Abstract
BACKGROUND/AIM Invasive aspergillosis (IA) is a fatal infection that is difficult to diagnose in immunocompromised patients. In this study, Aspergillus-specific DNA was searched using real-time PCR (RT-PCR) in serum samples. Galactomannan (GM) and/or beta-D-glucan (BDG) tests were previously performed on these samples for 70 neutropenic patients with hematological malignancy. MATERIALS AND METHODS The patients were categorized according to the criteria of the European Organization for Research and Treatment of Cancer/Mycoses Study Group (EORTC/MSG). Among the patient serum samples, the first positive GM or BDG test sample and the median sample of GM or BDG test for negative patients were used to detect DNA levels by RT-PCR method (Light Cycler 480, Roche Molecular Biochemicals, Meylan, France) using a commercial kit (Way2Gene Fungi; Genmar, İzmir, Turkey). RESULTS When the proven and probable IA group were considered as real patients, sensitivity of Aspergillus-specific DNA test was 90%, specificity was 73.3%, positive predictive value was 81.8%, and negative predictive value was 84.6%. CONCLUSION This study found that searching for specific DNA by RT-PCR method has a sensitivity as high as the GM test. Although specificity was rather low, it was concluded that it can be used jointly with GM and BDG tests after decreasing contamination by severe laboratory applications.

Abstract
In this paper we analysed clinical, laboratory characteristics and outcome of patients with haematological diseases who developed an Aspergillus niger infection, in a multicentre study involving 14 Italian Haematological Divisions during a 10-year period. The study recorded 194 consecutive microbiologically documented aspergilloses, eight of which (4%) were due to A. niger, and were observed only in five of the participating centres. The primary localization of infection was lung in seven cases and paranasal sinus in one case. Seven patients died at the end of follow-up. The death was mainly attributable to A. niger progression in six of them. Our study that collected the largest number of cases of A. niger infection in haematological malignancies confirms that this infrequent complication is characterized by a high mortality rate.

Abstract
The term "aspergillosis" comprises several categories of infection: invasive aspergillosis; chronic necrotizing aspergillosis; aspergilloma, or fungus ball; and allergic bronchopulmonary aspergillosis. In 24 medical centers, we examined the impact of a culture positive for Aspergillus species on the diagnosis, risk factors, management, and outcome associated with these diseases. Most Aspergillus culture isolates from nonsterile body sites do not represent disease. However, for high-risk patients, such as allogeneic bone marrow transplant recipients (60%), persons with hematologic cancer (50%), and those with signs of neutropenia (60%) or malnutrition (30%), a positive culture result is associated with invasive disease. When such risk factors as human immunodeficiency virus infection (20%), solid-organ transplantation (20%), corticosteroid use (20%), or an underlying pulmonary disease (10%) are associated with a positive culture result, clinical judgment and better diagnostic tests are necessary. The management of invasive aspergillosis remains suboptimal: only 38% of patients are alive 3 months after diagnosis. Chronic necrotizing aspergillosis, aspergilloma, and allergic bronchopulmonary aspergillosis have variable management strategies and better short-term outcomes.

Abstract
We describe two patients with acute leukaemia who died of massive haemoptysis caused by invasive pulmonary aspergillosis (IPA). The fatal event occurred during the period of bone marrow remission which followed chemotherapy-induced neutropenia. This is a rare complication. We were able to find additional 17 similar cases in the English literature, which we review. Clinically, the picture consisted of unremitting fever with profound and prolonged neutropenia, cough and dyspnoea. Both our patients were treated with broad-spectrum antibiotics, fluconazole and amphotericin B. An upper lobe infiltrate in one case, and a progressive pleural effusion in the other, were late findings on chest radiographs during the period of bone marrow recovery. Both patients succumbed to sudden massive haemoptysis during the period of bone marrow and clinical improvement. In conclusion, patients with acute non-lymphoid leukaemia are at significant risk for IPA-induced fatal haemoptysis during bone marrow and clinical remission. A high index of suspicion should be sustained throughout the entire clinical course. In view of the potential fatal outcome, aggressive diagnostic and treatment efforts are mandatory.

Abstract
PURPOSE To define the role of lower-respiratory-tract cultures in the diagnosis of invasive pulmonary aspergillosis (IPA) in immunocompromised hosts. METHODS Immunocompromised patients with a positive, nonbiopsy, lower-respiratory-tract culture for Aspergillus species were classified as having definite, probable, indeterminate, or no IPA. Culture data, positive predictive values (PPVs), correlation with clinical and radiographic findings, and the relationship between the number of specimens submitted and the likelihood of recovering Aspergillus were assessed. RESULTS Definite or probable IPA was diagnosed in 72% of episodes from patients with hematologic malignancy, granulocytopenia, or bone-marrow transplant; in 58% of those with solid-organ transplant or using corticosteroids; and in 14% of those with human immunodeficiency virus infection. The PPV of cultures ranged from 14% in the latter group to 72% in the first group (bone-marrow-transplantation subgroup, 82%). Fungal cultures were more often positive than were routine cultures (P < 0.001). Clinical and radiographic findings suggestive of IPA were present more frequently in infected than uninfected patients (59% versus 24%, P < 0.025); and 73% versus 6%, (P < 0.0001, respectively). Infected patients with > or = 1 positive node had more cultures submitted than a control group of patients with no positive cultures (5.8 +/- 4.7 versus 2.1 +/- 2.2 cultures, P < 0.001). CONCLUSION Recovery of Aspergillus species from high-risk patients is associated with invasive infection. Clinical and radiographic correlations help to separate true- from false-positive cultures. At least 3 sputum specimens should be submitted for fungal culture whenever fungal infection is suspected.

Abstract
A retrospective study on a consecutive series of 116 patients affected by acute leukaemia with documented pulmonary filamentous mycosis (FM) admitted between 1987 and 1992 to 14 tertiary-care hospitals in Italy was made in order to evaluate the characteristics of those patients who developed fatal massive haemoptysis. In 59/116 cases of pulmonary FM the infection was the principal cause of death and in 12 of these patients a massive haemoptysis was responsible for death. The diagnosis of FM infection was made ante-mortem in only four out of these 12 patients. The autopsy was performed in 11/12 patients and documented a FM infection. The mycetes isolated were: Hyphomycetes spp. (three patients), Mucorales spp. (two patients), Aspergillus spp. (seven patients). At the time of the massive haemoptysis the mean neutrophil count was 7.2 x 10(9)/l, and no patient had relevant thrombocytopenia (mean 184 x 10(9)/l, range 28-350) or coagulative abnormalities. The mean time which elapsed between resolution of chemotherapy-induced neutropenia (WBC < 10(9)/l) and occurrence of haemoptysis was 7 d. No signs or symptoms predictive of this fatal complication were identified. Massive haemoptysis can be the cause of death in patients with acute leukaemia and pulmonary FM which in the majority of patients was not diagnosed in vivo. This complication occurs most frequently shortly after the recovery from chemotherapy-induced aplasia. The mechanism of lesion is unknown, but it may involve the vascular tropism of FM and the release of leucocyte enzymes. Better preventive and therapeutic antifungal treatments are needed to avoid this serious, albeit rare, complication.

Abstract
BACKGROUND Different empirical approaches to antimicrobial treatment of lung infiltrates in patients with neutropenia were studied within a prospective, randomized multicenter trial. METHODS Patients with neutropenia with hematologic malignancies and fever of 38.5 degrees C or higher associated with newly diagnosed lung infiltrates were randomized for an initial therapy with acylaminopenicillin plus aminoglycoside (Group A), third-generation cephalosporin plus aminoglycoside (Group B), or the double beta-lactam combination (Group C), each in combination with rifampin. Nonresponders were given empirical amphotericin B plus 5-fluorocytosine beginning on day 4, day 5, or day 6 under study. RESULTS Of 295 patients entered, 91.2% were evaluable. Complete response was obtained in 61.3% with no significant difference between treatment groups. The addition of rifampin did not improve treatment results. Only 27.1% of patients achieved a complete response by antibiotic therapy without additional antifungal therapy. Fungi dominated in cases of microbiologically documented infections and were associated with a poorer outcome compared with bacterial pneumonias. The trend of leukocyte counts under study had a highly significant effect on the outcome of infection. CONCLUSIONS Lung infiltrates in febrile patients with neutropenia represent a high risk of treatment failure. Persistent neutropenia has a significantly adverse effect on the outcome of infection. Incorporation of systemic antifungal agents into first-line therapy, particularly in selected high-risk subgroups, might improve future treatment results. The quality of diagnostic techniques to establish the etiology of pulmonary infiltrates needs to be improved.

Abstract
OBJECTIVES To determine the prevalence of aspergillosis in lymphoma patients housed in a protective environment while undergoing a bone marrow transplant or peripheral stem cell transplant and its relation to lymphoma type, type of transplant, period of neutropenia, method of diagnosis, species of Aspergillus, and the use of empiric amphotericin B. DESIGN Clinical, autopsy, and microbiology records were reviewed retrospectively to determine the presence or absence of invasive aspergillosis. All positive specimens underwent further review to determine parameters outlined above. SETTING The review took place at the University of Nebraska Medical Center with lymphoma patients housed in the oncology/hematology special care unit, which consists of 30 single-patient rooms under positive pressure with high-efficiency particulate air filtration. PATIENTS 417 lymphoma patients admitted to the oncology/hematology special care unit who underwent 427 courses of high-dose chemotherapy with or without total body irradiation followed by a stem cell rescue. RESULTS Twenty-two cases (5.2%) of nosocomial invasive aspergillosis (14 caused by Aspergillus flavus, 2 by Aspergillus terreus, 2 by Aspergillus fumigatus, and 4 by characteristic histology) were diagnosed. The prevalence of disease according to transplant was 8.7% for allogeneic bone marrow transplant (2/23 treatments), 5.6% for autologous peripheral stem cell transplant (9/161), and 4.5% for autologous bone marrow transplant (11/243). Fifteen patients were presumptively diagnosed prior to death (68.2%) most commonly by histologic examination of skin biopsies. All 22 patients received amphotericin B therapy, 17 prior to aspergillosis diagnosis, and 7 (31.8%) survived. No patient with disseminated disease survived. CONCLUSIONS Even when housing lymphoma patients undergoing myeloablative therapy in a protective environment containing high-efficiency particulate air filtration, there was a risk of developing aspergillosis. These data also showed that antemortem diagnosis with aggressive amphotericin B therapy was most effective in the management of infected lymphoma patients when engraftment occurred and the disease did not become disseminated.
