Despite antifungal treatment, chronic pulmonary aspergillosis (CPA) is associated with substantial morbidity and mortality. We conducted a systematic review and meta-analysis to evaluate rates of mortality and its predictors in CPA. A systematic literature search was conducted across MEDLINE (PubMed), Scopus, Embase, and Web of Science to identify studies in English, reporting mortality in CPA, from database inception to Aug 15, 2023. We included clinical studies, observational studies, controlled trials, and abstracts. Case reports, animal studies, letters, news, and literature reviews were excluded. Authors of studies published since 2016 were also contacted to obtain anonymised individual patient data (IPD); for other studies, summary estimates were extracted. Subgroup analysis was done for differences in overall 1-year and 5-year mortality, data source, study design, risk of bias, country, Human Development Index, age groups, and the underlying lung disease. We used random-effects meta-analyses to estimate pooled mortality rates. Subgroup analyses and meta-regression were done to explore sources of heterogeneity. One-stage meta-analysis with a stratified Cox proportional hazards model was used to estimate the univariable and hazards for mortality, adjusting for age, sex, type of CPA, treatment, and underlying pulmonary comorbidities. This study was registered with PROSPERO (CRD42023453447). We included 79 studies involving 8778 patients in the overall pooled analysis and 15 studies involving 1859 patients in the IPD meta-analysis. Pooled mortality (from 70 studies) was estimated at 27% overall (95% CI 22-32; I² =95·4%), 15% at 1 year (11-19; I² =91·6%), and 32% at 5 years (25-39; I² =94·3%). Overall mortality in patients with CPA with pulmonary tuberculosis as the predominant predisposing condition was 25% (16-35; I² =87·5%; 20 studies) and with chronic obstructive pulmonary disease was 35% (22-49; I² =89·7%; 14 studies). Mortality in cohorts of patients who underwent surgical resection was low at 3% (2-4). In the multivariable analysis, among predisposing respiratory conditions, pulmonary tuberculosis history had the lowest mortality hazard (relative to an absence of the disease at baseline), whereas worse outcomes were seen with underlying malignancy; subacute invasive pulmonary aspergillosis and chronic cavitary pulmonary aspergillosis subtypes of CPA were also significantly associated with increased mortality relative to simple aspergilloma on multivariable analysis. Mortality hazard increased by 25% with each decade of age (adjusted hazard ratio 1·25 [95% CI 1·14-1·36], p<0·0001). CPA is associated with substantial mortality. Advancing age, CPA subtype, and underlying comorbidities are important predictors of mortality. Future studies should focus on identifying appropriate treatment strategies tailored to different risk groups. None.

Chronic pulmonary aspergillosis (CPA) is a challenging respiratory infection caused by the environmental fungus Aspergillus. CPA has a poor prognosis, with reported 1-year mortality rates ranging from 7% to 32% and 5-year mortality rates ranging from 38% to 52%. A comprehensive understanding of the pathogen, pathophysiology, risk factors, diagnosis, surgery, hemoptysis treatment, pharmacological therapy, and prognosis is essential to manage CPA effectively. In particular, Aspergillus drug resistance and cryptic species pose significant challenges. CPA lacks tissue invasion and has specific features such as aspergilloma. The most critical risk factor for the development of CPA is pulmonary cavitation. Diagnostic approaches vary by CPA subtype, with computed tomography (CT) imaging and Aspergillus IgG antibodies being key. Treatment strategies include surgery, hemoptysis management, and antifungal therapy. Surgery is the curative option. However, reported postoperative mortality rates range from 0% to 5% and complications range from 11% to 63%. Simple aspergilloma generally has a low postoperative mortality rate, making surgery the first choice. Hemoptysis, observed in 50% of CPA patients, is a significant symptom and can be life-threatening. Bronchial artery embolization achieves hemostasis in 64% to 100% of cases, but 50% experience recurrent hemoptysis. The efficacy of antifungal therapy for CPA varies, with itraconazole reported to be 43–76%, voriconazole 32–80%, posaconazole 44–61%, isavuconazole 82.7%, echinocandins 42–77%, and liposomal amphotericin B 52–73%. Combinatorial treatments such as bronchoscopic triazole administration, inhalation, or direct injection of amphotericin B at the site of infection also show efficacy. A treatment duration of more than 6 months is recommended, with better efficacy reported for periods of more than 1 year. In anticipation of improvements in CPA management, ongoing advances in basic and clinical research are expected to contribute to the future of CPA management.

As azole-resistant Aspergillus fumigatus emerges globally, healthcare facilities face mounting challenges in managing invasive aspergillosis. This review synthesizes worldwide azole resistance data to reveal profound regional variability, demonstrating that findings from other regions cannot be directly extrapolated to local settings. Consequently, hospital-level environmental surveillance is crucial for tailoring interventions to local epidemiology and detecting resistant strains in real-time. We outline practical approaches—encompassing sampling site prioritization, diagnostic workflows (culture-based and molecular), and PDCA-driven continuous improvement—so that even resource-limited facilities can manage resistant isolates more effectively. By linking real-time surveillance findings with clinical decisions, hospitals can tailor antifungal stewardship programs and swiftly adjust prophylaxis or treatment regimens. Our approach aims to enable accurate, ongoing evaluations of emerging resistance patterns, ensuring that institutions maintain efficient and adaptive programs. Ultimately, we advocate for sustained, collaborative efforts worldwide, where facilities adapt protocols to local conditions, share data through international networks, and contribute to a global knowledge base on resistance mechanisms. Through consistent application of these recommendations, healthcare systems can better preserve azole efficacy, safeguard immunocompromised populations, and refine infection control practices in the face of evolving challenges.

Acute kidney injury (AKI) often develops during the administration of liposomal amphotericin B (L-AMB), a broad-spectrum antifungal drug. However, clinical recovery approaches for AKI patients administered L-AMB are not well established. This retrospective analysis used the data obtained from hospitals throughout Japan. AKI was defined as a ≥ 1.5-fold increase within 7 days or ≥0.3 mg/dL increase within 2 days in serum creatinine. AKI recovery was defined as a return to creatinine levels below or equal to those recorded before AKI onset. Ninety patients were assessed for recovery from AKI as per the three stages. The incidence of recovery from AKI regardless of its stage was higher, though not significant, in patients administered ≥10 mL/kg/day fluid for 7 consecutive days from AKI onset (63%) than in those who did not (35%, p = 0.053). However, if limited to AKI stage 1 patients, the former group had a significantly higher incidence of recovery (91%) than the latter group (50%, p = 0.017), even after adjusting for confounding factors (odds ratio: 10.135, 95% confidence interval: 1.148–89.513, p = 0.037). The daily fluid volume administered during the 7 consecutive days from AKI onset positively correlated with the recovery from AKI of all stages (p = 0.043). Daily consecutive fluid infusion from AKI onset may be associated with recovery from stage 1 AKI in patients administered L-AMB, with daily fluid volume positively correlating with the incidence of AKI recovery.
