Managing Cavitary Coccidioidomycosis Expert Opinions for Improving Patient Outcomes.

Abstract

Coccidioidomycosis, caused by the dimorphic fungi Coccidioides immitis and Coccidioides posadasii, is recognized as an increasing threat both nationally and worldwide. This is in large part secondary to the expanding range of Coccidioides species and increased international travel to endemic regions. Most individuals exposed to airborne Coccidioides organisms do not need medical attention, but approximately 30% will demonstrate primary pulmonary coccidioidomycosis with signs and symptoms that mimic community-acquired pneumonia or other respiratory illnesses. Further, 5% of those with a diagnosis of pulmonary coccidioidomycosis will demonstrate serious and even life-threatening manifestations, including extrapulmonary or disseminated coccidioidomycosis. Of those who demonstrate pulmonary coccidioidomycosis, past evidence suggests that approximately 5% to 15% will experience long-term pulmonary sequelae in the form of nodules, abscesses, or cavitary lesions. These lesions may not be easily distinguished from malignancy or other infections, such as TB, and they add a substantial burden to both patients and the health care system. Despite the long-term consequences of cavitary coccidioidomycosis in some individuals, the current literature review and practice guidelines demonstrate a paucity of clear management strategies to treat these patients. In this report, we focus on cavitary lesions in coccidioidomycosis with the goal of presenting a description of the evaluation and management of their various forms, manifestations, and complications. These recommendations are derived from a multidisciplinary group of experts.
