A better understanding of the pathogenesis and the resolution of the acute
respiratory distress syndrome (ARDS) is needed. Although some progress has been
made with the use of protein biomarkers and candidate gene studies in
understanding the pathobiology of ARDS, we propose that new studies that measure
the chemical breakdown products of cellular metabolism (metabolomics) may provide
new insights into ARDS, in part because metabolomics targets a later point in the
genomics cascade than is possible with studies of DNA, RNA, and protein
biomarkers. Technological advances have made large-scale metabolomic profiling
increasingly feasible. Metabolomic approaches have already achieved novel
insights in nonpulmonary diseases such as diabetes mellitus and malignancy, as
well as in sepsis, a major risk factor for developing ARDS. Metabolomic profiling
is a promising approach to identify novel pathways in both patients at risk for
developing ARDS as well as in the early phase of established ARDS.
