How do I interpret heavy growth of Candida sp. from sputum of my patient with COPD and pneumonia?

Chances are our patient has been on antibiotics and is being treated with either inhaled and/or systemic corticosteroids which may all contribute to yeast overgrowth in the respiratory and GI tracts.   Fortunately, in the absence of severe immunocompromised state such as neutropenia,  Candida sp. in  respiratory specimens (including those obtained by bronchoscopy) is only rarely associated with pneumonia (1,2).   So no antifungal therapy seems to be indicated in our patient, unless oral candidiasis (e.g. either thrush or the atrophic variety) is also simultaneously present.  Time to examine the mouth!
