Nebulized Bacteriophage in a Patient With Refractory Lung Disease

Abstract

An elderly man with refractory lung disease previously developed anti-phage neutralizing antibodies while receiving intravenous phage therapy. Subsequent phage nebulization resulted in transient weight gain, decreased C-reactive protein, and reduced burden. Weak sputum neutralization may have limited the outcomes, but phage resistance was not a contributing factor.
