Proton pump inhibitors (PPIs) are amongst the most commonly prescribed drugs in infants and children with the last decades witnessing a dramatic rise in their utilization. Although PPIs are clearly effective when used appropriately and have been regarded as safe drugs, there is growing evidence regarding their potential adverse effects. Although, largely based on adult data it is clear that many of these are also relevant to pediatrics. PPI use potentially affects gastrointestinal microbiota composition and function, decreases defence against pathogens resulting in increased risk for infections, interferes with absorption of minerals and vitamins leading to specific deficiencies and increased risk for bone fractures as well as interferes with protein digestion resulting in increased risk of sensitization to allergens and development of allergic diseases and eosinophilic esophagitis. An association with gastric, liver and pancreatic cancer has also been inferred from adult data but is tenuous and causation is not proven. Overall, evidence for these adverse events is patchy and not always compelling. Overall, the use of PPIs, for selected indications with a good evidence base, has significant potential benefit but carries more caution in infants and children. Pediatricians should be aware of the concerns regarding the potential adverse events associated with their use.

Cholestasis is caused by a wide variety of etiologies, often genetic in origin. Broad overlap in clinical presentations, particularly in newborns, renders prioritizing diagnostic investigations challenging. In this setting, a timely, comprehensive assessment using a multigene panel by a clinical diagnostic laboratory would likely prove useful. We summarize initial findings from a testing program designed to discover genetic causes of cholestasis.

Dubin-Johnson syndrome (DJS) is an autosomal recessive disorder in which multidrug-resistance-associated protein 2 (MRP2) deficiency causes an excretion disorder of conjugated bilirubin from hepatocytes into bile canaliculi. Its clinical presentation as neonatal cholestasis (NC) is rare but represents an important differential diagnosis. We aimed to define DJS-specific characteristics in NC, in particular in contrast to biliary atresia (BA) patients, and to highlight diagnostic tools that can help to avoid invasive diagnostic tests.

Current practice during pediatric colonoscopy is to obtain random colonic biopsies, even from normal appearing tissue. The majority of literature published on colonic biopsy practice analyzes adults; however, limited data examines the pediatric population. The lack of standardization regarding tissue sampling during pediatric colonoscopy reinforces the necessity to study this question objectively. The aim of the present study was to assess the value of obtaining mucosal biopsies from grossly normal colonic tissue.

While the algorithm to diagnose celiac disease (CD) in children with elevated anti-transglutaminase IgA (TGA-IgA) titers (>10 times upper limit of normal, ULN) is well defined, the management of children with low TGA-IgA values represents a clinical challenge. We aimed to identify the diagnostic value of persistently low positive TGA-IgA titers in predicting CD in children.

A case of low-?-glutamyltranspetidase cholestasis associated with ubiquitin-specific peptidase 53 (USP53) gene mutation in a Brazilian child is described. Transient jaundice and hypocholia started at the age of 10 days. Liver enzymes, total bilirubin, and total bile acids were elevated at presentation. During follow-up, he developed cholelithiasis treated with cholecystectomy, and an intracranial hemorrhage resolved with full recovery. At last, evaluation at the age of 18 months, he was not jaundiced and had normal liver tests, but experienced from moderate pruritus despite treatment with rifampicin and ursodeoxycholic acid. A genetic study revealed novel homozygous mutations c.1687_1688delinsC p.Ser563Profs?25 in the USP53 gene. His parents carried the same heterozygous mutation in the USP53 gene.

Infection with severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) can lead to coronavirus-induced disease 2019 (COVID-19). The gastrointestinal (GI) tract is now an appreciated portal of infection. SARS-CoV-2 enters host cells via angiotensin-converting enzyme-2 (ACE2) and the serine protease TMPRSS2. Eosinophilic gastrointestinal disorders (EGIDs) are inflammatory conditions caused by chronic type 2 (T2) inflammation. the effects of the T2 atopic inflammatory milieu on SARS-COV-2 viral entry gene expression in the GI tract is poorly understood. We analyzed tissue ACE2 and TMPRSS2 gene expression in pediatric eosinophilic esophagitis (EoE), eosinophilic gastritis (EG), and in normal adult esophagi using publicly available RNA-sequencing datasets. Similar to findings evaluating the airway, there was no difference in tissue ACE2/TMPRSS2 expression in EoE or EG when compared with control non-EoE/EG esophagus/stomach. ACE2 gene expression was significantly lower in esophagi from children with or without EoE and from adults with EoE as compared with normal adult esophagi. Type 2 immunity and pediatric age could be protective for infection by SARS-CoV-2 in the gastrointestinal tract because of decreased expression of ACE2.

The incidence of Clostridioides difficile infection (CDI) has been increasing in the United States. About 10–20% recur after initial treatment, with increasing recurrence following subsequent treatment courses. This sequence can lead to recurrent CDI (rCDI), refractory to conventional therapeutics resulting in the most common indication for fecal microbiota transplantation (FMT). FMT is the most effective microbial therapeutic to date and can cure rCDI in 80–90% of cases. There is growing concern, however, for pathogen transmission through FMT, underscoring the importance of careful recipient selection. In adults referred for FMT with a tentative diagnosis of rCDI, alternative diagnoses were recognized in 25% of patients, but such observation in children is lacking. In this single-center retrospective study, alternative diagnoses (eg, constipation/overflow diarrhea, inflammatory bowel disease) were found in 13 (22.4%) of 58 children who were referred for FMT evaluation for rCDI. Of the patients who were diagnosed with rCDI, 16 (27.6%) did not require FMT.

Since the approval of the first proton pump inhibitor (PPI) in 1989, our knowledge regarding this class of medications has further developed. An increasing amount of data now supports the association between cytochrome P450 2C19 (CYP2C19) phenotype and PPI safety and efficacy. This includes pediatric studies, such as those published here and in other pediatric journals within the past year. Moreover, the most recent pediatric Helicobacter pylori guidelines stated that using the PPIs that are less dependent on CYP2C19 for inactivation may be preferred for H pylori eradication among populations that are more likely to have rapid clearance of CYP2C19-metabolized PPIs. Conversely, pantoprazole package insert recommends a dose reduction in known pediatric CYP2C19 poor metabolizers (PMs), citing a 6-fold increase in serum concentrations compared with normal metabolizers (NMs). The purpose of this communication is to introduce a recently published Clinical Pharmacogenetics Implementation Consortium (CPIC) guideline for CYP2C19 and PPI dosing.

The information blocking (IB) prohibition component of the 21st Century CURES Act (21CCA) comes into effect April 5, 2021, which gives patients and their families near-instant access to almost all clinical notes, lab results, and health data. Exceptions to IB prohibition include risk of harm and patient privacy, but violations can be punished by a fine of up to $1,000,000.00. A committee of pediatric gastroenterologists reviewed the 21CCA regulation and compared local practice policies. Pediatric practitioners need to understand how age will affect local information release policies and to know which note types are released, paying special consideration to trainee notes and confidential information. Extraneous detail should be removed from notes, emotional labeling be avoided, and objective statements be made when referring to the care of other providers. Awareness of the 21CCA provides pediatric gastroenterologists with the opportunity to adapt their medical documentation practices to accommodate the new law.

Venous thromboembolism (VTE) is a known complication in children with inflammatory bowel disease (IBD). Despite awareness of the increased thrombosis risk in this population, prophylaxis is not standardly used and there is limited published guidance for thrombosis prevention. To better appreciate the impact of thrombosis in this population, we compared children with IBD who did or did not have a VTE, using the Pediatric Health Information System inpatient database from 2009 to 2017. In hospitalized children with IBD, VTE was associated with longer median hospital stays (11 vs 5 days), need for intensive care unit admission (30.2% vs 4.8%), higher median adjusted costs ($32.8k vs $12.3k) and hospital charges ($96.6k vs $36k), and in-hospital death (1.5% vs 0.2%) (P < 0.001 in all comparisons). These findings highlight the need to determine and implement appropriate strategies to reduce VTE rates in children with IBD, given its association with high morbidity, mortality, and cost.

Transgender and gender nonconforming (TGNC) individuals have a different gender identity than the sex they were assigned at birth. Despite an increase in provider awareness of TGNC health over the past decade, no original research or societal guidelines exist on TGNC patients with inflammatory bowel disease (IBD). We review TGNC IBD cases in the University of California, San Francisco (UCSF) Pediatric IBD Program and in the literature. We then provide some recommendations for the provision of high-quality care to the TGNC IBD population, divided into 3 categories: medications, anatomy, and mental health.

Childhood obesity has high societal and economic impact but current treatment approaches are sub-optimal. In the last decade, important studies have been conducted aiming to identify strategies to prevent obesity during critical periods of life. Updated recommendations for childhood obesity prevention are needed. We present data from systematic reviews and meta- analysis, randomised controlled trials (RCTs) and large observational studies, published from 2011 onwards that consider the possible role of the following factors in obesity development: breast-feeding; macronutrient composition and method of complementary feeding; parenting style; dietary patterns; sugar-sweetened beverage consumption; eating behaviour (eg, skipping breakfast, family dinners. etc); meal frequency and composition (fast foods, snacking), portion size; dietary modulators of gut microbiota (including pre-, pro-, and synbiotics); physical activity and sedentary behaviour. We used the Medline database and the Cochrane Library to search for relevant publications. Important research gaps were also identified. This position paper provides recommendations on dietary factors, food habits, and lifestyle to prevent childhood obesity development, based on the available literature and expert opinion. Clinical research and high-quality trials are urgently needed to resolve numerous areas of uncertainty.
