Combination of BAL and Computed Tomography Differentiates Progressive and Non-progressive Fibrotic Lung Diseases. Am J Respir Crit Care Med 2023; 208:975-982.

Abstract
Rationale: Identifying patients with pulmonary fibrosis (PF) at risk of progression can guide management. Objectives: To explore the utility of combining baseline BAL and computed tomography (CT) in differentiating progressive and nonprogressive PF. Methods: The derivation cohort consisted of incident cases of PF for which BAL was performed as part of a diagnostic workup. A validation cohort was prospectively recruited with identical inclusion criteria. Baseline thoracic CT scans were scored for the extent of fibrosis and usual interstitial pneumonia (UIP) pattern. The BAL lymphocyte proportion was recorded. Annualized FVC decrease of >10% or death within 1 year was used to define disease progression. Multivariable logistic regression identified the determinants of the outcome. The optimum binary thresholds (maximal Wilcoxon rank statistic) at which the extent of fibrosis on CT and the BAL lymphocyte proportion could distinguish disease progression were identified. Measurements and Main Results: BAL lymphocyte proportion, UIP pattern, and fibrosis extent were significantly and independently associated with disease progression in the derivation cohort (n = 240). Binary thresholds for increased BAL lymphocyte proportion and extensive fibrosis were identified as 25% and 20%, respectively. An increased BAL lymphocyte proportion was rare in patients with a UIP pattern (8 of 135; 5.9%) or with extensive fibrosis (7 of 144; 4.9%). In the validation cohort (n = 290), an increased BAL lymphocyte proportion was associated with a significantly lower probability of disease progression in patients with nonextensive fibrosis or a non-UIP pattern. Conclusions: BAL lymphocytosis is rare in patients with extensive fibrosis or a UIP pattern on CT. In patients without a UIP pattern or with limited fibrosis, a BAL lymphocyte proportion of ⩾25% was associated with a lower likelihood of progression.

Abstract
INTRODUCTION Idiopathic pulmonary fibrosis (IPF) is an irreversible fibrosing disease with median survival at diagnosis of 2-5 years. That said, pirfenidone and nintedanib slow down the gradual decline in respiratory function. Clinical trials have shown that while they are not curative, these drugs reduce mortality and increase survival time compared to placebo. This objective of this work was to compare the real-life survival of patients with IPF diagnosed at the Tours University Hospital depending on whether or not they took anti-fibrotic medication. METHODS This is a monocentric retrospective study involving 176 patients diagnosed with IPF starting from 1997. Out of these 176 patients, 100 were treated with anti-fibrotic agents and 76 did not receive any anti-fibrotic treatment. RESULTS Survival significantly increased in the group with anti-fibrotic medication, with median survival of 59 months [46-87] versus 39 months [29-65] (P=0.022). Predictive factors for death were neoplasia, IPF exacerbation and decreased DLCO. CONCLUSION Our study corroborates the beneficial result observed in clinical trials by showing longer survival in patients using anti-fibrotic agents.

Abstract
Diagnosis of interstitial lung diseases (ILD) is difficult to perform. Extracellular vesicles (EVs) facilitate cell-to-cell communication, and they are released by a variety of cells. Our goal aimed to investigate EV markers in bronchoalveolar lavage (BAL) from idiopathic pulmonary fibrosis (IPF), sarcoidosis and hypersensitivity pneumonitis (HP) cohorts. ILD patients followed at Siena, Barcelona and Foggia University Hospitals were enrolled. BAL supernatants were used to isolate the EVs. They were characterized by flow cytometry assay through MACSPlex Exsome KIT. The majority of alveolar EV markers were related to the fibrotic damage. CD56, CD105, CD142, CD31 and CD49e were exclusively expressed by alveolar samples from IPF patients, while HP showed only CD86 and CD24. Some EV markers were common between HP and sarcoidosis (CD11c, CD1c, CD209, CD4, CD40, CD44, CD8). Principal component analysis distinguished the three groups based on EV markers with total variance of 60.08%. This study has demonstrated the validity of the flow cytometric method to phenotype and characterize EV surface markers in BAL samples. The two granulomatous diseases, sarcoidosis and HP, cohorts shared alveolar EV markers not revealed in IPF patients. Our findings demonstrated the viability of the alveolar compartment allowing identification of lung-specific markers for IPF and HP.

Abstract
OBJECTIVES We sought to evaluate the prognostic value of blood routine parameters and biochemical parameters, especially inflammation-related biomarkers, and establish an inflammation-related prognostic model in Chinese patients with idiopathic pulmonary fibrosis (IPF). MATERIAL/METHODS Patients diagnosed as IPF at Beijing Chaoyang Hospital and aged 40 years and older were consecutively enrolled from June 2000 to March 2015, and finally, a total of 377 patients were enrolled in the derivation cohort. The follow-up ended in December 2016. We used Cox proportional hazard model to calculate the hazard ratio (HR) and establish the prognostic model. The discrimination and calibration of the prognostic model were evaluated in an independent validation cohort enrolled from China-Japan Friendship Hospital between January 2015 and December 2019. RESULTS Multivariate analysis revealed that patients with elevated monocyte-to-red blood cell count ratio (MRR) and monocyte counts showed increased risk of mortality. The clinical-physiological-biomarker (CPB) index and CPB stage we established in this study were a significant predictor, and the C-index for CPB index and CPB stage in the validation cohort was 0.635 (95% CI: 0.558-0.712) and 0.619 (95% CI: 0.544-0.694), respectively. Patients in CPB stage III had the poorest survival. CONCLUSION We developed and validated a new inflammation-related prognostic model (CPB index and CPB stage) which was integration of age, gender, FVC (%, predicted), DLCO (%, predicted), Charlson Comorbidity Index, and blood monocyte counts. This prediction model exhibited strong ability in predicting mortality in Chinese patients with IPF.

Abstract
Introduction: Idiopathic pulmonary fibrosis is a chronic progressive fibrotic lung disease of unknown etiology that occurs most commonly in older adults. The presence of pulmonary hypertension in Idiopathic pulmonary fibrosis is associated with poor prognosis and mortality. Literature suggests that the forced vital capacity to diffusion capacity of the lung for carbon monoxide ratio has a positive predictive value for the diagnosis of pulmonary hypertension. Therefore, this study aimed to investigate the impact of forced vital capacity to diffusion capacity of the lung for carbon monoxide ratio on the diagnosis of pulmonary hypertension and disease prognosis in Idiopathic pulmonary fibrosis patients.
MATERIAL AND METHOD: Forty-eight patients diagnosed with Idiopathic pulmonary fibrosis were included in the study. Patient records, echocardiographic and spirometric data were retrospectively reviewed.
Results: The average pulmonary arterial pressure was observed to be 32.8 (±9) mmHg, with the second-year follow-up pulmonary arterial pressure at 40.8 (±17.2) mmHg and the fourth-year follow-up pulmonary arterial pressure at 51 (±23.6) mmHg. In those diagnosed as pulmonary hypertension, the forced vital capacity to diffusion capacity of the lung for carbon monoxide ratio was initially 1.54 (±0.72). By the second year, it was 1.61 (±0.45), and by the fourth year, it was 1.87 (±0.8). It was found that the forced vital capacity to diffusion capacity of the lung for carbon monoxide ratio tended to increase when pulmonary artery pressure increased during the follow-up period.
Conclusion: We found that low six- minute walking test distance was an important marker for the diagnosis of pulmonary hypertension in patients with idiopathic pulmonary fibrosis and that the presence of desaturation was also significantly associated with survival in pulmonary hypertension. Although we did not find it statistically significant, we found that both pulmonary arterial pressure and the the forced vital capacity to diffusion capacity of the lung for carbon monoxide ratio increased with progressive disease duration after diagnosis in patients with IPF. We believe that the the forced vital capacity to diffusion capacity of the lung for carbon monoxide ratio is an important marker for early detection of pulmonary hypertension and prognosis in idiopathic pulmonary fibrosis.

Abstract
Variable patterns of disease progression are typically observed in patients with idiopathic pulmonary fibrosis (IPF). We sought to determine the prognostic capacity of blood cell count indexes, derived from routine complete blood cell (CBC) count, in a cohort of IPF patients. The neutrophil-to-lymphocyte ratio (NLR), derived neutrophil-to-lymphocyte ratio (dNLR), monocyte-to-lymphocyte ratio (MLR), platelet-to-lymphocyte ratio (PLR), systemic inflammation index (SII), systemic inflammation response index (SIRI), and aggregate index of systemic inflammation (AISI) were calculated at baseline in a consecutive series of 82 IPF patients followed for four years. After adjusting for age, gender, body mass index, smoking status, and disease stage, only the AISI was significantly associated with mortality (HR 1.0013, 95% CI 1.0003–1.0023, p = 0.015). Patients with AISI <434 and ≥434 had a median survival from the diagnosis of 35.3 ± 15.2 and 26.6 ± 16.3 months (p = 0.015), and a four-year survival rate of 54% and 34%, respectively. The AISI, easily derivable from routine laboratory tests, is independently associated with mortality in patients with IPF. Prospective studies in larger cohorts are required to confirm this association.

Abstract
BACKGROUND Idiopathic pulmonary fibrosis (IPF) is a progressive lung disease often managed with nintedanib, a tyrosine kinase inhibitor targeting several profibrotic pathways. Although clotting processes are involved in wound healing and repair in the lung, there are no data on the role of antithrombin III (ATIII) in IPF patients treated with nintedanib. A previous proteomic analysis of serum of IPF patients before and after 1 year of nintedanib treatment showed differential protein expression of ATIII. AIMS Here we used quantitative methods to evaluate differential ATIII concentrations in IPF patients before and after 1 year of nintedanib treatment and to assess the potential of ATIII as a prognostic biomarker in IPF patients. METHODS Serum levels of ATIII were measured by enzyme-linked immunosorbent assay in 14 IPF patients before and after 1 year of nintedanib treatment. RESULTS A statistically significant inverse correlation was found between serum ATIII concentrations and pulmonary function test parameters in all patients at baseline and follow up. Baseline serum ATIII and bronchoalveolar lavage (BAL) neutrophils proved to be reliable predictors of poor prognosis. A baseline ATIII threshold of 126.5 μg/mL discriminated survivors from non-survivors. CONCLUSIONS After 12 months of antifibrotic treatment, IPF patients with high serum ATIII concentrations and high BAL neutrophil percentages had a poor prognosis and increased survival risk. The results of this preliminary study suggest that ATIII has potential as a biomarker of IPF severity and in predicting response to nintedanib therapy. As a marker, ATIII showed several advantages over BAL neutrophil percentage.

Abstract
Background: Idiopathic pulmonary fibrosis (IPF) is the most common idiopathic interstitial pneumonia and has a median survival after diagnosis of 2–5 years. Pirfenidone is the first approved antifibrotic drug for the treatment of IPF. Here we report the functional progress, side effects and survival data of a population of patients with IPF, diagnosed at our centre and treated with pirfenidone. Methods: We enrolled 91 patients with IPF (71 males) treated with pirfenidone. Clinical, survival and functional details were collected retrospectively at start of therapy and after 12, 24, 36 and 48 months of treatment. Lung function tests at least 12 months before starting therapy were available for 40 patients and were entered in the database, as well as side effects. Results: During the observation period (922 ± 529 days), 27 patients died, 5 patients underwent lung transplant and 10 patients interrupted therapy due to adverse events or IPF progression. The median survival was 1606 days. There was a significant reduction in disease progression rate, as measured by trend of forced vital capacity, after 1 year of therapy with respect to before treatment (p = 0.0085). Forced vital capacity reduction rate was progressively higher in the subsequent years of treatment. Treatment-related side effects were reported in 25 patients and were predominantly mild. Overall, four patients discontinued therapy due to severe photosensitivity. Conclusions: Our findings confirm the efficacy of pirfenidone in reducing functional progression of IPF and its excellent safety profile in a real-life setting. This study, designed on a long-term follow up, contributes to the growing evidence on safety, tolerability and efficacy of pirfenidone in IPF. The reviews of this paper are available via the supplemental material section.

Abstract
We present data on prognostic factors in a Tunisian cohort of people with Idiopathic pulmonary fibrosis. INTRODUCTION Idiopathic pulmonary fibrosis (IPF) has a poor prognosis, with a median survival in patients with the condition of only 3 to 5 years. Previous studies have identified a number of prognostic factors in this chronic pulmonary disease. METHODS We conducted a retrospective study, including patients with idiopathic pulmonary fibrosis (IPF) who were diagnosed at the Pneumology Department of the University Hospital Fattouma-Bourguiba, Monastir, between 1991 and 2014. The aim of this study was to compare clinical, radiological, pulmonary functional predictors of survival in IPF in a Tunisian cohort with those of previous studies. RESULTS This study included 126 patients. Their mean age was 66 years, with a male predominance (68.3%). Respiratory function tests revealed a restrictive ventilatory deficit in 72.6% of cases. The median survival of our study population was 22.5 months [6.7-49.5]. In univariate analysis, factors associated with a poor prognosis were: lower baseline values of TLC, FCV and DLco, level of dyspnea assessed by mMRC scale, hypoxemia at diagnosis, the degree of desaturation during exercise, a higher annual decline of FVC and DLco, acute respiratory distress and also the GAP score. In multivariate analysis, independent prognostic factors were: baseline DLco, level of dyspnea, desaturation at exertion and the annual decline of the DLco. CONCLUSION Lower baseline DLco, the level of dyspnea, desaturation on exercise, and annual decline in DLco are all associated with a poor prognosis in IPF.

Abstract
BACKGROUND Canine idiopathic pulmonary fibrosis (CIPF) is a chronic, interstitial lung disease that mainly affects West Highland white terriers (WHWTs) and is characterized by excessive deposition of extracellular matrix (ECM) in the lung. Matrix metalloproteinases (MMPs) participate in remodeling of ECM. OBJECTIVES To compare metalloproteinase-2, -7 and -9 activities in blood or bronchoalveolar lavage fluid (BALF) samples or both of CIPF WHWTs with healthy WHWTs, healthy dogs of other breeds, and dogs with other lung diseases and determine if these MMPs could be used as diagnostic and prognostic markers for CIPF. ANIMALS Forty-four CIPF WHWTs, 24 dogs with chronic bronchitis (CB), 17 with eosinophilic bronchopneumopathy (EBP), 10 with bacterial pneumonia, 39 healthy WHWTs, and 35 healthy dogs of other breeds. METHODS Cross-sectional observational study. Pro-MMP and active MMP activities were analyzed by zymography. RESULTS In serum, significantly higher (P < .01) pro-MMP-7 activities were observed in CIPF WHWTs compared to healthy dogs of other breeds, dogs with CB and dogs with EBP. In BALF of CIPF WHWTs, both pro-MMP-9 and pro-MMP-2 activities were significantly higher (P < .01) compared to healthy WHWTs, but these differences were not detected in plasma. The CIPF WHWTs had significantly higher (P < .05) activities of pro-MMP-9 compared to dogs with CB and of pro-MMP-2 compared to dogs with CB and EBP. No statistically significant prognostic factors were observed in CIPF WHWTs. CONCLUSIONS AND CLINICAL RELEVANCE Serum MMP-7 and BALF MMP-2 and -9 potentially may be useful diagnostic markers but not prognostic markers for CIPF.

Abstract
Background: Idiopathic pulmonary fibrosis (IPF) is a progressive and fatal interstitial lung disease (ILD). Currently, two antifibrotic drugs are available for reducing forced vital capacity (FVC) decline in IPF. However, many pulmonologists wait before initiating treatment, especially when IPF patients have stable disease. This study aimed to investigate the impact on survival outcome of FVC decline and a slow rate of FVC decline prior to and following treatment with these two antifibrotic drugs. Methods: Out of the 235 IPF patients treated with antifibrotic therapy that were screened, 105 cases were eligible, who then underwent physiological evaluation at 6 months prior to and following antifibrotic therapy. Clinical characteristics and prognostic outcomes were compared among groups, and prognostic factors were evaluated using a Cox proportional hazards analysis. Results: In terms of %FVC decline prior to the therapy and a slow rate of FVC decline, there was no significant difference between stable and worsened groups and responder and non-responder groups, respectively. On the other hand, in terms of %FVC decline (decline >5%) following antifibrotic therapy, the stable/improved group had significantly better prognosis than the worsened group. Prognostic analysis revealed that a stable/improved status following antifibrotic therapy [HR: 0.35 (0.15–0.87)] was significantly associated with a better prognosis. Conclusions: Concerning the FVC decline prior to and following antifibrotic therapy and a slow rate of FVC decline, only the FVC decline following the therapy is associated with a greater survival outcome. An early treatment decision may thus be beneficial for IPF. The reviews of this paper are available via the supplemental material section.

Abstract
BACKGROUND The aim of this study was to compare the clinical characteristics, causes of death and factors impacting on the prognosis of patients with idiopathic pulmonary fibrosis (IPF) and other fibrosing interstitial lung disease (FILD) with a history of acute exacerbation (AE) of IPF or FILD. METHODS Retrospective data of hospital treatment periods caused by AE-IPF and AE-FILD were collected from medical records. Clinical features and survival data of IPF and non-IPF cases were evaluated and compared. The underlying and immediate causes of death were gathered from death certificates. RESULTS A total of 128 patients fulfilled the criteria for inclusion. IPF (n=79/62%), rheumatoid arthritis-associated interstitial lung disease (RA-ILD; n=17/14%) and asbestosis (n=11/8.6%) were the most common FILD subgroups in the study. The median survival after hospitalisation in AE-IPF was 2.6 months compared with 21 months in other AE-FILDs (p<0.001). The survival difference was not explained by age, gender or pulmonary function test results at the time of hospitalisation. Patients with non-specific interstitial pneumonia and RA-ILD had the most favourable prognosis. ILD was the most common underlying cause of death in both patients with IPF and with other FILD accounting for 87% and 78% of deaths, respectively. CONCLUSIONS We detected a significantly longer survival in AE of patients with non-IPF compared with that of AE-IPFs. The prognosis of patients was affected by the underlying lung disease since pulmonary fibrosis was the underlying cause of death in the majority of all patients with FILD having experienced an AE.
