COVID-19, asthma, and biologic therapies: What we need to know

ABSTRACT

Managing patients with severe asthma during the coronavirus pandemic COVID-19 is a challenge. Authorities and physicians are still learning how COVID-19 affects people with underlying diseases, and severe asthma is not an exception. Unless relevant data emerges that changes our understanding of the relative safety of medications indicated in patients with asthma during this pandemic, clinicians must follow the recommendations of current evidence-based guidelines, preventing loss of control and exacerbations. Also, with the absence of data that would indicate any potential harm, current advice is to continue the administration of biologic agents during the COVID-19 pandemic in patients with asthma for whom such agents are clearly indicated and have been effective. For the patients with severe asthma infected by SARS-CoV-2, the decision to maintain or postpone biologic therapy until the patient recovers should be a case-by-case based decision supported by a multidisciplinary team. A registry of cases of COVID-19 in patients with severe asthma, including those treated with biologics, will help to address a clinical challenge where we have more questions than answers.
