To determine the value of aerosol amphotericin B inhalations for prevention of invasive pulmonary aspergillosis (IPA), we initiated a prospective randomized multicenter trial. The scheduled intent-to-treat interim analysis included 115 patients (30%) with prolonged neutropenia after chemotherapy for acute myeloid leukemia, acute lymphoblastic leukemia/high-grade non-Hodgkin's lymphoma, or solid tumors undergoing autologous stem cell transplantation. Sixty-five patients had been randomized to receive prophylactic aerosol amphotericin B inhalations at a dose of 10 mg twice daily (group A); for the remaining 50 patients no aerosol amphotericin B prophylaxis was used (group B). No serious side effects from amphotericin B inhalations occurred, but coughing (54%), bad taste (51%), and nausea (37%) caused early cessation of aerosol amphotericin B prophylaxis in 23% (15/65) of courses. In group A, the incidence of proven, probably, or possible IPA was 5% (3/65) as compared with 12% (6/50) in group B (p > 0.05). Microbiologically documented bacterial pneumonias were observed in 5/65 (8%) patients in group A and in 1/50 (2%) patients in group B (p > 0.05). Thus, no reduction in incidence of IPA from use of prophylactic aerosol amphotericin B inhalations was found in this interim analysis. As there were no serious side effects from aerosol amphotericin B prophylaxis, accrual in the study will continue for a total of 380 patients.

In patients with cystic fibrosis (CF), dehydration of airway secretions leads to a decrease in mucociliary clearance (MCC). We examined the acute effect of MCC of a single administration by aerosolization of hypertonic saline (7%) (HS), amiloride (0.3% in 0.12% NaCl) (AML) and a combination of AML and HS (AML + HS) in 12 patients with CF using a radioaerosol technique. Isotonic saline [0.9%] (IS) was used as a control solution. As both the AML and HS solutions induced cough in some patients, the last nine patients studied also underwent a cough clearance day. This was to eliminate the possible confounding effect of cough on MCC measurement. Patients ranged from 18 to 28 yr (mean +/- SD, 22 +/- 3) with an FEV1 of 27 to 112% predicted (61 +/- 30%). Following deposition of the radioaerosol, baseline clearance was assessed for 30 min. This was followed by a 30-min intervention period. Assessment of post-intervention clearance for a further 30 min was then performed. Comparison of the amount of radioaerosol cleared from the right lung was made at 60 min (%C60) and 90 min (%C90) using repeated measures ANOVA. The percent cleared at 60 and 90 min was significantly increased with HS (%C60 = 26.5%, %C90 = 29.4%) and the combination of AML + HS (%C60 = 23.1%, %C90 = 27.4%) compared with both IS (%C60 = 14.7%, %C90 = 17.5%) and COUGH (%C60 = 18.0%, %C90 = 19.5%), p < 0.01. Inhalation of hypertonic saline is a potentially useful treatment in patients with cystic fibrosis.

A cross-sectional study of quality of life (QOL) was performed in 98 patients in continued first complete remission (CR) for 1-7.4 years, after inclusion in the AML 8A trial which prospectively compared allogeneic bone marrow transplantation (AlloBMT), autologous BMT (ABMT) and intensive consolidation chemotherapy. Several significant differences between the three treatment groups were observed, on the basis of patient self-reports, with regard to somatic symptoms (mouth sores, cough, hair loss, headache), repeated acute medical problems, physical functioning, role functioning, leisure activities and, above all, sexual functioning. There were also significant differences for overall physical condition, and overall quality of life. For all these parameters, the ranking was uniformly AlloBMT lower than ABMT lower than chemotherapy. These differences remain significant after adjustment for time interval between CR and QOL evaluation, sex or age. These results, confirming a higher risk of permanent impairment of QOL after BMT, may have an impact on medical decisions and warrant further studies.

A retrospective study of 37 patients with haematological malignancy (21 acute myeloid leukaemia, 11 acute lymphoid leukaemia, two lymphoma, two hairy cell leukaemia, one Hodgkin's disease) and histologically documented mucormycosis was conducted to evaluate the clinical characteristics and ascertain the factors which influenced the outcome from mycotic infection. Patients were admitted to 18 haematology divisions in tertiary care or university hospitals in Italy between 1987 and 1995. Fever, thoracic pain, dyspnoea and cough were the most frequent presenting symptoms. At the onset, 89% patients were neutropenic (neutrophil counts < 0.5 x 10(9)/l) with a median duration of previous neutropenia of 14 d (range 6-60). The most frequent sites of infection were lungs (81%), CNS (27%), sinus (16%), liver (16%) and orbital space (10%). Only three patients were asymptomatic. A correct in vivo diagnosis was made in only 13 (35%) patients. When performed, thoracic and cranial CT scan were the most useful diagnostic investigations. Despite the fact that 26 febrile patients were treated with empirical antifungal treatment, 28 of the 37 patients (76%) died from fungal infection at a median time of 17 d from the onset of clinical symptoms. Nine patients were cured by antifungal therapy plus, in five cases, radical surgery procedures. An analysis of factors influencing outcome demonstrated that the resolution of chemotherapy-induced neutropenia and prolonged treatment with amphotericin B and, if feasible, radical surgical debridement treatment, were significantly correlated with recovery from infection. Mucormycosis, a rare filamentous fungal infection that occurs most frequently in neutropenic acute leukaemia patients, is characterized by a high mortality rate. Extensive and aggressive diagnostic and therapeutic procedures are essential to improve the prognosis in these patients.

A 42-year-old man was admitted with heavy retrosternal pain lasting 30 min. Electrocardiography showed typical signs of acute anterior myocardial infarction. The patient reported only attacks of coughing for a couple of days, and no serious diseases. The physical examination was normal. Laboratory tests showed a white blood cell count of 45/nl, platelet count of 58/nl, and hemoglobin of 14.4 g/dl. Blood chemistry showed elevated lactic dehydrogenase (413 U/l) but no elevation in creatine phosphokinase or glutamic-oxaloacetic transaminase. Therefore no thrombolysis was administered, but coronary angiography was performed. This showed a long-distance, subtotal thrombotic occlusion of the left anterior descending artery. After percutaneous transluminal coronary angioplasty and implantation of serial stents a normal perfusion of the artery was observed. The patient's blood and bone marrow films revealed acute myeloid leukemia FAB M2. Various conditions can cause a myocardial infarction in leukemias. We discuss the clinical management and the possible reasons for a subtotal thrombotic occlusion of the coronary artery.

46-year-old patient with acute myeloid leukemia (AML) whose disease manifested as fever, chills and dry cough is reported here. Despite broad antibiotic coverage he remained acutely ill with spiking fever, shaking chills, and hypoxemia. His initial chest radiograph was normal but chest computed tomography (CT) scan disclosed bilateral focal infiltrates. Hypoxemia and severe thrombocytopenia precluded invasive diagnostic procedures. A thorough epidemiological investigation revealed that before becoming acutely ill the patient smoked daily tobacco mixed with marijuana from a "hookah bottle". While waiting for tobacco and "hookah water" cultures, we started antifungal therapy. Resolution of fever and hypoxemia ensued after 72 hours. Tobacco cultures yielded heavy growth of Aspergillus species. We suggest that habitual smoking of Aspergillus-infested tobacco and marijuana caused airway colonization with Aspergillus. Leukemia rendered the patient immunocompromised, and allowed Aspergillus to infest the lung parenchyma with early occurrence of invasive pulmonary aspergillosis. Physicians should be aware of this potentially lethal complication of "hookah" and marijuana smoking in immunocompromised hosts.

A 53-year-old woman with refractory acute myeloid leukemia had a cough and chest pain. Chest X-ray and computed tomography demonstrated a cavity for which antibiotics, antituberculosis and antifungal agents were not effective. A diagnosis of pulmonary aspergillosis and pulmonary alveolar proteinosis (PAP) was made on the basis of the detection of aspergillus using transbronchial lung biopsy and PAS-positive materials in the sputum. Even though some cases with PAP in hematological malignancy have been reported, the diagnosis of PAP was obtained in most of them at autopsy. In our experience three of seven cases of hematological malignancy had concomitant occurrence of aspergillosis and PAP. We should therefore pay particular attention to the possibility of PAP in patients with hematological neoplasia exhibiting pulmonary fungal infection, especially aspergillosis.

In this case report, we present a pediatric case of lymphomatoid granulomatosis (LG) with onset just after the completion of chemotherapy for childhood acute myeloid leukemia (AML). After the completion of maintenance therapy, the patient was admitted to our clinic with a complaint of cough. Radiologic examinations revealed nodular lesions in lungs, liver, and kidney. His bone marrow was in remission. The histopathologic examination of the open lung biopsy was consistent with LG. He received only one cycle of cyclophosphamide and high-dose methyl prednisolone treatment and continued to receive interferon (IFN) alpha-2b therapy for 18 months. This treatment regimen resulted in an excellent response. In conclusion, LG may occur after the treatment of pediatric AML as a rare complication and IFN alpha-2b may be an effective treatment choice in these patients.

Reported here is a case of microsporidiasis that occurred in an acute myeloblastic leukemia (AML)-M3 patient who underwent chemotherapy. Fever, cough, expectorate and dyspnea were observed during the therapy. Since this case was considered as adult respiratory distress syndrome due to the chest X-ray and arterial blood gas findings, the male patient was bounded to a mechanical ventilator. As coagulation tests showed compatible findings with disseminate intravascular coagulation (DIC), it was thought to be a case of sepsis originating from the lungs and DIC. Pseudomonas aeruginosa and Staphylococcus aureus were found in the sputum of the patient. Although he was given combined antibiotic therapy, there was no reduction in the fever. A bronchoalveolar lavage (BAL) sample was taken and Microsporidia sp. was found upon staining with Giemsa. The patient died due to sepsis and DIC just before receiving therapy for microsporidiasis. Pulmonary infection with Microsporidia, although classically occurring in patients with HIV infection, may occur rarely in leukemia patients, especially if previously treated with systemic immune suppression. This case reinforces the need to consider Microsporidia as a possible pathogen in immunocompromised patients with pulmonary infections.

Granulocytic sarcoma is a soft tissue collection of leukemic cells. The authors describe a 4-year-old boy with M2 acute myelogenous leukemia (AML) who presented with fever, mild nonproductive cough, and hematemesis. Although he was initially diagnosed with nodular pneumonia, rapid resolution of a pulmonary infiltrate following induction chemotherapy was suggestive of a pulmonary granulocytic sarcoma. Interphase fluorescent in situ hybridization (FISH) of the lung biopsy specimen for the t(8;21)(q22;q22) translocation confirmed the retrospective diagnosis of a well-differentiated pulmonary granulocytic sarcoma. Pulmonary granulocytic sarcomas may be underrecognized in children with AML; this may delay anti-leukemic therapy and may lead to ineffective therapy if misdiagnosed as pneumonia.
