Immunosuppression in the ARDS due to other infectious pathogensgroup was due to posttransplant status (n = 3), alveolar proteinosis (n = 1),ANCA-MPO vasculitis (n = 1), neoplasms (n = 1) and human immunodeficiency virusinfection (n = 1). This evidence concerns the gene MPO and acute respiratory distress syndrome.
