1/84. Aspergillus meningitis: diagnosis by non-culture-based microbiological methods and management.The performance of antibody detection, antigen detection, and Aspergillus genus-specific PCR for diagnosing Aspergillus meningitis was investigated with 26 cerebrospinal fluid (CSF) samples obtained from a single patient with proven infection caused by aspergillus fumigatus. immunoglobulin g antibodies directed against Aspergillus were not detected by enzyme-linked immunosorbent assay in CSF or serum. The antigen galactomannan was detected in the CSF 45 days before a culture became positive, and Aspergillus dna was detected 4 days prior to culture. Decline of the galactomannan antigen titer in the CSF during treatment with intravenous and intraventricular amphotericin b and intravenous voriconazole corresponded with the clinical response to treatment.- - - - - - - - - - ranking = 1keywords = sample (Clic here for more details about this article) |
2/84. Detection of PCR-amplified fungal dna by using a PCR-ELISA system.In order to speed up and standardize polymerase chain reaction (PCR)-based detection of medically important fungi in clinical samples we established a combination of commercially available kits for dna extraction, PCR amplification and detection of the amplicons. The PCR plate assay proved to be as sensitive and specific as our previously published assay (5 cfu ml(-1) blood). Moreover, in a selected group of patients, all patients with proven and probable invasive fungal infection were found to be PCR-positive. Thus the PCR plate assay was found to be a sensitive, technically simplified and standardized method with potential for adaptation to automation.- - - - - - - - - - ranking = 1keywords = sample (Clic here for more details about this article) |
3/84. CT appearance of a renal aspergilloma in a patient with the acquired immunodeficiency syndrome.The appearance of a unilateral renal aspergilloma on computed tomography is described in a 32-year-old man with acquired immunodeficiency syndrome (AIDS). Aspergillus infections are uncommon in the AIDS population. Only 9 cases of renal aspergilloma have been described in AIDS. The treatment performed was percutaneous drainage followed by antifungal drug administration and unilateral nephrectomy. This case report emphasizes the fact that renal fungal infections need to be considered in differential diagnosis of kidney infections in AIDS patients.- - - - - - - - - - ranking = 0.029186880775579keywords = size (Clic here for more details about this article) |
4/84. invasive pulmonary aspergillosis diagnosed early by polymerase chain reaction assay.We compared the usefulness of a polymerase chain reaction (PCR) assay for the early diagnosis of invasive pulmonary aspergillosis with the serodiagnosis of sufficient concentrations of galactomannan using the same serum samples. A patient was treated with prednisolone for the management of hepatitis. Computed tomography (CT) scan of the chest showed the nodular shadow with a cavity containing a clear fungus ball. dna of Aspergillus spp. from a serum sample was detected and using the same serum sample, both latex agglutination and sandwich enzyme-linked immunosorbent assay (ELISA) of galactomannan were negative. PCR assay provides an early diagnosis of invasive pulmonary aspergillosis compared with ELISA of galactomannan.- - - - - - - - - - ranking = 3keywords = sample (Clic here for more details about this article) |
5/84. magnetic resonance imaging and angiography in cerebral fungal vasculitis.We report on an 11-year old girl treated for leukemia who developed infarcts in the right lentiform nucleus and temporal lobe. magnetic resonance angiography (MRA) showed mild intraluminal irregularities in the right carotid syphon and stenosis of the right proximal middle cerebral artery, suggesting vasculitis. magnetic resonance imaging (MRI) follow-up showed evolution of the initial infarct into an abscess. Stereotactic biopsy disclosed filaments of aspergillus. This report emphasizes the fact that cerebral aspergillosis should be considered if MRA and MRI are indicative of vasculitis and cerebral infarction in immunosuppressed children.- - - - - - - - - - ranking = 0.029186880775579keywords = size (Clic here for more details about this article) |
6/84. Aspergillus osteoarthritis in acute lymphoblastic leukemia.We report an unusual case of arthritis of the right wrist due to aspergillus fumigatus without evidence for a generalized infection, following chemotherapy for acute lymphoblastic leukemia. The diagnosis was made by surgical biopsy. Amphotericin-B (Am-B) was not tolerated by the patient. Liposomal preparations of Am-B penetrate poorly into bone and cartilage. Therefore, oral itraconazole was given; the arthritis improved and chemotherapy was continued without infectious complications. Two weeks after complete hematopoietic recovery, an intracranial hemorrhage from a mycotic aneurysm of a brain vessel occurred, although the patient was still receiving itraconazole. We emphasize the importance of prompt and thorough efforts to identify the causative agent in immunocompromised patients with a joint infection. itraconazole is effective in Aspergillus osteoarthritis but, due to its poor penetration into the brain, the combination with a liposomal formulation of Am-B is recommended.- - - - - - - - - - ranking = 0.029186880775579keywords = size (Clic here for more details about this article) |
7/84. aspergillus fumigatus isolated from blood samples of a patient with pulmonary aspergilloma after embolization.Aspergillus dna was detected by PCR in the serum sample of a 78-year-old man and galactomannan antigen of Aspergillus by sandwich ELISA was found. However, the infiltrative hyphae were not detected by the histopathologic examination of the lung. He developed hemoptysis, which required embolization of bronchial arteries. aspergillus fumigatus was isolated from blood samples after embolization by the lysis centrifugation method. To our knowledge, this is probably the first case in which Aspergillus spp. has been isolated from the systemic circulatory blood in a patient with pulmonary aspergilloma after embolization.- - - - - - - - - - ranking = 6keywords = sample (Clic here for more details about this article) |
8/84. Aspergillus peritonitis in continuous ambulatory peritoneal dialysis patients.Aspergillus peritonitis is a rare and serious cause of peritonitis in continuous ambulatory peritoneal dialysis (CAPD) patients. We report 3 cases of aspergillus peritonitis in CAPD which were successfully treated by catheter removal and amphotericin. Two of the 3 patients returned temporarily to CAPD, but were subsequently transferred to hemodialysis because of membrane failure. A novel finding in 2 of the 3 cases was a positive Limulus amebocyte lysate test, despite negative bacterial cultures. We discuss the possible relevance of this finding to the diagnosis of aspergillus infections and emphasize the importance of early catheter removal for successful treatment of this condition.- - - - - - - - - - ranking = 0.029186880775579keywords = size (Clic here for more details about this article) |
9/84. Successful treatment of aspergillus brain abscess in a child with acute lymphoblastic leukemia.Cerebral aspergillosis carries a high mortality in immunocompromised patients. However, favorable outcome can be achieved by the prolonged use of antifungal agents and the maintenance of adequate drug levels. The authors report a 2-year-old girl who developed an aspergillus brain abscess during treatment for acute lymphoblastic leukemia. Predisposing factors for the fungal infection and details of the antifungal therapy are described. Prolonged treatment with AmBisome and 5-flucytosine successfully eradicated the lesion, but the girl's antileukemic therapy was compromised due to the infection. She developed a central nervous system and bone marrow relapse 9 and 15 months, respectively, after the initial presentation. The report emphasizes the need for further consideration of effective, long-term antifungal prophylaxis and a careful balance between aggressive treatment for severe infection and antileukemic therapy.- - - - - - - - - - ranking = 0.029186880775579keywords = size (Clic here for more details about this article) |
10/84. Disseminated aspergillosis in a renal transplant patient: Diagnostic difficulties re-emphasized.An asymptomatic and radiographically occult lung abscess was the primary focus of infection in this case of fatal disseminated aspergillosis in a renal transplant recipient. Extensive neurological evaluation in response to a change in personality failed to reveal a brain abscess, which was the cause of death. This case illustrates the variability in presentations of aspergillosis and the continuing difficulties in diagnosing this infection in immunosuppressed patients.- - - - - - - - - - ranking = 0.11674752310232keywords = size (Clic here for more details about this article) |
