Project description:Interstitial lung diseases (ILD) on the whole have variable prognoses, but there are those which manifest with fibrosis and are characterized by disease progression. Chief among these is idiopathic pulmonary fibrosis, but other ILDs, including autoimmune ILD and chronic hypersensitivity pneumonitis, may have a progressive fibrotic phenotype also. A usual interstitial pneumonia pattern of lung involvement is a prominent risk factor for such a course, suggesting shared fibrotic pathways that may be targeted by antifibrotic therapies. This brief review describes ILDs that are most commonly fibrotic, shared risk factors for development of PF-ILD, and evidence for antifibrotic use in their management.

Project description:BACKGROUND:Those affected by advanced fibrotic interstitial lung diseases have limited treatment options and in the terminal stages, the focus of care is on symptom management. However, quantitatively, little is known about symptom prevalence. We aimed to determine the prevalence of symptoms in Progressive Idiopathic Fibrotic Interstitial Lung Disease (PIF-ILD). METHODS:Searches on eight electronic databases including MEDLINE for clinical studies between 1966 and 2015 where the target population was adults with PIF-ILD and for whom the prevalence of symptoms had been calculated. RESULTS:A total of 4086 titles were screened for eligibility criteria; 23 studies were included for analysis. The highest prevalence was that for breathlessness (54-98%) and cough (59-100%) followed by heartburn (25-65%) and depression (10-49%). The heterogeneity of studies limited their comparability, but many of the symptoms present in patients with other end-stage disease were also seen in PIF-ILD. CONCLUSIONS:This is the first quantitative review of symptoms in people with Progressive Idiopathic Fibrotic Interstitial Lung Diseases. Symptoms are common, often multiple and have a comparable prevalence to those experienced in other advanced diseases. Quantification of these data provides valuable information to inform the allocation of resources.

Project description:Question addressed by the studyMethotrexate (MTX) is a key anchor drug for rheumatoid arthritis (RA) management. Fibrotic interstitial lung disease (ILD) is a common complication of RA. Whether MTX exposure increases the risk of ILD in patients with RA is disputed. We aimed to evaluate the association of prior MTX use with development of RA-ILD.MethodsThrough a case-control study design with discovery and international replication samples, we examined the association of MTX exposure with ILD in 410 patients with chronic fibrotic ILD associated with RA (RA-ILD) and 673 patients with RA without ILD. Estimates were pooled over the different samples using meta-analysis techniques.ResultsAnalysis of the discovery sample revealed an inverse relationship between MTX exposure and RA-ILD (adjusted OR 0.46, 95% CI 0.24-0.90; p=0.022), which was confirmed in the replication samples (pooled adjusted OR 0.39, 95% CI 0.19-0.79; p=0.009). The combined estimate using both the derivation and validation samples revealed an adjusted OR of 0.43 (95% CI 0.26-0.69; p=0.0006). MTX ever-users were less frequent among patients with RA-ILD compared to those without ILD, irrespective of chest high-resolution computed tomography pattern. In patients with RA-ILD, ILD detection was significantly delayed in MTX ever-users compared to never-users (11.4±10.4 years and 4.0±7.4 years, respectively; p<0.001).Answer to the questionOur results suggest that MTX use is not associated with an increased risk of RA-ILD in patients with RA, and that ILD was detected later in MTX-treated patients.

Project description:Fibrotic interstitial lung diseases (ILDs) have a high mortality rate with an unpredictable disease course and clinical features that frequently overlap. Recent data indicate important roles for genomics in the mechanisms underlying susceptibility and progression of pulmonary fibrosis. The impact of these genomic markers on pharmacotherapy and their contribution to outcomes is increasingly recognized. Interstitial lung abnormalities, frequently considered representative of early ILD, have been consistently associated with the MUC5B promoter polymorphism, a common gene variant. Other rare gene variant mutations, including TERT, TERC, SFTPC, and DKC1, may be present in patients with familial interstitial pneumonia and are frequently associated with a usual interstitial pneumonia pattern of fibrosis. The minor allele of the MUC5B rs35705950 genotype is prevalent in several sporadic forms of ILD, including idiopathic pulmonary fibrosis and chronic hypersensitivity pneumonitis. Gene mutations that characterize familial pulmonary fibrosis may be present in patients with connective tissue disease-related ILD, such as rheumatoid arthritis-ILD. Additionally, shorter telomere lengths and mutations in telomere biology-related genes have been demonstrated in both familial and sporadic ILD, with significant implications for disease progression, lung function, and survival. An improved understanding of the impact of genetic and genomic risk factors on disease progression would better guide personalized therapeutic choices in persons with fibrotic ILD.

Project description:BackgroundDehydroepiandrosterone (DHEA) is a precursor sex hormone with antifibrotic properties. The aims of this study were to investigate antifibrotic mechanisms of DHEA, and to determine the relationship between DHEA-sulfate (DHEAS) plasma levels, disease severity and survival in patients with fibrotic interstitial lung diseases (ILDs).MethodsHuman precision cut lung slices (PCLS) and normal human lung fibroblasts were treated with DHEA and/or transforming growth factor (TGF)-β1 before analysis of pro-fibrotic genes and signal proteins. Cell proliferation, cytotoxicity, cell cycle and glucose-6-phosphate dehydrogenase (G6PD) activity were assessed. DHEAS plasma levels were correlated with pulmonary function, the composite physiologic index (CPI), and time to death or lung transplantation in a derivation cohort of 31 men with idiopathic pulmonary fibrosis (IPF) and in an independent validation cohort of 238 men and women with fibrotic ILDs.ResultsDHEA decreased the expression of pro-fibrotic markers in-vitro and ex-vivo. There was no cytotoxic effect for the applied concentrations, but DHEA interfered in proliferation by modulating the cell cycle through reduction of G6PD activity. In men with IPF (derivation cohort) DHEAS plasma levels in the lowest quartile were associated with poor lung function and higher CPI (adjusted OR 1.15 [95% CI 1.03-1.38], p = 0.04), which was confirmed in the fibrotic ILD validation cohort (adjusted OR 1.03 [95% CI 1.00-1.06], p = 0.01). In both cohorts the risk of early mortality was higher in patients with low DHEAS levels, after accounting for potential confounding by age in men with IPF (HR 3.84, 95% CI 1.25-11.7, p = 0.02), and for age, sex, IPF diagnosis and prednisone treatment in men and women with fibrotic ILDs (HR 3.17, 95% CI 1.35-7.44, p = 0.008).ConclusionsDHEA reduces lung fibrosis and cell proliferation by inducing cell cycle arrest and inhibition of G6PD activity. The association between low DHEAS levels and disease severity suggests a potential prognostic and therapeutic role of DHEAS in fibrotic ILD.

Project description:Background:Lung transplantation has long been the accepted therapy for end-stage pulmonary fibrotic disease. Presently, there is an ongoing debate over whether single or bilateral transplantation is the most appropriate treatment for end-stage disease, with a paucity of high-quality evidence comparing the two approaches head-to-head. Methods:This review was performed in accordance with PRISMA recommendations and guidance. Searches were performed on PubMed Central, Scopus and Medline from dates of database inception to September 2019. For the assessed papers, data was extracted from the reviewed text, tables and figures, by two independent authors. Estimated survival was analyzed using the Kaplan-Meier method for studies where time-to-event data was provided. Results:Overall, 4,212 unique records were identified from the literature search. Following initial screening and the addition of reference list findings, 83 full-text articles were assessed for eligibility, of which 17 were included in the final analysis, with a total of 5,601 patients. Kaplan-Meier survival analysis illustrated improved survival in patients receiving bilateral lung transplantation (BLTx) than in those receiving unilateral transplantation for idiopathic pulmonary fibrosis at all time intervals, with aggregated survival for BLTx at 57%, 35.3% and 24% at 5-, 10- and 15-year follow-up, respectively. Survival rates for SLTx were 50%, 27.8% and 13.9%, respectively. Conclusions:Whilst a number of studies present conflicting results with respect to short-term transplantation outcomes, BLTx confers improved long-term survival over SLTx, with large-scale registries supporting findings from single- and multi-center studies. Through an aggregation of published survival data, this meta-analysis identified improved survival in patients receiving BLTx versus SLTx at all time intervals.

Project description:BackgroundEarly identification of fibrotic interstitial lung disease (F-ILD) patients with high risk of progression will help initiate early therapeutic intervention and potential improvement of outcomes. This study was designed to assess the predictors of progression in patients with F-ILD.MethodsPatients with F-ILD in Shanghai Pulmonary Hospital between January 1, 2019 and July 31, 2021 were retrospectively analyzed. The patients enrolled were divided into progressive group and non-progressive group according to the specified criteria. Baseline characteristics were collected and a multivariate regression was conducted to identify independent predictors of progression.ResultsOf the 177 F-ILD cases, 87 were enrolled in the progressive group and 90 were in the non-progressive group. The cohort included 11 types of F-ILD, primarily were connective tissue disease-associated interstitial lung disease (CTD-ILD) (43, 24.3 %), idiopathic pulmonary fibrosis (IPF) (39, 22.0 %), interstitial pneumonia with autoimmune features (IPAF) (32, 18.1 %), and unclassifiable (23, 13.0 %). The highest proportion of progression was seen in nonspecific interstitial pneumonia (NSIP) subgroup (66.7 %), followed by IPF (59.0 %) and HP (57.1 %). After adjusting for gender and age, a course of disease longer than 9.5 months (OR: 2.633; 95 % CI: 1.190-5.826, P = 0.017), lymphocyte in peripheral blood more than 2.24 (109/L) (OR: 2.670; 95 % CI: 1.095-6.510, P = 0.031), and emphysema in high-resolution computed tomography (HRCT) (OR: 2.387; 95 % CI: 1.017-5.640, P = 0.046) were independent predictors of progression in F-ILD patients.ConclusionsThis study suggested that in patients with F-ILD, long course of disease, elevated blood lymphocyte and emphysema on HRCT were independent predictors of progression, which may suggest utility in early therapeutic intervention.

Project description:Rationale: Honeycombing on chest computed tomography (CT) has been described in diverse forms of interstitial lung disease (ILD); however, its prevalence and association with mortality across the spectrum of ILD remains unclear. Objective: To determine the prevalence and prognostic value of CT honeycombing and characterize associated mortality patterns across diverse ILD subtypes in a multicenter cohort. Methods: This was an observational cohort study of adult participants with multidisciplinary or adjudicated ILD diagnosis and documentation of chest CT imaging at index diagnosis across five U.S. hospitals (one tertiary and four nontertiary medical centers). Participants were stratified based on presence or absence of CT honeycombing. Vital status was determined from review of medical records and social security death index. Transplant-free survival was analyzed using univariate and multivariable Cox regression. Results: The sample comprised 1,330 participants (mean age, 66.8 yr; 50% men) with 4,831 person-years of follow-up. The prevalences of CT honeycombing were 42.0%, 41.9%, 37.6%, and 28.6% in chronic hypersensitivity pneumonitis, connective tissue disease-related ILD (CTD-ILD), idiopathic pulmonary fibrosis (IPF), and unclassifiable/other ILDs, respectively. Among those with CT honeycombing, cumulative mortality hazards were similar across ILD subtypes, except for CTD-ILD, which had a lower mortality hazard. Overall, the mean survival time was shorter among those with CT honeycombing (107 mo; 95% confidence interval [CI], 92-122 mo) than those without CT honeycombing (161 mo; 95% CI, 147-174 mo). CT honeycombing was associated with an increased mortality rate (hazard ratio, 1.72; 95% CI, 1.38-2.14) even after adjustment for center, sex, age, forced vital capacity, diffusing capacity, ILD subtype, and use of immunosuppressive therapy (hazard ratio, 1.62; 95% CI, 1.29-2.02). CT honeycombing was associated with an increased mortality rate within non-IPF ILD subgroups (chronic hypersensitivity pneumonitis, CTD-ILD, and unclassifiable/other ILD). In IPF, however, mortality rates were similar between those with and without CT honeycombing. Conclusions: CT honeycombing is prevalent in diverse forms of ILD and uniquely identifies a progressive fibrotic ILD phenotype with a high mortality rate similar to IPF. CT honeycombing did not confer additional risk in IPF, which is already known to be a progressive fibrotic ILD phenotype regardless of the presence of CT honeycombing.

Project description:BackgroundLittle is currently known about the perspectives of people with interstitial lung disease and their carers in relation to the timing of palliative care conversations.AimTo establish patients' and carers' views on palliative care in interstitial lung disease and identify an optimum time to introduce the concept of palliative care.DesignMeta-ethnography of qualitative evidence. The review protocol was prospectively registered with PROSPERO (CRD42021243179).Data sourcesFive electronic healthcare databases were searched (Medline, Embase, CINAHL, Scopus and Web of Science) from 1st January 1996 to 31st March 2022. Studies were included that used qualitative methodology and included patients' or carers' perspectives on living with end-stage disease or palliative care. Quality was assessed using the Critical Appraisal Skills Programme checklist.ResultsAbout 1779 articles were identified by initial searches. Twelve met the inclusion criteria, providing evidence from 266 individuals across five countries. Three stages were identified in the illness journey of a person with interstitial lung disease: (1) Information seeking, (2) Grief and adjustment, (3) Fear of the future. Palliative care involvement was believed to be most appropriate in the latter two stages and should be prompted by changes in patients' health such as respiratory infections, onset of new symptoms, hospital admission, decline in physical function and initiation of oxygen.ConclusionsPatients and carers prefer referral to palliative care services to be prompted by changes in health status. Future research should focus on supporting timely recognition of changes in patients' health status and how to respond in a community setting.
