interstitial lung disease diagnosis

Idiopathic pulmonary fibrosis: diagnosis and treatment: international consensus statement. Pulmonary hypertension, which is common in patients with IPF and pulmonary Langerhans cell histiocytosis, does not appear to correlate necessarily with the severity of impairment in pulmonary function or gas exchange. Sarcoidosis is more common in younger adults and generally has a more benign prognosis. The definitions and diagnostic criteria for several major forms of ILDs have been revised in recent years. The clinical evaluation of a patient with ILD includes a thorough medical history and detailed physical examination; obligatory diagnostic testing includes laboratory testing, chest radiography, and high-resolution computed tomography and comprehensive pulmonary function testing and blood gas analysis. Hypersensitivity pneumonitis: current concepts and future questions. Although some authors may argue that CTD is not a specific “cause” of ILD, identification of an underlying CTD clearly is relevant to evaluating, treating, and determining a prognosis for patients with ILDs. The degree of dyspnea is linked to disease severity and prognosis. Therefore joint pain and swelling (rheumatoid arthritis), cutaneous thickening, Raynaud phenomenon and dysphagia (systemic sclerosis), oculocutaneous albinism and colitis (Hermansky-Pudlak syndrome), chronic granulomatous sinusitis (GPA and Churg-Strauss syndrome), renal failure (Goodpasture syndrome), renal angiomyolipoma (lymphangioleiomyomatosis), and Crohn disease should be carefully asked about and sought for. Pulmonary function testing in patients with ILDs typically reveals a restrictive pattern with reduced diffusing capacity. Anatomic distribution and histopathologic patterns in diffuse lung disease: correlation with HRCT [published correction appears in. Interstitial lung disease can be challenging to diagnose. The definitions and diagnostic criteria for several major forms of ILDs have been revised in recent years. Bronchoalveolar lavage findings can be helpful in diagnosing ILDs such as pulmonary alveolar proteinosis and pulmonary Langerhans cell histiocytosis. Only a limited number of ILDs can be diagnosed by histologic findings alone, and even then, the clinical context and radiologic findings cannot be ignored in formulating management decisions. Adult patients with newly detected interstitial lung disease (ILD) of apparently unknown cause are clinically suspected of having idiopathic pulmonary fibrosis(IPF) if … There are between several dozen and over 200 interstitial lung diseases (ILDs), depending on how they are classified. For approximately 10% of patients with ILDs, a chest radiograph may look normal, particularly early in the course of disease. Of special interest in this context is the family history as it becomes more and more clear that a considerable subset of patients and diseases do have hereditary traits. The influence of cigarette smoking on lung function in patients with idiopathic pulmonary fibrosis. (2) How did the disease develop over time to the present? Pulmonary hypertension in interstitial lung disease. When a specific diagnosis can be made confidently on the basis of the clinical context, the tempo of the pathological process, and the findings on HRCT, a lung biopsy is usually not required. Histopathologic variability in usual and nonspecific interstitial pneumonias. Idiopathic pulmonary fibrosis: current concepts. In early ILD, however, the only abnormality, if any, on pulmonary function testing may be a mildly reduced diffusing capacity. The image, which was taken at the level of the bronchus intermedius, shows extensive subpleural honeycombing bilaterally, allowing for the confident diagnosis of UIP. The decision regarding surgical lung biopsy may need to be revisited during the subsequent clinical course, particularly if signs of progressive lung disease appear. | RACGP In the diagnosis of ILD, HRCT provides critical data needed to determine whether specific blood tests, bronchoscopic procedures, and surgical lung biopsy are necessary. The diagnostic strategy in a patient with ILD is based on considerations regarding the dynamic time course (acute, subacute, chronic), the cause (known or unknown), and the context of the disease at presentation (presence of extrapulmonary/systemic disease manifestations).
