RESUMO

Invasive aspergillosis is a major cause of infectious disease in immunocompromised patients; however, cardiac involvement in pulmonary aspergillosis is not well-known. Two paediatric patients undergoing chemotherapy were diagnosed with cardiac aspergilloma, accompanied by pulmonary aspergillosis. In both patients, antibiotic and antifungal treatments were initiated immediately after the pneumonia was diagnosed; however, both died of multiple cerebral thromboembolisms.

RESUMO

BACKGROUND: COVID-19 patients on mechanical ventilation are at risk to develop invasive aspergillosis. To provide additional data regarding this intriguing entity, we conducted a retrospective study describing risk factors, radiology and prognosis of this emerging entity in a Brazilian referral centre. METHODS: This retrospective study included intubated (≥18 years) patients with COVID-19 admitted from April 2020 until July 2021 that had bronchoscopy to investigate pulmonary co-infections. COVID-19-associated aspergillosis (CAPA) was defined according to the 2020 European Confederation of Medical Mycology/International Society of Human and Animal Mycosis consensus criteria. The performance of tracheal aspirate (TA) cultures to diagnose CAPA were described, as well as the radiological findings, risk factors and outcomes. RESULTS: Fourteen patients (14/87, 16%) had probable CAPA (0.9 cases per 100 ICU admissions). The sensitivity, specificity, positive predictive value and negative predictive value of TA for the diagnosis of CAPA were 85.7%, 73.1%, 46.2% and 95% respectively. Most of the radiological findings of CAPA were classified as typical of invasive pulmonary aspergillosis (64.3%). The overall mortality rate of probable CAPA was 71.4%. Age was the only independent risk factor for CAPA [p = .03; odds ratio (OR) 1.072]. CAPA patients under renal replacement therapy (RRT) may have a higher risk for a fatal outcome (p = .053, hazard ratio 8.047). CONCLUSIONS: CAPA was a prevalent co-infection in our cohort of patients under mechanical ventilation. Older patients had a higher risk to develop CAPA, and a poor prognosis may be associated with RRT.

RESUMO

Invasive pulmonary aspergillosis (IPA) is a severe infection caused by aspergillus sp. that usually develops in patients with severe immunosuppression. IPA has been recently described in critically ill COVID-19 patients (termed as COVID-associated pulmonary aspergillosis, or CAPA) that are otherwise immunocompetent. In order to describe the characteristics of patients with CAPA, we conducted a retrospective cohort study in a tertiary care center in Mexico City. We included all patients with confirmed COVID-19 admitted to the intensive care unit that had serum or bronchoalveolar lavage galactomannan measurements. We used the criteria proposed by Koehler et al. to establish the diagnosis of CAPA. Main outcomes were the need for invasive mechanical ventilation (IMV) and in-hospital mortality. Out of a total of 83 hospitalized patients with COVID-19 in the ICU, 16 (19.3%) met the criteria for CAPA. All patients diagnosed with CAPA required IMV whereas only 84% of the patients in the non-IPA group needed this intervention (P = 0.09). In the IPA group, 31% (n = 5) of the patients died, compared to 13% (n = 9) in the non-CAPA group (P = 0.08). We conclude that CAPA is a frequent co-infection in critically ill COVID-19 patients and is associated with a high mortality rate. The timely diagnosis and treatment of IPA in these patients is likely to improve their outcome. LAY SUMMARY: We studied the characteristics of patients with COVID-19-associated invasive pulmonary aspergillosis (CAPA). Patients with CAPA tended to need invasive mechanical ventilation more frequently and to have a higher mortality rate. Adequate resources for its management can improve their outcome.

RESUMO

BACKGROUND: The diagnosis of invasive aspergillosis (IA) can be problematic in solid organ transplantation (SOT). The prognosis greatly varies according to the type of transplant, and the impact of prophylaxis is not well defined. PATIENTS AND METHODS: The Diaspersot cohort analyses the impact of IA in SOT in Spain during the last 10 years. Proven and probable/putative IA was included. RESULTS: We analysed 126 cases of IA. The incidences of IA were as follows: 6.5%, 2.9%, 1.8% and 0.6% for lung, heart, liver and kidney transplantation, respectively. EORTC/MSG criteria confirmed only 49.7% of episodes. Tree-in-bud sign or ground-glass infiltrates were present in 56.3% of patients, while serum galactomannan (optical density index >0.5) was positive in 50.6%. A total of 41.3% received combined antifungal therapy. Overall mortality at 3 months was significantly lower (p < 0.001) in lung transplant recipients (14.8%) than in all other transplants [globally: 48.6%; kidney 52.0%, liver 58.3%, heart 31.2%, and combined 42.9%]. Fifty-four percent of episodes occurred despite the receipt of antifungal prophylaxis, and in 10%, IA occurred during prophylaxis (breakthrough infection), with both nebulised amphotericin (in lung transplant recipients) and candins (in the rest). CONCLUSIONS: Invasive aspergillosis diagnostic criteria, applied to SOT patients, may differ from those established for haematological patients. IA in lung transplants has a higher incidence, but is associated with a better prognosis than other transplants. Combination therapy is frequently used for IA in SOT. Prophylactic measures require optimisation of its use within this population.

RESUMO

BACKGROUND: The development of respiratory infections secondary to Aspergillus spp. spores found ubiquitously in the ambient environment is uncommon in immunocompetent patients. Previous reports of invasive upper airway aspergillosis in immunocompetent patients have generally demonstrated the efficacy of treatment regimens utilizing antifungal agents in combination with periodic endoscopic debridement, with symptoms typically resolving within months of initiating therapy. CASE PRESENTATION: A 43-year-old previously healthy female presented with worsening respiratory symptoms after failing to respond to long-term antibiotic treatment of bacterial sinusitis. Biopsy of her nasopharynx and trachea revealed extensive fungal infiltration and Aspergillus fumigatus was isolated on tissue culture. Several months of oral voriconazole monotherapy failed to resolve her symptoms and she underwent mechanical debridement for symptom control. Following transient improvement, her symptoms subsequently returned and failed to fully resolve in spite of increased voriconazole dosing and multiple additional tissue debridements over the course of many years. CONCLUSIONS: Invasive upper airway aspergillosis is exceedingly uncommon in immunocompetent patients. In the rare instances that such infections do occur, combinatorial voriconazole and endoscopic debridement is typically an efficacious treatment approach. However, some patients may continue to experience refractory symptoms. In such cases, continued aggressive treatment may potentially slow disease progression even if complete disease resolution cannot be achieved.

RESUMO

Asthma is a common disease in paediatrics and adults with a significant morbidity, mortality, and financial burden worldwide. Asthma is now recognized as a heterogeneous disease and emerging clinical and laboratory research has elucidated understanding of asthma's underlying immunology. The future of asthma is classifying asthma by endotype through connecting discernible characteristics with immunological mechanisms. This comprehensive review of the immunology of asthma details the currently known pathophysiology and clinical practice biomarkers in addition to forefront biologic and targeted therapies for all of the asthma endotypes. By understanding the immunology of asthma, practitioners will be able to diagnose patients by asthma endotype and provide personalized, biomarker-driven treatments to effectively control patients' asthma.

RESUMO

BACKGROUND: Critically ill patients with coronavirus disease-2019 (COVID-19) are at the theoretical risk of invasive pulmonary aspergillosis (IPA) due to known risk factors. PATIENTS/METHODS: We aimed to describe the clinical features of COVID-19-associated pulmonary aspergillosis at a single centre in New York City. We performed a retrospective chart review of all patients with COVID-19 with Aspergillus isolated from respiratory cultures. RESULTS: A total of seven patients with COVID-19 who had one or more positive respiratory cultures for Aspergillus fumigatus were identified, all of whom were mechanically ventilated in the ICU. Four patients were classified as putative IPA. The median age was 79 years, and all patients were male. The patients had been mechanically ventilated for a mean of 6.8 days (range: 1-14 days) before Aspergillus isolation. Serum galactomannan level was positive for only one patient. The majority of our cases received much higher doses of glucocorticoids than the dosage with a proven mortality benefit. All four patients died. CONCLUSIONS: Vigilance for secondary fungal infections will be needed to reduce adverse outcomes in critically ill patients with COVID-19.

RESUMO

Coronavirus disease 2019 (COVID-19), caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has been sweeping across the globe. Based on a retrospective analysis of SARS and influenza data from China and worldwide, we surmise that the fungal co-infections associated with global COVID-19 might be missed or misdiagnosed. Although there are few publications, COVID-19 patients, especially severely ill or immunocompromised, have a higher probability of suffering from invasive mycoses. Aspergillus and Candida infections in COVID-19 patients will require early detection by a comprehensive diagnostic intervention (histopathology, direct microscopic examination, culture, (1,3)-ß-D-glucan, galactomannan, and PCR-based assays) to ensure effective treatments. We suggest it is prudent to assess the risk factors, the types of invasive mycosis, the strengths and limitations of diagnostic methods, clinical settings, and the need for standard or individualized treatment in COVID-19 patients. We provide a clinical flow diagram to assist the clinicians and laboratory experts in the management of aspergillosis, candidiasis, mucormycosis, or cryptococcosis as co-morbidities in COVID-19 patients.

RESUMO

With the current revived interest in the use of bacteriophages for the treatment of bacterial infections, the study of mycoviruses as novel therapeutic solutions for invasive aspergillosis is the logical next step. Although ssRNA, dsRNA, and ssDNA mycoviruses have been identified, the majority of characterised mycoviruses have dsRNA genomes. Prevalence of dsRNA mycoviruses in Aspergillus spp. varies, and mycoviruses can have different effects on their fungal hosts: hypovirulence, hypervirulence, or a killer phenotype. Therapeutically, extracellular transmission of the mycovirus is essential. DsRNA mycoviruses lack an extracellular phase; however, a single ssDNA mycovirus with homologues in Aspergillus genomes has been described with an extracellular mode of transmission. Mycoviruses can induce hypovirulence or a killer phenotype, and both can be exploited therapeutically. Mycoviruses inducing hypovirulence have been used to control chestnut blight, however for aspergillosis no such mycovirus has been identified yet. Mycovirus encoded killer toxins or anti-idiotypic antibodies and killer peptides derived from these have been demonstrated to control fungal infections including aspergillosis in animals. This indicates that mycoviruses inducing both phenotypes could be exploited therapeutically as long as the right mycovirus has been identified.

RESUMO

PURPOSE OF REVIEW: Bacterial super-infection of critically ill influenza patients is well known, but in recent years, more and more reports describe invasive aspergillosis as a frequent complication as well. This review summarizes the available literature on the association of invasive pulmonary aspergillosis (IPA) with severe influenza [influenza-associated aspergillosis (IAA)], including epidemiology, diagnostic approaches and treatment options. RECENT FINDINGS: Though IPA typically develops in immunodeficient patients, non-classically immunocompromised patients such as critically ill influenza patients are at high-risk for IPA as well. The morbidity and mortality of IPA in these patients is high, and in the majority of them, the onset occurs early after ICU admission. At present, standard of care (SOC) consists of close follow-up of these critically ill influenza patients with high diagnostic awareness for IPA. As soon as there is clinical, mycological or radiological suspicion for IAA, antifungal azole-based therapy (e.g. voriconazole) is initiated, in combination with therapeutic drug monitoring (TDM). Antifungal treatment regimens should reflect local epidemiology of azole-resistant Aspergillus species and should be adjusted to clinical evolution. TDM is necessary as azoles like voriconazole are characterized by nonlinear pharmacokinetics, especially in critically ill patients. SUMMARY: In light of the frequency, morbidity and mortality associated with influenza-associated aspergillosis in the ICU, a high awareness of the diagnosis and prompt initiation of antifungal therapy is required. Further studies are needed to evaluate the incidence of IAA in a prospective multicentric manner, to elucidate contributing host-derived factors to the pathogenesis of this super-infection, to further delineate the population at risk, and to identify the preferred diagnostic and management strategy, and also the role of prophylaxis.

RESUMO

INTRODUCTION: Severe fever with thrombocytopenia syndrome (SFTS) has been prevalent in parts of Asia during recent years. However, SFTS with invasive pulmonary aspergillosis (IPA) is rare, and it is important to understand its clinical features. MATERIALS AND METHODS: Total four cases of SFTS with IPA are reviewed and detailing the disease progression, treatment options, and prognosis were summarized and analyzed. RESULTS: The patients with SFTS-associated IPA first presented with fever, gastrointestinal symptoms, thrombocytopenia, leukopenia, and multiple organ failure. After 1-2 weeks, the patients developed mild polypnea and wheezing rales, and quickly developed dyspnea and respiratory failure. Tracheal intubation was usually performed, but did not relieve the intractable airway spasm and pulmonary ventilation failure. Bronchoscopy confirmed that the antifungal treatment was ineffective and the aspergillosis had worsened. All patients died of type 2 respiratory failure caused by continued airway obstruction and spasticity. CONCLUSIONS: Given the high mortality rate in this series, there is a need for increased awareness of SFTS-associated IPA. Additional examinations should be performed in these cases, and early-stage antifungal treatment with organ support may be helpful.

RESUMO

PURPOSE OF REVIEW: Invasive fungal disease (IFD) is a cause of morbidity and mortality in allogeneic hematopoietic stem cell transplant (HSCT) recipients. As more potent broad-spectrum antifungal agents are used in prophylaxis, drug resistance and less common fungal species have increased in frequency. Here we review current treatments available for IFD and examine the potential for adoptive T-cell treatment to enhance current therapeutic choices in IFD. RECENT FINDINGS: There is growing evidence supporting the role of T cells as well as phagocytes in antifungal immunity. T cells recognizing specific antigens expressed on fungal morphotypes have been identified and the role of T-cell transfer has been explored in animal models. The clinical efficacy of adoptive transfer of antigen-specific T cells for prophylaxis and treatment of viral infections post-HSCT has raised interest in developing good manufacturing practice (GMP)-compliant methods for manufacturing and testing fungus-specific T cells after HSCT. SUMMARY: As the outcomes of IFD post-HSCT are poor, reconstitution of antifungal immunity offers a way to correct the underlying deficiency that has caused the infection rather than simply pharmacologically suppress fungal growth. The clinical development of fungus specific T cells is in its early stages and clinical trials are needed in order to evaluate safety and efficacy.

RESUMO

Inflammatory bowel disease patients at risk of opportunistic infections are those treated with immunomodulators. Toruner and colleagues found that corticosteroid use was more commonly associated with fungal infections. We present a case of invasive pulmonary Aspergillosis due to corticosteroid therapy in the context of a severe Ulcerative Colitis flare. We want to highlight the relationship between Aspergillus fumigatus and horses; and the use of leucocitapheresis combined with mesalazine as an effective treatment option in this patients who can not take more immunosuppressive therapy.

RESUMO

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.

RESUMO

INTRODUCTION: The incidence of invasive pulmonary aspergillosis (IPA) in intensive care unit (ICU) patients is increasing, and early diagnosis of the disease and treatment with antifungal drugs is critical for patient survival. Serum biomarker tests for IPA typically give false-negative results in non-neutropenic patients, and galactomannan (GM) detection, the preferred diagnostic test for IPA using bronchoalveolar lavage (BAL), is often not readily available. Novel approaches to IPA detection in ICU patients are needed. In this multicenter study, we evaluated the performance of an Aspergillus lateral-flow device (LFD) test for BAL IPA detection in critically ill patients. METHODS: A total of 149 BAL samples from 133 ICU patients were included in this semiprospective study. Participating centers were the medical university hospitals of Graz, Vienna and Innsbruck in Austria and the University Hospital of Mannheim, Germany. Fungal infections were classified according to modified European Organization for Research and Treatment of Cancer/Mycoses Study Group criteria. RESULTS: Two patients (four BALs) had proven IPA, fourteen patients (sixteen BALs) had probable IPA, twenty patients (twenty-one BALs) had possible IPA and ninety-seven patients (one hundred eight BALs) did not fulfill IPA criteria. Sensitivity, specificity, negative predictive value, positive predictive value and diagnostic odds ratios for diagnosing proven and probable IPA using LFD tests of BAL were 80%, 81%, 96%, 44% and 17.6, respectively. Fungal BAL culture exhibited a sensitivity of 50% and a specificity of 85%. CONCLUSION: LFD tests of BAL showed promising results for IPA diagnosis in ICU patients. Furthermore, the LFD test can be performed easily and provides rapid results. Therefore, it may be a reliable alternative for IPA diagnosis in ICU patients if GM results are not rapidly available.

RESUMO

Aspergillus pulmonary infection causes a spectrum of diverse diseases according to host immunity. The two major entities are invasive pulmonary aspergillosis and chronic pulmonary aspergillosis. The later can be divided into aspergilloma, then into chronic cavitary, more or less fibrosing aspergillosis, and finally into chronic necrotizing aspergillosis, or semiinvasive aspergillosis. The present article reviews this complex classification, which is necessary to reflect the diverse clinical aspect of the disease. Allergic broncho-pulmonary aspergillosis (ABPA), which is more a hypersensitivity reaction than an infectious process, will not be discussed here.

RESUMO

BACKGROUND: Granulocyte transfusions (GTXs) have been used successfully as an adjunctive treatment option for invasive infections in some neutropenic patients with underlying hematologic malignancy (HM). PATIENTS AND METHODS: We sought to determine the impact of GTX as an adjunct to antifungal therapy in 128 patients with HM and prolonged neutropenia (≥14 days) with a proven or probable invasive aspergillosis (IA) infection by retrospectively reviewing our institutional database. RESULTS: Fifty-three patients received GTX and 75 did not. By univariate analysis, patients with invasive pulmonary aspergillosis who received GTX were less likely to respond to antifungal therapy (P = 0.03), and more likely to die of IA (P = 0.009) when compared with the non-GTX group. Among patients who received GTX, 53% developed a pulmonary reaction. Furthermore, IA-related death was associated with the number of GTX given (P = 0.018) and the early initiation of GTX within 7 days after starting antifungal therapy (P = 0.001). By multivariate competing risk analysis, patients who received GTX were more likely to die of IA than patients who did not receive GTX (P = 0.011). CONCLUSIONS: Our study suggests that GTX does not improve response to antifungal therapy and is associated with worse outcomes of IA infection in HM patients, particularly those with pulmonary involvement.

RESUMO

BACKGROUND AND OBJECTIVE: Hematopoietic stem cell transplant (HSCT) is a well-established treatment for hematologic malignancies and certain autoimmune and congenital conditions. HSCT is associated with immunocompromise and increased risk of infections. This study assessed whether invasive pulmonary aspergillosis (IPA) affects in-hospital mortality and 30-day readmission among HSCT patients. A secondary objective was to examine potential differences in complications between HSCT with and without IPA. MATERIALS AND METHODS: A retrospective study of a nationally representative cohort of hospital admissions was conducted, with data collected from the Agency for Healthcare Research and Quality's Healthcare Cost and Utilization Project Nationwide Readmissions Database between 2013 and 2019. The International Classification of Diseases, 10th revision (ICD-10), and 9th revision (ICD-9) diagnostic codes were used to identify patients with IPA and HSCT. All adult patients ≥18 years were included in the study. RESULTS: There were 90,451 hospitalizations for HSCT from 2013 to 2019; 89,331 (98.8%) had HSCT without IPA, while 1092 (1.2%) hospitalizations had HSCT with IPA. The in-hospital mortality for HSCT-IPA was higher compared to HSCT without IPA (18.3% vs. 4.2%; p < 0.001). HSCT-IPA had a significantly higher 30-day readmission rate (36.2%) than that of HSCT without IPA (24.0%). HSCT-IPA also had a higher mean cost of admission ($303,437) than that of HSCT without IPA ($57,587).The HSCT-IPA group had higher multi-organ complications, including respiratory failure (51.3% vs. 13.5%, p < 0.001), sepsis (38.2% vs. 18.5%, p < 0.001), septic shock (16.1% vs. 5.1%, p < 0.001), need for mechanical ventilation (21.1% vs. 5.1% p < 0.001), non-invasive positive pressure ventilation (4.9% vs. 2.5%, p < 0.001), and intensive-care unit admission (21.8% vs. 6.1% p < 0.001). CONCLUSION: IPA is a rare but severe complication associated with HSCT, with higher in-hospital mortality, complications due to multi-organ failure, readmission rates, and cost of hospitalization when compared to HSCT without IPA.

RESUMO

We reviewed 776 patients who were culture positive for Aspergillus species at the hospital from 2000 to 2009. The isolates were collected for species identification by oligonucleotide hybridization and sequence analysis. A total of 96 cases of proven or probable IA were identified according to published criteria. The incidence of IA has increased significantly during the study period. Aspergillus fumigatus and A. flavus (41.7% each) were equally prevalent causative species. IA due to unusual species including A. nidulans (n=2), A. versicolor (n=2), and A. tubingensis (n=1) were also found. Among patients with IA, 55.2% had hematological disorder, 19.8% had underlying lung disorder, and 10.4% had autoimmune disease. The isolates species (P<0.001) and underlying disease (P<0.001) significantly affect the association of a positive culture with invasive disease. The overall mortality at three months was 62.5%, which remained stable throughout the study period. Multivariate analysis identified prior steroid use (P=0.007) as a significant risk factor for death, while surgery (P=0.030) and voriconazole (P=0.012) had protective effects. In conclusion, autoimmune disorders and underlying pulmonary diseases should also be considered as important predisposing factors of IA. Further emphasis on surgery and voriconazole in the management of IA might be beneficial.
