Idiopathic pulmonary fibrosis (IPF) is characterized by a male predominance. The aim of the study was to explore gender differences in a well-designed French multicentre prospective IPF cohort (COhorte FIbrose, COFI) with a 5-year follow-up. Between 2007 and 2010, 236 patients with incident IPF were included in COFI.

A minority of patients experience acute exacerbations (AEs). A recent study suggested that ozone and nitrogen dioxide might contribute to the occurrence of AE.

The prevalence of CVD and the severity of coronary artery calcification were investigated by high-resolution computed tomography.

Emerging evidence also suggests that "idiopathic" NSIP may be the lung manifestation of undifferentiated CTD (UCTD). However, whether or not NSIP outcome is influenced by the underlying cause remains uncertain.

Respective abundance of circulating endothelial cells (CEC) and endothelial progenitor cells (EPC) might reflect the balance between vascular injury and repair and potentially serve as biomarkers of the disease.
Objectives And Methods: We postulated that CEC and EPC subtypes might be differently modulated in IPF.
Background: In idiopathic pulmonary fibrosis (IPF) the distribution and spatial-temporal progression of fibrotic changes may be influenced by general or locoregional conditions. From this perspective, patients with asymmetrical disease (AIPF) may be unique.
Methods: This retrospective study included 32 patients (26 men, mean ± SD age 69 ± 7 years) with AIPF, as defined by an asymmetry ratio (most affected--least affected fibrosis score)/(most affected + least affected fibrosis score) >0.
The diagnostic of sarcoidosis is done when clinical and radiological usual signs are present with nonnecrotizing granuloma and in the absence of any other granulomatous disease. However, if associated with usual manifestations of sarcoidosis and if published similar case reports are available, diagnostic is not excluded by atypical clinical or radiological facts. Chest thin-section hight-resolution computed tomographic scan is very useful to obvious typical findings when chest-X-ray looks unusual.
