Interstitial Lung Disease: Causes, symptoms, diagnosis and treatment (1) - Interstitial lung disease (ILD) is a group of lung disorders that affect the interstitium of the lungs. Rapidly progressive (RP) interstitial lung disease (ILD) is frequently associated with anti-melanoma differentiation-associated gene 5 (MDA5) antibody-positive (Ab+) DM and amyopathic DM (ADM) [1]. [90] reported on six cases from a tertiary German centre. In this analysis, phenotypes could be explained, at least partially, by sex, geographical origin and professional environmental exposure. QoL and functionality were the highest priority for outcomes of sarcoidosis patients. Conflict of interest: P. Spagnolo reports personal fees and nonfinancial support from Roche, Boehringer Ingelheim and Zambon, personal fees from PPM Services, Galapagos and Santhera Pharmaceuticals, outside the submitted work. Five cases were idiopathic, eight were associated with hypersensitivity pneumonitis and two with IPF [77]. Conflict of interest: E. Bargagli has nothing to disclose. The 2018 ERS International Congress included several educational and scientific sessions on rare lung diseases, where clinicians and scientists from all around the world shared and discussed new data on the pathogenesis, diagnosis and treatment of these neglected disorders. We encourage readers to follow-up on their personal topics of interest and aim to spark further interest for participation in the 2019 ERS International Congress in Madrid (https://erscongress.org). The median survival time for nonsurvivors was 16.5 years post-diagnosis, and major causes of death were malignancy (26.5%), infection (20.6%) and respiratory failure (11.8%). Interstitial lung disease (ILD) is an umbrella term used for a large group of diseases that cause scarring (fibrosis) of the lungs. Interstitial lung disease (ILD) is the most common pulmonary complication in patients with rheumatoid arthritis (RA). bronchiolitis–interstitial lung disease is increasingly diag-nosed without surgical lung biopsy in smokers on the basis of clinical and imaging features (ground-glass opacities and centrilobular nodules) and bronchoalveolar lavage (smok-er’s macrophages and absence of lymphocytosis). Pulmonary alveolar proteinosis is characterised by alveolar accumulation of surfactant lipids and proteins. In terms of treatment effects, a retrospective analysis of patients with RA-ILD treated (n=26) or not (n=18) with rituximab for joint involvement reported a trend bordering on statistical significance towards a slower rate of lung function decline in the rituximab-treated group [40]. Marangu et al. If you continue browsing the site, you agree to the use of cookies on this website. Respiratory & Constitutional symptoms (20-30%) A detailed genotyping analysis of the mitogen-activated protein kinase (MAPK) pathway in 50 PLCH patients found genetic alterations in 44 (88%). Most of these conditions are orphan, as they are ultrarare, not widely researched and no effective treatment strategies or approved drugs exist [75]. polymorphisms) were associated with specific clinical features, such as TNFA rs1800629 with acute sarcoidosis, but links between genetics and phenotype often varied according to the regional origin of patients. A 24-month survival of 83% was found. [92] studied the predictive factors for relapse in 56 consecutive patients with chronic eosinophilic pneumonia. Wijsenbeek reports grants and other support from Boehringer Ingelheim and Hoffman la Roche, and other support from Galapagos, outside the submitted work. Progressors had higher mortality (p=0.004), but the only predictor of disease progression was lower baseline FVC (mean±sd 70±20% versus 84±27%; p=0.049). Certain drugs used to treat RA, such as methotrexate or anti‐tumor necrosis factor‐alpha antibodies, have been associated with the development or progression of ILD. Nasser et al. Two groups were identified: one with known extracardiac sarcoidosis (n=461) and one with cardiac manifestation as first presentation (n=183). [55] presented results from the GenPhenResa study. Alfaro reports receiving travel support from Boehringer Ingelheim, Novartis, Astra, Menarini, Mundipharma, Zambon and Roche, and grants from Bayer, outside the submitted work. Cough is a common symptom associated with ILD … Finally, the inclusion of a specialist pharmacist in the ILD multidisciplinary team is likely to improve the management of drug interactions and adverse effects, optimising treatment adherence and reducing medical costs [49]. Interstitial lung disease (ILD) is a category of chronic lung conditions that affect the interstitium. In a cohort of 4131 patients with SSc, Kreuter et al. Intensive combination immunosuppressive therapy with high-dose glucocorticoid (GC), CYC and calcineurin inhibitors, such as CSA, has been used to treat anti-MDA5 Ab+ RP-ILD [2], but the prognosis of these patients remains poor despite intensive therapy [2, 3]. Low-dose dexamethasone resulted in a reduction of the inflammatory profile, and improved QoL parameters and fatigue, but with higher weight gain than control patients [59]. The Royal Brompton Hospital [64] reported its large experience of 644 patients referred for suspected cardiac sarcoidosis. The EpiSarc study, Phenotypes of organ involvement in sarcoidosis, Genetic profiles of clinical features in sarcoidosis, Pulmonary function trends predict mortality in patients with hypersensitivity pneumonitis, Mixed ventilatory defects in pulmonary sarcoidosis: prevalence and prognosis. The prognostic value of pulmonary function tests in patients with hypersensitivity pneumonitis has been explored in two large retrospective studies from the Royal Brompton Hospital (London, UK), with decline in FVC ≥10% and in DLCO ≥15% within the first year both being predictive of mortality after adjusting for age, sex, smoking and exposure history [56]. Thank you for your interest in spreading the word on European Respiratory Society . Interstitial lung disease (ILD) is a group of many lung conditions.All interstitial lung diseases affect the interstitium, a part of your lungs. Mortality was higher in patients with mixed and restrictive pattern than those with obstruction alone, but this difference was more linked to the level of DLCO than to the type of ventilatory defect per se. Conflict of interest: C.C. Magnetic resonance imaging (MRI) findings in animal models of drug-induced ILD were correlated with extent of inflammation and fibrosis [50, 51]. There was an association between peripheral lymphopenia and worse lung function. There was improvement in lung function in five patients and stabilisation in seven patients. Chest. Two studies concerning microbiota did not identify a specific profile or pathogen in the lungs of sarcoidosis patients [69, 70]. None of the patients progressed. Conflict of interest: M.S. As a part of this white paper, diagnostic HRCT criteria for usual interstitial pneumonia (UIP) pattern were updated.. Plathythorax, with deepened suprasternal notch on CT, correlated with progression (p<0.01) and death (p<0.05) [78]. In pulmonary sarcoidosis, Kouranos et al. Interstitial (in-tur-STISH-ul) lung disease describes a large group of disorders, most of which cause progressive scarring of lung tissue. An international survey including 1842 patients was undertaken in order to gather views about which treatment outcomes matter most to sarcoidosis patients [58]. Acute onset and rapidly progressive ILD was frequent in this subgroup of patients [44]. interstitial lung diseases 1. However, within the IPAF group, the presence of antisynthetase antibodies was associated with a more frequent acute onset [43]. Children were between 2.1 and 10.8 months of age, and all displayed cough and alveolar infiltrates on chest radiography. See our Privacy Policy and User Agreement for details. Sarcoidosis treatment and outcomes: what is most important to patients? Many factors go into interstitial lung disease life expectancy. Dr. Sally Suliman presents "Interstitial Lung Disease" by first introducing the classification of ILDs. Interstitial lung disease comes in more than 200 different types. See our User Agreement and Privacy Policy. Worldwide, several registers have been established.

Interstitial lung disease (ILD) comprises a wide range of acute and chronic pulmonary disorders that affect both the airways and lung parenchyma with variable amounts of inflammation and fibrosis. Pleuroparenchymal fibroelastosis (PPFE) is a distinctive ILD that may be primary or secondary. Terraneo et al. Patients with ILD can experience acute exacerbations (AE) which are associated with extremely high morbidity and mortality. Progressive fibrosis is associated with worsening respiratory symptoms, lung function decline, limited response to immunomodulatory therapies, decreased … This article is open access and distributed under the terms of the Creative Commons Attribution Non-Commercial Licence 4.0.

Three were treated with sirolimus with good response. | PowerPoint PPT presentation | free to view Cardiac sarcoidosis diagnosis was based on Heart Rhythm Society consensus statement criteria [65] via multidisciplinary team discussion. In addition to the classical rare DPLDs, there were several reports on ultrarare diseases affecting adults and children. Cytometry analysis identified different populations of monocytes and dendritic cells among these compartments, but in different proportions. Schupp et al. In a double-blind, randomised, placebo-controlled trial, the effect of low-dose oral dexamethasone (1 mg) on QoL was studied [59]. Enter multiple addresses on separate lines or separate them with commas. The American Thoracic Society improves global health by advancing research, patient care, and public health in pulmonary disease, critical illness, and sleep disorders. Reviews the role of surgical lung biopsy in the diagnosis and treatment of interstitial lung disease with specific focus on when a biopsy can be diagnostic as well as when it should be avoided. Regarding phenotyping sarcoidosis, Lhote et al. [38] confirmed that ILD is the most frequent type of pulmonary complication, followed by pulmonary hypertension (PH)-ILD and PH alone, with PH-ILD having the worse survival. Although these conditions are rare, a proportion of patients with interstitial lung diseases (ILDs) may develop a progressive-fibrosing phenotype. We do not capture any email address. [91] reported on a US national registry for childhood ILDs. Blood tests and pulmonary function testing were not viewed as important. In this large European cohort including more than 2100 Caucasian sarcoidosis patients, genetic profiles associated to specific phenotypes were studied. Finally, in a Japanese study comparing histological findings between anti-neutrophil cytoplasmic antibody myeloperoxidase-positive (MPO+) ILD patients (n=28; 20 with a histology pattern of UIP) and IPF, a greater degree of peri-bronchiolar inflammation was seen surrounding cystic lesions in MPO+ ILD, suggesting that the pathogenesis of the cystic changes seen in a UIP pattern associated with MPO+ may differ from the honeycomb lesions of IPF [45]. Pulmonary lymphangiomatosis is an extremely rare disease characterised by lung, pleural and mediastinal infiltration by abnormal lymphatics. Schott et al. Löfgren syndrome patients had a decreased frequency of dendritic cells in bronchial tissue and lymph nodes, which may translate to differences in T-cell responses associated with disease progression. Purchase Interstitial Lung Disease - 1st Edition. Decreased expression of lymphocyte activity genes was observed and associated with a more severe phenotype in sarcoidosis, but also in other ILDs. Raj R, Raparia K, Lynch DA, et al. Some genetic variants (e.g. Evaluation and management of QoL impairment are essential in sarcoidosis. Cardiac sarcoidosis was the subject of three presentations. Conflict of interest: K. Antoniou has nothing to disclose. In a study of 62 lung transplanted patients, 15 had PPFE in pre-transplant imaging studies. [88], from Cape Town, South Africa, reported on 12 Zimbabwean children with exogenous lipoid pneumonia caused by repeated oil administration for cultural reasons. The most frequent disease was diffuse idiopathic pulmonary neuroendocrine cell hyperplasia. Radzikowska et al. diminished peripheral responses) on peripheral blood mononuclear cells from sarcoidosis patients with a gene network analysis. Interstitial lung disease refers to inflammation in the interstitial tissue of the lungs, the spaces that surround and separate the air sacs. Many people living with interstitial lung disease often wonder about their interstitial lung disease life expectancy. 2017; 151:1131-40. A case-control study. Non specific interstitial pneumonia and features of connective tissue disease: what are the consequences of a different point of view? Additionally, all the three reported deaths occurred in the Down syndrome group. Young et al. Here is the information you need to live the best life possible. Depending upon definition criteria, 25–35% of sarcoidosis patients with airflow obstruction had a mixed pattern, which was associated with further DLCO reduction compared with patients with only airflow obstruction, and higher prevalence of chest radiographic stage IV than other ventilatory defects (63.5% for mixed versus 38.3% for obstructive versus 38.5% for restrictive defects). Therefore, a new therapy is required for RP … Clipping is a handy way to collect important slides you want to go back to later. Interstitium refers to those tissues that surround the alveoli or tiny air sacs of the lungs. Conflict of interest: T.M. Innovative gadgets in anesthesia and medicine, Neuropathic pain understanding and management, No public clipboards found for this slide. The use of in vivo confocal laser endomicroscopy during bronchoscopy in nine patients with ground-glass changes on CT provided additional information and appeared to allow differentiation between inflammatory versus fibrotic changes as the underlying cause of ground-glass opacities (partially filled alveoli by cellular infiltrates versus fine fibrosis) [52]. In a large cohort of 82 anti-MDA5-positive patients, the prevalence of ILD was high (63%), with NSIP being the most frequent pattern. Although these conditions are rare, a proportion of patients with interstitial lung diseases (ILDs) may develop a progressive-fibrosing phenotype. An alternative hypothesis is the existence of a phenotype associating obstruction and cardiac sarcoidosis. Preliminary data on the effect of nintedanib on fibroblasts from patients with SSc-ILD and control lungs suggest that nintedanib inhibits myofibroblast differentiation and contractility [41]. Aug. 31, 2018─A new international guideline has been developed to help physicians diagnose idiopathic pulmonary fibrosis (IPF), a rare and often fatal lung disease whose cause is unknown. Some of these gene alterations lead to variable sensitivity to MAPK targeting drugs and the authors proposed this strategy for refractory cases [84]. Mononuclear phagocytes in the bronchial tissue and BAL were more activated than in blood and lung lymph nodes, indicating local inflammation. In a large review of the Swedish respiratory failure registry, comprising 1603 ILD patients, the use of low-dose benzodiazepines and the use of either low or high doses of opioids for symptom management of patients with oxygen-dependent ILD appeared safe, since no increased hospital admissions or mortality were reported, whereas an association between high-dose benzodiazepines and mortality was observed [48]. In particular, patients with non-IPF progressive fibrosing ILD had higher healthcare utilisation and costs compared with other ILD patients, underlining the need to focus resources in this group [47].
