Resumen Introduccion Adecuar la duracion del tratamiento antibiotico es uno de los puntos claves de los programas de optimizacion del uso de antimicrobianos (PROA) dada la relacion entre el riesgo de aparicion de resistencias con los dias de exposicion a antimicrobianos. Metodos Monitorizacion de tratamientos antibioticos por via intravenosa de > 7 dias de duracion en el Hospital Infantil Vall d’Hebron, 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 antibioticos prolongados, prescritos en 81 pacientes. El 78,7% de prescripciones fueron adecuadas. Se realizaron 36 intervenciones sobre las prescripciones inadecuadas, con 52,7% de adaptacion a la recomendacion. Se optimizaron 19 tratamientos (14 suspendidos, 5 desescalados) reduciendo su duracion un 8,75%. Conclusiones La intervencion activa del grupo PROA-NEN permite mejorar la adecuacion antibiotica, reduciendo los tratamientos innecesariamente prolongados, especialmente en ambitos con mayor margen de mejora.

Post-transplant lymphoproliferative disorder (PTLD) are the most common de novo malignancies after liver transplantation (LT) in children. The aim of our study was to assess the role of pre-LT EBV status and post-LT EBV viral load as risk factors for developing PTLD in a cohort of pediatric LT recipients.Data of all children who underwent LT between January 2002 and December 2019 were collected. Two cohorts were built EBV pre-LT primary infected cohort and EBV post-LT primary infected cohort. Moreover, using the maximal EBV viral load, a ROC curve was constructed to find a cutoff point for the diagnosis of PTLD.Among the 251 patients included in the study, fifteen PTLD episodes in 14 LT recipients were detected (2 plasmacytic hyperplasia, 10 polymorphic PTLD, 2 monomorphic PTLD, and 1 Classical-Hodgkin's lymphoma). Patients of the EBV post-LT primary infected cohort were 17.1 times more likely to develop a PTLD than patients of the EBV pre-LT primary infected cohort (2.2-133.5). The EBV viral load value to predict PTLD was set at 211 000 UI/mL (93.3% sensitivity and 77.1% specificity; AUC 93.8%; IC 0.89-0.98). In EBV post-LT primary infected cohort, patients with a viral load above 211 000 were 30 times more likely to develop PTLD than patients with a viral load below this value (OR 29.8; 3.7-241.1; p 0.001).The combination of pretransplant EBV serological status with EBV post-transplant viral load could be a powerful tool to stratify the risk of PTLD in pediatric LT patients.

Introduction: In 2014 the Consensus Document produced by the Spanish Paediatric Societies (SEIP-SERPE-SEOP) was published to help in the diagnosis and treatment of osteoarticular infections (OAI). In 2015 the RIOPed was considered as a multidisciplinary national network for the investigation into OAI. The aim of this study was to assess the level of adaption to the recommendations established in the Consensus during one year of follow-up. Material and methods: A prospective, national multicentre study was carried out in 37 hospitals between September 2015 and September 2016. The study included patients >16 years-old with a diagnosis of OAI, confirmed by microbiological isolation, or probable: septic arthritis (SA) with >40,000 white cells in synovial fluid, or osteomyelitis (OM)/spondylodiscitis (SD) with a compatible imaging test. The results were compared with those obtained in a retrospective study conducted between 2008 and 2012. Results: A total of 235 cases were included, of which 131 were OM, 79 SA, 30 OA, and 15 SD. As regards the complementary tests that the Consensus considered mandatory to perform, radiography was carried out on 87.8% of the cases, a blood culture on 91.6%, and culture of the synovial fluid in 99% of SA. A magnetic resonance (MR) was performed on 71% of the OM cases. The choice of intravenous empirical antibiotic treatment was adapted to the recommendations in 65.1% of cases, and in 62.3% for the oral treatment. Surgery was performed in 36.8% of SA cases (85.7% arthrotomy), with a significant decrease compared to the retrospective study (P = .014). Only 58.5% of cases followed the recommendations on the duration of the treatment; however, a lower duration of intravenous treatment was observed. Conclusions: In general, the level of adaptation to the recommendations that were set by the Expert Group, is good for the complementary tests, and acceptable as regards the choice of antibiotic treatment, although inadequate in almost 40% of cases. A decrease in hospital stay was achieved.

Se realizó RM en el 71% de las OM. La elección del tratamiento antibiótico intravenoso empírico se adecuó a las recomendaciones en el 65,1% de los casos, y en el 62,3% para el tratamiento oral. Se llevó a cabo cirugía en el 36,8% de las AS (85,7% artrotomía), con un descenso significativo respecto al estudio retrospectivo (P = ,014). Solo el 58,5% de casos se ajustaron a las recomendaciones de duración del tratamiento; sin embargo, se comprobó una menor duración del tratamiento intravenoso. Conclusiones: En general, el grado de adecuación a las recomendaciones que marcaron el grupo de expertos es bueno para las pruebas complementarias y aceptable respecto a la elección del tratamiento antibiótico, aun detectándose casi un 40% de inadecuación. Se ha conseguido un descenso de la estancia hospitalaria.

Patients with primary immunodeficiency disease (PID) have an increased risk of experiencing physical activity limitations, social difficulties, and psychological problems due to their chronic condition. Evaluation of their health-related quality of life (HRQOL) and fatigue is crucial in these patients to help understand their complex disease and provide adequate medical care. In this study, we evaluated HRQOL and fatigue in pediatric and young adult patients with PID attending our center. Participants completed the Pediatric Quality of Life Inventory (PedsQL), version 4.0, and the PedsQL multidimensional fatigue module, standard version. Fifty-three PID patients were recruited (age range: 2–23 years). The mean HRQOL score obtained was 66.61 (SD: 18.73) out of 100, and the emotional and work/school dimensions were the ones most highly affected. There were no significant differences in reported quality of life between patients and their caregivers. The mean patient-reported fatigue value was 68.81 (SD: 17.80) out of 100, and the rest-related dimension was the one most highly affected. In the caregivers’ assessment, general fatigue was the most highly affected dimension. The results of this study show that quality of life is poor and fatigue measures are considerably increased in our young adult and pediatric patients with PIDs. These findings can indicate areas requiring more intensive interventions, and they will serve as a basis for comparison of future results.

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.

The SARS-CoV-2 pandemic has caused an increase in antibiotic use in different settings. We describe the antibiotic prescribing prevalence, associated factors and trends, as well as concomitant bacterial infections in children hospitalized with COVID-19 or multisystemic inflammatory syndrome related to SARS-CoV-2 in Spain.
