A randomised controlled clinical study of standard triple therapy, bismuth-based quadruple therapy and sequential therapy for Helicobacter pylori infection in children. BMC Pediatr 2024; 24:543. [PMID: 39180014 PMCID: PMC11342529 DOI: 10.1186/s12887-024-05020-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/30/2024] [Accepted: 08/19/2024] [Indexed: 08/26/2024] Open
Abstract
BACKGROUND AND AIM Bismuth and non-bismuth quadruple therapy are the guideline-recommended first-line therapy in children with Helicobacter pylori infection in areas with high antibiotic resistance. However, their efficacy in children is uncertain and there are few well-designed studies. Here, we evaluated the eradication rates of standard triple therapy, bismuth-based quadruple therapy and sequential therapy in children with H. pylori infection. METHODS A randomised controlled trial was conducted in children infected with H. pylori in West China Second Hospital. They were randomly assigned to 14-day standard triple therapy (omeprazole + amoxicillin + clarithromycin), 14-day bismuth quadruple therapy (bismuth + omeprazole + amoxicillin + clarithromycin) and 10-day sequential therapy (omeprazole + amoxicillin for 5 days followed by omeprazole + clarithromycin + metronidazole for 5 days). The eradication rate was assessed by a 13C-urea breath test 4 to 6 weeks after therapy completion. Symptom improvement and adverse events were compared among the groups. RESULTS In total, 132 patients were enrolled. The eradication rates of 14-day standard triple therapy, 14-day bismuth quadruple therapy and 10-day sequential therapy were 70.0%, 78.9% and 50.0% in per-protocol analysis and 63.6%, 68.2% and 43.2% in intention-to-treat analysis, respectively. Symptom improvement and adverse drug event rates were similar in the three groups. CONCLUSION The three therapeutic regimens evaluated in this study are equally not recommendable for H. pylori infection treatment due to unsatisfactory eradication rates. The high prevalence of clarithromycin resistance makes the use of clarithromycin-based quadruple therapy not advisable, even in combination with amoxicillin and bismuth salts.

Abstract
In the context of epidemiology, host response, disease presentation, diagnosis, and treatment management, the manifestation of Helicobacter pylori (H. pylori) infection diverges between children and adults. H. pylori infection stands out as one of the most prevalent bacterial infections globally, and its prevalence in both children and adults is decreasing in many developing countries but some still struggle with a high prevalence of pediatric H. pylori infection and its consequences. The majority of infected children are asymptomatic and pediatric studies do not support the involvement of H. pylori in functional disorders such as recurrent abdominal pain. The pathophysiology of H. pylori infection relies on complex bacterial virulence mechanisms and their interaction with the host immune system and environmental factors. This interaction gives rise to diverse gastritis phenotypes, which subsequently influence the potential development of various gastroduodenal pathologies. In clinical settings, the diagnosis of this infection in childhood requires an upper gastrointestinal endoscopic exam with mucosal biopsy samples for histology and culture, or Polymerase Chain Reaction (PCR) at the very least. When warranted, eradication treatment should be given when good compliance is expected, and there should be systematic use of a treatment adapted to the antimicrobial susceptibility profile. To combat the burgeoning threat of multidrug resistance, vigilant surveillance of resistance patterns and strategic antibiotic management are paramount.

Abstract
INTRODUCTION The resistance to antibiotics of Helicobacter pylori (H. pylori) is the main factor that affects current therapeutic treatments. The main objective of this study is to describe the pattern of antibiotic resistances in children with an infection due to H. pylori. PATIENTS AND METHODS An observational, retrospective study was conducted from 2014 to 2019, which included patients between 5 and 17 years old, on whom a gastroscopy, with a gastric biopsy culture positive for H. pylori, and an antibiotic sensitivity study was performed. The antibiotic sensitivity studies were performed using an epsilometer (E-test). The cut-off points to define the resistances were those proposed by the European Committee on Antimicrobial Susceptibility Testing - EUCAST. The eradication study was performed using the 13C-urea breath test or the H. pylori monoclonal test in faeces 6-8 weeks after finalising the treatment. RESULTS The study included 80 patients (63.8% females), with a mean age of 11.9 years (SD ± 2.7 DS). Over one-third (38.8%) of the patients had received previous treatment for H. pylori. In the endoscopy, peptic ulcer lesions were observed in 10% of patients. More than two-thirds (67.5%) had resistance to at least one drug. 16.3% presented double resistance. The primary resistances were: clarithromycin, 44.9%, metronidazole 16.3%, levofloxacine 7.9%, and amoxicillin 2%. Patients that received treatment according to the new ESPGHAN 2017 guidelines had significantly higher eradication rates compared to those that received treatment according to previous guidelines (80% vs. 55.8%, P = 0.04). CONCLUSIONS The high rate of H. pylori resistances, and as a result, the low eradication rates, are still a very important cause for concern. The first line treatment, when this is indicated must be given following the antibiotic sensitivity studies, and in the cases where these cannot be done or are not available, at least in accordance with the regional resistance rates. The correct application of the new guidelines significantly improves the eradication rate.

Abstract
The Indian Society of Gastroenterology (ISG) felt the need to organize a consensus on Helicobacter pylori (H. pylori) infection and to update the current management of H. pylori infection; hence, ISG constituted the ISG's Task Force on Helicobacter pylori. The Task Force on H. pylori undertook an exercise to produce consensus statements on H. pylori infection. Twenty-five experts from different parts of India, including gastroenterologists, pathologists, surgeons, epidemiologists, pediatricians, and microbiologists participated in the meeting. The participants were allocated to one of following sections for the meeting: Epidemiology of H. pylori infection in India and H. pylori associated conditions; diagnosis; treatment and retreatment; H. pylori and gastric cancer, and H. pylori prevention/public health. Each group reviewed all published literature on H. pylori infection with special reference to the Indian scenario and prepared appropriate statements on different aspects for voting and consensus development. This consensus, which was produced through a modified Delphi process including two rounds of face-to-face meetings, reflects our current understanding and recommendations for the diagnosis and management of H. pylori infection. These consensus should serve as a reference for not only guiding treatment of H. pylori infection but also to guide future research on the subject.

Abstract
The Japan Pediatric Helicobacter pylori Study Group published the first guidelines on childhood H. pylori infection in 1997. They were later revised by the Japanese Society for Pediatric Gastroenterology, Hepatology and Nutrition (JSPGHAN). The H. pylori eradication rates, when employing triple therapy with amoxicillin and clarithromycin, currently recommended as the first-line therapy of H. pylori infection in Japan, have substantially decreased, creating an important clinical problem worldwide. In Japanese adults, the "test-and-treat" strategy for H. pylori infection is under consideration as an approach for gastric cancer prevention. However, the combined North American and European pediatric guidelines have rejected such a strategy for asymptomatic children. As risk for gastric cancer development is high in Japan, determining whether the "test-and-treat" strategy can be recommended in children has become an urgent matter. Accordingly, the JSPGHAN has produced a second revision of the H. pylori guidelines, which includes discussion about the issues mentioned above. They consist of 19 clinical questions and 34 statements. An H. pylori culture from gastric biopsies is recommended, not only as a diagnostic test for active infection but for antimicrobial susceptibility testing to optimize eradication therapy. Based upon antimicrobial susceptibility testing of H. pylori strains (especially involving clarithromycin), an eradication regimen including use of the antibiotics to which H. pylori is susceptible is recommended as the first-line therapy against H. pylori-associated diseases. The guidelines recommend against a "test-and-treat" strategy for H. pylori infection for asymptomatic children to protect against the development of gastric cancer because there has been no evidence supporting this strategy.

Abstract
BACKGROUND Previously, we conducted an epidemiological study screening for Helicobacter pylori antibody positivity among Japanese junior high school students. In this study, we updated the epidemiological data and assessed the clinical features of H pylori antibody-positive junior high school students. MATERIALS AND METHODS We assessed H pylori antibody-positive subjects who were identified between 2012 and 2015 at four junior high schools in Nagano Prefecture, Japan. H pylori infection was confirmed by urea breath test (UBT) or endoscopic examination. Endoscopy was performed after obtaining consent from the subject and their guardians. Eradication therapy consisted of triple therapy with proton pump inhibitor (PPI), amoxicillin (AMPC), and clarithromycin (CAM) or metronidazole (MNZ) for seven days. Eradication of H pylori was confirmed by UBT. We reviewed subjects' characteristics, endoscopic findings, histological findings, eradication regimes, outcomes, and adverse effects. RESULTS The overall prevalence of H pylori antibody positivity was 3.2% (42/1298). We assessed thirteen H pylori antibody-positive subjects. Eight subjects had a family history of H pylori infection. Six subjects had abdominal pain, and two subjects had iron deficiency anemia (IDA). Twelve subjects underwent endoscopy; one subject had duodenal ulcer, eleven subjects had antral nodular gastritis, and six subjects showed grade 2 closed type atrophic border according to the Kimura-Takemoto classification. All subjects received eradication therapy; CAM was used in five subjects with CAM susceptibility as well as in three subjects with unknown information on CAM susceptibility, and MNZ was used in five subjects with CAM resistance. Eradication was successful in twelve subjects (one unconfirmed). There were three mild adverse effects (abdominal pain or diarrhea). CONCLUSIONS Helicobacter pylori test for junior high school students represents an opportunity to diagnose the peptic ulcer, iron deficiency anemia, and gastric atrophy.

Abstract
BACKGROUND In adults, Helicobacter pylori is aetiologically associated with peptic ulcer disease and gastric cancer. However, the relationship between this bacteria and gastro-intestinal symptoms in children is less clear. AIMS To review the recent literature on H. pylori in children and to outline the approach to diagnosis and management. METHODS The English language literature was searched for articles on H. pylori in children. Special attention was paid to prevalence, diagnosis and management pertinent to low- and middle-income countries (LMIC). RESULTS Although the prevalence of H. pylori is 60-80% in LMIC, only 5% of infected children develop peptic ulcer disease. The virulence of the organism determines the outcome. There is a suggestion that H. pylori causes iron deficiency anaemia, growth retardation and idiopathic thrombocytopenic purpura, but the evidence is not sufficiently strong to justify screening. There is no evidence to suggest a link between H. pylori infection and recurrent abdominal pain. Endoscopy (with invasive tests) is the preferred method of investigation as the primary goal is to determine the underlying cause of the symptoms. Children with H. pylori-related diseases should be treated with a standard triple-drug regimen consisting of a protein pump inhibitor and two antibiotics for 10-14 days. All treated patients should be monitored for eradication with non-invasive tests such as the urea (13-C) breath test or stool antigen tests. CONCLUSIONS Although H. pylori infection is common in LMIC, most children are asymptomatic. There is no association between H. pylori and recurrent abdominal pain. Invasive tests are preferred for diagnosis and a triple-drug regimen is the treatment of choice.

Abstract
Helicobacter pylori infection is acquired mainly in childhood and remains an essential cause of peptic ulcer disease and gastric cancer. This article provides commentary on the last ESPGHAN/NASPGHAN guidelines and on publications made after the consensus conference of 2015. The majority of infected children are asymptomatic and pediatric studies do not support a role for H. pylori in functional disorders such as recurrent abdominal pain. The role of H. pylori infection in failure to thrive, children's growth, type I diabetes mellitus (T1DM), and celiac disease remains controversial. The diagnosis of infection should be based on upper-digestive endoscopy with biopsy-based methods. Eradication control after treatment should be based on validated non-invasive tests. Nodular gastritis is the main endoscopic finding of childhood H. pylori infection, but gastroduodenal erosions/ulcers are seen in some children, especially after 10 years of age. When indicated, eradication treatment should be given when good compliance is expected and based on the antimicrobial susceptibility profile.

Abstract
INTRODUCTION Chronic abdominal pain (CAP) is one of the most common indications of esophagogastroduodenoscopy (EGD) in the pediatric population. However, there is not enough information about the diagnostic yield of EGD in children with CAP. We aimed to evaluate the diagnostic yield of EGD in children with CAP in the Eastern Black Sea region of Turkey. MATERIAL AND METHODS The study included children (n = 372) who underwent EGD for the primary indication of chronic abdominal pain during an 18-month period. We collected data on demographic features (age, sex), clinical characteristics (alarm symptoms), and EGD results for each patient. RESULTS Patients' mean age was 13 years (range: 4-17 years; mean ± SD: 12.65 ±3.39 years), and the majority were female (n = 234, 62.9%). Endoscopy was diagnostic in 209 patients (56.2%; 95% CI: 30.35-40.05%). The most common diagnosis was Helicobacter pylori gastritis (35.2%) followed by reflux esophagitis. Significantly greater diagnostic yield of EGD was determined in patients with alarm symptoms (65.1%) compared to those without (45.2%) (OR = 2.26, 95% CI: 1.49-3.44, p = 0.001). CONCLUSIONS We determined a high diagnostic yield of EGD in children with CAP. Although the diagnostic yield of EGD in the assessment of CAP was found to be higher in the presence of alarm symptoms, a significant number of children without alarm symptoms were also found to have gastrointestinal system pathology diagnosed by EGD.

The Placebo Response in Pediatric Abdominal Pain-Related Functional Gastrointestinal Disorders: A Systematic Review and Meta-Analysis. J Pediatr 2017; 182:155-163.e7. [PMID: 28081889 DOI: 10.1016/j.jpeds.2016.12.022] [Citation(s) in RCA: 35] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/02/2016] [Revised: 11/04/2016] [Accepted: 12/06/2016] [Indexed: 12/19/2022]
Abstract
OBJECTIVE To investigate the magnitude and determinants of the placebo response in studies with pediatric abdominal pain-related functional gastrointestinal disorders. STUDY DESIGN The Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE, and CINAHL were searched for systematic reviews and randomized placebo-controlled trials concerning children 4-18 years of age with an abdominal pain-related functional gastrointestinal disorder. The primary outcome was the pooled proportion of subjects assigned to placebo with improvement as defined by the authors. The effect of trial characteristics on the magnitude of the placebo response was investigated using univariate meta-regression analysis. RESULTS Twenty-one trials were identified. The pooled proportion of subjects with improvement was 41% (95% CI, 34%-49%; 17 studies) and with no pain was 17% (95% CI, 8%-32%; 7 studies). The pooled standardized mean difference on the Faces Pain Scales compared with baseline was -0.73 (95% CI, -1.04 to -0.42; 8 studies). There was significant heterogeneity across studies with respect to both outcomes. Lower dosing frequency (P = .04), positive study (P = .03), longer duration of treatment (P < .001), and higher placebo dropout (P < .001) were associated with higher report of no pain. Response on Faces Pain Scales was greater in studies conducted in the Middle East (P = .002), in studies that did not report the randomization schedule (P = .02), and in studies with a higher percentage of females (P = .04). CONCLUSIONS Approximately 41% of children with abdominal pain-related functional gastrointestinal disorders improve on placebo. Several trial characteristics are correlated significantly with the proportion of patients with no pain on placebo and with the magnitude of the placebo response on Faces Pain Scales. These data could be valuable for the design of future studies.

Abstract
Policy analysis shows that H. pylori test and treat strategies targeting adults at moderate to high risk of H. pylori-induced disease is likely to be cost-effective for preventing digestive diseases responsible for a large global disease burden. Little is known, however, about health benefits to children from eliminating this infection. We conducted a systematic review of the evidence regarding health benefits to children from treatment to eliminate H. pylori infection. We systematically searched Ovid MEDLINE for pertinent review articles published through 2012. We excluded reviews focused on treatment efficacy and scrutinized reference lists of selected reviews to identify additional eligible reviews. Fifteen reviews met specified inclusion criteria. Overall, they show that few reported studies investigating pediatric health effects of treatment for H. pylori infection were well designed with adequate statistical power. Thus, there is insufficient evidence for drawing conclusions about health benefits to children from treatment to eliminate H. pylori infection.

Abstract
OBJECTIVE As the clinical implications of Helicobacter pylori infection in children and adolescents continue to evolve, ESPGHAN and NASPGHAN jointly renewed clinical guidelines using a standardized evidence-based approach to develop updated recommendations for children and adolescents in North America and Europe. METHODS An international panel of 11 pediatric gastroenterologists, 2 epidemiologists, 1 microbiologist, and 1 pathologist was selected by societies that developed evidence-based guidelines based on the Delphi process with anonymous voting in a final face-to-face meeting. A systematic literature search was performed on 8 databases of relevance including publications from January 2000 to December 2009. After excluding nonrelevant publications, tables of evidence were constructed for different focus areas according to the Oxford classification. Statements and recommendations were formulated in the following areas: whom to test, how to test, whom to treat, and how to treat. Grades of evidence were assigned to each recommendation based on the GRADE system. RESULTS A total of 2290 publications were identified, from which 738 were finally reviewed. A total of 21 recommendations were generated, and an algorithm was proposed by the joint committee providing evidence-based guidelines on the diagnostic workup and treatment of children with H pylori infection. CONCLUSIONS These clinical practice guidelines represent updated, best-available evidence and are meant for children and adolescents living in Europe and North America, but they may not apply to those living on other continents, particularly in developing countries with a high H pylori infection rate and limited health care resources.

Abstract
OBJECTIVE To evaluate the efficacy of triple eradication therapy versus symptomatic therapy in children with Helicobacter pylori-associated chronic active gastritis (H pylori-ACAG). STUDY DESIGN Symptomatic patients with H pylori-ACAG (n=31) were randomly assigned into two groups: (1) patients infected with H pylori who were treated with triple eradication therapy (n = 16); and (2) patients infected with H pylori who were treated with symptomatic therapy (n=15). RESULTS After 1 year of follow-up, macroscopic appearance was significantly different in group B (P=.023), and chronic inflammation, H Pylori density, and activity were significantly higher in group B than in group A (P=.022, .007, and .002, respectively); however, we did not find a significant difference in the symptoms comparing both groups (P=.287). After 1 year of follow-up, we observed the persistence of the H pylori infection in all children who had not received eradication treatment. CONCLUSIONS There is no correlation between eradication of H pylori infection and improvement of dyspeptic symptoms. Self-eradication does not occur within 1 year of follow-up. A trend toward a higher rate of chronic inflammation in noneradicated children at 1 year limited the time of our study.

Abstract
OBJECTIVE To study extra- gastric manifestations of H. pylori infection among children in Egypt. METHODS This case-control study in which thirty [corrected] H pylori positive children were compared to thirty [corrected] H pylori negative children was conducted. Full history taking, clinical examination, CBC, serum iron, serum ferritin in addition to H pylori antibody testing were performed. RESULTS Mean hemoglobin, MCV, MCH, serum iron and serum ferritin were all less in seropositive patients but these were statistically non significant. Iron deficiency (ID) was defined as serum ferritin less than 12 ng/ml; and Iron deficiency anemia (IDA) as hemoglobin less than 11 g/dL in addition to ID. Seropositive patients showed increased frequency of ID and IDA and this was statistically significant (0.003 & 0.000 respectively). There was no statistically significant difference as regards the platelet counts of the two groups or the presence of skin disorders or the gender. CONCLUSIONS There is increased incidence of ID and IDA among H pylori positive children. This needs to be confirmed by larger therapeutic randomized controlled trials. The hematological response to eradication therapy needs to be further studied.

Abstract
Although evidence is emerging that the prevalence of Helicobacter pylori (H. pylori) is declining in all age groups, the understanding of its disease spectrum continues to evolve. If untreated, H. pylori infection is lifelong. Although H. pylori typically colonizes the human stomach for many decades without adverse consequences, children infected with H. pylori can manifest gastrointestinal diseases. Controversy persists regarding testing (and treating) for H. pylori infection in children with recurrent abdominal pain, chronic idiopathic thrombocytopenia, and poor growth. There is evidence of the role of H. pylori in childhood iron deficiency anemia, but the results are not conclusive. The possibility of an inverse relationship between H. pylori and gastroesophageal reflux disease, as well as childhood asthma, remains a controversial question. A better understanding of the H. pylori disease spectrum in childhood should lead to clearer recommendations about testing for and treating H. pylori infection in children who are more likely to develop clinical sequelae.

Abstract
BACKGROUND AND AIM Pain-predominant-functional gastrointestinal disorders (PP-FGIDs) are common. The diagnosis is clinical and there are no biological markers to characterize these conditions. Despite limited evidence, investigations are commonly performed. The aim of the study was to investigate diagnostic practices, yield, and costs in children with PP-FGIDs. PATIENTS AND METHODS Charts of all of the children older than 4 years diagnosed as having abdominal pain were reviewed. Results and costs of diagnostic investigations were analyzed. RESULTS Of 243 children with abdominal pain, 122 (50.2%) had PP-FGIDs (79 girls, mean age 12.7 years). All of the children underwent diagnostic work-up. Complete blood cell count was done in 91.8% of patients. None had elevated white blood cells, platelets, and low albumin. Six had either elevated erythrocyte sedimentation rate or C-reactive protein, but none had elevation of both; 4 of these 6 cases underwent endoscopies with normal results in 3 cases; Helicobacter pylori was found in 1 case. One child had elevated tissue transglutaminase 1 only antibodies with normal endoscopy. Amylase, lipase, direct bilirubin, stool cultures, and ova or parasites were always normal. One child had intermittent elevation of aspartate aminotransferase and alanine transaminase. There were no significant abnormalities in urinalysis or electrolytes. Abdominal x-rays were done in 38.5%, showing only retained stools in 13% of these patients. Abdominal ultrasound and computed tomography scan were done in 23.7% and 9% of cases, respectively, but were of no clinical value; 33.6% patients had esophagogastroduodenoscopy (9.7% abnormal: Helicobacter pylori, chemical gastritis, esophagitis) and 17.2% had colonoscopy (9.5% abnormal: rare fork crypts, lymphoid hyperplasia). Total costs: $744,726. Average cost per patient: $6104.30. CONCLUSIONS In children with PP-FGIDs, investigations are common, costs are substantial, and yield is minimal.

Abstract
Helicobacter pylori is one of the most common infections found in humans. It was first identified in 1982 and by 1989 had been associated with gastric inflammation and ulcers in adults and children. During the 1990's evidence emerged of its etiologic role in stomach cancers in adults. That the infection is common and may have serious consequences, has led to an avalanche of research during the last twenty years. During this time, there have been many studies on children which have sought an effective and safe treatment to eradicate the infection, but as yet, no therapy regimen has been found which is always effective and safe. This article provides information, from a pediatric point of view, on the major developments in the therapeutics and therapy of H. pylori infection. It examines first-line treatment regimens, evaluates the efficacy of the main drugs used in the management of (primary) H. pylori infection in children, assesses the potential for the use of probiotics and sequential therapy, examines therapeutic options after failure of initial treatment, and discusses factors affecting eradication rate, including antibiotic resistance, adherence to therapy, and bacterial factors.

Abstract
BACKGROUND Abdominal pain is the most common indication for oesophagogastroduodenoscopy (OGD) in children. However, existing studies examining the diagnostic outcomes of OGD in children with abdominal pain are limited. AIM To examine the diagnostic yield of OGD with biopsy in the evaluation of abdominal pain and to describe the endoscopic and histological findings in patients undergoing OGD for abdominal pain of unclear aetiology. METHODS We performed a retrospective cross-sectional cohort study in children under 18 years of age who had OGD for the primary indication of abdominal pain, at Texas Children's Hospital and Children's Hospital of The King's Daughters from 1 January 2002 to 30 June 2005. RESULTS Overall, OGD was diagnostic in 454 (38.1%) of the 1191 procedures, including reflux oesophagitis (23%, n = 271), Helicobacter pylori infections (5%, n = 55), peptic ulcers (3%, n = 32), eosinophilic oesophagitis (2%, n = 25), celiac disease (1%, n = 9) and Crohn's disease (0.5%, n = 7). Male gender, older age, elevated C-reactive protein and vomiting were associated with increased diagnostic yield. CONCLUSIONS Our findings suggest that OGD is valuable for the evaluation of chronic abdominal pain in children, with a diagnostic yield of 38%. The majority of alarm symptoms and routine laboratory tests are not significantly associated with diagnostic yield.

Abstract
AIM To investigate the link between H.pylori infection and dyspepsia in children, and association with reflux oesophagitis. PATIENTS AND METHODS H.pylori status was detected by rapid urease test and/or culture in 130 consecutive symptomatic children coming for upper gastrointestinal endoscopy: 40 - aged 8-12 years (55% boys); 90 - aged 13-18 years (21% boys). Endoscopic findings were analyzed. H.pylori prevalence in the age group 8-12 years was compared to the prevalence among 55 asymptomatic children, aged 7-12 years (13C-urea breath test). STATISTICAL ANALYSIS chi(2) test, Fisher's test, and logistic regression analysis. RESULTS The prevalence of H.pylori infection among patients with gastrointestinal symptoms was 54%. It was significantly higher among patients with reflux oesophagitis compared to patients with hyperaemic gastropathy: OR = 5.5; p = 0.03, 95% CI: 1.15-26.3. In logistic regression analysis, no significant difference between the prevalence of H.pylori infection between asymptomatic and symptomatic children could be demonstrated (OR = 1.8; 95% CI: 0.62-5.14). CONCLUSIONS The prevalence of H.pylori was significantly higher among patients with reflux oesophagitis compared to patients with hyperaemic gastropathy alone. Adjusting for age the prevalence of H.pylori infection was not higher among symptomatic children compared to asymptomatic children of the same age.

Abstract
BACKGROUND Several meta-analyses assessing the efficacy of anti-Helicobacter pylori treatment in adults have been published but a comparable meta-analysis in children is lacking. AIMS To summarize the efficacy of treatments aimed at eradicating H. pylori in children and to identify sources of variation in treatment efficacy across studies. METHODS We searched Medline, reference lists from published study reports, and conference proceedings for anti-H. pylori treatment trials in children. Weighted meta-regression models were used to find sources of variation in efficacy. RESULTS Eighty studies (127 treatment arms) with 4436 children were included. Overall, methodological quality of these studies was poor with small sample sizes and few randomized-controlled trials. The efficacy of therapies varied across treatment arms, treatment duration, method of post-treatment assessment and geographic location. Among the regimens tested, 2-6 weeks of nitroimidazole and amoxicillin, 1-2 weeks of clarithromycin, amoxicillin and a proton pump inhibitor, and 2 weeks of a macrolide, a nitroimidazole and a proton pump inhibitor or bismuth, amoxicillin and metronidazole were the most efficacious in developed countries. CONCLUSIONS Before worldwide treatment recommendations are given for eradication of H. pylori, additional well-designed randomized placebo-controlled paediatric trials are needed, especially in developing countries where both drug resistance and disease burden is high.

Abstract
BACKGROUND Few trials of treatment for Helicobacter pylori infection have been conducted in high-prevalence or pediatric populations, and risk factors for treatment failure are poorly understood. METHODS As part of a study evaluating the effect of H. pylori therapy on iron deficiency, we conducted a household-randomized, open-label treatment trial involving children aged 7-11 years in 10 villages in western Alaska. We screened 690 children, of whom 219 with iron deficiency and H. pylori infection (determined on the basis of positive results of the 13C urea breath test) were enrolled in the treatment phase of the study. These 219 children received treatment with iron sulfate alone (the control group) or with iron sulfate combined with a 2-week course of lansoprazole, clarithromycin, and amoxicillin (the intervention group). Children in the intervention group who were allergic to amoxicillin or macrolides received metronidazole. Children in the intervention group who did not respond to treatment were re-treated with a 2-week course of metronidazole-based quadruple therapy. RESULTS Two months after initiating therapy, 34% of 104 children in the intervention group and 0.90% of 111 children in the control group tested negative for H. pylori. Among children in the intervention group, risk factors for treatment failure were lack of metronidazole (adjusted odds ratio [aOR], 145), fewer treatment doses (aOR, 0.74), larger household population (aOR, 1.5), and lower body mass index (aOR, 0.69). These 4 variables predicted most of the variation in H. pylori infection status. Among 50 children who were re-treated, 84% tested negative for H. pylori at the 8-month follow-up visit, including those with poor treatment compliance. CONCLUSIONS Among disadvantaged populations with a high prevalence of H. pylori infection, the response to standard treatment regimens may be low. Treatment compliance, household crowding, and re-treatment may influence treatment success. Metronidazole may be appropriate first-line therapy.

Abstract
GOALS To determine the efficacy of triple therapy supplemented with a specially designed fermented milk product containing specific probiotic Lactobacillus casei (L. casei) DN-114 001 strain on Helicobacter pylori eradication in children. BACKGROUND Lactobacillus species possess in vitro activity against H. pylori. There are no consistent data on the impact of eradication therapy supplemented with probiotics on H. pylori cure rates in childhood in vivo. STUDY Multicenter, prospective, randomized, double-blind controlled study. Eighty-six symptomatic H. pylori-positive children were randomized either to receive the control treatment of omeprazole, amoxicillin, and clarithromycin (OAC) for 7 days or the test treatment of omeprazole, amoxicillin, and clarithromycin for 7 days supplemented with fermented milk (Actimel) containing L. casei DN-114 001 (OAC-LC), for 14 days. H. pylori status was assessed at 4 weeks following therapy using two noninvasive tests. RESULTS Intention-to-treat (ITT) based eradication rates for the OAC-LC group were 84.6% (95% CI, 71.2%-95.5%), and 91.6% (95% CI, 76.9%-98.2%) by per-protocol (PP) analysis. Eradication in the OAC group was 57.5% (95% CI, 42.2%-72.3%) in the ITT set and 61.3% (95% CI, 44.4%-75.0%) in the PP group. Eradication success was higher in the OAC-LC group compared with the OAC group in both ITT (P=0.0045) and PP analysis (P=0.0019). Primary resistance for clarithromycin could be determined in 21.2%. Side effects were infrequent. Drug compliance was good throughout the study. CONCLUSION Supplementation with fermented milk, containing live special probiotic L. casei DN-114 001, confers an enhanced therapeutic benefit on H. pylori eradication in children with gastritis on triple therapy.

Abstract
The diagnosis of Helicobacter pylori infection continues to challenge practicing physicians around the world. In the last year, several reports from Africa tried to examine the epidemiology of H. pylori infection in nursing babies, while others investigated the association between recurrent abdominal pain symptoms and H. pylori. In the diagnostic arena, attempts were made to improve diagnostic accuracy, mainly by using a new monoclonal version of the stool antigen test, and by applying the urea breath test in smaller children. In the current report, the most important studies on H. pylori infection in children published in the last year are also reviewed.

Abstract
The proton pump inhibitors (PPIs) are a relatively new class of agents used for the treatment of acid-related disorders, including peptic ulcer diseases, reflux oesophagitis and Zollinger-Ellison syndrome, and in enhancing antibiotic therapy in the eradication of Helicobacter pylori in patients with peptic ulcer disease. The PPIs are the most potent gastric acid-suppressing agents currently in clinical use. According to the recent basic study, PPIs may act not only as potent acid suppressants, but also as anti-inflammatory or pro-regenerative agents. On the other hand, in the clinical field, general practitioners still tend to prescribe PPIs for unlicensed indications, such as non-ulcer dyspepsia and nonspecific abdominal pain. This article reviews the novel pharmacological action other than acid secretion and the diverse clinical usage of PPIs, in order to seek possible extensions of the use of this unique agent.

Abstract
Helicobacter pylori infection is acquired in childhood and plays a causative role in chronic gastritis, peptic ulcer disease and the development of gastric cancer. The present review focuses on recent advances in the management of H pylori infection in children and provides an update of current Canadian guidelines regarding clinical sequelae, diagnosis and treatment.
