Idiopathic interstitial diseases
" Test group ": patients suffering from idiopathic interstitial lung diseases including sarcoidosis and idiopathic pulmonary fibrosis. Nanoparticles (NP) loads will be measured on Bronchoalveolar lavages (BAL), bronchial washings (BW), exhaled air condensates (EAC), blood specimen and urine specimen. |

NP load
Délai: day 1
|
The load of NP is a composite outcome. It will be described according to their level of presence (high, moderate or low), their size and chemical analysis. Analysis: The presence of NP will be assessed by dynamic light scattering (DLS). The elemental compositions of both the particulate (pellet) and the soluble (supernatant) fractions of each sample will be measured by means of inductively coupled plasma optical emission spectroscopy (ICP-OES). The samples for which DLS and ICP-OES corroborated a relatively stronger NP load will be observed under transmission electron microscopy (TEM) and field-emission electron microscopy (FESEM). |

Correlation between NP load in the lung and observed lung interstitial diseases
Délai: Day 1
|
The load of NP is a composite outcome. It will be described according to their level of presence (high, moderate or low), their size and chemical analysis. The accurate diagnosis of the disease will be determined in accordance to the latest international guidelines, including the past history of each patient, the professional courses with focus on potential NP exposure, environmental studies, tobacco or drug use and exhaustive research of collagen or vascular diseases. |
