ABSTRACT
The global morbidity of invasive fungal diseases (IFD) tends to increase, especially in immunocompromised people.Due to the atypical symptoms, unclear etiological mechanism, and emerging antifungal resistance, IFD challenge current clinical diagnosis and treatment.The World Health Organization (WHO) developed the first WHO fungal priority pathogens list in 2022.The most concerning fungal pathogens were listed and summarized to promote further understanding of the epidemiology of IFD and antifungal drug resistance.It is hoped to provide a basis for the prevention and interventions of IFD.
ABSTRACT
El síndrome destructivo de línea media es un grupo de enfermedades inflamatorias y tumorales destructivas del área centrofacial, entre las cuales la paracoccidioidomicosis es una de las etiologías a considerar en los países del trópico. La paracoccidioidomicosis es causada por hongos del género Paracoccidioides. Su forma de blastoconidia favorece la diseminación hematógena, afectando diversos tejidos como glándulas suprarrenales, tejido retículo-endotelial o mucosa oral, esta última donde puede manifestarse como un síndrome destructivo de línea media. Presentamos un caso de paracoccidioidomicosis con afección en cavidad oral, el cual debutó como un síndrome destructivo de línea media crónico, asociado a compromiso grave de la vía aérea que requirió manejo quirúrgico por riesgo de obstrucción y presentó mejoría con manejo antimicótico sistémico.
Summary Midline destructive disease is a group of severe and destructive inflammatory and tumor diseases of the midface area, among which paracoccidioidomycosis is one of the main etiologies in tropical countries. Paracoccidioidomycosis is an endemic mycosis caused by fungi of the genus Paracoccidioides. Its blastoconidia form favors hematogenous spread, affecting various tissues such as adrenal glands, reticulo-endothelial tissue, or oral mucosa, where it can manifest as a destructive midline syndrome. We present a case of paracoccidioidomycosis with affection in the oral cavity, which debuted as a chronic midline destructive disease with sever airway compromise that required surgical treatment for the risk of obstruction of the airway. The patient received systemic treatment with good response.
ABSTRACT
Invasive fungal disease (IFD) is a major infectious complication in patients with hematological malignancies. In this study, we examined 4889 courses of chemotherapy in patients with hematological diseases to establish a training dataset (n = 3500) by simple random sampling to develop a weighted risk score for proven or probable IFD through multivariate regression, which included the following variables: male patients, induction chemotherapy for newly diagnosed or relapsed disease, neutropenia, neutropenia longer than 10 days, hypoalbuminemia, central-venous catheter, and history of IFD. The patients were classified into three groups, which had low (0-10, ~1.2%), intermediate (11-15, 6.4%), and high risk ( > 15, 17.5%) of IFD. In the validation set (n = 1389), the IFD incidences of the groups were ~1.4%, 5.0%, and 21.4%. In addition, we demonstrated that antifungal prophylaxis offered no benefits in low-risk patients, whereas benefits were documented in intermediate (2.1% vs. 6.6%, P = 0.007) and high-risk patients (8.4% vs. 23.3%, P = 0.007). To make the risk score applicable for clinical settings, a pre-chemo risk score that deleted all unpredictable factors before chemotherapy was established, and it confirmed that anti-fungal prophylaxis was beneficial in patients with intermediate and high risk of IFD. In conclusion, an objective, weighted risk score for IFD was developed, and it may be useful in guiding antifungal prophylaxis.
ABSTRACT
Resumen Introducción: El incremento de la enfermedad fúngica invasora (EFI) en pacientes inmunocomprometidos ha conducido a la frecuente prescripción de fármacos altamente activos pero de elevado costo económico. Objetivo: Caracterizar el uso de antifúngicos, evaluar su indicación y determinar consumo y costos asociados. Métodos: Estudio descriptivo, retrospectivo, desde enero de 2015 a abril de 2016. Auditoría de prescripciones y revisión de fichas clínicas; cada prescripción se clasificó de acuerdo a si correspondía a una EFI posible, probable o probada. Se calcularon consumos y costos de tratamientos. Resultados: Se auditaron 152 prescripciones de antifúngicos en 79 pacientes. El costo total de los medicamentos antifúngicos fue de US$ 714.413. El 52,1% del gasto (US $ 372.319) correspondió a indicaciones en EFI probada, 10,7% (US $ 76.377) EFI probable, 0.8% (US $ 5.638) no-EFI, 12,2% (US $ 87.459) EFI posibles y 1,5% (US $ 10.896) EFI descartada y 22,6% (US$ 161.723) fue profilaxis. El mayor consumo fue en indicaciones relacionadas a EFI probada con un DOT probada de 10,54 días, siendo anfotericina B liposomal y voriconazol iv los fármacos con mayor consumo con un DOTprobada AnBL de 3,15 y DOT probada voriconazol iv de 3,01. Conclusiones: El consumo de medicamentos antifúngicos genera altos costos correspondiente al 12% del presupuesto total de farmacia de nuestra institución. El gasto se asoció principalmente a indicaciones en EFI probadas, voriconazol y anfotericina B liposomal los con mayor consumo, lo que sumado a su alto costo y días prolongados de terapia generan un gran impacto en el presupuesto.
Background: The increase of invasive fungal disease (IFD) in immunocompromised patients has led to the frequent prescription of highly active antifungal drugs but with a high economic cost. Aim: To characterize the use of antifungals drugs, evaluate its prescription and determine consumption and associated costs. Methods: Retrospective descriptive study from January 2015 to April 2016. Audit of prescriptions and review of clinical files. Each prescription was classified according to whether it corresponded to a possible, probable or proven invasive fungal disease (IFD). Consumptions and treatment costs were calculated. Results: 152 antifungal prescriptions were audited in 79 patients. The total cost of antifungal medications was US $ 714,413. 52.1% of the expenditure (US $ 372,319) corresponded to indications in proven IFD, 10.7% (US $ 76,377) probable IFD, 0.8% (US $ 5,638) non-IFI, 12.2% (US $ 87,459) IFD possible and 1.5% (US $ 10,896) non-IFD and 22.6% (US $ 161,723) was prophylaxis. The highest consumption was in indications related to IFD tested with a proven DOT of 10.54 days, with liposomal amphotericin B and iv voriconazole the drugs with the highest consumption with a DOT probable_AnBL of 3.15 and DOT proven voriconazole iv of 3.01. Conclusions: The consumption of antifungal drug medications generates high costs at 12% of the total pharmacy budget of our institution. The expense was associated mainly with the indications in IFI tested the voriconazole and amphotericin B liposomal with the highest consumption which added to its high cost and prolonged days of general therapy a big impact in the budget.
