    Background: Airway-centered Interstitial Fibrosis (ACIF) is a common pathologic pattern observed in our practice.Objectives: the objectives of this study are to describe the causes associated with ACIF in a large sample of patients and its effect on survival.Methods: A retrospective study in three centers of interstitial lung disease in São Paulo, between January of 1995 and December of 2012. the surgical lung biopsy specimens were reviewed by three pathologists. the clinical, functional and tomographic findings were analyzed by a standardized protocol.Results: There were 68 cases of ACIF, most of them women. the mean age was 57 +/- 12 yr. Dyspnea, cough, restrictive pattern at spirometry and oxygen desaturation at exercise were common. A reticular pattern with peribronchovascular infiltrates was found in 79% of the cases. the etiologies of ACIF were hypersensitivity pneumonitis in 29 (42.6%), gastroesophageal reflux disease in 17 (25.0%), collagen vascular disease in 4 (5.9%), a combination of them in 15 cases and idiopathic in 3 (4.4%). the median survival was 116 months (95% CI = 58.5 - 173.5). Lower values of oxygen saturation at rest, presence of cough and some histological findings - organizing tissue in the airways, fibroblastic foci and microscopic honeycombing - were predictors of worse survival.Conclusions: ACIF is an interstitial lung disease with a better survival when compared with IPF. the main etiologies are HP and GERD. the oxygen saturation at rest, the presence of cough and some histological findings are predictors of survival.

    Objetivo: Analisar as diferenças histopatológicas entre os lobos pulmonares submetidos a biópsia cirúrgica de pacientes com fibrose pulmonar idiopática. Métodos: Foram incluídos 16 pacientes com resultados de biópsias concordantes de dois sítios pulmonares, o lobo médio ou o segmento lingular. Técnicas semiquantitativas foram utilizadas na avaliação histológica pulmonar, aplicando-se um escore com base nas alterações encontradas no padrão histológico de pneumonia intersticial usual (PIU). Resultados: Encontrou-se maior incidência de foco fibroblástico em lobo inferior esquerdo e maior volume médio dos fragmentos pulmonares originários do lobo médio. Nenhuma diferença significante, que viesse a mudar o estadiamento da doença, e independentemente do local de origem da biópsia, foi encontrada. Conclusão: Não há dados que fundamentem a rejeição ao uso dos lobos médios e segmentos lingulares na investigação histológica de doenças intersticiais, em especial a fibrose pulmonar idiopática..
