ABSTRACT

Introduction:

Antifibrotic drugs, including nintedanib and pirfenidone, are approved for the treatment of idiopathic pulmonary fibrosis (IPF). Pirfenidone blocks the synthesis of TGF-beta and does appear to increase the risk of CV or bleeding events. Nintedanib is a Vascular Endothelial Growth Factor Receptors (VEGFR) inhibitor and may increase the risk of bleeding. Bleeding events were reported in 10% of patients in clinical trials (despite excluding patients at risk of bleeding including those on con-current anticoagulation (AC) or antiplatelet (AP) therapy. Consequently, nintedanib is relatively contraindicated for patients with IPF on anticoagulation or antiplatelet therapy. However, results from real-life data demonstrate that 17.8% of our patients with IPF are on anticoagulation or antiplatelet therapy. The overall incident of bleeding events in those patients taking either or with nintedanib is similar to that reported for Nintedanib alone. We describe two patients with antifibrotic and anticoagulation therapy to highlight how to manage these patients. Case 1. A 67-year-old female with history of acute pulmonary embolism secondary to COVID-19 on anticoagulation therapy presents for workup of acute respiratory distress syndrome or suspected exacerbation of underlying IPF-usual interstitial pneumonia. Patient treated as IPF with pirfenidione. Case 2. A 69-year-old man with a history of atrial fibrillation on anticoagulation therapy presents for follow-up of progressive fibrosing interstitial lung disease secondary to hypersensitivity pneumonitis. Nintedanib initiated for progressive fibrosing lung disease.

Discussion:

Concomitant use of anticoagulation and/or antiplatelet therapy with antifibrotics doesn't increase bleeding risk. Conclusion. Anticoagulation and/or antiplatelet therapy should not be a reason to withhold antifibrotic therapy in patients with IPF.
