Background: Most patients with idiopathic pulmonary fibrosis (IPF) complain of cough. IPF-associated cough is widely characterized as dry or non-productive. The aim of this study was to compare chronic cough in early stage IPF patients to cough in subjects with chronic cough from a community-based sample and, especially, to investigate whether cough in IPF is less productive than chronic cough in a community-based sample. Methods: The IPF cough population consisted of 46 biopsy-confirmed patients who complained of chronic cough. Control population consisted of subjects with chronic cough, gathered by a community-based email survey sent to public service employees and the Finnish Pensioners’ Federation. A case-control setting was applied by having four age, gender, and smoking-status matched subjects from the community sample for each IPF cough patient. A cough specific quality of life questionnaire (Leicester Cough Questionnaire (LCQ)) was filled in by all subjects. The LCQ questionnaire contains 19 questions, each question is scored from 1 to 7 and total score from 3 to 21 with a smaller value indicating more severe impairment. Results: The sputum production frequency, as assessed by LCQ question 2, was 5.0 (3.0-6.0) in the IPF chronic cough population and 5.0 (3.0–6.0) in the community-based chronic cough population (median and interquartile range p= 0.72). The LCQ total score was 14.8 (11.5-18.1) in the IPF chronic cough population and 15.4 (13.0–17.5) in the community-based chronic cough population (p=0.76). The domain impact scores were physical, 4.9 (3.9–6.1) vs. 5.1 (4.5–5.6) (p=0.80); psychological, 4.6 (3.7–5.9) vs. 4.7 (3.9–5.7) (p=0.90); and social, 5.5 (3.7–6.5) vs. 5.5 (4.5–6.3) (p=0.84), respectively. Furthermore, cough response to paint or fumes, cough disturbing sleep, and cough frequency per day did not differ between the groups. Conclusion: Cough in early stage IPF patients was not distinguishable from chronic cough in the community-based

Multidisciplinary meeting (MDM) is a core element in the diagnosis of interstitial lung diseases (ILD). The aim of the study was to investigate the implementation and key elements related to ILD MDMs in Finnish specialized care, which is characterized by long travel distances and a large number of small centers treating patients suffering from ILDs. An electronic questionnaire was sent to ILD experts working at five academic centers of Finland regarding the implementation of ILD MDMs with the focus on utilization of virtual communication. Responses were received from all academic centers of Finland (n = 5) whose catchment areas cover all of Finland. ILD MDMs were organized in each center approximately every two weeks and the core participants included a radiologist, respiratory physicians, junior staff, pathologist and a rheumatologist. All non-academic centers could refer their patients to be evaluated in ILD MDM of an academic center. Virtual communication was utilized by all academic centers in the implementation of ILD MDMs, being most common among small centers located in Eastern and Northern Finland. Virtual access to ILD MDM of an academic center was available in most parts of Finland, enabling small centers to benefit from the ILD expertise of academic centers.

Background: The use of a transbronchial lung cryobiopsy (TBLC) is increasing as a diagnostic method of interstitial lung diseases (ILD). This study aimed to evaluate risk factors associated with clinically significant complications of TBLC in ILD patients. Methods: Patients referred to Kuopio or Tampere university hospitals, in Finland, for a suspected ILD were included. The TBLC was performed in an outpatient setting for 100 patients. Patients were mechanically ventilated in general anesthesia. Fluoroscopy guidance and prophylactic bronchial balloon were used. Complications, such as bleeding, pneumothorax, infections, and mortality were recorded. Moderate or serious bleeding, pneumothorax, or death ≤90 days were defined as clinically significant complications. A multivariable model was created to assess clinically significant complications. Results: The extent of traction bronchiectasis (Odds ratio [OR] 1.30, Confidence interval [CI] 1.03–1.65, p = 0.027) and young age (OR 7.96, CI 2.32–27.3, p = 0.001) were associated with the risk of clinically significant complications whereas the use of oral corticosteroids ≤30 days before the TBLC (OR 3.65, CI 0.911–14.6, p = 0.068) did not quite reach statistical significance. A history of serious cough was associated with the risk of pneumothorax (OR 4.18, CI 1.10–16.0, p = 0.036). Procedure associated mortality ≤90 days was 1%. Conclusions: The extent of traction bronchiectasis on HRCT and young age were associated with the risk of clinically significant complications whereas oral corticosteroid use did not quite reach statistical significance. A history of serious cough was associated with the risk of clinically significant pneumothorax.

Background: The disease course of idiopathic pulmonary fibrosis (IPF) is progressive and occasionally, other types of interstitial lung disease (ILD) may progress similarly to IPF. This study aimed to evaluate risk factors for disease progression within 24 months in patients with various ILDs. Methods: This prospective study obtained 97 patients with a suspected ILD who underwent a transbronchial lung cryobiopsy. The extent of several high-resolution computed tomography (HRCT) patterns was assessed. Due to the inclusion criteria the study population presented a low extent of honeycombing and definite usual interstitial pneumonia (UIP) pattern on HRCT suggesting an early stage of ILD. Disease progression within 24 months despite treatment was defined as a relative decline of ≥ 10% in forced vital capacity (FVC), or a relative decline in FVC of ≥ 5% and one of the three additional criteria: (1) a decline in diffusion capacity to carbon monoxide (DLCO) ≥ 15%; (2) increased fibrosis on HRCT; (3) progressive symptoms, or progressive symptoms and increased fibrosis on HRCT. The same definition was utilized in patients with IPF and other ILDs. Risk factors for disease progression were evaluated in a multivariable logistic regression model. Results: Disease progression was revealed in 52% of the patients with ILD, 51% of the patients with IPF, and 53% of the patients with other types of ILD. A high extent of reticulation on HRCT (Odds ratio [OR] 3.11, 95% Confidence interval [CI] 1.21–7.98, P = 0.019) and never smoking (OR 3.11, CI 1.12–8.63, P = 0.029) were associated with disease progression whereas platelet count (OR 2.06 per 100 units increase, CI 0.96–4.45, P = 0.065) did not quite reach statistical significance. Conclusion: Higher extent of reticulation on HRCT and never smoking appeared to associate with the risk of disease progression within 24 months in ILD patients without honeycombing. Approximately half of the patients with ILD revealed disease progress
