Acute Respiratory Distress Network (ARDSNet) Study 02 Late Steroid Rescue Study (LaSRS) (ARDSNet-LaSRS-BioLINCC)

Data Access NOTE: Please refer to the “Authorized Access” section below for information about how access to the data from this accession differs from many other dbGaP accessions.

Biospecimens: Access to Biospecimens is through the NHLBI Biologic Specimen and Data Repository Information Coordinating Center (BioLINCC). Biospecimens from ARDSNet-LaSRS include BAL Slides, Bronchial Lavage, and Plasma. Please note that use of biospecimens in genetic research is subject to a tiered consent.

Objectives: Since previous reports suggested that corticosteroids may improve survival, this project was developed as a multicenter, randomized controlled trial of corticosteroids in patients with persistent ARDS.

Background: Persistent acute respiratory distress syndrome (ARDS) is characterized by excessive fibroproliferation, ongoing inflammation, prolonged mechanical ventilation, and a substantial risk of death.

Participants: There were 180 participants.

Conclusions: The results do not support the routine use of methylprednisolone for persistent ARDS despite the improvement in cardiopulmonary physiology. In addition, starting methylprednisolone therapy more than two weeks after the onset of ARDS may increase the risk of death. (NEJM April 20, 2006; Vol 354, No. 16, pp 1671-84).
