Miao R, Chen J, Gao S, Wang L, Zhou W, Wan C, Wang Z. 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
Background Multiple regimens have been widely used in the eradication treatment of Helicobacter pylori infection in children. However, there is a lack of comparison and evaluation of their effectiveness in different regions of the world. Methods Randomized controlled trials were retrieved. Review Manager 5.4, Stata SE 15 and R 4.0.4 statistical software were used to analyze date. The ranking probability is assessed according to the surfaces under cumulative ranking (SUCRA). Results 163 studies were eligible for this study, involving 336 arms and 18,257 children, and 10 different interventions. The results showed that the eradication rates of sequential therapy with probiotics (SP), bismuth-containing quadruple (Quadruple) therapy, concomitant therapy and PCN therapy were at least 90%. Cumulative ranking showed that SP therapy had the best eradication effect (SUCRA 92.7%) whereas Bismuth-containing triple therapy (B) had the worst (SUCRA 3.5%). Subgroup analysis suggested that SP therapy ranked first in China and other regions, and the ranking of Triple therapy with probiotics therapy (TP) was equally stable (SUCRA 72.0% vs 76.4% respectively). The security of the SP and TP therapy had great advantages. Conclusions As for the eradication treatment of Helicobacter pylori infection in children, SP therapy ranks highest. SP and TP therapies are most safe.

World J Clin Cases 2022; 10:12959-12970. [PMID: 36569016 PMCID: PMC9782940 DOI: 10.12998/wjcc.v10.i35.12959] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/16/2022] [Revised: 10/08/2022] [Accepted: 11/30/2022] [Indexed: 12/14/2022] Open
Abstract
BACKGROUND As a first-line treatment regimen for Helicobacter pylori (H. pylori) infection, antibiotic therapy is widely used worldwide. However, the question of increasing antibiotic resistance must be considered. Given this issue, we need to find ways to reduce drug resistance. This study examined all currently available first-line regimens and compared them with standard triple treatment through a network meta-analysis of randomized controlled trials (RCTs).
AIM To compare first-line treatment regimens for eradication of antibiotic-resistant H. pylori strains.
METHODS To compare the effectiveness of the first-line regimens for treating H. pylori infection, a Bayesian network meta-analysis was applied to process data extracted from RCTs. The plausible ranking for each regimen was assessed by the surface under the cumulative ranking curve (SUCRA). In addition, we conducted a relevant search by reference citation analysis.
RESULTS Twenty-five RCTs involving 12029 participants [including 1602 infected with clarithromycin (CAM)-resistant strains and 1716 infected with metronidazole (MNZ)-resistant strains] were included, in which a total of seven regimens were used for H. pylori eradication. The results showed that dual therapy containing a high-dose proton pump inhibitor (HDDT) [odds ratio (OR): 4.20, 95% confidence interval (CI): 2.29-8.13] was superior to other therapies for all patients, including those with CAM/MNZ-resistant H. pylori infection. In the comparative effectiveness ranking, for CAM-resistant H. pylori, HDDT (OR: 96.80, 95%CI: 22.46-521.9) had the best results, whereas standard triple therapy ranked last (SUCRA: 98.7% vs 0.3%). In the subgroup of high cure rates (≥ 90%), HDDT was also generally better than other therapies.
CONCLUSION For the eradication of CAM- and MNZ-resistant H. pylori strains, HDDT exhibited considerable advantages. The studies of CAM-resistant H. pylori were based on small samples due to a lack of antibiotic sensitivity tests in many RCTs, but the results showed that all patients, including those with CAM-resistant H. pylori infection, had a concordant trend. Overall, HDDT may be a reference for RCTs and other studies of H. pylori eradication.

Abstract
Abstract
Objective There are many adverse effects of drugs used to eradicate Helicobacter pylori, and reconstructing the microbiota by external ingestion of probiotics seems to have good effects on H. pylori eradication and prevents side effects.
Methods The study included 161 outpatients aged between 8 and 18 years diagnosed with H. pylori gastritis in the Gülhane Training and Research Hospital Pediatric Gastroenterology unit from June 1, 2018, through March 31, 2020, and patients were randomized into two groups. Eighty patients in the probiotic group (first group) received H. pylori eradication therapy for 14 days; additionally, Bifidobacterium lactis B94 was administered for 14 days for eradication of H. pylori. Eighty-one patients in the standard therapy group (second group) received the same eradication therapy but no probiotics. All patients were asked to complete a detailed questionnaire regularly, including changes in symptoms and side effects of drugs on days 0, 7, and 14 of treatment. The eradication success was checked with the H. pylori stool antigen test kit 8 weeks after completion of the treatment regimen.
Results The mean age of the patients was 14.2 ± 2.9 years, and 88 (64.7%) were female. The eradication rates were similar between the standard therapy and the probiotic groups by intention-to-treat analysis (p = 0.930). In order of frequency, the most common eradication treatment–related side effects were abdominal pain, taste abnormalities, and anorexia. In addition, therapy-related epigastric pain and flatulence were similar initially (p > 0.05) but seemed to be significantly lower in the probiotic group than in the standard therapy group on days 7 and 14 (p < 0.05).
Conclusions Our results suggest that additional probiotic supplementation has not changed the eradication rates but seems to reduce some specific gastrointestinal adverse events in children with H. pylori infections treated with a bismuth-based quadruple eradication regimen. More extensive randomized controlled trials are needed to explain probiotics' effects on H. pylori eradication and drug side effects.

Diagnostics (Basel) 2022; 12:diagnostics12092119. [PMID: 36140521 PMCID: PMC9497693 DOI: 10.3390/diagnostics12092119] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/15/2022] [Revised: 08/26/2022] [Accepted: 08/29/2022] [Indexed: 11/16/2022] Open
Abstract
Reports have indicated an increasing prevalence of clarithromycin resistance in children relative to adults. Thus, it is important to investigate primary clarithromycin resistance before therapy to avoid treatment failure. A2142G, A2143G, and A2142C point mutations in the peptidyltransferase region of the 23S ribosomal RNA (rRNA) of Helicobacter pylori (H. pylori) strains isolated from children with gastrointestinal symptoms and asymptomatic children were evaluated via real-time polymerase chain reaction (RT-PCR) using fecal DNA samples. The presence of H. pylori was determined using a fecal H. pylori antigen enzyme-linked immunosorbent assay (ELISA) kit from the stools of children (n = 543). A2143G, A2142C, and A2142G point mutations were detected via RT-PCR and confirmed by sequencing the 23S rDNA. Fecal H. pylori antigen testing was positive in 101 symptomatic (49) and asymptomatic (52) children. A significant difference was found between the 0–5- and 5–18-year-old groups in terms of the A2143G and A2142G point mutations (p = 0.001). The A2142C mutation was not detected. There was a significant difference in the A2143G mutation between the symptomatic and asymptomatic 5–18-year-old children (p = 0.019). Macrolides are frequently used to treat upper respiratory tract infections in children due to their selective pressure effect. We suggest that H. pylori strains carrying mutations in the 23S RNA subunit conferring clarithromycin resistance may lead to an intense inflammatory response in the gastric epithelial cells, allowing them to proliferate more rapidly and causing possible diarrhea, halitosis, or abdominal pain in children.

Abstract
Helicobacter pylori infection can cause gastritis, gastric or duodenal ulcers, mucosa-associated lymphoid tissue lymphoma, gastric cancer, and extra-gastrointestinal manifestations. Ideal treatment should be guided by antibiotic susceptibility testing. However, this is not feasible in many regions, so the treatment generally relies on clinical experience and regional culture sensitivity profiles. We aimed to integrate the treatment of pediatric H. pylori infection through a systematic literature review. Databases including PubMed, Cochrane Library, EMBASE, and Scholar were searched using terms containing (Helicobacter OR Helicobacter pylori OR H. pylori) AND (child OR pediatric) for all relevant manuscripts and guidelines, published from January 2011 to December 2021. The eradication rate for pediatric H. pylori infection was not satisfactory using triple therapy, sequential therapy, concomitant therapy, bismuth-based quadruple therapy, or adjuvant therapy with probiotics as the first-line therapy. Most therapies could not achieve the recommended eradication rate of >90%, which may be attributed to varying regional antibiotic resistance and possible poor children’s compliance. More studies are required to establish a best practice for pediatric H. pylori infection treatment.

Abstract
BACKGROUND/PURPOSE Helicobacter pylori infection is one of the most common causes of peptic ulcer disease among children. This study is aimed to investigate the eradication rate of 14-day sequential therapy and the antibiotic resistance of H. pylori in children. METHODS Eighty-seven treatment-naïve children (55 males; median age, 13.5 years) with H. pylori infection from January 2009 to August 2019 were recruited in this study. The status of H. pylori infection was confirmed by culture or histology with the aid of urea rapid test or C-13 urea breathe test. Patients treated with either triple therapy for 7 days or 14 days, or sequential therapy for 14 days was analyzed retrospectively. RESULTS Thirty-eight (43.7%) patients received 14-day sequential therapy, 24 (27.6%) patients received 14-day triple therapy and the remaining 25 (28.7%) patients received 7-day triple therapy. The eradication rate of 14-day sequential therapy was significantly superior to 7-day triple therapy (97.4% vs. 80%, p = 0.032), and tended to be better than 14-day triple therapy (83%, p = 0.07). Of the 54 patients with available antibiotic resistance data, the resistant rate of clarithromycin, metronidazole, levofloxacin, and amoxicillin were 22.2%, 16.7%, 9.1% and 2.2%, respectively. Clarithromycin resistance demonstrated an inverse association with eradication success (Odds ratio = 0.017, p < 0.001). CONCLUSIONS In treatment-naïve children with H. pylori infection, 14-day sequential therapy is superior to triple therapy, and achieve a high eradication rate (above 90%) in an area of high clarithromycin resistance.

Abstract
BACKGROUND Antimicrobial resistance of Helicobacter pylori reduces the eradication rate. This study aimed to investigate changes in antimicrobial susceptibility of H pylori isolated from children in Taiwan in the past two decades. METHODS This study enrolled children receiving esophagogastroduodenoscopy for upper gastrointestinal diseases in a national tertiary referring hospital from 1998 to 2018. H pylori infection was diagnosed by culture. The minimal inhibitory concentrations (MICs) of antibiotics were tested using the E test. The antibiotic resistance rates and MICs of amoxicillin, clarithromycin, metronidazole, levofloxacin, and tetracycline were compared between 1998-2008 and 2009-2018. RESULTS A total of 70 Helicobacter pylori isolates (29 from 1998 to 2008 and 41 from 2009 to 2018) were identified. The esophagogastroduodenoscopy findings included duodenal ulcers (n = 31), gastric ulcers (n = 9), and gastritis (n = 30). The overall antimicrobial resistance rates of clarithromycin and metronidazole were 22.9% and 21.4%, respectively. The dual resistance rate of clarithromycin and metronidazole was 10%. Resistance rates of levofloxacin and amoxicillin were 8.3% and 2.9%, respectively. None of the isolates were resistant to tetracycline. Compared with the isolates from 1998 to 2008, those from 2009 to 2018 had higher MICs and resistance rates of clarithromycin (26.8% vs 17.2%, P = 0.35) and metronidazole (26.8% vs 13.8%, P = 0.19), but not levofloxacin (9.8% vs 5.3%, P = 1.0) or coresistance to clarithromycin and metronidazole (12.2% vs 6.9%, P = 0.69). CONCLUSIONS The antimicrobial resistance rates of pediatric H pylori isolates to clarithromycin and metronidazole increased during the past decade. The selection of antimicrobial agents other than clarithromycin and metronidazole is crucial to increase pediatric H pylori eradication rates.

Abstract
BACKGROUND Helicobacter pylori antimicrobial resistance is gradually increasing around the world. However, there are a limited number of studies reporting on this issue in the pediatric population. In this study, we aimed to determine H pylori resistance to clarithromycin and fluoroquinolones in the pediatric patients living in Kırıkkale province that were detected with H pylori in gastric biopsies. Moreover, we also aimed to investigate the concordance between the histopathologic and molecular methods used in the diagnosis of H pylori infection. MATERIALS AND METHODS Patients aged 2-18 years who had a history of epigastric pain and/or nausea persisting for longer than 1 month underwent upper gastrointestinal endoscopy. Biopsies were taken from the gastric antral mucosa. In the samples detected with H pylori in the histopathologic examination, the presence of H pylori and H pylori resistance to clarithromycin and fluoroquinolones was investigated using the GenoType HelicoDR test which allows the detection of wild-type and mutant genes. The strains detected with more than one mutant gene are defined as hetero-resistant strains. RESULTS The 93 patients that underwent DNA extraction and amplification included 68 (73.1%) girls and 25 (26.9%) boys with a median age of 15 ± 2.62 (range 6-17) years. The overall concordance for the diagnosis of H pylori infection between histopathology and PCR was 94%, and H pylori resistance to clarithromycin and fluoroquinolones was 27% and 15%, respectively. CONCLUSIONS The high H pylori resistance to clarithromycin and fluoroquinolones among the pediatric patients in our region implicates that the antibiotic sensitivity of strains should be studied prior to administration in accordance with the recommendations provided in the guidelines. Moreover, the presence of hetero-resistant strains in our patients may be a reason for treatment failure.

Abstract
BACKGROUND & AIMS In 2017, the World Health Organization (WHO) designated clarithromycin-resistant Helicobacter pylori a high priority for antibiotic research and development. However, there are no clear data on the global distribution of resistance or its clinical effects. We performed a systematic review and meta-analysis to assess the distribution of H pylori resistance to commonly used antibiotics and to measure the association between antibiotic resistance and treatment failure. METHODS We searched publication databases for studies that assessed rates of H pylori resistance to clarithromycin, metronidazole, levofloxacin, amoxicillin, or tetracycline. Pooled estimates of primary and secondary resistance and 95% confidence intervals (CIs) were grouped by WHO region. The association between antibiotic resistance and treatment failure was measured by extracting data on treatment efficacy in patients with resistant and susceptible isolates and pooling odds ratios with 95% CIs. RESULTS We identified 178 studies, comprising 66,142 isolates from 65 countries. Primary and secondary resistance rates to clarithromycin, metronidazole, and levofloxacin were ≥15% in all WHO regions, except primary clarithromycin resistance in the Americas (10%; 95% CI, 4%-16%) and South-East Asia region (10%; 95% CI, 5%-16%) and primary levofloxacin resistance in the European region (11%; 95% CI, 9%-13%). There was considerable heterogeneity (I2 > 75%) among all analyses-this might have resulted from the grouping of resistance rates by country. Increasing antibiotic resistance was observed in most WHO regions. Resistance to clarithromycin was significantly associated with failure of clarithromycin-containing regimens (odds ratio, 6.97; 95% CI, 5.23-9.28; P < .001). CONCLUSIONS Resistance of H pylori to antibiotics has reached alarming levels worldwide, which has a great effect on efficacy of treatment. Local surveillance networks are required to select appropriate eradication regimens for each region.

The Effects of Synbiotic " Bifidobacterium lactis B94 plus Inulin" Addition on Standard Triple Therapy of Helicobacter pylori Eradication in Children. Can J Gastroenterol Hepatol 2017; 2017:8130596. [PMID: 28656129 PMCID: PMC5471574 DOI: 10.1155/2017/8130596] [Citation(s) in RCA: 20] [Impact Index Per Article: 2.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/25/2017] [Accepted: 05/07/2017] [Indexed: 02/08/2023] Open
Abstract
AIM The aim of this study is to evaluate the effects of the synbiotic Bifidobacterium lactis B94 plus inulin addition to the standard triple therapy on Helicobacter pylori (H. pylori) infection eradication rates. METHODS Children aged 6-16 years who had biopsy proven H. pylori infection were randomly classified into two groups. The first group received the standard triple therapy consisting of amoxicillin + clarithromycin + omeprazole. The second group was treated with the standard triple therapy and Bifidobacterium lactis B94 (5 × 109 CFU/dose) plus inulin (900 mg) for 14 days, concurrently. Eradication was determined by 14C-urea breath test 4-6 weeks after therapy discontinuation. RESULTS From a total of 69 H. pylori infected children (F/M = 36/33; mean ± SD = 11.2 ± 3.0 years), eradication was achieved in 20/34 participants in the standard therapy group and 27/35 participants in the synbiotic group. The eradication rates were not significantly different between the standard therapy and the synbiotic groups [intent-to-treat, 58.8% and 77.1%, resp., p = 0.16; per-protocol, 64.5% and 81.8%, resp., p = 0.19]. There was no difference between the groups in terms of symptom relief (p = 0.193). The reported side effects were ignorable. CONCLUSION Considering the eradication rates, synbiotic addition to therapy showed no superiority over the standard triple therapy conducted alone. This trial is registered with NCT03165253.

Abstract
Introduction Helicobacter pylori colonization is present in half of the world’s population and can lead to numerous gastrointestinal diseases if left untreated, including peptic ulcer disease and gastric cancer. Although concurrent triple therapy remains the recommended treatment regimen for H. pylori eradication, its success rate and efficacy have been declining. Recent studies have shown that the addition of probiotics can significantly increase eradication rates by up to 50%. This meta-analysis examines the impact of probiotic supplementation on the efficacy of standard triple therapy in eradicating H. pylori. Methods A comprehensive literature search was conducted using PubMed, Cochrane Central Registry of Controlled Trials, and Google Scholar (time of inception to 2016) to identify all published randomized control trials (RCTs) assessing the use of probiotics in addition to triple therapy for the treatment of H. pylori. Searches were conducted using the keywords “probiotics”, “triple therapy”, and “Helicobacter pylori”. RCTs comparing the use of probiotics and standard triple therapy with standard triple therapy alone for any duration in patients of any age diagnosed with H. pylori infection were included. H. pylori eradication rates (detected using urea breath test or stool antigen) were analyzed as-per-protocol (APP) and intention-to-treat (ITT). Results A total of 30 RCTs involving 4,302 patients APP and 4,515 patients ITT were analyzed. The addition of probiotics significantly increased eradication rates by 12.2% (relative risk [RR] =1.122; 95% confidence interval [CI], 1.091–1.153; P<0.001) APP and 14.1% (RR =1.141; 95% CI, 1.106–1.175; P<0.001) ITT. Probiotics were beneficial among children and adults, as well as Asians and non-Asians. No significant difference was observed in efficacy between the various types of probiotics. The risk of diarrhea, nausea, vomiting, and epigastric pain was also reduced. Conclusion The addition of probiotics is associated with improved H. pylori eradication rates in both children and adults, as well as Asians and non-Asians. Lactobacillus, Bifidobacterium, Saccharomyces, and mixtures of probiotics appear beneficial in H. pylori eradication. Furthermore, the reduction in antibiotic-associated side effects such as nausea, vomiting, diarrhea, and epigastric pain improves medication tolerance and patient compliance. Given the consequences associated with chronic H. pylori infection, the addition of probiotics to the concurrent triple therapy regimen should be considered in all patients with H. pylori infection. However, further studies are required to identify the optimal probiotic species and dose.

Abstract
Helicobacter pylori (H. pylori) is an important cause for gastric cancer in high risk individuals. H. pylori colonizes more than 50% of the world’s population and associated peptic ulcer disease and gastric malignancy have important public health implications. It has been classified as a class I carcinogen in 1994 by the World Health Organization. Clinicians are often prompted to eliminate the infection the moment it is detected. This also, unfortunately, led to reckless use of antibiotics and reports of increasing resistance are now worldwide. Each year, many of people die from gastric cancer; thus application of effective vaccine can reduce this relatively high mortality worldwide. H. pylori can be eliminated by antibiotics but efficacy is sharply decreasing. Moreover, current therapy is also expensive and with side effects. Vaccine may be the best solution to the above problem but there are many challenges in producing such an effective therapeutic vaccine. Recently, the Chinese group published in Lancet, a single-center, randomized, phase III study of an oral recombinant vaccine (Urease B subunit fused with heat-labile enterotoxin B derived from Escherichia coli) prescribed in the Chinese children (6-15 years) without a history of H. pylori infection. This review provides an insight into this new solution for an old challenge.

Abstract
Helicobacter pylori is a common infection associated with many gastrointestinal diseases. Triple or quadruple therapy is the current recommendation for H pylori eradication in children but is associated with success rates as low as 50%. Recent studies have demonstrated that a 10-day sequential therapy regimen, rather than simultaneous antibiotic administration, achieved eradication rates of nearly 95%. This meta-analysis found that sequential therapy increased eradication rates by 14.2% (relative risk [RR] = 1.142; 95% confidence interval [CI] = 1.082-1.207; P < .001). Ten-day sequential therapy significantly improved H pylori eradication rates compared to the 7-day standard therapy (RR = 1.182; 95% CI = 1.102-1.269; p < .001) and 10-day standard therapy (RR = 1.179; 95% CI = 1.074-1.295; P = .001), but had lower eradication rates compared to 14-day standard therapy (RR = 0.926; 95% CI = 0.811-1.059; P = .261). The use of sequential therapy is associated with increased H pylori eradication rates in children compared to standard therapy of equal or shorter duration.

Abstract
OBJECTIVES To assess the efficacy and safety of 10-d sequential therapy compared to 5 to 14-d triple therapy for treating Helicobacter pylori infections in children according to the eradication rates. METHODS The Cochrane Library, MEDLINE, EMBASE, China National Knowledge Infrastructure databases, and other sources were searched in November 2014 without language restrictions. Randomized controlled trials (RCTs) that compared sequential therapy with triple therapy for H. pylori eradication in children were included. Dichotomous data were pooled to obtain the relative risk (RR) of the eradication rate with a 95% confidence interval (CI). RESULTS Fourteen RCTs with 1698 participants (718 and 980 for sequential and triple therapy, respectively) were included. The intention-to-treat eradication rates were 73% (95% CI: 70-76) and 66% (95% CI: 64-70) for sequential and triple therapy, respectively. The pooled RR was 1.16 (95% CI: 1.09-1.23), resulting in a number needed to treat of 16 (95% CI: 10-48), favoring sequential therapy. Sequential therapy was superior to 7- and 10-d triple therapy. Sequential and triple therapy did not differ significantly in the overall risk of adverse effects. CONCLUSIONS In children, sequential therapy appears to be superior to triple therapy for H. pylori eradication, although the eradication rates remain lower than the expected goal with both treatments. Factors-associated with a higher risk of eradication failure, such as compliance and antimicrobial resistance, remain insufficiently investigated. Therefore, further high-quality RCTs are needed to compare these different eradication treatment approaches.

Abstract
Infection with the Gram-negative pathogen Helicobacter pylori (H. pylori) has been associated with gastro-duodenal disease and the importance of H. pylori eradication is underscored by its designation as a group I carcinogen. The standard triple therapy consists of a proton pump inhibitor, amoxicillin and clarithromycin, although many other regimens are used, including quadruple, sequential and concomitant therapy regimens supplemented with metronidazole, clarithromycin and levofloxacin. Despite these efforts, current therapeutic regimens lack efficacy in eradication due to antibiotic resistance, drug compliance and antibiotic degradation by the acidic stomach environment. Antibiotic resistance to clarithromycin and metronidazole is particularly problematic and several approaches have been proposed to overcome this issue, such as complementary probiotic therapy with Lactobacillus. Other studies have identified novel molecules with an anti-H. pylori effect, as well as tailored therapy and nanotechnology as viable alternative eradication strategies. This review discusses current antibiotic therapy for H. pylori infections, limitations of this type of therapy and predicts the availability of newly developed therapies for H. pylori eradication.

Abstract
This review includes the main pediatric studies published from April 2014 to March 2015. The host response of Treg cells with increases in FOXP3 and TGF-β1 combined with a reduction in IFN-γ by Teff cells may contribute to Helicobacter pylori susceptibility in children. Genotypic variability in H. pylori strains influences the clinical manifestation of the infection. Helicobacter pylori infection is associated with variables indicative of a crowded environment and poor living conditions, while breast-feeding has a protective effect. Intrafamilial infection, especially from mother to children and from sibling to sibling, is the dominant transmission route. Studies showed conflicting results regarding the association between H. pylori infection and iron deficiency anemia. One study suggests that H. pylori eradication plays a role in the management of chronic immune thrombocytopenic purpura in H. pylori-infected children and adolescents. The prevalence of H. pylori was higher in chronic urticaria patients than in controls and, following H. pylori eradication, urticarial symptoms disappeared. An inverse relationship between H. pylori infection and allergic disease was reported. Antibiotic resistance and insufficient compliance to treatment limit the efficacy of eradication therapy. Sequential therapy had no advantage over standard triple therapy. In countries where H. pylori infection is prevalent, studies focusing on virulence factors and antibiotic susceptibility may provide anticipation of the prognosis and may be helpful to reduce morbidity and mortality.

Abstract
BACKGROUND AND AIM Eradication of Helicobacter pylori (H. pylori) infection with triple therapy (TT) has declined in many countries prompting the search for alternative regimens. Sequential therapy (ST) and concomitant therapy (CT) have been suggested as first-line regimens in areas of high clarithromycin resistance. We performed a meta-analysis to compare the eradication rates of CT with ST for H. pylori. METHODS A comprehensive literature search for studies comparing the efficacy of CT with ST was performed. Dichotomous data were pooled to obtain the odds ratio (OR) of the eradication rate with 95% confidence intervals (CIs). The eradication rates were considered both on an intention-to-treat (ITT) and on a per-protocol (PP) bases. RESULTS A total of 7 studies provided data on 2412 adult patients. Pooled estimates of the studies revealed no significant differences between CT and ST. The pooled OR was 1.116 (95% CI: 0.795-1.567, P = 0.526) for ITT analysis and 1.153 (95% CI: 0.793-1.677, P = 0.455) for PP analysis. There was no difference in the rate of adverse events (OR: 1.229, 95% CI: 0.971-1.556, P = 0.086) and compliance (OR: 0.945, 95% CI: 0.722-1.237, P = 0.681) between the two regimens. Subgroup analysis was performed to compare CT of 10 days and 5 days with ST of 10 days. The pooled OR was 1.518 for CT of 10 days and 0.636 for CT of 5 days. CONCLUSIONS CT regimens did not achieve higher eradication rates compared with the ST regimen. The adverse events and adherence to medications were not different between the two regimens.
