ABSTRACT
The guideline for diagnosis and treatment of adult community-acquired pneumonia (CAP) (2007 edition) jointly formulated by the Infectious Diseases Society of America ( IDSA) and the American Thoracic Society ( ATS) has a great impact on the clinical management for CAP in China.In October 2019, the two societies revised and updated the guide again.Compared with the 2007 guideline, the new guideline is more concise ; some contents were deleted and some contents have been updated.The main updated points are obvious changes in the compiling mode , the reduced recommendation intensity for macrolides in CAP treatment ,and more emphasizing the relevance of diagnosis and treatment activities to the clinical practice.
ABSTRACT
Abstract The diagnosis of idiopathic interstitial pneumonias (IIPs) involves a multidisciplinary scenario in which the radiologist assumes a key role. The latest (2013) update of the IIP classification by the American Thoracic Society/European Respiratory Society proposed some important changes to the original classification of 2002. The novelties include the addition of a new disease (idiopathic pleuroparenchymal fibroelastosis) and the subdivision of the IIPs into four main groups: chronic fibrosing IIPs (idiopathic pulmonary fibrosis and nonspecific interstitial pneumonia); smoking-related IIPs (desquamative interstitial pneumonia and respiratory bronchiolitis-associated interstitial lung disease); acute or subacute IIPs (cryptogenic organizing pneumonia and acute interstitial pneumonia); rare IIPs (lymphoid interstitial pneumonia and idiopathic pleuroparenchymal fibroelastosis); and the so-called "unclassifiable" IIPs. In this study, we review the main clinical, tomographic, and pathological characteristics of each IIP.
Resumo O diagnóstico das pneumonias intersticiais idiopáticas (PIIs) envolve um cenário multidisciplinar no qual o radiologista assume papel fundamental. A última atualização (2013) da classificação das PIIs pela American Thoracic Society/European Respiratory Society propõe algumas mudanças importantes em relação à classificação original de 2002. Dentre as novidades, destacam-se o acréscimo de uma nova doença (fibroelastose pleuroparenquimatosa idiopática) e a subdivisão das PIIs em quatro grupos principais: PIIs crônicas fibrosantes (fibrose pulmonar idiopática e pneumonia intersticial não específica); PIIs relacionadas ao tabagismo (pneumonia intersticial descamativa e bronquiolite respiratória com doença intersticial pulmonar); PIIs agudas/subagudas (pneumonia em organização e pneumonia intersticial aguda); PIIs raras (pneumonia intersticial linfocítica e fibroelastose pleuroparenquimatosa idiopática); além das ditas "inclassificáveis". Foram revisadas, de forma didática neste estudo, as principais características clínicas, tomográficas e patológicas de cada uma das PIIs.
