A pilot exploratory study was undertaken to collect preliminary information relating to safety and overall outcome in using intravenous fluconazole (FLUC) for managing antibiotic resistant neutropenic fever (ARNF), with the objective of assessing feasibility of performing a larger prospective controlled study. Patients who were neutropenic from treatment for leukaemia or bone marrow transplantation, received either fluconazole (FLUC) or amphotericin B (AB). Eight of 16 patients (50%) on FLUC and 21 of 25 patients (84%) on AB defervesced; the mean time to defervescence was 11.0 +/- 10.0 days for FLUC compared to 7.7 +/- 6.3 days for AB, and a similar proportion in each treatment group defervesced within 5 days (50% vs. 52%), respectively. Six of 16 patients (37.5%) on FLUC and three of 25 patients (12%) on AB developed overt invasive fungal disease, including pulmonary aspergillosis (FLUC 4 cases, AB 2 cases) and invasive candidiasis (FLUC 2 cases, AB 0 cases). The mean time to these events was 19.5 +/- 13.4 (FLUC) and 9.0 +/- 3.6 (AB) days. The fungal related mortality rates were higher in the FLUC group: five of 16 patients (31%) vs. two of 25 patients (18%) died respectively; the time to fungal death was 43.2 +/- 18.2 (FLUC) and 25.0 +/- 18.4 (AB) days. This tendency towards a more favourable outcome in patients on AB may have been due to absence of prior fluconazole prophylaxis in patients subsequently receiving IV FLUC. Analysis of a small subgroup of patients who had all received prior prophylaxis with clotrimazole only, indicated that a greater number of patients subsequently receiving IV FLUC died from fungal disease (5/16 vs.0/6, P = 0.09).(ABSTRACT TRUNCATED AT 250 WORDS)

Candida krusei is a cause of invasive candidiasis (IC), with numerous cases reported among leukemia patients after bone marrow transplantation and treatment with fluconazole. The relation between fluconazole therapy and IC remains controversial. In a retrospective review covering 5 years, we identified 203 cases of IC, 71 (35%) of which were due to non-albicans species. Eight cases were caused by C. krusei: four of the patients involved had leukemia, two had breast cancer, one had end-stage liver disease, and one had undergone abdominal trauma. None of these patients received fluconazole. Surveillance cultures detected colonization with C. krusei before the onset of symptoms in seven cases. The median time from colonization to IC diagnosis was 10 days. Of six patients with neutropenia, five were neutropenic at IC diagnosis. Concomitant infections were common; four patients had both bacteremia and invasive aspergillosis. C. krusei was considered the immediate cause of five of the seven deaths among this group of patients. These eight cases extend the range of immunocompromised conditions in which IC caused by C. krusei develops in the absence of fluconazole therapy.

A 5-year-old girl developed cutaneous aspergillosis due to Aspergillus flavus while undergoing remission induction therapy for acute lymphocytic leukemia. Of six serum samples obtained during the acute stage of Aspergillus infection, four showed antigenemia (6.5-22.9 ng/ml) determined by enzyme-linked immunosorbent assay (ELISA). However, five serum samples obtained after treatment with amphotericin B and granulocyte-colony stimulating factor showed negative results for antigens. Sera obtained on day 17 after the detection of skin lesions showed seroconversion in precipitin antibody determined by an immunodiffusion test and in immunoglobulin (Ig) A class antibody determined by ELISA, while sera obtained on day 24 showed seroconversion of IgG and IgM class antibodies. The patient achieved complete remission of leukemia and was discharged on the 92nd day of hospitalization. No signs of disseminated or deep-seated fungal infections were present during the hospitalization. Assays for serum antigens may be of value for the early diagnosis of invasive aspergillosis. Moreover, persistently negative results for antigens in accordance with antibody responses may correlate with recovery from the infection.

Cerebral aspergillosis has a very poor prognosis. When this complication occurs in the immunocompromised host, evolution is virtually fatal in all cases despite surgical and medical treatment. We describe in this report the case of a child with acute lymphoblastic leukaemia who developed pulmonary aspergillosis, and subsequent cerebral dissemination during therapeutic induction. Due to multifocal cerebral lesions, surgery was impossible. The patient was administered long term treatment including amphotericin B, flucytosine and itraconazole for 9 months, during which time a neutropenic period occurred with reactivation of cerebral mycotic lesions, in spite of modification of antileukaemic therapy. Seven years later, he nevertheless remains in complete remission without any neurological sequelae. Thus cerebral aspergillosis requires early diagnosis and can be treated using a strong combination of antimycotic drugs (amphotericin B, flucytosine and itraconazole) on a long term basis, even when aspergillomas cannot be removed surgically. Antileukaemic therapy must be concomitantly adapted to avoid or limit neutropenia.

Encephalopathy, leukoencephalopathy, and secondary parkinsonism occurred in 3 children with refractory leukemia undergoing allogenic bone marrow transplantation (BMT) who were treated with high-dose amphotericin B for pulmonary aspergillosis or sinus aspergillosis that did not involve the nervous system. Treatment included high-dose cytosine arabinoside, cyclophosphamide, and total body irradiation prior to the BMT. The children developed a progressively worsening encephalopathy and parkinsonian features, characterized by resting tremor, cogwheel rigidity, and masklike facies. Neuroimaging studies showed cerebellar, cerebral, and basal ganglia atrophy, as well as frontal and temporal lobe white matter involvement. Two of the 3 patients recovered, although 1 has residual intellectual impairment. The third succumbed to non-central nervous system Epstein-Barr virus-lymphoproliferative disease and had autopsy-confirmed leukoenephalopathy.

Invasive pulmonary aspergillosis generally occurs in immunocompromised hosts such as patients with leukemia, and other malignancies, who are receiving anti-cancer chemotherapy. In this report, two non-immunocompromised patients who developed invasive pulmonary aspergillosis are presented. Case 1: A 63-year-old man complained of productive cough and fever. He received antibiotic therapy from his personal physician. This symptoms did not respond, however, and dyspnea developed. He was then transferred to our hospital, about one month after the onset. The chest X-ray showed a meniscus shadow suggesting an aspergilloma in the right upper lung field and an infiltrative shadow in the remaining right lung field. Case 2: A 78-year-old man was admitted because of dyspnea, productive cough and appetite loss over the previous three months. The chest X-ray showed a meniscus shadow in the left upper field, an infiltrative shadow in the left lower field and a right pleural effusion sign was also observed. Both cases were diagnosed as having aspergillosis, early in their illness, by the detection of aspergillus antigen in their sera and histopathological and cultural studies of specimens obtained by TBLB. Both improved with intravenous amphotericin B (30 mg/day) and intravenous ulinastatin (200000 IU/day) administration. On the examinations conducted during hospitalization, there was no evidence of any immunosuppressive diseases or immunoincompetent conditions such as leukemia, and other malignancies human immunodeficiency virus infection, diabetes or alcoholism.

Pituitary metastases constitute 1% to 8.3% of all metastatic brain tumors. The most frequent localization is in the posterior lobe and diabetes insipidus may be the only symptom of dysfunction. Cerebral aspergillosis is an unusual disease and it has been described complicating an underlying malignancy or following intracraneal surgery. We describe a case of hypopituitarism and hyperprolactinemia in a patient with pituitary metastases of a colon carcinoma and aspergillosis. Two years before a colon adenocarcinoma (Class C1 of Duke) had been resected. There were no clinical signs of hypopituitarism or galactorrea. The laboratory findings showed deficiency of cortocotropin (ACTH), luteinizing hormone (LH), follicle stimulating hormone (FSH) and slight hyperprolactinemia (PRL). Cerebral magnetic resonance image (MRI) revealed an intra and suprasellar mass which extended to the hypothalamus. Chest X-ray film and computed tomographic scanning (TC) confirmed a macronodular mass at the apical segment of the inferior left lung lobule with mediastinal hypertrophic lymph nodes. A non functional pituitary tumor was diagnosed and transphenoidal surgery was carried out. At microscopic examination a malignant proliferation was found suggesting colonic differentiation. Fragments of tumoral pituitary tissue showed hyphae of aspergillus in the form of abscess. Aspergillosis complicating neoplastic disease is more often present in leukemia and lymphoma than in solid tumors.(ABSTRACT TRUNCATED AT 250 WORDS)

Three children who developed pulmonary aspergillosis while being treated for leukaemia or non-Hodgkin's lymphoma. Each child continued with intensive myelosuppressive chemotherapy regimens during the infection and each was successfully treated with antifungal prophylaxis based on itraconazole by mouth. Amphotericin B was also given during periods of severe neutropenia. No reactivation of the fungal infection was seen.

The clinicopathologic characteristics of invasive oral aspergillosis in 16 immunocompromised patients who developed this infection during antileukemic chemotherapy are described. The primary site of the infection was the marginal gingiva, there was severe spontaneous pain, and the patients developed spiking fever and granulocytopenia. Necrotic ulceration of the gingiva rapidly extended to the contiguous mucosa, muscle, and bone. Microscopically, the necrotic tissue contained thrombotic vascular infarcts and there were hyphae that showed frequent transverse septa and dichotomous branching. The invasive organisms were not responsive to amphotericin B in the absence of remission of the leukemia and restoration of the depressed host defenses. In 15 patients who showed improvement of hematologic status, oral aspergillosis was controlled by the combination of antifungal chemotherapy and debridement of necrotic tissues.

A case of invasive broncopulmonar aspergillosis caused by Aspergillus terreus successfully treated with itraconazole is reported in a patient undergoing autologous bone marrow transplantation for acute lymphoblastic leukaemia. Although the patient was on prophylaxis with fluconazole and she did not respond to amphotericin B, there was an excellent response to itraconazole which allowed the transplant without any Aspergillus infection during both the transplant and the post-transplant periods. Due to its oral administration, good tolerance and low toxicity, itraconazole is a promising drug for the treatment of invasive broncopulmonar aspergillosis.
