Objectives: Chronic pulmonary aspergillosis (CPA) is a fungal lung infection characterised by the slowly progressing destruction of the lung parenchyma and has four main subtypes. The objective of this work was to evaluate the epidemiology of CPA in our area and evaluate the involvement of the different subtypes in mortality. Methods: This was a descriptive longitudinal retrospective study developed in three tertiary hospitals in Spain. Among all patients admitted with a pulmonary aspergillosis diagnosis, we selected those who fulfilled the criteria for chronic aspergillosis according to the criteria of Denning, excluding those with a haematological disorder. Results: Among 409 inpatients recorded as having a pulmonary aspergillosis infection, only 76 (18.5%) fulfilled the criteria for CPA, with an estimated incidence of 0.67 cases/100,000 inhabitants/year. The subtypes detected were subacute invasive aspergillosis (SAIA) in 33 (43.4%) patients, simple aspergilloma (SA) in 25 (32.9%) patients, cavitary chronic aspergillosis (CCPA) in 13 (17.1%) patients, and chronic fibrosis (CFPA) in five (6.5%) patients. The overall three-month mortality rate was 23%, which was higher in SAIA patients. The predictors of early mortality were age > 65 years (OR 3.0 CI 95 1.0–9.5 p = 0.043) and the SAIA subtype vs. other subtypes (OR 3.1 CI 95 1.0–9.5 p = 0.042). Conclusions: The incidence rate estimated was inferior to that previously reported. The three-month mortality in patients with CPA was high, with older age and the SAIA subtype being the variable independent predictors of a worse prognosis.

Chronic pulmonary aspergillosis (CPA) is estimated to affect 3 million people worldwide making it an under recognised, but significant health problem across the globe, conferring significant morbidity and mortality. With variable disease forms, high levels of associated respiratory co-morbidity, limited therapeutic options and prolonged treatment strategies, CPA is a challenging disease for both patients and healthcare professionals. CPA can mimic smear-negative tuberculosis (TB), pulmonary histoplasmosis or coccidioidomycosis. Cultures for Aspergillus are usually negative, however, the detection of Aspergillus IgG is a simple and sensitive test widely used in diagnosis. When a fungal ball/aspergilloma is visible radiologically, the diagnosis has been made late. Sometimes weight loss and fatigue are predominant symptoms; pyrexia is rare. Despite the efforts of the mycology community, and significant strides being taken in optimising the care of these patients, much remains to be learnt about this patient population, the disease itself and the best use of available therapies, with the development of new therapies being a key priority. Here, current knowledge and practices are reviewed, and areas of research priority highlighted.

Background: Chronic pulmonary aspergillosis (CPA) is a life-threatening sequel in patients with pulmonary tuberculosis (PTB). Aspergillus-specific IgG antibody is a useful diagnostic biomarker supporting CPA diagnosis, especially in countries with limited health recourses. Methods: We conducted a prospective pilot study to assess the seroprevalence of Aspergillus-specific IgG antibodies among 61 Mozambican tuberculosis patients before, during, and after the end of TB treatment. Aspergillus-specific IgG antibody levels were measured using the ImmunoCAP®. Results: In this study, 3 out of 21 HIV-negative PTB patients had a positive Aspergillus-specific IgG antibody level before, during, and after the end of TB treatment. Antibody levels were 41.1, 45.5, and 174 mg/L at end of treatment (EOT), respectively. Additionally, two HIV-negative PTB patients with negative Aspergillus-specific IgG antibody levels at baseline became seropositive at EOT (41.9 and 158 mg/L, respectively). Interestingly, none of the HIV-positive PTB patients (40/61) had a positive Aspergillus-specific IgG antibody level at any time, neither at baseline nor at EOT. Probable CPA was diagnosed in one HIV-negative patient (5%; 1/20). Conclusion: Seroprevalence of Aspergillus-specific IgG antibody may differ between HIV-negative and HIV-positive Mozambican PTB patients. Future studies evaluating post-tuberculosis lung disease should integrate CPA as a life-threatening sequel to PTB.

Azole resistance in Aspergillus fumigatus has emerged as a global health problem. Although the number of cases of azole-resistant aspergillosis is still limited, resistance mechanisms continue to emerge, thereby threatening the role of the azole class in the management of diseases caused by Aspergillus. The majority of cases of azole-resistant disease are due to resistant A. fumigatus originating from the environment. Patient management is difficult due to the absence of patient risk factors, delayed diagnosis, and limited treatment options, resulting in poor treatment outcome. International and collaborative efforts are required to understand how resistance develops in the environment to allow effective measures to be implemented aimed at retaining the use of azoles both for food production and human medicine.

Chronic pulmonary aspergillosis (CPA) complicates conditions including tuberculosis, chronic obstructive pulmonary disease and sarcoidosis, and is associated with high morbidity and mortality. Surgical cure should be considered where feasible; however, many patients are unsuitable for surgery due to extensive disease or poor respiratory function. Azoles are the only oral drug with anti-Aspergillus activity and itraconazole and voriconazole are considered as first-line drugs. A randomized controlled trial demonstrated improvement or stability in three-quarters of patients given 6 months of itraconazole, but a quarter relapsed on stopping therapy. Long-term treatment may therefore be required in some cases. Itraconazole, voriconazole and posaconazole require therapeutic drug monitoring. No published data are yet available for isavuconazole. Adverse drug effects of azoles are common, including peripheral neuropathy, heart failure, elevated liver enzymes, QTc prolongation and sun sensitivity. Many serious drug-drug interactions occur, including major interactions with rifamycins, simvastatin, warfarin, clopidogrel, immunosuppressant drugs like sirolimus. Furthermore, drug resistance occurs, including cross-resistance to all azoles, but the true prevalence is not yet determined. Intravenous therapy is possible with echinocandins or amphotericin B, but long-term use is challenging. Hemoptysis complicates CPA and can be fatal. Tranexamic acid should be given acutely to reduce bleeding. Bronchial artery embolization can stop acute bleeds. In some circumstances, emergency surgery may be necessary to resect the source of the bleed. Current CPA treatments can be beneficial but have many drawbacks. New oral anti-Aspergillus agents are needed, along with optimization of currently available treatments.

We evaluated the expression of biomarkers of innate and adaptive immune response in correlation with underlying conditions in 144 patients with chronic pulmonary aspergillosis (CPA). Patients with complete medical and radiological records, white cell counts, and a complete panel of CD3, CD4, CD8, CD19, and CD56 lymphocyte subsets were included. Eighty-four (58%) patients had lymphopenia. Six (4%) patients had lymphopenia in all five CD variables. There were 62 (43%) patients with low CD56 and 62 (43%) patients with low CD19. Ten (7%) patients had isolated CD19 lymphopenia, 18 (13%) had isolated CD56 lymphopenia, and 15 (10%) had combined CD19 and CD56 lymphopenia only. Forty-eight (33%) patients had low CD3 and 46 (32%) had low CD8 counts. Twenty-five (17%) patients had low CD4, 15 (10%) of whom had absolute CD4 counts <200/μL. Multivariable logistic regression showed associations between: low CD19 and pulmonary sarcoidosis (Odds Ratio (OR), 5.53; 95% Confidence Interval (CI), 1.43–21.33; p = 0.013), and emphysema (OR, 4.58; 95% CI; 1.36–15.38; p = 0.014), low CD56 and no bronchiectasis (OR, 0.27; 95% CI, 0.10–0.77; p = 0.014), low CD3 and both multicavitary CPA disease (OR, 2.95; 95% CI, 1.30–6.72; p = 0.010) and pulmonary sarcoidosis (OR, 4.94; 95% CI, 1.39–17.57; p = 0.014). Several subtle immune defects are found in CPA.

Aspergillosis is a fungal infection, caused by the mould Aspergillus, most commonly Aspergillus fumigatus species. Chronic pulmonary aspergillosis after SARS Cov-2 infection is a rare presentation that is commonly misdiagnosed. The prolonged corticosteroid and antibiotic application and the pro-inflammatory state in COVID-19 patients predisposes to Aspergillus infection and its chronification. Surgery plays a pivotal role in cases with unclear diagnosis, ineffective medical therapy or when complications develop. We present a case of a 73-year-old woman with chronic pulmonary aspergillosis, developed after COVID-19 pneumonia. A right lateral muscle-sparing thoracotomy, right upper lobectomy and atypical resection of the 9th and 10th segments were performed.

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. COPD is susceptible to aspergillus, and this review will summarise the diagnosis and treatment of IPA, CPA and aspergillus sensitisation in COPD patients.

Chronic pulmonary aspergillosis (CPA) is a progressive fungal disease that primarily affects individuals with preexisting lung conditions. The clinical presentation, radiological characteristics, and outcomes of CPA in people living with HIV (PLHIV) remain poorly understood. We conducted a retrospective study at Hospital das Clínicas, University of São Paulo, Brazil, reviewing medical records of CPA patients from January 2010 to November 2024. HIV-infected and HIV-negative CPA patients were compared in terms of clinical features, diagnostic findings, treatment strategies, and outcomes. CPA diagnosis was based on European Society for Clinical Microbiology and Infectious Diseases and European Respiratory Society criteria. A total of 96 CPA patients were included, of whom 8 (8%) were PLHIV. Compared to HIV-negative patients, PLHIV were younger (median age: 44 vs. 52 years, p  = 0.13) and more likely to have active pulmonary TB (38% vs. 4.5%, p  = 0.013). Itraconazole was the most used antifungal in both groups (57% vs. 79%, p  = 0.2). One-year mortality also did not differ significantly between PLHIV and HIV-negative patients (13% vs. 4%, p  = 0.3). Notably, 50% of PLHIV experienced clinical failure despite prolonged antifungal therapy and/or surgery. In conclusion, CPA in PLHIV is frequently associated with active TB and presents with a high rate of clinical failure despite treatment. Our findings highlight the need for optimized diagnostic and therapeutic strategies for CPA in this under-recognized population. Further prospective studies are warranted to better define prognostic factors and improve management approaches.

Background A clear cutoff value of galactomannan (GM) has not been established for chronic pulmonary aspergillosis (CPA) and is frequently extrapolated from invasive pulmonary aspergillosis. We performed a systematic review and meta-analysis to evaluate the diagnostic performance of serum and bronchoalveolar lavage (BAL) GM, and to propose a cutoff. Methods We extracted from the studies the cutoff of serum or/and BAL GM associated with true positives, false positives, true negatives, and false negatives. We performed a multi-cutoff model and a non-parametric random effect model. We estimated the optimal cutoff and the area under the curve (AUC) for GM in serum and BAL samples. Results Nine studies from 1999 to 2021 were included. Overall, the optimal cutoff of serum GM was 0.96 with a sensitivity of 0.29 (95%CI: 0.14–0.51); specificity of 0.88 (95%CI: 0.73–0.95); and AUC of 0.529 (with a CI: [0.415–0.682] [0.307–0.713]). The AUC for the non-parametric ROC model was 0.631. For BAL GM the cutoff was 0.67 with a sensitivity of 0.68 (95%CI: 0.51–0.82), specificity of 0.84 (95%CI: 0.70–0.92), and AUC of 0.814 (with a CI: [0.696–0.895] [0.733–0.881]). The AUC for the non-parametric model was 0.789. Conclusion The diagnosis of CPA requires the assessment of a combination of mycological and serological factors, as no single serum and/or BAL GM antigen test is adequate. BAL GM performed better than serum, with better sensitivity and excellent accuracy.
