Aspergillosis comprises a variety of manifestations of infection. These guidelines are directed to 3 principal entities: invasive aspergillosis, involving several organ systems (particularly pulmonary disease); pulmonary aspergilloma; and allergic bronchopulmonary aspergillosis. The recommendations are distilled in this summary, but the reader is encouraged to review the more extensive discussions in subsequent sections, which show the strength of the recommendations and the quality of the evidence, and the original publications cited in detail. Invasive aspergillosis. Because it is highly lethal in the immunocompromised host, even in the face of therapy, work-up must be prompt and aggressive, and therapy may need to be initiated upon suspicion of the diagnosis, without definitive proof (BIII). Intravenous therapy should be used initially in rapidly progressing disease (BIII). The largest therapeutic experience is with amphotericin B deoxycholate, which should be given at maximum tolerated doses (e.g., 1-1.5 mg/kg/d) and should be continued, despite modest increases in serum creatinine levels (BIII). Lipid formulations of amphotericin are indicated for the patient who has impaired renal function or who develops nephrotoxicity while receiving deoxycholate amphotericin (AII). Oral itraconazole is an alternative for patients who can take oral medication, are likely to be adherent, can be demonstrated (by serum level monitoring) to absorb the drug, and lack the potential for interaction with other drugs (BII). Oral itraconazole is attractive for continuing therapy in the patient who responds to initial iv therapy (CIII). Therapy should be prolonged beyond resolution of disease and reversible underlying predispositions (BIII). Adjunctive therapy (particularly surgery and combination chemotherapy, also immunotherapy), may be useful in certain situations (CIII). Aspergilloma. The optimal treatment strategy for aspergilloma is unknown. Therapy is predominantly directed at preventing life-threatening hemoptysis. Surgical removal of aspergilloma is definitive treatment, but because of significant morbidity and mortality it should be reserved for high-risk patients such as those with episodes of life-threatening hemoptysis, and considered for patients with underlying sarcoidosis, immunocompromised patients, and those with increasing Aspergillus-specific IgG titers (CIII). Surgical candidates would need to have adequate pulmonary function to undergo the operation. Bronchial artery embolization rarely produces a permanent success, but may be useful as a temporizing procedure in patients with life-threatening hemoptysis. Endobronchial and intracavitary instillation of antifungals or oral itraconazole may be useful for this condition. Since the majority of aspergillomas do not cause life-threatening hemoptysis, the morbidity and cost of treatment must be weighed against the clinical benefit. Allergic bronchopulmonary aspergillosis (APBA). Although no well-designed studies have been carried out, the available data support the use of corticosteroids for acute exacerbations of ABPA (AII). Neither the optimal corticosteroid dose nor the duration of therapy has been standardized, but limited data suggest the starting dose should be approximately 0.5 mg/kg/d of prednisone. The decision to taper corticosteroids should be made on an individual basis, depending on the clinical course (BIII). The available data suggest that clinical symptoms alone are inadequate to make such decisions, since significant lung damage may occur in asymptomatic patients. Increasing serum IgE levels, new or worsening infiltrate on chest radiograph, and worsening spirometry suggest that corticosteroids should be used (BII). Multiple asthmatic exacerbations in a patient with ABPA suggest that chronic corticosteroid therapy should be used (BIII). Itraconazole appears useful as a corticosteroid sparing agent (BII).

Practice Guidelines for Diseases Caused by Aspergillus

A case-control study of patients with acute leukemia was done to identify significant risk factors for invasive pulmonary aspergillosis by reviewing the medical histories of 15 cases of pathologically proven invasive pulmonary aspergillosis and 45 controls. A history of lung or sinus disease, smoking, and multiple recurrences of leukemia did not increase the risk of invasive pulmonary aspergillosis. Cases and controls received similar chemotherapeutic regimens, and exposure to aminoglycosides, carbenicillin, trimethoprim-sulfamethoxazole, or corticosteroids was not significantly associated with development of invasive pulmonary aspergillosis. Among the factors tested, only granulocytopenia was associated with development of invasive pulmonary aspergillosis. Early in the course of granulocytopenia, patients developed signs of invasive pulmonary aspergillosis at a rate of approximately 1% per day. As the duration of granulocytopenia increased, the rate increased, approximating 4.3% per day between the 24th and 36th days. Of the 13 patients remaining granulocytopenic at 28 days, 7 had developed signs of invasive pulmonary aspergillosis. For patients with acute leukemia, granulocytopenia persisting longer than three weeks is the major risk factor for developing invasive pulmonary aspergillosis.

Prolonged granulocytopenia: the major risk factor for invasive pulmonary aspergillosis in patients with acute leukemia.

Purpose: To determine if in patients with single brain metastasis the addition of neurosurgery to radiotherapy leads to lengthening of survival or to better quality of life. Methods and Materials: From 1985 to 1990, 66 patients with single brain metastasis from a solid tumor were entered in a randomized trial of neurosurgery plus radiotherapy vs. radiotherapy alone. Patients were stratified for lung cancer vs. other sites of cancer and for progressive vs. stable systemic cancer. Radiotherapy was given to the whole brain by a novel scheme of two fractions of 2 Gy per day for a total dose of 40 Gy in 2 weeks, to obtain a relatively high total dose and short overall time, with minimal risk of late damage to normal tissue in long-term survivors. Results: In the whole group of 63 evaluable patients, both with lung cancer as with other tumors, the combined treatment led to a better duration of survival (median 10 vs. 6 months; p = 0.04). The largest difference between both treatment arms was observed in patients with inactive extracranial disease (median 12 vs. 7 months; p = 0.02). Patients with active extracranial disease had an equal median survival of only 5 months, irrespective of given treatment. Age proved to be a strong and independent prognostic factor: patients older than 60 years had a hazard ratio of dying of 2.74 (p = 0.003) compared with younger patients. Following treatment, most patients remained functionally independent until a few weeks before death. In the majority of patients the cause of death was systemic tumor progression. Conclusion: Patients with single brain metastasis and with controlled or absent extracranial tumor activity should be treated with surgery and radiotherapy, especially when they are younger than 60 years. For patients with progressive extracranial disease, radiotherapy alone seems to be sufficient. The accelerated radiotherapy scheme of 40 Gy in 2 weeks to the whole brain is tolerated well and should also be considered for patients in a good performance status with surgically unaccessible single metastasis or even with multiple brain metastases.

The choice of treatment of single brain metastasis should be based on extracranial tumor-activity and age

Aspergillus is a mould which may lead to a variety of infectious, allergic diseases depending on the host's immune status or pulmonary structure. Invasive pulmonary aspergillosis occurs primarily in patients with severe immunodeficiency. The significance of this infection has dramatically increased with growing numbers of patients with impaired immune state associated with the management of malignancy, organ transplantation, autoimmune and inflammatory conditions; critically ill patients and those with chronic obstructive pulmonary disease appear to be at an increased risk. The introduction of new noninvasive tests, combined with more effective and better-tolerated antifungal agents, has resulted in lower mortality rates associated with this infection. Chronic necrotising aspergillosis is a locally invasive disease described in patients with chronic lung disease or mild immunodeficiency. Aspergilloma is usually found in patients with previously formed cavities in the lung, whereas allergic bronchopulmonary aspergillosis, a hypersensitivity reaction to Aspergillus antigens, is generally seen in patients with atopy, asthma or cystic fibrosis. This review provides an update on the evolving epidemiology and risk factors of the major manifestations of Aspergillus lung disease and the clinical manifestations that should prompt the clinician to consider these conditions. Current approaches for the diagnosis and management of these syndromes are discussed.
