Background: A high percentage of critically ill polytrauma patients develop acute respiratory distress syndrome (ARDS), both because of the primary traumatic injuries and because of the secondary post-traumatic injuries. For adequate management of these patients, new complex evaluation and monitoring methods are needed, methods that could answer as many questions as possible regarding the pathophysiological changes associated with ARDS. Currently, a series of clinical and biochemical markers are being used which unfortunately do not respond to the needs of an intensive care clinician. Therefore, the changes of miRNAs have been intensely researched in the case of patients with ARDS. Moreover, using them as biomarkers for ARDS brings a series of answers regarding the pathophysiological changes associated to ARDS, making them biomarkers of the future in laboratory medicine.
Methods: In order for this research study to be carried out the literature found on Scopus and PubMed on the topic was consulted, up to the year 2015. The key words used for the articles were “acute respiratory distress syndrome ARDS”, “biomarkers for ARDS”, “critically ill polytrauma patients”, ”miRNAs expression in ARDS”, ”miRNAs expression in sepsis”, ”miRNAs in critically ill patients” and ”miRNAs biomarker”. Research articles in English, German, and French were included in the search.
Results: Following the search using the above mentioned key words, 567 articles were found. After a rigorous analysis of these articles 55 of them were selected for our study.
Conclusions: Using miRNAs for the evaluation and monitoring of ARDS makes them a biomarker of the future, because of the complex answers they bring to questions related both to the main injury caused by ARDS and to the associated pathophysiology.
