Mediastinitis secondary to invasive infection by group A Streptococcus in Spain.

This study describes 5 mediastinitis cases secondary to invasive group A Streptococcus (iGAS) disease in a recent outbreak in Spain. Among 398 iGAS cases between January 2019-March 2023, 5 (1.3%) were mediastinitis, 4 occurring in December 2022, all secondary to pneumonia or deep neck infection. We outline the clinical outcome with a review of the scarce pediatric literature.  Conclusion: mediastinistis is a rare but severe complication of iGAS and a high level of suspicion is required to diagnose it. What is Known: • Group A Streptococcus can cause invasive and severe infections in children. • Mediastinitis is a severe complication from some bacterial infections, mainly secondary due to deep-neck abscesses. What is New: • Mediastinitis is an unrecognized complication due to an invasive group A Streptococcus (iGAS) infection. • In cases of a deep-neck abscess or complicated pneumonia a high clinical suspicion of iGAS mediastinitis is required, especially when the clinical course is not favorable.

Antibiotic resistance in bloodstream isolates from high-complexity paediatric units in Madrid, Spain: 2013-2021.

BACKGROUND: Antimicrobial resistance (AMR) has become a significant challenge in high-complexity healthcare settings. AIM: To evaluate the prevalence of AMR in bloodstream isolates from high-complexity paediatric units in Spain over a nine-year period. METHODS: A retrospective observational multicentre study was conducted in three tertiary hospitals, analysing bloodstream isolates from patients aged <18 years admitted to the paediatric intensive care, neonatology, and oncology-haematology units between 2013 and 2021. Demographics, antimicrobial susceptibility, and resistance mechanisms were analysed in two periods (2013-2017 and 2017-2021). FINDINGS: In all, 1255 isolates were included. AMR was more prevalent in older patients and those admitted to the oncology-haematology unit. Multidrug resistance was observed in 9.9% of Gram-negative bacteria (GNB); 20.0% of P. aeruginosa vs 8.6% of Entero-bacterales (P < 0.001), with an increase in Enterobacterales from 6.2% to 11.0% between the first and the second period (P = 0.021). Difficult-to-treat resistance was observed in 2.7% of GNB; 7.4% of P. aeruginosa vs 1.6% of Enterobacterales (P < 0.001), with an increasing trend in Enterobacterales from 0.8% to 2.5% (P = 0.076). Carbapenem resistance among Enterobacterales increased from 3.5% to 7.2% (P = 0.029), with 3.3% producing carbapenemases (67.9% VIM). Meticillin resistance was observed in 11.0% of S. aureus and vancomycin resistance in 1.4% of Enterococcus spp., with both rates remaining stable throughout the study period. CONCLUSION: This study reveals a high prevalence of AMR in high-complexity paediatric units. Enterobacterales showed a concerning increasing trend in resistant strains, with higher rates among older patients and those admitted to oncology-haematology units.

Asociación entre neuroimagen y secuelas neurológicas en pacientes con infección congénita por citomegalovirus / Association between neuroimaging findings and neurological sequelae in patients with congenital cytomegalovirus infection

Introducción: La infección congénita por citomegalovirus (CMV) supone una importante causa de discapacidad. Existen escasas evidencias acerca del valor pronóstico de las lesiones presentes en los estudios de neuroimagen. Objetivo: Analizar la gravedad de las lesiones en la resonancia magnética (RM) y la ecografía transfontanelar, y su relación con déficits neurológicos a largo plazo. Pacientes y métodos: Se realizó un estudio observacional analítico retrospectivo de 36 pacientes con infección congénita por CMV. Se revisaron los estudios de neuroimagen y se clasificaron según la escala de Noyola et al. modificada. Se relacionaron los hallazgos de neuroimagen con la afectación neurológica en su última visita en la consulta de neuropediatría. Resultados: Un total de 36 pacientes fueron estudiados, habiéndose realizado ecografía transfontanelar en 30 y RM cerebral en 29. La ecografía transfontanelar estuvo alterada en 20/30 pacientes, de los cuales, 11 tuvieron alteración en la RM (p = 0,04) y 10 afectación neurológica (p = 0,008). Tuvo una sensibilidad del 83,3%, IC 90%: 58-100 y una especificidad del 44,4%, IC 90%: 18,7-70,2 para la predicción de secuelas neurológicas. La RM estuvo alterada en 20/29 pacientes. Dieciséis de ellos tuvieron afectación neurológica (p < 0,001), teniendo una sensibilidad del 94%, IC 95%: 80-100 y una especificidad del 66,6%, IC 95%: 36-97,5 para la predicción de secuelas neurológicas. Una escala de Noyola et al. ≥ 2 se asoció a retraso psicomotor (p < 0,001). Conclusión: Nuestro trabajo valida los estudios previos en los que se encuentra correlación estadísticamente significativa entre la extensión de las lesiones en neuroimagen y la gravedad de los déficits neurológicos.

Background: Congenital cytomegalovirus (CMV) infection is an important cause of disability. There is little evidence on the prognostic value of lesions identified in neuroimaging studies. Aim: The study aimed to assess the severity of lesions detected with brain MRI and transfontanellar ultrasound and their relationship with long-term neurological deficits. Patients and methods: We performed a retrospective, analytical, observational study of 36 patients with congenital CMV infection. Neuroimaging studies were reviewed and classified according to the modified Noyola’ scale. Imaging findings were compared with neurological alterations in the patients’ most recent follow-up evaluation at the paediatric neurology department. Results: Thirty-six patients were studied (transfontanellar ultrasound: 30; brain MRI: 29). Twenty of 30 patients showed ultrasound abnormalities; of these, 11 showed alterations on brain MR images (P=.04) and 10 had neurological impairment (P=.008). Transfontanellar ultrasound had a sensitivity of 83.3%, 90% CI: 58-100 and a specificity of 44.4%, 90% CI: 18.7-70.2 for predicting neurological sequelae. Brain MRI displayed abnormalities in 20 of 29 patients, of whom 16 had neurological impairment (P<.001). MRI had a sensitivity of 94%, 95% CI: 80-100 and a specificity of 66.6%, 95% CI: 36-97.5 for predicting neurological sequelae. Modified Noyola’ scale values >2 were correlated with psychomotor retardation (P<.001). Conclusions: Our findings validate previous studies reporting a statistical significant correlation between the extension of neuroimaging lesions and severity of neurological deficits. (AU)

Factors associated with severity in invasive community-acquired Staphylococcus aureus infections in children: a prospective European multicentre study.

Staphylococcus aureus is the main pathogen responsible for bone and joint infections worldwide and is also capable of causing pneumonia and other invasive severe diseases. Panton-Valentine leukocidin (PVL) and methicillin-resistant S. aureus (MRSA) have been studied as factors related with severity in these infections. The aims of this study were to describe invasive community-acquired S. aureus (CA-SA) infections and to analyse factors related to severity of disease. Paediatric patients (aged 0-16 years) who had a CA-SA invasive infection were prospectively recruited from 13 centres in 7 European countries. Demographic, clinical and microbiological data were collected. Severe infection was defined as invasive infection leading to death or admission to intensive care due to haemodynamic instability or respiratory failure. A total of 152 children (88 boys) were included. The median age was 7.2 years (interquartile range, 1.3-11.9). Twenty-six (17%) of the 152 patients had a severe infection, including 3 deaths (2%). Prevalence of PVL-positive CA-SA infections was 18.6%, and 7.8% of the isolates were MRSA. The multivariate analysis identified pneumonia (adjusted odds ratio (aOR) 13.39 (95% confidence interval (CI) 4.11-43.56); p 0.008), leukopenia at admission (<3000/mm(3)) (aOR 18.3 (95% CI 1.3-259.9); p 0.03) and PVL-positive infections (aOR 4.69 (95% CI 1.39-15.81); p 0.01) as the only factors independently associated with severe outcome. There were no differences in MRSA prevalence between severe and nonsevere cases (aOR 4.30 (95% CI 0.68- 28.95); p 0.13). Our results show that in European children, PVL is associated with more severe infections, regardless of methicillin resistance.

Neumonía adquirida en la comunidad: tratamiento ambulatorio y prevención / Community acquired pneumonia in children: Outpatient treatment and prevention

La neumonía adquirida en la comunidad (NAC) en la edad pediátrica ha sufrido, en la última década, una serie de cambios epidemiológicos, clínicos, etiológicos y de resistencias a antibióticos, que obligan a replantear su abordaje terapéutico. En este documento, dos de las principales sociedades de especialidades pediátricas involucradas en el diagnóstico y tratamiento de esta entidad, como son la Sociedad Española de Infectología Pediátrica y la Sociedad Española de Neumología Pediátrica, así como el Comité Asesor de Vacunas de la AEP, proponen unas pautas consensuadas de tratamiento y prevención, con el fin de proporcionar a todos los pediatras una guía actualizada. En esta primera parte del consenso, se aborda el tratamiento de los pacientes sin enfermedades de base relevantes con NAC que no precisan ingreso hospitalario, así como la prevención global de esta patología con vacunas. En un siguiente documento se expondrá el abordaje terapéutico tanto de aquellos pacientes en situaciones especiales como de las formas complicadas de la enfermedad

There have been significant changes in community acquired pneumonia (CAP) in children in the last decade. These changes relate to epidemiology and clinical presentation. Resistance to antibiotics is also a changing issue. These all have to be considered when treating CAP. In this document, two of the main Spanish pediatric societies involved in the treatment of CAP in children, propose a consensus concerning therapeutic approach. These societies are the Spanish Society of Paediatric Infectious Diseases and the Spanish Society of Paediatric Chest Diseases. The Advisory Committee on Vaccines of the Spanish Association of Paediatrics (CAV-AEP) has also been involved in the prevention of CAP. An attempt is made to provide up-to-date guidelines to all paediatricians. The first part of the statement presents the approach to ambulatory, previously healthy children. We also review the prevention with currently available vaccines. In a next second part, special situations and complicated forms will be addressed

Consensus statement by the Spanish Society of Paediatric Infectious Diseases (SEIP) and the Spanish Society of Paediatric Chest Diseases (SENP)

Desde hace más de una década, los casos complicados de neumonía adquirida en la comunidad, fundamentalmente con empiema pleural o formas necrosantes, comenzaron a ser más frecuentes en niños, según la amplia documentación procedente de numerosos países. El abordaje terapéutico óptimo de estos casos, tanto desde el punto de vista médico (antibióticos, fibrinolíticos) como técnico-quirúrgico, (drenaje pleural, videotoracoscopia) continúa siendo controvertido. En este documento, la Sociedad Española de Infectología Pediátrica y la Sociedad Española de Neumología Pediátrica revisan la evidencia científica y proponen unas pautas consensuadas de tratamiento de estos casos, fundamentalmente para el abordaje del derrame pleural paraneumónico en niños, así como la actuación en situaciones especiales, sobre todo en la cada vez más frecuente población pediátrica con enfermedades de base o inmumodepresión

The incidence of community-acquired pneumonia complications has increased during the last decade. According to the records from several countries, empyema and necrotizing pneumonia became more frequent during the last few years. The optimal therapeutic approach for such conditions is still controversial. Both pharmacological management (antimicrobials and fibrinolysis), and surgical management (pleural drainage and video-assisted thoracoscopic surgery), are the subject of continuous assessment. In this paper, the Spanish Society of Paediatric Infectious Diseases and the Spanish Society of Paediatric Chest Diseases have reviewed the available evidence. Consensus treatment guidelines are proposed for complications of community-acquired pneumonia in children, focusing on parapneumonic pleural effusion. Recommendations are also provided for the increasing population of patients with underlying diseases and immunosuppression

Aislamiento de Clostridium difficile en niños hospitalizados con diarrea / Clostridium difficile isolation in children hospitalized with diarrhea

Introducción: Clostridium difficile es la principal causa de diarrea nosocomial en adultos, y su incidencia está aumentado en los últimos años. Es difícil determinar su impacto en niños debido a las altas tasas de colonización. Material y métodos: Estudio retrospectivo en menores de 15 años ingresados con diarrea a lo largo de un año. Se estudiaron las características epidemiológicas, clínicas, analíticas y la evolución de los niños con infección por Clostridium difficile (ICD) en comparación con otros aislamientos. Los factores predictores de ICD fueron determinados mediante análisis multivariante. Resultados: Se identificaron 250 niños con diarrea, realizándose estudio microbiológico completo en 174. En 79 (45,4%) se llegó al diagnóstico: 25,6% ICD (n=19; 13 enterotoxigénicos); 28,6% otras bacterias (n=21) y 45,8% virus (n=34; rotavirus n=31; adenovirus n=3). Un 68,4% fueron menores de 2 años, y un 15,8% fueron adquiridos en la comunidad. En comparación con otras causas de diarrea, la ICD se asoció a comorbilidad (p<0,0001), contacto reciente con el sistema sanitario (p<0,0001), estancia en UCI (p=0,003) y exposición reciente a antibióticos (p<0,0001). Los pacientes con ICD cursaron de forma oligosintomática. No hubo diferencias clínicas entre las ICD productoras o no de toxina, siendo la comorbilidad el principal asociado con la ICD (OR 40,02; IC 95% 6,84-232,32; p<0,0001). Conclusiones: El aislamiento de Clostridium difficile es frecuente en niños hospitalizados con diarrea en nuestro medio. La ICD resultó más frecuente en niños pequeños con comorbilidad y contacto reciente con el sistema sanitario, presentado, en su mayoría, un curso clínico oligosintomático. Se necesitan más estudios para conocer la epidemiología de esta infección en niños (AU)

Introduction: Clostridium difficile is the leading cause of nosocomial and antibiotic-associated diarrhea in adults, and its incidence has substantially risen over the last few years. The prevalence of this infection in children is difficult to assess due to the high rates of colonization in this setting. Material and methods: A one-year retrospective study was conducted on children under 15 years admitted to hospital with acute diarrhea. Epidemiological, clinical, laboratory findings and outcome of children with Clostridium difficile infection (CDI) were compared to other causes of diarrhea. Risk factors for CDI were identified by multivariate analysis. Results: Two hundred and fifty children with acute diarrhea were identified. A microbiological pathogen was identified in 79 (45.4%) of 174 patients who underwent complete testing: 19 CDI (25.6%, 13 of which were enterotoxin-producing), 21 other bacteria (28.6%), and 34 viruses (45.8%; rotavirus n=31; adenovirus n=3). The estimated incidence of CDI was 3 cases/1,000 admissions, with 68.4% of them occurring in children younger than 2 years. Overall, 15.8% were community-acquired. Compared to other causes of diarrhea, CDI was associated with comorbidity (P<.0001), recent contact with the health-care system (P<.0001) or intensive care unit stay (P=.003) and exposure to antibiotics in the previous month (P<.0001). The clinical course of children with CDI was less symptomatic. There were no clinical differences between Clostridium difficile toxin-producers and non-toxin producers. Comorbidity was identified as the main risk factor associated with CDI (OR 40.02, 95% CI 6.84-232.32; P<.0001). Conclusions: The isolation of Clostridium difficile is common in hospitalized children with diarrhea in our setting. CDI is more frequent in children with comorbidity and recent contact with the health-care system, presenting a mostly oligosymptomatic clinical course. Further studies are needed to understand the epidemiology of this infection in pediatrics, especially the percentage of asymptomatic carriers (AU)

In this document, two of the main Spanish pediatric societies involved in the treatment of CAP in children, propose a consensus concerning therapeutic approach. These societies are the Spanish Society of Paediatric Infectious Diseases and the Spanish Society of Paediatric Chest Diseases. The Advisory Committee on Vaccines of the Spanish Association of Paediatrics (CAV-AEP) has also been involved in the prevention of CAP. An attempt is made to provide up-to-date guidelines to all paediatricians. The first part of the statement presents the approach to ambulatory, previously healthy children. We also review the prevention with currently available vaccines. In a next second part, special situations and complicated forms will be addressed.
