Consensus document on the primary prevention of cow's milk protein allergy in infants aged less than 7 days.

INTRODUCTION: Cow's milk protein allergy (CMPA) is the most frequent food allergy in the first year of life. There is no clear consensus regarding its prevention. A recommendation to avoid CMP in the first week of life as a preventive measure in all infants, regardless of their atopic risk, has recently been published. The purpose of this document is to issue a recommendation on the use of extensively hydrolyzed CMP formulas in the first week of life for the primary prevention of CMPA. METHODS: A group of experts was formed with members proposed by the Spanish Association of Pediatrics (AEP), the Spanish Society of Clinical Immunology and Allergology and Pediatric Asthma (SEICAAP), the Spanish Society of Pediatric Gastroenterology, Hepatology and Nutrition (SEGHNP) and the Spanish Society of Neonatology (SENEO). The group conducted a critical review of the evidence on the subject published in the last 10 years. RESULTS: The search yielded 72 studies, of which 66 were rejected for not meeting the inclusion criteria. The final review included 6 documents: 3 clinical trials and 3 systematic reviews, 2 of them with meta-analysis. There was no evidence of a statistically significant reduction in the incidence of CMPA in the infants who received hypoallergenic formulae or exclusive breastfeeding. CONCLUSION: Based on the current evidence, it is not possible to draw clear conclusions about the effect of avoiding CMP in the first week of life for prevention of CMPA. Although there are data that suggest a certain beneficial effect of avoiding CMPA in atopic risk infants, these results are not conclusive enough to extend the recommendation to the general population.

Documento de consenso en la prevención primaria de alergia a proteínas de leche de vaca en lactantes menores de 7 días de vida / Consensus document on the primary prevention of cow's milk protein allergy in infants aged less than 7days

Introducción: La alergia a las proteínas de la leche de vaca (APLV) es la alergia alimentaria más frecuente en el primer año de vida. No existe un consenso claro respecto a su prevención. Recientemente se ha publicado la recomendación de evitar estas proteínas en la primera semana de vida como medida de prevención en todos los niños, con independencia de su riesgo atópico. El objetivo de este documento es emitir una recomendación sobre el uso de fórmulas extensamente hidrolizadas de PLV en la primera semana de vida para la prevención primaria de la APLV. Métodos: Se constituyó un grupo de expertos propuestos por la Asociación Española de Pediatría (AEP), la Sociedad Española de Inmunología Clínica y Alergología y Asma Pediátrica (SEICAAP), la Sociedad Española de Gastroenterología, Hepatología y Nutrición Pediátrica (SEGHNP) y la Sociedad Española de Neonatología (SENEO). Se realizó una revisión crítica de la evidencia publicada en los últimos 10 años sobre el tema. Resultados: Se seleccionaron 72 estudios, de los cuales 66 fueron rechazados por no cumplir los criterios de inclusión. Se incluyeron en la revisión 6 documentos: 3 ensayos clínicos y 3 revisiones sistemáticas, 2de ellas con metaanálisis. No se observó una reducción estadísticamente significativa en la incidencia de APLV en los grupos de lactantes que recibieron fórmulas hipoalergénicas ni lactancia materna exclusiva. Conclusión: Con base en las evidencias existentes en la actualidad, no se pueden establecer conclusiones claras acerca del efecto de evitar las PLV durante la primera semana de vida en la prevención de la APLV. A pesar de existir datos que pudieran orientar a un cierto efecto beneficioso de su evitación en niños con riesgo atópico, estos resultados no son concluyentes ni generalizables a lactantes sin dicho riesgo.

Non-IgE-mediated cow's milk allergy is a frequent disorder in paediatrics. As patients might be seen by professionals from different specialties and levels of expertise, a great variability in diagnostic procedures and disease monitoring is commonly observed. Therefore, four scientific societies involved in its management have developed a consensus document providing specific recommendations related to its prevention, diagnosis, treatment and follow up.

Manejo de la alergia a proteína de leche de vaca por los gastroenterólogos españoles / Attitudes towards cow's milk protein allergy management by spanish gastroenterologist

INTRODUCCIÓN: La alergia alimentaria es un problema creciente, siendo la proteína de leche de vaca la principal causa en niños. Sin un proceso diagnóstico adecuado, existe un elevado riesgo de sobrediagnóstico e infradiagnóstico y, por lo tanto, de sobretratamiento e infratratamiento. El objetivo de nuestro estudio fue analizar la variabilidad en el manejo de la alergia a proteína de leche de vaca (APLV) por los gastroenterólogos pediátricos españoles. MÉTODOS: Se envió un cuestionario de 50 preguntas a través de la lista de email de la Sociedad Española de Gastroenterología, Hepatología y Nutrición Pediátricas. RESULTADOS: Recibimos 73 cuestionarios de los 321 enviados. Solo 3 de las respuestas lograron más del 90% de acuerdo. El 33% considera que la provocación oral es necesaria para el diagnóstico de APLV siempre. El 25% considera que la mejoría clínica tras la retirada de las proteínas de leche de vaca es suficiente para el diagnóstico. La provocación oral es realizada en domicilio por el 83,5% de los encuestados en APLV no IgE mediada. Los hidrolizados extensos de caseína son el tratamiento de elección (69,9%). Las fórmulas de soja, la última opción. Casi todos los encuestados conocían la existencia de guías de manejo de APLV, siendo las de la Sociedad Europea de Gastroenterología, Hepatología y Nutrición Pediátrica las más utilizadas (64,4%). El 23% considera que su conocimiento sobre alergia es inadecuado. CONCLUSIONES: Aunque la APLV es una patología prevalente que los gastroenterólogos pediátricos llevan décadas tratando, hemos encontrado una gran variabilidad en su manejo. Existe posibilidad de mejora en este campo en el futuro

INTRODUCTION: Food allergy is an increasing health problem in the developed world. Cow's milk protein is the main cause of food allergy in infants. Without an appropriate diagnostic workup, there is a high risk of both over- and underdiagnosis and therefore, over and undertreatment. The objective of our study was to analyze the variability in cow's milk protein allergy (CMPA) management by pediatric gastroenterologists in Spain. METHODS: A fifty item questionnaire, including open and closed items in a Likert's scale from 0 to 5, was drafted and distributed through the Spanish Society for Pediatric Gastroenterology, Hepatology and Nutrition (SEGHNP) e-mail list. RESULTS: Seventy-three questionnaires were received back out of 321. Only 3 of the items achieved concordance greater than 90%. Thirty-three percent considered oral challenge to be necessary for the diagnosis of CMPA under any circumstance. Twenty-five percent considered that symptom improvement after cow's milk removal was enough for the diagnosis. Oral challenge was performed at home by 83.5% in non-IgE mediated cases. Extensively hydrolyzed casein formulas were the treatment of choice for 69.9%. Soy formulas were the last option. Almost all respondents were aware of the existence of clinical guidelines on CMPA, being European Society of Pediatric Gastroenterology, Hepatology and Nutrition guidelines the most followed (64.4%). Twenty-three percent considered that their knowledge about allergy was inadequate. CONCLUSIONS: Although CMPA is a prevalent condition that pediatric gastroenterologists have been treating for decades, we found a huge variability on its management. There is potential for improvement in this field among pediatric gastroenterologist in the future

¿Cómo orientan los pediatras de Atención Primaria la alimentación complementaria? / How do primary care paediatricians guide complementary feeding in Spain?

Objetivos: evaluar las actitudes de los pediatras de Atención Primaria de nuestro medio sobre la alimentación complementaria y revisar las publicaciones relacionadas con la modalidad baby-led-weaning. Material y método: estudio descriptivo mediante la elaboración de una encuesta con 36 preguntas relacionadas con la alimentación complementaria y conocimientos sobre baby-led-weaning. Su distribución se realizó mediante correo electrónico a través de la lista de correo de la Asociación Española de Pediatría de Atención Primaria. Resultados: se analizaron los datos de 579 encuestas. El 95,3% de los pediatras emplean una hoja informativa, en un 28,6% de elaboración propia. La edad a la que recomiendan el inicio de la alimentación complementaria es en el 60,6% de los casos los seis meses, en el 24,9% los cinco meses y en el 10,7% los cuatro meses, siendo el cereal el alimento preferido para iniciarla en el 39,4% de los casos. El 61,1% aconsejan iniciar la alimentación complementaria con cuchara, el 21,4% con biberón y un 17,4% no especifica cómo hacerlo. El 54,6% aconseja la masticación tan pronto como el niño tiene interés y hasta un 10,7% no la recomienda hasta que el niño no tiene el año de edad. El 79,4% conoce la modalidad baby-led-weaning, el 45,3% la recomienda en ocasiones y un 6,6% siempre. Las principales razones para no indicarlo son la falta de información (67,2%), la escasa evidencia científica (10,6%) y el temor a que el niño presente atragantamientos (10,6%). Conclusiones: hay gran variabilidad en los consejos sobre alimentación complementaria entre los pediatras encuestados. La técnica más usada sigue siendo en nuestro medio la tradicional. Cada vez son más los pediatras que conocen la técnica del baby-led-weaning, pero pocos los que se sienten preparados para aconsejarla siempre

Objectives: to assess the attitudes of Spanish primary care paediatricians regarding complementary feeding and review the published evidence on the baby-led-weaning approach. Methods: a thirty-six item questionnaire about complementary feeding and baby-led-weaning was drafted and distributed through the Spanish Association of Primary Care Paediatricians mailing list. Results: we received 579 responses. Of all respondents, 95.3% reported using an informational handout (28.6% of their own making). Paediatricians recommended introducing complementary foods at age six months (60.6%), five months (24.9%) and four months (10.7%), and cereal was the food recommended to start complementary feeding by 39.4% of respondents. Nearly 61% of physicians recommended spoon-feeding, 21.4% bottle-feeding and 17.4% no particular feeding method. Of all respondents, 54.6% recommended giving the child foods to chew as soon as the child showed interest in it, and up to 10.7% recommended delaying it under age 1 year. Seventy-nine percent knew about baby-led-weaning, 45.3% recommended it in some cases and 6.6% routinely. The main concerns of the respondents were lack of information (67.2%), lack of scientific evidence (10.6%) and the potential risk of choking (10.6%). Conclusions: there is huge variability in the recommendations regarding complementary feeding. The approach used most frequently in Spain is the traditional one. The number of paediatricians that know about the baby-led-weaning approach is growing, but few are prepared to recommend it routinely

Características del síndrome de intestino corto y del fracaso intestinal en nuestra comunidad / Short bowel syndrome and failure intestinal features in our community

Introducción: El Fracaso intestinal está siendo una entidad con mayor prevalencia dentro de la edad pediátrica, en especial debido a resecciones importantes de intestino que terminan provocando la aparición de un Síndrome de Intestino Corto. Objetivos: Conocer la prevalencia y etiología de los casos de Síndrome de Intestino Corto (SIC) y Fracaso Intestinal (FI) existentes en la comunidad andaluza. Analizar los factores relacionados en su evolución, el número de pacientes trasplantados y conocer el tiempo necesario para lograr la autonomía enteral, estudiando si existen diferencias en el manejo entre los diferentes participantes. Métodos: Estudio observacional descriptivo retrospectivo multicéntrico en el cual se recogen los datos de los pacientes diagnosticados de Síndrome de Intestino corto o Fracaso intestinal en 6 centros hospitalarios de Andalucía en el periodo comprendido entre el 1 de enero de 2.008 y el 31 de Enero de 2.014. Resultados: 25 pacientes. Edad media al diagnóstico: 7,4 meses. Longitud media de intestino remanente 113,8 cm; 64% pacientes con <75 cm de longitud de intestino remanente. Se demuestra que: la introducción precoz de nutrición enteral es una factor favorecedor de la suspensión de la NP (p= 0’033); y que la prevención de la enfermedad hepática asociada a nutrición parenteral (EHANP) se favorece por: el uso de cifras de lípidos más bajas en la Nutrición Parenteral (p=0’008), una mayor longitud de intestino remanente (p=0’049), la introducción precoz de nutrición enteral (p=0’009) y una menor edad gestacional (p=0’006). Discusión: La Introducción precoz de NE es un factor esencial para lograr la adaptación intestinal, el destete de la NP y evitar la aparición de EHANP. Para prevenir la aparición de EHANP además de instaurar la NE lo antes posible, el manejo de los lípidos en la NP debe ser lo más exahustivo posible, intentando ajustar su aporte a las cifras más baja posibles (AU)

Introduction: Intestinal failure is being an entity with higher prevalence in the pediatric age, especially due to bowel resections causing the appearance of a short bowel syndrome. Objectives: To determine the prevalence and etiology of cases of short bowel syndrome (SIC) and Intestinal Failure (FI) existing in Andalusia. Analyze factors involved in evolution, the number of transplant patients andto know the time required to achieve enteral autonomy, studying whether there are differences in management between different participants. Methods: Multicenter retrospective descriptive observational study in which are collected data of patients diagnosed with short bowel syndrome or intestinal failure in 6 hospitals in Andalusia in the period from 1 January2008 to 31 January 2014. Results: 25 patients. Average age at diagnosis 7.4 months. Average length of remnant intestine: 113.8 cm; 64% of patients with <75 cm length remaining intestine. Weshow that: the early introduction of enteral nutrition is afactor favoring the suspension of the NP (p = 0’033); and that the prevention of liver disease associated with parenteral nutrition (EHANP) is favored by: the use of fewer lipid Parenteral Nutrition (p = 0’008), a greater length of remaining intestine (p = 0’049 ), the early introduction of enteral nutrition (p = 0’009) and a lower gestational age (p = 0’006) (AU)

Heterotopic gastric mucosa of the proximal oesophagus (inlet patch): endoscopic prevalence, histological and clinical characteristics in paediatric patients.

BACKGROUND: Heterotopic gastric mucosa is found in the proximal oesophagus, just below the upper oesophageal sphincter, and is encountered when the oesophagus is examined carefully during endoscopy. AIMS: In this study on paediatric patients, we aimed to determine the endoscopic prevalence of heterotopic gastric mucosa of the proximal oesophagus (HGMPO), to identify its macroscopic and histological characteristics and to evaluate its clinical features. PATIENTS AND METHODS: A total of 1399 patients were examined. Ages, sex, clinical and endoscopic findings of all patients were recorded. Patients with HGMPO were classified in accordance with a clinicopathological classification and information on the treatment and evolution was also recorded. RESULTS: Of the 1399 patients, 20 (11 male) were found to have HGMPO. The prevalence of HGMPO was determined to be 1.4%. In five patients, the upper oesophageal and laryngopharyngeal symptoms were remarkable. The clinicopathological classification showed that 15 patients were HGMPO type 1 (asymptomatic) and five were type 2 (symptomatic without morphologic changes). There was no significant association of any other endoscopic finding with the presence of an HGMPO. Proton pump inhibitors treatment was initiated in 16 patients, including those with HGMPO type 2. In one type 2 patient who showed no improvement during medical treatment, endoscopic treatment was indicated (argon plasma ablation). In patients with symptoms attributable to the presence of the inlet patch, the proposed treatment resolved clinical symptoms. CONCLUSION: The presence of HGMPO is not an infrequent finding in thorough endoscopies. Although HGMPO does not usually have a symptomatic progression, it can sometimes lead to supraoesophageal symptoms; thus, treatment should be considered.
