[Increase in the positivity of the galactomannan biomarker during the COVID-19 pandemic in the Fifth Region: Valparaíso]. / Aumento en la positividad del biomarcador galactomanano durante la pandemia de COVID-19 en la Quinta Región: Valparaíso.

BACKGROUND: The current pandemic due to SARS-CoV-2 has caused a high burden on health. Cases and series of invasive aspergillosis associated with COVID-19 patients (CAPA) on mechanical ventilation have been described. AIM: To describe the increase in the positivity of the galactomannan (GM) biomarker during the COVID-19 pandemic in the Fifth Region: Valparaíso. METHOD: Retrospective descriptive study. The GM results in both broncho-alveolar lavage (BAL) and serum and the BAL cultures that were sent to the Mycology Laboratory of the University of Valparaíso from January to September 2020 were reviewed; then they were compared with the examinations of the same period of 2019. RESULTS: There was a significant increase in GMs carried out in LBA during the pandemic, concentrating mainly between the months of July-September. CONCLUSIONS: There was a significant increase in GM carried out in LBA during the pandemic, concentrating mainly between the months of July-September.

[Myroides odoratimimus, a rare cause of soft tissue infection and osteomyelitis. Case report]. / Myroides odoratimimus, una causa infrecuente de infección de tejidos blandos y osteomielitis.

Infections due to Gram-negative bacteria of the genus Myroides are very rare and generally affect the skin and soft tissues of patients with some degree of immunocompromise. We present a case of a 23-year-old patient with a history of myelomeningocele surgically resolved at 3 years of age and bot foot, who presented with a deep infection of the right lower extremity by Myroides odoratimimus. The species identification was carried out with MALDI-TOF and the treatment was initially carried out with meropenem and finally then ciprofloxacin, in addition to right supramaleolar amputation.

Aumento en la positividad del biomarcador galactomanano durante la pandemia de COVID-19 en la Quinta Región: Valparaíso / Increase in the positivity of the galactomannan biomarker during the COVID-19 pandemic in the Fifth Region: Valparaíso

INTRODUCCIÓN: La actual pandemia provocada por SARS-CoV-2 ha provocado una alta carga en la salud pública y privada. Se han descrito casos y series de aspergilosis invasora asociada a pacientes con COVID-19 en ventilación mecánica. OBJETIVO: Describir el aumento en la positividad del biomarcador galactomanano (GM) durante la pandemia de COVID-19 en la Quinta Región: Valparaíso. MATERIALES Y MÉTODO: Estudio descriptivo, retrospectivo. Se revisó la cantidad y los resultados de GM, tanto de lavado bronco-alveolar (LBA) como en suero y los cultivos de LBA enviados al laboratorio de Micología de la Universidad de Valparaíso, desde enero y hasta septiembre del año 2020; luego se compararon con los exámenes recibidos en el mismo período del año 2019. RESULTADOS: Se observó un aumento significativo de los GM realizados en LBA, concentrándose principalmente entre los meses de julio y septiembre. El 29% de las muestras del año 2020 tenía el antecedente de ser de pacientes con COVID-19. Del total de muestras positivas durante el año de la pandemia, 5/12 fueron en pacientes con COVID-19. CONCLUSIONES: Hubo un aumento significativo de los GM realizados en LBA durante la pandemia, concentrándose principalmente entre los meses de julio-septiembre.

Myroides odoratimimus, una causa infrecuente de infección de tejidos blandos y osteomielitis / Myroides odoratimimus, a rare cause of soft tissue infection and osteomyelitis: case report

Resumen Las infecciones por bacterias gramnegativas del género Myroides son muy poco frecuentes y generalmente afectan la piel y tejidos blandos de pacientes con algún grado de inmunocompromiso. Presentamos un caso de una mujer de 23 años, con antecedentes de mielomeningocele operado y pie bot, que cursó con una infección profunda de la extremidad inferior derecha por Myroides odoratimimus. La identificación de especie se realizó con técnica de MALDI-TOF. El tratamiento fue inicialmente con meropenem y ajustado a ciprofloxacina, junto con realizar una amputación supramaleolar derecha.
