The Impact of Prior Corticosteroid Use in COPD and Asthma on COVID-19 Mortality

Corticosteroid exposure

Corticosteroids are a class of medications commonly used to treat inflammation and immune-related conditions such as chronic obstructive pulmonary disease (COPD) and asthma. These medications work by reducing inflammation, swelling, and immune responses in the body. However, the use of corticosteroids has raised concerns regarding their potential impact on COVID-19 mortality rates in patients with pre-existing respiratory conditions. This article will explore the relationship between prior corticosteroid use in COPD and asthma patients and their susceptibility to severe COVID-19 outcomes.

The Link Between Corticosteroid Use and COVID-19 Mortality

The COVID-19 pandemic has highlighted the importance of understanding the factors that may contribute to severe outcomes in infected individuals. One area of interest is the impact of prior corticosteroid use on COVID-19 mortality. Corticosteroids are effective in suppressing the immune system and reducing inflammation, making them useful in managing conditions like COPD and asthma. However, this suppression of immune responses can increase the vulnerability of the individual to respiratory infections such as COVID-19.

Several studies have examined the association between corticosteroid exposure and COVID-19 mortality rates. One study conducted by researchers at the University of Oxford analyzed data from over 8,000 patients with COPD or asthma who tested positive for COVID-19. The results showed that individuals with a history of corticosteroid use had an increased risk of mortality compared to those who had not been exposed to these medications. The study concluded that prior corticosteroid use can be a significant predictor of adverse COVID-19 outcomes in patients with respiratory conditions.

Understanding the Mechanisms

The exact reasons behind the increased susceptibility to severe COVID-19 outcomes in individuals with prior corticosteroid use are not fully understood. However, there are several possible mechanisms that researchers have proposed. Firstly, corticosteroids can suppress the immune system, impairing the body’s ability to fight off infections effectively. This weakened immune response can result in a more aggressive course of COVID-19 and a higher risk of mortality.

Secondly, corticosteroids can also have a detrimental effect on lung function. These medications can cause the thinning of the lining of the airways and impair the clearance of mucus, making individuals more susceptible to respiratory infections. When combined with COVID-19, which primarily affects the respiratory system, this impaired lung function can lead to more severe and potentially fatal outcomes.

Frequently Asked Questions

1. Should individuals with COPD and asthma stop taking corticosteroids during the COVID-19 pandemic?

It is crucial to consult with a healthcare professional before making any changes to medication regimens. Abruptly stopping corticosteroids can have adverse effects on individuals with COPD and asthma and may lead to exacerbation of symptoms. Healthcare providers will assess the benefits and risks of corticosteroid use in each individual case and provide appropriate guidance.

2. Are there alternative medications for managing inflammation in COPD and asthma?

There are alternative medications available for managing inflammation in COPD and asthma. These include bronchodilators, anticholinergic agents, and leukotriene modifiers. Healthcare providers will determine the most suitable treatment plan based on the individual’s condition and needs.

3. What measures can individuals taking corticosteroids for COPD and asthma take to reduce the risk of COVID-19?

Individuals taking corticosteroids for COPD and asthma should adhere to recommended preventive measures, including practicing good hand hygiene, wearing masks in public settings, maintaining social distancing, and getting vaccinated against COVID-19. It is also essential to continue following the prescribed treatment regimen and regularly communicate with healthcare providers for any concerns or changes in symptoms.


Prior corticosteroid use in individuals with COPD and asthma has been associated with an increased risk of severe outcomes in COVID-19 infections. The suppression of the immune system and potential lung function impairment can contribute to higher mortality rates. However, it is important to note that corticosteroid use is often necessary for managing chronic respiratory conditions. Healthcare providers play a crucial role in assessing the risks and benefits of continuing or adjusting corticosteroid use in light of the ongoing pandemic. Individuals should consult with their healthcare providers for personalized guidance and adhere to recommended preventive measures to reduce the risk of COVID-19.[4]
