ABSTRACT
Abstract Introduction: Fungal endocarditis is reported less frequently than bacterial endocarditis, with an incidence of 0-12% of the total pediatric infective endocarditis. Objective: In this study, the incidence of infective endocarditis in Candida bloodstream infections in a tertiary hospital during the periods of 2007 and 2016 was reviewed. Methods: Patients with positive blood or catheter cultures in terms of Candida spp. during the study period of January 2007 and January 2016 were analyzed in terms of Candida infective endocarditis. Infective endocarditis was defined according to the modified Duke criteria. The outcome, possible associated predisposing factors for Candida endocarditis were determined. Results: 221 patients and 256 attacks with positive blood or catheter cultures in terms of Candida were included in the study. The most common Candida species was Candida parapsilosis, isolated in 157 (61.3%) attacks, followed by Candida albicans in 70 (27.3%). Neurological diseases (23%), hemato-oncological diseases (12.1%), previously known heart diseases (8.2%), inborn errors of metabolism (9%) were common comorbidities. Twelve (5.4%) patients had a previous history of cardiac surgery. Among the 221 patients, Candida endocarditis was present in only two (0.9%) of them. Conclusion: Although Candida infective endocarditis is an uncommon but frequently fatal infection in pediatrics, echocardiography should be performed routinely for patients with positive blood or catheter cultures in terms of Candida. Prompt and effective antimicrobial therapy might prevent cardiac surgery in selected cases, however this could not be a general rule for all patients.

Introducción. La linezolida puede causar efectos adversos, como trombocitopenia, que, según lo observado, se relacionan con la administración de linezolida durante más de 2 semanas. Se ha realizado una cantidad limitada de estudios sobre la seguridad y el momento de aparición de los efectos adversos relacionados con la linezolida en los niños. El objetivo de este estudio fue evaluar la incidencia de los efectos adversos asociados con la linezolida, especialmente en relación con el momento de su aparición. Población y métodos. Se incluyeron a todos los niños (< 18 años de edad) que recibieron tratamiento con linezolida durante > 3 días. Se evaluaron los efectos adversos atribuidos a la linezolida y el momento de aparición de los efectos secundarios. Resultados. En total, se incluyeron 179 niños. La mediana de edad de los pacientes fue 4 años (entre 6 días y 17 años). Durante el tratamiento con linezolida, 36 (20,1%) pacientes tuvieron efectos adversos. El efecto adverso más frecuente fue la trombocitopenia, detectada en 26 (14,5%) pacientes. Los demás efectos adversos fueron: elevación de las enzimas hepáticas en 4 pacientes, leucopenia y anemia en 2 pacientes, disfunción renal en 1 y reacciones cutáneas graves en 3 pacientes. Los efectos adversos se detectaron dentro de una mediana de 7,5 días de tratamiento (intervalo: de 4 a 18 días). Entre los 36 pacientes, 26 (72,2%) presentaron un efecto adverso en los primeros 10 días de tratamiento. Conclusiones. Se detectaron efectos adversos transitorios en el 20,1% de los pacientes durante el tratamiento con linezolida. Estos efectos adversos podrían detectarse antes de los 10 días de tratamiento. La linezolida debe recetarse de manera segura a los niños siempre que se vigilen los efectos adversos, en especial el recuento de trombocitos y el nivel de enzimas hepáticas.
Introduction: Linezolid may cause adverse effects such as thrombocytopenia, which were found to be dependent on receiving linezolid for longer than 2 weeks. There are limited studies concerning the safety and timing of linezolid-related adverse effects in children. Objective of this study was to evaluate the incidence of adverse effects associated with linezolid, with especially focusing on the time of occurrence. Population and Methods: All children (<18 years of age) who received >3 days of linezolid therapy were included in this study. Adverse effects attributed to linezolid and time of occurrence of side effects was evaluated. Results: A total of 179 children were enrolled to the study. The patients' median age was 4 years (6 days to 17 years). During linezolid treatment, 36 (20.1%) patients experienced adverse effects. The most common adverse effect was thrombocytopenia that was detected in 26 patients (14.5%). Other adverse effects were as following; elevated liver enzymes in 4 patients, leucopenia and anemia in 2 patients, renal function impairment in one patient, and serious skin reactions in 3 patients. Adverse effects were detected within median 7.5 days of therapy (ranging from 4 to 18 days). Among 36 patients, 26 (72.2%) patients had adverse effect on the first 10 days of therapy. Conclusions: Transient adverse effects were detected in 20.1% of the patients during linezolid therapy. These adverse effects may be detected earlier than ten days of treatment. Linezolid should be prescribed safely in children with monitoring adverse effects especially platelet count and level of liver enzymes.

Background: Vancomycin-resistant enterococci colonization has been reported to increase the risk of developing infections, including bloodstream infections. Aim: In this study, we aimed to share our experience with the vancomycin-resistant enterococci bloodstream infections following gastrointestinal vancomycin-resistant enterococci colonization in pediatric population during a period of 18 months. Method: A retrospective cohort of children admitted to a 400-bed tertiary teaching hospital in Izmir, Turkey whose vancomycin-resistant enterococci colonization was newly detected during routine surveillances for gastrointestinal vancomycin-resistant enterococci colonization during the period of January 2009 and December 2012 were included in this study. All vancomycin-resistant enterococci isolates found within 18 months after initial detection were evaluated for evidence of infection. Findings: Two hundred and sixteen patients with vancomycin-resistant enterococci were included in the study. Vancomycin-resistant enterococci colonization was detected in 136 patients (62.3%) while they were hospitalized at intensive care units; while the remaining majority (33.0%) were hospitalized at hematology-oncology department. Vancomycinresistant enterococci bacteremia was present only in three (1.55%) patients. All these patients were immunosuppressed due to human immunodeficiency virus (one patient) and intensive chemotherapy (two patients). Conclusion: In conclusion, our study found that 1.55% of vancomycin-resistant enterococcicolonized children had developed vancomycin-resistant enterococci bloodstream infection among the pediatric intensive care unit and hematology/oncology patients; according to our findings, we suggest that immunosupression is the key point for developing vancomycinresistant enterococci bloodstream infections. .
