Chronic pulmonary aspergillosis: rationale and clinical guidelines for diagnosis and management

Chronic cavitary pulmonary aspergillosis in an immunocompetent child

Chronic pulmonary aspergillosis (CPA) is a progressive and destructive disease of the lung parenchyma. We report a 9-year-old boy diagnosed with CPA with a positive Aspergillus IgG and chest imaging of cavitary lung lesions. He was treated with oral Itraconazole with significant improvement. This shows that an index of suspicion should be heightened in the paediatric population with cavitary lung lesions because not all cavitary lung lesions are caused by Mycobacterium tuberculosis.

Aspergilloma Morphology on Computed Tomography Angiography and its Clinical Impact in Patients of Haemoptysis

Amongst various manifestations of pulmonary aspergillosis, chronic pulmonary aspergillosis (CPA) is the most common. We conducted this study to identify different morphological forms of CPA, on computed tomography angiography (CTA), and to correlate these with clinical presentation, as well as, associated imaging features. The study design was cross-sectional, with a final sample size of 65 patients, recruited over a period of 2years from January 2017 to October 2018. Patients with past history of tuberculosis (TB), presenting with haemoptysis and found to have aspergilloma on computed tomography and lab tests were included in the study. All patients underwent CTA for evaluation of haemoptysis. Three morphological types of intracavitary aspergilloma on imaging were identified: type 1-nodular soft tissue along the cavity-wall, type-2 soft tissue density with multiple air lucencies and type-3 homogenous soft tissue opacity with air-crescent sign. Aspergilloma types were correlated with grade and duration of haemoptysis, associated imaging findings and vascularity score on CTA. Mean age of the patients was 40.97 +/- 13.69 years. As the type of aspergilloma changed from 1 to 3, there was a decrease in cavity wall thickness, peri-cavitary inflammation and vascularity. It is the type 1 and 2 aspergillomas, which caused more inflammation in the lungs, and hence recruited more abnormal vasculature. No significant correlation was found between haemoptysis severity and type of aspergilloma; type 3 aspergilloma however had longer duration of haemoptysis. In conclusion, the initial stages of formation of aspergilloma (type 1 and 2) cause more parenchymal inflammation and symptoms. The classical Monod sign is observed in the late stage of aspergilloma, since the peri-cavitary inflammation is reduced by then and thus the symptoms.

A Case of Invasive Pulmonary Aspergillosis vs. Pulmonary Aspergilloma in Immunocompromised Patient With Preexisting Lung Cavity

Subacute invasive aspergillosis (SAIA) occurs in immunocompromised patients and/or patients with preexisting pulmonary pathology. An aspergilloma is a fungus ball that occurs in preexisting lung cavities and can be relatively asymptomatic without tissue invasion. In contrast to an aspergilloma, SAIA invades local tissue and parenchyma, resulting in tissue necrosis. We present a case of a 68-year-old immunocompromised female with a past medical history of hypertension, hyperlipidemia, chronic obstructive pulmonary disease (COPD), stage IIIA adenocarcinoma, and a preexisting pulmonary cavity with chronic invasive aspergillosis vs. pulmonary aspergilloma treated with oral (PO) voriconazole. This case demonstrates that invasive aspergillosis should be considered in the differential diagnosis of any pulmonary lung lesion showing tissue invasion and expansion in an immunocompromised patient.

Lung and gut microbiomes in pulmonary aspergillosis: Exploring adjunctive therapies to combat the disease

Species within the Aspergillus spp. cause a wide range of infections in humans, including invasive pulmonary aspergillosis, chronic pulmonary aspergillosis, and allergic bronchopulmonary aspergillosis, and are associated with high mortality rates. The incidence of pulmonary aspergillosis (PA) is on the rise, and the emergence of triazole-resistant Aspergillus spp. isolates, especially Aspergillus fumigatus, limits the efficacy of mold-active triazoles. Therefore, host-directed and novel adjunctive therapies are required to more effectively combat PA. In this review, we focus on PA from a microbiome perspective. We provide a general overview of the effects of the lung and gut microbiomes on the growth of Aspergillus spp. and host immunity. We highlight the potential of the microbiome as a therapeutic target for PA.

Patient background and prognosis of chronic pulmonary aspergillosis in fibrosing interstitial lung disease

Several previous reports have shown interstitial lung disease (ILD) to be a predictor of poor prognosis in patients with chronic pulmonary aspergillosis (CPA). However, there is a lack of clarity regarding patient background and the prognostic factors in CPA associated with ILD (CPA-ILD). Therefore, we assessed these points to obtain valuable information for clinical practice. We retrospectively surveyed and collected data from 459 patients who had serum examination for anti-Aspergillus antibody. Of these patients, we extracted and investigated CPA-ILD patients. We ultimately analyzed 32 CPA-ILD patients. Patient background factors more frequently showed the patients to be older (mean: 74.9 years), male (75.0%), and to have a smoking history (71.9%). Median survival time from the diagnosis of ILD was 76.0 months, whereas that from the diagnosis of CPA-ILD was 25.5 months. No significant differences in survival were found in regard to each ILD pattern and the presence of idiopathic pulmonary fibrosis. A higher level of C-reactive protein was a significant predictor of mortality by Cox regression analysis. CPA complicating ILD is associated with poor prognosis. ILD patients with older age, male sex, and smoking history should be aware of the potential for the development of CPA in ILD. If such patients have elevated markers of inflammation, prompt induction of antifungal treatment may improve their prognosis. Clinicians should be aware of which complications of CPA may lead to a poor prognosis for any ILD not just those limited to idiopathic pulmonary fibrosis or usual interstitial pneumonia pattern.

Chronic Pulmonary Aspergillosis is Common among Patients with Presumed Tuberculosis Relapse in Ghana

Chronic pulmonary aspergillosis (CPA) may mimic pulmonary tuberculosis (PTB). The two diseases are clinically indistinguishable and may result in CPA misdiagnosed as PTB or vice versa. Although PTB is largely recognised as a differential diagnosis of CPA and often ruled out prior to CPA diagnosis, the reverse is uncommon. The aim of this study was to determine the proportion of CPA cases among patients being assessed for PTB. A cross-sectional survey was conducted among consecutive patients referred for GeneXpert Mycobacterium tuberculosis test for the diagnosis of PTB at the Korle-Bu Teaching Hospital, Accra, Ghana. Patients’ demographics, clinical and socioeconomic details were obtained using a structured questionnaire. Blood was collected for Aspergillus and HIV serology, and sputum samples obtained for Aspergillus culture. Chest radiograph was obtained, and computed tomography scan was also done for patients with positive Aspergillus serology or cavitation. CPA was defined using an algorithm developed by the Global Action for Fungal Infections (GAFFI) international expert panel. A total of 154 patients were included in the analysis, of whom 134 (87%) did not have a prior PTB diagnosis. There were 41 (26.6%) GeneXpert positive cases. CPA prevalence was 9.7% overall, but 50% in patients with a prior history of PTB and 3.7% in those without previous PTB. Although CPA is rarely considered as a differential diagnosis of PTB in Ghana, our findings show that CPA may affect half of patients being assessed for PTB relapse. Efforts to diagnose CPA should be prioritised in this patient group.

Clinical characteristics, radiological features, and disease severity of bronchiectasis according to the spirometric pattern

Bronchiectasis show various ventilatory disorders in pulmonary function. The characteristics and severity of patients with bronchiectasis according to these pulmonary dysfunctions are still very limited. This study aimed to evaluate the clinical, radiologic feature and the disease severity of patients with bronchiectasis according to spirometric patterns. We retrospectively evaluated 506 patients with bronchiectasis who underwent pulmonary lung function test (PFT) at a referral hospital between 2014 to 2021. The results showed that cylindrical type was the most common (70.8%) type of bronchiectasis on chest Computed tomography (CT), and 70% of patients had bilateral lung involvement. On the other hand, obstructive ventilatory disorder was the most common (51.6%), followed by normal ventilation (30%) and restrictive ventilatory disorder (18.4%). The modified Medical Research Council (mMRC) was highest in patients with obstructive ventilatory disorders, Modified Reiff score [median (interquartile range)] [6 (3–10), P < 0.001], FACED (FEV₁, Age, Chronic colonization, Extension, and Dyspnea) score [3 (1–4), P < 0.001], and Bronchiectasis Severity (BSI) score [8 (5–11), P < 0.001] showed significantly highest values of obstructive ventilatory disorder rather than restrictive ventilatory disorder and normal ventilation. More than half of patients with bronchiectasis had obstructive ventilatory disorder. Bronchiectasis with obstructive ventilatory disorders has more dyspnea symptom, more disease severity and more radiologic severity. There was no significant association between spirometric pattern and radiologic type, but the more severe the radiologic severity, the more severe the lung function impairment.

Therapeutic Drug Monitoring of Sputum Voriconazole in Pulmonary Aspergillosis

Voriconazole is one of the most used antifungal azoles against pulmonary aspergillosis. Therapeutic drug monitoring (TDM) of the voriconazole concentration in plasma is recommended in clinical practice guidelines to prevent treatment failure and toxicity. The aim of this study was to evaluate the feasibility and utility of TDM of the voriconazole concentration in the sputum of patients treated for pulmonary aspergillosis. Fifty sputum and 31 plasma samples were analysed with high-performance tandem mass spectrometry (HPLC-MS/MS) in 24 patients included in the study. The voriconazole concentration was simultaneously assessed in the plasma and sputum in 22 samples. The correlation between the sputum and plasma levels was estimated with a univariate linear regression model, and the observed R² was 0.86. We determined the following equation, C_sputum = 0.45 (C_plasma) + 0.21, which could predict the voriconazole concentration in plasma from sputum. TDM of the voriconazole concentration in sputum is an easy, non-invasive and accurate method with which to evaluate voriconazole exposure in patients with pulmonary aspergillosis.

Epidemiology of Aspergillosis in Cancer Patients in Taiwan

Purpose

The incidence of aspergillosis is increasing, and the risk factors for infection include cancer, admission to the intensive care unit, chronic pulmonary diseases, immunocompromised status, and taking immunomodulatory drugs. There are limited data about the incidence of aspergillosis in patients with different types of cancer. The aim of our study was to survey the incidence of aspergillosis in different cancer types from 2006 to 2017.

Patients and Methods

Data were collected from the Taiwan Cancer Registry database and International Classification of Diseases, 9th, 10th Revision, and Clinical Modification codes for diagnosing aspergillosis. Patients with a history of aspergillosis before cancer were excluded, and the secondary outcome was the risk of mortality in cancer patients with and without aspergillosis after 1 year.

Results

Among 951 cancer patients with a diagnosis of aspergillosis, there were 614 hematopoietic and reticuloendothelial system patients, 100 lung cancer patients, and 73 lymphoma cancer patients. The overall incidence rates of aspergillosis tended to increase significantly from 2006 to 2017 (from 3.50 to 13.37 per 10,000 person-years, p value: <0.0001). Regarding sex, the incidence rates of aspergillosis in males and females were 12.52 and 7.53 per 10,000 person-years, respectively. Patients with a diagnosis of aspergillosis had a 2.30-fold (95% CI: 2.14–2.48, p value: <0.0001) higher risk of mortality than those without aspergillosis.

Conclusion

The incidence of aspergillosis was increased in cancer patients, and cancer patients with aspergillosis had a significantly higher risk of mortality than those without aspergillosis.

Efficacy of Intrabronchial Voriconazole Instillation for Inoperable Pulmonary Aspergilloma: A Pilot Randomized Controlled Trial

BACKGROUND

Endobronchial administration of voriconazole is a potential therapeutic option for inoperable aspergilloma.

OBJECTIVE

This study aimed to assess the efficacy of endobronchial instillation of voriconazole for inoperable pulmonary aspergilloma.

METHOD

Patients with mild to moderate hemoptysis, due to inoperable aspergilloma, were randomized to receive either medical therapy (MT) alone or bronchoscopic instillation of voriconazole with MT and followed up till 3 months. The primary objective of this study was to compare the percentage of patients achieving reduction in the severity of hemoptysis assessed on visual analogue scale (VAS) in intervention and control arm at 3 months.

RESULTS

This study included 60 patients (female = 47) with mean (SD) age of 40.6 (13.2) years who were randomized to receive either bronchoscopic instillation of voriconazole (n = 30) or MT alone (n = 30). At 3-month follow-up, the primary objective was achieved in 26/30 (86.7%) patients in intervention group as compared to 11/30 (36.7%) in the control group (p value <0.0001). The VAS score at 3 months was significantly lower in voriconazole group 13.9 (9.3) mm as compared to MT alone group 22.3 (11.5) mm, p value of 0.003. Bronchoscopic instillation of voriconazole was also associated with reduction in cough severity and size of the aspergilloma; however, there was no benefit of this therapy in terms of requirement of hospitalization and BAE.

CONCLUSIONS

Our study shows that for nonoperable aspergilloma, bronchoscopic instillation of voriconazole is associated with reduction in the severity of hemoptysis. This therapy should be evaluated in large multi-center trials.

Aspergilloma complicating previous COVID-19 pneumonitis - a case report

Aspergillomas are found in pre-existing cavities in pulmonary parenchyma. To the best of our knowledge, aspergilloma has not previously been reported in COVID-19-associated pulmonary architecture distortion combined with barotrauma from invasive mechanical ventilation therapy. We present a case of a 67-year-old woman, who suffered from severe COVID-19 in the summer of 2020 with no suspicion of infection with Aspergillus in the acute phase. Ten months after discharge from her COVID-related admission, she developed bilateral aspergillomas diagnosed by image diagnostics, bronchoscopy, and blood samples, and she now receives antifungal therapy. We would like to raise awareness on aspergilloma in post-COVID-19 patients, since it is an expected long-term complication to COVID-19 patients with pulmonary architectural distortion.

Efficacy of 12-months oral itraconazole versus 6-months oral itraconazole to prevent relapses of chronic pulmonary aspergillosis: an open-label, randomised controlled trial in India

BACKGROUND

Chronic pulmonary aspergillosis has a 5-year mortality of 50-80% globally, and the optimal duration of treatment for chronic pulmonary aspergillosis remains unclear. We aimed to compare the effect of 6-months of oral itraconazole with 12-months of oral itraconazole on chronic pulmonary aspergillosis clinical outcomes.

METHODS

In this single-centre, open-label, randomised controlled trial conducted in one chest clinic in Chandigarh, India, we screened consecutive patients with chronic pulmonary aspergillosis who were naive to antifungal treatment and randomised eligible patients, using block randomisation, to receive a starting dose of 400 mg/day of oral itraconazole for either 6 months or 12 months. There was no masking of participants or investigators. We excluded patients who were unable to provide informed consent; had an intake of any antifungal drugs for more than 3 weeks in the preceding 6 months; had active Mycobacterium tuberculosis or non-tuberculous mycobacterial pulmonary disease; and had allergic, subacute, or invasive forms of aspergillosis. The primary outcome was the proportion of patients having relapse 2 years after treatment initiation. We performed an intention-to-treat analysis for all outcomes. The study is registered with ClinicalTrials.gov, NCT03920527.

FINDINGS

We recruited participants between July 1, 2019, and Aug 31, 2021. We screened 250 patients, of which 164 were included in the trial. 81 patients were randomised to the 6-month group and 83 patients were randomised to the 12-month group. The study population was 78 (48%) women and 86 (52%) men, and the mean age of participants was 44·3 (SD 13·3) years. The proportion of patients experiencing relapse was significantly lower in the 12-month group, 31 (38%) had a relapse in the 6-month group compared with 8 (10%) in the 12-month group, with an absolute risk reduction of 0.29 [95% CI 0·16-0·40]. The mean time to first relapse was 23 months in the 12-month group, which is significantly longer than the mean of 18 months in the 6-month group (p<0.0001). There were 16 deaths in total, eight in each group. Ten (12%) of 81 patients in the 6-months group and 18 (22%) of 83 patients in the 12-months group had adverse effects, with none requiring treatment modification. Nausea and anorexia were the most common adverse events in both groups.

INTERPRETATION

Treatment of chronic pulmonary aspergillosis with 12 months of oral itraconazole was superior to 6 months of oral itraconazole in reducing relapses at 2 years. Itraconazole should be given for at least 12 months for treating chronic pulmonary aspergillosis.

FUNDING

None.

Anti-Inflammatory and/or Anti-Fibrotic Treatment of MPO-ANCA-Positive Interstitial Lung Disease: A Short Review

The presence of a lung lesion is common in microscopic polyangiitis (MPA), and interstitial lung disease (ILD) can lead to a poor prognosis. Although myeloperoxidase antineutrophil cytoplasmic antibodies (MPO-ANCA) are often present in patients with MPA, patients with ILD and MPO-ANCA positivity but without other manifestations of systemic vasculitis have also been reported. Therefore, the possible association between MPO-ANCA, MPA, and idiopathic ILD remains unclear. This problematic matter has influenced the treatment strategy of MPO-ANCA-positive ILD patients without systemic vasculitis. Clinicians should undertake treatment with careful consideration of the four major causes of death in MPO-ANCA-positive ILD: acute exacerbation of ILD, progressive lung fibrosis, infectious comorbidities, and diffuse alveolar hemorrhage. Further, clinicians need to carefully judge whether inflammation or fibrosis is the dominant condition with reference to the patient’s clinical domain and radiopathological lung features. Recently, anti-fibrotic agents such as nintedanib and pirfenidone were shown to be effective in treating various etiologies associated with ILD and have thus led to the widening of treatment options. In this review, the clinical characteristics, radiopathology, prognosis, and therapeutic options in patients with MPO-ANCA-positive ILD are summarized using limited information from previous studies.

Prevalence of chronic pulmonary aspergillosis and the antifungal drug resistance of

The aim of our study was to determine the prevalence of chronic pulmonary aspergillosis in pulmonary tuberculosis patients and the antifungal resistance of Aspergillus spp. isolates in Uzbekistan. Chronic pulmonary aspergillosis was detected in 11.4% and 20.0% of smear-positive and smear-negative pulmonary tuberculosis patients, respectively.

Aspergillus pleural empyema in a chronic smoker - A case report and review of literature

Aspergillus species are ubiquitous saprophytic fungi that are present in the air, water, soil, and decaying vegetables. Clinical features of Aspergillus infection largely depend on the interplay between the fungi and the host immune status. We present a case of a chronic smoker with shortness of breath who was found to have diffuse bronchiectatic changes and empyema of the right lung. Emphysema was also noticed in the left lung. Rare Aspergillus fumigatus was identified in the pleural fluid, while the acid-fast stain and bacterial cultures were negative. The patient's serum Aspergillus fumigatus IgG antibody and galactomannan antigen were negative; however, the pleural galactomannan antigen was elevated. He was treated with video-assisted thoracoscopic surgery (VATS) and partial decortication of the right lung, along with intravenous voriconazole. Despite aggressive therapeutic measures, he died after a prolonged hospital stay. Aspergillus pleural empyema is rare but can be fatal; however, it is not included in the classification for pulmonary aspergillosis. Clinicians should be vigilant to evaluate for fungal empyema in patients with chronic obstructive pulmonary diseases, even without profound immunosuppression.

Cytomegalovirus viral interleukin-10 (cmvIL-10) in patients with Aspergillus infection and effects on clinical outcome

BACKGROUND

Human cytomegalovirus (CMV) is associated with aspergillosis, but the simultaneous presence of cytomegalovirus viral interleukin-10 (cmvIL-10) and aspergillosis has never been investigated. CmvIL-10 is produced by CMV-infected cells and acts as an immune modulator during CMV infection. The aim of this study was to evaluate cmvIL-10 levels in peripheral blood and its influence on the clinical outcomes of Aspergillus infection.

METHODS

Patients who visited or were admitted to the hospital with suspected Aspergillus infection, including invasive aspergillosis (IA) and chronic pulmonary aspergillosis (CPA), were prospectively enrolled. The cmvIL-10, human IL-10 (hIL-10), IL-1B, IL-6, IL-8, IFN-γ, and TNF-α levels in peripheral blood were measured.

RESULTS

Patients with Aspergillus infection had a higher level of cmvIL-10 than the control group (158±305 vs. 27.9±30.4 pg/mL, p<0.05). The level of cmvIL-10 was not correlated with CMV viremia or end-organ disease. The cmvIL-10 but not hIL-10 level was positively correlated with the IFN-γ level (p<0.05) and marginally negatively correlated with IL-1B and IL-8 levels (p<0.1). In patients with CPA, a high level of cmvIL-10 (≥100 pg/mL) was a poor prognostic factor for long-term survival (p<0.05). In contrast, CMV viremia or end-organ disease was associated with poor survival in patients with IA (p=0.05).

CONCLUSIONS

Aspergillus infection was associated with CMV coinfection with cmvIL-10 in blood. A cmvIL-10 concentration ≥100 pg/mL was a predictor for unfavourable outcome in CPA patients.

Prevalence of chronic pulmonary aspergillosis regarding time of tuberculosis diagnosis in Brazil

BACKGROUND

Data on the prevalence of chronic pulmonary aspergillosis (CPA) in patients with active or cured tuberculosis (TB) are scarce, mainly due to diagnostic difficulties. The diagnosis of CPA is based on pulmonary symptoms and chest computed tomography (CT) scans and is considered confirmed when there is microbiological or serological evidence of Aspergillus spp.

INFECTION

OBJECTIVES

To estimate the prevalence of CPA in patients treated or undergoing treatment for PTB, seen in two referral hospitals in Mato Grosso do Sul, Brazil.

PATIENTS AND METHODS

A total of 193 consecutive patients who were treated or previously treated for pulmonary tuberculosis underwent prospective evaluation: a) clinical evaluation; b) chest CT scan; c) sputum examination-culture for fungi and smears for direct mycology; d) detection of anti-Aspergillus fumigatus antibodies using an enzyme-linked immunosorbent assay Platelia® test; and e) anti-Aspergillus spp. antibodies were assessed via a DID test.

RESULTS

The global prevalence of CPA was 10.9% (95% confidence interval, 7.2-16.1%), but it increased with the time of TB diagnosis. The variables independently associated with CPA were previous pulmonary tuberculosis over 4 years ago and hemoptysis. Cavities, pleural thickening, and the presence of a fungal ball were the most frequent tomographic findings in patients with CPA.

CONCLUSIONS

The high prevalence observed and its increase over time suggest the need for continuous surveillance of CPA in patients with active or previous pulmonary tuberculosis and throughout life, with clinical, tomographic, and serological evaluations (ELISA) for a timely diagnosis and a better prognosis.

COVID‐19 complicated with chronic necrotizing pulmonary aspergillosis and aspergilloma progressing to fibrosing aspergillosis: A case report

Aspergillosis superinfections have been reported as acute complications of COVID‐19. We report a rare case of combined chronic necrotizing pulmonary aspergillosis, aspergilloma, and fibrosing aspergillosis in a 31‐year‐old woman with a history of COVID‐19. Chest scan remains an important imaging method assisting in the diagnosis and management of post‐COVID‐19 patients.

Value of CT Radiomics Combined with Clinical Features in the Diagnosis of Allergic Bronchopulmonary Aspergillosis

Objective

Early diagnosis of allergic bronchopulmonary aspergillosis (ABPA) and targeted treatment can block the process of the disease. This study explores the diagnostic value of CT radiomics combined with clinical features in allergic ABPA.

Methods

A total of 40 patients with ABPA were studied retrospectively, divided into training set (n = 28) and test set (n = 12). Based on CT imaging, the radiomics features are extracted and combined with clinical features to build a diagnostic model. The diagnosis model was based on support vector machine algorithm. The receiver operating characteristic curve (ROC) and area under the curve (AUC) were used to evaluate the diagnostic efficiency of the model.

Results

There was no significant difference in general information and clinical data between the training and test sets (P > 0.05). The AUC of the training set and the test set is 0.896 (95% CI: 0.836-0.963) and 0.886 (95% CI: 0.821-0.952), respectively.

Conclusion

Based on the CT radiomics model combined with clinical data, it has high efficiency in the diagnosis of ABPA.

Voriconazole Induced Cutaneous Squamous Cell Carcinoma in an Immunocompetent Patient

Voriconazole therapy can be associated with hair loss, vision changes, and skin phototoxicity, but rarely is it associated with the development of skin cancer. We present a case of an immunocompetent 42-year-old Caucasian male with a past medical history significant for chronic pulmonary aspergillosis (CPA) and prior cutaneous squamous cell carcinoma (cSCC) of the left hand who arrived at our clinic for evaluation of an enlarging, non-tender left preauricular mass over the past six months. He had diffuse actinic changes and appeared older relative to his age. He had a fair complexion but was compliant with sun protection measures and minimized unnecessary ultraviolet (UV) light exposure. His left-sided facial mass was excised, and the final pathology was consistent with cSCC. His only home medication was oral voriconazole 200 mg once daily for six years for pulmonary aspergillosis. He was negative for human immunodeficiency virus (HIV) and had no history of prior transplant operations. This case highlights the importance of recognizing voriconazole as an independent risk factor in the development of cSCC, especially in patients on chronic therapy for aspergillosis.

Serum Cytokines Usefulness for Understanding the Pathology in Allergic Bronchopulmonary Aspergillosis and Chronic Pulmonary Aspergillosis

Allergic bronchopulmonary aspergillosis (ABPA) and chronic pulmonary aspergillosis (CPA) are important fungal infections caused by Aspergillus species. An overlap of ABPA and CPA has been reported; therefore, it is critical to determine whether the main pathology is ABPA or CPA and whether antifungals are required. In this study, we investigated whether the serum cytokine profile is useful for understanding the pathology and for differentiating between these diseases. We compared the various serum cytokine levels among healthy subjects and patients diagnosed with asthma, ABPA, or CPA at Nagasaki University Hospital between January 2003 and December 2018. In total, 14 healthy subjects, 19 patients with asthma, 11 with ABPA, and 10 with CPA were enrolled. Interleukin (IL) -5 levels were significantly higher in patients with ABPA than in those with CPA, and IL-33 and tumor necrosis factor (TNF) levels were significantly higher in patients with CPA than in those with asthma (p < 0.05, Dunn’s multiple comparison test). The sensitivity and specificity of the IL-10/IL-5 ratio (cutoff index 2.47) for diagnosing CPA were 70% and 100%, respectively. The serum cytokine profile is useful in understanding the pathology of ABPA and CPA, and the IL-10/IL-5 ratio may be a novel supplemental biomarker for indicating the pathology of CPA.

Chronic pulmonary aspergillosis in patients with active pulmonary tuberculosis with persisting symptoms in Uganda

BACKGROUND

The occurrence of chronic pulmonary aspergillosis (CPA) among drug sensitive pulmonary tuberculosis (PTB) patients on optimal therapy with persistent symptoms was investigated.

METHODS

We consecutively enrolled participants with PTB with persistent pulmonary symptoms after 2 months of anti-TB treatment at Mulago Hospital, Kampala, Uganda between July 2020, and June 2021. CPA was defined as a positive Aspergillus-specific IgG/IgM immunochromatographic test (ICT), a cavity with or without a fungal ball on chest x-ray (CXR), and compatible symptoms >3 months.

RESULTS

We enrolled 162 participants (median age 30 years; IQR: 25 - 40), 97 (59.9%) were male, 48 (29.6%) were HIV-infected, and 15 (9.3%) had prior PTB. Thirty-eight (23.4%) sputum samples grew A. niger and 13 (8.0%) A. fumigatus species complexes. Six (3.7%) participants had intra-cavitary fungal balls, and 52 (32.1%) had cavities. Overall, 32 (19.8%) participants had CPA. CPA was associated with prior PTB (adjusted odds ratio (aOR): 6.61, 95% CI: 1.85 - 23.9, p=0.004), and far advanced CXR changes (aOR: 4.26, 95%CI: 1.72 - 10.52, p=0.002). The Aspergillus IgG/IgM ICT was positive in 10 (31.3%) participants with CPA.

CONCLUSIONS

CPA may cause persistent respiratory symptoms in up to one-fifth of patients after intensive treatment for PTB. The Aspergillus IgG/IgM ICT positivity rate was very low and may not be used alone for the diagnosis of CPA in Uganda.

Efficacy of LD Bio Aspergillus ICT Lateral Flow Assay for Serodiagnosis of Chronic Pulmonary Aspergillosis

Background: The diagnosis of CPA relies on the detection of the IgG Aspergillus antibody, which is not freely available, especially in resource-poor settings. Point-of-care tests like LDBio Aspergillus ICT lateral flow assay, evaluated in only a few studies, have shown promising results for the diagnosis of CPA. However, no study has compared the diagnostic performances of LDBio LFA in setting of tuberculosis endemic countries and have compared it with that of IgG Aspergillus. Objectives: This study aimed to evaluate the diagnostic performances of LDBio LFA in CPA and compare it with existing the diagnostic algorithm utilising ImmunoCAP IgG Aspergillus. Methods: Serial patients presenting with respiratory symptoms (cough, haemoptysis, fever, etc.) for >4 weeks were screened for eligibility. Relevant investigations, including direct microscopy and culture of respiratory secretions, IgG Aspergillus, chest imaging, etc., were done according to existing algorithm. Serums of all patients were tested by LDBio LFA and IgG Aspergillus (ImmunoCAP Asp IgG) and their diagnostic performances were compared. Results: A total of 174 patients were included in the study with ~66.7% patients having past history of tuberculosis. A diagnosis of CPA was made in 74 (42.5%) of patients. The estimated sensitivity and specificity of LDBio LFA was 67.6% (95% CI: 55.7−78%) and 81% (95% CI: 71.9−88.2%), respectively, which increased to 73.3% (95% CI: 60.3−83.9%) and 83.9% (95% CI: 71.7−92.4%), respectively, in patients with a past history of tuberculosis. The sensitivity and specificity of IgG Aspergillus was 82.4% (95% CI: 71.8−90.3%) and 82% (95% CI: 73.1−89%); 86.7% (95% CI: 75.4−94.1%) and 80.4% (95% CI: 67.6−89.8%), in the whole group and those with past history of tuberculosis, respectively. Conclusions: LDBio LFA is a point-of-care test with reasonable sensitivity and specificity. However, further tests may have to be done to rule-in or rule-out the diagnosis of CPA in the appropriate setting.

Co-existing active pulmonary tuberculosis with aspergilloma in a diabetic patient: A rare case report

Pulmonary aspergilloma is commonly associated with tuberculosis. Pulmonary aspergilloma is found in residual tuberculosis cavities and potential for other pathogens’ infections due to its sufficient oxygen and necrotizing tissue. A 48-year-old woman came with shortness of breath and cough for 7 months. She was diagnosed with pulmonary tuberculosis 9 months ago and was still under anti-tuberculosis drug therapy. She also suffered from type II diabetes mellitus. Chest examination showed vesicular sound decreased in third to fourth left intercostal spaces. A chest x-ray revealed a thick-walled cavity with the air-crescent sign in the left upper lobe lung leads to aspergilloma and active pulmonary tuberculosis. This finding was confirmed by the contrast-enhanced CT scan of the chest and continued to lobectomy. Histological examination confirmed the presence of a granuloma formation, necrosis, hyphae structure with the conclusion of Aspergillus sp. infection.

Aspergillosis: An Unwanted Tenant of Lung Cavity in an Immunocompromised Host

Immunocompromised status predisposes an individual to infection from bacteria, fungi, and viruses that are otherwise uncommon. The presence of carcinoma and the use of chemotherapy weakens one’s immune system and leads to opportunistic infections of many kinds. Aspergilloma is a fungal ball that grows inside a primary cavitary lesion within the pulmonary parenchyma. Generally, immunocompromised individuals have severe and invasive infections from Aspergillus. Here, we present a case report of a female with breast carcinoma undergoing chemotherapy who previously had a lung abscess with Klebsiella. During her subsequent presentation, she was detected to have aspergilloma along with multi-drug-resistant organisms in the lung abscess along with metastasis of breast carcinoma and lung squamous cell carcinoma encapsulating the fungal ball.

Cavitating pulmonary lung lesions with more than one microbiological aetiology

Non-tuberculous mycobacteria (NTM) are one of the predominant microbes observed in immunocompromised patients with structural lung disease. Especially in immunocompromised patients, the treating physician needs to be aware of concurrent lung infections with opportunistic pathogens. In this case report we present a man in his 60s with severe chronic obstructive pulmonary disease (COPD) and bullous emphysema, who was diagnosed with Mycobacterium europaeum but with persistent clinical deterioration despite relevant treatment for NTM. A subsequent bronchoalveolar lavage (BAL) revealed elevated Aspergillus galactomannan antigen which, when seen in relation to imaging-findings of cavitating opacities with aggravating surrounding consolidation, raised suspicion of concurrent subacute invasive aspergillosis. Antifungal treatment was initiated but due to intolerable side effects was discontinued after only a few weeks. This case highlights the importance of concurrent testing for pulmonary aspergillosis in NTM patients and vice versa before treatment initiation and if the disease and symptoms are progressing despite relevant treatment.

SARS-CoV-2 Associated Immune Dysregulation and COVID-Associated Pulmonary Aspergilliosis (CAPA): A Cautionary Tale

As the global SARS-CoV-2 pandemic continues to plague healthcare systems, it has become clear that opportunistic pathogens cause a considerable proportion of SARS-CoV-2-associated mortality and morbidity cases. Of these, Covid-Associated Pulmonary Aspergilliosis (CAPA) is a major concern with evidence that it occurs in the absence of traditional risk factors such as neutropenia and is diagnostically challenging for the attending physician. In this review, we focus on the immunopathology of SARS-CoV-2 and how this potentiates CAPA through dysregulation of local and systemic immunity as well as the unintended consequences of approved COVID treatments including corticosteroids and IL-6 inhibitors. Finally, we will consider how knowledge of the above may aid in the diagnosis of CAPA using current diagnostics and what treatment should be instituted in probable and confirmed cases.

Incidence of Chronic Pulmonary Aspergillosis in Patients with Suspected or Confirmed NTM and TB—A Population-Based Retrospective Cohort Study

Chronic pulmonary aspergillosis (CPA) is a severe and underdiagnosed pulmonary fungal infection with a significant overlap in symptoms and imaging findings of mycobacterium tuberculosis (TB) and non-tuberculous mycobacterium (NTM). Infection with TB or NTM is a predisposing underlying condition for CPA in approximately one-third of patients. A previously published study from Uganda showed increased incidence and complication rate of CPA with respect to pre-existing radiographic cavitation in a post-treatment TB population. The aim of this study was to investigate the incidence of CPA in a low-endemic population of confirmed or suspected TB and NTM patients. We manually reviewed 172 patients referred on suspicion or for treatment of TB or NTM at the Department of Respiratory Medicine, Odense University Hospital during the period of 1 January 2018 to 31 December 2020. We found no CPA amongst TB patients as opposed to an incidence of 8.2% (n = 4) in NTM-infected patients. We identified possible investigatory differences in Aspergillus blood sample screening protocols depending on NTM or TB, initiated at the Department of Respiratory Medicine at Odense University Hospital. A focused screening and investigatory protocol in NTM patients with persisting or developing symptoms is warranted in relation to suspected CPA.

Prevalence of Chronic Pulmonary Aspergillosis in Patients Suspected of Chest Malignancy

Chronic pulmonary aspergillosis (CPA) is a potentially life-threatening fungal lung infection, and recent research suggests CPA to be more common than previously considered. Although CPA mimics other lung diseases including pulmonary cancer, awareness of this disease entity is still sparse. This study aimed to investigate the prevalence of CPA in a population of patients under suspicion of having lung cancer. We conducted a retrospective cohort study of 1200 patients and manually collected individual health record data from previous cancer examinations, with retrospective CPA status assessment using international criteria. Among 992 included patients, 16 (1.6%) fulfilled diagnostic criteria for CPA retrospectively, of whom 15 were undiscovered at initial lung cancer examination. The prevalence of CPA in this study population was 50 times higher than the reported prevalence of the overall European population. Our findings indicate that CPA is often missed in patients suspected of malignancy in the chest. Therefore, CPA should be kept in mind as a significant differential diagnosis.

Clinical Features, Diagnostic Test Performance, and Prognosis in Different Subtypes of Chronic Pulmonary Aspergillosis

Objective

The aim of this study was to describe clinical features in different subtypes of chronic pulmonary aspergillosis (CPA)-simple aspergilloma (SA), chronic cavitary pulmonary aspergillosis (CCPA), chronic fibrosing pulmonary aspergillosis (CFPA), aspergillus nodule (AN), and subacute invasive aspergillosis (SAIA), respectively, and identify long-term prognosis of CPA.

Methods

We reviewed patients diagnosed with different subtypes of CPA from 2002 to 2020 at Nanjing Jinling Hospital, China. We analyzed the clinical and survival information of five different subgroups. A Cox regression model was used to explore proper antifungal duration and long-term survival factors of CCPA and SAIA.

Results

A total of 147 patients with CPA were included, consisting of 11 SA, 48 CCPA, 5 CFPA, 12 AN, and 71 SAIA. The most common underlying pulmonary disease was pulmonary tuberculosis (n = 49, 33%), followed by bronchiectasis (n = 46, 31.3%) and chronic obstructive pulmonary disease (COPD) or emphysema (n = 45, 30.6%), while in SAIA and CFPA groups, the most common was COPD or emphysema (45.1 and 100%). Cough (85%), expectoration (70.7%), hemoptysis (54.4%), and fever (29.9%) were common symptoms, especially in CCPA, CFPA, and SAIA groups. The common imaging manifestations included cavitation (n = 94, 63.9%), fungal ball (n = 54, 36.7%), pleural thickening (n = 47, 32.0%), and bronchiectasis (n = 46, 31.3%). SAIA and CFPA groups had a lower value of hemoglobin (HB) and serum albumin (ALB) with higher C-reactive protein and erythrocyte sedimentation rate. The positive rate of sputum culture, serum galactomannan (GM), and bronchoalveolar lavage fluid GM was 32.7% (36/110), 18.4% (18/98), and 48.7% (19/39), respectively. There were 64.6% (31/48) patients with CCPA and 25.4% (18/71) patients with SAIA who received surgery and the 5-year cumulative survival rate was 92.1 and 66.6%, respectively. SAIA, old age, male, low body mass index (BMI), COPD or emphysema, multiple distribution, low serum ALB, and positive sputum culture were adverse prognosis factors for SAIA and CCPA group, and BMI ≤ 20.0 kg/m² was independently associated with increased mortality (hazard ratio (HR) 5.311, 95% CI 1.405–20.068, p = 0.014). Multivariable Cox regression indicated that surgery (HR 0.093, 95% CI 0.011–0.814, p = 0.032) and antifungal duration >6 months (HR 0.204, 95% CI 0.060–0.696 p = 0.011) were related to improved survival.

Conclusion

The clinical features and laboratory test performance are different among SA, CCPA, CFPA, AN, and SAIA. Low BMI was an independent risk factor for survival. Selective surgery and antifungal duration over 6 months were associated with improved survival.

Azole Resistance in Aspergillus fumigatus. The first 2-year's Data from the Danish National Surveillance Study, 2018-2020

BACKGROUND

Azole resistance complicates treatment of patients with invasive aspergillosis with an increased mortality. Azole resistance in Aspergillus fumigatus is a growing problem and associated with human and environmental azole use. Denmark has a considerable and highly efficient agricultural sector. Following reports on environmental azole resistance in A. fumigatus from Danish patients the ministry of health requested a prospective national surveillance of azole resistant A. fumigatus and particularly that of environmental origin.

OBJECTIVES

To present the data from the first two years of the surveillance programme.

METHODS

Unique isolates regarded as clinically relevant and any A. fumigatus isolated on a preferred weekday (background samples) were included. EUCAST susceptibility testing was performed and azole-resistant isolates underwent cyp51A gene sequencing.

RESULTS

The azole resistance prevalence was 6.1% (66/1083) at patient level. The TR₃₄ /L98H prevalence was 3.6% (39/1083) and included the variants TR₃₄ /L98H, TR₃₄ ³ /L98H and TR₃₄ /L98H/S297T/F495I. Resistance caused by other Cyp51A variants accounted for 1.3% (14/1083) and included G54R, P216S, F219L, G54W, M220I, M220K, M220R, G432S, G448S and Y121F alterations. Non-Cyp51A mediated resistance accounted for 1.2% (13/1083). Proportionally, TR₃₄ /L98H, other Cyp51A variants and non-Cyp51A mediated resistance accounted for 59.1% (39/66), 21.2% (14/66) and 19.7% (13/66), respectively, of all resistance. Azole resistance was detected in all five Regions in Denmark, and TR₃₄ /L98H specifically, in four of five regions during the surveillance period.

CONCLUSION

The azole resistance prevalence does not lead to a change in the initial treatment of aspergillosis at this point, but causes concern and leads to therapeutic challenges in the affected patients.

Case Report: Chronic Pulmonary Aspergillosis-An Unusual Long-Term Complication of Lung Cancer Treatment

Background: Chronic pulmonary aspergillosis (CPA) is a rare complication of radiochemotherapy for lung cancer. It may develop months or years after radical treatment. The diagnosis of CPA is challenging and complex. Not only fungal infection but also cancer relapse always have to be taken under consideration. Antifungal therapy is the base treatment, especially in the case when a surgical procedure is not possible. Standard treatment for at least 6 months is recommended but the optimal duration of the antifungal therapy is unknown. We present the clinical case of CPA, in which we had to perform multidirectional diagnostic tests to confirm the diagnosis and modified treatment due to the recurrence of the disease.

Case Presentation: We report a patient who developed CPA three and a half years after concurrent radiochemotherapy for locally advanced non-small-cell lung cancer. Non-specific symptoms were the cause of delayed diagnosis of fungal infection. Samples collected during bronchoscopy allowed to exclude the recurrence of lung cancer and establish the diagnosis of CPA. The patient was treated with itraconazole for 6 months. A few months later, controlled chest CT scans revealed the progression of CPA. Initially, retreatment with itraconazole was implemented. Due to the progression of fungal infection, voriconazole was used in the second line of treatment. Unfortunately, this therapy was complicated by the side effects and deterioration of the patient's condition. The reintroduction of itraconazole resulted in clinical and radiological improvement. Treatment is scheduled for at least 12 months.

Conclusion: Chronic pulmonary aspergillosis (CPA) was the cause of clinical deterioration and radiological progression in a patient after the radical treatment of lung cancer. In the described case, the diagnosis of CPA was delayed because of the suspicion of the recurrence of lung cancer. As the surgery was not possible, antifungal therapy with itraconazole was implemented and the proper dosage and duration led to significant clinical improvement.

Serological Changes in Anti-Aspergillus IgG Antibody and Development of Chronic Pulmonary Aspergillosis in Patients Treated for Pulmonary Tuberculosis

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.

Chronic Pulmonary Aspergillosis: Burden, Clinical Characteristics and Treatment Outcomes at a Large Australian Tertiary Hospital

Chronic pulmonary aspergillosis (CPA) is a fungal lung infection associated with high morbidity and mortality. Yet, it remains under-recognized worldwide, with few Australian clinical data available. This retrospective study aimed to investigate CPA at a major tertiary referral hospital in Sydney. We identified patients having International Classification of Diseases (ICD-10) codes for “aspergillosis” and/or positive respiratory microbiology samples for Aspergillus species from January 2012–December 2018 at Westmead Hospital. Eligible cases were classified using European Respiratory Society 2016 CPA guidelines. We diagnosed 28 CPA patients: median age 60 years (IQR: 57–66), with 17 (60.7%) being males. Most had chronic cavitary pulmonary aspergillosis phenotype (n = 17, 60.7%). Twenty-three patients had outcomes data returned. Nineteen (82.6%) received antifungal therapy (median duration: 10.5 months (IQR: 6.5–20.7)). Eight (34.7%) patients received <6 months of antifungals, including three (38%) deaths. Two (13%) patients receiving ≥6 months of antifungals died. Chronic obstructive pulmonary disease (COPD) (n = 9, 32.1%) was the leading predisposing factor for CPA in our cohort. This contrasts with the global picture, where prior tuberculosis generally predominates, but is similar to findings from other high-income countries. Nevertheless, further larger-scale studies are required to determine whether these results are generalizable to the wider Australian population.

Outcomes of surgery for different types of chronic pulmonary aspergillosis: results from a single-center, retrospective cohort study

Background

The reported experience of surgical treatment for chronic pulmonary aspergillosis (CPA) mainly focused on simple aspergilloma (SA), few about other types of CPA. The present study aims to evaluate the outcomes of surgical treatment for different types of CPA.

Methods

We performed a retrospective analysis of 85 patients with CPA who underwent surgery from 2014 to 2020 at Shandong Provincial Chest Hospital. The patients were divided into four types, including SA, chronic cavitary pulmonary aspergillosis (CCPA), chronic fibrosing pulmonary aspergillosis (CFPA), aspergillus nodule (AN). We collected and analyzed the preoperative, perioperative, and postoperative data to evaluate the outcomes of surgical treatment of different types of CPA.

Results

The four groups had similar age (p = 0.22), symptoms (p = 0.36), lesion location (p = 0.09), VATS rate (p = 0.08), recurrence rate (p = 0.95), and had significant difference in surgical procedures (p < 0.01), time of surgery (p < 0.01), intraoperative blood loss (p < 0.01), postoperative complication (p = 0.01). CFPA (P = 0.01), longer surgical time (P = 0.001), and more intraoperative blood loss (P = 0.004) were risk factors of postoperative complication, more intraoperative blood loss (> 400 ml) was the independent risk factor (OR 13.5, 95% CI 1.6–112.1, P = 0.02). 6 patients relapsed after surgery with a recurrence rate of 7.1%. The mean time to relapse was 14.8 months (2–30 months) after surgery. Relapse occurred in 2 SA patients, 3 CCPA, and 1 CFPA, respectively, while none of the AN patients relapsed. No risk factor for recurrence was found.

Conclusions

Surgical resection seems safe and effective in the treatment of SA, AN, CCPA with a low complication and recurrence rate, while surgery for CFPA should be limited to selected patients because of its higher complication rate.

Impact of emphysema on the prognosis of Mycobacterium avium complex pulmonary disease

BACKGROUND

Chronic obstructive pulmonary disease (COPD) is a major comorbid disease of Mycobacterium avium complex pulmonary disease (MAC-PD). Emphysema is one of the main pathological findings in COPD, a risk factor for chronic pulmonary aspergillosis (CPA), and is associated with poor prognosis. We aimed to clarify the effect of emphysema on mortality in MAC-PD.

METHODS

We retrospectively analyzed 203 patients with MAC-PD at The Jikei Daisan Hospital between January 2014 and December 2018. We investigated the mortality and CPA development rates after MAC-PD diagnosis in patients with or without emphysema.

RESULTS

Multivariate Cox proportional hazards regression analysis showed the following negative prognostic factors in patients with MAC-PD: emphysema (hazard ratio [HR]: 11.46; 95% confidence interval [CI]: 1.30-100.90; P = 0.028); cavities (HR: 3.12; 95% CI: 1.22-7.94; P = 0.017); and low body mass index (<18.5 kg/m²) (HR: 4.62; 95% CI: 1.63-13.11; P = 0.004). The mortality and occurrence of CPA were higher in MAC-PD patients with than without emphysema (log-rank test, P < 0.0001 and P < 0.0001).

CONCLUSION

Our study findings showed that emphysema detected by computed tomography was associated with an increased risk of CPA development and mortality in MAC-PD.

Chronic Pulmonary Aspergillosis and Type 2 Diabetes Mellitus Complicating Granulomatosis with Polyangiitis in an Adult Saudi Male: A Case Report

Background

Granulomatosis with polyangiitis (GPA) is an extremely rare autoimmune, necrotizing granulomatous disease of unknown etiology affecting small and medium-sized blood vessels. Chronic pulmonary aspergillosis (CPA) is a rare fungal infection with high morbidity and mortality that usually affects immunocompetent or mildly immunosuppressed patients with underlying respiratory disease. Antifungal agents (voriconazole, itraconazole) are the mainstay of therapy. Intravenous drug therapy (amphotericin B or an echinocandin), alone or in combination with azoles, is the last resort in special situations such as azole failure, resistance, or severe disease. Sometimes CPA and GPA coexist and are difficult to distinguish due to the nonspecific symptoms and similarity of clinical and radiological features, so a high degree of suspicion is required to make the correct diagnosis.

Case Presentation

We reported that a 28-year-old man from Saudi Arabia was diagnosed with GPA. The patient had been complaining of cough, fatigue, polyarthralgia and red eyes for 40 days before he was admitted to our hospital. The diagnosis of GPA was confirmed by clinical and radiological examinations and a pathological report of a lung biopsy, and he was treated with immunosuppressive drugs. The patient’s condition was complicated by chronic pulmonary aspergillosis and type 2 diabetes mellitus. Initial treatments included systemic glucocorticoids, methotrexate, followed by rituximab and voriconazole, finally intravenous cyclophosphamide and amphotericin B, with no complete remission. The thoracic surgical team postponed surgical debridement of the significant cavitary lung lesions until the active fungal infection could be brought under control.

Conclusion

The clinical and radiological features of GPA are similar to those of pulmonary tuberculosis, chronic pulmonary aspergillosis, and lung cancer. The lack of clear clinical symptoms of GPA requires a high degree of suspicion for early diagnosis. This case illustrates the dilemma of diagnosis and treatment of GPA and superimposed fungal infection. Secondary infection, particularly fungal infection, must be considered when GPA cannot be controlled with an immunosuppressant.

Chronic pulmonary aspergillosis in a patient with hyper-IgE syndrome

Hyperimmunoglobulin E (IgE) syndrome (HIES) is a rare disease with an unclear prognosis. We report a case of HIES comorbid with chronic pulmonary aspergillosis (CPA). A 19-year-old male was referred to our department with a medical history of bacterial pneumonia and skin infection. Laboratory data showed an elevated eosinophil count and serum IgE level. Chest computed tomography (CT) showed a pneumatocele and bronchiectasis. On the basis of the clinical and laboratory findings and genetic mutation analysis, we diagnosed him as having HIES. Fourteen months later, he complained of blood-tinged sputum and haemoptysis. Chest CT showed pneumatocele wall thickening, fungus ball and consolidation. Serum Aspergillus precipitating antibody and serum galactomannan Aspergillus antigen were positive, and Aspergillus fumigatus was detected in the sputum. We diagnosed CPA and treated him using antifungal agents and bronchial artery embolization. CPA is a complication that requires attention in patients with HIES.

Pulmonary aspergilloma coexisting with hamartoma in post pulmonary tuberculosis: A case report

Introduction

Aspergillosis is a fungal disease caused by the Aspergillus fumigatus. Until now, the management of aspergilloma is still controversial, and there is no consensus among experts. Hamartoma is a benign tumor that can be found in the lung. We report a case of pulmonary aspergilloma coincidentally with hamartoma in pulmonary tuberculosis (TB) patients. Aspergilloma and hamartoma diagnoses are challenging because of various clinical symptoms.

Case report

A 46 years old man came to emergency unit with complaints shortness of breath, cough, and chest tightness. He also has a red-black blood streak and terrible odor sputum. He had a history of two episodes of pulmonary TB. Holistic physical and additional examinations were done. Patient was diagnosed with aspergillosis infection in post pulmonary TB. The patient was then undergoing surgery. From the pathology of lung tissue, we found hamartoma features. Antifungal, antibiotic, and supported therapy were given, and his condition improved after a month of hospitalization.

Conclusion

Pulmonary aspergilloma and hamartoma coincidence are rare diseases. Aspergilloma diagnosis is made based on clinical symptoms, radiological, and serological examination. Pulmonary hamartoma is generally asymptomatic. In this case, hamartoma was incidentally found in pathology examination. Prompt and precise diagnosis with good therapeutic management yield favorable outcomes.
