Abstract
A 65-year-old woman presented to a local hospital with a 4-day history of cough, fever, and dyspnea. She had started using a composter and had been exposed to the vapor for 18 days before her first visit. She was diagnosed with acute eosinophilic pneumonia (AEP) based on her symptoms, the presence of bilateral pulmonary opacities on computed tomography, and alveolar eosinophilia confirmed by bronchoalveolar lavage. Inhalation of the composter vapor was thought to be the cause of AEP. Aspergillus fumigatus was cultured from the composter soil and the bronchoalveolar lavage fluid. She fully recovered without systemic corticosteroid administration by avoiding the composter.

Invasive pulmonary mucormycosis: rare presentation with pulmonary eosinophilia. BMC Pulm Med 2017; 17:76.

Abstract
BACKGROUND Fungi can cause a variety of infectious diseases, including invasive mycosis and non-invasive mycosis, as well as allergic diseases. The different forms of mycosis usually have been described as mutually exclusive, independent entities, with few descriptions of overlapping cases. Here, we describe the first reported case of a patient with the complication of pulmonary eosinophilia in the course of invasive mucormycosis. CASE PRESENTATION A 74-year-old Japanese man with asthma-COPD overlap underwent emergency surgery for a ruptured abdominal aortic aneurysm. The surgery was successful, but fever and worsening dyspnea appeared and continued from postoperative day (POD) 10. A complete blood count showed leukocytosis with neutrophilia and eosinophilia, and the chest X-ray showed consolidation of the left upper lung at POD 15. We suspected nosocomial pneumonia together with an exacerbation of the asthma-COPD overlap, and both antibiotics and bronchodilator therapy were initiated. However, the symptoms, eosinophilia and imaging findings deteriorated. We then performed a bronchoscopy, and bronchoalveolar lavage (BAL) fluid analysis revealed an increased percentage of eosinophils (82% of whole cells) as well as filamentous fungi. We first suspected that this was a case of allergic bronchopulmonary mycosis (ABPM) caused by Aspergillus infection and began corticosteroid therapy with an intravenous administration of voriconazole at POD 27. However, the fungal culture examination of the BAL fluid revealed mucormycetes, which were later identified as Cunninghamella bertholletiae by PCR and DNA sequencing. We then switched the antifungal agent to liposomal amphotericin B for the treatment of the pulmonary mucormycosis at POD 29. Despite replacing voriconazole with liposomal amphotericin B, the patient developed septic shock and died at POD 39. The autopsy revealed that filamentous fungi had invaded the lung, heart, thyroid glands, kidneys, and spleen, suggesting that disseminated mucormycosis had occurred. CONCLUSIONS We describe the first reported case of pulmonary mucormycosis with pulmonary eosinophilia caused by Cunninghamella bertholletiae, which resulted in disseminated mucormycosis. Although it is a rather rare case, two important conclusions can be drawn: i) mycosis can simultaneously cause both invasive infection and a host allergic reaction, and ii) Cunninghamella bertholletiae rarely infects immunocompetent patients.

Abstract
Eosinophilic lung diseases especially comprise eosinophilic pneumonia or as the more transient Löffler syndrome, which is most often due to parasitic infections. The diagnosis of eosinophilic pneumonia is based on characteristic clinical-imaging features and the demonstration of alveolar eosinophilia, defined as at least 25% eosinophils at BAL. Peripheral blood eosinophilia is common but may be absent at presentation in idiopathic acute eosinophilic pneumonia, which may be misdiagnosed as severe infectious pneumonia. All possible causes of eosinophilia, including drug, toxin, fungus related etiologies, must be thoroughly investigated. Extrathoracic manifestations should raise the suspicion of eosinophilic granulomatosis with polyangiitis.

Abstract
We report a case of acute respiratory failure in a 77-year-old male with chronic obstructive pulmonary disease (COPD) who showed marked eosinophilia (61.5% of the peripheral total white blood cells [WBCs]; 13,200/mm(3)). The patient was an ex-smoker, but he had started smoking again one month previously, His forced expiratory volume in one second (FEV1) was low and dyspnea symptom was observed. Although rhonchi were detected, wheezing chest sounds were not detected. Chest X-radiography and computed tomography of the lung revealed diffuse bilateral pulmonary infiltrates and emphysematous changes. He was given intravenous methyl prednisolone (1,000 mg) for 3 consecutive days. The abnormal shadows on the chest X-ray film improved remarkably and the eosinophils in his peripheral blood were reduced. Furthermore, it was no longer necessary to administer oxygen to treat his hypoxemia. The symptomatic and clinical course mimicked to a case of acute eosinophilic pneumonia (AEP). However, transbronchial lung biopsy specimens did not reveal eosinophilic infiltration in the alveolar septa. The fraction of eosinophils in the patient's bronchoalveolar lavage was 4.4% and not greater than 25%. After hospitalization, 5-15 mg of prednisolone administered orally in combination with bronchodilators to better manage his clinical symptoms. This case was thus determined to correspond to elderly asthma-COPD overlap syndrome (ACOS).

Abstract
Acute eosinophilic pneumonia is a severe and rapidly progressive lung disease that can cause fatal respiratory failure. Since this disease exhibits totally different clinical features to other eosinophilic lung diseases (ELD), it is not difficult to distinguish it among other ELDs. However, this can be similar to other diseases causing acute respiratory distress syndrome or severe community-acquired pneumonia, so the diagnosis can be delayed. The cause of this disease in the majority of patients is unknown, even though some cases may be caused by smoke, other patients inhaled dust or drugs. The diagnosis is established by bronchoalveolar lavage. Treatment with corticosteroids shows a rapid and dramatic positive response without recurrence.

Abstract
INTRODUCTION Atypical mycobacteria and Aspergillus are opportunistic organisms responsible for severe pulmonary diseases whose development is encouraged by the presence of chronic obstructive pulmonary disease (COPD) and related immunosuppression. CASE REPORTS We report the cases of two patients, both alcoholics with emphysematous COPD, who developed chronic pulmonary aspergillosis following atypical mycobacterial infection. Patient 1 developed chronic necrotising aspergillosis several months after the diagnosis of infection with Mycobacterium avium. Patient 2 developed an aspergilloma several weeks after the diagnosis of infection with Mycobacterium xenopi. The association of these two pathologies presents diagnostic and therapeutic problems that are discussed. CONCLUSION The development of Aspergillus pulmonary disease may complicate atypical mycobacterial infections and explain a poor response to treatment. Our two case reports suggest that a systematic search should be made for pulmonary aspergillosis during the follow-up of patients with atypical mycobacterial infection.

Abstract
INTRODUCTION Löffler syndrome is an acute, pneumonia of unknown ethiology. This disease is not often associated with bronchial asthma. In its asymptomatic form, this disease is reversible, transient, self-limited with no requests for specific therapy regimen. In the symptomatic form, as well as during its progression, treatment with steroids is very effective. Furthermore, in both acute eosinophilic and idiopathic chronic eosinophilic form, this kind of therapy ensures survival. CASE REPORT The case of a 53-year-old Caucasian woman was presented with 2-month history of low grade fever, shortness of breath, cough and reduced exercise tolerance. Although she had an allergic accident on insects in history, non allergy reactions as well as an obstructive disease with that kind of origin were not detected on admission. The diagnosis of simple eosinophilic pneumonia (SEP) (Löffler's syndrome) was confirmed by transbronchial biopsy and by sternal testing. The peripheral blood eosinophilia with pulmonary eosinophilic infiltrates on X ray chest radiography were observed during clinical examination. Biopsy specimen of the lung parenchym showed changes associated with Löffler's syndrome. The diagnosis was, also, confirmed according to the radiographic findings of unilateral migratory infiltrates consistent pneumonia. DISCUSSION Churg Strauss syndrome (CSS) has to be considered in this differential diagnosis. Frequently, this disease has extrinsic bronchial asthma with eosinophilic pneumonia in history: asthma is often associated with allergic bronchopulmonary aspergillosis. In the reported case, treatment with steroids resulted in a marked clinical improvement compared to nonsteroid therapy.

Abstract
Eosinophilic pneumonia was confirmed by bronchoalveolar lavage fluid examination and transbronchial lung biopsy. Aspergillus niger was cultured from the patient's pharyngeal swab and bronchoalveolar lavage fluid. Inhalation bronchoprovocation test with A. niger antigen was positive. Although the patient's condition improved promptly with 10 mg/day prednisolone administration, dry cough recurred approximately 2 months after completion of this therapy. Severe coughing disappeared on oral cleansing with 300 mg/day amphotericin B, and he recovered completely on 100 mg/day amphotericin B administration. Oral cleansing with amphotericin B may be efficacious in preventing relapses of eosinophilic pneumonia caused by allergic reaction to fungal antigen.

Abstract
A 36-year-old man was transferred to the hospital for further evaluation of pulmonary infiltration. A diagnosis of acute eosinophilic pneumonia (AEP) was confirmed by clinical symptoms, bronchoalveolar lavage, and computed tomography findings. Skin tests with fungal antigens were performed by intradermal injection. Both the Arthus (8 h) and delay (24 h)-type skin tests were positive for only Candida albicans. A lymphocyte-stimulating test was also positive for C. albicans. The etiology of the AEP was confirmed by a C. albicans inhalation provocation test. In addition, peripheral blood mononuclear cells obtained from the patient produced Interleukin-5 following C. albicans stimulation. This is the first report of C. albicans as a probable cause of AEP. Evaluation of allergy to C. albicans should be performed in AEP before diagnosing the cause as idiopathic.

Abstract
For most patients who have suspected drug-induced eosinophilic lung disease, the history provides a presumptive diagnosis that can be confirmed by pulmonary findings and eosinophilia after cessation of the drug. As new drugs are developed and released for clinical use, many will result in eosinophilic lung disease in susceptible patients. Therefore, development of pulmonary abnormalities in conjunction with blood or lung eosinophilia after prescription ofa newly released medication should raise the possibility of drug-induced lung disease, even if that medication has not yet been reported to cause eosinophilic lung disease. In all patients, the diagnosis requires exclusion of other causes of eosinophilic lung disease by history, and, if necessary, laboratory testing or lung biopsy.

Abstract
We describe a patient who presented with dry cough, low-grade fever, and focal patchy shadow of pulmonary infiltrates. Remarkably, the prospective etiological agent, Saccharomyces cerevisiae was purely and repeatedly cultured from her sputum. Allergic bronchopulmonary mycosis (ABPM) was diagnosed based on clinical, serological, and pathological criteria. Although the patient described here satisfied only three of the criteria, the conclusion that the allergic bronchopulmonary disease in our case was induced by S. cerevisiae was made based on the following evidence: 1) S. cerevisiae was repeatedly isolated from the patient's sputum, 2) anti-S. cerevisiae antibody was detected in her serum, and 3) bronchoprovocation test to S. cerevisiae antigen was positive. We present here a case of allergic bronchopulmonary fungal disease caused by S. cerevisiae antigen.

Abstract
Few reports of chronic eosinophilic pneumonia (CEP) in the pediatric population can be found in the literature. Our patient, a 16-year-old male subject presenting with signs and symptoms of CEP, prompted a survey of pediatric pulmonary training centers in the United States to determine the prevalence of eosinophilic pneumonia. The survey showed a low prevalence of acute eosinophilic pneumonia and CEP in the pediatric population, with an overall male/female ratio of 1.6:1.

Abstract
Our aim in the study was to investigate the pathogenesis of eosinophilic inflammation in patients with acute eosinophilic pneumonia (AEP), and to determine the levels of (1-->3)-beta-D-glucan, which is one of the major components of the cell wall of most fungi, in the BAL fluid (BALF) of those patients with AEP. Six patients with AEP and five patients with chronic eosinophilic pneumonia (CEP) that was in the acute stage and had been newly diagnosed, and nine healthy subjects from the Kurume University School of Medicine and the Social Institute Tagawa Hospital between 1995 and 2001 were entered into the study. In AEP patients, (1-->3)-beta-D-glucan was detected in BALF, and these findings were compared with BALF findings in patients with CEP as well as with those in healthy subjects. In the BALF of AEP patients, the mean concentration of (1-->3)-beta-D-glucan was significantly higher (p < 0.05) than that of CEP patients as well as healthy subjects. In patients with AEP, the mean concentration of (1-->3)-beta-D-glucan in BALF was significantly higher (p < 0.05) than that in the blood. In four of six patients with AEP, we measured serial changes in (1-->3)-beta-D-glucan levels, and the level of (1-->3)-beta-D-glucan in the BALF decreased with clinical improvement at follow-up. We concluded that inhaled (1-->3)-beta-D-glucan may be involved in the mechanisms of pulmonary inflammation in patients with AEP.

Abstract
A fatal case of idiopathic eosinophilic pneumonia with acute lung injury is described. The patient required treatment with mechanical ventilation and intravenous corticosteroids, however, she died on the third hospital day. At autopsy, both exudative and proliferative phases of diffuse alveolar damage were observed bilaterally. Marked eosinophilic infiltrate was noted in the alveolar wall and within the alveolar cavities with occasional abscess-like features. To our knowledge, this is the first report of fatal acute eosinophilic pneumonia, and provides important information for the management of this condition.

Abstract
It has been proposed that acute eosinophilic pneumonia (AEP), which is characterized by the absence of recurrence, is associated with cigarette smoking (CS), because Japanese patients with AEP are young and have a high incidence of short-term smoking history. However, there has been no direct evidence that CS causes AEP. We hypothesized that tolerance might develop against repeated resumption of smoking cigarettes in CS-induced AEP cases. In this connection, we challenged a patient with CS-induced AEP with repeated resumption of CS, and it was demonstrated that CS induced AEP in conjunction with tolerance to repeated resumption of smoking.

Abstract
Given the variability in rate of radiographic resolution, it remains controversial to decide when to initiate an invasive diagnostic work-up for nonresolving or slowly resolving pulmonary infiltrates. In immunocompetent patients who present with classical features of CAP (i.e., fever, chills, productive cough, new pulmonary infiltrate), clinical response to therapy is the most important determinant for further diagnostic studies. Within the first few days, persistence or even progression of infiltrates on chest radiographs is not unusual. Defervescence, diminished symptoms, and resolution of leukocytosis strongly support a response to antibiotic therapy, even when chest radiographic abnormalities persist. In this context, observation alone is reasonable, and invasive procedures can be deferred. Serial radiographs and clinical examinations dictate subsequent evaluation. In contrast, when clinical improvement has not occurred and chest radiographs are unchanged or worse, a more aggressive approach is warranted. In this setting, we advise fiberoptic bronchoscopy with BAL and appropriate cultures for bacteria, legionella, fungi, and mycobacteria. When endobronchial anatomy is normal and there is no purulence to suggest infection, TBBs should be done to exclude noninfectious causes (discussed earlier) or infections attributable to mycobacteria or fungi. An aggressive approach is also warranted in patients who are clinically stable or improving when the rate of radiographic resolution is delayed. As discussed earlier, what constitutes excessive delay is controversial, and depends upon the acuity of illness, specific pathogen, extent of involvement (i.e., lobar versus multilobar), comorbidities, and diverse host factors. Stable infiltrates even 2 to 4 weeks after institution of antibiotic therapy does not mandate intervention provided patients are improving clinically. Invasive techniques can also be deferred when unequivocal, albeit incomplete, radiographic resolution can be demonstrated. Lack of at least partial radiographic resolution by 6 weeks, even in asymptomatic patients, however, deserves consideration of alternative causes (e.g., endobronchial obstructing lesions, or noninfectious causes). Fiberoptic bronchoscopy with BAL and TBBs has minimal morbidity and is the preferred initial invasive procedure for detecting endobronchial lesions or substantiating noninfectious causes. The yield of bronchoscopy depends on demographics, radiographic features, and pre-test likelihood. In the absence of specific risk factors, the incidence of obstructing lesions (e.g., bronchogenic carcinomas, bronchial adenomas, obstructive foreign body) is low. Bronchogenic carcinoma is rare in nonsmoking, young (< 50 years) patients but is a legitimate consideration in older patients with a history of tobacco abuse. Non-neoplastic causes (e.g., pulmonary vasculitis, hypersensitivity pneumonia, etc.) should be considered when specific features are present (e.g., hematuria, appropriate epidemiologic exposures). Ancillary serologic tests or biopsies of extrapulmonary sites are invaluable in some cases. In rare instances, surgical (open or VATS) biopsy is necessary to diagnose refractory or non-resolving "pneumonias."

Abstract
There are clinically different types of eosinophilic pneumonia (EP) but no study to date has compared pulmonary inflammatory cells between different types of EP, such as acute eosinophilic pneumonia (AEP), chronic eosinophilic pneumonia (CEP) and drug-induced eosinophilic pneumonia (drug-EP). The present study compared bronchoalveolar lavage fluid (BALF) cell findings to elucidate whether the profiles of the pulmonary inflammatory cells were different among the three types of EP. Clinical records of 28 patients with EP, consisting of eight AEP patients, 10 CEP patients and 10 drug-EP patients, were examined retrospectively. The differential cell counts, the CD4+/CD8+ ratio of lymphocytes, the percentage of HLA-DR+ in CD4+ and CD8+ lymphocytes, and the mean number of nuclear segmentations in cosinophils in BALF were compared among the three types of EP. The numbers of total cells, lymphocytes, neutrophils and eosinophils in BALF from patients with AEP were increased compared with those from normal subjects, and patients with CEP and drug-EP. The CD4+/CD8+ ratio of the BALF lymphocytes in patients with AEP, which exceeded 1.0 in all patients, was significantly higher than that in normal subjects. The percentages of HLA-DR+ cells in CD8+ lymphocytes in BALF from patients with CEP were significantly higher than those from patients with AEP and drug-EP. There was no significant difference in the mean number of nuclear segmentations in eosinophils in BALF among the three types of EP. The BALF cell findings in patients with EP showed some characteristics in accordance with type of EP. It is suggested that pulmonary neutrophils and lymphocytes, rather than eosinophils, may be related to the pathogenesis of the different types of EP.

Abstract
We report a case of acute eosinophilic pneumonia associated with adult respiratory distress syndrome in an adolescent. This entity should be considered in the differential diagnosis in previously well children and adolescents who are seen with unexplained respiratory failure and who have many eosinophils in bronchoalveolar lavage fluid. Prompt recognition of this rapidly reversible noninfectious disorder and institution of corticosteroids may be lifesaving.

Abstract
We describe a patient who presented with hypoxemia and diffuse bilateral pulmonary infiltrates. The diagnosis of eosinophilic pneumonia was confirmed by bronchoalveolar lavage and transbronchial lung biopsy. The remarkable characteristic was reappearance of the symptoms on the patient's return home, suggesting the existence of etiologic agents in his house. An environmental survey of the patient's house yielded Alternaria alternata. A high titer of anti-A. alternata antibody (IgG) was detected in his serum, and the inhalation bronchoprovocation test with A. alternata antigen was positive. This case indicates that A. alternata is a probable cause of eosinophilic pneumonia.

Abstract
Idiopathic acute eosinophilic pneumonia (AEP) is an acute febrile illness that may be mistaken for an infectious pneumonia. Patients are often young and otherwise healthy. Clues to considering this disorder in a differential diagnosis include the acuity and severity of the clinical presentation and an initial chest X-ray with diffuse infiltrates, often interstitial, and the presence of Kerley B lines and/or evidence of pleural fluid. The diagnosis can be made through examination of bronchoalveolar lavage fluid in most cases, with careful exclusion of other similar eosinophilic lung disease. Although it can lead to life-threatening respiratory failure, AEP is easily treatable with corticosteroids. This disease has not been reported to recur in any patients to this point.

Abstract
BACKGROUND Although the pathogenesis of acute eosinophilic pneumonia remains largely unknown, it has been suggested that it may include a hypersensitivity phenomenon induced by inhaled environmental antigens. METHODS To investigate this possibility, we studied the effect of environmental challenges in three patients with acute eosinophilic pneumonia. Symptoms and laboratory findings were evaluated before and after the challenge tests in the patient's homes and their places of work. RESULTS After the provocation challenges to their homes, all three patients developed fever, cough, and fatigue and two of them presented with dyspnea. Inspiratory crackles became audible in all cases, and there was a decreased Pao2 level in two. Similar challenges at their workplaces were negative. After moving out of their homes, the patients engaged in their usual work but had no recurrent episodes. CONCLUSIONS These results suggest that environmental factors in the home can be the cause of acute eosinophilic pneumonia. In order to elucidate the pathogenesis of the disease, it is important to further investigate environmental factors.

Abstract
Invasive aspergillosis is seldomly described in systemic lupus erythematosus. We present two cases of aspergillosis and review 21 cases reported between 1957 and 1994. The typical clinical presentation is fever and cough in a hospitalized SLE patient previously treated with corticosteroids, immunosuppressors, and broad-spectrum antibiotics. Unlike aspergillosis in other conditions, granulocytopenia is uncommon. Chest radiographs show diffuse or patchy infiltration of lung fields. Diagnosis was suspected premortem in 2 patients. Aspergillus fumigatus was identified or isolated in sputum or parenchimal tissues in the majority of cases. Twenty-two patients died (95%). The finding of hyphae in the sputum of a systemic lupus erythematosus patient with a suggestive clinical picture should lead to bronchoscopy, bronchoalveolar lavage, and lung biopsy. Proof of diagnosis will come from the demonstration of hyphae in tissues and isolation of aspergillus from tissue cultures. Long-term therapy with amphotericin B alone or in combination with fluorocytosine or itraconazole may help improve survival.

Abstract
Invasive pulmonary aspergillosis is a frequent complication in immunocompromised patients. The role of the prolonged use of steroids in predisposing to invasive aspergillosis has been recognized, but exceptionally described in asthmatic patients. We report the case of a 59-year-old woman with bronchial asthma treated with steroid therapy for a long time, who developed an invasive pulmonary aspergillosis with an unusual combination of invasive and allergic disease. It seems reasonable to think that allergic disease due to allergic bronchopulmonary aspergillosis (ABPA) preceded the terminal invasive process. Adjunctive therapy with antifungal agents in patients with ABPA is considered, since there is the risk of an invasive pulmonary aspergillosis.

Abstract
To better characterize idiopathic eosinophilic pneumonia (IEP), we studied the clinical and laboratory features of 27 patients. Patients with IEP could be divided into those with chronic eosinophilic pneumonia (CEP) (n = 14) and acute eosinophilic pneumonia (AEP) (n = 13). CEP was characterized by (1) multiple and dense areas of consolidation on chest radiographs and computed tomographic (CT) scans, (2) persistent symptoms, (3) a requirement for steroid therapy, and (4) possible relapses. On the other hand, AEP was characterized by (1) diffuse ground-glass and micronodular infiltrates on radiographs and CT scans (in mild cases, the lesions were sparse or localized), (2) acute onset with high fever, (3) spontaneous improvement, and (4) no relapse. In addition, peripheral blood eosinophil count was significantly higher in patients with CEP than in patients with AEP at the first examination. However, the eosinophil fraction also became markedly elevated during the subsequent courses of AEP. Analysis of bronchoalveolar lavage fluid revealed that the percentage of eosinophils was higher in patients with CEP than that in patients with AEP, whereas the percentage of lymphocytes was significantly greater in patients with AEP than patients with CEP. It was also noted that 75 percent of patients with CEP and 82 percent of patients with AEP had allergic diathesis, suggesting that both conditions are likely to occur in atopic individuals.
