Abstract
Background: Scedosporium fungal infection is an emerging disease which is difficult to diagnose and treat. Patients undergoing lung transplant may be colonized prior to transplantation and are at risk for lethal allograft infection after transplantation.
Objectives: To identify and evaluate treatment options.
Methods: This study is a retrospective review of patients treated at a tertiary academic medical center from 2007 to 2017 with positive sinonasal cultures. A review of the literature was also performed to identify additional cases.
Results: Two lung transplant patients had a positive culture for Scedosporium. The literature search resulted in 37 citations, which yielded only 2 prior cases of Scedosporium paranasal sinus colonization or infection in lung transplant recipients. Three of the 4 patients had cystic fibrosis. Two of the patients were colonized before initial transplant, while 1 patient was colonized before subsequent transplant. Three of the 4 patients survived, and all 3 had disease isolated to their sinuses and lungs treated with sinus surgery, while the fourth had disseminated disease and did not undergo sinus surgery. All patients were treated with multiple antifungals due to resistance patterns. One surviving patient cleared both sinus and lung cultures in less than 1 month, while the other 2 surviving patients achieved negative cultures after a minimum of 6 months.
Conclusions: Surgery may be especially important in patients with fungal sinus colonization or infection before or after lung transplantation. Chronic sinusitis is an important source for persistent fungal colonization and reinfection of the allograft which could be removed with surgical debridement before causing highly morbid pulmonary disease.
