Helicobacter 2021; 26:e12852. [PMID: 34510644 DOI: 10.1111/hel.12852] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/03/2021] [Revised: 08/23/2021] [Accepted: 08/26/2021] [Indexed: 12/18/2022]
Abstract
OBJECTIVE To update and evaluate the recurrence rate of Helicobacter pylori (H. pylori) eradication therapy in recent 10 years. METHODS A systematic search of PubMed, Embase, Cochrane library, and Web of science was performed to identify the studies of recurrence rate of H. pylori published from 2010 to 2019. Stata 15.0 was used for analysis. RESULTS A total of 31 studies (16,797 participants) were analyzed. The recurrence rate of H. pylori was 9% (95% CI, 8-11%), and it showed an upward trend with the time elapsed after eradication. The annual recurrence rate was 4%, and there was a stable trend with the time elapsed after eradication. Subgroup analyses showed that the recurrence rate of H. pylori eradication by triple therapy was higher than that of quadruple therapy (14% [95% CI, 9-19] vs 12% [95% CI, 7-17]); urban was higher than that of rural (8% [95% CI, 1-14] vs 5% [95% CI, 1-9]); males were higher than that of females (11% [95% CI, 8-14] vs 10% [95% CI, 7-14]); Europe had the highest recurrence rate (16% [95% CI, -1 to 42]), and Africa had the lowest (1% [95% CI, 0-2]). The recurrence rate ofH. pylori was inversely related to the human development index. CONCLUSIONS The recurrence rate of H. pylori showed an increasing trend in recent 10 years, and it is still a knotty public health problem worldwide. The recurrence rate of H. pylori showed an upward trend with the time elapsed after eradication, and the recurrence rate of H. pylori varies by area, gender, and eradication methods.

Evaluation of the Effectiveness of Helicobacter pylori Eradication Regimens in Lithuania during the Years 2013-2020: Data from the European Registry on Helicobacter pylori Management (Hp-EuReg). ACTA ACUST UNITED AC 2021; 57:medicina57070642. [PMID: 34201428 PMCID: PMC8305910 DOI: 10.3390/medicina57070642] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/23/2021] [Revised: 06/10/2021] [Accepted: 06/15/2021] [Indexed: 12/11/2022]
Abstract
Background and Objectives: The prevalence of H. pylori in Eastern Europe remains quite high; however, there is insufficient data on the eradication regimens and their effectiveness. Therefore, the objective of the study was to evaluate the diagnostic methods and treatment of H. pylori infection as well as their adherence to Maastricht V/Florence consensus during the years 2013–2020 in Lithuania. Materials and Methods: Sub-study of the “European Registry on H. pylori Management” (Hp-EuReg), international multicenter prospective non-interventional registry of the routine clinical practice. Lithuanian data from the years 2013–2020 were analyzed for effectiveness on a modified intention-to-treat (mITT) basis. 2000 adult patients, diagnosed with H. pylori infection, were included. Data were compared to the European Maastricht V guidelines. Results: Triple-therapy was used in 90% of the cases. In 91% of the first-line prescriptions, standard triple therapy (STT) was used. The most common second-line treatment was a combination of PPI, amoxicillin and levofloxacin (PPI+A+L) (47%). The overall effectiveness in 552 cases valid for analysis was 90% by mITT. In first-line treatment, the STT effectiveness was 90% and second-line treatment with PPI+A+L achieved 92% by mITT. Increasing overall H. pylori eradication rates were observed: from 72% in 2013 to more than 90% in 2018–2020, as well as a shift from 7 to 10–14 days treatments duration throughout 2013–2020. Conclusions: In Lithuania, the prescribed eradication regimens for H. pylori were in accordance with the international guidelines but diagnostic methods and treatment duration only partially met Maastricht V/Florence guidelines. The eradication effectiveness was improved progressively during the years 2018–2020, reaching ≥90% cure rates.

Curr Pharm Biotechnol 2021; 22:945-959. [PMID: 32767919 DOI: 10.2174/1389201021666200807110849] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/15/2020] [Revised: 06/30/2020] [Accepted: 07/04/2020] [Indexed: 11/22/2022]
Abstract
BACKGROUND Helicobacter pylori causes dangerous and deadly diseases such as gastric cancer and duodenal ulcers. Eradication and treatment of this bacterium are very important due to the deadly diseases caused by H. pylori and the high cost of treatment for countries. METHODS Thus, we present a complete list of the most important causes of failure in the treatment and eradication of H. pylori, and address new therapeutic methods that may be effective in controlling this bacterium in the future. RESULTS Many efforts have been made to control and eradicate this bacterium over the years, but no success has been achieved since its eradication is a complex process affected by the bacterial properties and host factors. Previous studies have shown that various factors are involved in the failure to eradicate H. pylori, such as new genotypes of the bacterium with higher pathogenicity, inappropriate patient cooperation, mutations, biofilm formation and dormant forms that cause antibiotic resistance, acidic stomach pH, high bacterial load, smoking, immunosuppressive features and intracellular occurrence of H. pylori. On the other hand, recent studies reported that the use of probiotics, nanoparticles, antimicrobial peptides, natural product and vaccines can be helpful in the treatment and eradication of H. pylori infections. CONCLUSION Eradication of H. pylori is crucial for the treatment of important diseases such as gastric cancer. Therefore, it seems that identifying the failure causes of treating this bacterium can be helpful in controlling the infections. Besides, further studies on new therapeutic strategies may help eradicate H. pylori in the future.

Hu Y, Zhu Y, Lu NH. Novel and Effective Therapeutic Regimens for Helicobacter pylori in an Era of Increasing Antibiotic Resistance. Front Cell Infect Microbiol 2017; 7:168. [PMID: 28529929 PMCID: PMC5418237 DOI: 10.3389/fcimb.2017.00168] [Citation(s) in RCA: 89] [Impact Index Per Article: 12.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/14/2016] [Accepted: 04/18/2017] [Indexed: 01/06/2023] Open
Abstract
Helicobacter pylori (H. pylori) is a common gastrointestinal bacterial strain closely associated with the incidence of chronic gastritis, peptic ulcers, gastric mucosa-associated lymphoid tissue lymphoma, and gastric cancer. A current research and clinical challenge is the increased rate of antibiotic resistance in H. pylori, which has led to a decreased H. pylori eradication rate. In this article, we review recent H. pylori infection and reinfection rates and H. pylori resistance to antibiotics, and we discuss the pertinent treatments. A PubMed literature search was performed using the following keywords: Helicobacter pylori, infection, reinfection, antibiotic resistance, bismuth, proton pump inhibitors, vonoprazan, susceptibility, quintuple therapy, dual therapy, and probiotic. The prevalence of H. pylori has remained high in some areas despite the decreasing trend of H. pylori prevalence observed over time. Additionally, the H. pylori reinfection rate has varied in different countries due to socioeconomic and hygienic conditions. Helicobacter pylori monoresistance to clarithromycin, metronidazole or levofloxacin was common in most countries. However, the prevalence of amoxicillin and tetracycline resistance has remained low. Because H. pylori infection and reinfection present serious challenges and because H. pylori resistance to clarithromycin, metronidazole or levofloxacin remains high in most countries, the selection of an efficient regimen to eradicate H. pylori is critical. Currently, bismuth-containing quadruple therapies still achieve high eradication rates. Moreover, susceptibility-based therapies are alternatives because they may avoid the use of unnecessary antibiotics. Novel regimens, e.g., vonoprazan-containing triple therapies, quintuple therapies, high-dose dual therapies, and standard triple therapies with probiotics, require further studies concerning their efficiency and safety for treating H. pylori.

[PMID: 28440977 PMCID: PMC5464486 DOI: 10.22034/apjcp.2017.18.3.695] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 01/14/2023] Open
Abstract
Background: H. pylori is an important cause of chronic gastritis, peptic ulcers and gastric cancer. Re-infection rates after successful eradication vary in different regions of the world but only limited studies have been performed in ASEAN Countries to clarify this important issue. The present study was designed to evaluate the H. pylori re-infection rate and predictors of re-infection in Thailand. Methods: We recruited patients with chronic gastritis after 1 and 2 years successful H. pylori eradication from Thammasat University Hospital, Pathumthani (Central urban area) and Maesod district, Tak (Northern rural area), Thailand. 13C-UBT was performed to evaluate re-infection status after cessation of PPI, H2 blocker and antibiotics for at least 4 weeks. Statistical analysis was performed using SPSS for Windows Version 22.0 (IBM Corp., Armonk, NY). Results: A total of 105 subjects were enrolled (40 M and 65F with a mean age of 53.1 years). The overall re-infection rate was 6/105 (5.7%). The 1-year and 2-year H. pylori re-infection rates after successful eradication were only 5.1% (2/39) and 6.1% (4/66). 1-year and 2-year reinfection rates in urban areas were 2/39 (5.1%) and 1/26 (3.8%), while the 2-year reinfection rate in rural areas was 3/40 (7.5%). Location (urban vs rural area) and sex did not show any association with either 1-year or 2-year H. pylori re-infection. With 2-year reinfection, the mean age of H. pylori re-infected patients was significantly higher than those who remained cured (63.0 years vs. 51.6 years, p-value = 0.01). The annual H. pylori infection rate was 2.9%. Conclusions: 1-year and 2-year H. pylori re-infection rates after successful eradication in Thailand appear low in both rural and urban areas. H. pylori eradication for prevention of significant upper GI disease should be recommended and confirmation of successful eradication should be the aim. Patients at higher risk such as the elderly should be monitored for possible risk of H. pylori re-infection.
