Alterations in One-Carbon Metabolism in Celiac Disease
Celiac disease (CD) is an autoimmune enteropathy associated with alterations of
metabolism. Metabolomics studies, although limited, showed changes in choline, choline-derived
lipids, and methionine concentrations, which could be ascribed to alterations in one-carbon metabolism.
To date, no targeted metabolomics analysis investigating di erences in the plasma choline/methionine
metabolome of CD subjects are reported. This work is a targeted metabolomic study that analyzes
37 metabolites of the one-carbon metabolism in 17 children with CD, treated with a gluten-free diet
and 17 healthy control siblings, in order to establish the potential defects in this metabolic network.
Our results demonstrate the persistence of defects in the transsulfuration pathway of CD subjects,
despite dietary treatment, while choline metabolism, methionine cycle, and folate cycle seem to be
reversed and preserved to healthy levels. These findings describe for the first time, a metabolic defect
in one-carbon metabolism which could have profound implications in the physiopathology and
treatment of CD.Junta de AndalucĂa

Proactive monitoring of anti-TNF agents improves follow-up of paediatric patients with Crohn disease
Introduction and aims: The incidence of paediatric inflammatory bowel disease has increased in recent decades. The aim of the present study was to evaluate the role of proactive and serial monitoring of tumour necrosis factor (TNF) inhibitor levels to maintain clinical remission and mucosal healing in the follow-up of paediatric patients with Crohn disease (CD).Method: Prospective study that included all patients diagnosed with CD and treated with adali-mumab or infliximab between May 2015 and November 2020 who underwent serial and proactive monitoring of TNF inhibitor levels.Results: The study included 30 patients, 21 male (70%). The mean age at diagnosis was 11.3 years (SD, 2.0), the mean age at initiation of TNF inhibitors was 12.6 years (SD, 1.9) with a mean duration of follow-up of 27.1 +/- 9.1 months. Clinical remission was defined as a weighted Pediatric Crohn's Disease Activity Index (wPCDAI) of less than 12.5 and mucosal healing as a Mucosal Inflammation Non-invasive Index (MINI) of less than 8. During the follow-up, patients were in clinical remission in 87.1% of the visits, presented with mild disease in 11.4% and with moderate disease in 1.5%, and mucosal healing was assumed in 83% of the visits. The rates of clinical remission and mucosal healing at 1, 2, and 3 years of follow-up were 83.3%, 95.8%, 92.8%, and 86.7%, 87.5% and 85.7%, respectively. Conclusions: Proactive and serial monitoring of serum TNF inhibitor levels may make it possible for patients to maintain clinical remission and mucosal healing in the maintenance phase, with individualised optimization of the required dosage and minimization of secondary loss of response.(c) 2022 Asociacion Espanola de Pediatria.

Time Following a Gluten-Free Diet, Ultra-Processed Food Consumption and Quality of Life in Children with Celiac Disease
Featured Application The data from the present study indicate that nutritionists and other healthcare professionals should monitor the quality of life and diet quality of children with celiac disease, especially from the first year of treatment with a gluten-free diet. Maintaining a strict gluten-free diet (GFD) may affect the quality of life of children with celiac disease (CD) and promote a less healthy diet by substituting gluten-containing foods with ultra-processed foods. We aimed to assess the influences of the GFD and ultra-processed food consumption on parents' perception of the quality of life of children with CD. Fifty-eight children (mean age 8.6 +/- 4.1 years) were included. The participants were divided into groups based on the time following a GFD: = 12 months (n = 37). Their dietary consumption was assessed through a three-day food record. The 20-item Celiac Disease Quality Of Life survey (CD-QOL), which contains four subscales (limitations, dysphoria, health concerns, and inadequate treatment) was used to assess the quality of life. The children who followed a GFD for >= 12 months presented poorer scores in the limitations subscale than those who followed a GFD for = 12 months presented poorer scores in the limitations subscale than those who followed a GFD fo
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 alt 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.

Spanish Pediatric Inflammatory Bowel Disease Diagnostic Delay Registry: SPIDER Study From Sociedad Española de GastroenterologĂa, HepatologĂa y NutriciĂłn Pediátrica.
Background and Aims: Diagnostic delay (DD) is especially relevant in children with inflammatory bowel disease, leading to potential complications. We examined the intervals and factors for DD in the pediatric population of Spain. Methods: We conducted a multicentric prospective study, including 149 pediatric inflammatory bowel disease patients, obtaining clinical, anthropometric, and biochemical data. Time to diagnosis (TD) was divided into several intervals to identify those where the DD was longer and find the variables that prolonged those intervals. Missed opportunities for diagnosis (MODs) were also identified. Results: Overall TD was 4.4 months (interquartile range [IQR] 2.6-10.4), being significantly higher in Crohn's disease (CD) than in ulcerative colitis (UC) (6.3 [IQR 3.3-12.3] vs. 3 [IQR 1.6-5.6] months, p = 0.0001). Time from the visit to the first physician until referral to a pediatric gastroenterologist was the main contributor to TD (2.4 months [IQR 1.03-7.17] in CD vs. 0.83 months [IQR 0.30-2.50] in UC, p = 0.0001). One hundred and ten patients (78.3%) visited more than one physician (29.9% to 4 or more), and 16.3% visited the same physician more than six times before being assessed by the pediatric gastroenterologist. The number of MODs was significantly higher in CD than that in UC patients: 4 MODs (IQR 2-7) vs. 2 MODs ([IQR 1-5], p = 0.003). Referral by pediatricians from hospital care allowed earlier IBD diagnosis (odds ratio 3.2 [95% confidence interval 1.1-8.9], p = 0.025). Conclusions: TD and DD were significantly higher in CD than those in UC. IBD patients (especially those with CD) undergo a large number of medical visits until the final diagnosis
