Prevalence and Risk Factors of Functional Gastrointestinal Disorders: A Cross-Sectional Study in Italian Infants and Young Children.

OBJECTIVES: Reports of prevalence of functional gastrointestinal disorders (FGIDs) in infants/toddlers are widely variable. Reasons for this variability are not yet fully understood. The objective of this study is to estimate the prevalence of FGIDs according to Rome IV criteria and to evaluate associated factors, in Italian infants and toddlers. METHODS: Subjects aged 0-48 months were enrolled by general pediatricians from 3 Italian regions. Parents or legal guardians were administered questionnaires including information about the child, the family, and GI symptoms according to Rome IV criteria. RESULTS: Five hundred eight infants aged 0-12 months [mean age 4.4 ± 3.4 months; females (F) 40.9%], and 268 children aged 13-48 months (mean age 30.8 ± 10.7 months; F 44.4%) were included. In infants, prevalence of FGIDs was 21.1%, and the most prevalent FGID was infant colic (9.3%). In toddlers, prevalence of FGIDs was 19.6%, with functional constipation being the most frequent disorder (16.1%). In infants, multivariable analysis found that being older, being the only child, and living in a rural environment were associated with a lower rate of FGIDs. Prevalence was, in contrast, higher in infants fed with formula. CONCLUSIONS: One out of 5 Italian infants and young children is affected by at least 1 FGID. The most frequent FGID in infants is infant colic, while in toddlers this is functional constipation. In infants, prevalence of FGIDs is lower if the subject has no siblings, and in children living in a rural environment, while formula feeding represents a risk factor for FGIDs occurrence.

Preventive Effect of Cow's Milk Fermented with Lactobacillus paracasei CBA L74 on Common Infectious Diseases in Children: A Multicenter Randomized Controlled Trial.

Background: Fermented foods have been proposed to prevent common infectious diseases (CIDs) in children attending day care or preschool. OBJECTIVES: To investigate the efficacy of dietary supplementation with cow's skim milk fermented with the probiotic Lactobacillus paracasei CBA L74 in reducing CIDs in children attending day care or preschool. Methods: Multicenter, randomized, double-blind, placebo-controlled trial on healthy children (aged 12-48 months) consuming daily 7 grams of cow's skim milk fermented with L. paracasei CBA L74 (group A), or placebo (maltodextrins group B) attending day care or preschool during the winter season. The main outcome was the proportion of children who experienced ≥1 episode of CID during a 3-month follow-up. Fecal biomarkers of innate (α- and ß-defensins, cathelicidin) and acquired immunity (secretory IgA) were also monitored. Results: A total of 126 children (71 males, 56%) with a mean (SD) age of 33 (9) months completed the study, 66 in group A and 60 in group B. At intention to treat analysis, the proportion of children presenting ≥1 CID was 60% in group A vs. 83% in group B, corresponding to an absolute risk difference (ARD) of -23% (95% CI: -37% to -9%, p < 0.01). At per-protocol-analysis (PPA), the proportion of children presenting ≥1 CID was 18% in group A vs. 40% in group B, corresponding to an absolute risk difference (ARD) of -22% (95% CI: -37% to -6%, p < 0.01). PPA showed that the proportion of children presenting ≥1 acute gastroenteritis (AGE) was significantly lower in group A (18% vs. 40%, p < 0.05). The ARD for the occurrence of ≥1 AGE was -22% (95% CI: -37% to -6%, p < 0.01) in group A. Similar findings were obtained at PPA regarding the proportion of children presenting ≥1 upper respiratory tract infection (URTI), which was significantly lower in group A (51% vs. 74%, p < 0.05), corresponding to an ARD of -23% (95% CI: -40% to -7%, p < 0.01). Significant changes in innate and acquired immunity biomarkers were observed only in subjects in group A. Conclusions: Dietary supplementation with cow's skim milk fermented with L. paracasei CBA L74 is an efficient strategy in preventing CIDs in children.

4p16.1-p15.31 duplication and 4p terminal deletion in a 3-years old Chinese girl: Array-CGH, genotype-phenotype and neurological characterization.

BACKGROUND: Microscopically chromosome rearrangements of the short arm of chromosome 4 include the two known clinical entities: partial trisomy 4p and deletions of the Wolf-Hirschhorn critical regions 1 and 2 (WHSCR-1 and WHSCR-2, respectively), which cause cranio-facial anomalies, congenital malformations and developmental delay/intellectual disability. METHODS/RESULTS: We report on clinical findings detected in a Chinese patient with a de novo 4p16.1-p15.32 duplication in association with a subtle 4p terminal deletion of 6 Mb in size. This unusual chromosome imbalance resulted in WHS classical phenotype, while clinical manifestations of 4p trisomy were practically absent. CONCLUSION: This observation suggests the hypothesis that haploinsufficiency of sensitive dosage genes with regulatory function placed in WHS critical region, is more pathogenic than concomitant 4p duplicated segment. Additionally clinical findings in our patient confirm a variable penetrance of major malformations and neurological features in Chinese children despite of WHS critical region's deletion.

Italian survey on general pediatricians' approach to children with gastroesophageal reflux symptoms.

UNLABELLED: The aim of the present study was to investigate the current approach of Italian general pediatricians to children with gastroesophageal reflux (GER) symptoms, evaluating the implementation of the 2009 North American Society for Pediatric Gastroenterology, Hepatology, and Nutrition (NASPGHAN)-European Society for Pediatric Gastroenterology, Hepatology, and Nutrition (ESPGHAN) guidelines. One hundred randomly identified Italian general pediatricians were asked to complete a case report-structured questionnaire investigating their approach to infants, children, and adolescents with symptoms suggestive of GER. Only 2 % of them showed complete adherence to the guidelines. Thirty-nine percent of them diagnosed GER disease based on clinical symptoms, irrespective of the age of the child; 56 % prescribed proton pump inhibitors (PPIs) in infants with unexplained crying and/or distressed behavior and 38 % in infants with uncomplicated recurrent regurgitation and vomiting; 57 % prescribed PPIs in children younger than 8-12 years of age with vomiting and heartburn, without specific testing; and 54 % discontinued PPI therapy abruptly. The overall rate of pediatricians over-prescribing PPIs was 79 %. CONCLUSION: According to our findings, most Italian general pediatricians do not seem to follow the recommendations of the 2009 NASPGHAN-ESPGHAN reflux guidelines and often prescribe PPIs despite a lack of efficacy for the symptoms being treated. We are well aware that the guidelines address the average situation and that the evaluation of individual patients may frequently reveal reasons for opening criteria for exceptions. Nevertheless, the over-diagnosis of gastroesophageal reflux disease (GERD) places undue burden on both families and national health system which has not been impacted by the publication of international guidelines.

Clinical utility of Rome criteria managing functional gastrointestinal disorders in pediatric primary care.

OBJECTIVE: Our goals were to demonstrate that functional gastrointestinal disorders (FGIDs) can be diagnosed in a positive fashion and managed by family pediatricians (FPs); to assess the compliance of FPs with a predefined diagnostic/therapeutic protocol for managing FGIDs to evaluate efficacy of continuing medical education; and to evaluate the success of reassurance by using a biopsychosocial model in comparison to drug treatment in an open-label, nonrandomized study. PATIENTS AND METHODS: A total of 9291 patients, aged birth to 14 years, were prospectively enrolled during a 3-month period by 21 FPs. Follow-up was performed at 1-, 3-, and 12-month intervals. To assess compliance, after diagnosis, FPs that participated in the study were asked to comply with the diagnostic/therapeutic protocol and record investigations and treatment prescribed. RESULTS: Two hundred sixty-one patients (2.8%) met Rome II criteria and were included in the study. In all cases but 4, diagnosis of FGIDs was confirmed at the end of follow-up (98.4%). Average compliance of FPs was >80%. Among 56 patients treated only with the explanation of symptom and reassurance, 52 (92.8%) have reported success, in comparison with 26 of 35 patients (74.3%) treated with drugs (odds ratio: 4.5 [95% confidence interval: 1.3-16]). CONCLUSIONS: FGIDs can be diagnosed and managed in primary care. Prospective studies in primary care allow assessment of compliance of pediatricians and implementation of what is learned in courses developed in continuing medical education. Informed reassurance and availability of FPs are more useful than over-the-counter drugs, which are often used for FGIDs.
