Abstract
Chronic pulmonary aspergillosis (CPA) is a spectrum of several progressive disease manifestations caused by Aspergillus species in patients with underlying structural lung diseases. Duration of symptoms longer than three months distinguishes CPA from acute and subacute invasive pulmonary aspergillosis. CPA affects over 3 million individuals worldwide. Its diagnostic approach requires a thorough Clinical, Radiological, Immunological and Mycological (CRIM) assessment. The diagnosis of CPA requires (1) demonstration of one or more cavities with or without a fungal ball present or nodules on chest imaging, (2) direct evidence of Aspergillus infection or an immunological response to Aspergillus species and (3) exclusion of alternative diagnoses, although CPA and mycobacterial disease can be synchronous. Aspergillus antibody is elevated in over 90% of patients and is the cornerstone for CPA diagnosis. Long-term oral antifungal therapy improves quality of life, arrests haemoptysis and prevents disease progression. Itraconazole and voriconazole are alternative first-line agents; voriconazole is preferred for patients with contra-indications to itraconazole and in those with severe disease (including large aspergilloma). In patients co-infected with tuberculosis (TB), it is not possible to treat TB with rifampicin and concurrently administer azoles, because of profound drug interactions. In those with pan-azole resistance or intolerance or progressive disease while on oral triazoles, short-term courses of intravenous liposomal amphotericin B or micafungin is used. Surgery benefits patients with well-circumscribed simple aspergillomas and should be offered earlier in low-resource settings.

Abstract
Fungi of the genus Aspergillus are ubiquitously present. Even though humans inhale Aspergillus spores daily under natural conditions, Aspergillus-associated pulmonary diseases only occur under special circumstances. Whether an Aspergillus-associated disease develops and which type of Aspergillus-associated disease develops depends on the constitution of the host. The spectrum of Aspergillus-associated pulmonary diseases ranges from allergic diseases, such as hypersensitivity pneumonitis to allergic infectious diseases, such as allergic bronchopulmonary aspergillosis (ABPA) and bronchocentric granulomatosis (BG) to infectious diseases, such as invasive (IA) or semi-invasive aspergillosis (SIA) and chronic pulmonary aspergillosis (CPA). Identification of Aspergillus spp. from sputum or bronchopulmonary secretions is not sufficient for a definitive diagnosis of Aspergillus-associated infections. The gold standard is the identification of Aspergillus spp. from lung tissue by culture or by histopathological methods; however, in clinical practice the decision to initiate antifungal therapy is more often based on immunological methods, such as the detection of Aspergillus-specific IgG antibodies from peripheral blood or galactomannan antigens from bronchoalveolar lavages. Acute IA or SIA infections have a high mortality and require immediate antifungal therapy. With rare exceptions CPA cannot be cured by medicinal therapy alone; however, active CPA can be brought into remission with antifungal therapy. Eradication of Aspergillus in CPA can as a rule only be successful using a combined antimycotic and surgical intervention.

[PMID: 29634721 PMCID: PMC5892866 DOI: 10.1371/journal.pone.0193732] [Citation(s) in RCA: 62] [Impact Index Per Article: 10.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/14/2017] [Accepted: 02/16/2018] [Indexed: 11/18/2022] Open
Abstract
There is a paucity of evidence surrounding the optimal antifungal therapy for use in chronic pulmonary aspergillosis (CPA) and the duration of therapy remains unclear. We retrospectively evaluated treatment outcomes, including change in quality of life scores (St George’s Respiratory Questionnaire (QoL)), weight and Aspergillus IgG at 6 and 12 months following initiation of therapy in a cohort of 206 CPA patients referred to the UK National Aspergillosis Centre (NAC), Manchester between April 2013 and March 2015. One hundred and forty-two patients (69%) were azole naïve at presentation and 105 (74%) (Group A) were commenced on itraconazole, 27 (19%) on voriconazole, and 10 (7%) were not treated medically. The remainder (64 patients, 31%) had previously trialled, or remained on, azole therapy at inclusion (Group B) of whom 46 (72%) received itraconazole, 16 (25%) voriconazole, and 2 (3%) posaconazole. Initial therapy was continued for 12 months in 78 patients (48%) of those treated; the azole was changed in 62 (32%) patients and discontinued in 56 (29%) patients for adverse reactions (32, 57%), azole resistance (11, 20%), clinical failure (8, 14%) or clinical stability (5, 9%). Azole discontinuation rates were higher in Group B than in Group A (42% vs. 22%, p = 0.003). For all patients who survived, weight increased (median of 62.2Kg at baseline, to 64.8 at 12 months), mean Aspergillus IgG declined from 260 (baseline) to 154 (12 months) and QoL improved from 62.2/100 (baseline) to 57.2/100 (12 months). At 12 months, there was no difference in median survival between Groups A and B (95% vs. 91%, p = 0.173). The rate of emergence of resistance during therapy was 13% for itraconazole compared to 5% for voriconazole. Bronchial artery embolization was done in 9 (4.4%) patients and lobectomy in 7 (3.2%). The optimal duration of azole therapy in CPA is undetermined due to the absence of evidenced based endpoints allowing clinical trials to be undertaken. However we have demonstrated itraconazole and voriconazole are modestly effective for CPA, especially if given for 12 months, but fewer than 50% of patients manage this duration. This suggests extended therapy may be required for demonstrable clinical improvement.

Micafungin Plasma Levels Are Not Affected by Continuous Renal Replacement Therapy: Experience in Critically Ill Patients. Antimicrob Agents Chemother 2017; 61:AAC.02425-16.

Abstract
Critically ill patients often experience acute kidney injury and the need for renal replacement therapy in the course of their treatment in an intensive care unit (ICU). These patients are at an increased risk for candidiasis. Although there have been several reports of micafungin disposition during renal replacement therapy, to this date there are no data describing the elimination of micafungin during high-dose continuous venovenous hemodiafiltration with modified AN69 membranes. The aim of this prospective open-label pharmacokinetic study was to assess whether micafungin plasma levels are affected by continuous hemodiafiltration in critical ill patients using the commonly employed AN69 membrane. A total of 10 critically ill patients with micafungin treatment due to suspected or proven candidemia were included in this trial. Prefilter/postfilter micafungin clearance was measured to be 46.0 ml/min (±21.7 ml/min; n = 75 individual time points), while hemofilter clearance calculated by the sieving coefficient was 0.0038 ml/min (±0.002 ml/min; n = 75 individual time points). Total body clearance was measured to be 14.0 ml/min (±7.0 ml/min; n = 12). The population area under the curve from 0 to 24 h (AUC0-24) was calculated as 158.5 mg · h/liter (±79.5 mg · h/liter; n = 13). In spite of high protein binding, no dose modification is necessary in patients receiving continuous venovenous hemodiafiltration with AN69 membranes. A dose elevation may, however, be justified in certain cases. (This study has been registered at ClinicalTrials.gov under identifier NCT02651038.).

Abstract
Chronic pulmonary aspergillosis (CPA) is an uncommon and problematic pulmonary disease, complicating many other respiratory disorders, thought to affect ~240 000 people in Europe. The most common form of CPA is chronic cavitary pulmonary aspergillosis (CCPA), which untreated may progress to chronic fibrosing pulmonary aspergillosis. Less common manifestations include: Aspergillus nodule and single aspergilloma. All these entities are found in non-immunocompromised patients with prior or current lung disease. Subacute invasive pulmonary aspergillosis (formerly called chronic necrotising pulmonary aspergillosis) is a more rapidly progressive infection (<3 months) usually found in moderately immunocompromised patients, which should be managed as invasive aspergillosis. Few clinical guidelines have been previously proposed for either diagnosis or management of CPA. A group of experts convened to develop clinical, radiological and microbiological guidelines. The diagnosis of CPA requires a combination of characteristics: one or more cavities with or without a fungal ball present or nodules on thoracic imaging, direct evidence of Aspergillus infection (microscopy or culture from biopsy) or an immunological response to Aspergillus spp. and exclusion of alternative diagnoses, all present for at least 3 months. Aspergillus antibody (precipitins) is elevated in over 90% of patients. Surgical excision of simple aspergilloma is recommended, if technically possible, and preferably via video-assisted thoracic surgery technique. Long-term oral antifungal therapy is recommended for CCPA to improve overall health status and respiratory symptoms, arrest haemoptysis and prevent progression. Careful monitoring of azole serum concentrations, drug interactions and possible toxicities is recommended. Haemoptysis may be controlled with tranexamic acid and bronchial artery embolisation, rarely surgical resection, and may be a sign of therapeutic failure and/or antifungal resistance. Patients with single Aspergillus nodules only need antifungal therapy if not fully resected, but if multiple they may benefit from antifungal treatment, and require careful follow-up.

Abstract
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.

Abstract
BACKGROUND Chronic pulmonary aspergillosis (CPA) is an infectious disease that progressively destroys lung tissue. To date, no longitudinal data on the efficacy of antifungal treatment on health status in CPA patients exist. METHODS Using the standardized St George's Respiratory Questionnaire, the health status of 122 patients with was assessed at baseline and quarterly over 12 months. The score range was 0-100, where higher score indicates worse heath status, and a change of ≥4 was deemed the minimal clinically important difference. Lung function, body mass index, Medical Research Council dyspnea scale, disease severity, and demographic data were reported. RESULTS Mean age of patients was 59 years, and 45% were female. Overall, patients with CPA had substantial health status impairment at baseline. After treatment, 47%-50% gained substantial health improvement with a mean reduction of score of 14 at both 6 and 12 months, whereas 32% deteriorated with a mean rise of score of 11 and 14 after 6 and 12 months of treatment and observation, respectively, and 21% were not much different (stable). Patients gained therapeutic benefit irrespective of their illness severity where >50% of those who had "poor" and "very poor" status at baseline improved with score reduction of ≥4 after 6 months of treatment. Replicating this analysis using a health status category, we found that at least 50% of patients with a "poor/very poor" health status category at baseline improved significantly to "fair" or "good/very good" categories. Side effects burdened health status considerably. In multivariate analysis, dyspnea and disease severity significantly defined health status impairment. CONCLUSIONS Antifungal therapy improved health status and prevented CPA progression in most patients.

Abstract
BACKGROUND Though various clinical conditions of aspergillosis can occur, depending essentially on the host's immunological status, the focus of research in North American and European countries has mainly been on invasive pulmonary aspergillosis in immunocompromised patients. There are, however, also many problems to overcome in chronic forms of aspergillosis. One of those problems is that there are no codified treatment guidelines for chronic pulmonary aspergillosis (CPA). Especially in Japan, this issue is more serious, because there are more cases with CPA due to the many aged people with past history of tuberculosis. Several clinical cases and case series have reported the usefulness of the various antifungal agents that are available. The new triazole, voriconazole, in particular, seems to be effective in the treatment of CPA. The aim of the present study is to evaluate the efficacy and safety of voriconazole in the treatment of CPA in non-immunocompromised patients. PATIENTS AND METHODS We conducted a prospective, open-label, non-comparative, multicenter study over a 2-year period. For inclusion in the study, patients with confirmed or probable CPA were recruited in 11 hospitals of the National Hospital Organization in Japan. Clinical, radiological, serological, and mycological data were collected at baseline and 12 weeks after treatment or at the end of treatment. RESULTS Among 77 patients enrolled in the study, 71 patients (mean age 65.9 years, 56 males and 15 females) were eligible for the study. All of the eligible patients presented with underlying lung diseases, including sequelae of tuberculosis (n = 35), non-tuberculous mycobacterial lung disease (n = 8), chronic obstructive pulmonary disease (COPD) (n = 8), interstitial pneumonia (n = 7), cystic lung disease (n = 4), pneumothorax (n = 3), bronchial cancer (n = 1), and others (n = 5). Voriconazole was indicated in 48 cases (68 %) as the first-line treatment for CPA and 23 patients previously received other antifungal therapies. Based on a composite of clinical, radiologic, serological, and mycologic criteria, good response was seen in 43 patients (60.6 %), no response was observed in 19 patients (26.8 %), and 4 cases (5.6 %) got worse. Five patients (7.0 %) were unassessable for efficacy. The common adverse events were visual disturbances (17 patients, 23.9 %), abnormal liver function test results (12 patients, 16.9 %), adverse psychological effects (3 patients, 4.2 %), and others (10 patients, 14.0 %). Treatment with voriconazole had to be stopped in 2 cases (2.8 %) because of serious adverse events (abnormal liver function test results). There was no association between adverse effects and trough voriconazole levels in serum. CONCLUSIONS In Japan, voriconazole provides effective therapy of CPA in non-immunocompromised patients with an acceptable level of toxicity.
