leukotriene b4 generation by human neutrophils following igg-dependent stimulation.it has previously been shown that human neutrophils generate substantial quantities of ltb4 when stimulated with the calcium ionophore, a23187, or with unopsonized zymosan. we now report that normal human neutrophils produced substantial quantities of ltb4 (measured by radioimmunoassay and validated by rp-hplc) when incubated with large non-phagocytosable igg-coated beads (sepharose 4b). ltb4 was identified in both the extra and intracellular compartments. the production of ltb4 was dependent up ...19872832306
[cytomegalovirus-associated superinfection of the lung following kidney transplantation].in a kidney-transplant patient, there was superinfection of the lungs by klebsiella pneumoniae and legionella pneumophilia with multiple necroses in the course of a primary cytomegalovirus infection. in a later phase of the disease, there was an opportunistic colonization of the necrotic cavities and the adjacent lung tissue by aspergillus fumigatus and candida albicans. the cytomegalovirus infection led to a pronounced cellular immunosuppression in the patient. this favored superinfections by b ...19873026768
degenerative changes in fungi after itraconazole treatment.changes in morphogenetic behavior and structural degeneration after exposure to itraconazole are illustrated in candida albicans, cryptococcus neoformans, pityrosporum ovale, paracoccidioides brasiliensis, trichophyton rubrum, and aspergillus fumigatus. with the exception of p. ovale, primary alterations are seen at the cell periphery and the cytoplasmic vacuoles in which lipid-like vesicles assemble. these changes are usually accompanied by a marked increase in cell volume, impaired cell divisi ...19873027844
early experience with itraconazole in vitro and in patients: pharmacokinetic studies and clinical results.the efficacy of itraconazole, a new triazole antifungal agent, was studied in vitro and assessed in patients. the mics of itraconazole for 16 strains of aspergillus fumigatus were in the same range as those of amphotericin b: less than 0.09-0.36 microgram/ml vs. less than 0.09-0.78 microgram/ml, respectively. eight adult patients with systemic fungal infections were treated orally with 100-200 mg of itraconazole two times a day. a patient with relapsing histoplasmosis (histoplasma capsulatum var ...19873027850
[aspergillosis following liver transplantation as a hospital infection].in the first four weeks after a liver transplantation, there was an invasive aspergillosis with a lethal course in three out of five patients who were treated postoperatively in the same room. the clinical symptoms were very different. one patient was asymptomatic, and the diagnosis could only be made by autopsy. in another patient, pulmonary symptoms, and in the third patient, cerebral symptoms were the most prominent. in the two latter patients, the infection was demonstrated in the sputum and ...19873028750
efficacy of fluconazole (uk-49,858) against experimental aspergillosis and cryptococcosis in mice.the efficacy of fluconazole, a new bis-triazole antifungal agent, was compared with that of orally administered ketoconazole and parenterally administered amphotericin b against aspergillus and cryptococcus infections in mice. fluconazole was 5-20-fold more active than ketoconazole against systemic aspergillosis and against systemic, intracranial and pulmonary cryptococcosis but was less active than amphotericin b.19873038824
suppression of host defences by aspergillus fumigatus.an important feature of the microbicidal action of phagocytic cells is their ability to produce reactive oxygen intermediates. in an attempt to identify the mechanisms by which the fungus aspergillus fumigatus resists normal host defences the effect of spores and spore diffusates of a fumigatus on the production of superoxide anion and hydrogen peroxide by primed rodent phagocytic cells has been measured. for comparison we have used the non-pathogenic fungus penicillium ochrochloron. production ...19873039682
oxidative killing of aspergillus fumigatus proceeds by parallel myeloperoxidase-dependent and -independent pathways.the relative importance of several oxygen intermediates in fungicidal action against opsonized aspergillus fumigatus conidia was investigated with monocytes from normal volunteers and patients with either chronic granulomatous disease or myeloperoxidase (mpo) deficiency. results from experiments in which catalase, taurine, mannitol, or glucose-glucose oxidase were added to these phagocytes indicated that the mpo-hydrogen peroxide-halide system and an mpo-independent oxidative system exerted comp ...19873040589
activation of human serum complement with allergens. i. generation of c3a, c4a, and c5a and induction of human neutrophil aggregation.to understand the relevance of allergens in generation of c3a, c4a, and c5a in normal human serum, we studied extracts of several allergens (house dust, house dust mite, aspergillus fumigatus, and perennial ryegrass). known complement activators zymosan and endotoxin were used as controls. generation of c3a, c4a, and c5a (determined by radioimmunoassays) occurred with extracts of house dust and aspergillus more than with house dust mite and ryegrass. anaphylatoxins were produced both in dose and ...19873496373

invasive pulmonary aspergillosis: radiologic evidence of tracheal involvement.chest radiographs of invasive pulmonary aspergillosis in immunocompromised patients typically show ill-defined pulmonary nodules. direct tracheal involvement has not been previously documented radiologically. radiographs and ct scans of a 16-year-old boy with aplastic anemia and invasive pulmonary aspergillosis showed increased paratracheal opacity, tracheal narrowing, and pneumomediastinum in combination with pulmonary disease. bronchial lavage cultures grew aspergillus fumigatus, and the boy d ...19873317503
chip pile workers and mould exposure. a preliminary clinical and hygienic survey.chip pile workers are exposed to high concentrations of airborne mould spores. few sporadic cases of allergic alveolitis have been reported in finland. eight non-smoking workers, six on chip piles and two on bark piles, were examined to study the immunological and clinical response to continuous mould spore exposure. the spore exposure ranged between 10(4) and 10(5) spores/m3. three of the six chip pile workers had precipitating serum antibodies against aspergillus fumigatus. the three antibody- ...19873318540
characterization of a second major antigen ag 13 (antigen c) of aspergillus fumigatus and investigation of its immunological reactivity.a second major antigen of aspergillus fumigatus (ag 13) has been identified and characterized as a 70 kd, heat-labile component which is able to bind to the lectin, concanavalin a. ag 13 proved to be identical to the previously recognized c antigen, known to possess chymotryptic activity. a monospecific antiserum to ag 13 has been affinity purified and used to develop a sandwich elisa for measuring levels of ag 13 specific igg antibodies in patients' sera. although all abpa sera (25/25) had sign ...19873319301
invasive pulmonary aspergillosis: a diagnostic and therapeutic problem. clinical experience with eight haematologic patients.eight patients with haematologic malignancies contracted fatal invasive aspergillosis during an outbreak. five patients were neutropenic. bronchofiberoscopic examination with microbiology specimen brush and bronchoalveolar lavage yielded aspergillus fumigatus in only 2/5 patients examined. the specific diagnosis reached during lifetime in 5 patients was based on a combination of invasive procedures (lung biopsy in 2, percutaneous lung puncture in 1), the presence of a lung abscess (3 patients), ...19873321414
pathogenetic and serological aspects of pulmonary aspergillosis.af is an important pathogen of the bronchopulmonary system, and the clinical spectrum encompasses aspergilloma, cnpa, ipa, abpa, bronchial asthma, and allergic alveolitis. bronchial carriage may, however, not always be associated with pathological effects. the polymorphism of the aspergillus-related disorders seems mostly to depend upon the different responses of the hosts. this review considers the antigenic composition of af and specific antibody responses in man in relation to the pathogenesi ...19873321416

evaluation of a test to detect circulating aspergillus fumigatus antigen in a survey of immunocompromised patients with proven or suspected invasive disease.an elisa for the detection and measurement of aspergillus antigenaemia has been developed and evaluated by examining sera submitted over a 12-month period from immunocompromised patients with a likelihood of invasive aspergillosis. results from proven cases of invasive aspergillosis confirmed at post-mortem and specimens from individuals with suspected disease showed that tests on single serum samples were often negative. multiple specimens from the same patient greatly increased the frequency o ...19873325629
inhibition of phagocyte migration and spreading by spore diffusates of aspergillus fumigatus.previous studies have shown that spores of aspergillus fumigatus inhibit phagocytosis and killing by macrophages and polymorphonuclear leucocytes. in order to identify the mechanisms of this interference with host defences, we have examined the effects of a. fumigatus spore diffusates on phagocytic cell function. for comparison, we have used spore diffusates of the non-pathogenic fungus penicillium ochrochloron. the diffusates of a. fumigatus reduced the number of human polymorphonuclear leukocy ...19873325630
