B. Bronchiectasis. In these times of fear of an unknown, lethal disease that could possibly affect entire populations, the discovery, in 1983, of HIV, the virus that causes AIDS, was of critical importance. The study also explored the relationship between trough serum AAT levels and the rate of lung density decline. Pulmonary alveolar proteinosis, a rare lung disease, is caused by a build-up of material in the air sacs. However, as a specialist, it is necessary to identify and confirm such a diagnosis in a patient. Lung Diseases List. Pulmonary alveolar proteinosis (PAP) is a rare lung disease in which surfactant-rich lipoproteinaceous material accumulates within the alveolar space (154). Collaboration between the sponsor, academia, and regulatory agencies is the prime determinant of a trial׳s success. The diagnostic gold standard for the quantitative assessment of emphysema is histopathology, but tissue sampling requires invasive methods. An excellent, detailed overview of the history of the HIV epidemic has been collated by Avert, an international HIV and AIDS charity (see websites listed below). “Spirometric gating” employs a device to measure lung volume during image acquisition in order to either control inspiratory level at the time of imaging [51], or to retrospectively select imaging data acquired at designated phases of the respiratory cycle [52]. However, the practical difficulties of performing a randomized, placebo-controlled trial in a rare lung disease, such as AATD, using FEV1 as the outcome measure have been shown to be prohibitive [40]. There are many types of lungs diseases which need to be taken care of in time as they may lead to fatal conditions. Although evidence-based guidelines for the diagnosis and treatment of IPF have been issued [8], many aspects of the disease remain ill defined. It happens most often in people in the age range of 30 to 60 years. Seeing an average of 200 patients a year, we are experts in managing conditions such as interstitial lung disease (ILD), surfactant mutations, lung development disorders and lymphatic disorders. By continuing you agree to the use of cookies. Consequently, the practical alternative for use in routine clinical practice is that of physiological testing and the same approach has historically been adopted for the assessment of outcome in interventional studies of emphysema modifying therapy. A response-exposure curve with the shaded area representative of 90% confidence limits. The approach that was adopted is entirely logical because CT images are densitometric maps and emphysema leads to the loss of lung density because it is characterized by proteolytic destruction of lung tissue and by hyperinflation secondary to an increase in compliance. This complicates the performance and interpretation of imaging-based morphometry. Wegener’s granulomatosis is a rare disorder in which the blood vessels become inflamed, restricting blood flow to various organs 2 4.Wegener’s granulomatosis most commonly affects the lungs and upper respiratory tract 2 4.The first sign of Wegener’s granulomatosis occurs in the respiratory tract, causing shortness of breath 2 4. This issue is not just of methodological concern, since the conventional understanding that emphysematous damage reduces lung mass has been questioned. You will find below the list of the rare lung diseases recorded in SIOLD registries: Swiss group for Interstitial and Orphan Lung Diseases, Articles for public on rare lung diseases, Patient associations for rare lung diseases, desquamative interstitial pneumonia (DIP), respiratory bronchiolitis interstitial lung disease (RBILD), nonspecific interstitial pneumonia (NSIP), cryptogenic organizing pneumonia (COP = idiopathic BOOP), idiopathic interstitial pneumonia : unspecified, chronic idiopathic eosinophilic pneumonia, idiopathic hypereosinophilic syndrome with pulmonary manifestations, hypereosinophilic lung disease: other (specify), alveolar hemorrhage syndrome of undetermined origin, alveolar hemorrhage syndrome of determined origin, Sporadic pulmonary lymphangioleiomyomatosis (S-LAM), Pulmonary lymphangioleiomyomatosis in tuberous sclerosis (TSC-LAM), pulmonary manifestations in inflammatory bowel diseases, severe hepatopulmonary syndrome (pa02 < 55 mmHg), interstitial lung disease in systemic sclerosis, interstitial lung disease in rheumatoid arthritis, interstitial lung disease in idiopathic inflammatory myopathies (polymyositis, dermatomyositis, anti-synthetase syndrome), interstitial lung disease in Sjögren syndrome, interstitial lung disease in mixed connective tissue disease (MCTD), interstitial lung disease in overlap syndromes, interstitial lung disease in undifferentiated connective tissue disease, combined pulmonary fibrosis and emphysema without associated connective tissue disease, combined pulmonary fibrosis and emphysema with connective tissue disease. To achieve high precision and uniformity of lung function measurements, the same spirometric equipment was used across all participating centers. If lung disease is taking your breath, you do not have to deal with it alone. This led to CT lung density measurements being used as an objective, noninvasive, direct assessment of emphysema in vivo. Patients with idiopathic PAP typically have clinical symptoms of progressive dyspnea and cough with a chest radiograph that suggests an alveolar filling process. Almost 50% of patients were on PAH-specific therapy, suggesting that baseline hemodynamics and functional parameters may be more severe in treatment-naive patients; this is also suggested by the more profound alteration of these parameters in the study by Fartoukh and colleagues17 (CI, 2.6 L/min/m2; PVR index, 25 WU/m2). Computed tomography reveals a pattern of ground glass opacification with intralobular and interlobular septal thickening. 10.8) and there was an absence of a demonstrable plateau within the observed dose range. A significant obstacle to the performance of accurate and precise morphometry is the distensibility of the lung, which consists mostly of air when fully inflated. 1). Substantial prevention success has in particular been achieved in Sub-Saharan Africa. Pulmonary transplantation remains a viable option for these patients. The bronchoscopic appearance alone is usually diagnostic, and biopsy is seldom if ever required.31 In the rare bronchoscopic biopsy showing the cartilaginous or ossified lesions of tracheobronchopathia osteochondroplastica (Fig. The platform is primarily aimed at patients and care Alternative methods have utilized mathematical modeling for volume correction [53–56] and, since these methods have been shown to reduce variability to a degree that is acceptable for longitudinal studies, they are recommended for densitometric studies of emphysema [48]. The 15th percentile point (Perc15) is defined as the cut-off value in HU below which 15% of all voxels are distributed and, as a true measure of density, this index consequently decreases with worsening emphysema. LIP is frequently associated with connective tissue diseases or infections. This causes shortness of breath. Immunodeficiency in AT is variable, with both humoral and cellular abnormalities. This chapter reviews two rare lung diseases in women, benign metastasizing leiomyoma (BML) and lymphangioleiomyomatosis (LAM), which are non-neoplastic diseases that behave in many ways like neoplastic disease. ERN-LUNG ONLINE EXPERT ADVICE SYSTEM The EXpert Advisory BOard (EXABO) is a pan-European internet platform, which has been developed in the context of ERN-LUNG in liaison with the Medical Informatics Group of University Hospital Frankfurt, to answer questions on all aspects of rare respiratory diseases. General Information about Rare Lung Disease General Information about Rare Lung Disease Hermansky-Pudlak syndrome (HPS) is a rare multisystemic hereditary disease manifested by oculocutaneous albinism (OCA), visual impairment, and bleeding diathesis. However, a number of different approaches have been adopted to control inspiratory movements or apply a correction factor to reduce lung volume variability and increase the precision of densitometry. Respiratory manifestations include recurrent infections related to immunodeficiency, chronic aspiration due to swallowing dysfunction, ineffective airway clearance, and interstitial lung disease. And because there is no cure, a diagnosis of pulmonary fibrosis can bring up a lot of emotions for both patients and caregivers. Interstitial lung diseases (ILD) are a group of rare lung conditions that cause chronic breathlessness. Copyright © 2021 Elsevier B.V. or its licensors or contributors. Most patients die young of respiratory causes or malignancies, with a disparately higher mortality rate among African Americans historically.28 As is true for most rare lung diseases, there are few controlled trials to guide management. It is also clear that other prevention programs have been strengthened, including the availability of free, anonymous, and voluntary counseling and testing for HIV (VCT), as well as the promotion and distribution of condoms. Also, while HIV infections still occur at high rates, with an estimated 2.6 million new infections diagnosed in 2009, this number is down by 21% compared to 1997, when the annual number of new infections is thought to have peaked. Since Steiner first described the disease in 1939, there have been approximately 100 reported cases of BML. J.B.F. Rare lung diseases encompass a broad spectrum of conditions and affect an estimated 1.2-2.5 million people in North America and 1.5-3 million people in Europe. The 5-year mortality remains between 33% and 50% and is likely to vary based on the underlying disease process. Similar results were observed in mice deficient in the βc chain of the GM-CSF receptor (157,158). A lack of standardization also prevents comparison between centers and studies. Reluctance among potential study centers may also be explained by the high standards of ICH Good Clinical Practice (GCP) required by both the sponsor and regulatory authorities (e.g., the FDA, EMA, and PMDA). Mean 6MWD was 355 m. Mean PVR was 6.9 Wood units (WU), cardiac index (CI) was maintained at 3.2 L/min/m2, and 38% of patients were using supplemental oxygen. Once the etiological agent was know, diagnostic tests could be developed and epidemiological studies could be conducted to assess prevalence, incidence and risk factors. The problem usually develops over the age of 50 years, and can affect both men and women, and also children. Pulmonary fibrosis is a rare lung disease that causes irreversible scarring of the lungs, which can cause shortness of breath and a persistent cough, and progressively gets worse over time. Voxel distribution histograms in healthy and emphysematous lungs; the effect of lung density loss leads to a left shift in the histogram. While planning the global IPF trials, BI sought expert support through establishing a steering committee (Fig. while in the United States it is a disease that affects fewer than 1 in 200,000, at any given moment. Computed tomography of the chest in patients with LIP may reveal ground-glass opacities, centrilobular and subpleural nodules, and randomly distributed thin-walled cysts. The multiple, non-calcified, benign, smooth muscle pulmonary nodules of BML can mimic a malignancy. While this treatment did not have a significant benefit on the decline in CT lung density, interesting trends were observed in total lung capacity (TLC) and residual volume. Multiple SFTPB mutations have been described (165,168) and deletion of SFTPB in a murine model essentially recapitulated the clinical findings. Infiltration of the walls of small and medium-sized pulmonary arteries with Langerhans cell granuloma has been described in lung regions with prominent parenchymal PLCH nodules, suggesting that a specific pulmonary vasculopathy may contribute to PLCH-PH development.35,116 However, this finding was rare in another study.17 Plexogenic lesions are not typically seen in PLCH-PH, but have been described in 1 case report.117 A more consistent finding is diffuse medial hypertrophy with intimal fibrosis and/or proliferation.17,35,116 These changes are frequently found even in regions not involved with PLCH nodules.17 Furthermore, proliferative involvement of pulmonary veins has been described as well, and aspects of PVOD-like disease were detected in one-third of investigated specimens of patients in the series by Fartoukh and colleagues.17 Even though prominent vascular changes frequently occur in regions not affected by parenchymal PLCH lesions, PH seems to develop predominantly in patients with significant parenchymal disease. Demonstrating polyclonality with immunohistochemistry is the key to differentiating LIP from lymphoma. Figure 10.6. In studies of patients with advanced PLCH referred for lung transplantation, RHC-confirmed PH was present in 92% to 100% of patients.17,112 Hemodynamic alterations were pronounced in both studies, with 73% of patients having an mPAP greater than 35 mm Hg in one study,112 and with mPAP being 59 ± 4 mm Hg in the other.17 In a more recent study of 29 patients from the French PLCH registry, average mPAP was 45 mm Hg, and 19 patients had an mPAP greater than or equal to 40 mm Hg, consistent with severe PH.35 These studies indicate that PH is not only common in PLCH but may also be severe. Only very rarely are ILDs inherited. Antiretroviral drugs provided to HIV-positive pregnant women can substantially reduce the likelihood of their children being infected. Generalized lymphatic anomaly (GLA), also known as lymphangiomatosis, is a rare condition in which the lymphatic vessels proliferate abnormally in some areas of the body. Rare Lung Fungal Disease . Wegener's Granulomatosis. Many, but not all, of these diseases are genetic, meaning they are caused by changes in DNA and can be passed down in families; for these conditions, symptoms of disease usually appear very early in life. Rates of lung density decrease at total lung capacity versus trough therapeutic plasma alpha-1-antitrypsin levels. Studies also found hemodynamic alterations in PLCH to be more pronounced than in the setting of idiopathic pulmonary fibrosis (IPF)17,113 or chronic obstructive pulmonary disease.17 These observations corroborate earlier studies showing that exercise capacity in patients with PLCH generally is limited by pulmonary vascular disease rather than ventilatory limitations.114,115, Survival data in PLCH-PH are sparse, but a recent study from the French registry reported 1-year, 3-year, and 5-year overall survival of 96%, 92%, and 73%, respectively.35 In the same study, WHO functional class was the only variable significantly associated with death from PLCH-PH.35. Diagnosing and caring for children with rare lung diseases is our specialty. Voxel index (VI) below 950 Hounsfield Units (−950 HU) is defined as the proportion of lung voxels of low density below a threshold of −950 HU and this index increases with worsening emphysema. The imaging protocol that was employed utilized percentile density and statistical volume correction [48] to demonstrate a reduction in the annual rate of lung density loss in the actively treated arm (Fig. Rates of lung density decrease at TLC during the double-blind and open-label portions of the trial in (A) all patients and (B) patients completing the open-label study only. One potential explanation for this phenomenon is the induction of diffuse pulmonary vascular remodeling as a consequence of the release of proinflammatory cytokines and growth factors by PLCH granuloma. Using a PH definition of SPAP greater than 35 mm Hg on echocardiogram, one retrospective cohort analysis of 123 unselected patients with PLCH reported a prevalence of 10.6%.111 However, echocardiography was only performed in symptomatic patients (n = 17), thus potentially underestimating the true prevalence of PLCH-PH. A number of densitometric indices derived from the lung voxel histogram have been advocated [43–46] (Figs. Consultant Day & Time Frequency Location Contact Information; Dr. Cormac McCarthy : Tuesday 15:00 - 17:15: Monthly: Suite 5 Ground Floor Herbert Wing: tel: (01) 221 6100 fax: (01) 221 6230: Back to top of page. They can be aggressive and their primary clinical manifestation in the lung may in fact represent a metastatic process. Here is a list of breathing disorders with information on symptoms, causes, treatment and disease management. A modelled response-exposure curve was suggestive of a dose-effect (Fig. Moreover, there are no universally accepted severity grading and prognostic scoring systems for IPF, no uniform definition of IPF exacerbations, and no globally accepted standard of care. This Monograph comprehensively covers the most common and/or complex of these orphan lung diseases. Lung function measurement can be challenging because of neurologic abnormalities but can be useful to define bronchodilator response and to monitor lung function over time. This includes, for example, leading discussions with clinicians involved in the disease management from various countries and asking for their opinion on whether the diagnostic/therapeutic situation is specific to their country or to the disease. A global clinical trial for rare diseases, such as IPF, faces additional, partly unknown challenges. This cancer is rare in individuals under 40 years of age and extremely rare in children and adolescents. Finally, some cases of pediatric PAP have been linked to mutations in the βc chain of the GM-CSF receptor (166). Other conditions associated with endoluminal nodular lesions include endobronchial sarcoidosis, endobronchial granulomatous infections, papillomatosis, and tracheobronchial calcinosis. However, the practical difficulties of performing a randomized, placebo-controlled trial in a, (Permission for publication obtained from the Lancet. While individual rare lung diseases affect less than 1 in 2000 individuals, collectively they have a significant impact upon the population at large. A specific problem of global trials in rare diseases, including IPF, is poor recruitment. William E. Lawson, James E. Loyd, in Emery and Rimoin's Principles and Practice of Medical Genetics, 2013. This is clearly essential for the monitoring of progressive disease and when specific outcomes are needed in interventional studies of therapy for the attenuation or reversal of disease progression. Broncholaveolar lavage yields a milky opaque fluid rich in surfactant, while lung biopsy reveals eosinophilic material in the airspaces, but with relatively preserved alveolar architecture. Interstitial lung disease comes in more than 200 different types. As a result of increasing numbers of people receiving treatment, AIDS-related deaths declined from a peak of 2.1 million in 2004 to an estimated 1.8 million in 2009. 2). There are numerous possible causes of ILD, including connective tissue disorders, autoimmune diseases (e.g. Chronic Lung Allograft Dysfunction (CLAD) Other Rare Lung Diseases (ORLD) Since 2001, the estimated number of people living with HIV (PLHIV) has increased by 16%, which is in part explained by the successful expansion of access to antiretroviral treatment (ART) that is saving lives. The list of diseases included here was drawn from the NIH Center for Advancing Translational Sciences Office of Rare Lung Disease Research,* and from the work of a small group of ATS Members who studied the ATS 2015 Abstracts. We use cookies to help provide and enhance our service and tailor content and ads. BML is an extremely rare disease of unknown etiology that primarily affects women. Orphan diseases are those which are not widely researched, those where specific treatments are not available, and those which may only be of limited interest to scientists and doctors. In its 2010 report on the global epidemic, the Joint United Nations Program on AIDS (UNAIDS) estimated that by the end of 2009 a total of 33.3 million people were living with HIV worldwide, of whom 2.5 million were children younger than 15 years. Asthma. Secondary forms of PAP are caused by impaired function or decreased numbers in the macrophage population, such as can be seen with immunosuppression, some types of hematologic malignancies, some infections, and inhalation of toxic dusts or fumes (154). DLCO was significantly decreased at 27% and 28% of predicted. Values on the graphs are annual rates of decrease. Tanmay S. Panchabhai MD, ... Kristin B. Highland MD, MSCR, in Clinics in Chest Medicine, 2016. Individuals with idiopathic PAP revealed have antibodies against GM-CSF in the serum and bronchoalveolar lavage (159,160), leading to aberrant alveolar macrophage function and accumulation of the surfactant-rich material. [1-3] It can develop in virtually all organs, including the brain, lung, heart, liver, spleen, and bones. Programs that provide sterile needles and syringes are effective harm reduction measures to prevent the spread of HIV and other infectious agents, notably the hepatitis C virus, among people who inject drugs. Medical therapies to date have been ineffective due to the lack of clinical trials. Immunodeficiency does not seem to progress over time in AT.30 Bronchiectasis develops in many patients in the first decade of life. Daniel Lesser MD, ... James S. Hagood MD, in Kendig's Disorders of the Respiratory Tract in Children (Ninth Edition), 2019, Ataxia telangiectasia (AT) is an autosomal recessive, progressive multisystem disorder caused by homozygous or compound heterozygous mutations in the gene ATM (ataxia-telangiectasia mutated; 11q22.3).27 Disease manifestations occur in early childhood, with progressive cerebellar ataxia and later conjunctival telangiectases, progressive neurologic degeneration, immune deficiency, and malignancies. In contrast, therapy-related repair may reverse density loss by reducing compliance and hyperinflation, without necessarily altering tissue mass. ), Essential rules and requirements for global clinical trials in rare lung diseases: A sponsor׳s standpoint, Among the obstacles to the clinical trials in, Tanmay S. Panchabhai MD, ... Kristin B. Highland MD, MSCR, in. NSCLC is the most common form of lung cancer; it is a general term for several different types of cancer in the lungs including adenocarcinoma, squamous cell carcinoma, large cell (undifferentiated) carcinoma, and other rare forms. Murine models provided significant insight into the pathogenesis of PAP, when it was noted that mice deficient in granulocyte–macrophage colony-stimulating factor (GM-CSF) developed pulmonary disease with the same histologic features noted in PAP (155,156). The pathogenesis of PLCH-PH is not well understood. By Mamta Singh. The elimination of differences in inspiration level on sequential imaging may mask important pathophysiological changes: for example, density loss may occur with emphysema progression even in the presence of preserved lung mass, because of worsening hyperinflation. Figure 10.8. A second “exploratory” randomized placebo-controlled study of AATD augmentation therapy (EXACTLE) [50] sought to identify the optimum approach to the use of CT densitometry as the primary outcome measure; a particular aim was to identify the optimum means for overcoming the variability that was known to arise from differences in lung volume between imaging time-points. 1. Semiautomated software facilitates image analysis and reduces the inter- and intraobserver variability (and tedium) that plague visual scoring methods. 8 per million adult women, and a median age at diagnosis of 35 years. Difficult to Diagnose Rare Diffuse Lung Disease presents the theoretical basis and practical aspects of differential diagnoses of rare lung diseases with the use of new method of probe-based confocal laser endomicroscopy (alveoscopy) of the distal respiratory region. 2. Figure 10.5. [1,4] Congenital abnormalities in the developing lymphatic system are thought to play a major role in pathogenesis of the condition, with … Worldwide, 5.2 million people received ART in 2009, a 30% increase compared to only 12 months earlier. SFTPC mutations can not only cause ILD in childhood but have also been associated with pediatric cases of PAP (21). Most TSC-LAM patients have a mutation in a gene that codes for a protein called tuberin, and some have mutations in a gene that codes for the protein hamartin. Evaluations of these models delineated that macrophage function was impaired leading to the accumulation of foamy macrophages in the airspaces that were filled with surfactant-rich material, an observation identical to that seen in PAP. The Rare Lung Diseases Consortium (RLDC) is a network of physicians and patients working to accelerate clinical research and improve medical care for individuals with Rare Lung Diseases. TSC-LAM is a rare genetic disease that causes tumor growth in the brain, kidneys, heart, eyes, lungs, and skin. ), (Permission for publication obtained from The Lancet. As in other diseases, disproportionate decreases in DLCO, poor exercise capacity, and exertional decreases in oxygen saturations may indicate the presence of PH.17,35,114,115, Thomas Kuerner M.D., in Respiratory Investigation, 2015. Idiopathic LIP is rare; every attempt must be made to diagnose underlying conditions when LIP is diagnosed. A minority of patients may experience cough, dyspnea, and hemoptysis. Despite severely altered hemodynamics, a positive vasodilator response may be seen in up to one-third of patients,17 but the clinical significance of this finding is unknown. Muddassir Aliniazee, Marilyn K. Glassberg, in Principles of Gender-Specific Medicine (Second Edition), 2010. The molecular pathogenesis is complex but involves abnormal DNA damage responses leading to a high rate of intrachromosomal recombination and genomic instability. This relationship was interpreted as indicating the possible need for individually tailored dosing regimes, although future studies will be required to establish the validity of this supposition. What is a rare lung disease? Sponsors therefore find it difficult to conduct clinical trials based on the latest scientific developments and guidelines, and in consensus with clinical experts and regulatory agencies, such as the FDA, European Medicines Agency (EMA), and Pharmaceuticals and Medical Devices Agency (Japan) (PMDA). For many years, whole-lung lavage remained the main therapeutic approach (154). 61.4.5 Pulmonary Alveolar Proteinosis. Rare Lung Disease Clinic. in understanding rare lung diseases pathogenesis and disease-modifying therapies,3 rare lung diseases remain an important public health concern because of high morbidity and mortality in the United States and worldwide.4 Outside of lung transplantation, there are no cures for rare lung diseases, and early disease recognition remains limited. LAM lung disease (lymphangioleiomyomatosis) is a rare lung disease that tends to affect women of childbearing age. Tracheobronchopathia osteochondroplastica is a rare lung disease characterized by the presence of cartilaginous or osseous submucosal nodules that bulge into the lumen of the trachea and bronchi (Fig. Clearly, further studies are required to establish whether this is the correct interpretation. A rare disease is one that affects less than one person in every 2,000. Orphan lung diseases differ from the more common pulmonary disorders, due to the fact that the respiratory physician will only see a few of them each year or even during their career. On the basis of CT-measurements, loss of lung density is still to be observed even after the lung volume changes from progressive hyperinflation are eliminated [50,59] and, therefore, lung mass must reduce with emphysema progression. Lymphocytic interstitial pneumonia (LIP) is a rare lung disease on the spectrum of benign pulmonary lymphoproliferative disorders. The optimum method, which was a combination of statistical volume correction and endpoint analysis, achieved statistical significance (P = 0.049). Congenital forms of PAP are caused by mutations in SFTPC, SFTPB, and the βc chain of the GM-CSF receptor (8,21,164–167). Consequently, the practical alternative for use in routine clinical practice is that of physiological testing and the same approach has historically been adopted for the assessment of outcome in interventional studies of emphysema modifying therapy. Rare Lung Disease. Today, we know that there are three main ways in which HIV is transmitted: contact with blood, mother-to-child transmission, and sexual intercourse. … Facilities specialized in the treatment of such diseases are generally attractive candidates for clinical trials. CT densitometry has its origins in Scotland when, in 1984, it was observed that the lung voxel histograms of CT images from patients with emphysema were significantly different from normal [42]. This may sound like a very small number, but as there are 700 million people in Europe, one ‘rare’ disease could affect up to 350,000 Europeans; that’s almost the population of Malta. Transmission via this route is preventable through the use of sterile equipment; disinfecting equipment reduces the likelihood of transmission but does not eliminate it. A. The potential advantages of using CT lung density as a surrogate outcome measure for studies of emphysema-modifying therapy in patients with AATD were quickly appreciated: AATD-related COPD was considered to be a relatively homogeneous emphysematous phenotype and replacement therapy for the arrest or retardation of emphysema progression was already in clinical use.
