- Itraconazole Serum Trough Concentrations Using Oral Capsules for the Treatment of Chronic Pulmonary Aspergillosis: What is the Target?(2023) OLIVEIRA, Vitor Falcao de; TABORDA, Mariane; ARCIERI, Vitor Ciampone; KRUSCHEWSKY, Wdson Luis Lima; COSTA, Andre Nathan; DUARTE, Nilo Jose Coelho; ROMANO, Paschoalina; EBNER, Persio de Almeida Rezende; MAGRI, Adriana Satie Goncalves Kono; ABDALA, Edson; LEVIN, Anna S. S.; MAGRI, Marcello Mihailenko ChavesBackgroundIn regions where there is only itraconazole capsule as a therapeutic option for treatment of chronic pulmonary aspergillosis (CPA), measuring the serum concentrations becomes even more important for therapeutic success.ObjectiveEvaluate the initial itraconazole serum trough concentrations after the administration of oral capsule of itraconazole for the treatment of CPA.MethodsThe measurement was performed at least 7-days after initiation of therapy. The standard treatment at our institution was a 200 mg capsule every 12 h. We defined that an adequate serum trough concentration of itraconazole during treatment was 1-4 mg/L.ResultsThis study recruited 28 patients. The median value was 0.30 mg/L (IQR 0.01-0.70). Only 11% (n = 3) had adequate serum concentrations based on guideline recommendation. All patients with clinical deterioration had itraconazole serum levels <= 0.8 mg/L.ConclusionThe initial serum concentrations of itraconazole after capsule formulation administration were low. Increasing the dose should be considered when the itraconazole concentration is low, especially if it is <= 0.8 mg/L, and the patient presents with clinical deterioration. Larger studies are needed to evaluate the adequate concentrations recommended for CPA.
- Sensitivity of Antigen, Serology, and Microbiology Assays for Diagnosis of the Subtypes of Chronic Pulmonary Aspergillosis at a Teaching Hospital in Sao Paulo, Brazil(2023) OLIVEIRA, Vitor Falcao de; VIANA, Joshua Araujo; SAWAMURA, Marcio Valente Yamada; MAGRI, Adriana Satie Goncalves Kono; COSTA, Andre Nathan; ABDALA, Edson; MARIANI, Alessandro Wasum; BENARD, Gil; MAGRI, Marcello Mihailenko ChavesChronic pulmonary aspergillosis (CPA) is divided into five subtypes. The diagnosis of CPA is complicated due to poor sensitivity of the laboratory tests. Diagnostic performance of different antigen, serological, and microbiologi-cal methods in subtypes of CPA is unknown. The purpose of this study was to evaluate the diagnostic performance in different subtypes of CPA. A total of 91 participants with CPA were included, and the study was performed at Hospital das Clinicas of University of Sao Paulo. Bronchoalveolar lavage galactomannan (73%, 11/15), serology by immunodiffu-sion test (81%, 61/75), and histology (78%, 39/50) had the best sensitivity. The counterimmunoelectrophoresis (CIE) titers had a significant statistical difference between the CPA subtypes (P < 0.001), in which the forms chronic fibrosing pulmonary aspergillosis (CFPA) and subacute invasive aspergillosis (SAIA) had higher titers: 1/64 (interquartile range [IQR]: 1/32-1/256) and 1/64 (1/32-1/128).C-reactive protein generally presented lower values (median 15 mg/L, IQR: 6-33), with higher values in SAIA and lower values for Aspergillus nodule. Overall, we found a low diagnostic sensitivity of current tests. Regarding the CPA subtypes, we did not find great differences in the performance of the tests, but it is observed that the inflammatory markers and CIE titers tend to be higher in forms of the more extensive lung parenchyma involvement, such as SAIA and CFPA.
- Bloodstream infection caused by extensively drug-resistant Acinetobacter baumannii in cancer patients: high mortality associated with delayed treatment rather than with the degree of neutropenia(2016) FREIRE, M. P.; GARCIA, D. de Oliveira; GARCIA, C. P.; BUENO, M. F. Campagnari; CAMARGO, C. H.; MAGRI, A. S. G. Kono; FRANCISCO, G. R.; REGHINI, R.; VIEIRA, M. F.; IBRAHIM, K. Y.; ROSSI, F.; HAJJAR, L.; LEVIN, A. S.; HOFF, P. M.; PIERROTTI, L. C.; ABDALA, E.This study aimed to describe severe infections with extensively drug-resistant Acinetobacter baumannii-calcoaceticus complex (XDR-ABC), as well as to investigate risk factors for mortality, in cancer patients. It was a retrospective study including all patients diagnosed with XDR-ABC bacteraemia during hospitalization in the intensive care unit of a cancer hospital between July 2009 and July 2013. Surveillance cultures were collected weekly during the study period, and clonality was analysed using pulsed field gel electrophoresis (PFGE). We analysed underlying diseases, oncology therapy, neutrophil counts, infection site and management of infection, in terms of their correlation with 30-day mortality. During the study period, 92 patients with XDR-ABC bacteraemia were identified, of whom 35 (38.0%) were patients with haematological malignancy. We identified XDR-ABC strains with four different profile patterns, 91.3% of patients harbouring the predominant PFGE type. Of the 92 patients with XDR-ABC bacteraemia, 66 (71.7%) had central line-associated bloodstream infections; infection occurred during neutropenia in 22 (23.9%); and 58 (63.0%) died before receiving the appropriate therapy. All patients were treated with polymyxin, which was used in combination therapy in 30 of them (32.4%). The 30-day mortality rate was 83.7%. Multivariate analysis revealed that septic shock at diagnosis of XDR-ABC infection was a risk factor for 30-day mortality; protective factors were receiving appropriate therapy and invasive device removal within the first 48 h. Among cancer patients, ineffective management of such infection increases the risk of death, more so than do features such as neutropenia and infection at the tumour site.
- Challenges, Characteristics, and Outcomes of Chronic Pulmonary Aspergillosis: A 11-Year Experience in A Middle-Income Country(2023) OLIVEIRA, Vitor Falcao de; VIANA, Joshua Araujo; SAWAMURA, Marcio Valente Yamada; MAGRI, Adriana Satie Goncalves Kono; BENARD, Gil; COSTA, Andre Nathan; ABDALA, Edson; MARIANI, Alessandro Wasum; MAGRI, Marcello Mihailenko ChavesObjectives Chronic pulmonary aspergillosis (CPA) is a research priority in fungal diseases with a need for new studies to reduce misdiagnosis with more common diseases, discuss improvement in diagnostic methods and better characterize gaps in antifungal and surgical treatments to improve clinical outcomes. Methods In this retrospective study, we reviewed medical records of patients diagnosed with CPA from January 2010 to June 2021 at University of Sao Paulo, Sao Paulo, Brazil. We evaluated clinical characteristics, radiological findings, serology, treatment, and outcomes. Results The study included 91 participants, with 43 (47.3%) patients who underwent surgery and 69 (75.8%) received antifungal therapy. We found a predominance of middle-aged adults (median 51 years), males (n = 58, 64%) with lower BMI (median 21.3 kg/m(2)). The most common underlying lung disease was pulmonary tuberculosis (n = 70, 76.9%). The commonest symptoms were cough (n = 67, 74%), haemoptysis, and dyspnea (n = 63, 70%). The most common chest computerized tomography abnormalities were cavity (n = 86, 94.5%), with a predominance of mycetomas (n = 78, 91%). The serology was positive in 81% (61/75). The one-year mortality was low (3.3%). Clinical improvement and stability occurred in 89% of participants for constitucional symptoms and 86% for pulmonary symptoms. While serological improvement and stability occurred in 71%. Radiological improvement and stability occurred in 75%. Conclusion We observed a good outcome after 1-year follow-up, in which the majority had improvement or stability of pulmonary and constitutional symptoms, decrease in CIE titers and low mortality.
