Salmonella subespecie enterica es la más frecuente a nivel mundial, siendo el serovar Enteritidis el más importante. Tiene una alta tasa de complicaciones, predominando las colecciones y abscesos, por lo que se recomienda realizar una neuroimagen a todos los pacientes. A pesar que el manejo no está estandarizado, hay consenso en que el tratamiento de elección son las cefalosporinas de tercera generación. La resistencia antimicrobiana es infrecuente pero va en aumento, principalmente en países subdesarrollados. Presentamos el primer caso publicado en Chile de una meningitis por S. Enteritidis en un lactante de 11 meses, que se presentó con fiebre y una convulsión focalizada, con hemocultivos y cultivo de líquido cefalorraquídeo positivos. El paciente completó tratamiento con ceftriaxona y ciprofloxacina por cuatro semanas con buena respuesta.

Summary Background Obesity increases the severity of coronavirus disease 2019 illness in adults. The role of obesity in short‐term complications and post‐acute sequelae in children is not well defined. Objective To evaluate the relationship between obesity and short‐term complications and post‐acute sequelae of SARS‐CoV‐2 infection in hospitalized paediatric patients. Methods An observational study was conducted in three tertiary hospitals, including paediatric hospitalized patients with a confirmatory SARS‐CoV‐2 RT‐PCR from March 2020 to December 2021. Obesity was defined according to WHO 2006 (0–2 years) and CDC 2000 (2–20 years) growth references. Short‐term outcomes were intensive care unit admission, ventilatory support, superinfections, acute kidney injury, and mortality. Neurological, respiratory, and cardiological symptoms and/or delayed or long‐term complications beyond 4 weeks from the onset of symptoms were considered as post‐acute sequalae. Adjusted linear, logistic regression and generalized estimating equations models were performed. Results A total of 216 individuals were included, and 67 (31.02%) of them had obesity. Obesity was associated with intensive care unit admission (aOR = 5.63, CI95% 2.90–10.94), oxygen requirement (aOR = 2.77, CI95% 1.36–5.63), non‐invasive ventilatory support (aOR = 6.81, CI95% 2.11–22.04), overall superinfections (aOR = 3.02 CI95% 1.45–6.31), and suspected bacterial pneumonia (aOR = 3.00 CI95% 1.44–6.23). For post‐acute sequalae, obesity was associated with dyspnea (aOR = 9.91 CI95% 1.92–51.10) and muscle weakness (aOR = 20.04 CI95% 2.50–160.65). Conclusions In paediatric hospitalized patients with COVID‐19, severe short‐term outcomes and post‐acute sequelae are associated with obesity. Recognizing obesity as a key comorbidity is essential to develop targeted strategies for prevention of COVID‐19 complications in children.
