Clinical Features, Treatment Outcome and Potential risk Factors for Recurrence Among Patients with Chronic Pulmonary Aspergillosis in a Resource-limited Setting: A Retrospective Observational Study. Mycopathologia 2024; 189:76. [PMID: 39172211 DOI: 10.1007/s11046-024-00884-9] [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: 03/06/2024] [Accepted: 08/09/2024] [Indexed: 08/23/2024]
Abstract
OBJECTIVE To evaluate the clinical characteristics and treatment outcomes of patients with chronic pulmonary aspergillosis (CPA) and to determine risk factors for disease recurrence. METHODS A total of 43 patients with CPA (mean ± SD age: 61.4 ± 10.5 years, 83.7% were males) were included in this retrospective study. Data on demographic, clinical and disease-related characteristics, galactomannan (GM) test positivity in bronchoalveolar lavage (BAL) samples, histopathological diagnosis, imaging (CT) findings and CPA forms, antifungal therapy, recurrence rate and time to recurrence were recorded. RESULTS Chronic obstructive pulmonary disease (COPD;76.7%) was the leading predisposing factor, and the aspergillus nodule (37.2%) was the most prevalent CPA form.GM test positivity was noted in 89.7% (35/39) of BAL samples. Median duration of voriconazole treatment was 180 days. CPA recurrence was noted in 14.0% of patients, while the comorbid tuberculosis sequela (66.7% vs. 16.2%, p = 0.02) and mild immunosuppressive disorder (100.0% vs. 51.4%, p = 0.032) were significantly more common in patients with recurrence vs. those without recurrence. Recurrence rate was 50.0% (3 of 6 patients) in patients with simple aspergilloma, and ranged from 0.0% to 25.0% in those with other CPA forms. Treatment duration and time to recurrence ranged 70-270 days and 1.1-37 months, respectively in simple aspergilloma, while they were ranged 150-180 days and 30-43.3 months, respectively in other CPA forms. CONCLUSIONS Our findings indicate the importance of considering CPA in differential diagnosis in patients with predisposing conditions, and emphasize the tuberculosis sequela, immunosuppressive disorder and the certain CPA forms managed with shorter duration of antifungal therapy (i.e., simple aspergilloma) as the potential risk factors of CPA recurrence.

[PMID: 38899061 PMCID: PMC11186400 DOI: 10.1177/20499361241253751] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/17/2023] [Accepted: 04/23/2024] [Indexed: 06/21/2024] Open
Abstract
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.

Abstract
Aspergillus fumigatus is an environmental saprophyte and opportunistic fungal pathogen of humans. The aim of the work presented here was to examine the effect of serially subculturing A. fumigatus on agar generated from Galleria mellonella larvae in order to characterize the alterations in the phenotypes that might occur. The passaged strains showed alterations in virulence, antifungal susceptibility, and in protein abundances that may indicate adaptation after 25 passages over 231 days on Galleria extract agar. Passaged strains demonstrated reduced virulence in G. mellonella larvae and increased tolerance to hemocyte-mediated killing, hydrogen peroxide, itraconazole, and amphotericin B. A label-free proteomic analysis of control and passaged A. fumigatus strains revealed a total of 3329 proteins, of which 1902 remained following filtration, and 32 proteins were statistically significant as well as differentially abundant. Proteins involved in the response to oxidative stress were altered in abundance in the passaged strain and included (S)-S-oxide reductase (+2.63-fold), developmental regulator FlbA (+2.27-fold), and histone H2A.Z (-1.82-fold). These results indicate that the prolonged subculturing of A. fumigatus on Galleria extract agar results in alterations in the susceptibility to antifungal agents and in the abundance of proteins associated with the oxidative stress response. The phenomenon may be a result of selection for survival in adverse conditions and highlight how A. fumigatus may adapt to tolerate the pulmonary immune response in cases of human infection.

Abstract
BACKGROUND Chronic cavitary pulmonary aspergillosis (CCPA) is the most common form of chronic pulmonary aspergillosis. OBJECTIVE We hypothesise that by observing serial clinical and CT findings of CCPA patients with antifungal therapy, factors helping predict responses to antifungal therapy could be withdrawn. METHODS A total of 31 patients with CCPA who received antifungal therapy for greater than six months and who had serial CT studies were included. Clinical finding analyses were performed at initial and last follow-up CT acquisition dates. Clinical characteristics and CT features were compared between clinically improving or stable and deteriorating groups. RESULTS With antifungal therapy, neutrophil-to-lymphocyte ratio (2.66 vs. 5.12, p = .038) and serum albumin (4.40 vs. 3.85 g/dl, p = .013) and CRP (1.10 vs. 42.80 mg/L, p = .007) were different between two groups. With antifungal therapy, meaningful CT change, regardless of clinical response grouping, was decrease in cavity wall thickness (from 13.70 mm to 8.28 mm, p < .001). But baseline (p = .668) and follow-up (p = .278) cavity wall thickness was not different between two groups. In univariate analysis, initial maximum diameter of cavity (p = .028; HR [0.983], 95% CI [0.967-0.998]) and concurrent NTM infection (p = .030; HR [0.20], 95% CI [0.05-0.86]) were related factors for poor clinical response. CONCLUSIONS With antifungal therapy, cavities demonstrate wall thinning. Of all clinical and radiological findings and their changes, initial large cavity size and concurrent presence of NTM infection are related factors to poor response to antifungal therapy.

Nanotechnology-Based Approaches for Voriconazole Delivery Applied to Invasive Fungal Infections. Pharmaceutics 2023; 15:pharmaceutics15010266.

Abstract
Invasive fungal infections increase mortality and morbidity rates worldwide. The treatment of these infections is still limited due to the low bioavailability and toxicity, requiring therapeutic monitoring, especially in the most severe cases. Voriconazole is an azole widely used to treat invasive aspergillosis, other hyaline molds, many dematiaceous molds, Candida spp., including those resistant to fluconazole, and for infections caused by endemic mycoses, in addition to those that occur in the central nervous system. However, despite its broad activity, using voriconazole has limitations related to its non-linear pharmacokinetics, leading to supratherapeutic doses and increased toxicity according to individual polymorphisms during its metabolism. In this sense, nanotechnology-based drug delivery systems have successfully improved the physicochemical and biological aspects of different classes of drugs, including antifungals. In this review, we highlighted recent work that has applied nanotechnology to deliver voriconazole. These systems allowed increased permeation and deposition of voriconazole in target tissues from a controlled and sustained release in different routes of administration such as ocular, pulmonary, oral, topical, and parenteral. Thus, nanotechnology application aiming to delivery voriconazole becomes a more effective and safer therapeutic alternative in the treatment of fungal infections.

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. THE LANCET. INFECTIOUS DISEASES 2022; 22:1052-1061. [PMID: 35429465 DOI: 10.1016/s1473-3099(22)00057-3] [Citation(s) in RCA: 31] [Impact Index Per Article: 15.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/29/2021] [Revised: 01/08/2022] [Accepted: 01/19/2022] [Indexed: 12/11/2022]
Abstract
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.

Abstract
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.

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.
