Acute exacerbation (AE) of idiopathic pulmonary fibrosis (IPF) presents as episodes of acute respiratory worsening closely associated with endothelial damage and disordered coagulopathy. Recombinant human soluble thrombomodulin (rhTM) regulates the coagulation pathway mainly by reducing thrombin-mediated clotting and enhancing protein C activation. We investigated the efficacy of rhTM for the treatment of patients with AE-IPF. ⋯ We found that rhTM therapy improved 3-month survival of AE-IPF. The results observed here warrant further investigation of rhTM in randomized control trials.

Active smoking is associated with elevated thrombotic risk. Smoking status has recently been incorporated into the SAMe-TT2R2 (sex female, age < 60 years, medical history [more than two comorbidities], treatment [interacting drugs, eg, amiodarone for rhythm control], tobacco use [doubled], race [doubled]) score that can help predict poor international normalized ratio control in patients with atrial fibrillation (AF) treated with vitamin K antagonists (VKAs). The clinical benefit of antiplatelet therapy (APT) has been seen primarily in smokers. We hypothesized that active smoking may differently influence the risks of stroke and bleeding in patients with AF treated with VKAs or with APT. ⋯ In AF, there was a higher risk of severe bleeding in smokers, mainly in those treated with VKAs.
