Auscultation of Velcro crackles has been proposed as a key finding in physical lung examination patients with interstitial diseases (ILDs), especially idiopathic pulmonary fibrosis (IPF). However, no studies have carried out to assess the association other clinical variables. We evaluated cohort 132 patients, prospectively and consecutively included our ILD diagnostic program at tertiary referral center. All were auscultated during examination. The divided into 2 groups: “presence” or...

Acute exacerbation (AE) of idiopathic pulmonary fibrosis (IPF) is defined as a sudden acceleration the disease with appearance infiltrates superimposed on characteristic pattern IPF that leads to significant decline in lung function. It has high in-hospital mortality rates, despite medical treatment systematic steroids. We sought investigate whether there were differences according clinical stratification (AE, suspected AE, or AE known cause) and/or systemic reviewed characteristics and...
