Principaux critères d’inclusion: Age 18 years
A diagnosis of ILD: ILD associated with differentiated CTD or IPAF (based on internationally accepted criteria)OR idiopathic ILDA diagnosis of NSIP based on: a histological pattern of NSIP
OR HRCT findings suggestive of NSIP defined as basal predominant reticular abnormalities with traction bronchiectasis, peri-bronchovascular extension and subpleural sparing, frequently associated with ground-glass attenuation
Patients who did not respond or relapsed or were not able to continue at least one first-line immunosuppressive treatment of ILD: corticosteroids, azathioprine, cyclophosphamide or other immunosuppressants. For the assessment of clinical response, the absence of response was defined as: either a decrease or an increase, but <10% in % predicted FVC.
