A multidisciplinary working group devoted to epidemiological surveillance of invasive aspergillosis (IA) was created in January 2000 in Grenoble University Hospital. This article presents the results of a three-year IA surveillance. The multidisciplinary working group surveyed all hospitalized patients, and the mycology laboratory detected most suspected IA cases. Cases were reviewed monthly by the Aspergillosis Committee, and were classified according to international consensus criteria. Possible nosocomial acquisition was determined. Among the 490 alerts, 74 IA cases were observed: six proven cases (8%), 36 (49%) probable cases and 32 (43%) possible cases. The incidence was 4.4 (95% CI 3.4-5.4) IA/100 000 patient-days. Among the proven and probable IA cases, we observed 10 nosocomial cases and six cases of undetermined origin. No cases were noted in the protected rooms in the haematology unit. Only one cluster of cases (three nosocomial cases) was detected in the haematology unit. Forty-three percent of cases (N=32) were hospitalized in the haematology unit, and all other cases were hospitalized elsewhere. This three-year survey found a high rate of non-nosocomial IA cases and a high frequency of IA cases hospitalized in units other than haematology. Thus, this study shows the importance of IA surveillance in haematology units and all high-risk units.
BACKGROUND: Invasive aspergillus is a rarely reported infection in patients with solid tumors. CASE: A 59-year-old woman developed invasive pulmonary aspergillus after surgical debulking of an advanced ovarian adenocarcinoma and initiation of adjuvant combination chemotherapy. CONCLUSION: Invasive pulmonary aspergillus is rarely diagnosed in patients with solid tumors such as ovarian cancer. Risk factors for development of the disease can include neutropenia, immunosuppression and chronic steroid use. Successful treatment of the infection relies upon prompt diagnosis and utilization of effective antifungal medications for a prolonged period of time.
Although invasive aspergillosis is recognized as an increased concern for immunosuppressed patients, establishing an early diagnosis remains a challenge. Current methods for diagnosis, including sensitive radiography and invasive procedures to identify organisms in affected tissues, provide an early diagnosis for only a small proportion of patients infected with Aspergillus species. The availability of a standardized assay to detect circulating Aspergillus galactomannan, the BioRad Platelia Aspergillus galactomannan enzyme immunoassay, should be considered as a valuable tool. However, at present, clinical utility is hampered by controversies surrounding the performance of the test and an apparent lack of definitive data. These controversies emphasize the complexity inherent in analyzing diagnostic tests for aspergillosis. The widespread availability of a standardized assay may now allow us to address the multiple sources of variability and bias via large, cooperative studies.
