Nirsevimab para la prevención de la enfermedad por virus respiratorio sincitial en niños. Posicionamiento de la Sociedad Española de Infectología Pediátrica / Nirsevimab for the prevention of respiratory syncytial virus disease in children: Statement of the Spanish Society of Paediatric Infectious Disease (SEIP)

Introducción: Recientemente se ha aprobado en Europa y en España el uso de nirsevimab, un anticuerpo monoclonal (AcM) para la prevención de la enfermedad por virus respiratorio sincitial (VRS). Objetivos: Facilitar unas recomendaciones para la administración de nirsevimab para la prevención de la enfermedad por VRS. Métodos: Para la elaboración de estas recomendaciones, se decidió realizar una revisión crítica de la literatura, utilizando la metodología Delphi y la metodología GRADE. Se definió un grupo de expertos. Se realizaron tres rondas para definir las preguntas, manifestarse a favor o en contra, graduar la recomendación, y definir el acuerdo o el desacuerdo con las conclusiones. Resultados: En la población general de recién nacidos, se recomienda administrar rutinariamente nirsevimab para reducir la enfermedad y la hospitalización por bronquiolitis y enfermedad de vías bajas por VRS. Se recomienda administrar nirsevimab a todos los lactantes que nazcan en la estación de alta incidencia de VRS y aquellos que cuando esta comience, tengan menos de seis meses de edad. En los pacientes prematuros de 29 a 35 semanas de edad gestacional, en los lactantes con cardiopatía hemodinámicamente significativa y lactantes con enfermedad pulmonar crónica se recomienda rutinariamente administrar nirsevimab para reducir la enfermedad y la hospitalización por bronquiolitis y enfermedad de vías bajas por VRS. En los pacientes con indicación actual de palivizumab, se recomienda sustituir palivizumab por nirsevimab para reducir la carga de enfermedad de bronquiolitis. Conclusiones: Se recomienda administrar rutinariamente nirsevimab a todos los recién nacidos menores de seis meses nacidos en la estación de VRS o que tengan menos de seis meses cuando entran en la estación invernal, para reducir la carga de enfermedad y la hospitalización por bronquiolitis.

Introduction: Nirsevimab, a monoclonal antibody for the prevention of disease caused by respiratory syncytial virus (RSV), has recently been approved for use in Europe and Spain. Objectives: To provide recommendations for the administration of nirsevimab for prevention of RSV disease. Methods: The approach chosen to develop these recommendations involved a critical review of the literature and the use of the Delphi and GRADE methods. An expert group was formed. The group engaged in three rounds to define the questions, express support or opposition, grade recommendations and establish the agreement or disagreement with the conclusions. Results: In the general neonatal population, routine administration of nirsevimab is recommended to reduce the frequency of illness and hospitalisation for bronchiolitis and RSV lower respiratory tract infection. Nirsevimab is recommended for all infants born in high-incidence RSV season and infants aged less than 6 months at the season onset. In infants born preterm between 29 and 35 weeks of gestation, with haemodynamically significant heart disease or with chronic lung disease, routine administration of nirsevimab is recommended to reduce the incidence of disease and hospitalisation due to bronchiolitis and RSV lower respiratory tract infection. In patients in whom palivizumab is currently indicated, its substitution by nirsevimab is recommended to reduce the burden of bronchiolitis. Conclusions: Routine administration of nirsevimab to all infants aged less than 6 months born during the RSV season or aged less than 6 months at the start of the winter season is recommended to reduce the burden of disease and the frequency of hospitalization due to bronchiolitis.

Mortality in Perinatally HIV-infected Adolescents After Transition to Adult Care in Spain.

INTRODUCTION: After the introduction of combination antiretroviral treatment, (ART) mortality in HIV-infected patients has dramatically decreased. However, it is still high in patients at risk, as adolescents transitioning to adult care (AC) without virologic control. The aim of this study was to characterize mortality and comorbidities of perinatally infected HIV (PHIV) patients after transition to AC. METHODS: A multicenter retrospective study from patients included in the CoRISpe-FARO Spanish cohort was conducted. PHIV patients who died after transition to AC between 2009 and 2019 were included. Clinical, immunovirologic characteristics, treatments received, comorbidities and causes of death were described. RESULTS: Among 401 PHIV patients, 14 died (3.5%). All were Spanish, 11/14 (78.6%) women. The median age at diagnosis was 1.5 years (interquartile range [IQR] 0.5-3.9), at transfer to AC was 18 years [16.1-19.9] and at death was 25.8 years [23.6-27.1]. In pediatric units [pediatric care (PC)], CD4+ nadir was 85 cells/µL [IQR 9.7-248.5] and 6/14 patients were classified as C-clinical stage. During AC, all patients were on C-clinical stage and CD4+ nadir dropped to 11.5 cells/µL [4.5-43.3]. cART adherence was extremely poor: in PC, 8/14 patients registered voluntary treatment interruptions; only one had undetectable VL at transition. In AC, 12/14 patients stopped treatment 2 or more periods of time. All deaths were related to advanced HIV disease. Mental health disorders were observed in 7/14 (50%). Main complications described: recurrent bacterial infections (57.1%), wasting syndrome (42.9%), esophageal candidiasis (28.6%) and Pneumocystis jirovecii pneumonia (28.6%). Four women had 11 pregnancies; 5 children were born (none infected). CONCLUSIONS: Young adults PHIV infected who transition to AC without virologic suppression or proven ability to adhere to ART are at high risk of mortality. Mortality was noted as a consequence of advanced HIV disease, frequent mental health problems and poor adherence to ART.

Response to direct-acting antivirals for hepatitis C treatment in vertically HIV/HCV co-infected patients.

Direct-acting antivirals (DAAs) for HCV treatment have improved tolerance and efficacy among adults, but experience in vertical transmission is scarce. In our vertically HIV/HCV co-infected youth cohort of 58 patients, DAA achieved excellent rates of cure among naïve and pretreated individuals. Treating vertically infected seems important as 29.6% displayed advanced fibrosis at treatment initiation.

Oseltamivir para el tratamiento de la gripe en niños y adolescentes / Oseltamivir for the treatment of influenza in children and adolescents

Introducción: La gripe es una enfermedad generalmente benigna, pero en ocasiones puede ocasionar complicaciones graves. Existe controversia sobre los beneficios del tratamiento con antivirales. Objetivos: Proporcionar unas recomendaciones sobre el tratamiento con oseltamivir en pacientes pediátricos con gripe, basadas en los mejores datos disponibles y válidas en nuestro medio. Métodos: El Grupo de Infecciones Respiratorias de la Sociedad Española de Infectología Pediátrica llevó a cabo una revisión de la bibliografía. Los hallazgos se analizaron mediante la metodología GRADE, y se elaboraron unas recomendaciones. Resultados: No se recomienda el uso sistemático de pruebas diagnósticas para la gripe en el ámbito ambulatorio y en urgencias hospitalarias en pacientes inmunocompetentes con un cuadro clínico compatible. No se recomienda el uso de antivirales a la gran mayoría de los pacientes sanos y asmáticos con gripe o sospecha de gripe estacional, si el objetivo es prevenir eventos graves. No se recomienda el uso de oseltamivir de forma sistemática en pacientes hospitalizados con gripe. Se recomienda tratar con oseltamivir a los pacientes con gripe y neumonía o enfermedad grave o a los pacientes críticos, especialmente durante las primeras 48 h de enfermedad. Se recomienda el tratamiento de los pacientes con factores de riesgo, teniendo en cuenta su enfermedad de base. La vacunación antigripal, junto a las medidas básicas de evitación, continúan siendo la principal herramienta en la prevención de la gripe. Conclusión: En algunas situaciones hay datos suficientes para emitir recomendaciones claras. En otras situaciones los datos son incompletos y solo permiten hacer recomendaciones débiles

Introduction: Influenza is a generally a benign disease, but occasionally it can cause serious complications. There is controversy about the benefits of antiviral treatment. Objectives: To provide some recommendations on the treatment with oseltamivir in paediatric patients with influenza, based on the best data available and valid in our environment. Methods: The Respiratory Infections Group of the Spanish Society of Paediatric Infectious Diseases carried out a review of the literature. The findings were analysed using the GRADE methodology, and recommendations were made. Results: The systematic use of diagnostic tests for influenza in the outpatient setting, or in the emergency room, in immunocompetent patients with a compatible clinical picture is not recommended. If the aim is to prevent serious events, the use of antivirals is not recommended for the vast majority of healthy and asthmatic patients with influenza or suspected seasonal flu. The systematic use of oseltamivir in patients admitted to hospital with influenza is not recommended. Oseltamivir treatment is recommended in any patients with influenza and pneumonia or severe illness, and critically ill patients, especially during the first 48 hours of illness. The treatment of patients with risk factors is recommended, considering their underlying disease. Influenza vaccination, together with basic isolation measures, continue to be the main tool in the prevention of influenza. Conclusion: In some situations, there are sufficient data to issue clear recommendations. In other situations, the data are incomplete, and only allows weak recommendations
