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)

Distrofia torácica asfixiante, o síndrome de Jeune, asociada a una malformación espinal cervical / Asphyxiating thoracic dystrophy or Jeune syndrome associated to cervical spine malformation

La distrofia torácica asfixiante, o síndrome de Jeune, es una displasia ósea de herencia autosómica recesiva, con expresión fenotípica variable. El diagnóstico es fundamentalmente clínico y radiológico. Se caracteriza por la presencia de un tórax estrecho y acampanado, polidactilia, costillas horizontalizadas y huesos iliacos cortos, con una alteración típica del techo acetabular en tridente, y suele asociar otras complicaciones: nefrocalcinosis, hepatopatía colestásica, anomalías pancreáticas y retinianas. La distrofia torácica produce hipoplasia pulmonar secundaria e insuficiencia respiratoria restrictiva que puede ser mortal en etapas precoces de la vida. Aunque la existencia de malformaciones espinales no es un hallazgo frecuente, en este caso, el paciente presentaba una malformación de C1 que producía compresión medular. Se realizó una descompresión quirúrgica y, posteriormente, la evolución del paciente ha sido muy favorable. Concluimos que debe realizarse siempre el cribado de malformaciones espinales en pacientes afectados de este síndrome, ya que su tratamiento puede contribuir significativamente a mejorar su pronóstico y calidad de vida(AU)

Asphyxiating thoracic dystrophy-Jeune syndrome is an autosomal recessive disease. It is part of a group of skeletal dysplasias with great clinical variability. Diagnosis is based on clinical and radiographic findings: the syndrome is characterized by a small, narrow chest, variable limb shortness, postaxial polydactyl, horizontally oriented ribs, and short iliac bones with a typical trident appearance of the acetabula. Renal, hepatic, pancreatic and ocular complications may occur later in life. As result of the thoracic dystrophy a lung hypoplasia is produced and a lethal respiratory distress during neonatal and infancy period may occur as well as multiple respiratory infections. Despite spine malformations are not frequently associated, we present a patient who had C1 malformation with cord compression. Surgical cord decompression was done and probably was determinant in his course. We concluded that the screening of spinal malformation in these patients should be always done because it treatment could improve their prognosis and quality of life(AU)
