“…We recently reviewed the data of 30 patients suffering of idiopathic pulmonary fibrosis (IPF; n= 22) or idiopathic non-specific interstitial pneumonia (NSIP; n=18), according to the international consensus statement, admitted in our intensive care unit (ICU) for acute respiratory failure (ARF) between 01/01/1999 and 31/12/2009 (Table 1). We chose to associate the two patterns in the same study because IPF and NSIP closely mimic each other clinically, despite the fact that some authors believe that they should remain separate (3,4). Among 30 patients, 15 (50%) were hospitalized in ICU for acute exacerbation (AE), 9 (30%) for pulmonary infection and 6 (20%) for miscellaneous causes.…”
