ABSTRACT
OBJECTIVES: Patients with inflammatory bowel disease (IBD) tend to self-modify their dietary habits according to disease activity and symptoms. This study aimed to assess the adequacy of the usual diet in Italian children with IBD in comparison to a control group and to the recommended dietary allowances (RDA). METHODS: Dietary habits of IBD children and age- and gender-matched healthy controls were investigated using a validated Food Frequency Questionnaire in five Italian pediatric IBD centers. Adherence to the Mediterranean diet (MD) was assessed using the KID-MED test. Energy (EI), macro, and micronutrients intakes were compared between the two groups, to the RDA and the predicted total energy expenditure (EI/total energy expenditure [TEE]%). RESULTS: IBD subjects (n = 110) reported a lower EI, EI/RDA%, and EI/TEE% compared to controls (n = 110) (p = 0.012, p < 0.0002, and p = 0.014), lower total protein and fat intakes (p = 0.017, p < 0.0001) and lower minerals/RDA, vitamins/RDA and micronutrients/RDA ratio (%). Poor adherence to the MD was more frequent in IBD children compared to controls (p = 0.013). The total EI and carbohydrate intake were inversely correlated with higher disease activity. CONCLUSIONS: Italian children with IBD report an inadequate diet in terms of energy, macro, and micronutrients and have a low adherence to a high-quality MD pattern.
ABSTRACT
BACKGROUND: The relationship between Helicobacter-pylori(Hp)infection and inflammatory-bowel-disease(IBD) in pediatric-patients remains controversial. We aimed to assess the Hp-infection occurrence in newly-diagnosed pediatric-patients with IBD compared to no-IBD patients. Additionally, we aimed to examine differences in clinical-activity-index(CAI) and endoscopic-severity-score(ESS)between IBD-patients with and without Hp-infection, at baseline and at 1-year-follow-up(FU), after eradication-therapy(ET). METHODS: IBD diagnosis was based on Porto-criteria, and all patients underwent gastroscopy at baseline and 1-year FU. For Crohn's-disease(CD) and ulcerative colitis(UC), IBD-CAI and -ESS were classified using PCDAI/SES-CD and PUCAI/UCEIS, respectively. RESULTS: 76 IBD-patients were included in the study[35 F(46.1%),median-age 12(range 2-17)]. CD and UC were diagnosed in 29(38.2%) and 45(59.2%)patients, respectively, and unclassified-IBD in two(2.6%)patients. Non-IBD patients were 148[71 F(48.0%),median-age 12(range 1-17)]. Hp-infection at baseline was reported in 7(9.2%) and 18(12.2%)IBD and non-IBD patients, respectively(p = 0.5065). The 7 IBD patients with Hp infection were compared to 69 IBD patients without Hp-infection at baseline evaluation, and no significant differences were reported considering CAI and ESS in these two groups. At 1-year FU, after ET, IBD patients with Hp infection improved, both for CAI and ESS, but statistical significance was not reached. CONCLUSION: The occurrence of Hp-infection did not differ between IBD and no-IBD patients. No differences in CAI or ESS were observed at the diagnosis, and after ET no worsening of CAI or ESS was noted at one-year FU, between Hp-positive and -negative IBD patients.

INTRODUCTION: Debate exists regarding the ideal timing for surgery in Hirschsprung disease (HSCR) in various groups of age. The aim of this paper was to suggest a possible strategy to determine the optimal timing for reconstructive surgery in patients affected by HSCR. EVIDENCE ACQUISITION: A systematic literature search of papers published on PubMed and Embase during the last decade, addressing "Hirschsprung," "preoperative enterocolitis," "preoperative mortality," "complications," and "timing" in all possible combinations, was performed. EVIDENCE SYNTHESIS: A total of 10 out of 170 identified papers addressed this issue in detail and were subsequently assessed for in-depth analysis. Our review confirmed that the most important issue to guide surgical timing is represented by HSCR Associated Enterocolitis (HAEC). Most authors suggest performing pull-through at around 3 months of age after effective bowel decompression, which should not be continued indefinitely to avoid complications. CONCLUSIONS: Based on this systematic review we suggest the following: 1) healthy neonates should undergo surgical reconstruction at 3 months of age; 2) urgent surgery (levelling enterostomy) might be required in critically unwell patients, those with Total Colonic HSCR, or those in whom nursing proved to be ineffective; 3) surgery can be safely postponed only in older patients with a lower likelihood of HAEC (i.e. without previous HAEC occurrences) always avoiding long-lasting rectal irrigations.
ABSTRACT
OBJECTIVE: This study aimed to evaluate the efficacy and safety of co-micronized palmitoylethanolamide (PEA)/polydatin (PD) in the treatment of abdominal pain symptoms in pediatric patients with irritable bowel syndrome (IBS). METHODS: This was a multicenter trial conducted at three Italian pediatric gastroenterology centers, employing a double-blind, placebo-controlled, parallel-arm design. Participants were ages 10 to 17 y and met Rome IV criteria for pediatric IBS. They were randomly allocated to receive either co-micronized PEA/PD or placebo, administered three times daily in a 1:1 ratio, over a 12-wk period. The study assessed baseline severity using the IBS-Severity Scoring System (IBS-SSS) at enrollment and after 4, 8, and 12 wk of treatment. Abdominal pain frequency was assessed on a scale from 1 to 7 d/wk, while stool consistency was classified using the Bristol Stool Scale (BSS) to categorize various IBS subtypes. The primary outcome was the percentage of patients who achieved complete remission, defined as IBS-SSS score <75 points after 12 wk of therapy. RESULTS: The study involved 70 children with IBS. Of the participants, 34 received co-micronized PEA/PD, and 36 received a placebo. As compared with the placebo group, the co-micronized therapy group had significantly more patients achieving complete remission after 12 wk (P = 0.015), with particular benefit in the IBS-diarrhea subtype (P = 0.01). The treatment group also experienced a significant reduction in abdominal pain intensity and frequency compared with the placebo group. No adverse events were recorded during the study period. CONCLUSIONS: Co-micronized PEA/PD is a safe and effective treatment to treat abdominal pain symptoms in pediatric IBS.

BACKGROUND: Pediatric chronic intestinal pseudo-obstruction (PIPO) is a rare disease characterized by symptoms and radiological signs suggestive of intestinal obstruction, in the absence of lumen-occluding lesions. It results from an extremely severe impairment of propulsive motility. The intestinal endocrine system (IES) jointly with the enteric nervous system (ENS) regulates secreto-motor functions via different hormones and bioactive messengers/neurotransmitters. The neurotransmitter 5-hydroxytryptamine (5-HT) (or serotonin) is linked to intestinal peristalsis and secretory reflexes. Gut microbiota and its interplay with ENS affect 5-HT synthesis, release, and the subsequent serotonin receptor activation. To date, the interplay between 5-HT and gut microbiota in PIPO remains largely unclear. This study aimed to assess correlations between mucosa associated microbiota (MAM), intestinal serotonin-related genes expression in PIPO. To this purpose, biopsies of the colon, ileum and duodenum have been collected from 7 PIPO patients, and 7 age-/sex-matched healthy controls. After DNA extraction, the MAM was assessed by next generation sequencing (NGS) of the V3-V4 region of the bacterial RNA 16 S, on an Illumina Miseq platform. The expression of genes implicated in serotoninergic pathway (TPH1, SLC6A4, 5-HTR3 and 5-HTR4) was established by qPCR, and correlations with MAM and clinical parameters of PIPO have been evaluated. RESULTS: Our results revealed that PIPO patients exhibit a MAM with a different composition and with dysbiosis, i.e. with a lower biodiversity and fewer less connected species with a greater number of non-synergistic relationships, compared to controls. qPCR results revealed modifications in the expression of serotonin-related intestinal genes in PIPO patients, when compared to controls. Correlation analysis do not reveal any kind of connection. CONCLUSIONS: For the first time, we report in PIPO patients a specific MAM associated to underlying pathology and an altered intestinal serotonin pathway. A possible dysfunction of the serotonin pathway, possibly related to or triggered by an altered microbiota, may contribute to dysmotility in PIPO patients. The results of our pilot study provide the basis for new biomarkers and innovative therapies targeting the microbiota or serotonin pathways in PIPO patients.

BACKGROUND: The natural history of ulcerative proctitis (UP) has been poorly investigated in children. AIMS: We aimed to compare the disease course of children with UP at diagnosis to the other locations and to identify extension predictors. METHODS: This was a multicenter, observational study carried out from data prospectively entered in the SIGENP-IBD-Registry. Children with ulcerative colitis (UC) diagnosis and at least 1-year follow-up were included. On the basis of Paris classification UP patients were identified and compared with the other locations. RESULTS: 872 children were enrolled (median age at diagnosis: 11.2 years; M/F: 426/446), of whom 78 (9%) with UP. Kaplan-Meier analysis demonstrated increased cumulative probabilities of disease extension in the E1 group [1 year: 20.3%; 5 years: 52.7%; 10 years: 72.4%] compared to E3 group [1 year: 8.5%; 5 years: 24.9% and 10 years: 60.1%, p=0.001]. No differences were observed comparing E1 and E2 groups [p=0.4]. Cumulative probabilities of surgery at 1, 5 and 10 years were 1.3, 2.8 and 2.8% in the E1 group and 2.5, 8 and 12.8% in the E2-E3-E4 group, respectively (p=0.1). Cox regression analysis demonstrated that PUCAI>35 at diagnosis was associated with endoscopic extension (HR=4.9; CI 95% 1.5-15.2, p=0.006). CONCLUSIONS: UP is associated with similar short and long-term outcomes compared to other locations.

BACKGROUND AND AIMS: Foreign body ingestion (FBI) in children requires early identification to prevent adverse outcomes and may necessitate endoscopic or surgical intervention. This study aims to develop a nomogram that identifies children who require urgent surgical or endoscopic intervention by using the patient's medical history and clinical parameters collected at admission. METHODS: This study is a retrospective review (01/2015-12/2020) of a multicenter case series of children admitted for FBI. Data from 5864 records from 24 hospitals in Italy were analyzed. Logistic regression models were used to establish the probability of requiring surgical or endoscopic intervention based on patient history and clinical characteristics. The nomogram representing the results from the multivariable model was reported to examine the propensity for surgery/endoscopy. RESULTS: The study identified a significant association between intervention and various factors, including type of foreign body (blunt: reference category, disk battery (odds ratio OR:4.89), food bolus (OR:1.88), magnets (OR:2.61), sharp-pointed (OR:1.65), unknown (OR:1.02)), pre-existing diseases or conditions (OR 3.42), drooling (OR 10.91), dysphagia (OR 5.58), vomiting (OR 3.30), retrosternal pain (OR 5.59), abdominal pain (OR 1.58), hematemesis (OR 2.82), food refusal/poor feeding (OR 2.99), and unexplained crying (OR 2.01). The multivariable regression model showed good calibration and discrimination ability, with an area under the ROC curve of 0.77. CONCLUSIONS: This study developed the first nomogram to predict the probability of the need for surgical or endoscopic intervention in children with FBI, based on the information collected at admission. The nomogram will aid clinicians in identifying children who require early intervention to prevent adverse outcomes.

Lifelong adherence to a gluten-free diet (GFD) is the cornerstone of management of celiac disease (CD), but adhering to a GFD can be hard. Although several factors are positively associated with adherence of pediatric CD patients to a GFD, it is unknown whether these are influenced by variability caused by the specific tool used to assess adherence to a GFD. Here, we aimed to evaluate how individual patient characteristics and dietary counselling by a trained dietitian influence adherence to a GFD in children with CD, as assessed by two validated questionnaires: the Biagi questionnaire and the Leffler short questionnaire adapted for pediatric patients. Some 139 children and adolescents were recruited in a cross-sectional, multicenter study. Concordance between the two questionnaires in defining adherence was fair (weighted Cohen's kappa coefficient 0.39, 95%CI 0.19-0.60). Upon regression analysis, having a cohabiting family member with CD, being of Italian origin, and receiving specialized dietary counselling during follow-up were found to positively influence stricter adherence to a GFD for children with CD. Neither questionnaire detected a significant relationship between adherence to a GFD and the presence of symptoms after gluten ingestion. This study provides important new data on the factors influencing GFD adherence in the pediatric population, and highlights the importance of dietician input and overcoming language and cultural barriers when educating patients.

Background/Aims: Since available data on pediatric non-erosive esophageal phenotypes (NEEPs) are scant, we investigated their prevalence and the phenotype-dependent treatment response in these children. Methods: Over a 5-year period, children with negative upper endoscopy, who underwent esophageal pH-impedance (off-therapy) for persisting symptoms not responsive to proton pump inhibitor (PPI)-treatment, were recruited. Based on the results of acid reflux index (RI) and symptom association probability (SAP), patients were categorized into: (1) abnormal RI (non-erosive reflux disease [NERD]), (2) normal RI and abnormal SAP (reflux hypersensitivity [RH]), (3) normal RI and normal SAP (functional heartburn [FH]), and (4) normal RI and not-reliable SAP (normal-RI-not otherwise-specified [normal-RI-NOS]). For each subgroup, treatment response was evaluated. Results: Out of 2333 children who underwent esophageal pH-impedance, 68 cases, including 18 NERD, 14 RH, 26 FH, and 10 normal-RI-NOS were identified as fulfilling the inclusion criteria and were analyzed. Considering symptoms before endoscopy, chest pain was more reported in NERD than in other cases (6/18 vs 5/50, P = 0.031). At long-term follow-up of 23 patients (8 NERD, 8 FH, 2 RH, and 5 normal-RI-NOS): 17 were on PPIs and 2 combined alginate, 1 (FH) was on benzodiazepine + anticholinergic, 1 (normal-RI-NOS) on citalopram, and 3 had no therapy. A complete symptom-resolution was observed in 5/8 NERD, in 2/8 FH, and in 2/5 normal-RI-NOS. Conclusions: FH may be the most common pediatric NEEP. At long-term follow-up, there was a trend toward a more frequent complete symptom resolution with PPI-therapy in NERD patients while other groups did not benefit from extended acid-suppressive-treatment.
ABSTRACT
The restrictive measures adopted worldwide against SARS-CoV-2 produced a drastic reduction in respiratory pathogens, including RSV, but a dramatic rebound was thereafter reported. In this multicenter retrospective observational study in 15 Pediatric Emergency Departments, all children <3 years old with RSV infection admitted between 1 September and 31 December 2021 were included and compared to those admitted in the same period of 2020 and 2019. The primary aim was to evaluate RSV epidemiology during and after the COVID-19 pandemic peak. The secondary aims were to evaluate the clinical features of children with RSV infection. Overall, 1015 children were enrolled: 100 in 2019, 3 in 2020 and 912 in 2021. In 2019, the peak was recorded in December, and in 2021, it was recorded in November. Comparing 2019 to 2021, in 2021 the median age was significantly higher and the age group 2-3 years was more affected. Admissions were significantly higher in 2021 than in 2020 and 2019, and the per-year hospitalization rate was lower in 2021 (84% vs. 93% in 2019), while the duration of admissions was similar. No difference was found in severity between 2019-2020-2021. In conclusion, after the COVID-19 pandemic, an increase in RSV cases in 2021 exceeding the median seasonal peak was detected, with the involvement of older children, while no difference was found in severity.

OBJECTIVES: Polyethylene glycol (PEG) split-dose regimen is recommended as the option of choice for colon preparation before colonoscopy in children and adults. Sodium picosulfate plus magnesium citrate (SPMC) is equally effective but better tolerated than PEG for bowel preparation before colonoscopy in children. The aim of this study was to assess the superiority of SPMC split-dose regimen compared with SPMC day-before regimen for bowel cleansing before colonoscopy in children. METHODS: This was a multicenter, randomized, single-blind study. Pediatric inpatients undergoing colonoscopy received SPMC either in the day-before dosing or in split dosing. Overall bowel cleansing was assessed using the Boston Bowel Preparation Scale (BBPS) and was rated as successful when BBPS was ≥6. Patient tolerability, acceptability, and compliance were recorded. RESULTS: The rate of successful cleansing level was significantly higher in the split-dose group than in the day-before group (P < 0.001). The BBPS scores were significantly higher in the split-dose group than in the day-before group for the whole colon (P < 0.001), the right colon (P < 0.001) and transverse colon (P < 0.001). Patient acceptability was better in the split-dose group (P = 0.0003; P = 0.005). The percentage of children needing nasogastric tube placement was better in the split-dose group (P = 0.007). CONCLUSIONS: The split-dose regimen of SPMC was superior to the day-before regimen in terms of successful colon cleansing and acceptability.

BACKGROUND: Scarce data have investigated the association between pediatric inflammatory bowel disease (IBD) and eosinophilic esophagitis (EoE). We, therefore, aimed to describe the epidemiology and the possible peculiar phenotype and natural history of such an association. METHODS: Case-control study is based on the Italian Society for Pediatric Gastroenterology (SIGENP) national registry. All children with a combined diagnosis of IBD and EoE were included. The overall prevalence and incidence in 2 periods, 2009 to 2015, and 2016 to 2021, were calculated. Cases were matched with IBD only and EoE only patients in a 1:3:3 ratio. Phenotype and outcomes (courses of steroids, risk of complications, surgery, treatment escalation, and hospitalization) were compared between groups. RESULTS: Eleven patients (age 11.2â ±â 2.8 years, Males 91%) with EoE-IBD out of 3090 patients with IBD were identified, resulting in an overall prevalence of 0.35% and an incidence of 0.18% for 2009 to 2015 and 0.45% for 2016 to 2021. Treatment escalation rates for IBD were significantly higher in patients with IBD compared with EoE-IBD at 12- and 24-month follow-up (0% vs 30%, Pâ =â .04; and 9% vs 45.5%, Pâ =â .03, respectively). Furthermore, patients with IBD were at a significantly higher risk of hospitalization than both EoE-IBD and EoE patients (log rank Pâ <â .001). We found no significant differences in major outcomes related to the EoE course in EoE-IBD patients compared with EoE ones. CONCLUSIONS: The incidence and prevalence of EoE in children with IBD are low, although the incidence seems to be rising in recent years. Having EoE appears to be associated with a milder IBD disease course, whereas having IBD does not seem to affect the natural history of EoE. More data are needed to better define the phenotype of such association.
We investigated the association between pediatric inflammatory bowel disease (IBD) and eosinophilic esophagitis (EoE). Our results showed that having an EoE might be associated with a milder IBD disease course, but larger cohort analyses are needed to confirm such result.

BACKGROUND: IBS affects a large number of children throughout the world and is thought to be the result of disturbed neuroimmune function along with the brain-gut axis. Although the underlying pathophysiologic mechanisms are not clear, the role of low-grade inflammation and mucosal immune activation in IBS symptom generation has become evident also in subsets of pediatric patients. Animal models provided meaningful insight in the causal relationship between abnormal mucosal immune activation and changes in gastrointestinal (GI) sensory-motor function. Likewise, the development of long-standing GI symptoms fulfilling the current criteria for functional GI disorders after infection gastroenteritis and in patients with IBD or celiac disease in remission further supports this hypothesis. Immune activation, its impact on gut sensory-motor function, and potential implications for symptom generation emerged in both children and adults with IBS. PURPOSE: The aim of this review is to summarize the main evidence on the presence of low-grade inflammation and immune activation in children with IBS, its possible role in symptom generation, and its potential implication for new therapeutic strategies.

Robotic surgery has been increasingly applied to Hirschsprung patients with encouraging results. We report the results of a 5 year unicentric experience. All consecutive HSCR patients older than 12 months who underwent a surgical procedure with robotic approach between September 2017 and August 2022 were prospectively included. We collected data regarding demographics, extent of aganglionosis, associated anomalies, indications to surgery, and a number of perioperative data such as surgical details, intraoperative and perioperative complications, length of surgery, length of hospital stay, and functional outcome. A total of 28 patients underwent 31 robotic procedures during the study period. Median age at surgery was 82 months. Eleven primary Totally Robotic Soave Pull-Through, 12 redoes, 5 innervative mapping, 2 redundant rectal pouch excision, and 1 Miles' procedures have been performed. Median console time was 145 min. No conversion to either laparoscopy nor to laparotomy was required. Median length of hospital stay was 6 days. Two patients experienced complications requiring reiterative surgery. One patient experienced mild postoperative enterocolitis. Normal continence was achieved by 70% of patients after a median of 16 months postoperatively (80% for primary pull-throughs, 55% for redoes). To conclude, robotic surgery for older HSCR patients proved to be feasible, safe, and effective. Patients with complex surgical requirements seem to benefit most from this promising approach. Provided the economic burden is addressed and solved, robotic surgery will represent an excellent alternative for the surgical treatment of HSCR patients.

BACKGROUND: Exclusive enteral nutrition (EEN) is the first choice to induce remission and promote mucosal healing in pediatric Crohn's disease (CD). However, full adherence to EEN treatment may be problematic for children with CD. METHODS: The goal of the current multicenter retrospective study was to define predictive factors of nonadherence to treatment and nonremission at the end of induction treatment. Those data together were analyzed with the ultimate goal of trying to define an individualized induction treatment for children with CD. RESULTS: Three hundred seventy-six children with CD from 14 IBD pediatric referral centers were enrolled in the study. The rate of EEN adherence was 89%. Colonic involvement and fecal calprotectinâ >600 µg/g at diagnosis were found to be associated with a reduced EEN adherence. Exclusive enteral nutrition administered for 8 weeks was effective for inducing clinical remission in 67% of the total cohort. Factors determining lower remission rates were ageâ >15 years and Pediatric Crohn's Disease Activity Index >50. CONCLUSION: Although EEN is extremely effective in promoting disease remission, several patients' related factors may adversely impact EEN adherence and response. Personalized treatments should be proposed that weigh benefits and risks based on the patient's disease location, phenotype, and disease activity and aim to promote a rapid control of inflammation to reduce long-term bowel damage.

To carry out effective and quick identification of SARS-CoV-2 from nasopharyngeal swabs and contain outbreaks, reliable and rapid tools are needed. Herein, we compared a rapid antigen test based on active microfluidic technology to an RT-qPCR assay in pediatric and young adult patients admitted to the Pediatric Emergency Unit of a Children's Hospital. Nasopharyngeal swabs collected from patients with suspected COVID-19 disease and from those without COVID-19 related symptoms, but requiring hospitalization, were performed with both antigen test and RT-qPCR assays. We included 375 patients with a median age of 5 years in the study, with an estimated overall prevalence of 7.2%. Overall, we observed a specificity of 97.4% (95% CI: 94.9-98.7) and a sensitivity of 66.6% (95% CI: 46.0-82.7) with a positive likelihood ratio (LR+) of 25.8 (95% CI: 12.8-51.8). In the subgroup of symptomatic patients, the specificity and the sensitivity were 95.2% (95% CI: 89.4-98.0) and 80.0% (95% CI: 44.2-96.5) respectively; LR+ was 16.6 (95% CI: 7.19-38.6). In the asymptomatic subset, the performance showed a specificity of 98.7% (95% CI: 95.8-99.7), a sensitivity of 58.8% (95% CI: 33.5-80.6), and an LR+ of 43.7 (95% CI: 13.3-144.0). Compared to RT-qPCR, the new microfluidic-based antigen test showed higher specificity (>95%) in the pediatric population, thus representing a suitable point-of-care testing (POCT) in a clinical setting with low prevalence of COVID-19.

Congenital adrenal hyperplasia (CAH) is a group of autosomal recessive disorders caused by enzyme deficiencies required for cortisol biosynthesis in the adrenal cortex. The majority of CAH are due to the deficiency of the 21-hydroxylase enzyme, while 3ß-hydroxysteroid dehydrogenase type 2 deficiency accounts for less than five percent of all CAH cases. We report two Moroccan twins from a spontaneous triplet pregnancy. The 46,XY newborn exhibited a disorder of sexual differentiation (DSD) with hypo virilization, while the 46,XX newborn had normal female external genitalia. In the first week of life, they showed hyponatremia and primary adrenal insufficiency with a slight 17OHP elevation and increased DHEAS and renin levels. The aCGH-SNP analysis disclosed a 8.36 Mb long contiguous stretch of homozygosity (LCSH) on chromosome 1p13.2-p11.2 including the candidate HSD3B2 gene, a LCSH of 7.3 Mb on 14q31.1-q32.11, and a 7 Mb duplication on 10q22.3-q23.2. Clinical exome sequencing revealed the biallelic c.969T > G (p.Asn323Lys) HSD3B2, likely pathogenic, variant in both of the affected twins. This case emphasizes the importance of a prompt molecular diagnosis performed through the combination of aCGH and clinical exome, both for establishment of correct therapy and for follow-up, as the newborns also carry a genomic rearrangement with possible clinical implications.

BACKGROUND: Urinary tract infections (UTIs) are a frequent disorder of childhood, mainly caused by Escherichia coli. The aim of this study was to evaluate the antimicrobial susceptibility trend in bacterial isolates in urine cultures in pediatric environment, analyzing data from our laboratory in a 6-year period. METHODS: A retrospective study was performed in AO SS. Antonio e Biagio e Cesare Arrigo (Pediatric Hospital) of Alessandria in Piedmont, North Ital. From 2015 to 2020, in a 6-year period, 1299 urinocultures were collected. Data collection was focused on demographic characteristics (age and sex) and laboratory findings (positive urocultures, antibiogram). RESULTS: Positive urocultures were 577, in which Escherichia coli represented most isolates (428, 74.2%). We found a statistically significant trend toward amoxiclavulanate resistance in the E. coli positive urinoculture comparing the period 2015-2018 vs. 2019-2020. CONCLUSIONS: Actual guidelines mostly recommend for amoxicillin-clavulanate prescription as first-line option for pediatric UTI management, this indication might be partially reconsidered. Our data underline the importance to conduct surveillance studies to determine local prevalence of antibiotic resistance to optimize therapeutic management.
