Idiopathic pulmonary fibrosis (IPF), the etiopathogeny of which is still unknown, is the most frequent and severe of idiopathic interstitial pneumonias. It progressively leads, sometimes more acutely when exacerbations occur, to a restrictive respiratory insufficiency. Its prognosis is very dark with a median survival of 3-5 years. No treatment so far has been curative. Its diagnostic and therapeutic management has been greatly improved due to the technical progress in terms of high-resolution tomodensitometry, to the availability of new drugs with a real antifibrotic potential and to the production of international recommendations. The diagnosis is reached in 2/3 of IPF patients presenting with a typical usual interstitial pneumonitis (UIP) CT-scan pattern. It requires a videothoracoscopic biopsy in the remaining patients. Multidisciplinary discussions are key to a proper diagnosis of IPF. Pirfenidone is presently the only drug with a real antifibrotic potential in mild to moderate forms of the disease (FVC>50% and DLCO>35% predicted). The other ones have proved either inefficient or toxic. It is highly recommended to include patients in innovative targeted protocols. Non-pharmacological management of these patients comprises long-term oxygen therapy, pulmonary rehabilitation and overall lung transplantation. Pulmonary hypertension, to be detected regularly during the follow-up, is associated to a dark prognosis. No specific treatment is efficient in this context. Several comorbidities, particularly frequent in IPF, should be treated when present: gastro-oesophageal reflux, obstructive sleep apnea, emphysema. The particular high frequency of bronchopulmonary cancer should be highlighted.

Background Currently, only two drugs have been shown to modify the inevitable natural history of idiopathic pulmonary fibrosis (IPF). Changes in the reimbursement policy for antifibrotic drugs in Poland have led to the availability of pirfenidone from January 2017 and nintedanib from March 2018 for the treatment of Polish patients with IPF. This study aimed to evaluate the possible changes and shortcomings in the clinical practice standards in IPF in the era of access to antifibrotic therapy in Poland. Methods A real-world data survey was performed among physicians attending the Polish Respiratory Society Congress held in May 2018. The present survey was a follow-up to the previous survey undertaken in 2016, before the availability of antifibrotics in Poland. Results A total of 99 physicians participated in the survey, among which 80% were pulmonologists. The majority of participants (83%) represented hospital-based clinicians and most of them (93%) were involved in interstitial lung diseases (ILD) management. As many as 63% of the respondents elaborate the final diagnosis of IPF working with the expert radiologist routinely, 47% do that in the cooperation with other pulmonologists, and if a biopsy was performed 39% discuss its results with the expert pathologist. Bronchoalveolar lavage (BAL) and surgical lung biopsy (SLB) would never be recommended in the differential diagnosis of IPF by 9% and 16% of the respondents, respectively. Corticosteroids (CS) or a combination of CS and immunosuppressants (IS) is still recommended by 22% of participants. Proton pump inhibitors (PPI) in the case of symptomatic GERD are prescribed by 44% of the respondents, and 12% prescribe PPI regardless of GERD symptoms. Pirfenidone is used by 70%, and nintedanib by 48% of the respondents. Only 39% of the respondents refer patients with IPF to professional rehabilitation centers. Conclusions The level of cooperation between pulmonologists and other specialists in the diagnostic workup of IPF is unsatisfactory. IPF treatment practices in the era of access to effective drugs in Poland require immediate improvement. There is an urgent need to develop the local Polish practical guidelines to improve the management of IPF.
