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. 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]. 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. LAM lung disease (lymphangioleiomyomatosis) is a rare lung disease that tends to affect women of childbearing age. 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. Computed tomography of the chest in patients with LIP may reveal ground-glass opacities, centrilobular and subpleural nodules, and randomly distributed thin-walled cysts. 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. 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. The Lung Association is here to help. 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. Rare cause of hypersensitivity pneumonitis (all causes other than farmer's lung disease and pigeon breeder's lung disease) Pulmonary arteriovenous malformations in hereditary hemorrhagic telangiectasia (HHT) Pulmonary manifestations of gastro-intestinal disorders pulmonary manifestations in inflammatory bowel diseases 10.7) but not on the imaging series acquired at functional residual capacity (FRC), or a combination of TLC and FRC imaging. [1,4] Congenital abnormalities in the developing lymphatic system are thought to play a major role in pathogenesis of the condition, with … 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. 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 main risk related to contact with blood involves the sharing of needles, syringes, and other equipment for injecting drug use. It is less clear whether this is also the best method to use in studies where therapy could alter lung compliance; this is arguably a treatment signal suggested by the physiological data in the REPAIR study [58] but the principle is equally applicable to other chronic lung diseases which are associated with changes in compliance, such as idiopathic pulmonary fibrosis. This issue is not just of methodological concern, since the conventional understanding that emphysematous damage reduces lung mass has been questioned. A number of densitometric indices derived from the lung voxel histogram have been advocated [43–46] (Figs. 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 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.

William E. Lawson, James E. Loyd, in Emery and Rimoin's Principles and Practice of Medical Genetics, 2013. EXACTLE generated similar results to the Dutch-Danish study that were also suggestive of a beneficial treatment effect on the rate of lung density decline. 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. Pulmonary transplantation remains a viable option for these patients. Following the alarming first reports, pubic health concerns rapidly increased as AIDS was also diagnosed in other communities in the United States, in particular people who inject drugs, people with hemophilia and Haitian migrants; very soon AIDS had also been reported in many others countries and in every continent. There are many types of lungs diseases which need to be taken care of in time as they may lead to fatal conditions. Copyright © 2021 Elsevier B.V. or its licensors or contributors. Case reports provide sporadic and incomplete information on the natural history of the disease and there are no diagnostic or standard treatment protocols. The pathogenesis of PLCH-PH is not well understood. 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. rheumatoid arthritis), occupational exposures (such … 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. 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. Generally the causes of these diseases are unknown. Figure 10.5. … A global clinical trial for rare diseases, such as IPF, faces additional, partly unknown challenges. Rare Lung Disease. A lack of standardization also prevents comparison between centers and studies. The platform is primarily aimed at patients and care Tanmay S. Panchabhai MD, ... Kristin B. Highland MD, MSCR, in Clinics in Chest Medicine, 2016. Sexual risk of HIV mainly results from vaginal–penile and anal–penile intercourse, and can be prevented by the consistent use of male or female condoms. 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). 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. 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. 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. Sexual transmission is by far the most important route for the spread of HIV globally. 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. Most cases are asymptomatic, and are most often diagnosed incidentally during intubation or bronchoscopy. They can be aggressive and their primary clinical manifestation in the lung may in fact represent a metastatic process. 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). 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. Another issue is that local staff experienced in conducting clinical trials is needed as part of the administrative structure of the global trial. Bronchitis. The disease affects adults more commonly than children, with a predilection for males. Diagnosing and caring for children with rare lung diseases is our specialty. 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. 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. 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 such, they may not be willing or capable of participating in another trial because of concurrent multiple overlapping or competing trials. 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. This cancer is rare in individuals under 40 years of age and extremely rare in children and adolescents. 1). The acquired or idiopathic form of PAP is the most common, but secondary and congenital forms occur as well. 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. Although it is difficult to establish the factors that underlie this prevention success at the global level, it is thought to at least in part reflect the effectiveness of ART, particularly for the prevention of mother-to-child-transmission (PMTCT). Rare Lung Disease Clinic. A modelled response-exposure curve was suggestive of a dose-effect (Fig. The disease is not benign despite the hypothesis that BML originates from uterine leiomyomas, a common neoplasm that has a prevalence of 3–20%. Figure 10.6. The molecular pathogenesis is complex but involves abnormal DNA damage responses leading to a high rate of intrachromosomal recombination and genomic instability. 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. The European Respiratory Society (ERS) recently published a thorough statement on the multidisciplinary management of the respiratory manifestations of AT.29. Asbestosis. Once the etiological agent was know, diagnostic tests could be developed and epidemiological studies could be conducted to assess prevalence, incidence and risk factors. 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. 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. 2). Similar results were observed in mice deficient in the βc chain of the GM-CSF receptor (157,158). Today, we know that there are three main ways in which HIV is transmitted: contact with blood, mother-to-child transmission, and sexual intercourse. 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. Consequently, where retardation of emphysema progression is the anticipated effect of antiproteolytic treatment, the optimal approach for reducing volume-related variability would appear to be the use of a statistical volume correction method to adjust lung density, measured from imaging acquired at full inspiration and expressed as a percentile index (as recommended by an expert working group [48] and currently employed in antitrypsin augmentation studies). 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. 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). Wegener's Granulomatosis. 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. Other conditions associated with endoluminal nodular lesions include endobronchial sarcoidosis, endobronchial granulomatous infections, papillomatosis, and tracheobronchial calcinosis. 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. Training courses were given by the vendor to familiarize institutional staff with their proper use, and a proficiency test had to be passed before the trial׳s start. 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 causes shortness of breath. 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. Voxel distribution histograms. Medical therapies to date have been ineffective due to the lack of clinical trials. However, this collaboration is indispensable to these trials׳ success (Fig. Experts at the US Centers for Disease Control and Prevention quickly suspected that this outbreak of co-occurring life threatening opportunistic infections possibly signaled a new disease caused by an infectious agent that might be sexually transmissible. Although evidence-based guidelines for the diagnosis and treatment of IPF have been issued [8], many aspects of the disease remain ill defined. 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). Worldwide, 5.2 million people received ART in 2009, a 30% increase compared to only 12 months earlier. If lung disease is taking your breath, you do not have to deal with it alone. SFTPC mutations can not only cause ILD in childhood but have also been associated with pediatric cases of PAP (21). Clearly, further studies are required to establish whether this is the correct interpretation. *A1PI n = 92; placebo n = 85. Lymphocytic interstitial pneumonia (LIP) is a rare lung disease on the spectrum of benign pulmonary lymphoproliferative disorders. Immunodeficiency in AT is variable, with both humoral and cellular abnormalities. A response-exposure curve with the shaded area representative of 90% confidence limits. 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. However, the practical difficulties of performing a randomized, placebo-controlled trial in a, (Permission for publication obtained from the Lancet. This complicates the performance and interpretation of imaging-based morphometry. Rare lung diseases are diseases that affect fewer than 1 in 2000 people. A. Patients with idiopathic PAP typically have clinical symptoms of progressive dyspnea and cough with a chest radiograph that suggests an alveolar filling process. While individual rare lung diseases affect less than 1 in 2000 individuals, collectively they have a significant impact upon the population at large. Tim Lahm MD, Murali M. Chakinala MD, in Clinics in Chest Medicine, 2013, PLCH is a rare lung disease that almost exclusively affects current or prior cigarette smokers. This Monograph comprehensively covers the most common and/or complex of these orphan lung diseases. The optimum method, which was a combination of statistical volume correction and endpoint analysis, achieved statistical significance (P = 0.049). Densitometric analysis using semiautomated software. Semiautomated software facilitates image analysis and reduces the inter- and intraobserver variability (and tedium) that plague visual scoring methods. 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. Rare Lung Disease Clinic. LIP is frequently associated with connective tissue diseases or infections. Rates of lung density decrease at total lung capacity versus trough therapeutic plasma alpha-1-antitrypsin levels. “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]. An accurate diagnosis requires the concerted expertise of a multidisciplinary team involving pulmonologists, radiologists, and pathologists [9], leaving uncertainties about the correct diagnosis in small centers and about consistency across centers. William E. Lawson, James E. Loyd, in Emery and Rimoin's Principles and Practice of Medical Genetics, 2013. In the French registry,35 most of the patients were diagnosed with PH at an average of 11 years after PLCH diagnosis, which is similar to the report by Fartoukh and colleagues.17 In both studies, patients were young (mean ages 39 and 45 years, respectively), and had an obstructive physiology with moderate to severe airflow obstruction (forced expiratory volume in 1 second [FEV1], 46% and 52% of predicted), air trapping, and maintained total lung capacity. CT provides images with structural detail that compares with macroscopic histological examination. Get Help. Thus, eligibility criteria and endpoints were defined on the basis of best available scientific evidence and advice. 2. 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. For many years, whole-lung lavage remained the main therapeutic approach (154). 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. A rare lung disease is one that affects fewer than 200,000 people in the United States. 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. C. 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. 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. Computed tomography reveals a pattern of ground glass opacification with intralobular and interlobular septal thickening. [1-3] It can develop in virtually all organs, including the brain, lung, heart, liver, spleen, and bones. 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]. It is likely that this failure to identify a significant treatment effect using the FRC series (and the combination of TLC and FRC imaging) relates to the reduced accuracy of expiratory imaging for the assessment of emphysema due to the confounding effects of air-trapping that will arise on expiration. while in the United States it is a disease that affects fewer than 1 in 200,000, at any given moment. Fig. Lung Diseases List. Facilities specialized in the treatment of such diseases are generally attractive candidates for clinical trials. 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). Figure 10.8. Demonstrating polyclonality with immunohistochemistry is the key to differentiating LIP from lymphoma. 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.

James S. Hagood MD, in, Kendig's Disorders of the Respiratory Tract in Children (Ninth Edition), HIV/AIDS: The Role of Behavior and the Social Environment in a Global Pandemic, Encyclopedia of Human Behavior (Second Edition), The diagnostic gold standard for the quantitative assessment of emphysema is histopathology, but tissue sampling requires invasive methods. Neuromuscular involvement, discoordinated swallowing, and impaired mucociliary clearance should be evaluated and managed, as for many patients susceptible to these disorders. This led to CT lung density measurements being used as an objective, noninvasive, direct assessment of emphysema in vivo. A rare disease is one that affects less than one person in every 2,000. 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. 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). 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. Here is a list of breathing disorders with information on symptoms, causes, treatment and disease management. 10.5 and 10.6). 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. 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. Figure 10.7. 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. 61.4.5 Pulmonary Alveolar Proteinosis. There are numerous possible causes of ILD, including connective tissue disorders, autoimmune diseases (e.g. Subsequently, multiple studies have suggested that exogenously administered GM-CSF has a therapeutic benefit in some subjects with idiopathic PAP (161–163).
