Bezlotoxumab during the first episode of Clostridioides difficile infection in patients at high risk of recurrence.

Purpose: To describe a cohort with a high risk of recurrence who received bezlotoxumab during the first episode of Clostridioides difficile infection (CDI) and to compare this cohort with patients with similar characteristics who did not receive the monoclonal antibody.

Methods: A prospective and multicentre study of patients with a high risk of recurrence (expected recurrence rate>35%) who were treated with bezlotoxumab during their first episode of CDI was conducted. A propensity score-matched model 1:2 was used to compare both cohorts that were weighed according to basal characteristics (hospital-acquisition, creatinine value, and fidaxomicin as a CDI treatment).

Long-Term Outcome of Children with Short Bowel Syndrome Treated with a Modification of the STEP Technique Avoiding Mesenteric Defect.

Background:  The Serial Transverse Enteroplasty Procedure (STEP) Registry has reported a 47% success to achieve enteral autonomy in pediatric short bowel syndrome (SBS). We have performed the STEP with a technical modification (MSTEP) consisting in stapler application without mesenteric defects that can also be applied to the duodenum. Our experience with this technique is described.

Genetic Predictors of Long-term Response to Antitumor Necrosis Factor Agents in Pediatric Inflammatory Bowel Disease.

Objectives: Inflammatory bowel disease (IBD) is more complex in children and they will have to live with the disease for much longer. For this reason, it is necessary to optimize treatment. The polymorphisms associated with the response to anti-tumor necrosis factor (TNF) drugs in adults with IBD have not been analyzed in children.

Pharmacogenetics of trough serum anti-TNF levels in paediatric inflammatory bowel disease.

Aims: Identifying DNA variants associated with trough serum anti-tumour necrosis factor (TNF) levels could predict response to treatment in inflammatory bowel disease (IBD). To date, no specific studies have been performed in children. The aim of this study was to identify genetic variants associated with trough serum anti-TNF levels and whether these variants are differential markers for infliximab and adalimumab.

Gene Signatures of Early Response to Anti-TNF Drugs in Pediatric Inflammatory Bowel Disease.

Around a 20-30% of inflammatory bowel disease (IBD) patients are diagnosed before they are 18 years old. Anti-TNF drugs can induce and maintain remission in IBD, however, up to 30% of patients do not respond. The aim of the work was to identify markers that would predict an early response to anti-TNF drugs in pediatric patients with IBD.

Food Protein-induced Enterocolitis Syndrome: Data From a Multicenter Retrospective Study in Spain.

Objective: The aim of the study was to describe clinical, epidemiological, and management characteristics of food protein-induced enterocolitis syndrome (FPIES) cases in Spain.

Patients And Methods: Multicenter observational retrospective study. FPIES cases diagnosed in specialized units in Spain over 12 months in 2017 (January-December) according to the recently published international diagnostic criteria were included.

The Role of Liver Transplantation in Propionic Acidemia.

Despite optimal medical treatment and strict low-protein diet, the prognosis of propionic acidemia (PA) patients is generally poor. We aim to report our experience with liver transplantation (LT) in the management of PA patients. Six patients with PA received a LT at a mean age of 5.

[Ledipasvir/sofosbuvir combination for chronic hepatitis C infection in children and adolescents].

Introduction: Hepatitis C virus infection is world health problem. The aim of this study was to assess the safety and efficacy of ledipasvir/sofosbuvir combination in chronic Hepatitis C Virus (HCV) genotype 1 and 4 infection in paediatric patients.

Methods: Eligible patients to be treated with ledipasvir/sofosbuvir were patients from 6 to 18 years old with a chronic HCV genotype 1 or 4 infection.

Severe renal Fanconi and management strategies in Arthrogryposis-Renal dysfunction-Cholestasis syndrome: a case report.

Background: Arthrogryposis-Renal dysfunction-Cholestasis syndrome (ARC, MIM#208085) is a rare multisystem disease due to mutations in the VPS33B and VIPAR genes, both involved in maintaining apical-basolateral cell polarity. The correlation between mutations and phenotype in the ARC Syndrome is not well described. We report on a 6 year old patient who presented with severe renal Fanconi as first manifestation of ARC related to a combined de novo mutation in the VPS33B gene.

PRESENT; PREScription of Enteral Nutrition in pediaTric Crohn's disease in Spain.

Objectives: Exclusive enteral nutrition (EEN) is one of the therapeutic strategies used to induce remission in pediatric Crohn's disease (CD). Although its use is recommended in clinical practice guidelines and consensus documents, the frequency of this practice in Spain is unknown.

Methods: A 70-item questionnaire (

Present: PREScription of Enteral Nutrition in pediaTric Crohn's disease in Spain) was drafted and distributed through the SEGHNP (Spanish Society for Pediatric Gastroenterology, Hepatology and Nutrition) e-mail list.

Modification of stool's water content in constipated infants: management with an adapted infant formula.

Background: Constipation is a common occurrence in formula-fed infants. The aim of this preliminary study was to evaluate the impact of a formula with high levels of lactose and magnesium, in compliance with the official regulations, on stool water content, as well as a parental assessment of constipation.

Materials And Methods: Thirty healthy term-born, formula-fed infants, aged 4-10 weeks, with functional constipation were included.

Dietary treatment of colic caused by excess gas in infants: biochemical evidence.

Aim: To evaluate the impact of feeding colicky infants with an adapted formula on the hydrogen breath test and clinical symptoms.

Methods: Hydrogen expiration was measured by SC MicroLyzer gas chromatography at inclusion and 15 d after treatment with an adapted low-lactose formula in 20 colicky infants.

Results: All babies were symptomatic: 85% with excess gas, 75% with abnormal feeding pattern, and 85% with excessive crying.

Effects of cocaine administration on VTA cell activity in response to prefrontal cortex stimulation.

The repeated use of psychostimulants in humans has been associated with progressive enhancement of anxiety, panic attacks, and eventually paranoid psychosis. The appearance of such behaviors has been termed behavioral sensitization, which forms part of the basic pathological mechanisms involved in drug addiction. Psychostimulants act via a circuit involving the ventral tegmental area (VTA), prefrontal cortex (PFC), and nucleus accumbens.

Effects of intravenous cocaine administration on cerebellar Purkinje cell activity.

The goal of the present study was to investigate the effects of intravenous cocaine administration on cerebellar Purkinje cell firing. Extracellular neuron activity was recorded and cells were locally excited with spaced microiontophoretic pulses of glutamate. Glutamate-evoked and spontaneous discharges were compared before and immediately following cocaine administration.

Chronic imipramine treatment induces downregulation of alpha-2 receptors in rat's locus coeruleus and A2 region of the tractus solitarius.

Imipramine is an effective antidepressant agent that blocks the reuptake of monoamines. In order to understand some of its basic mechanisms of action, we investigated the effects of chronic imipramine administration (10 mg/kg, i.p.
