Indications and duration of treatment vary depending on the form of DILD (see the section "Specific Characteristics of Different Forms of Diffuse Interstitial Lung Disease"). Mycetoma is a complication that may occur in patients with sarcoidosis who have destructive fibrotic pulmonary lesions. It is a vague appearance seen on a chest X-ray or CT. Interruption of treatment with the suspected drug. ­- Pulmonary hypertension. Chest radiography reveals reticular opacities, sometimes associated with honeycombing, with a basal and bilateral distribution. In many cases, the exposed individual inhales dust containing silicon dioxide and silicates in variable proportions or dust contaminated with asbestos fibers, which explains the variability of the histologic findings and of the clinical and radiological manifestations of the mixed forms of the disease. The clinical picture is the same as that of other forms of DILD. By plain chest radiograph, bilateral and symmetrical alveolar infiltrates may be seen, more marked in the perihilar zones (butterfly wings), but these may be predominantly peripheral or basal and, in some cases, are the only finding in asymptomatic patients. Translators working for the Journal are in charge of the corresponding translations. Prognosis. The disease usually presents as cough and exertional dyspnea. adj., adj catarac´tous. Arterial hypoxemia only becomes evident in the advanced stages of the disease, and hypercapnia in the final stages. Consequently, all current and past medications taken by the patient should be noted, including details of the dose and duration of treatment. lenticular cataract: [ kat´ah-rakt ] opacity of the lens of the eye or its capsule. If no improvement is observed, bilateral ovariectomy is recommended. Jason V, Brown KK, Cool CD, Young DA, Cherniak RM, King TE, et al.. The course of the disease is variable. Although it is relatively common to find subclinical alveolitis in BAL, the clinical and prognostic significance of this is uncertain. Analysis reveals material that is PAS positive and Alcian blue negative, a high concentration of total phospholipids (phosphatidylglycerol), and the presence of lamellar bodies visible on electron microscopic examination. Generally it is not resolved by chest drainage because of the rigidity of the lung parenchyma, which prevents the lung from re-expanding. 10/14/2020. Accepted for publication March 18, 2003. 128-33. Associated signs may include generally asymptomatic diabetes insipidus (28% of cases) and cystic bone lesions in the cranium, long bones, ribs, and pelvis. These are patients with few or slight symptoms and only slight lung functional abnormalities. Chest radiography and HRCT reveal nonspecific, nondiagnostic characteristics. HRCT findings (areas of airspace consolidation with a subpleural or peribronchial distribution) are a useful guide to diagnosis. Although no controlled trials have been carried out, treatment with high doses of corticosteroids (100-250 mg/day of intravenous methylprednisolone) has been shown to be effective in the exudative stage of the disease.31, Respiratory Bronchiolitis-Associated Interstitial Lung Disease, RB-ILD is a very rare clinicopathological entity characterized, as its name suggests, by respiratory bronchiolitis associated with DILD. It is not a substitute for professional medical advice, diagnosis or treatment and should not be relied on to make decisions about your health. It concerns alveolar epithelium, pulmonary capillary endothelium, basement membrane, and perivascular and perilymphatic tissues. Grupo de Investigaci?

This histological pattern can also be associated with other clinical entities (Table 10). Manuscripts will be submitted electronically using the following web site:, link which is also accessible through the main web page of Archivos de Bronconeumologia. Assessment of the Response to Treatment and Clinical Course of Diffuse Interstitial Lung Disease*, TABLE 9. Whenever possible, HRCT scans should be carried out before fiberoptic bronchoscopy. EAA is caused by exposure to organic agents, and pneumoconiosis by exposure to inorganic dust. BAL is not diagnostic and reveals lymphocytosis. However, in most cases it is impossible to identify any exacerbating cause, and acute respiratory insufficiency is attributed to the rapid progression of the disease. In any investigation of DILD a high resolution computed tomography (HRCT) scan should always be obtained. The radiologists and pneumologists who read radiographs and classify them according to the ILO guidelines require prior training. Role of HRCT in defining disease extent. WebMD does not provide medical advice, diagnosis or treatment. In IPF, histiocytosis X, asbestosis, and LAM, HRCT findings are considered to be diagnostic criteria. Neumopat? 1, 2A). It should be emphasized that a simple finding of a UIP pattern on histological examination of the lung parenchyma is not synonymous with a diagnosis of IPF. In a few cases, medical history, clinical signs, and radiographic results are not sufficient to establish a conclusive diagnosis. The patient's age at the time of presentation of the disease is usually greater than 50 years. 121-30. In pulmonary sarcoidosis, corticosteroids are effective in the short to medium term, but no evidence has been adduced to show that they modify the course of the disease.39 Treatment is not indicated in stage I because of the high incidence of spontaneous remission. Honeycombing is rare. Access to any published article, in either language, is possible through the Journal's web page as well as from PubMed, Science Direct, and other international databases. ?cnicas y Trasplante. The disease affects young adults smokers, and presents in the form of cough and progressive exertional dyspnea. Nodular opacities were defined as focal round opacities. Ground-glass opacities are abnormal findings on a CT scan of the lungs. 669-71. Hospital 12 de Octubre, Madrid, Spain. on Blood test results are of interest in the diagnosis of certain DILD (Table 3).1,2,7. Respiratory failure is the cause of death in 40% of cases. 1581-6. Can you get coronavirus from touching cash? In 25% of cases, LAM is associated with tuberous sclerosis, a hereditary disease characterized by multiorgan hamartomatosis.67,68 In the early stages of the disease, chest radiography and HRCT reveal micronodular pseudo-miliary opacities and B Kerley lines. The advantages of video-assisted thoracoscopy are the shorter operating time, fewer postoperative complications, and shorter length of stay in hospital. A history of lowered immunity and a microbiological analysis of BAL will generally confirm diagnosis. Detection of serum autoantibodies against GM-CSF is useful in the serological diagnosis of idiopathic alveolar proteinosis owing to its high sensitivity and specificity.74, Prognosis. 277-304. Treatment. Bilateral lung transplants should only be considered in cases where there is some doubt about the behavior of the remaining lung. The disease affects smokers with exposures of 30 pack-years or more. SEPAR. In cases of chronic pulmonary sarcoidosis and severe extrapulmonary sarcoidosis, other drugs have been used, such as antimalarial agents (a first line treatment for severe cutaneous and nasal sarcoidosis and hypercalcemia) and immunosuppressive agents, especially methotrexate and azathioprine. Other types diagnosed in Spain are aspartosis, mother-of-pearl lung, air conditioner alveolitis, ultrasonic humidifier lung, sausage-cleaners lung, suberosis, isocyanate lung, soy lung, and Candida lung.55-57, Clinical features. 862-9. If improve-ment is observed or alveolitis persists, continuation of treatment for another year is recommended.54, EAA, also known as hypersensitivity pneumonitis, is a form of DILD caused by the inhalation of organic agents, although inorganic substances (isocyanates) can also cause this disease. The two most characteristic findings of chest radiography (hilar lymphadenopathy and lung infiltrates) serve as a basis for staging the disease (Table 13).37. ­- Diffuse pulmonary hemorrhaging. Treatment. Treatment. Prognosis. Respiratory bronchiolitis, a lesion caused by smoking, is characterized by pigmented macrophage accumulation in the bronchioles. This is characterized by the presence of anti-Jo-1 antibodies in patients with polymyositis/dermatomyositis. In the case of asbestos, exposure can be confirmed using BAL.87 It is considered that the presence of 1 or more asbestos bodies per milliliter indicates a workplace exposure to this agent.11. It is accompanied by rapid clinical deterioration and respiratory insufficiency. This is established using HRCT findings, transbronchial biopsy and BAL (CD1+ cells >5% of cells of macrophage lineage). The predominant patterns of abnormality on HRCT were classified into ground-glass opacities, consolidation, reticular opacities, or nodular opacities. Clinical signs (anemia, hemoptysis), BAL results (the presence of hemorrhagic fluid and/or hemosiderophages), and the presence of immunological abnormalities (neutrophil anticytoplasmic antibodies, antinuclear antibodies, basal antimembrane antibodies) are generally sufficient to differentiate these cases from DILD. In the proliferative and fibrotic phases, traction bronchiectasis and honeycombing become apparent.32, Prognosis. A definitive diagnosis of IPF requires the presence of the histologic pattern of UIP. Some cataracts result from injuries to the eye, exposure to great heat or radiation, or inherited factors. It is characterized pathologically by the presence of diffuse alveolar damage. This tool does not provide medical advice. In some cases, onset is acute with severe respiratory insufficiency. Pulmonary alveolar microlithiasis: high-resolution CT and MR findings.. J Comput Assist Tomogr, 22 (1998), pp. HRCT shows diffuse, patchy, subpleural, reticular opacities with irregularly thickened interlobular septa and intralobular lines; subpleural honeycombing; and traction bronchiectasis.

Kerley B lines on the chest radiograph are due to interlobular septal thickening as a result of interstitial lung infiltrate along the lymphatics or lymphatic engorgement … SEPAR. Patients with secondary pulmonary hypertension can benefit from oxygen therapy and vasodilators. On rare occasions, lipoid pneumonia causes bilateral interstitial infiltrates. Patients with predominant reticular opacity or honeycombing usually progress despite treatment (81, 100-103). Clinical features. Xaubet A, Agustí C, Luburich P, Roca J, Ayuso MC, Marrades RM, et al.. Is it necessary to treat all patients with idiopathic pulmonary fibrosis?. Asociación Sudamericana de Cirugía Torácica (ASCT). Recurrence has been reported in cases of DIP, alveolar proteinosis, LAM, and sarcoidosis. Are you a health professional able to prescribe or dispense drugs? Clinical features. Prognosis. The treatment for acute eosinophilic pneumonia is high doses of methylprednisolone (1-2 mg/kg every 6 hours for 2 to 3 days), followed by a lower dose (0.5 mg/kg for 2 weeks) and gradual tapering of the dose until treatment is completed.81,84, This is a DILD caused by the inhalation of inorganic dust particles. Baltimore: Williams & Wilkins, 1998. Certain DILD primarily affect smokers. Diagnosis. BAL may preclude the need for lung biopsy in some DILD. 245-8, rd ed. Moreover, the term COP avoids confusion with airway diseases (constrictive bronchiolitis obliterans).4, Clinical features. Prognosis. Until a few years ago, NSIP was included under the generic term IPF, although it is now known that it is an entirely differentiated entity.4,29. Acute interstitial pneumonia. Onset of the acute form of this disease usually occurs between 2 and 8 hours after contact with the antigenic source and takes the form of dyspnea, cough, fever, asthenia, presternal chest tightness, joint and muscle pain, chills, and sweating. Reticular opacities were defined as linear opacities forming a mesh like pattern. In such cases, the dose should be increased to between 20 mg and 30 mg/day. The Journal is published monthly both in Spanish and English. Comparison of high-resolution computed tomography findings between survivors and non-survivors.. Am J Respir Crit Care Med, 165 (2002), pp. It is estimated that the prevalence of the disease is 20 cases per 100 000 for males and 13 cases per 100 000 for females, making it the most common form of DILD. Traction bronchiectasis, impaired ciliary clearance, and treatment with corticosteroids or immunosuppressive agents all make patients susceptible to respiratory infection caused by usual or opportunistic pathogens. Drugs can cause various forms of DILD: UIP, diffuse alveolar damage, organizing pneumonia, LIP, DIP, NSIP, pulmonary eosinophilia, and acute hypersensitivity pneumonitis. HRCT evidences ground glass patterns and areas of consolidation, which have been related to the exudative phase of diffuse alveolar damage. Systemic Involvement in Diffuse Interstitial Lung Disease, TABLE 3. Pulmonary thromboembolisms is responsible for the death of 3% to 7% of patients with DILD. These opacities usually responded quickly to treatment; however, those patients with lung fibrosis at presentation may have worse prognosis. However, as a result of the new classification of idiopathic interstitial pneumonias, several hospitals have analyzed the histopathological characteristics of cases of DILD associated with collagenosis and have observed that many cases recorded as UIP were in reality NSIP. 462 The typical appearance of honeycomb lung is shown in Figs. It is the recommended procedure when chest radiography findings are not diagnostic, or when associated diseases, such as tuberculosis, pulmonary neoplasia, or emphysema, are suspected. ? Causes can range from scarring from prior infections, trauma, fluid, infection, allergy, drowning, smoke inhalation, tumor, etc. Treatment. The effects these drugs have on the lungs are periodically updated on this web site. Diagnosis can generally be confirmed by BAL findings (staining of lipid vacuoles in the alveolar macrophages) and the findings of transbronchial or surgical lung biopsy. The S-100 antibody has also been used on lung biopsy samples to diagnose this condition.69,70, Prognosis. LIP is usually associated with other disorders, such as collagen diseases, autoimmune disorders (Hashimoto's disease, myasthenia gravis, pernicious anemia, primary biliary cirrhosis), and immunodeficiencies (agamma-globulinemia). Diminished aeration of lung; Associated with signs of volume loss; Causes of pulmonary opacity. The fact that the lung parenchyma is found to be normal does not rule out the possibility of DILD. These are symmetrical and basal ground glass opacities, sometimes associated with reticular patterns. The clinical and radiologic signs of each form of drug-induced DILD are similar to those of the idiopathic form of the same disease. Its incidence is difficult to estimate since the disease is often asymptomatic and dependent on a geographical area and ethnic group. The prognosis is worse for patients over 40 years old, black patients, and patients with symptoms that persist for more than 6 months, or when more than 3 organs are affected or there is concomitant lupus pernio. Transbronchial biopsies performed using a fiberoptic bronchoscope can confirm diagnosis in the following types of DILD: sarcoidosis, EAA. Computed axial tomography of the thorax is a more sensitive tool than chest radiography in the investigation of the abnormalities of the pulmonary interstitium. Drug-induced DILD may also be suspected because the clinical signs have disappeared when treatment with a particular drug is discontinued and reappeared on resumption of treatment. Hospital Vall d'Hebron, Barcelona, Spain. The prognosis is favorable, since the patient usually improves upon treatment with corticosteroids. 12135-9. M? Diagnosis. ?rea de T? The extent of lung fibrosis on CT is an important predictor of survival . Some 70% of patients are asymptomatic at the time of diagnosis. Transbronchial biopsy can reveal the histological changes characteristic of the disease.55,56, Diagnosis. Chest radiograph reveals a bilateral interstitial pattern with B Kerley lines. Diffuse interstitial lung disease (DILD) is a category comprising a series of entities with similar clinical, radiologic, and lung function presentations, in which the principal pathological alterations affect the interstitial alveolar structures. ­- Drug history. 571-7.

This consists of serial therapeutic BAL, which are indicated in cases of progressive disease.75,76 Recently, some authors have reported on cases treated with GM-CSF with good results.77, Alveolar microlithiasis is a rare disease of unknown etiology, characterized by the presence of calcified bodies (microliths) inside the alveolar spaces. More than 150 different causes are currently known, although identification of the causal agent is only possible in approximately 35% of cases. They are hazy areas that do not obscure the underlying structures of the lung, such as the bronchial airways and blood vessels. 10-7. How Long Does Coronavirus Live On Surfaces? by The most common forms of EAA are poultry-workers lung and farmer's lung. The presence of this antibody has been associated with a better response to treatment.51 Patients with systemic sclerosis often present a positive Scl-70 antibody titer.46, Diagnosis.

However, when ground glass patterns are found in conjunction with reticular patterns, they may be indicative of conglomerate masses rather than inflammation. With respect to the question of monitoring the course of the disease and the patient's response to treatment, the ERS and ATS have issued consensus statements defining criteria for sarcoidosis and IPF, which may be used in a general way for other DILD. In the advanced stages of IPF and other DILD that progress to fibrosis, pulmonary hypertension and cor pulmonale develop in 70% of patients and are the cause of death in 30% of cases. However, some cases may progress to fibrosis. Interstitial lung diseases. Combining assessment of imaging features with clinical and laboratory findings could facilitate early diagnosis of COVID-19 pneumonia. ?rea de T? Dr. J. Ferrer (Hospital Vall d'Hebron, Barcelona) collaborated in the section on pneumoconiosis. In an attempt to standardize the diagnosis of EAA as much as possible, a series of criteria have been proposed (Table 18).60 The diagnosis is confirmed if 4 major criteria and at least 2 of the minor criteria are fulfilled. Iloprost (an analog of prostaglandin I2) may be an effective treatment. Treatment. Focal airspace disease. on.

Am J Respir Crit Care Med, 160 (1999), pp. IPF is usually diagnosed in patients over 50 years old. Onset of dyspnea is usually gradual but progressive, and for some time it may be the only symptom. Honeycomb lung is characterized by coarse reticular interstitial opacities with intervening lucent spaces. ?as intersticiales difusas. (Courtesy of C. Isabela Silva, MD, and Nestor Müller, MD.) Indications for Lung Transplant in Diffuse Interstitial Lung Disease, TABLE 7. Azathioprine is recommended as a first choice, and methotrexate as a second choice. Cardiopulmonary transplant is only indicated for young patients with right refractory cardiac failure, a very rare occurrence. This is based on the existence of a clinical picture and radiographic results consistent with this diagnosis in conjunction with a prior history of exposure to potentially causal inorganic agents. Chest radiographs reveal alveolar patterns, and extensive ground glass opacities are apparent on HRCT scans. LAM is characterized by the abnormal proliferation of smooth muscle cells and may affect, in addition to the lungs (smooth peribronchiolar, perivascular, and perilymphatic muscle), other organs, such as the kidneys, peritoneal lymphatics, liver, uterus, and pancreas.63-66. Moreover, there are no well-defined criteria that establish whether a given clinicopathological picture is caused by a drug. Reticular—fine or coarse linear shadows; Reticulonodular; Nodular—small (2 to 3 mm), medium, large, or masses (>3 cm) 3. The disease remits spontaneously in 25% of cases, although it can progress to respiratory failure. ?rea de T?

A Case Control Etiologic Study of Sarcoidosis (ACCES) Research Group. This should be established by surgical lung biopsy. Alternatives to Corticosteroid Therapy, TABLE 16. ?dica Panamericana, 1996. These abnormalities are as follows: reticular patterns, irregular septal thickening, traction bronchiectasis, and bibasilar, subpleural, and symmetrical honeycombing. ­- Occupational and work history. Transparietal needle biopsy should not be used because of the small size of the lung sample obtained with this technique and the high incidence of secondary pneumothorax. This imaging technique facilitates detection of the disease in patients with a normal chest radiograph. Some 90% of patients die, and neither mechanical ventilation nor treatment with high doses of corticosteroids has been shown to have any beneficial effect.13. It is advisable to monitor the evolution of all patients for 3 years after remission of the disease or the end of treatment since recurrence is observed in 10% of cases.37,38. ?o, Seville, Spain. Clinical Value of Bronchoalveolar Lavage (BAL) in Diffuse Interstitial Lung Diseases (DILD), TABLE 6. There is a frequent association (60% of cases) with renal angiolipomas. Examination of the lung biopsy reveals diffuse alveolar damage or organizing pneumonia in addition to the abnormalities typical of the underlying disease. The radiographic features associated with DILD are ground glass opacities; reticular, small nodular, and reticulonodular patterns; and honeycombing. In the case of relapse, it may be necessary to modify or restart the regimen and maintain an effective dose. The term AIP should be used exclusively for cases of idiopathic acute respiratory distress syndrome. The Journal expresses the voice of the Spanish Respiratory Society of Pulmonology and Thoracic Surgery (SEPAR) as well as that of other scientific societies such as the Latin American Thoracic Society (ALAT) and the Iberian American Association of Thoracic Surgery (AICT). Although some authors have made a case for the usefulness of scintigraphy using 99Tc-DTPA (diethylene triamine pentaacetate) to assess epithelial permeability and the evolution of DILD, available data is too meager to recommend its use. A recurrence of the disease occurs in 50% to 60% of patients, typically 6 to 12 months after start of treatment when the dose of corticosteroids has usually been reduced to 10 mg or less. Apart from the symptoms typical of DILD, other signs of this disease are: recurrent pneumothorax (69%), chylothorax (23%), hemoptysis (20%), and less often, ascites, pericardial pleural effusion, chyloptysis, and chyluria. The prognosis is variable since the disease may remit spontaneously, remain stable, or progress to pulmonary fibrosis. The decision regarding which other organs should be biopsied will depend on which organs are affected. The patient can also be exposed directly to the antigen source for 5 days. Prognosis. In addition, certain clinical entities can be associated with pulmonary eosinophilia, although this is rare and is not one of the predominate characteristics of the clinical picture. If symptoms and/or radiographic or lung function abnormalities persist, corticosteroids should be administered at the dosage regimen used in NSIP.4, This is an entity characterized by intra-alveolar macrophage accumulation. The presence of Birbeck granules visible under electron microscope in the BAL and transbronchial biopsy is a diagnostic sign. 335-40, Am J Resp Crit Care, 155 (1998), pp. The diagnostic criteria for allergic bronchopulmonary aspergillosis are different in the United Kingdom and the USA. ­- Radiotherapy. Sociedad Española de Neumología y Cirugía Torácica (SEPAR). During the past few weeks, he received multiple courses of oral antibiotics without improvement for a diagnosis of pneumonia. Exercise testing and the 6-minute walk test do not have to be performed in all cases of DILD. Prognosis. SEPAR. The ATS/ERS have established guidelines concerning the therapeutic regimen that should be used (Table 11).3 This takes the form of the corticosteroid therapy administered in combination with cyclophosphamide or azathioprine. Treatment. COP can be idiopathic or associated with collagenosis, infections, medication, or radiotherapy. 794-9. Dr. J.

Most patients present with dry cough. In cases with characteristic clinical signs and a temporary contact with a suspected antigen source, diagnosis can be established with some certainty. Chest radiographs and HRCT scans show thickening of the walls of the bronchi and ground glass or small reticulonodular patterns. We gradually tapered prednisolone doses and her medical condition had been well-controlled by immunosuppressive treatment over 15 years since the diagnosis (Figs. As for CT findings, the reticular opacities and GGOs diminished. As a general guideline, the following are recommended (Table 8): -­ Assessment of symptoms (in particular dyspnea, using validated scales).
