Patient #4, a 67 year old male with a history of hypersensitivity pneumonitis and pulmonary fibrosis. He underwent bilateral lung transplantation in October 2016. His post-transplant course was complicated, including the development of two episodes of multidrug resistant Pseudomonas aeruginosa pneumonia. Bacteriophage therapy was administered via nebulizer and intravenously, along with adjunctive systemic antibiotics. Therapy was well tolerated without any attributable adverse events. Both episodes of pneumonia resolved, and the patient’s respiratory status improved. Patient was discharged from the hospital infection-free.
