BACKGROUND: Duodenal ulcer (DU) causes various symptoms in children. The prevalence of Helicobacter pylori (Hp)-associated DU has been reducing in some regions, yet the updated trend in Taiwan is unknown. Risk factors of DU recurrence have not been comprehensively investigated in children. METHODS: This retrospective study included children diagnosed with DU to evaluate the demographics, symptoms, diagnostics, treatment, and outcomes. Specific populations (infant, surgery required) were sorted for subgroup analysis...

A 12-year-old boy was transferred to our pediatric department from a rural hospital for fever, cough, and vomiting associated with thrombocytopenia, non-immune hemolytic anemia, and acute kidney injury, leading to the diagnosis of hemolytic uremic syndrome (HUS). A nasopharyngeal swab and a lower respiratory sample detected Influenza A by polymerase chain reaction (PCR). The patient was treated with oseltamivir and intravenous fluids in addition to fresh frozen plasma (FFP). Enteropathogenic Escherichia coli (EPEC) was detected in a stool sample by PCR...

BACKGROUND: Helicobacter pylori infection is primarily acquired in childhood and can lead to peptic ulcer diseases and gastric cancer. The prevalence of H. pylori infection varies widely in different countries. The aim of this study was to explore the change of pediatric H. pylori seroprevalence in the past two decades and to investigate the risk factors for pediatric H. pylori seropositivity in southern Taiwan. MATERIALS AND METHODS: This study enrolled children aged 7-12 years in Tainan City in 2018 and compared the result with our previous data in 1998, 2005, and 2010...

AIMS: Nodular gastritis (NG) represents a frequently observed clinical presentation of Helicobacter pylori (H. pylori) infection in pediatric patients. This investigation aimed to explore the microbiota and histological features of the gastric mucosa in children with H. pylori colonized NG. MAIN METHODS: The current investigation examined a sample of 120 children who underwent gastroscopy due to symptoms of gastrointestinal distress, which showed that 64 were patients with H...

OBJECTIVE: To describe the clinical, endoscopic, histologic, and treatment outcomes of Helicobacter heilmannii (H. heilmannii) associated gastritis in children in the New England region of the United States. METHODS: Retrospective study of children (1-18 years) with H. heilmannii identified on gastric mucosal biopsies from two pediatric centers over a 21-year period, January 2000-December 2021. Cases were identified by querying pathology databases at each institution...

UNLABELLED: Helicobacter pylori infection is a common condition that, in the long term, is associated with the development of peptic ulcer disease and eventually gastric cancer, which could be prevented with timely treatment. Optimally, eradication success should be greater than 90%, but the recommended empirical treatments do not achieve these rates in real-life conditions. OBJECTIVE: To determine the success rate of first-line empirical eradication treatment against H...

We conducted this study to systematically review and assess the current clinical practice guidelines (CPGs) related to the diagnosis and treatment of Helicobacter pylori (H. pylori) infection. The aim was to evaluate the quality of these included CPGs and provide clinicians with a convenient and comprehensive reference for updating their own CPGs. We searched four databases to identify eligible CPGs focusing on H. pylori diagnosis and treatment recommendations. The results were presented using evidence mappings...

Helicobacter cinaedi is known to cause invasive infections in immunocompromised adults. Here we report the first case of H. cinaedi bacteremia in a child with nephrotic syndrome. The patient presented with a mild transient febrile illness that resolved spontaneously. We discuss the diagnostic challenges associated with this case and the microbiologic approach, including genomic analysis. Furthermore, we review the current case together with all previous pediatric cases (n = 6). Notably, all cases involved neonates or otherwise immunocompromised individuals and were characterized by severe disease with complicated infections (eg, meningitis, cholangitis and arthritis)...

Background and Objectives : Type 1 diabetes mellitus (T1DM) is a chronic and serious condition that is characterized by inadequate pancreatic-β-cells' insulin production. The connection between T1DM and Helicobacter pylori infection remains uncertain. This study aimed to conduct a systematic meta-analysis to examine the association between H. pylori infection, hemoglobin A1c levels, and the development of T1DM. Materials and Methods : The initial search identified 451 articles on the association between H...

Probiotics are live microorganisms that confer health benefits to the host when administered in adequate amounts. Although recommendations for probiotic use should be strain-specific, many systematic reviews, including recommendations from different societies, recommend probiotic use in general, providing no relevant information for healthcare professionals regarding which probiotic to recommend for which clinical indication, at what dose, and for how long. This narrative review aimed to present the available evidence on the use of probiotics in the prevention and treatment of common gastrointestinal diseases in children, considering the strain and dose used...

PURPOSE: We investigated the role of CD8+ T cells as host immune factors in pediatric patients with Helicobacter pylori gastritis. METHODS: Gastric mucosal tissue and blood samples were collected from 39 children, including 11 children with H. pylori infection and 28 children as controls. Anti-CD8 and anti-T-bet antibodies were used for immunohistochemistry of the gastric mucosa. For the cell surface and intracellular staining, peripheral blood mononuclear cells were stained with anti-IL7Rα, anti-CX3CR1, anti-CD8, anti-T-bet, and anti-IFN-γ antibodies...

PURPOSE: This study aimed to investigate the presence of autoantigens in the gastric juices of children. METHODS: Gastric juice and serum samples were obtained from 53 children <15 years of age who underwent gastric endoscopy. Among these, 8, 22, and 23 participants were in the age groups 0-5, 6-10, and 11-15 years, respectively. These samples were analyzed using two-dimensional electrophoresis (2-DE), immunoblot analysis, and matrix-assisted laser desorption ionization-time of-flight mass spectrometry...

BACKGROUND: Celiac disease (CD) is an immune-mediated enteropathy that has been associated with other immune-related gastrointestinal disorders, such as eosinophilic esophagitis (EoE) and lymphocytic gastritis (LG). To our knowledge, this is the first study in Saudi Arabia that has described such an association. AIM: To evaluate the prevalence of EoE and LG in children and adolescents with CD. METHODS: This was a retrospective cross-sectional study of all pediatric patients (aged 0-18 years) with CD following up at King Abdulaziz University Hospital, between January, 2014, and December, 2021...

Helicobacter pylori is a known cause of peptic ulcers, but it has not been reported to cause strictures in children. We present the case of a previously healthy 12-year-old boy with sudden onset of abdominal pain and vomiting, positive stool H. pylori antigen testing, and esophagogastroduodenoscopy revealing a gastroduodenal stricture causing gastric outlet obstruction. Because of medically refractory disease, he ultimately required laparoscopic truncal vagotomy with open pyloroplasty. This is an unusually severe presentation and may warrant H...

BACKGROUND: Helicobacter pylori (Hp) is a global public health concern, particularly among children. While the "detection and treatment" approach gains ground in adult patients, paediatricians have divergent opinions regarding the current clinical protocols for diagnosing and treating Hp infection. Some argue for its potential impact on children's growth, emphasizing the need for adequate attention. Additionally, there are uncertainties regarding the appropriate screening tests for children who require Hp testing or have functional dyspepsia...

For the diagnosis and post-treatment monitoring of H. pylori infection, non-invasive testing methodologies improve patient comfort, particularly for children. Previously, only the BreathTek UBT had FDA approval for use in pediatric patients and required an adjustment calculation based on age, height, and weight of the patient. The purpose of this study was to evaluate the performance of the PyloPlus UBT assay in a pediatric population.

Pediatric Helicobacter pylori infection represents a small proportion of disease that is otherwise decreasing in the developed world. Typical presentations have been well-described in the literature. We report a 15-year-old male who presented with jaundice, anemia, dark urine, and poorly characterized abdominal pain and was found to have obstructive jaundice secondary to a duodenal ulcer resulting from H. pylori infection. Obstructive jaundice is a seldom reported complication of duodenal ulcer, particularly in children...

BACKGROUND: Helicobacter pylori antibiotic resistance has increased worldwide and affects the effectiveness of current therapies. The recommended first-line empiric treatment should be tailored to the local clarithromycin resistance rate. This study aimed to determine the pediatric patient profile and rate of clarithromycin resistance for patients diagnosed with Helicobacter pylori by gastric biopsy. METHODS: We studied 84 positive gastric samples for Helicobacter pylori ...

Gastrocolic fistulas are very rare in children and their association with Helicobacter pylori is poorly described. We present the case of a 10-year-old boy with a history of chronic abdominal pain, diarrhea, halitosis, and growth delay diagnosed with H. pylori-associated gastritis and gastrocolic fistula. The boy recovered with resection surgery and antibiotic therapy for eradication of the pathogen. This is the first description of a gastrocolic fistula in pediatrics related to H. pylori.
