The emerging problem of biological treatment in migrant and travelling populations: it is time to extend guidelines for the screening of infectious diseases.

The use of biological agents in the treatment of rheumatic diseases has been widely associated with an increased risk of reactivation of several latent infections. National and international guidelines recommend screening for infectious diseases before starting these drugs. In Western countries screening is limited to latent tuberculosis infection, HIV and viral hepatitis. However, the increasing globalisation and the remarkable number of migrating and travelling people worldwide make this approach no longer adequate. The Italian and Spanish Societies of Rheumatology and Tropical Medicine wish to issue a warning about the need to improve awareness of doctors about the risk of reactivation of infectious tropical diseases in migrant or travelling patients who undergo biological therapy. Thus, the Italian and Spanish Societies are now planning to issue specific recommendations, based on a multidisciplinary contribution and a systematic review of the literature, for screening and follow-up of active and latent chronic infections in candidate patients for biological agents, taking into account the patient's area of origin and risk of infectious diseases.

Hepatotoxicidad por fármacos o productos naturales en ni˜nos / Hepatotoxicity due to drugs or natural products in children

Introducción: La incidencia de las reacciones adversas a medicamentos en pediatría se ha establecido recientemente en 15,1 reacciones por 1.000 niños. Representa un 2% de las admisiones de un hospital pediátrico, similares a las del paciente adulto, y de ellas solo un pequeño porcentaje (menos del 8%) cursan con afectación hepática, que puede ir desde un ligero aumento de las transaminasas hasta una hepatitis fulminante. El objetivo de este estudio ha sido determinar la importancia (frecuencia, formas de presentación, gravedad y cronificación) de la hepatotoxicidad por fármacos o remedios naturales en la población pediátrica. Pacientes y método: Se han incluido a todos los pacientes pediátricos, neonatos y niños en los que se ha sospechado una reacción hepatotóxica, remitidos de 8 hospitales españoles participantes. Para el análisis de la causalidad de cada caso se aplica la escala de Council for International Organizations of Medical. Sciences (CIOMS). Resultados y conclusiones: Se estudian un total de 36 reacciones hepatotóxicas en 33 niños. Los grupos farmacológicos involucrados con mayor frecuencia fueron los antitinfecciosos (71%). Amoxicilina-clavulánico fue el fármaco individual responsable del mayor número de casos (31,4%). Se concluye que el registro de hepatopatías asociadas a medicamentos ha demostrado ser un instrumento útil para la creación de una red activa de especialistas motivados en la detección y comunicación de incidencias de hepatopatía tóxica, aumentando las garantías de certeza diagnóstica(AU)

Introduction: The incidence of adverse drug reactions in children has recently been established at 15.1 reactions per 1000 children. This represents 2% of admissions to a paediatric hospital, and is similar to adult patients. Only a small percentage (less than 8%) may have liver involvement, which can range from a slight increase in transaminases to fulminant hepatitis. The aim of this study was to determine the importance (frequency, types of presentation, severity and chronicity) of hepatotoxicity by drugs or natural remedies in the paediatric population. Patients and method: All paediatric patients, neonates and children who had suspected hepatotoxic reactions notified by the eight participating Spanish hospitals. The Council for International Organizations of Medical Sciences (CIOMS) scale was used for the analysis of causality in each case. Results and conclusions: We studied a total of 36 hepatotoxic reactions in 33 children. The drug classes most frequently involved were antimicrobials (71%). Amoxicillin-clavulanate was the individual drug responsible for the greatest number of cases (31.4%). We conclude that the registration of drugs associated with liver disease has proved a useful tool for creating an active network of motivated specialists in detecting and reporting incidents of toxic liver disease, ensuring increasing diagnostic accuracy(AU)

Viral agents causing lower respiratory tract infections in hospitalized children: evaluation of the Speed-Oligo® RSV assay for the detection of respiratory syncytial virus.

Respiratory syncytial virus (RSV) is the viral agent which is more frequently involved in lower respiratory tract infections (LRTIs) in infants under 1 year of age in developed countries. A new oligochromatographic assay, Speed-Oligo® RSV, was designed and optimized for the specific detection and identification of RSV subtypes A and B. The test was evaluated in 289 clinical samples from 169 hospitalized children using an immunochromatography (IC) test, virus isolation by culture, and an in-house real-time polymerase chain reaction (RT-PCR). Other viruses causing LRTIs were investigated by cell culture or PCR-based tests. Sixty-two patients were infected by RSV (36.7%). In addition, adenovirus, influenza B, parainfluenza 2, and human metapneumovirus were detected in rates ranging from 5 to 8%. A proportion of 10.1% of the patients had mixed infections. The sensitivity, specificity, and positive and negative predictive values were, respectively, 94.9, 99.4, 98.9, and 97.4% for Speed-Oligo® RSV, 92.9, 96.3, 92.9, and 96.3% for RT-PCR/RSV, and 58.4, 98.1, 93.3, and 82.6% for IC. Our rates of viral detection and co-infection were similar to those of previously reported series. Finally, we find that Speed-Oligo® RSV is a rapid and easy-to-perform technique for the detection of RSV and the identification of subtypes A and B.

Multicenter prospective study analysing the role of rotavirus on acute gastroenteritis in Spain.

BACKGROUND: Paediatric rotavirus gastroenteritis is the most frequent cause of acute gastroenteritis (AGE) in children up to 5 years of age worldwide. AIM: To analyse the clinical characteristics of AGE caused by rotavirus comparing to AGE caused by other agents. METHODS: The study was conducted in 30 health-care centers in Spain (25 hospitals and five primary centers) between January and March 2006. Children with AGE up to 2 years of age were included. Stool samples were analysed using immunochromatographic test to identify rotavirus infection. Clinical and epidemiological data were analysed. RESULTS: A total of 1192 children were enrolled (mean age: 11.2 months). Fever, Vomiting, weakness and dehydration were more frequent in rotavirus-positive AGE cases. Severity score was higher and hospitalization was likely in AGE caused by rotavirus. Family AGE illness was more frequent in children with rotavirus-positive AGE. Breastfeeding was found as a protective factor against Rotavirus AGE. CONCLUSION: Rotavirus is the primary causal agent of AGE in children under 2 years of age in Spain, causing more severe symptoms and more hospital admissions than other causal agents. Our data support the interest of the introduction of the available rotavirus vaccines in the Spanish immunization schedule.

[Vaccination schedule of the Spanish association of pediatrics: recommendations 2009]. / Calendario vacunal de la Asociación Española de Pediatría: Recomendaciones 2009.

Based on the available evidence, we, the Vaccine Advisory Committee (CAV) of the Spanish Association of Pediatrics (Asociación Española de Pediatría, AEP), provide information about and comments on vaccine-related innovation during 2008. Modifications to the Vaccine Schedule for 2009 are also discussed. The importance of the recommendation of administration of a varicella booster at start of school (3-4 years of age) is highlighted according to the technical specifications of one of the vaccines. The importance of making the heptavalent pneumococcal conjugate vaccine universally available is reiterated in accordance with the unquestionable results of scientific tests, WHO recommendations, the posture adopted by the majority of neighboring European countries, and the decision taken in 2006 by the autonomous community of Madrid (Spain). New scientific reasons are provided, corroborating the recommendation made by this committee in 2008, for the implementation by Spanish pediatricians of the vaccine against rotavirus and human papilloma virus. With regard to the latter, vaccination should be from 11 to 16 years of age, and then extended, in accordance with the technical specifications of the available vaccine preparations, to 26 years of age. As part of the recommendations, we insist that children in risk groups should be given flu vaccine and hepatitis A vaccine. The committee considers that these two vaccines must also be given, when pediatricians consider it appropriate, to children other than those in risk groups. This recommendation can be regarded as the first step towards a future recommendation of universal vaccination. Finally, this year we include an appendix with recommendations and vaccination strategies to be followed in children who have not previously received vaccines or who have not been completely immunized.

Calendario vacunal de la Asociación Española de Pediatría: Recomendaciones 2009 / Vaccination Schedule of the Spanish Association of Pediatrics: Recommendations 2009

El Comité Asesor de Vacunas (CAV) de la Asociación Española de Pediatría (AEP), con base en la evidencia disponible, informa y comenta las novedades que sobre vacunas se han producido en el año 2008 y aconseja las modificaciones del Calendario Vacunal para el año 2009. Se insiste en recomendar la administración de la segunda dosis de recuerdo de vacuna de varicela al inicio de la escolarización (3-4 años) según las especificaciones de la ficha técnica de una de las vacunas. Se sigue reiterando la importancia de universalizar la vacunación antineumocócica conjugada heptavalente, en consonancia con las incuestionables pruebas científicas existentes, la recomendación de la Organización Mundial de la Salud, la postura adoptada en la mayoría de los países europeos de nuestro entorno y la decisión que tomó en 2006 la Comunidad Autónoma de Madrid en España. Se aportan nuevas razones científicas que corroboran la recomendación, realizada en 2008 por este Comité, de implementar la vacuna frente al rotavirus y el virus papiloma humano; se insiste respecto a esta última en la vacunación prioritaria desde los 11 años hasta los 16 años y se amplía, en consonancia con las fichas técnicas de los preparados vacunales disponibles, hasta los 26 años. En estas recomendaciones vacunales, se insiste en dos vacunas, gripe y hepatitis A, que deben aplicarse a los niños en riesgo. Este Comité considera que las vacunas frente a la gripe y la hepatitis A deben ser implementadas cuando los pediatras lo consideren oportuno, más allá de los grupos de riesgo, como primer paso para una futura recomendación universal. Por último, este año se incluye un anexo sobre las recomendaciones y estrategias vacunales a seguir en el caso de niños no vacunados o inmunizados de forma incompleta (AU)

[Why are pediatric empyemas on the increase in Spain?]. / Por qué hay más empiemas pediátricos en España?

There is a widespread perception among Spanish pediatricians that the incidence of empyema has significantly increased in the last few years, even though the objective information available is limited, and there is no specific active epidemiological surveillance system for this condition. In the present article, we review the situation of empyema in Spain, and discuss the main hypotheses put forward in the international literature to explain this increase, as well as the limitations of the sources available. Despite the scarcity of information, we draw the following conclusions: 1) the incidence of pediatric empyema is increasing in Spain, both generally and when caused by pneumococcus in particular; 2) the reason for this increase remains unknown, and to date no firm link has been established between this phenomenon and the heptavalent conjugate pneumococcal vaccine; and 3) this situation justifies the establishment of prospective systems for the surveillance and control of empyema and, once again, highlights the importance of developing active surveillance systems for pneumococcal disease.

¿Por qué hay más empiemas pediátricos en España? / Why are pediatric empyemas on the increase in Spain?

Existe la percepción entre los pediatras españoles de que el número de casos de empiema pediátrico ha aumentado significativamente en los últimos años; sin embargo, la información objetiva disponible es limitada, y además es una patología de libre declaración para la que no existen sistemas específicos de vigilancia epidemiológica activa. En este trabajo se revisa la situación del empiema pediátrico en España, y se discute las principales hipótesis que se han planteado en la bibliografía internacional para explicar este incremento, así como las limitaciones de las fuentes disponibles. Se concluye que, aunque la información disponible es limitada: a) la incidencia de empiema pediátrico está aumentando en nuestro país, tanto globalmente como la específicamente ocasionada por neumococo; b) la causa de este incremento es desconocida, y hasta la fecha no existen datos que permitan vincularlo a la vacuna antineumocócica conjugada heptavalente, y c) esta situación justifica la puesta en marcha de sistemas prospectivos de vigilancia y control del empiema y, una vez más, pone de relieve la importancia de implantar y desarrollar sistemas de vigilancia activa de la enfermedad neumocócica (AU)

[Criteria for including vaccines in the immunization schedule of the Spanish Association of Pediatrics]. / Criterios de inclusión de vacunas en el calendario de la Asociación Española de Pediatría.

The Vaccine Advisory Committee of the Spanish Association of Pediatrics analyzes and discusses the criteria followed when preparing their yearly Recommended Immunization Schedule for children and adolescents. The relative importance of each criterion in the final recommendation is assessed. Following a review of the current state of affairs of childhood immunization in Spain and of the crucial role played by pediatricians, some reflections are presented on the problems derived from the vaccines recommended by this Committee but not covered by the national health system. Suggestions are made for individual pediatricians who may need to establish specific priorities in the recommendation of these vaccines.

[Immunization schedule of the Spanish Association of Pediatrics: recommendations 2008]. / Calendario vacunal de la Asociación Española de Pediatría: recomendaciones 2008.

The Vaccine Advisory Committee of the Spanish Association of Pediatrics provides information on the new developments in vaccines that have taken place in 2007, based on the available evidence, and discusses these developments. Certain modifications to the Immunization Schedule for 2008 are recommended. A second varicella vaccine booster dose, administered together with the booster dose of the measles-mumps-rubella (MMR) vaccine when children start school (3-4 years), is recommended to avoid vaccine failures against the varicella-zoster virus. Based on current scientific evidence, the importance of universal heptavalent conjugate pneumococcal vaccination, as carried out in most similar European countries and in the autonomous community of Madrid in Spain, is stressed. Human papilloma virus vaccine is included in the Immunization Schedule for girls from 11 years old, and initially, at least up to the age of 16 years. Vaccination against rotavirus in children starting at 6 weeks and completing the series before 6 months is recommended. Other recommendations included in this year's Immunization Schedule are vaccination against influenza and hepatitis A virus in risk groups and at the pediatrician's discretion, as a first step toward the future recommendation of universal immunization.

[Family impact of rotavirus gastroenteritis in children under two years]. / Impacto familiar de la gastroenteritis por rotavirus en menores de dos años.

INTRODUCTION: Acute gastroenteritis (AGE) in infants has a significant impact on the quality of life of their parents. MATERIAL AND METHODS: Cross-sectional study on the sociological family impact related to rotavirus AGE in children under 2 years. The study was carried out in 25 hospitals and 5 primary care centres in Spain. Sociodemographic, epidemiological and clinical data were recorded, as well as the symptomatology of AGE and its severity measured by the Clark scale. Stool samples were tested to determine rotavirus positive (RV+) or negative (RV-). The parents were asked to complete a a family impact questionnaire. RESULTS: Stool specimens were tested in 1087 AGE cases (584 RV+ vs 503 RV-). The 99.5 % of parents whose children were RV+ reported more worries vs. the 97.7 % of RV-, and RV+ had a higher importance score (p < 0.05). A higher percentage of RV+ parents and those with a high importance score reported more time dedicated to dehydration treatment (p < 0.05). The 82.5 % vs. 73.9 % had disruption of their household tasks, with more importance scores (p < 0.05). RV+ had a higher percentage and importance score than RV- ones in all aspects of their child's AGE symptoms, except loss of appetite. CONCLUSION: AGE produces important dysfunctional experiences in daily family life. According to parental perceptions, RV+ produces greater worries and dysfunctions in child behaviour.
