The aim of this study was to investigate the relationship between fungal exposure prior to hospitalisation and ensuing onset of invasive mould infections (IMI) in patients at risk. Patients admitted to the Department of Haematology, Oncology and Transplant Surgery of the Medical University Innsbruck received a questionnaire regarding fungal exposure prior to hospital stay. Questions inquired heavy fungal exposures up to 5 days before hospitalisation. A total of 234 patients were enrolled in this study. Multiple fungus exposures were associated with the onset of community-acquired IMI in patients with haematological malignancies. In univariate analysis, haematological malignancies (P = 0.013) and allergy to dust, pollen or moulds (P = 0.015) were significantly associated with fungal infections. In multivariate analysis, logistic regression showed that haematological patients (P = 0.015) and patients with allergy (P = 0.015) were significantly more frequently infected with fungi. Hospital-independent fungal sources highlight risk-factors for IMI in severe immunocompromised patients and the rate of community-acquired IMI does increase., (© 2011 Blackwell Verlag GmbH.)

Invasive aspergillosis (IA) is a severe complication in the post-transplant period in recipients of solid organs. Therefore, early diagnosis and specific therapy of fungal infections in these patients are indispensable. We report the case of a 49-year-old patient, who suffered from IA after cardiac transplantation, which was complicated by post-transplant right heart failure requiring mechanical circulatory support using veno-arterial extracorporeal membrane oxygenation and a right ventricular assist device. Despite antifungal treatment, the patient died 3 weeks after transplantation because of multi-organ failure secondary to IA. The isolated Aspergillus strains exhibited in vitro resistance to caspofungin. [ABSTRACT FROM AUTHOR]
