Abstract

Fibrotic hypersensitivity pneumonitis (f-HP) is an interstitial lung disease in which various antigens in susceptible individuals may play a pathogenetic role. This study evaluates the role of transbronchial lung cryobiopsy (TBLC) and bronchoalveolar lavage (BAL) in identifying a UIP-like pattern and its association with fibrosis progression. We conducted a multicentre retrospective cohort study of patients diagnosed with f-HP who underwent BAL and TBLC between 2011 and 2023. A UIP-like pattern was defined by the presence of (A) patchy fibrosis and fibroblastic foci or (B) honeycombing ± (A). We investigated BAL's role in predicting UIP-like patterns within a clinical-radiological-serological framework, examining disease progression in these patients using spirometry and mortality data. A total of 195 patients were enrolled, 59 (30%) of whom exhibited a UIP-like pattern. These patients showed greater lung function decline, lower BAL lymphocytosis (14.4% vs. 37.4%, p < 0.001), higher nintedanib prescription (35% vs. 14%, p < 0.001), and higher 10-year mortality (HR 2.8, 95% CI 1.3-5.8, p = 0.004). f-HP patients with a UIP-like pattern exhibit worse clinical outcomes and higher mortality. In cases of low BAL lymphocytosis with a high pre-test clinical suspicion of f-HP, lung biopsy may not be necessary as it increases the likelihood of identifying a UIP-like pattern.

纤维化超敏性肺炎低温活检UIP模式的临床意义:一项多中心回顾性研究。
纤维化超敏性肺炎(f-HP)是一种肺间质性疾病,易感个体的多种抗原可能起致病作用。本研究评估了经支气管肺低温活检(TBLC)和支气管肺泡灌洗(BAL)在识别uip样模式及其与纤维化进展的关系中的作用。我们对2011年至2023年间接受BAL和TBLC的f-HP患者进行了一项多中心回顾性队列研究。(A)斑片状纤维化和成纤维细胞灶或(B)蜂窝状±(A)为upp样模式。我们研究了BAL在临床-放射学-血清学框架内预测upp样模式的作用,使用肺活量测定法和死亡率数据检查这些患者的疾病进展。共纳入195例患者,其中59例(30%)表现为uip样模式。这些患者表现出更大的肺功能下降,BAL淋巴细胞减少(14.4% vs. 37.4%, p p p = 0.004)。具有upp样模式的f-HP患者表现出更差的临床结果和更高的死亡率。对于低BAL淋巴细胞增多而检测前临床怀疑为f-HP的病例,肺活检可能不需要,因为它增加了识别upp样模式的可能性。
