Geotrichosis: fungemia in a patient with acute lymphoblastic leukemia.

Fungemia caused by Geotrichum spp. is rare and highly lethal. The Instituto Nacional de Cancerología in Bogotá reported just two cases: one in the period 2001-2007 and the other in 2012-2018.

Fungemia in Hospitalized Adult Patients with Hematological Malignancies: Epidemiology and Risk Factors.

Fungemia in hematologic malignancies (HM) has high mortality. This is a retrospective cohort of adult patients with HM and fungemia between 2012 and 2019 in institutions of Bogotá, Colombia. The epidemiological, clinical, and microbiological characteristics are described, and risk factors related to mortality are analyzed.

Molecular and Clinical Data of Antimicrobial Resistance in Microorganisms Producing Bacteremia in a Multicentric Cohort of Patients with Cancer in a Latin American Country.

Patients with cancer have a higher risk of severe bacterial infections. This study aims to determine the frequency, susceptibility profiles, and resistance genes of bacterial species involved in bacteremia, as well as risk factors associated with mortality in cancer patients in Colombia. In this prospective multicenter cohort study of adult patients with cancer and bacteremia, susceptibility testing was performed and selected resistance genes were identified.

Development and validation of a scoring system for predicting cancer patients at risk of extended-spectrum b-lactamase-producing Enterobacteriaceae infections.

Background: Extended-spectrum beta-lactamase producing Enterobacteriaceae (ESBL-PE) infections are frequent and highly impact cancer patients. We developed and validated a scoring system to identify cancer patients harboring ESBL-PE at the National Institute of Cancer of Colombia.

Methods: We retrospectively analyzed medical records of 1695 cancer patients.

[Inappropriate antifungal prescription and the need for antifungal stewardship programs].

Invasive fungal disease (IFD) is a condition affecting immunosuppressed and critically ill patients. Recently there has been an increase in the amount of patients at risk for IFD, which implies an increase in the prescription of antifungal agents as prophylactic, pre-emptive or empiric therapy. Some studies evaluating appropriateness of antifungal prescription have shown that inappropriate formulations reach 72%, exposing patients to side effects, pharmacological interactions and rising costs.

[Behavior of carbapenemase-producing Klebsiella pneumoniae cases in cancer patients at a third level hospital in Bogotá, D.C].

Introduction: The presence of carbapenemase-producing Enterobacteriaceae in hospitals is increasingly common. Patients with advanced cancer who require invasive means for diagnosis, treatment or palliative care, and the use of broad-spectrum antimicrobials to treat secondary infections show increased susceptibility to infections caused by these bacteria.

Objective: To report the behavior of carbapenemase-producing Klebsiella pneumoniae (CPKP) isolates at the Instituto Nacional de Cancerología in Bogotá between January 2010 and December 2012.

Análisis de Costo Efectividad de Estrategias de Tratamiento Antimicótico en Pacientes con Neutropenia Febril Persistente y Tratamiento Antibiótico de Amplio Espectro.

Objective: To assess cost-effectiveness of antifungal treatment on patients with persistent fever neutropenia: empiric antifungal therapy (EAT) vs. anticipated antifungal therapy (AAT).

Methods: A decision model was performed to evaluate the cost-effectiveness of antifungal treatment strategies in patients with febrile neutropenia not responding to a broad spectrum antibiotic treatment.
