recommend all patients especially those with asthma, to remain on their medications. Specifically, asthma patients taking inhaled corticosteroids (ICS) should continue these medications as they have been shown to prevent or reduce asthma exacerbations in part by reducing ICAM-1 levels and/or acidic endosomes important for modulating airway inflammation associated with viral infections.

A recent study reported that ICS inhibit the Coronavirus strain, HCoV-229E, replication partly by inhibiting receptor expression and/or endosomal function thereby modulating infection-induced airway inflammation.  To date 80% of cases are mild and self-limited, manifesting as fever, cough and shortness of breath.

Patients with severe asthma currently on a biologic therapy, there is no information at this time that these treatments should be stopped. We assume they are at increased risk of severe illness if they catch COVID-19 infection and optimal control of their chronic condition is of utmost importance.

Detailed clinical investigation of 140 hospitalized COVID-19 cases in Wuhan China suggests eosinopenia (low eosinophil count) together with lymphopenia (low lymphocyte count) may be a potential indicator for diagnosis. Allergic diseases, asthma, and COPD were not risk factors for COVID-19 infection. The authors found that older age, high number of comorbidities, and more prominent laboratory abnormalities were associated with severe patients.

A joint statement on the current epidemics of new Coronavirus by the world's different primary immunodeficiency organizations has been published. Their recommendations for patients with primary immunodeficiencies (PID) state that there is currently no data pointing to whether PID patients are actually at higher risk of more severe disease from COVID-19. However, it is believed that PID patients might be at higher risk for this infection or a more severe course of the disease. Thus, patients with PID need to take extra care to prevent from getting this infection. Please go to the following link for more information:

Reasonable health care recommendations for asthma and immunedeficiency patients are:

-Avoid close contact (6 feet) with people who are sick.
-Avoid touching your eyes, nose, and mouth.
-Wash your hands often with soap and water for at least 20 seconds.
-Use an alcohol-based hand sanitizer that contains at least 60% alcohol if soap and water are not available.
-Use tissues to cover coughs and sneezes, then discard tissue in the trash.
-Clean/disinfect frequently touched objects and surfaces.
