rare lung disease

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. However, the practical difficulties of performing a randomized, placebo-controlled trial in a, (Permission for publication obtained from the Lancet. Antiretroviral drugs provided to HIV-positive pregnant women can substantially reduce the likelihood of their children being infected. 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. CT lung densitometry has also been used as an outcome in a proof of concept study of the use of an oral γ-selective retinoid agonist in AATD [58]. Substantial prevention success has in particular been achieved in Sub-Saharan Africa. Respiratory manifestations include recurrent infections related to immunodeficiency, chronic aspiration due to swallowing dysfunction, ineffective airway clearance, and interstitial lung disease. Generally the causes of these diseases are unknown. Voxel distribution histograms in healthy and emphysematous lungs; the effect of lung density loss leads to a left shift in the histogram. 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). As an international company and a sponsor, BI is fully aware of these difficulties, which need to be properly addressed and managed before study implementation as well as during the trial. 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. What is a rare lung disease? Most recently, the results of a suitably powered study (n = 180 over 2 years) have demonstrated that intravenous augmentation therapy with an alpha-1-proteinase inhibitor is effective in retarding the decline in CT-measured lung density. If lung disease is taking your breath, you do not have to deal with it alone. The study, carried out in collaboration with Stanford University School of Medicine, compared lung cells of patients with the disease with those of healthy individuals. The presence of pulmonary venous involvement may predispose patients to pulmonary edema with pulmonary vasodilators,35,122,123 as seen in 2 patients in the series by Fartoukh and colleagues.17, Predictors of PH development in PLCH have not yet been described, as no formal comparisons exist between patients with PLCH with and without PH. 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. For example, to define general standards for the diagnostic procedures used in patients with IPF, BI established image acquisition guidelines for high-resolution computed tomography (HRCT) scans and provided all study centers with appropriate software to transmit the HRCT data for central review. Interstitial lung diseases (ILD) are a group of rare lung conditions that cause chronic breathlessness. Sexual transmission is by far the most important route for the spread of HIV globally. Appointments 216.444.6503 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. There are numerous possible causes of ILD, including connective tissue disorders, autoimmune diseases (e.g. The disease is not benign despite the hypothesis that BML originates from uterine leiomyomas, a common neoplasm that has a prevalence of 3–20%. The molecular pathogenesis is complex but involves abnormal DNA damage responses leading to a high rate of intrachromosomal recombination and genomic instability. Nevertheless, there is a close correlation between CT and pathology for a wide range of densitometric indices [43–46] and it is likely that a rigid limitation to the use of one index over another at the present time is unjustifiable. 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. 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.

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. The multiple, non-calcified, benign, smooth muscle pulmonary nodules of BML can mimic a malignancy. 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. 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.

Kevin O. Leslie MD, in Practical Pulmonary Pathology: A Diagnostic Approach (Second Edition), 2011. It is often difficult to find enough study centers, as few institutions have both expertise in the treatment of the respective disease and a reasonable number of patient referrals. 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. A number of densitometric indices derived from the lung voxel histogram have been advocated [43–46] (Figs. TSC-LAM is a rare genetic disease that causes tumor growth in the brain, kidneys, heart, eyes, lungs, and skin. This led to CT lung density measurements being used as an objective, noninvasive, direct assessment of emphysema in vivo. The study also explored the relationship between trough serum AAT levels and the rate of lung density decline. 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. 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. 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. Pulmonary transplantation remains a viable option for these patients. Bronchitis. [1,4] Congenital abnormalities in the developing lymphatic system are thought to play a major role in pathogenesis of the condition, with … 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).

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. “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]. Furthermore, while the method of volume correction of FRC images to the predicted TLC volume may improve precision, it will not overcome the confounding influence of air-trapping on density measurements. This may translate into difficulties in designing appropriate study protocols and standardizing all relevant elements of the study, including well-defined diagnostic, inclusion, and exclusion criteria, and suitable endpoints. Notwithstanding the surrogate nature and limitations of these physiological measures, they are commonly seen as the accepted standard against which new methods are compared. 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. A global clinical trial for rare diseases, such as IPF, faces additional, partly unknown challenges. In contrast, therapy-related repair may reverse density loss by reducing compliance and hyperinflation, without necessarily altering tissue mass. … Four approaches to data analysis were incorporated in the EXACTLE study through a combination of statistical versus physiological volume correction, and endpoint versus slope analysis. 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. In vivo morphometry of CT images therefore represents a tool that compares with the gold standard of ex vivo histopathological morphometry [41], and the close relationship between structure and function gives clinical relevance to these measurements. 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. 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. 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. By Mamta Singh. 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. The diagnostic gold standard for the quantitative assessment of emphysema is histopathology, but tissue sampling requires invasive methods. Other conditions associated with endoluminal nodular lesions include endobronchial sarcoidosis, endobronchial granulomatous infections, papillomatosis, and tracheobronchial calcinosis. 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. The Rare Lung Disease Program’s mission is to provide state of the art collaborative evaluation and treatment for patients with rare lung diseases. This reminds us that awareness of AIDS began in the United States in mid 1981, when a number of reports in medical journals documented the occurrence of unusual numbers of a rare form of aggressive cancer and a rare lung disease in young gay men in New York City and California. Bronchiolitis obliterans is a rare chronic lung disease that worsens over time. Rare lung diseases are diseases that affect fewer than 1 in 2000 people. 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. CT provides images with structural detail that compares with macroscopic histological examination. Quality assurance to minimize diagnostic variability also included central review of the available lung biopsies. By continuing you agree to the use of cookies. The 5-year mortality remains between 33% and 50% and is likely to vary based on the underlying disease process. Copyright © 2021 Elsevier B.V. or its licensors or contributors. A1PI = α1 proteinase inhibitor. The main risk related to contact with blood involves the sharing of needles, syringes, and other equipment for injecting drug use. Patients with idiopathic PAP typically have clinical symptoms of progressive dyspnea and cough with a chest radiograph that suggests an alveolar filling process. 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. de Wit, P.C.G. In many parts of the world, infection through blood and blood products is now effectively prevented. 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. Benign uterine smooth muscle cells spread hematogenously to the lung, the heart, lymph nodes, omentum, peritoneum, pelvic cavity, breast, bone, mediastinum, and nervous system. This complicates the performance and interpretation of imaging-based morphometry. A minority of patients may experience cough, dyspnea, and hemoptysis. 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 use of a treatment to promote structural repair, rather than to retard emphysema progression (as in AAT augmentation therapy), may influence the choice of methodological approach to reduce volume-related variability. Since IPF is a heterogeneous disease, it may be difficult to obtain clinically representative study populations. IPF Advisory Board sponsored by Boehringer Ingelheim corporate. It happens most often in people in the age range of 30 to 60 years. Although BML is usually diagnosed after an incidental finding on chest imaging, patients can present with mild pulmonary symptoms such as dyspnea on exertion and cough. 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. However, this collaboration is indispensable to these trials׳ success (Fig. Computed tomography of the chest in patients with LIP may reveal ground-glass opacities, centrilobular and subpleural nodules, and randomly distributed thin-walled cysts. Adam, in Encyclopedia of Human Behavior (Second Edition), 2012. 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. Thus, eligibility criteria and endpoints were defined on the basis of best available scientific evidence and advice. Subsequently, multiple studies have suggested that exogenously administered GM-CSF has a therapeutic benefit in some subjects with idiopathic PAP (161–163). Another issue is that local staff experienced in conducting clinical trials is needed as part of the administrative structure of the global trial. Densitometric analysis using semiautomated software. Pulmonary alveolar proteinosis (PAP) is a rare lung disease in which surfactant-rich lipoproteinaceous material accumulates within the alveolar space (154). 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. 10.6) [60]. 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. Furthermore, scanner manufacturer, model, settings, and protocols are known to influence Hounsfield values and, therefore, apparent voxel density values [47,48]. ), 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. Surfactant protein B (SPB) deficiency leads to respiratory distress on the first day of life, with death typically in the first six months, with the lungs of affected infants having a histopathologic pattern similar to that seen in idiopathic PAP (164). 61.4.5 Pulmonary Alveolar Proteinosis. Interstitial lung disease comes in more than 200 different types. A response-exposure curve with the shaded area representative of 90% confidence limits. Fig. Semiautomated software facilitates image analysis and reduces the inter- and intraobserver variability (and tedium) that plague visual scoring methods. Emphysema severity and distribution can be assessed on a single slice, as in this image from a subject with AATD in which the right and left lungs have been delineated in blue and red, respectively and low attenuation voxels (<−950 HU) have been highlighted in pink (Pulmo-CMS, MEDIS Medical Imaging Systems BV, Leiden, the Netherlands). This compared with estimates of up to 632 patients per arm over 3 years and up to 449 per arm over 5 years if efficacy was assessed using FEV1 [40]. For many years, whole-lung lavage remained the main therapeutic approach (154). A recent study of children and young adults with AT demonstrated an inverse relationship between serum interleukin (IL)-6 levels and vital capacity, suggesting that systemic inflammation is correlated with lower lung function in AT, although the mechanism is uncertain.31 In a large retrospective series, approximately one fourth of AT patients with chronic respiratory symptoms were found to have ILD, which has a unique histopathologic pattern and may be responsive to steroids if treated early in the course.32 Because of the known cellular and chromosomal sensitivity to ionizing radiation in AT, effort should be made to limit diagnostic radiation as much as possible. While planning the global IPF trials, BI sought expert support through establishing a steering committee (Fig. The European Respiratory Society (ERS) recently published a thorough statement on the multidisciplinary management of the respiratory manifestations of AT.29. 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. 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. 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. Earlier recognition of these diseases will lead to a better understanding of their pathogenesis and the development of newer treatments. Wegener's Granulomatosis. LAM lung disease (lymphangioleiomyomatosis) is a rare lung disease that tends to affect women of childbearing age. 10.5 and 10.6). Researchers in EMBL’s Zaugg group have studied the causes of pulmonary arterial hypertension (PAH), a rare disease that causes high blood pressure in the arteries of the lungs. A specific problem of global trials in rare diseases, including IPF, is poor recruitment. 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. Immunodeficiency in AT is variable, with both humoral and cellular abnormalities. Rare Lung Fungal Disease . The optimum method, which was a combination of statistical volume correction and endpoint analysis, achieved statistical significance (P = 0.049). In addition, a novel targeted assessment of regional density changes was employed in a post hoc analysis, which identified a gradient of treatment effect that was maximal, and statistically significant, in the lower lung. We use cookies to help provide and enhance our service and tailor content and ads. This variability also poses major challenges to the study׳s execution. A1PI = α1 proteinase inhibitor. 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. Values on the graphs are annual rates of decrease. Lung Diseases List. This issue is not just of methodological concern, since the conventional understanding that emphysematous damage reduces lung mass has been questioned. The disease is characterized by the emergence of cystic lesions and nodules in the lung parenchyma.106–108 Disease activity generally tracks with smoking status, and end-stage lung disease is predominantly seen in patients with ongoing tobacco use; however, rarely, disease progression occurs despite smoking cessation.109,110, PH seems to be frequent in PLCH. 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). [1-3] It can develop in virtually all organs, including the brain, lung, heart, liver, spleen, and bones. A recent study showed that inspiratory muscle training improved ventilatory pattern, lung volume, respiratory muscle strength, and the health and vitality domains for quality of life in patients with AT.33 A coordinated, multidisciplinary approach to monitoring and managing respiratory involvement in AT will likely result in improved respiratory health for these patients. A lack of standardization also prevents comparison between centers and studies. 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]. Pulmonary alveolar proteinosis, a rare lung disease, is caused by a build-up of material in the air sacs. 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. A pilot study of the use of CT densitometry suggested that a study of 130 patients over 3 years would be suitably powered to demonstrate treatment efficacy if CT were the outcome [49]. A. And because there is no cure, a diagnosis of pulmonary fibrosis can bring up a lot of emotions for both patients and caregivers. Translating the regulations and requirements as specified in the protocol into clinical conduct of the trial across all centers, countries, and regions represented another major challenge. Rare Lung Disease Clinic. To achieve high precision and uniformity of lung function measurements, the same spirometric equipment was used across all participating centers. Figure 10.6. *A1PI n = 92; placebo n = 85. Once the etiological agent was know, diagnostic tests could be developed and epidemiological studies could be conducted to assess prevalence, incidence and risk factors. Similar results were observed in mice deficient in the βc chain of the GM-CSF receptor (157,158). 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.
