Application and evaluation of topical amphotericin B for the treatment of respiratory fungal infections.

BACKGROUND: In recent years, the prevalence of respiratory fungal diseases has increased. Polyene antifungal drugs play a pivotal role in the treatment of these conditions, with amphotericin B (AmB) being the most representative drug. This study aimed to evaluate the efficacy and safety of topical administration of AmB in the treatment of respiratory fungal infections. METHODS: We conducted a retrospective study on hospitalized patients treated with topical administered AmB for respiratory fungal infections from January 2014 to June 2023. RESULTS: Data from 36 patients with invasive pulmonary fungal infections treated with topical administration of AmB were collected and analyzed. Nebulization was administered to 27 patients. After the treatment, 17 patients evidenced improved conditions, whereas 10 patients did not respond and died in the hospital. One patient experienced an irritating cough as an adverse reaction. Seven patients underwent tracheoscopic instillation, and two received intrapleural irrigation; they achieved good clinical therapeutic efficacy without adverse effects. CONCLUSION: The combined application of systemic antifungal treatment and topical administration of AmB yielded good therapeutic efficacy and was well-tolerated by the patients. Close monitoring of routine blood tests, liver and kidney function, and levels of electrolytes, troponin, and B-type natriuretic peptide supported this conclusion.

[Tomography guided biopsy for the diagnosis of pediatric pulmonary Cryptococcosis]. / Punción Biopsia guiada por tomografía para el diagnóstico de Cryptococcosis pulmonar pediátrica.

Pulmonary cryptococcosis is a lung infection caused by the Cryptococcus yeast. It is rare in pediatrics, especially in immunocompetent children. The diagnosis of pulmonary cryptococcosis can be challenging due to the low specificity of symptoms, low index of suspicion, and limited diagnostic resources. OBJECTIVE: To describe a clinical case of pulmonary cryptococcosis in an immunocompetent adolescent, detailing the diagnostic approach. CLINICAL CASE: A 15-year-old patient, previously healthy, from a rural town, who consulted due to cough and a 1-month rib stitch pain, without fever or associated respiratory difficulty, with two images of condensation in the left lung on the chest x-ray. In the Computed Tomography, the images showed a nodular appearance. Due to suspicion of neoplastic pathology, a Positron Emission Tomography was performed, which showed hypermetabolic nodular lesions. The tomographic characteristics could correspond to fungal or granulomatous involvement. Considering the images and epidemiological risk factors such as rural origin and contact with bird droppings, the possibility of a mycosis was considered. A lung needle biopsy was performed under tomographic guidance. Cryptococcus neoformans was identified in the microbiology laboratory culture. The patient received treatment with itraconazole and fluconazole with good clinical and imaging response after 10 months of therapy and follow-up. CONCLUSION: In immunocompetent patients with a nonspecific clinical presentation, images can guide the diagnosis of pulmonary cryptococcosis, and an etiological search is essential to confirm it. In our case, the CT-guided needle biopsy was of great diagnostic utility.

Pulmonary histoplasmosis on the Chinese mainland: two case reports and literature review.

INTRODUCTION: Pulmonary histoplasmosis is a fungal disease that is endemic in North and Central America. It is relatively rare in China and commonly misdiagnosed as tuberculosis or cancer due to nonspecific clinical and radiographic manifestations. Rapid and accurate pathogen tests are critical for the diagnosis of pulmonary histoplasmosis. METHODOLOGY: We report two cases of pulmonary histoplasmosis. We collected all the relevant case reports on the Chinese mainland (from 1990 to 2022) to analyze features of this disease among Chinese patients. RESULTS: A total of 42 articles reporting 101 cases were identified, and the two cases reported in this article were also included for analysis. Sixty-three (61.2%) patients had respiratory symptoms and 35 (34.0%) patients were asymptomatic. The most common radiographic findings were pulmonary nodules or masses (81.6%). Twenty-two (21.4%) patients were misdiagnosed as tuberculosis, and 37 (35.9%) were misdiagnosed as lung tumors before pathological findings. Metagenomic next­generation sequencing (mNGS) testing provided a rapid diagnostic and therapeutic basis for three patients. CONCLUSIONS: Clinical features and imaging findings of pulmonary histoplasmosis are not specific. Relevant epidemiological history and timely pathogen detection are important for diagnosis. mNGS can shorten the time required for diagnosis and allow earlier initiation of targeted antibiotic therapy.

Hormographiella aspergillata pulmonary infections: Detection and identification of the fungus using pan-fungal PCR assays and DNA sequencing.

Hormographiella aspergillata is a basidiomycete exceptionally involved in invasive fungal infections (IFI). We report a case of H. aspergillata pulmonary infection in a 30-year-old female in a context of pancytopenia and relapsed of acute myeloid leukemia (AML). She presented with fever, thoracic pain, left pleural effusion and pneumonia, diagnosed on chest X-ray and CT-scan. Direct examination of a bronchoalveolar lavage (BAL) specimen performed on day (d) 10 was negative, while the culture was positive on d30. H. aspergillata was suspected, considering macroscopic and microscopic examination. Its identification was confirmed using Microflex® Bruker mass spectrometry and pan-fungal (PF)-PCR assay followed by DNA sequencing. After this initial diagnosis, the patient was monitored for 2.8 years. She was treated with liposomal amphotericin B and/or voriconazole until switching to isavuconazole on d298 due to side-effects. This antifungal treatment was maintained until d717 and then discontinued, the patient being considered as cured. Over this follow-up period, the patient was submitted to recurrent pulmonary sampling. Each time, cultures were negative, while PF - PCR assays and DNA sequencing confirmed the presence of H. aspergillata. The present case-report is the 32nd observation of H. aspergillata invasive infection showing that this IFI is still infrequent. Fifteen have occurred in patients with AML, which appears as the most frequent underlying disease favoring this IFI. Six recent case-reports in addition to ours highlight PF-PCR assays and DNA sequencing as relevant diagnostic tools that must be included in routine diagnosis and monitoring of IFI, specifically those due to rare basidiomycetes.

Breakthrough Invasive Sinusitis by Hormographiella aspergillata in a Neutropenic Patient Receiving Voriconazole Therapy: A Case Report and Review of Breakthrough H. aspergillata Infections.

Breakthrough invasive infections occurs during the use of antifungals both in prophylaxis and therapy, it favors the emergence of new pathogens in the fungal landscape. Hormographiella aspergillata is considered a rare but emerging pathogen in the era of broad-spectrum antifungal use in patients with hematological malignancies. Here, we present a case report of invasive sinusitis due to Hormographiella aspergillata, manifesting as a breakthrough infection in a patient with severe aplastic anemia under treatment with voriconazole for invasive pulmonary aspergilosis. Also, we make a review of H. aspergillata breakthrough infections published in the literature.

Pulmonary infection of Schizophyllum commune diagnosed by metagenomic next- generation sequencing: A case report.

RATIONALE: Fungal infection is common and difficult to be diagnosed timely in clinical, for its various kinds and similar manifestations. The rare pulmonary fungal infection such as Schizophyllum commune was one of the harder ones and misdiagnosed in usual. PATIENT CONCERNS: We report a 32-year-old female which was diagnosed with Metagenomic Next-Generation Sequencing (mNGS). She was hospitalized with the complaint of 4 months and more of repeated cough and expectorating. The chest computer tomography revealed left lower lobe pathological changes, but antibiotics were ineffective. No positive results were found in laboratory tests, including sputum culture and the pathology of lung puncture biopsy. DIAGNOSES: mNGS of lung biopsy was performed and detected the sequence number of Schizophyllum for 11. INTERVENTIONS: The patient was treated with voriconazole and itraconazole successively. OUTCOMES: She recovered to health. There was no recurrence during follow-up. LESSONS: mNGS as a diagnostic method could quickly detect pathogens through the processing of fragment, synthesis, comparison, and analysis of sample genes. It is suitable for detecting especially rare and polymicrobial infections. To our best knowledge, infection of Schizophyllum commune have not been reported in English literature with diagnostic method of mNGS.

Lesion size as a prognostic factor in the antifungal treatment of pulmonary cryptococcosis: a retrospective study with chest CT pictorial review of 2-year follow up.

BACKGROUND: Pulmonary cryptococcosis (PC) is a fungal infection that can have a variable prognosis depending on several factors. The objective of this study was to analyse the characteristics of pulmonary lesions and identify prognostic factors in patients with PC who were human immunodeficiency virus (HIV) -negative and underwent antifungal treatment. METHODS: The study enrolled patients diagnosed with PC who were negative for HIV. Symptoms, CT characteristics of pulmonary lesions, serum cryptococcal capsular antigen (CrAg) titre, underlying diseases, and duration of antifungal treatment were evaluated over a 2-year follow-up. RESULTS: A total of 63 patients (40 men and 23 women) with a mean age of 50.4 years were included. Half of the patients (50.8%) were asymptomatic, and the most common symptoms were cough (44.4%), expectoration (27.0%), and fever (17.5%). Pulmonary lesions were mainly present in the peripheral and lower lobes of the lung, with 35 cases classified as nodular-type lesions and 28 cases classified as mass-type lesions. At the first, third, sixth, 12th, and 24th-month follow-ups, the median proportion of residual pulmonary lesions were 59.6%, 29.9%, 12.2%, 9.6%, and 0.0%, respectively. During antifungal treatment, the lesions of 33 patients achieved complete response, while the remaining 30 patients did not. Compared with the non-CR group, the CR group had a lower baseline serum CrAg titre (median, 1:20 vs 1:80, P < 0.01), smaller pulmonary lesion size (median area, 1.6 cm2 vs 6.3 cm2, P < 0.01), lower Hounsfield-units (HU) radiodensity (median, - 60.0 HU vs - 28.5 HU, P < 0.05), more nodular-type lesions (72.7% vs 36.7%, P < 0.01), and fewer air-bronchogram signs (18.2% vs 43.3%, P < 0.05). Multivariate logistic regression analysis showed that a larger lesion size on chest CT scans was associated with a lower likelihood of achieving complete response [OR: 0.89; 95% CI (0.81-0.97); P < 0.05]. CONCLUSIONS: PC was more commonly observed in HIV-negative men, and chest CT scans mostly revealed nodular-type lesions. After antifungal treatment, patients with smaller lesions had a better prognosis.

Pulmonary scedosporiosis caused by Lomentospora prolificans in a patient who is immunocompetent: A rare case report.

Infections with Scedosporium and Lomentospora species are usually found in patients who are immunodeficient, particularly in the transplant population. However, they are relatively rare in patients who are immunocompetent, which is especially useful in ruling out near-drowning and aspiration situations. Here, we report a case of a patient who is immunocompetent, with clinically suspected community-acquired pneumonia caused by Lomentospora prolificans detected by metagenomics next-generation sequencing (mNGS) and polymerase chain reaction from bronchoalveolar lavage fluid. This case highlights mNGS in the clinical diagnosis of pulmonary invasive fungal disease. mNGS is proposed as an important adjunctive diagnostic approach for rare pathogens.

Pulmonary Cryptococcosis Diagnosed by a Transbronchial Lung Cryobiopsy in a Patient with Rheumatoid Arthritis.

A 77-year-old woman with seronegative rheumatoid arthritis who was being treated with prednisolone (8 mg/day) and methotrexate (12 mg/week) visited our hospital with an 11-day history of a fever and dyspnea. Chest computed tomography showed infiltration in the right lower lobe. A transbronchial lung cryobiopsy (TBLC) showed cryptococcal cells, and bronchoalveolar lavage fluid later showed growth of Cryptococcus neoformans. She was treated with amphotericin B and flucytosine for about four weeks, and the pulmonary shadows improved. The treatment was then changed to fluconazole as outpatient consolidation and maintenance therapy. A rare case of pulmonary cryptococcosis diagnosed by a TBLC is reported.

Progress and challenges in fungal lung disease in cystic fibrosis.

PURPOSE OF REVIEW: This review is an overview of the recent progress made for the diagnosis and understanding of fungal lung disease in people with cystic fibrosis (CF), with a focus on Aspergillus fumigatus , the most common filamentous fungus in the CF airway. Currently, the longstanding question of the clinical significance of Aspergillus fumigatus and other fungi in CF respiratory cultures, in the absence of allergy, remains. Clinical criteria and biomarkers are needed to classify fungal lung disease and determine who may warrant therapy. RECENT FINDINGS: Several retrospective and prospective studies have described the prevalence of A. fumigatus and other fungi in the CF lung and factors contributing to the changes in fungal epidemiology. Selective fungus culture testing for the detection of fungi in CF sputa has been well studied, yet a standardized fungus culture protocol has yet to be defined. Culture-independent molecular studies and other fungal diagnostic testing have been conducted in the CF population, leading to efforts to better understand the clinical role of these tests. Recent works have aimed to determine whether chronic A. fumigatus colonization is associated with lung disease progression measured by FEV 1 percentage predicted, structural lung disease, lung clearance index and respiratory quality-of-life. However, the existing knowledge gaps remain: definition of a fungal respiratory infection, the association between fungal infection and clinical outcomes, and indications for antifungal therapy. SUMMARY: Significant progress has been made for the detection and diagnosis of fungal lung disease. Yet, the role and impact of A. fumigatus and other fungal infections on respiratory health in people with CF remains to be determined.

Clinical Diagnosis, Treatment, and Laboratory Detection of 50 Cases of Pulmonary Cryptococcosis.

Objective: This study retrospectively analyzed the clinical diagnosis, treatment process, and laboratory test data of patients with pulmonary cryptococcosis to improve the understanding and diagnosis and treatment ability of the disease. Methods: Patients with pulmonary cryptococcosis diagnosed in the First Affiliated Hospital of Dalian Medical University from October 2003 to July 2021 were selected, and their medical records were consulted. The general data, clinical manifestations, laboratory examinations, imaging characteristics, diagnosis, and treatment methods were studied. The software SPSS 22 was used for statistical analysis. Results: A total of 50 patients with pulmonary cryptococcosis were included in the study. The ratio of male to female was 1 : 1. The average age was 53.56 ± 11.99 years with a range of 27-82 years. Grouping the patients by age, with 10 years as an age group, we found that 40-60 years was the high-incidence age group. Two patients (4%) had a history of bird contact, and 18 patients (36%) had at least one underlying conditions. Hypertension and cough were the most common underlying condition and clinical manifestation, respectively. The main admission diagnoses were lung shadow (19/50, 38%) and chest/lung mass (15/50, 30%). In the imaging findings, the most common type of lesions was nodule/nodule shadow (29/69, 42.03%). Lesion distribution in the lower lobe, single lobe, and right lung was more frequent than that in the upper lobe, multilobes, and left lung, respectively. Burr sign (12/43, 27.91%) was the most common concomitant sign. Pulmonary ventilatory defect was found in 7 cases. Laboratory test results were largely nonspecific. The pathological examination showed granuloma, with 47 cases (94%) confirmed by postoperative biopsy. Two cases (4%) were confirmed by serology. One case (2%) was diagnosed with Cryptococcus smear. 43 cases (86%) were treated with simple surgical resection, 6 cases (12%) were treated with antifungal drugs, and 1 case (2%) was transferred to another hospital for suspicion of pulmonary tuberculosis. Conclusions: Pulmonary cryptococcosis is more common in the middle-aged and elderly, and the clinical specificity is low. It can occur in people with normal or impaired immune function. The main clinical and imaging manifestation is cough and pulmonary nodules, which are very easy 5to be misdiagnosed. Surgical resection is the primary treatment.

A case of pulmonary histoplasmosis treated with voriconazole.

Histoplasmosis is an infection caused by the dimorphic fungus Histoplasma capsulatum. The lungs are the most common site of infection, especially in patients with immune deficiency. We report a case of 62-year-old male patient presented with cough for 3 months and had been taking immunosuppressive drugs for 10 years after heart transplantation. Chest CT scan showed multiple pulmonary nodules. Lung tissue biopsy specimen culture suggested fungal infection, and Histoplasma capsulatum was confirmed by next-generation sequencing (NGS) detection. The patient was diagnosed with pulmonary histoplasmosis. After administration of voriconazole for 46 days, the symptom of cough was markedly relieved and the lesions were partly absorbed. After 13 months of treatment, the lesions completely disappeared, and no significant side-effect of voriconazole was observed. To our knowledge, report of voriconazole as the treatment of histoplasmosis is rare, especially in non-endemic areas. Moreover, this case enriches our experience in the adjustment between immunosuppressive and antifungal agents in treating histoplasmosis.

Outcomes after lung resection in renal transplant patients with pulmonary mucormycosis.

BACKGROUND: Pulmonary mucormycosis has been associated with high mortality (reported up to 100%) in renal transplant recipients. METHODS: This was a retrospective analysis of renal transplant patients with pulmonary mucormycosis between April 2014 and March 2020, who underwent surgical resection of the affected lung along with liposomal amphotericin therapy. Patients with lower respiratory illness features underwent chest X-ray, high-resolution computed tomography of the chest, and those with suspicious findings underwent analysis of bronchioloalveolar fluid and transbronchial lung biopsy. Patients with histological or microbiological evidence of mucormycosis were started on liposomal Amphotericin B. Tacrolimus and mycophenolate mofetil were stopped at the time of diagnosis. RESULT: Ten patients underwent combined management, while five patients were managed medically. At last follow up, seven out of ten patients (70%) who underwent combined management and two of the five patients (40%) who were managed medically, had a mean survival of 28.86 months (sd = 15.71, median = 25) and 14.17 months (sd = 12.21, median = 18), respectively, post-diagnosis of pulmonary mucormycosis. CONCLUSION: Surgical resection combined with antifungals in the perioperative period and decreased immunosuppression may improve the outcomes in renal transplant patients with pulmonary mucormycosis.

Pulmonary Mucormycosis as the Leading Clinical Type of Mucormycosis in Western China.

The aim was to better understand the clinical characteristics of patients with mucormycosis in western China. We retrospectively investigated the clinical, laboratory, radiological and treatment profiles of mucormycosis patients during a 10-year period (2010-2019). As a result, 59 proven mucormycosis were enrolled in this study. It was found that 52.5% of patients had worse clinical outcomes. Pulmonary mucormycosis (PM) was the most common clinical manifestation. The most frequent risk factor was diabetes mellitus (38, 64.4%) for mucormycosis patients. Cough (43, 93.5%), fever (24, 52.2%) and hemoptysis/bloody phlegm (21, 45.7%) were the most common manifestations of PM. There were no differences in clinical manifestations, risk factors and laboratory tests between different clinical outcome groups (P>0.05). Lymph node enlargement (30, 65.2%), patchy shadows (28, 60.9%), cavitation (25, 53.3%) and bilateral lobe involvement (39, 84.8%) were the most common on chest CT. Nodule was more common in good outcome group (P <0.05). A total of 48 cases (81.4%) were confirmed by histopathological examination, 22 cases (37.3%) were confirmed by direct microscopy. PM patients were treated with amphotericin B/amphotericin B liposome or posaconazale had better clinical outcomes (P <0.05). In conclusion, PM was the most common clinical type of mucormycosis in China. Diabetes mellitus was the most common risk factor. PM has diverse imaging manifestations and was prone to bilateral lobes involvement. Early diagnosis and effective anti-mucor treatment contribute to successful treatment.

Pulmonary fungal ball due to Trichophyton successfully managed with oral itraconazole: a case report.

Pulmonary fungal balls are caused by long-term fungal infection of the lung. They are sometimes a complication of previous cavitary pulmonary tuberculosis. Pulmonary fungal balls caused by Trichophyton are extremely rare. A 65-year-old man who worked in a leather recycling factory was admitted because of a productive cough and shortness of breath. He had a history of tuberculosis with lung destruction. A chest radiograph showed an opacity surrounding an air lucency over the left lung field, and chest computed tomography showed a mass within a cavity, producing a ball-in-hole appearance, over the left upper lung lobe. Bronchoalveolar lavage was performed, and fungal culture of the lavage fluid yielded Trichophyton. After 6 months of treatment with oral itraconazole, the patient's general condition improved. This case emphasizes the importance of awareness of fungal infection within cavitary lesions of the lung and shows that Trichophyton may be the etiologic organism in such cases. Itraconazole is a recommended treatment of pulmonary fungal balls.

A 31-Year-Old Man With Seizures, Brain Lesion, and Lung Nodules.

CASE PRESENTATION: A 31-year-old man was admitted to our hospital with a recent history of generalized seizures. Three months earlier, he started with intermittent hemoptysis. CT scan showed a cavitary lung lesion in the upper segment of the right inferior lobe (RIL). Because of his job as a social worker in a high-risk population, he started treatment for Mycobacterium TB; however, the BAL culture result was negative. At the time of his current admission, he has continued taking rifampicin, isoniazid, pyrazinamide, and levofloxacin. He denied the use of any illicit drugs or alcohol. He had no history of smoking. One year earlier, he visited Southeast Asia, Oceania, and South Africa for several months. He reported a weight loss of 7 kg since then. Except for a recurrent oral candidiasis, he did not have a relevant medical history. His family history was notable for mother with lupus, and brother with sarcoidosis.

[Pulmonary mucormycosis after lung transplantation:3 cases report with literature review].

Objective: To report the risk factors, clinical characteristics and treatment courses of pulmonary mucormycosis after lung transplantation(LT). Methods: We included 3 cases with pulmonary mucormycosis after LT from March 2017 to July 2020 in the centre for lung transplantation of China-Japan Friendship Hospital. Twelve cases from Chinese and English literature from China National Knowledge Infrastructure (CNKI), China Biomedical Literature Service System and Pubmed Database from March 1980 to July 2020 were added. The risk factors, clinical characteristics and treatment courses of all cases were summarized and analyzed. Results: Pulmonary mucormycosis occurred in 1.06% (3/284) in our centre. A total of 15 cases with 12 cases from literature included 10 males and 5 females with a mean age of(47±20)years. Thirteen cases occurred after LT, and 2 cases occurred after heart-lung transplantation (HLT). Nine probable cases were diagnosed by positive isolation of the pathogen from bronchoalveolar lavage fluid or sputum. Three proven cases were diagnosed by transbronchial lung biopsy. Meanwhile, the other 3 proven cases diagnosed by CT-guided percutaneous lung biopsy, autopsy and surgical operation respectively. Ten cases (66.7%) were diagnosed with pulmonary mucormycosis within 90 days after lung transplantation. The mortality was as high as 46.67% (7/15), but if it occurred within 90 days, the mortality reached 70% (7/10). The average interval between transplantation and positive isolation of the pathogen was 112.3 (5-378) days. Conclusions: The clinical and radiographic features of pulmonary mucormycosis after LT were nonspecific. It had a high mortality, especially in those occurred within 90 days after LT. The combination of antifungal therapy and surgical resection may contribute to a better outcome of the disease.

A 66-Year-Old Woman With Progressive Dyspnea and Obstructive Pneumonia.

CASE PRESENTATION: A 66-year-old woman with a history of diabetes presented with an intermittent low-grade fever, cough, shortness of breath, and decreased activity tolerance over a 3-month period. She is a farmer, and denied a history of chronic pulmonary disease. Her only medical history was type 2 diabetes managed without medication. She denied smoking or tobacco use. She did not report any recent travel and denied having birds at home. Imaging at a local hospital showed left lower lobe atelectasis with a small pleural effusion. An infection with mucormycosis was diagnosed through transbronchial biopsy. The patient was given nebulized amphotericin B along with concurrent IV liposomal amphotericin B for a total of 15 days. She experienced no significant improvement in symptoms during therapy and, in fact, developed worsening, progressive dyspnea.
