22 It is well known that GCs inhibit the mRNA transcription of proinflammatory genes, which may be significant to reducing neutrophilic inflammation due to evidence that lung-transmigrated neutrophils exhibit a rapid burst of inflammatory transcription on arrival in the airspace. 137 However, GCs have generally failed to show efficacy in ALI/ARDS in human clinical studies. 138 Indeed, the influence of GCs in infection-induced acute injury appears pathogen-dependent.
