The effects of dexamethasone (DXM) treatment on pulmonary immunity in COVID-19 associated acute respiratory distress syndrome (CARDS) remain insufficiently understood. We performed transcriptomic RNA-seq analysis of bronchoalveolar lavage fluid from 20 mechanically ventilated patients: 12 with CARDS (DXM+ or DXM-) and 8 non-COVID-19 critically ill controls. CARDS (+DXM) was characterized by upregulation of genes related to B-cell and complement pathway activation, antigen presentation, phagocytosis and FC-gamma receptor signalling. Most ISGs were upregulated in CARDS, particularly in CARDS (-DXM). In conclusion, DXM treatment was not associated with regulation of pro-inflammatory pathways in CARDS but with regulation of other local immune responses.
