A retrospective evaluation of vitamin K for hemoptysis in adult cystic fibrosis patients.

Objectives: Hemoptysis is a complication in cystic fibrosis (CF) patients, and is associated with pulmonary exacerbations and hospitalizations. Pancreatic insufficiency is common in CF patients, and therefore these patients may benefit from the use of vitamin K therapy.

Methods: This was an observational study conducted in adult CF patients aiming to describe the utilization of vitamin K therapy in the setting of hemoptysis during an acute CF pulmonary exacerbation.
