ABSTRACT
Introduction: Actions to reduce and optimize antimicrobial use are crucial in the management of infectious diseases to counteract the emergence of short- and long-term resistance. This is particularly important for pediatric patients due to the increasing incidence of serious infections caused by resistant bacteria in this population. The aim of this study was to evaluate the impact of a pediatric antimicrobial stewardship program (PROA-NEN) implemented in a Spanish tertiary hospital by assessing the use of systemic antimicrobials, clinical indicators, antimicrobial resistance, and costs. Methods: In this quasi-experimental, single-center study, we included pediatric patients (0-18 years) admitted to specialized pediatric medical and surgical units, as well as pediatric and neonatal intensive care units, from January 2015 to December 2019. The impact of the PROA-NEN program was assessed using process (consumption trends and prescription quality) and outcome indicators (clinical and microbiological). Antibiotic prescription quality was determined using quarterly point prevalence cross-sectional analyses. Results: Total antimicrobial consumption decreased during the initial three years of the PROA-NEN program, followed by a slight rebound in 2019. This decrease was particularly evident in intensive care and surgical units. Antibiotic use, according to the WHO Access, Watch and Reserve (AWaRe) classification, remained stable during the study period. The overall rate of appropriate prescription was 83.2%, with a significant increase over the study period. Clinical indicators did not substantially change over the study period. Direct antimicrobial expenses decreased by 27.3% from 2015 to 2019. Conclusions: The PROA-NEN program was associated with reduced antimicrobial consumption, improved appropriate use, and decreased costs without compromising clinical and/or microbiological outcomes in patients.
ABSTRACT
BACKGROUND: Data on antifungal prescribing in neonatal patients are limited to either single-center or single-country studies or to 1-day recording. Therefore, we assessed antifungal longitudinal usage in neonatal units (NUs) within Europe. METHODS: CALYPSO, a prospective weekly point prevalence study on antifungal drug usage in NUs in 18 hospitals (8 European countries), was conducted in 2020 during a 12-week period. All patients receiving systemic antifungals were included. Ward demographics were collected at the beginning; ward and patient data including indication, risk factors and antifungal regimen were weekly collected prospectively. RESULTS: Among 27 participating NUs, 15 (56%) practiced antifungal prophylaxis for neonates with birth weight <1000 g or <1500 g and additional risk factors. In total, 174 patients received antifungals with a median frequency per week of 10.5% ranging from 6.9% to 12.6%. Indication for antifungal prescribing was prophylaxis in 135/174 (78%) courses and treatment in 22% [39 courses (69% empirical, 10% preemptive, 21% targeted)]. Fluconazole was the most frequent systemic agent used both for prophylaxis (133/135) and treatment (15/39, 39%). Among neonates receiving prophylaxis, the most common risk factors were prematurity (119/135, 88%), mechanical ventilation (109/135, 81%) and central vascular catheters (89/135, 66%). However, gestational age <28 weeks was only recorded in 55/135 (41%) courses and birth weight <1000 g in 48/135 (35%). Most common reason for empirical treatment was late-onset sepsis; all 8 targeted courses were prescribed for invasive candidiasis. CONCLUSION: Antifungal usage in European NUs is driven by prophylaxis and empirical treatment with fluconazole being the most prescribed agent for both indications.
ABSTRACT
La neutropenia febril es una de las principales complicaciones infecciosas que sufren los pacientes pediátricos oncohematológicos, y a pesar los avances en diagnóstico y tratamiento, siguen condicionando una mortalidad y morbilidad significativa. Estos pacientes agrupan una serie de factores de riesgo de infección, donde destaca la neutropenia asociada a quimioterapia, la disrupción de barreras cutáneo-mucosas y el uso de dispositivos intravasculares. El abordaje diagnóstico y terapéutico precoz de los episodios de neutropenia febril en los pacientes oncohematológicos, ajustado a las características individuales de cada paciente, es fundamental para mejorar su pronóstico. Por ello, diseñar protocolos de abordaje, que sistematicen su atención, permite optimizar y homogeneizar su abordaje. Además, racionalizar el uso de los antimicrobianos, ajustando la duración y el espectro de los mismos, es crucial para hacer frente al incremento de resistencias a antimicrobianos. El objetivo de este documento, elaborado entre la Sociedad Española de Infectología Pediátrica y la Sociedad Española de Hematología y Oncología Pediátrica, es dar recomendaciones de consenso sobre el manejo de la neutropenia febril en el paciente oncohematológico, respecto al abordaje inicial, terapia secuencial y de soporte e infección fúngica invasiva, que cada centro debe adaptar a las características de sus pacientes y epidemiología local.

Febrile neutropenia is one of the main infectious complications experienced by paediatric patients with blood or solid tumours, which, despite the advances in diagnosis and treatment, are still associated with a significant morbidity and mortality. These patients have several risk factors for infection, chief of which are chemotherapy-induced neutropenia, the disruption of cutaneous and mucosal barriers and the use of intravascular devices. Early diagnosis and treatment of febrile neutropenia episodes based on the patient's characteristics is essential in patients with blood and solid tumours to improve their outcomes. Therefore, it is important to develop protocols in order to optimise and standardise its management. In addition, the rational use of antibiotics, with careful adjustment of the duration of treatment and antimicrobial spectrum, is crucial to address the increase in antimicrobial drug resistance. The aim of this document, developed jointly by the Spanish Society of Pediatric Infectious Diseases and the Spanish Society of Pediatric Hematology and Oncology, is to provide consensus recommendations for the management of febrile neutropenia in paediatric oncology and haematology patients, including the initial evaluation, the stepwise approach to its treatment, supportive care and invasive fungal infection, which each facility then needs to adapt to the characteristics of its patients and local epidemiological trends.

Introducción: Adecuar la duración del tratamiento antibiótico es uno de los puntos claves de los programas de optimización del uso de antimicrobianos (PROA) dada la relación entre el riesgo de aparición de resistencias con los días de exposición a antimicrobianos. Métodos: Monitorización de tratamientos antibióticos por vía intravenosa de > 7 días de duración en el Hospital Infantil Vall dHebron, Barcelona, mediante cortes transversales semanales durante 24 semanas, con recomendaciones posteriores a los prescriptores para adecuar su uso. Resultados: Se realizaron 190 revisiones de 146 tratamientos antibióticos prolongados, prescritos en 81 pacientes. El 78,7% de prescripciones fueron adecuadas. Se realizaron 36 intervenciones sobre las prescripciones inadecuadas, con 52,7% de adaptación a la recomendación. Se optimizaron 19 tratamientos (14 suspendidos, 5 desescalados) reduciendo su duración un 8,75%. Conclusiones: La intervención activa del grupo PROA-NEN permite mejorar la adecuación antibiótica, reduciendo los tratamientos innecesariamente prolongados, especialmente en ámbitos con mayor margen de mejora.(AU)
Introduction: the duration adequacy of antibiotic regimens is one of the key points of Antimicrobial Stewardship Programs (ASP) given the relationship between the risk of resistance and days of exposure to antimicrobials. Methods: monitoring activities of intravenous antibiotics longer than 7 days at Hospital Infantil Vall dHebron, Barcelona, by reviewing data over a 34-weeks period from weekly cross-sectional analysis, followed by recommendations to prescribers to adapt their use. Results: a total of 81 patients with 146 prolonged intravenous antibiotic treatments (78.8% of prescriptions were adequate) were reviewed. A total of 190 revisions were performed. 36 interventions on inappropriate prescriptions were carried out (52.7% of adherence to recommendation). Nineteen treatments were optimized (14 suspended, 5 de-escalated) reducing their duration by 8.75%. Conclusions: active intervention of ASP group is an effective tool to improve antibiotic optimization, reducing unnecessarily prolonged treatments, mainly on these areas with a greater range of improvement.(AU)

INTRODUCTION: Pneumocystis jirovecii pneumonia (PJP) is a life-threatening condition in immunocompromised children. Our aim is to analyze the epidemiologic and clinical characteristics of PJP cases in our setting, describing the prognosis and related risk factors. METHODS: Retrospective study including all pediatric patients (≤ 18 years) with PJP admitted to our hospital (January 1989-December 2016). Case definition: patient with acute pneumonitis and P.jirovecii detection in bronchoalveolar lavage or tracheal aspirate using methenamine silver or direct antibody fluorescence staining, or Real-Time Polymerase Chain Reaction. RESULTS: Twenty-five cases (0.9 cases/year) were identified. Median age was 2.2 years (interquartile range: 0.5-12.3), 64% were male, and 12% were receiving appropriate antimicrobial prophylaxis. Cytomegalovirus coinfection was detected in 26% cases. The most common underlying diseases were primary immunodeficiencies (36%) and 16% were human immunodeficiency virus (HIV)-infected children. Eighteen were admitted to the pediatric intensive care unit (PICU) and overall 30-day mortality was 20% (31.25% in HIV non-infected vs 0% in HIV-infected patients; OR: 0.33, 95% CI: 0.02-7.24, p = 0.55). Clinical outcome was worse in girls and those patients requiring adjuvant steroid therapy. HIV non-infected patients, higher initial LDH, younger age and shorter time elapsed between diagnosis of PJP and the underlying disease were identified as risk factors to be admitted to the PICU (p = 0.05, p = 0.026, p = 0.04 and p = 0.001 respectively). CONCLUSION: Accompanying the widespread use of combined antiretroviral therapy, PJP has been diagnosed almost exclusively in HIV non-infected children at our institution. Moreover, significant higher morbidity rates associated with PJP are seen in this group of patients
INTRODUCCIÓN: La neumonía por Pneumocystis jirovecii (PJP) es una enfermedad potencialmente letal en niños inmunocomprometidos. Nuestro objetivo es analizar las características epidemiológicas y clínicas de la PJP, describiendo el pronóstico y los factores de riesgo. MÉTODOS: Estudio retrospectivo (enero 1989-diciembre 2016) de pacientes pediátricos (≤ 18 años) con PJP. Definición de caso: paciente con neumonitis aguda y detección de P. jirovecii en lavado broncolaveolar o aspirado traqueal usando tinción con plata-metenamina o inmunofluorescencia directa, o reacción en cadena de polimerasa en tiempo real. RESULTADOS: Se identificaron veinticinco casos (0,9 casos/año); edad mediana: 2,2 años (rango intercuartílico: 0,5-12,3), 64% de sexo masculino, y 12% bajo profilaxis anti-PJP. La coinfección por citomegalovirus se demostró en el 26%. Las enfermedades subyacentes más frecuentes fueron las inmunodeficiencias primarias (36%) y el 16% estaban infectados por el VIH. Dieciocho ingresaron en Cuidados Intensivos Pediátricos (UCIP) y la mortalidad global a los 30 días fue del 20% (31,25% en VIH- vs 0% VIH + ; OR: 0,33 95%CI 0,02-7,24 p = 0,55). El pronóstico fue peor en niñas y en aquellos que recibieron tratamiento adyuvante con corticoides. Se identificaron como factores de riesgo para ingreso en UCIP la ausencia de infección por VIH, valores iniciales elevados de LDH, menor edad y un período más corto entre el diagnóstico de PJP y la enfermedad subyacente (p = 0,05, p = 0,026, p = 0,04 y p = 0,001, respectivamente). CONCLUSIONES: Tras la aplicación generalizada de la terapia antirretroviral, la PJP se diagnostica casi exclusivamente en niños no infectados por el VIH en los que, además, se identificó una mayor morbilidad

Background: Infections related to non-surgical manipulation of the biliary tract (NSMBT) are common events despite periprocedural antibiotic prophylaxis (PAP). Since June 2017, our local protocol has indicated a 24-h regimen of intravenous piperacillintazobactam for this purpose. Objective: We aimed to describe the incidence and characteristics of NSMBT-related paediatric infections, define risk factors for their development, and analyse adherence to our PAP protocol. Materials and methods: Epidemiological, clinical, and microbiological data were collected in consecutive NSMBT procedures performed in paediatric patients (<18 years) in our centre (20102019). Results: 113 procedures in 37 patients, median age 4 years (IQR 18), were included. Main underlying diseases were biliary atresia (32%) and cancer (14%). Sixty-eight percent had undergone liver transplant and 70% hepaticojejunostomy. In 44 procedures (39%), the intervention was performed during the course of infection and previously prescribed antibiotic treatment was maintained. In the other 69, PAP was specifically indicated for NSMBT; antibiotic adequacy increased from 35% to 100% after June 2017. In total, 32 NSMBT-related infections (28%) occurred, mainly in the first 24h post-procedure (72%); no deaths happened. Causative pathogens were Gram-negative rods (64%), Gram-positive cocci (28%), and Candida spp. (8%). Main related risk factors were hepaticojejunostomy, biliary obstruction, and liver transplant. Conclusions: NSMBT in children entails a significant infection risk, even under antibiotic prophylaxis, being hepaticojejunostomy the main risk factor. Infectious complications mainly occurred immediately after the procedure. After establishing a PAP protocol, 100% of interventions received appropriate prophylaxis, decreasing antibiotic exposure time and potentially, the length of hospital stay.(AU)
Antecedentes: Las infecciones relacionadas con la manipulación no quirúrgica de las vías biliares (MNQVB) son acontecimientos frecuentes, a pesar de la profilaxis antibiótica periprocedimiento (PAP). Desde junio de 2017, nuestro protocolo local indica una pauta de 24 h de piperacilina/tazobactam por vía intravenosa para este fin. Objetivo: El objetivo era describir la incidencia y las características de las infecciones pediátricas relacionadas con la MNQVB, definir los factores de riesgo para su desarrollo y analizar el cumplimiento de nuestro protocolo de PAP. Materiales y métodos: Se recogieron datos epidemiológicos, clínicos y microbiológicos en procedimientos consecutivos de MNQVB realizados en pacientes pediátricos (< 18 años) en nuestro centro (2010-2019). Resultados: Se incluyeron 113 procedimientos en 37 pacientes, con una mediana de edad de 4 años (RIC 1-8). Las principales enfermedades subyacentes fueron atresia biliar (32%) y cáncer (14%). El 68% se había sometido a un trasplante de hígado y el 70% a una hepaticoyeyunostomía. En 44 procedimientos (39%), la intervención se realizó durante el transcurso de la infección y se mantuvo el tratamiento antibiótico recetado previamente. En los otros 69, la PAP estaba indicada específicamente para la MNQVB; la eficacia de los antibióticos aumentó del 35 al 100% después de junio de 2017. En total, se produjeron 32 infecciones relacionadas con la MNQVB (28%), principalmente en las primeras 24 h posteriores al procedimiento (72%); no se produjo ninguna muerte. Los patógenos causantes fueron bacilos gramnegativos (64%), cocos grampositivos (28%) y Candida spp. (8%). Los principales factores de riesgo relacionados fueron la hepaticoyeyunostomía, la obstrucción biliar y el trasplante de hígado.(AU)

OBJETIVO: Analizar el estado vacunal de los niños diagnosticados de tos ferina y comparar las manifestaciones clínicas de los bien vacunados y de los no vacunados o con vacunación incompleta. Métodos Se ha revisado la historia clínica y el carnet vacunal de los pacientes menores de 16 años visitados en el servicio de urgencias del Hospital Universitario Vall d'Hebron de Barcelona con tos ferina confirmada por estudio microbiológico. El periodo de estudio comprende del 1 de enero de 2009 al 31 de diciembre de 2011.ResultadosSe han investigado 212 casos: 35 en 2009, 28 en 2010 y 149 en 2011. La reacción en cadena de la polimerasa en tiempo real (RT-PCR) fue positiva en 210 pacientes, y el cultivo, en 73. Los lactantes menores de 6 meses representan el 36,8% de los casos. No estaban vacunados 44 (21,5%) pacientes. Cuarenta y cuatro (21,5%) tenían entre 2 y 5 meses de vida y habían recibido una o 2 dosis de vacuna. Habían completado la primovacunación y las dosis de recuerdo (3 a 5 dosis, según la edad) 117 niños (57%); el 76,9% (90 casos) había recibido la última dosis de vacuna hacía menos de 4 años. Al comparar las manifestaciones clínicas de los pacientes con vacunación completa y con vacunación incompleta o no vacunados, solo la cianosis se ha presentado con más frecuencia en el segundo grupo (p < 0,001). La probabilidad de hospitalización ajustada por la edad se asoció de forma significativa con la ausencia de vacunación (p = 0,001). La letalidad en los pacientes hospitalizados fue del 1,3%.ConclusionesEl número de casos de tos ferina atendidos en nuestro centro ha aumentado de forma importante en el último año. El 57% de los pacientes estaban bien vacunados y el 76,9% habían recibido la última dosis en los últimos 4 años. Se necesitan otras estrategias de vacunación (adolescentes, adultos y embarazadas, y estrategia del nido) para proteger a los lactantes menores de 6 meses de edad, así como vacunas más efectivas
OBJECTIVE: To analyse the vaccination status of children diagnosed with pertussis and to compare the clinical manifestations of fully vaccinated with unvaccinated, or incompletely-vaccinated, children. METHODS: The clinical histories and vaccination cards of patients under 16 years of age seen in the Emergency Room of the University Hospital Vall d'Hebron, Barcelona (Spain), for pertussis confirmed by a microbiological study were reviewed. The study period lasted from January 1, 2009 to December 31, 2011. RESULTS: Two hundred and twelve cases were studied: 35 in 2009, 28 in 2010 and 149 in 2011. RT-PCR was positive in 210 patients, and 73 had a positive culture. Infants under 6 months of age account for 36.8% of all cases. Forty-four patients (21.5%) were not vaccinated. Forty-four (21.5%) children were between 2 and 5 months of age and had received 1-2 vaccine doses. One hundred and seventeen (57%) children were fully vaccinated; 76.9% (90 cases) had received the last dose less than 4years ago. When clinical manifestations of the fully vaccinated patients were compared with those of the non-vaccinated or incompletely-vaccinated children, only cyanosis was found with a higher frequency in the latter group (P < .001). The age-adjusted probability of hospitalisation was significantly associated with non-vaccination (P = .001). The case mortality rate among inpatients was 1.3%. CONCLUSIONS: The number of pertussis cases seen in our centre has risen significantly in the last year. More than half (57%) of the patients were fully vaccinated, and 76.9% had received the last dose in the previous 4 years. Other vaccination strategies, such as vaccination of adolescents, adults, and pregnant women, as well as a cocoon strategy are required to protect infants under 6 months of age. More effective vaccines need to be developed
