Advances in treating acute lung syndromes

@HealthMed Although only described as recently as 1967, a range of important contributory factors have been defined for acute respiratory distress syndrome (ARDS), which is now recognized to be at the severe end of a spectrum of acute lung injury, which imposes high risk for patients and which confers a major burden on health services. Outcome of treating the syndrome has been much improved by developments in devices to treat lung and other organ failure, supported by advances in expertise in intensive care. However, other than treatments for underlying causes, there is still important unmet need with regard to effective specific pharmacological treatments.

A timely review of ARDS by Dushianthan and colleagues is the Editor’s choice article in the September issue of the Postgraduate Medical Journal.  These experts from Southampton provide an update on knowledge of risk factors, including genetic biomarkers, for development of ARDS and other acute lung injury variants, and an up-to-date commentary on general and specific treatment options.

The authors note that ‘sepsis, pneumonia, and trauma with multiple transfusions’ account for most episodes. They highlight the importance for recovery of ‘general supportive measures such as appropriate antimicrobial therapy, early enteral nutrition, prophylaxis against venous thrombo-embolism and gastrointestinal ulceration’.

They discuss encouraging experimental evidence from trials of corticosteroids, nitric oxide, prostacyclins, exogenous surfactants, ketoconazole and antioxidants, however note that these findings have not as yet being translated into benefits for patients. They note as further treatment targets of interest, new approaches to modulating inflammation, and use of mesenchymal stem cells.
