Fusariosis in cancer patients: 13 case series report and literature review / Fusariosis en pacientes con cáncer: serie de 13 casos y revisión de la literatura

The fusariosis is an opportunistic mycosis caused by Fusarium spp. Its clinical presentation depends on the immunological status of the host, especially in patients with hematooncological diseases, whose manifestations vary from localized to invasive fungal infections. Skin or blood culture helps to guide combined antifungal treatment with amphotericin B and voriconazole. Here, we present 13 cases in a period of eleven years of patients with cancer who developed disseminated fusariosis and their outcomes, together with a review of the related literature. In this series of cases, mortality was 61.5 % (8/13), despite the use of the antifungal. Out of the 13 cases, 11 had hematological neoplasia and 2 solid neoplasia. The most determinant risk factor was profound neutropenia. Skin involvement and positive blood cultures in most cases allowed combined treatment prescription. Persistent febrile neutropenia associated with skin lesions, onychomycosis, nodules, or lung masses lead to suspicion of Fusarium spp. fungal invasive infection. The aim of this series of cases is to remind healthcare professionals that oncological patients with deep and persistent febrile neutropenia can develop fusariosis.

La fusariosis es una micosis oportunista producida por Fusarium spp. Su presentación clínica depende del estado inmunológico del huésped, especialmente, el de aquellos con enfermedades hematooncológicas, cuyas manifestaciones varían desde formas localizadas hasta infección fúngica invasora. El cultivo de piel o de sangre permite orientar el tratamiento antifúngico combinado con anfotericina B y voriconazol. Se presentan 13 casos de pacientes con cáncer en un periodo de once años que desarrollaron fusariosis diseminada; asimismo, se hizo con una revisión extensa de la literatura. En esta serie de casos, la mortalidad fue del 61,5 % (8/13), a pesar del uso del antifúngico. De los 13 pacientes, 11 tenían neoplasia hematológica y 2 neoplasia sólida. El factor de riesgo más importante fue la neutropenia profunda. El compromiso de la piel y los hemocultivos positivos facilitaron la prescripción del tratamiento combinado en la mayoría de los casos. La neutropenia febril persistente asociada a lesiones cutáneas, la onicomicosis, los nódulos o las masas pulmonares permitieron sospechar una infección fúngica invasora por Fusarium spp. El objetivo de la presentación de esta serie de casos es recordar el diagnóstico de fusariosis a la comunidad médica en contacto con pacientes oncológicos, con neutropenia febril profunda y persistentes.

Associated factors for mortality in a COVID-19 colombian cohort: is the third wave relevant when Mu variant was predominant epidemiologically?

OBJECTIVES: To evaluate the association between Colombia's third wave when the Mu variant was predominant epidemiologically (until 75%) in Colombia and COVID-19 all-cause in-hospital mortality. METHODS: In this retrospective cohort, we included hospitalized patients ≥18 years with SARS-CoV-2 infection between March 2020 to September 2021 in ten hospitals from three cities in Colombia. Description analysis, survival, and multivariate Cox regression analyses were performed to evaluate the association between the third epidemic wave and in-hospital mortality. RESULTS: A total of 25,371 patients were included. The age-stratified time-to-mortality curves showed differences according to epidemic waves in patients ≥75 years (log-rank test p = 0.012). In the multivariate Cox analysis, the third wave was not associated with increased mortality relative to the first wave (aHR 0.95; 95%CI 0.84-1.08), but there was an interaction between age ≥75 years and the third wave finding a lower HR for mortality (aHR 0.56, 95%CI 0.36-0.86). CONCLUSIONS: We did not find an increase in in-hospital mortality during the third epidemic wave in which the Mu variant was predominant in Colombia. The reduced hazard in mortality in patients ≥75 years hospitalized in the third wave could be explained by the high coverage of SARS-CoV-2 vaccination in this population and patients with underlying conditions.

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. One hundred five patients with a mean age of 48 years (SD 19.0) were identified, 45% with acute leukemia and 37% with lymphomas. In 42%, the HM was relapsed/refractory, 82% ECOG > 3, and 35% received antifungal prophylaxis; 57% were in neutropenia, with an average duration of 21.8 days. In 86 (82%) patients, Candida spp. was identified, and other yeasts in 18%. The most frequent of the isolates were non-albicans Candida (61%), C. tropicalis (28%), C. parapsilosis (17%), and C. krusei (12%). The overall 30-day mortality was 50%. The survival probability at day 30 in patients with leukemia vs. lymphoma/multiple myeloma (MM0 group was 59% (95% CI 46-76) and 41% (95% CI 29-58), p = 0.03, respectively. Patients with lymphoma or MM (HR 1.72; 95% CI 0.58-2.03) and ICU admission (HR 3.08; 95% CI 1.12-3.74) were associated with mortality. In conclusion, in patients with HM, non-albicans Candida species are the most frequent, and high mortality was identified; moreover, lymphoma or MM and ICU admission were predictors of mortality.

[Inappropriate antifungal prescription and the need for antifungal stewardship programs]. / Prescripción inapropiada de antifúngicos y la necesidad de programas para su uso racional.

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. Some groups have recommended many interventions to control and make a rational use of antimicrobials, into strategies known as "antimicrobial stewardship", these interventions are useful also for antifungal agents and it has been named "antifungal stewardship". Here we present a narrative review of the scientific literature showing published articles about appropriate use of antifungal agents and the experience of some centers after implementing antifungal stewardship programs.

Prescripción inapropiada de antifúngicos y la necesidad de programas para su uso racional / Inappropriate antifungal prescription and the need for antifungal stewardship programs

Resumen La enfermedad fúngica invasora (EFI) es una entidad que afecta pacientes inmunocomprometidos y críticamente enfermos. En los últimos años, el número de pacientes con riesgo de presentarla viene en aumento, con el consecuente incremento de la formulación de antifúngicos de manera profiláctica, anticipada o empírica. Algunos estudios que evaluaron el uso adecuado de antifúngicos han mostrado que hasta 72% de las formulaciones pueden ser inapropiadas, exponiendo a los pacientes al riesgo de efectos adversos e interacciones medicamentosas, con mayores costos de la atención. Se han recomendado diferentes intervenciones para el control y el uso racional de antimicrobianos, conocidas como "antimicrobial stewardship", las que se pueden aplicar al uso de antifúngicos denominándose "antifungal stewardship"". Se presenta una revisión de la literatura médica sobre el uso apropiado de antifúngicos y el impacto de la implementación de programas de optimización del uso de estos medicamentos en algunos centros.
