PURPOSE: Conclusive data on whether inhaled corticosteroids (ICS) have a protective effect on COVID-19 hospitalization rates or outcomes are lacking. The main objective of our study was to assess the impact of pre-hospitalization ICS use on the clinical course of hospitalized COVID-19 patients with underlying obstructive lung diseases - asthma and chronic obstructive pulmonary disease (COPD).
METHODS: We conducted a retrospective chart review study of all COVID-19 patients hospitalized at our institution between March 1st - June 3th, 2020. Diagnosis of asthma and COPD was determined using ICD-10 codes. Demographics, information about pre-hospitalization ICS use and clinical data were recorded through chart review. Outcomes of interest were all-cause 28-day mortality and need for intubation. Chi-square or Fischer’s exact test was used to assess univariate associations. Linear and logistic regression models were constructed to adjust for potential confounders.
RESULTS: Data was analyzed from 356 hospitalized COVID-19 patients with prior diagnosis of obstructive lung disease; 219/356 (62%) had asthma, 137/356 (38%) had COPD. Hospitalized COVID-19 patients with asthma were younger (mean age 61 [range: 51-71] vs 74 [range:67-81] years, p<0.01), more likely to be female (69% vs 48%, p<0.01), Hispanic (43% vs 25%, p<0.01) and never smokers (52% vs 20%, p<0.01) compared to those with COPD. There was no difference in the use of pre-hospitalization ICS between the two groups (35.2% in Asthma vs 38% in COPD, p=0.59). Overall, COVID-19 patients with COPD were more likely to die compared to those with asthma (47% vs 25%, p<0.01). Pre-hospitalization ICS use was not significantly associated with all-cause 28-day mortality (asthma: OR 0.9 [95%CI 0.4-2.0], p=0.85; COPD: OR 0.7 [95%CI 0.3-1.5], p=0.3) or need for intubation (asthma: OR 1.0 [95%CI 0.5-2.0], p=0.94; COPD: OR 0.7 [95%CI 0.3-1.7],p=041) after adjusting for potential confounders.
CONCLUSIONS: Mortality among hospitalized COVID-19 patients with COPD was higher compared to those with asthma. While the pre-hospitalization use of ICS was similar between the two groups, it did not protect hospitalized COVID-19 patients in either group from intubation or mortality. High mortality rates among COVID-19 patients with COPD is likely due to concomitant risk factors such as older age, and comorbidities such as diabetes and chronic kidney disease. Being a retrospective study, the quality of our data was limited and dependent on documentation accuracy.
CLINICAL IMPLICATIONS: Pre-hospitalization ICS use did not improve outcomes in hospitalized COVID-19 patients with asthma or COPD. Further studies are required to investigate the role of ICS in preventing COVID-19 related hospitalizations, morbidity and mortality in randomized control settings.
