ObjectiveTo investigate the clinical features of patients who went through Nocardia co-infection with Aspergillus in lung.MethodsClinical data of 3 pulmonary nocardiosis patients complicated with aspergillosis from China-Japan Hospital during June 2015 and May 2016 were retrospectively analyzed. Nine related literatures found at PubMed were reviewed and they all were case report. No Chinese literature was found at Wanfang data and Chinese Journal Fulltext Database.ResultsAll of the 3 patients were diagnosed as pulmonary nocardiosis by etiological detection, at the same time meeting the diagnostic criteria of invasive pulmonary aspergillosis. Two cases were infected with Aspergillus fumigatus. Aspergillus was not detected in the third case, but the galactomannan of serum and bronchoalveolar lavage fluid significantly increased.ConclusionPulmonary nocardiosis complicated with aspergillosis trends to occur in immunocompromised patients, and pathogen detection is important for diagnosis.
Co-infection with severe influenza and bacterial is well known, but in recent years, more and more studies report that aspergillus have been identified as important pathogens, secondary only to bacteria in severe influenza. Influenza-associated aspergillus (IAA) brings a high death rate and heavy burden to our country. Therefore, early diagnosis and effective treatment are needed. In order to better understand IAA, this review summarizes the available literature on the association of IAA, including epidemiology, diagnosis and treatment.
ObjectiveTo investigate the clinical manifestations, diagnosis and treatments of allergic bronchopulmonary aspergillosis (ABPA).
MethodsThe clinical data of four cases of ABPA diagnosed in our department between 2009 and 2014 were analyzed. The related literature was also reviewed.
ResultsABPA tends to occur in people with chronic lung diseases, such as asthma and cystic fibrosis. The main clinical manifestations are wheezing, fever, cough, and sputum production. Laboratory examinations include immediate Aspergillus skin test reactivity, elevated total serum IgE and Aspergillus specific IgE and IgG antibodies, and peripheral blood eosinophilia. Radiological findings include recurrent chest roentgenographic infiltrates and central bronchiectasis. Treatments involve corticosteroids and antifungal therapy with itraconazole.
ConclusionsABPA is easy to misdiagnosis clinically. It should be considered in patients with poor controlled asthma and asthmatic patients with acute pulmonary infiltrates. Early diagnosis and proper treatment can minimize lung injury from ABPA and improve outcomes.
Objective To retrospectively analyze the clinical features of invasive pulmonary aspergillosis (IPA) in intensive care unit (ICU), so as to improve the level of clinical diagnosis and treatment. Methods A total of 81 patients diagnosed as IPA from March, 2017 to March, 2022 in the ICU of The First Affiliated Hospital of USTC, Division of Life Sciences and Medicine, University of Science and Technology of China were selected as infection group. A total of 81 non-IPA patients with pulmonary infection and Aspergillus negative sputum culture were selected as the control group. The host factors, Acute Physiology and Chronic Health Assessment Ⅱ score at admission, underlying diseases, clinical symptoms and signs, relevant laboratory test results, and lung CT findings were compared between the two groups. Univariate analysis and multivariate conditional logistic regression analysis were used to identify the risk factors for the occurrence of pulmonary aspergillosis in IPA patients in ICU. At the same time, the types of aspergillus in the IPA group and the outcomes of the two groups at 28 days after ICU admission were analyzed. Results Of the 81 IPA patients, 4 were proven diagnosed and 77 were putative diagnosed. IPA patients were mainly infected with Aspergillus fumigatus and Aspergillus flavus. Symptoms and signs such as fever, cough and expectoration, dyspnea and pulmonary rales occurred in both groups. The level of procalcitonin in IPA group was higher than that in non-IPA group, and the difference was statistically significant (P=0.016). The positive rate of serum galactomannan antigen test (GM test) in the IPA group was higher than that in the non-IPA group, and the differences was statistically significant (P=0.000). The incidence of pulmonary imaging cavities in IPA group was higher than that in non-IPA group, and the difference was statistically significant (P=0.022). Univariate analysis showed that central venous catheterization, septic shock, complete parenteral nutrition, chronic obstructive pulmonary disease, and immunosuppression were risk factors for IPA (P<0.05); Multivariate conditional logistic regression analysis showed that complete parenteral nutrition, chronic obstructive pulmonary disease, and immunosuppression were independent risk factors for IPA (P<0.05). The 28-day fatality rate in IPA group was higher than that in non-IPA group (55.6% vs. 34.6%, P=0.007). Conclusions IPA patients have no specific clinical symptoms and signs, and are mainly infected with Aspergillus fumigatus and Aspergillus flavus; GM test has guiding significance for the diagnosis of IPA. Serum GM test and pulmonary imaging have cavity findings that are helpful for the diagnosis of IPA. Patients with a history of chronic obstructive pulmonary disease, immunosuppression, or complete parenteral nutrition need to be on high alert for the possibility of IPA during ICU stay.

Methods The clinical data of three patients with pulmonary aspergillosis from January to April 2010 were retrospectively analyzed, and the misdiagnostic causes were analyzed. Result No specific clinical and imaging findings were found in the three patients, and pulmonary aspergillosis was finally diagnosed according to the pathological biopsy. Conclusion Pulmonary aspergillus lacks specific clinical and imaging manifestations; early fiberoptic bronchoscopy or pulmonary biopsy may improve the rate of accurate diagnosis.
Objective
To improve the diagnosis and treatment of pulmonary infiltration with eosinophilia (PIE).
Methods
Patients who were diagnosed with PIE in the First Affiliated Hospital of Guangzhou Medical University from January 2004 to December 2013 were recruited and retrospectively analyzed. Data of etiology, clinical manifestation, imaging and pathological features were recorded.
Results
pulmonary eosinophilic granuloma (PEG) (n=2), eosinophilic granulomatosis with polyangiitis (EGPA) (n=7), L?ffler syndrome (n=4), allergic bronchopulmonary aspergillosis (ABPA) (n=16), and chronic eosinophilic pneumonia (CEP) (n=19). There were 27 males and 21 females. 47.9% of the PIE patients were diagnosed as asthma and treated with regular treatment but had not been controlled well. PEG was characterized with wheeze and anhelation in clinical manifestations, unelevated blood eosinophil counts and percentage, significant small airway abnormalities in lung function, diffuse pneumonectasis in Chest CT, and appearance of eosinophil cells in alveole. EGPA shows dyspnea and cough in clinical manifestations, as well as other organs function damaged, unelevated blood eosinophil counts and percentage, significant FEV1/FVC and small airway abnormalities in lung function, tree-in-bud in Chest CT, appearance of eosinophilic granuloma outside blood vessels. L?ffler syndrome also showed cough, shorter course of disease, normal lung function and diffusion. ABPA showed wheeze and cough, 31.3% of them with hemoptysis, normal blood eosinophil count, central bronchiectasis in Chest CT. CEP also showed dyspnea and cough. 21.1% of CEP patientshad chest pain, increasing sputum eosinophil percentage compare with blood eosinophil percentage, and small airway abnormalities in lung function.
Conclusions
Most of PIE patients are diagnosed as asthma but haven’t gotten well controlled under the regular anti-asthmatic treatment. Patients with PIE have increasing eosinophil counts and decreasing lung function. The diagnosis of PIE still depends on clinical manifestation, laboratory test, imaging and pathological examination.
