Cytomegalovirus erosive gastritis in a healthy infant: update about a case

El citomegalovirus es un virus ADN de la familia Herpesviridae que puede afectar al tubo digestivo. Dentro de éste, las dianas de afectación suelen ser el colon, el esófago y el estómago. Se ha descrito ampliamente su asociación con el síndrome de Ménétrier (hiperplasia foveolar con pérdida de proteínas), si bien también puede producir cuadros de gastritis erosiva. En el presente artículo se describe un caso de gastritis erosiva en una lactante sana de 4 meses de edad, que se inició en forma de hemorragia digestiva alta. A partir de este caso, se lleva a cabo una puesta al día de este subgrupo de infecciones por citomegalovirusCytomegalovirus is a DNA Herpesviridae family which can affect the digestive tract. From the standpoint of the stomach, has been widely described his association with Ménétrier syndrome (foveolar hyperplasia with protein-losing) but can also produce erosive gastritis. This article describes a case of erosive gastritis in a healthy 4 months infant which debuted as upper gastrointestinal bleeding. In addition we perform an update of this subgroup of cytomegalovirus infection

Increasing Incidence of Pediatric Eosinophilic Esophagitis in the Southwest of Madrid, Spain.

Objectives: The incidence of eosinophilic esophagitis is unknown in our area. The aim of our study was to determine the incidence of eosinophilic esophagitis and its possible association with the most frequent absolute annual pollen counts. Methods: A descriptive retrospective multicenter observational study was designed to calculate the incidence of eosinophilic esophagitis in children aged under 15 years in the southwest region of Madrid, Spain in 2002-2013 (data were provided by the Statistics Institute of Madrid). We collected data on age, sex, clinical presentation, and date of endoscopic diagnosis. Relative risk (RR) was estimated (Stata v.11) using negative binomial regression models to assess the association between incidence and pollen counts (provided by Subiza Clinic). Results: The study population comprised 254 patients (192 male [75.6%], aged 0.5-14.99 years). The clinical presentation was esophageal impaction in 23.6%, dysphagia in 22%, gastroesophageal reflux–like symptoms in 44.9%, and other findings in 9.4%. The annual incidence from 2002 to 2013 per 100 000 children aged <15 years per year was, respectively, 0.81, 1.5, 0.37, 3.17, 3.07, 4.36, 6.87, 7.19, 8.38, 9.05, 9.14, and 9.68. The incidence of eosinophilic esophagitis increased by an average of 19% annually (RR, 1.19; 95%CI, 1.14-1.25;P1 (1.17 and 1.06, respectively) (P<.05). Conclusion: The incidence of diagnosis of pediatric eosinophilic esophagitis increased by an average of 19% annually. No significant association was found between incidence and pollen counts, except for a weak association with Platanus species.post-print359 K

Predictors of Response to Exclusive Enteral Nutrition in Newly Diagnosed Crohn´s Disease in Children: PRESENCE Study from SEGHNP

Exclusive enteral nutrition (EEN) has been shown to be more effective than corticosteroids in achieving mucosal healing in children with Crohn´s disease (CD) without the adverse effects of these drugs. The aims of this study were to determine the efficacy of EEN in terms of inducing clinical remission in children newly diagnosed with CD, to describe the predictive factors of response to EEN and the need for treatment with biological agents during the first 12 months of the disease. We conducted an observational retrospective multicentre study that included paediatric patients newly diagnosed with CD between 2014–2016 who underwent EEN. Two hundred and twenty-two patients (140 males) from 35 paediatric centres were included, with a mean age at diagnosis of 11.6 ± 2.5 years. The median EEN duration was 8 weeks (IQR 6.6–8.5), and 184 of the patients (83%) achieved clinical remission (weighted paediatric Crohn’s Disease activity index [wPCDAI] 15 mg/L and ileal involvement tended to respond better to EEN. EEN administered for 6–8 weeks is effective for inducing clinical remission. Due to the high response rate in our series, EEN should be used as the first-line therapy in luminal paediatric Crohn’s disease regardless of the location of disease and disease activityS

Role of age and comorbidities in mortality of patients with infective endocarditis

Purpose: The aim of this study was to analyse the characteristics of patients with IE in three groups of age and to assess the ability of age and the Charlson Comorbidity Index (CCI) to predict mortality. Methods: Prospective cohort study of all patients with IE included in the GAMES Spanish database between 2008 and 2015. Patients were stratified into three age groups:<65 years, 65 to 80 years, and = 80 years.The area under the receiver-operating characteristic (AUROC) curve was calculated to quantify the diagnostic accuracy of the CCI to predict mortality risk. Results: A total of 3120 patients with IE (1327 < 65 years;1291 65-80 years;502 = 80 years) were enrolled.Fever and heart failure were the most common presentations of IE, with no differences among age groups.Patients =80 years who underwent surgery were significantly lower compared with other age groups (14.3%, 65 years; 20.5%, 65-79 years; 31.3%, =80 years). In-hospital mortality was lower in the <65-year group (20.3%, <65 years;30.1%, 65-79 years;34.7%, =80 years;p < 0.001) as well as 1-year mortality (3.2%, <65 years; 5.5%, 65-80 years;7.6%, =80 years; p = 0.003).Independent predictors of mortality were age = 80 years (hazard ratio [HR]:2.78;95% confidence interval [CI]:2.32–3.34), CCI = 3 (HR:1.62; 95% CI:1.39–1.88), and non-performed surgery (HR:1.64;95% CI:11.16–1.58).When the three age groups were compared, the AUROC curve for CCI was significantly larger for patients aged <65 years(p < 0.001) for both in-hospital and 1-year mortality. Conclusion: There were no differences in the clinical presentation of IE between the groups. Age = 80 years, high comorbidity (measured by CCI), and non-performance of surgery were independent predictors of mortality in patients with IE.CCI could help to identify those patients with IE and surgical indication who present a lower risk of in-hospital and 1-year mortality after surgery, especially in the <65-year group

Retraso de la adquisición de la succión-deglución-respiración en el pretérmino: efectos de una estimulación precoz Delay in the acquisition of sucking-swallowing-breathing in the preterm: efects of early stimulation

Introducción: La nutrición oral del prematuro no es posible hasta la adquisición del reflejo de la succión-deglución-respiración. Su retraso prolonga la estancia hospitalaria y aumenta la incidencia de trastornos oro-motores en los primeros años de la infancia. Objetivos: Analizar la transición de la nutrición enteral a la oral, la comorbilidad asociada con su retraso y el impacto de una estimulación precoz de la succión en una cohorte de prematuros. Pacientes y métodos: Revisión retrospectiva de 95 prematuros menores de 32 semanas de gestación (SG) ingresados en una UCI neonatal en los últimos 4 años. Se revisó la edad gestacional, somatometría al nacimiento y al alta, comorbilidad asociada, duración de la ventilación mecánica, necesidades de oxígeno, momento de inicio/fin de nutrición enteral/oral, inicio del método canguro y estimulo de la succión y ganancia ponderal media diaria. Resultados: La estimulación de la succión se inició entre la semana 29 y 40 SG (media y mediana 32 SG). La nutrición oral se inició entre la 31-40 SG (media y mediana 33SG) y completó entre la 33-44 SG (media y mediana 35 SG). La nutrición oral se retrasó en los pacientes que necesitaron más tiempo de ventilación mecánica y oxigenoterapia. Hubo una correlación positiva entre el inicio de la estimulación de la succión y el momento de adquisición de una nutrición oral completa (84% test de correlación de Spearman) y el tiempo de estancia hospitalaria (80% test de correlación de Spearman). Conclusiones: El estímulo precoz de la succión en el paciente pretérmino parece facilitar la nutrición oral completa de manera precoz, asociándose a una disminución en la estancia hospitalaria y a una mejora en la ganancia ponderal media diaria.Introduction: Premature baby's oral feeding is not possible until the reflex of sucking-swallowing-breathing adquisition. Its delay extends hospital stay and increases the incidence of oral motor disorders in early childhood. Aims: To analyze the transition from enteral to oral nutrition, the comorbidity associated with its delay and the impact of an early suction stimulation in a cohort of premature babies. Patients and methods: Retrospective checking of 95 infants less than 32 gestation weeks (GW) admitted to a neonatal ICU in the last 4 years. It was revised the gestational age, anthropometric at birth and discharge, comorbidity, duration of mechanical ventilation, oxygen requirements, time of beginning and end of enteral/oral nutrition, beginning of Kangaroo method and the suction stimulation and the daily weight gain average. Results: Suction stimulation began between weeks 29 and 40 GW (average and median 32 GW). Oral nutrition was initiated between 31-40 GW (average and median 33 GW) and completed between 33-44 GW (average and median 35 GW). Oral nutrition was delayed in patients who required longer mechanical ventilation and oxygen therapy. There was a positive correlation between the beginning of suction stimulation and the time of acquisition of a complete oral nutrition (84% Spearman correlation test) and length of hospital stay (80% Spearman correlation test). Conclussions: Early suction stimulation in a preterm patient seems to facilitate full oral nutrition at an early stage and it is associated with a hospital stay decrease and the improvement in the daily weight gain average

Pathogenesis and endoscopic findings in H. pylori infection in children

La infección por Helicobacter pylori es una de las causas más frecuentes de infección bacteriana crónica en el ser humano. A través de distintos factores patogénicos (adhesinas, ureasa, proteínas citotóxicas cagA y vacA) puede producir cambios que se pueden apreciar en una endoscopia digestiva alta. Estos incluyen la aparición de lesiones ulcerosas, mucosa en empedrado y palidez alternando con eritema, entre otros. Sus dianas preferentes en la edad pediátrica son el antro gástrico y el duodeno proximal. Este artículo hace una revisión de los hallazgos endoscópicos relacionados con la infección por H. pylori en niños, así como de sus posibles causas y consecuencias clínicasH. pylori infection is one of the most frequent chronic bacterial infections in human beings. Through different pathogenic factors (adhesins, urease, cagA and vacA cytotoxic proteins) it may produce mucosal changes that can be seen in an upper gastrointestinal endoscopy. These changes include, among others, ulcerative lesions, cobblestone mucosa and pallor alternating with erythema. Its favorite targets in children are the gastric antrum and proximal duodenum. This article reviews the endoscopic findings related to H. pylori infection in children and their possible causes and clinical consequence
