Discover the causes of idiopathic pulmonary fibrosis

31 10 2013

Researchers from the Vall D'hebron University Hospital and the Group of Pneumology of the Vall D'hebron Research Institute (VHIR) they have shown that causes of pulmonary fibrosis idiopathic in half of the cases can be determined following the completion of a clinical study in depth, that includes an exhaustive and systematic interrogation, determination of antibodies against the causative substances, inhalation tests, crops and environmental measurements where the patient attends (home and work) to detect antigens that may cause this serious disease.

The importance of this trial, made with patients from the outpatient service of Pneumology Hospital, It is showing that assisted a systematized and in depth and with techniques appropriate, advances for our health care system can also be”, says Dr. Ferran Morell, the study's lead author.


The study, published in The Lancet Respiratory Medicine, was conducted between 2004 and 2011 in 60 patients with this disease and it will open a new Avenue in the diagnosis and treatment of this pathology, Since the identification of the causes will prevent this disease and this will prevent disease to evolve towards advanced or severe phases.


Researchers have found that one of the main causes of idiopathic pulmonary fibrosis is exposure to quilts and cushions of feathers, as well as exposure to birds and fungi in minimal but persistent amounts. In short, It's the disease called chronic Hypersensitivity Pneumonitis, disease in which the Hospital Universitari Vall D'hebron is world reference.

To be able to timely diagnose this pathology, Dr. Ferran Morell ensures that “is essential for the diagnosis of the patients study have ready the techniques for the detection of antibodies against the causative substances and inhalation tests (broncoprovocacion), as well as the realization of soluble extracts from substances, etc.”.


Idiopathic pulmonary fibrosis is a recognized disease from 1940, in which both lungs gradually is fibrosan (heal); Like this, the lung loses elasticity, making it difficult to inspiration, gradually losing the patient breathing capacity. This disease affects one 10.000 patients in Spain (2.000 in Catalonia) and has an incidence of between 10 and 20 new cases for each 100.000 inhabitants per year.
