Drug-drug interactions in the management of non-tuberculous mycobacterial infections.

Non-tuberculous mycobacterial pulmonary disease (NTM-PD) is a refractory chronic respiratory infectious disease and its prevalence is increasing globally. The standard treatment regimen for NTM-PD involves long-term multidrug therapy including macrolides. The incidence of adverse events is high given the advanced age of many NTM-PD patients. In addition, drug-drug interactions under coexisting conditions add additional complexity. Despite guidelines advocating multidrug therapy for NTM-PD, low adherence rates probably owing to the relatively frequent adverse events and drug interactions. An appropriate treatment regimen can improve the bacteriological response rates, reduce the development of macrolide resistance, and mitigate adverse events. Of particular concern are the interactions arising from new complications that develop with NTM-PD. Notably, chronic pulmonary aspergillosis occasionally co-infects NTM-PD, which can lead to poor prognosis. The primary therapeutic modality for chronic pulmonary aspergillosis is the azoles. However, the interaction with rifamycin is problematic, making it challenging to continue standard treatment for NTM-PD and requiring drug adjustments. The implications of rifamycin extend beyond chronic pulmonary aspergillosis, impacting various other diseases such as those requiring immunosuppressive agents and AIDS patients requiring antiretroviral therapy. Hence, a comprehensive consideration of drug interactions is imperative for the initiation of NTM-PD treatment. This mini-review focuses on drug-drug interactions in a multidrug regimen for NTM-PD and discusses the essential points to be considered in the treatment of NTM.

Retrospective Comparison of Two Aspergillus IgG Enzyme Immunoassays for Diagnosing Pulmonary Aspergillosis.

Aspergillus-specific antibodies are diagnostic indicators of allergic bronchopulmonary aspergillosis (ABPA) and chronic pulmonary aspergillosis (CPA). Tests for detecting Aspergillus-specific antibodies were not used clinically in Japan, and the production of the Aspergillus precipitin test was discontinued. Thus, alternative tests for diagnosing aspergillosis are urgently needed. We retrospectively evaluated 64 patients with suspected ABPA and CPA who underwent precipitin antibody testing. Serum Aspergillus IgG levels were measured and compared using the Bordier Aspergillus fumigatus ELISA and the Platelia Aspergillus IgG (Bio-Rad) kits. Of the participants, 18 were diagnosed with CPA, and 8 were diagnosed with ABPA. Both the Bordier and Bio-Rad kits showed high sensitivity and specificity for CPA and ABPA. The area under the receiver operating characteristic curves for the Bordier and Bio-Rad kits were 0.97 and 0.95, respectively, for CPA, and 0.89 and 0.91, respectively, for ABPA. In contrast to the Bordier kit, the Bio-Rad kit showed relatively low anti-Aspergillus IgG levels and lower sensitivity to non-fumigatus Aspergillus infections. The Aspergillus-specific IgG ELISA tests showed sufficient diagnostic accuracy. Therefore, these assays are recommended as alternatives to the precipitin kit for diagnosing aspergillosis in clinical settings in Japan.

Optimized Antifungal Therapy for Chronic Pulmonary Aspergillosis.

Chronic pulmonary aspergillosis (CPA) represents a spectrum of lung disorders caused by local proliferation of Aspergillus hyphae in individuals with non-systemic or mildly systemic immunodepression or altered pulmonary integrity due to underlying disease. While long-term systemic antifungal treatment is still the mainstay for management, surgery is considered mainly in rarer invasive disease manifestations such as sinusitis and osteomyelitis. Optimal application of existing antifungal agents with suitable pharmacokinetic properties is important for the treatment of diseases such as CPA, which requires long-term use. Appropriate management of side effects by therapeutic drug monitoring, maintenance of adherence, and assessment of drug resistance to Aspergillus can provide safe and effective treatment in the future. Most available antifungal agents for the management of mycoses in humans have disadvantages that can limit their use in clinical practice. By contrast, second generation antifungals such as triazoles have advantages of extended antifungal spectrum and availability in both oral and intravenous formulations. Isavuconazole, a new extended spectrum triazole, has been shown to be effective against Aspergillus. The safety profile and excellent pharmacokinetic characteristics of isavuconazole make it an attractive option for treatment of invasive fungal infections including CPA. With this drug now available in Japan, new evidence is expected to expand treatment options. This review focuses on the selection of antifungal agents based on national and international guidelines and the characteristics of each agent for their appropriate use in CPA.

Chronic pulmonary aspergillosis in Taiwan: Disease burden, diagnosis, treatment, and outcomes.

Aspergillus is a common filamentous fungus found in various natural environments, with spores frequently inhaled by humans. While healthy individuals typically resist infection, immunocompromised individuals and those with pre-existing lung diseases are at higher risk for aspergillosis. Chronic pulmonary aspergillosis (CPA) often develops in individuals with conditions like tuberculosis and chronic obstructive pulmonary disease. Recent studies in Taiwan reveal a significant incidence of CPA among elderly patients with these underlying conditions. The most common clinical manifestations include cavitation, nodules, and consolidation in the lungs. Aspergillus-specific IgG antibodies have emerged as key diagnostic markers, with varying optimal cut-off values across different regions. Studies indicate a strong correlation between high IgG levels and severe CPA, alongside associations with specific radiographic features. Additionally, elevated inflammatory markers such as IL-1ß and TNF-α are linked to poor outcomes, emphasizing the need for early detection and intervention. The preferred treatment regimen consists of itraconazole, voriconazole, posaconazole, and isavuconazole, with itraconazole and voriconazole being the most extensively documented in the context of CPA. Overall, this review underscores the importance of localized diagnostic validation and comprehensive studies to improve the understanding and treatment of CPA in Taiwan.

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.

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.

Clinical significance of chronic pulmonary aspergillosis in lung cancer patients undergoing anticancer drug therapy.

BACKGROUND: Advances in anticancer drugs for lung cancer (LC) have improved the prognosis of LC. Chronic pulmonary aspergillosis (CPA) is a progressive and often exacerbating respiratory disease with a poor prognosis. To date, the prognosis of LC complicated by CPA has not been elucidated. This study investigated the clinical implications of concomitant CPA in patients with LC undergoing anticancer drug treatment. METHODS: Between January 2010 and May 2020, we consecutively enrolled patients with LC complicated with CPA at five different institutions in Japan. We analyzed patients with LC complicated by CPA who received anticancer drug treatment. RESULTS: A total of 10 patients with LC complicated by CPA received anticancer drug treatment. The median overall survival (OS) was 14.57 months (95% confidence interval [CI]: 5.37-21.67). The cause of death in all patients was LC. Six of the seven patients with LC did not show worsening pulmonary aspergillosis lesions during the anticancer drug treatment. Although two patients discontinued anticancer drug treatment due to pneumonitis, CPA complications did not interfere with the continuation of anticancer drug treatment. In univariate analyses, squamous histology (p = 0.01) and body mass index (<18.5 kg/m2) (p = 0.0008) were significantly associated with poorer OS. CONCLUSIONS: This study demonstrated that the cause of death in LC patients with concomitant CPA who received anticancer drug treatments and effective antifungal treatment was LC progression. Further large-scale studies are needed to identify the effect of CPA in patients with LC.

Chronic pulmonary aspergillosis: comprehensive insights into epidemiology, treatment, and unresolved challenges.

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.

Five cases of pulmonary Aspergillus nodules diagnosed at surgery and by pathology in immunocompetent patients, with a literature review.

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

Report 5 cases of pulmonary aspergillosis nodules confirmed by histopathology after surgical resection. Pulmonary aspergillosis nodules are a relatively rare manifestation in the spectrum of chronic pulmonary aspergillosis. This article reports five cases of pulmonary aspergillosis nodules confirmed by surgical resection and histopathological examination, all of which were patients with normal immune function, atypical clinical symptoms, varying severity, and normal Galactomannan (GM) tests. All five cases did not receive antifungal treatment after surgery, and the nodules did not recur during regular follow-up. The diagnosis of pulmonary aspergillosis nodules is difficult, and lung biopsy and bronchoalveolar lavage fluid (BALF) metagenomics next generation sequencing (mNGS) may be considered. There are various treatment methods, including surgical treatment, antifungal drug therapy, and sometimes local bronchial perfusion therapy can also be considered.

Chronic pulmonary aspergillosis incidence in newly detected pulmonary tuberculosis cases during follow-up.

BACKGROUND: Chronic pulmonary aspergillosis (CPA) is known to complicate patients with post-tubercular lung disease. However, some evidence suggests that CPA might co-exist in patients with newly-diagnosed pulmonary tuberculosis (P.TB) at diagnosis and also develop during therapy. The objective of this study was to confirm the presence of CPA in newly diagnosed P.TB at baseline and at the end-of-TB-therapy. MATERIALS AND METHODS: This prospective longitudinal study included newly diagnosed P.TB patients, followed up at third month and end-of-TB-therapy with symptom assessment, anti-Aspergillus IgG antibody and imaging of chest for diagnosing CPA. RESULTS: We recruited 255 patients at baseline out of which 158 (62%) completed their follow-up. Anti-Aspergillus IgG was positive in 11.1% at baseline and 27.8% at end-of-TB-therapy. Overall, proven CPA was diagnosed in 7% at baseline and 14.5% at the end-of-TB-therapy. Around 6% patients had evidence of aspergilloma in CT chest at the end-of-TB-therapy. CONCLUSIONS: CPA can be present in newly diagnosed P.TB patients at diagnosis and also develop during anti-tubercular treatment. Patients with persistent symptoms or developing new symptoms during treatment for P.TB should be evaluated for CPA. Whether patients with concomitant P.TB and CPA, while receiving antitubercular therapy, need additional antifungal therapy, needs to be evaluated in future studies.

Proteome and Dihydrorhodamine Profiling of Bronchoalveolar Lavage in Patients with Chronic Pulmonary Aspergillosis.

Neutrophil and (alveolar) macrophage immunity is considered crucial for eliminating Aspergillus fumigatus. Data derived from bronchoalveloar lavage (BAL) characterizing the human immuno-pulmonary response to Aspergillus fumigatus are non-existent. To obtain a comprehensive picture of the immune pathways involved in chronic pulmonary aspergillosis (CPA), we performed proteome analysis on AL of 9 CPA patients and 17 patients with interstitial lung disease (ILD). The dihydrorhodamine (DHR) test was also performed on BAL and blood neutrophils from CPA patients and compared to blood neutrophils from healthy controls (HCs). BAL from CPA patients primarily contained neutrophils, while ILD BAL was also characterized by a large fraction of lymphocytes; these differences likely reflecting the different immunological etiologies underlying the two disorders. BAL and blood neutrophils from CPA patients displayed the same oxidative burst capacity as HC blood neutrophils. Hence, immune evasion by Aspergillus involves other mechanisms than impaired neutrophil oxidative burst capacity per se. CPA BAL was enriched by proteins associated with innate immunity, as well as, more specifically, with neutrophil degranulation, Toll-like receptor 4 signaling, and neutrophil-mediated iron chelation. Our data provide the first comprehensive target organ-derived immune data on the human pulmonary immune response to Aspergillus fumigatus.

Prevalence of Chronic Pulmonary Aspergillosis in Two (2) Tuberculosis Treatment Clinics in Lagos, Nigeria: A Prospective Longitudinal Study.

Background: Chronic pulmonary aspergillosis (CPA) is an underrecognized but common complication of pulmonary tuberculosis. In Nigeria, a tuberculosis-endemic country, there is currently no provision to monitor the development of CPA in patients treated for tuberculosis. This study determined the prevalence and incidence of CPA in Lagos, Nigeria. Methods: A prospective longitudinal study of patients with previously managed tuberculosis was conducted between June 2021 and May 2022. The study cohorts were assessed at 3-month intervals, and the following were collected: sociodemographic data, chest radiographic findings, sputum samples for fungal culture, and venous blood samples for Aspergillus immunoglobulin G estimation. CPA cases were determined using the case definition for resource-constrained countries. Descriptive and inferential statistics were used, and significance was set at a probability of 5% (P < .05). Results: Of the 141 patients recruited, 79 (56.0%) were in the retreatment and 62 (44.0%) in the posttreatment tuberculosis group. The median age (interquartile range) was 40 (30-52) years, with a male-to-female ratio of 1.1:1. Ninety-seven patients (69%) had a GeneXpert test done, of whom 63 (64.9%) were GeneXpert negative. Cough was the most common symptom, with 15 (11%) patients having hemoptysis. The rate of CPA increased steadily as the study progressed: 44 (31.2%) at commencement, 45 (34.9%) at 3 months, 49 (42.6%) at 6 months, and 51 (54.3%) at 9 months. Thus, the overall prevalence of CPA was 49.7%, and the incidence was 6.1%. Conclusions: CPA is common in Nigeria and its true burden may still be underestimated. Increased awareness of CPA as a posttuberculosis lung disease is advocated. Evaluation for CPA should be incorporated in patients' work-up for tuberculosis.

Aspergillus nodules: Natural history and the effect of antifungals.

BACKGROUND: Aspergillus nodules are classified as a subset of chronic pulmonary aspergillosis. The optimal management approach is not known as their natural evolution following biopsy, the rate of progression to chronic cavitary pulmonary aspergillosis (CCPA) and the effect of antifungal treatment have not been described. OBJECTIVES: To describe the clinical course of patients diagnosed with Aspergillus nodules and the effect of antifungal treatment. PATIENTS/METHODS: We present a series of 23 patients with histologically confirmed Aspergillus nodules and describe serial imaging, antifungal treatment and progression to other diagnoses. RESULTS: Thirteen patients were diagnosed after a CT-guided biopsy and 10 after surgical resection. Among those who had CT-guided biopsy, 8 did not receive antifungal treatment; the nodule was stable or smaller in all cases on subsequent CT scan after a mean of 15.5 months. However, one patient developed squamous cell carcinoma after 16 months and another developed CCPA after 7 months. Among the 5 patients who received antifungals for at least 4 weeks, the nodule was smaller in 1 and stable in 4. One patient developed CCPA 3 years after the biopsy. No patient who had a surgical resection subsequently had a CCPA diagnosis. CONCLUSION: Most Aspergillus nodules remained stable or improved following biopsy, irrespective of the effect of antifungals. However, CCPA can develop occasionally in patients with Aspergillus nodules and ongoing radiological follow-up may be warranted when the nodule is not resected.

Re-estimation of the burden of serious fungal diseases in Uganda.

Background: It is of utmost importance to monitor any change in the epidemiology of fungal diseases that may arise from a change in the number of the at-risk population or the availability of local data. Objective: We sought to update the 2015 publication on the incidence and prevalence of serious fungal diseases in Uganda. Methods: Using the Leading International Fungal Education methodology, we reviewed published data on fungal diseases and drivers of fungal diseases in Uganda. Regional or global data were used where there were no Ugandan data. Results: With a population of ~45 million, we estimate the annual burden of serious fungal diseases at 4,099,357 cases (about 9%). We estimated the burden of candidiasis as follows: recurrent Candida vaginitis (656,340 cases), oral candidiasis (29,057 cases), and esophageal candidiasis (74,686 cases) in HIV-infected people. Cryptococcal meningitis annual incidence is estimated at 5553 cases, Pneumocystis pneumonia at 4604 cases in adults and 2100 cases in children. For aspergillosis syndromes, invasive aspergillosis annual incidence (3607 cases), chronic pulmonary aspergillosis (26,765 annual cases and 63,574 5-year-period prevalent cases), and prevalence of allergic bronchopulmonary aspergillosis at 75,931 cases, and severe asthma with fungal sensitization at 100,228 cases. Tinea capitis is common with 3,047,989 prevalent cases. For other mycoses, we estimate the annual incidence of histoplasmosis to be 646 cases and mucormycosis at 9 cases. Conclusion: Serious fungal diseases affect nearly 9% of Ugandans every year. Tuberculosis and HIV remain the most important predisposition to acute fungal infection necessitating accelerated preventive, diagnostic, and therapeutic interventions for the management of these diseases.

How common are serious fungal infections in Uganda? Why was the study done? This study was conducted to provide an updated understanding of the occurrence and impact of serious fungal diseases in Uganda. The aim was to monitor changes in the epidemiology of fungal diseases related to shifts in the at-risk population or the availability of local data. What did the researchers do? Utilizing the Leading International Fungal Education methodology, the research team systematically reviewed published data on fungal diseases in Uganda. In instances where Ugandan data was unavailable, regional, or global data were incorporated. This method allowed for a thorough examination of the incidence and prevalence of various serious fungal diseases, considering the local context. What did the researchers find? With a population of approximately 45 million, the study estimated that nearly 9% of Ugandans, totalling around 4,099,357 individuals, are affected by serious fungal diseases annually. Notable findings include the prevalence of recurrent Candida vaginitis, oral candidiasis, and oesophageal candidiasis in HIV-infected individuals. Cryptococcal meningitis and Pneumocystis pneumonia were identified as significant contributors, along with various aspergillosis syndromes and widespread cases of tinea capitis. What do the findings mean? These findings underscore the substantial impact of serious fungal diseases on the health of almost 9% of the Ugandan population each year. Recognizing tuberculosis and HIV as major predisposing factors, the study calls for urgent interventions to prevent, diagnose, and treat these diseases effectively. The identified targets, including improved access to essential antifungal medications, training of health care workers on fungal diseases, and increasing access to essential diagnostics. These interventions can significantly contribute to improving public health outcomes in Uganda.

Successful Treatment of Eosinophilic Granulomatosis With Polyangiitis: A Case of Refractory Peripheral Neuropathy and Comorbid Chronic Progressive Pulmonary Aspergillosis Treated With Mepolizumab.

Eosinophilic granulomatosis with polyangiitis (EGPA) is a systemic necrotizing vasculitis accompanied by granulomas and eosinophilic inflammation, exhibiting marked peripheral blood eosinophiliaandasthma. Neuropathy is a difficult-to-treat common manifestation that frequently remains after achieving clinical remission with current therapy in a subpopulation of patients with EGPA with or without life-threatening organ involvement. Refractory neuropathy regularly reduces the quality of life and requires glucocorticoids (GCs) and/or immunosuppressants for a long time. Long-term immunosuppressive therapy is a factor associated with a high risk of adverse effects. Mepolizumab, at three times the dose for severe asthma, provides benefits to induce the remission of relapsing or refractory EGPA and to reduce the doses of GC. Here, we present a case of EGPA successfully treated with mepolizumab at the reference dose for severe asthma. In this case, mepolizumab resolved peripheral neuropathy resistant to corticosteroids, immunosuppressants, and intravenous immunoglobulin and contributed to the improvement of comorbid chronic pulmonary aspergillosis during GC dose reduction.

Chronic pulmonary aspergillosis - a guide for the general physician.

This collaborative article presents a review of chronic pulmonary aspergillosis (CPA) from the perspective of a multidisciplinary team comprising of respiratory physicians, radiologists, mycologists, dietitians, pharmacists, physiotherapists and palliative care specialists. The review synthesises current knowledge on CPA, emphasising the intricate interplay between clinical, radiological, and microbiological aspects. We highlight the importance of assessing each patient as multidisciplinary team to ensure personalised treatment strategies and a holistic approach to patient care.

Impact of Ascaris lumbricoides infection on the development of chronic pulmonary aspergillosis in patients with COPD.

The aetiopathogenesis of chronic obstructive pulmonary disease (COPD) remains unclear. The aim of our study was to determine the possible influence of Ascaris lumbricoides on the development of chronic pulmonary aspergillosis (CPA) in patients with COPD. The prevalence of A. lumbricoides in patients with COPD with CPA (19.05%) was significantly higher than that in those without (9.20%) and controls (4.9%) (p < 0.05). Trends in levels of Interleukin-1ß and of tumour necrosis factor α suggest ascariasis increases susceptibility to Aspergillus sp. in patients with COPD and can be considered an additional risk factor for CPA.

Chronic pulmonary Aspergillosis in a patient with poorly controlled diabetes: A case report and literatures review.

Chronic pulmonary aspergillosis (CPA) often manifests in patients with a history of pulmonary tuberculosis and is typically characterized by recurrent hemoptysis, weight loss, and frequently coexists with poorly controlled diabetes. While weight gain is acknowledged as a valuable clinical marker for monitoring therapeutic responses in CPA, there is a scarcity of case reports exploring this aspect. Furthermore, the impact of stringent blood sugar management in diminishing CPA activity and preventing the recurrence of hemoptysis is also underreported. In this context, we present the case of a 64-year-old male who experienced massive hemoptysis. He had a background of uncontrolled diabetes and a history of fully treated pulmonary tuberculosis. Following therapeutic embolization, he was diagnosed with CPA that had transformed into invasive pulmonary aspergillosis (IPA) and underwent antifungal therapy for 9 months. Notably, we observed an inverse correlation between the patient's improved blood sugar control and weight gain with the serum IgG levels for Aspergillosis. This case highlights the potential benefits of non-invasive monitoring of CPA activity and the identification of treatment responders through effective blood sugar management and weight gain.

An immunocompetent case of chronic pulmonary aspergillosis caused by Aspergillusviridinutans.

We encountered an extremely rare immunocompetent case of chronic pulmonary aspergillosis (CPA) caused by Aspergillus viridinutans. A 74-year-old woman was admitted with fever and hemoptysis. Chest computed tomography revealed a nodule in the left upper lobe. Bronchoscopy was performed, and the transbronchial biopsy specimen revealed Aspergillus fungi. Treatment of the nodule was initially ineffective with voriconazole but effective with liposomal amphotericin B. The causative organism was later identified as A. viridinutans based on the gene sequence of ß-tubulin. This is the first immunocompetent case of CPA caused by A. viridinutans.

Overlap of Chronic Pulmonary Aspergillosis on Allergic Bronchopulmonary Aspergillosis.

An 80-year-old woman who developed allergic bronchopulmonary aspergillosis (ABPA) was admitted to our institution in 2023 for an enlarged pulmonary mass lesion. She had developed ABPA in 2017, and corticosteroid therapy had improved the mucoid impaction of the bronchi. Because part of the lesion remained, increased doses of corticosteroid, antifungals, and biologics were administered, but the pulmonary lesion enlarged in 2022. Bronchoscopy showed necrotic tissue in the bronchial lumen, and bronchial washing fluid showed neutrophilic inflammation and fungal hyphae. We subsequently diagnosed her as having chronic pulmonary aspergillosis overlapping ABPA, and voriconazole was started that resulted in shrinkage of the nodules.
