Abstract:
Objective To describe the clinical features of invasive fungal disease in Huashan Hospital,Fudan University from January 2004 to December 2006.Methods The medical data were reviewed retrospectively for the patients with fungal infection, which was confirmed by positive fungal culture or microscopic examination with blood,sterile body fluid,deep tissue,sputum specimen or isolation of Aspergillus spp.and Cryptococcus spp.from bronchoalveolar lavage.The proven and probable cases of invasive fungal disease were included in this analysis.Results A total of 111 patients were diagnosed as invasive fungal dis-ease,including 104 proven cases and 7 probable cases.Sixty-one cases were community-acquired and the other 50 were nosoco-mial.The most common site of infection was bloodstream (51,45.9%),followed by central nervous system (44,39.6%)and respiratory system (14,12.6%).The most common pathogens were Candida spp.(50,45%),Cryptococcus (47,42.3%) and Aspergillus spp. (12, 10.8%). The community-acquired fungal infections were mostly found in central nervous system (44,72.1%),and respiratory system (12, 19.7%),mainly caused by Cryptococcus and Aspergillus. The nosocomial fungal infections occurred primarily in blood-stream (96.0%),mainly due to Candida spp.No underlying disease or risk factor was identified in more than half of the pa-tients with community-acquired infection,while almost all the patients with nosocomial fungal infection had underlying disease and predisposing factors.Indwelling venous catheter was closely associated with nosocomial bloodstream infection.Indwelling venous catheter lasted for more than 1 week in 64.7% of the patients with Candida bloodstream infection.The same fungal strain was isolated from both the cather and blood of the same patient in 11 cases.The overall mortality of these invasive fungal diseases was 14.4% (16/111).The mortality rate was 18.0% (9/50)in the patients with nosocomial invasive fungal infection, and 11.5% (7/61)in the patients with community-acquired invasive fungal infection.Conclusions The most common site of in-vasive fungal infection is bloodstream,followed by central nervous system,and respiratory system.Majority of the fungal patho-gens are Candida spp.,Cryptococcus and Aspergillus spp.The community-acquired invasive fungal disease is primarily meningitis caused by Cryptococcus.The nosocomial invasive fungal disease is mainly bloodstream infection caused by Candida spp.
