RESUMO
INTRODUCTION: Infectious meningoencephalitis (IME) is a neurological emergency with a significant rate of morbidity and mortality. The Biofire FilmArray® meningitis/encephalitis (FAME) panel for testing in cerebrospinal fluid (CSF) has proven to be a valuable tool for the aetiological diagnosis of IME, facilitating targeted antimicrobial therapy. The aim is to determine the impact of the FAME panel on antimicrobial therapeutic decisions in patients with suspected IME in the first 24 hours of clinical assessment. PATIENTS AND METHODS: This is a descriptive observational study that comments on the clinical manifestations, the neuroimaging and paraclinical findings, and the antibiotic therapy of patients with suspected IME. An analysis was performed to determine the impact of FAME on antimicrobial therapy in the first 24 hours of the clinical assessment of patients. RESULTS: Altogether 44 patients were included. The average time required to obtain the result of the FAME panel for testing in CSF was nine hours, with 20.4% (9/44) of tests yielding positive results. Within 24 hours of clinical assessment, their outcome had an impact on antimicrobial treatment decisions in 75% (33/44) of cases. In patients with a high clinical suspicion of IME, the result of FAME made it possible to change the initial empirical therapy to a targeted therapy in 15% (3/20) of cases and to discontinue the initial empirical therapy in 35% (7/20) of the subjects. In patients with low clinical suspicion of IME, their result allowed 25% (6/24) to have their suspicion confirmed and they were started on targeted antibiotic therapy; in contrast, 70.8% (17/24) had their diagnosis ruled out and were not started on treatment. CONCLUSIONS: The result of the FAME panel for testing in CSF has a high impact on antimicrobial therapeutic decisions within 24 hours of clinical assessment. However, it must be interpreted with the clinical context, local epidemiology and other diagnostic studies.
TITLE: Experiencia con el Biofire FilmArray® para meningitis/encefalitis infecciosa en una institución de alta complejidad en Bogotá, Colombia.Introducción. La meningoencefalitis infecciosa (MEI) es una emergencia neurológica con importante morbimortalidad. El panel Biofire FilmArray? para meningitis/encefalitis (FAME) en el líquido cefalorraquídeo (LCR) ha demostrado ser una valiosa herramienta para el diagnóstico etiológico de la MEI, facilitando una terapia antimicrobiana dirigida. El objetivo es determinar el impacto del panel FAME en las decisiones terapéuticas antimicrobianas en pacientes con sospecha de MEI en las primeras 24 horas de la valoración clínica. Pacientes y métodos. Estudio observacional descriptivo que comenta las manifestaciones cínicas, los resultados de neuroimágenes y paraclínicos, y la antibioticoterapia de pacientes con sospecha de MEI. Se realizó un análisis del impacto que tiene el FAME en la terapia antimicrobiana en las primeras 24 horas de la valoración clínica de los pacientes. Resultados. Se incluyó a 44 pacientes. El tiempo promedio para obtener el resultado del panel FAME en el LCR fue de nueve horas, con un 20,4% (9/44) de pruebas positivas. En las primeras 24 horas de la valoración clínica, su resultado tuvo impacto en las decisiones terapéuticas antimicrobianas en el 75% (33/44) de los casos. En pacientes con alta sospecha clínica de MEI, el resultado del FAME permitió cambiar la terapia empírica inicial a una dirigida en el 15% (3/20) y suspender la terapia empírica inicial en el 35% (7/20) de los sujetos. En pacientes con baja sospecha clínica de MEI, su resultado permitió que al 25% (6/24) se le confirmara la sospecha y se le iniciara antibioticoterapia dirigida; y que al 70,8% (17/24) se le descartara el diagnóstico y no se le iniciara tratamiento. Conclusiones. El resultado del panel FAME en el LCR tiene alto impacto en la toma de decisiones terapéuticas antimicrobianas en las primeras 24 horas de la valoración clínica. Sin embargo, su interpretación debe hacerse con el contexto clínico, la epidemiología local y otros estudios diagnósticos.

Background: COVID-19 may be a new risk factor for stroke. Stroke in COVID-19 varies from 1.1 to 8.1%. Various pathophysiological pathways predispose SARS-CoV-2 infected patients to stroke. Aim: To describe COVID-19 patients with acute stroke in one Colombian Center. Methods: From March 6 2020 and March 6 2021 records of patients with acute stroke and in-hospital positive PCR (Polymerase Chain Reaction) test for Sars-CoV-2 infection were reviewed. Demographic, stroke and COVID-19 characteristics were extracted. Continuous variables were reported in means and ranges. Categorical variables were presented in frequencies and percentage. A descriptive narrative was performed. Results: Of 328 acute stroke patients 14 (4.2%) tested positive for PCR SARS-CoV-2. Mean age 56.4â¯years with 57% males. Five were (35.7%) without vascular risk factors but 9 (64.3%) overweight. Brain infarct diagnosed in 11 (78.5%), 53% with anterior circulation syndromes. Mean NIHSS score 11.8 and 7 (63%) received intravenous thrombolysis. Acute inflammatory blood biomarkers (D-dimer, ferritin, LDH elevated) were positive in all. 11 (78.5%) had symptomatic COVID-19 before stroke with a mean latency of 7â¯days. 12 (85.7%) had severe COVID-19 and 6 (42.8%) required mechanical ventilation. Outcome was unfavorable in 9 (64.3%) (The Modified Rankin Scale (mRS) > 2), mean hospital stay was 21.8â¯days and in-hospital case fatality rate was 14.2%. Conclusion: In susceptible individuals COVID-19 predisposes to stroke. Hypercoagulation and immune thrombosis may be at the culprit for this state. In Colombia, COVID-19 patients with stroke have similar characteristics to the described worldwide.
