Abstract
We herein report a case of recurrent infection caused by Verruconis gallopava, which is known to cause fatal phaeohyphomycosis. A 71-year-old man presented with a fever, and computed tomography revealed right chest wall thickening. Eleven years earlier, he had undergone autologous peripheral blood stem cell transplantation for a hematological malignancy. One year earlier, he had undergone excision of a solitary pulmonary nodule, from which had been detected V. gallopava. On this occasion, right chest wall surgery was performed to investigate the cause of the fever, which led to the diagnosis of recurrent infection. Even if a localized lesion is excised, additional antifungal therapy should be performed.

Kosmidis C, Achira M, Yong J, Harris C, Bazaz R. Aspergillus nodules: Natural history and the effect of antifungals. Mycoses 2024; 67:e13716. [PMID: 38503713 DOI: 10.1111/myc.13716] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/29/2023] [Revised: 03/04/2024] [Accepted: 03/11/2024] [Indexed: 03/21/2024]
Abstract
BACKGROUND Aspergillus nodules are classified as a subset of chronic pulmonary aspergillosis. The optimal management approach is not known as their natural evolution following biopsy, the rate of progression to chronic cavitary pulmonary aspergillosis (CCPA) and the effect of antifungal treatment have not been described. OBJECTIVES To describe the clinical course of patients diagnosed with Aspergillus nodules and the effect of antifungal treatment. PATIENTS/METHODS We present a series of 23 patients with histologically confirmed Aspergillus nodules and describe serial imaging, antifungal treatment and progression to other diagnoses. RESULTS Thirteen patients were diagnosed after a CT-guided biopsy and 10 after surgical resection. Among those who had CT-guided biopsy, 8 did not receive antifungal treatment; the nodule was stable or smaller in all cases on subsequent CT scan after a mean of 15.5 months. However, one patient developed squamous cell carcinoma after 16 months and another developed CCPA after 7 months. Among the 5 patients who received antifungals for at least 4 weeks, the nodule was smaller in 1 and stable in 4. One patient developed CCPA 3 years after the biopsy. No patient who had a surgical resection subsequently had a CCPA diagnosis. CONCLUSION Most Aspergillus nodules remained stable or improved following biopsy, irrespective of the effect of antifungals. However, CCPA can develop occasionally in patients with Aspergillus nodules and ongoing radiological follow-up may be warranted when the nodule is not resected.

Abstract
Chronic pulmonary aspergillosis (CPA) refers to a number of clinical syndromes resulting from the presence and local proliferation of Aspergillus organisms in the lungs of patients with chronic lung disease. CPA is more common than was realized two decades ago. Recognition remains poor, despite recent studies from many countries highlighting the high prevalence in at-risk populations. In low- and middle-income countries, CPA may be misdiagnosed and treated as tuberculosis (TB). In addition, CPA may develop following successful TB treatment. The coronavirus disease pandemic has resulted in significant disruption to provision of TB care, likely leading to more extensive lung damage, which could increase the risk for CPA.Although CPA refers to various syndromes, the classic presentation is that of chronic cavitary pulmonary aspergillosis, which manifests as one or more progressive cavities with or without a fungal ball, accompanied by systemic and respiratory symptoms for at least 3 months. Diagnosis relies on Aspergillus immunoglobulin G in serum, as sputum culture lacks sensitivity. Differential diagnosis includes mycobacterial infection, bacterial lung abscess or necrotizing pneumonia, lung cancer, and endemic fungi.The aim of antifungal treatment in CPA is to improve symptoms and quality of life, and to halt progression, and possibly reverse radiological changes. Current recommendations suggest treatment for 6 months, although in practice many patients remain on long-term treatment. Improvement may manifest as weight gain and improvement of symptoms such as productive cough, hemoptysis, and fatigue. Surgical management should be considered in cases of diagnostic uncertainty, in significant hemoptysis, and when there is concern for lack of response to therapy. Itraconazole and voriconazole are the first-line azoles, with more experience now accumulating with posaconazole and isavuconazole. Side effects are frequent and careful monitoring including therapeutic drug monitoring is essential. Intravenous antifungals such as echinocandins and amphotericin B are used in cases of azole intolerance or resistance, which often develop on treatment. Relapse is seen after completion of antifungal therapy in around 20% of cases, mostly in bilateral, high-burden disease.Several research priorities have been identified, including characterization of immune defects and genetic variants linked to CPA, pathogenetic mechanisms of Aspergillus adaptation in the lung environment, the contribution of non-fumigatus Aspergillus species, and the role of new antifungal agents, immunotherapy, and combination therapy.

Abstract
Pulmonary aspergillosis constitutes an increasingly prevalent and potentially fatal complex of mycotic diseases, caused by different species of Aspergillus. The broad spectrum of pathological manifestations associated with pulmonary aspergillosis necessitates a differentiation of commensalism from saprophytic colonization, hypersensitivity reactions, and true invasive infections, which highlights the importance of histopathology as a gold standard in a diagnostic setting. For the past decades, changes in terminology and contradicting contributions from different diagnostic disciplines have made the classification of pulmonary aspergillosis rather confusing. This review offers a categorization of aspergillosis lesions based on what can be histopathologically identified and distinguished, differentiating between acute invasive infection and forms of subacute, chronic, and allergic diseases and coinfections, and summarizes important manifestations of lesions associated with the different forms of pulmonary aspergillosis.

Abstract
A pulmonary Aspergillus nodule is a rare subtype of chronic pulmonary aspergillosis. The diagnosis is difficult and is histological. There are only a few reports on such cases. Here, we report five cases of pulmonary Aspergillus nodules confirmed by surgery and pathology in immunocompetent patient and review the literature. Among the five patients in this group, three were females and two were males, aged 44-73 years old. Two cases had hemoptysis onset, and three cases were found to have a slow disease course on chest CT during imaging, ranging from months to years. The white blood cell count, carcinoembryonic antigen, and blood Galactomannan (GM) tests in five cases were all within normal range. Four cases had normal blood C-reactive protein, and one case had an increase. On imaging, there were two cases in the upper lobe of the right lung, two cases in the lower lobe of the left lung, one case in the upper lobe of the left lung, three cases were solitary nodular shadows, and two cases were nodular shadows with cavity formation, including one case with calcification, four cases with bronchial dilation shadows, and one case with gas containing cavity shadows. Five cases were treated with surgical resection and confirmed by histopathological examination. All five patients did not receive antifungal treatment after surgery, and there was no recurrence of Aspergillus nodules during regular follow-up.

Diagnostic Laboratory Features and Performance of an Aspergillus IgG Lateral Flow Assay in a Chronic Pulmonary Aspergillosis Cohort. Microbiol Spectr 2023; 11:e0026423.

Abstract
Chronic pulmonary aspergillosis (CPA) is a chronic and progressive fungal disease with high morbidity and mortality. Avoiding diagnostic delay and misdiagnosis are concerns for CPA patients. However, diagnostic practice is poorly evaluated, especially in resource-constrained areas where Aspergillus antibody testing tools are lacking. This study aimed to investigate the diagnostic laboratory findings in a retrospective CPA cohort and to evaluate the performance of a novel Aspergillus IgG lateral flow assay (LFA; Era Biology, Tianjin, China). During January 2016 and December 2021, suspected CPA patients were screened at the Center for Infectious Diseases at Huashan Hospital. A total of 126 CPA patients were enrolled. Aspergillus IgG was positive in 72.1% with chronic cavitary pulmonary aspergillosis, 75.0% with chronic necrotizing pulmonary aspergillosis, 41.7% with simple aspergilloma, and 30.3% with Aspergillus nodule(s). The cavitary CPA subtypes had significantly higher levels of Aspergillus IgG. Aspergillus IgG was negative in 52 patients, who were finally diagnosed by histopathology, respiratory culture, and metagenomic next-generation sequencing (mNGS). Sputum culture was positive in 39.3% (42/107) of patients and Aspergillus fumigatus was the most common species (69.0%, 29/42). For CPA cohort versus controls, the sensitivity and specificity of the LFA were 55.6% and 92.7%, respectively. In a subgroup analysis, the LFA was highly sensitive for A. fumigatus-associated chronic cavitary pulmonary aspergillosis (CCPA; 96.2%, 26/27). Given the complexity of the disease, a combination of serological and non-serological tests should be considered to avoid misdiagnosis of CPA. The novel LFA has a satisfactory performance and allows earlier screening and diagnosis of CPA patients. IMPORTANCE There are concerns on avoiding diagnostic delay and misdiagnosis for chronic pulmonary aspergillosis due to its high morbidity and mortality. A proportion of CPA patients test negative for Aspergillus IgG. An optimal diagnostic strategy for CPA requires in-depth investigation based on real-world diagnostic practice, which has been rarely discussed. We summarized the clinical and diagnostic laboratory findings of 126 CPA patients with various CPA subtypes. Aspergillus IgG was the most sensitive test for diagnosing CPA. However, it was negative in 52 patients, who were finally diagnosed by non-serological tests, including biopsy, respiratory culture, and metagenomic next-generation sequencing. We also evaluated a novel Aspergillus IgG lateral flow assay, which showed a satisfactory performance in cavitary CPA patients and was highly specific to Aspergillus fumigatus. This study gives a full picture of the diagnostic practice for CPA patients in Chinese context and calls for early diagnosis of CPA with combined approaches.

Abstract
Chronic obstructive pulmonary disease (COPD) is a chronic airway non-specific inflammatory disease characterised by airway obstruction and alveolar destruction. In recent years, due to the extensive use of antibiotics, glucocorticoids, immunosuppressants and other drugs, pulmonary fungal infection in patients with AECOPD, especially aspergillus infection, has gradually increased. The forms of aspergillus infection present in COPD patients include sensitisation, chronic pulmonary aspergillosis (CPA) and invasive pulmonary aspergillosis (IPA). This review will summarise diagnostic and treatment of aspergillus in COPD patients.

Abstract
Chronic pulmonary aspergillosis (CPA) is an important infection to understand in survivors of pulmonary tuberculosis (PTB). However, limited data are available regarding CPA development and its predisposing factors following PTB. We investigated the development of, and the predisposing factors for, CPA following the completion of PTB treatment. A total of 345 patients, with newly diagnosed culture-positive PTB (between January 2015 and December 2018), were included. Enrolled cases were categorized into four groups (persistently seronegative, seroconversion, seroreversion, and persistently seropositive) according to serological changes in their anti-Aspergillus IgG antibodies before and after PTB treatment. The patients were followed up for a median of 25.8 months. Ten (10/345, 2.9%) patients developed CPA at a median of 13.5 months after treatment completion, including seven (7/24, 29.2%) and three (3/73, 4.1%) in the seroconversion and persistently seropositive groups, respectively. Upon multivariate analysis, seroconversion of anti-Aspergillus IgG antibody (adjusted hazard ratio [HR], 25.21; 95% confidence interval [CI], 6.11–103.99; p < 0.001) and diabetic status (adjusted HR, 7.54; 95% CI, 1.93–29.50; p = 0.004) were independently associated with CPA development. The development of CPA in patients with PTB was observed in 2.9% of patients during post-treatment follow-up, and this was significantly associated with both the seroconversion of anti-Aspergillus IgG antibody and diabetes characteristics.

Abstract
Lung granulomas are uncommon in Thailand. The disease typically develops from an occupational environment and is mostly caused by infection. Herein is a case report of a female patient, aged 48, working as a nurse in an Accident and Emergency Department at a hospital. Eighteen years prior to admission the patient was diagnosed with myasthenia gravis and pulmonary tuberculosis. The chest X-ray and CT scans showed a solitary pulmonary nodule in the lower left lung. The patient received an open thoracotomy with a left lobectomy. Granulomatous and nonseptate hyphae were found in the pathology diagnosis. The patient was thus diagnosed as having a lung granuloma. The galactomannan antigen test was positive. The solitary pulmonary nodule-found from the use of a Polymerase Chain Reaction (PCR) test-was an Aspergillus spp. The fungus culture was collected from air samples. The air samples were collected by the impaction technique using a microbial air sampler. Three types of Aspergillus spp. were found as well as Penicillium spp. and Monilia sitophila. The Aspergillus spp. was a match for the patient's disease. The patient was diagnosed as having a lung granuloma possibly Aspergillus nodule which was caused by airborne Aspergillus spp. from the occupational environment.
