As a library, NLM provides access to scientific literature. However, the role of sequential therapy in H. pylori eradication is diminishing according to Western guidelines[52]. H.pylori có thể lây lan bằng cách ăn uống thức ăn hoặc nước bị nhiễm qua phân. H.pylori can cause stomach inflammation (gastritis) and more serious conditions such as stomach ulcers and stomach cancer. Adverse drug events occurred less frequently with tailored eradication than BQT (12.0% vs 43.7%, P < 0.001). In a meta-analysis by Shinozaki et al[45], VPZ was more efficacious for second-line H. pylori eradication compared to conventional PPIs. Cell surface binding and vacuolating activity of the toxin arise from the middle region [164, 165]. The organism can survive in the presence of a low level of oxygen. Consistency of Helicobacter pylori eradication rates of first-line concomitant and sequential therapies in Korea: A nationwide multicenter retrospective study for the last 10 years. The organism belongs to several distinct genetic populations which shows high genetic diversity [1, 2]. The spiral form of H. pylori is culturable. Flagella enable the migration of the pathogenic bacterium from entry to the mucus membrane, where it produces an adhesin to colonize the mucus lining of the host’s epithelial cells [11]. Bacterial CagA protein compromises tumor suppressor mechanisms in gastric epithelial cells. Clinical trials with DT involving frequent administration of high-dose AMX have been widely performed in the Chinese population. Among the antibiotic combinations, the LVFX-containing regimen is not recommended as an initial treatment due to a high resistance rate[33]. These genes code for adhesion proteins such as the BabA/B/C, SabA/B, and AlpA/B. Structural, enzymatic and biochemical studies on, Morishita K, Takeuchi H, Morimoto N, Shimamura T, Kadota Y, Tsuda M, Sugiura T. Superoxide dismutase activity of. Nhiễm bệnh có thể không có triệu chứng hoặc gây khó tiêu với các mức độ khác nhau. This flagellum also protects the bacterium from the gastric environment [10]. Liu WZ, Xie Y, Lu H, Cheng H, Zeng ZR, Zhou LY, Chen Y, Wang JB, Du YQ, Lu NH Chinese Society of Gastroenterology, Chinese Study Group on Helicobacter pylori and Peptic Ulcer. Seven-day triple therapy is sufficient to eradicate infection caused by Helicobacter pylori without 23S rRNA point mutation. The recommended H. pylori treatment regimens differ among those three East Asian countries. As first-line treatment, standard triple therapy containing 20 mg VPZ twice daily resulted in higher H. pylori eradication rates than those of a PPI-based regimen (86.4%-91.2% vs 71.7%-79.4%)[38,39]. H. pylori eradication rates were 87.3% and 76.5% (P = 0.21) in the ITT analysis, and 88.9% and 86.7% (P = 0.77) in the PP analysis, respectively[40]. SVNCF bacteria still maintain their metabolic activity and pathogenicity and can return to active, viable culturable conditions [127, 128]. The Potential Benefits of Vonoprazan as. Epidemiologically, 85–95% of developing countries’ population has H. pylori infection and approximately 30–50% in developed countries [25–28]. Heterogeneity of, Tag Eldeen LAT, Mohamed MA, Awad MM, Sheir MI, Shams TM, Ragheh MM. Basically, the type (IV) system (T4SS) helps the transport of CagA proteins from gastric mucosal surface to endothelial cells for tyrosine phosphorylation and subsequent induction of immune response [181]. Conventional PPIs require 3-5 d to achieve maximal and steady-state gastric acid inhibition, whereas P-CABs increase the intragastric pH to nearly 7 within four hours[80]. HHS Vulnerability Disclosure, Help Adherence of H. pylori to the gastric epithelial cells induces the expression of cagA [177]. The outer membrane adhesin proteins like blood group antigen-binding adhesin (BabA), SabA, outer inflammatory protein (OipA), H. pylori outer membrane protein (OMP), and other proteins interact with the receptors found on the host epithelial cells. Trước đây 15 ngày em test HP bằng hơi thở cho kết quả âm tính và trước đây em khám nội ... Ung thư thực quản là nguyên nhân gây tử vong do ung thư đứng hàng thứ 6 trên toàn thế giới. [59] did not show any positive association between dupA and peptic ulcer disease. The result from the investigation showed that H. pylori HopQ-dependent interaction greatly facilitated the translocation and phosphorylation of CagA. Ví dụ về thuốc ức chế bơm proton bao gồm rabeprazole (Pariet), lansoprazole (Prevacid), omeprazole (Losec), pantoprazole (Protonix), dexlansoprazole và esomeprazole. Other outer membrane proteins (OMP) possessed by H. pylori include Helicobacter OMPQ (HopQ) and Helicobacter OMPZ (HopZ). It is most likely spread through water and food contaminated with poo. Suzuki S, Gotoda T, Kusano C, Iwatsuka K, Moriyama M. The Efficacy and Tolerability of a Triple Therapy Containing a Potassium-Competitive Acid Blocker Compared With a 7-Day PPI-Based Low-Dose Clarithromycin Triple Therapy. EPIYA D releases a higher amount of IL-8 [190]. Available from: Yang X, Zhang T, Zhang H, Sang S, Chen H, Zuo X. Temporal trend of gastric cancer burden along with its risk factors in China from 1990 to 2019, and projections until 2030: comparison with Japan, South Korea, and Mongolia. It has been proven to protect H. pylori from oxidant activities and oxidative stresses [219]. Bismuth-based H. pylori regimens are strongly recommended in China. Accordingly, recent research has focused on the optimal drug regimen in terms of dose, treatment duration, and minimal adverse events[68]. pylori resistance to antibiotics in China, Japan, and South Korea. An official website of the United States government. Hướng dẫn tại Hoa Kỳ và các quốc gia khác khuyến cáo rằng bệnh nhân cần dùng thuốc chống viêm lâu dài như aspirin, ibuprofen, naproxen và các loại thuốc tương tự điều trị viêm khớp và các tình trạng y tế khác nên được kiểm tra H. pylori và nếu bị nhiễm phải điều trị để loại bỏ nhiễm H. pylori. Other methods of treatments have also received recognition across the globe. Also, the development of H. pylori infections after the invasion depends on bacterial survival, virulence factors, and the host factors such as the immune system and environmental determinants [46–49]. Meta-analysis: is combination of tetracycline and amoxicillin suitable for Helicobacter pylori infection? The effects of varying acidity on Helicobacter pylori growth and the bactericidal efficacy of ampicillin. The formation of the biofilm helps to reduce its susceptibility to antibiotics, thus bringing about mutations that complicate bacterial eradication. H. pylori is present in more than half of the world’s population[3]. official website and that any information you provide is encrypted Several other studies are also available reporting a positive correlation between gastrointestinal diseases and H. pylori. The Toronto consensus for the treatment of, Chey WD, Leontiadis GI, Howden CW, Moss SF. Along with efficacious antibiotics, sufficient and continuous acid suppression is required for successful eradication[71]. [59] reported a positive association between vacA s1 and peptic ulcer disease. vacA s1b allele was detected in 8 strains (5 s1b/ml, 3 s1b/m2), while 18 (43.9%) of the isolates harboured the vacA s2/m2 allele. Significance of dormant forms of, Reshetnyak VI, Burnistrov AI, Maev IV (2021), Lerardi E, Losurdo G, Mileti A, Paolillo R, Giorgio F, Principi M, Di Leo A. The genetic population structure and analysis of H. pylori has recently been studied by Jiang et al. Để đảm bảo hiệu quả điều trị H. pylori, điều quan trọng là phải dùng tuân thủ đúng phác đồ điều trị, đủ thời gian quy định. Accessibility H. pylori use flagella-mediated motility for movement towards the stomach’s epithelial cells and to penetrate the mucus lining [9]. Several OMPs have been identified to contribute to the virulence of H. pylori. Helicobacter pylori strains vary cell shape and flagellum number to maintain robust motility in viscous environments. [87] is recommended. Invasive methods include endoscopic evaluation, histology, rapid urease test (RUT), and bacterial culture. Điều quan trọng là phải hoàn thành liệu trình điều trị của tất cả các loại thuốc để đảm bảo rằng vi khuẩn bị tiêu diệt. This strategy is markedly different from Japanese and South Korean guidelines, in which the first- and second-line regimens are divided. Sitafloxacin (STFX)-based triple therapy has been recommended as a third-line therapy in combination with AMX or MDZ[46]. and transmitted securely. H. pylori is a bacteria that can damage the stomach's protective lining. [199] showed that dupA is associated with an increased risk of duodenal ulcers. A recent investigation by El-Sayed et al. Non-invasive methods include urea breath test (UBT), stool antigen test (SAT), serology, and molecular diagnostic approaches [60]. It determines the quality of protein and is important in the evasion of oxidative stress. The babA2 gene encodes BabA. World Gastroenterology Organization Global Guideline. Creation and initial characterization of isogenic, Roesler BM, Costa SCB, Zeitune JMR (2011) Virulence factors of, Bridge DR, Merrell DS. OipA) has been established in several studies, although there is no clear information about the structure and the receptors of this adhesion protein OipA. H. pylori may also be spread through contaminated food or water. Both UBT and SAT have high sensitivities and specificities [73, 74]. It also causes the production of free radicals with implications on the outcome of several diseases. Other symptoms include excessive burping, bloating, weight loss, and heartburn [10]. Nickel uptake and utilization by microorganisms. OMV is a small, circular structure with an intact outer membrane expressed on the surface of H. pylori and other Gram-negative bacteria. For example, a study by Altobelli et al. The standard dose of a proton pump inhibitor (PPI) and 220 mg of bismuth are prescribed twice daily with the two antibiotics. Although all H. pylori strain harbour vacA, there is a variation in the degree of vacuolation activity of the encoded cytotoxins [156]. The role of bacterial membrane vesicles in the dissemination of antibiotic resistance and as promising carriers for therapeutic agent delivery. Ở Hoa Kỳ và các nước phát triển khác, nhiễm H. pylori là bất thường trong thời thơ ấu nhưng trở nên phổ biến hơn ở tuổi trưởng thành. Helicobacter pylori (H. pylori or, as it is sometimes termed, stomach bacteria) is a spiral-shaped gram-negative bacterium that can cause chronic inflammation of the inner lining of the stomach (gastritis) and in the duodenum (first part of the small bowel) in humans. Growth and morphological transformations of. The time above the MIC can reach 24 hours if 500 mg of AMX is dosed four times a day[70]. H. pylori treatment guidelines in China, Japan, and South Korea were revised according to new data. Animal assays revealed that L. reuteri 2892 . IL-8), Enhance bacterial growth and its resistance to antibiotics. CAM- and MDZ-containing regimens displayed high eradication rates of 88.8% and 88.9% in the intention-to-treat (ITT) analysis, and 94.9% and 96.9% in the per-protocol (PP) analysis, respectively. Hathroubi S, Servetas SL, Windham I, Merrell DS, Ottemann KM. In East Asia, CAM resistance of H. pylori has increased by > 15%. Of most notable importance are the BabA and SabA adhesins [107, 111–113]. Helicobacter pylori is a helix-shaped (classified as a curved rod, not spirochaete) Gram-negative bacterium about 3 μm long with a diameter of about 0.5 μm. Notably, molecular testing to detect CAM resistance is recommended as the initial treatment option. VA-DT showed a comparable H. pylori eradication rate without the need for CAM. However, the level of expression of cagA varies among H. pylori strains. The H. pylori eradication efficacy of regimens employing AMX and TET may not be inferior to other regimens[31]. Here we critically reflect on H. pylori infection and delineate what is currently known about the virulence and pathogenesis mechanisms of H. pylori. An overview of, Ricci V. Relationship between VacA toxin and host cell autophagy in, de Falco M, Lucariello A, Iaquinto S, Esposito V, Guerra G, De Luca A. Molecular mechanisms of. The morphology of H. pylori may also have a specific function on host–pathogen interaction. In a meta-analysis, Li et al[77] included randomized controlled studies in which both a PPI and AMX were administered four times daily. The resistance rates of H. pylori to AMX, TET, and FZD remain low in China at < 5%[29]. Sabbagh P, Javanian M, Koppolu V, Vasigala VR, Ebrahimpour S.

Primary antibiotic resistance in Helicobacter pylori in the Asia-Pacific region: a systematic review and meta-analysis. Pharmacologic aspects of eradication therapy for Helicobacter pylori Infection. Một số tác dụng phụ phổ biến gồm: Có tới 20 phần trăm bệnh nhân bị nhiễm H. pylori không được chữa khỏi sau khi hoàn thành liệu trình điều trị đầu tiên. Before Urease has been demonstrated as a virulence factor for some species like Proteus mirabilis, Staphylococcus saprophyticus, and H. pylori [93]. The advantages of the H. pylori regimens used in China, Japan, and South Korea need to be combined in future research. Vacuolation resulting from the activities of VacA protein can lead to multiple pathogenic effects on the host cell, such as vacuolation cytotoxicity and apoptosis [144–146]. More studies are needed to properly understand and characterize all the virulence factors and determine how they are linked to gastrointestinal diseases. Membrane topology of the NixA nickel transporter of, Wolfram L, Bauerfeind P. Conserved low-affinity nickel-binding amino acids are essential for the function of the nickel permease NixA of. Approximately 8.5 million H. pylori-positive patients received eradication regimens from 2013 to 2019[34]. The external is primarily produced during the lysis of other bacterial cells and functions at a pH of 5.0–8.0, while the internal function is at pH of 2.5–6.5 [37, 140]. Polyzos SA, Zeglinas C, Artemaki F, Doulberis M, Kazakos E, Katsinelos P, et al. But for others, the bacteria can cause a variety of digestive disorders . For the treatment of most H. pylori diseases, triple antibiotic therapy consisting of proton-pump inhibitor (PPI) and two antibiotics (usually amoxicillin and metronidazole/clarithromycin) have been used as a conventional method of treatment. Yu XJ, Yang X, Feng L, Wang LL, Dong QJ. Marcus EA, Inatomi N, Nagami GT, Sachs G, Scott DR. HpHtrA mutant strain has been shown to be more susceptible to induced stress [211]. The OMP family two genes encode for OMPs of unknown function. This mechanism helps H. pylori to persist in the environment with influence on the host cell immunity. The latter is one of the most prevalent malignancies and currently the fourth major cause of cancer-related deaths globally. de Francesco V, Zullo A, Perna F, Giorgio F, Hassan C, Vannella L, Lerardi E. Ogata SK, Kawakami E, Patrício FR, Pedroso MZ, Santos AM. Notably, a modified BQT containing AMX and MDZ was demonstrated to be effective (> 90%) in MDZ-resistant H. pylori strains. CAM resistance is a strong contributor to H. pylori eradication failure after first-line treatment[42]. It is made up of periplasmic proteins, toxins, outer membrane proteins (OMPs), and lipids. The immunomodulator VacA promotes immune tolerance and persistent. East Asian countries have high rates of gastric cancer (age-standardized incidence rate: 20-30 per 100000). Evidence is also available reporting spiral to coccoid transition as a unique tactic H. pylori uses to survive in the host’s gastrointestinal tract (GIT). All rights reserved. H. pylori can induce several genetic alterations, express numerous virulence factors, and trigger diverse adaptive mechanisms during its adherence and colonization. However, multiple amplification is usually needed for all the known genes and their variants, which can be time-consuming and require many funds. Việc này thường đòi hỏi bệnh nhân phải dùng thuốc ức chế bơm proton 14 ngày và hai loại kháng sinh. [207] revealed that dupA-positive H. pylori infection was associated with a two-fold chance of developing gastritis. In H. pylori infection, apoptosis is increased, especially in the gastric gland of the host cells [155]. FOIA The novel P-CAB vonoprazan (VPZ) exerts a rapid and sustained suppressive effect on gastric acid for optimal H. pylori treatment[37]. According to the South Korean nationwide registry database, the prescription rate of the classic BQT as a first-line therapy is currently low (2.63%)[57]. and Sutton P (2018) Superoxide dismutase from, Shibayama K, Wachino JI, Arakawa Y, Saidijam M, Rutherford NG, Henderson PJ. In South Korea, tailored eradication can be used as a first-line H. pylori treatment option based on the presence of a point mutation. Normally, a complex mechanism keeps cell proliferation and cell death in place to maintain a balance. Chen et al[26] performed a comparative study between the classic BQT and a modified one containing AMX and MDZ as a rescue H. pylori therapy. RUT detects the presence of urea production, although factors like bacterial load and the presence of other urease producing pathogens can result in a wrong diagnosis [67]. Association between, Sato Y, Yoneyama O, Azumaya M, Takeuchi M, Sasaki SY, Yokoyama J, et al. Diagnostic tests Invasive diagnosis of H pylori infection is by biopsy specimens obtained at gastroduodenoscopy for a rapid urease test and for histology; microbiological culture these days is limited to research centres.

Most people pick up the infection as children. The sequential therapy consists of a PPI and 1 g of AMX twice daily for 5 d, followed by the PPI, 500 mg of CAM, and 500 mg of MDZ twice daily for 5 d. Concomitant and sequential therapy resulted in good H. pylori eradication rates of 94.2% and 91.7% in a modified ITT analysis, and 95.6% and 91.4% in the PP analysis, respectively[50]. Hansen G, Hilgenfeld R. Architecture and regulation of HtrA-family proteins involved in protein quality control and stress response. Heterogeneity in levels of vacuolating cytotoxin gene (vacA) transcription among, Rhead JL, Letley DP, Mohammadi M, Hussein N, Mohagheghi MA, Hosseini ME, Atherton JC. The recommended AMX and CAM doses are 750 and 200 mg twice daily, respectively. On the other hand, it remains to be completely understood why most individuals infected with H. pylori remain asymptomatic while some develop severe gastric diseases. Thus, extending the treatment duration of VA-DT to 14 d may be a promising alternative H. pylori treatment. PPIs may be replaced by VPZ due to its rapid and strong acid suppression. Online registry for nationwide database of Helicobacter pylori eradication in Korea: Correlation of antibiotic use density with eradication success.

Tóm lại, hầu hết mọi người được chữa khỏi sau khi kết thúc hai tuần dùng thuốc. 15/41 (36.6%) were carrying vacA s1 allele (vacA sla/m1 and vacA slam2). Lu H, Zhang W, Graham DY. The transformation of the bacterium from the spiral form to the coccoid form occurs under adverse environmental conditions. It is more common in developing countries. H. pylori phosphorylation site is made up of Glu-Pro-Ile-Tyr-Ala (EPIYA) sequence repeat (EPIYA motif) or other closely related sequences [183] located at the N-terminal region [184, 185] and a C-terminal tail. Madrid, Spain Correspondence ABSTRACT According to the investigation, the presence of htrA-171 polymorphism resulted in a higher rate of gastric cancer. Strains carrying vacA s2/m2 do not have any cytotoxic activity; s1/m2 exhibit intermediate cytotoxic activity, while s1a/m1 exhibit more cytotoxic activity. [114] showed that OipA was highly significantly associated with gastroduodenitis, thus suggesting that they could be a great biomarker in predicting mucous progress in patients with chronic gastritis. In the DT group, drug-related adverse events occurred less frequently compared to the current mainstream therapy recommended by guidelines (12.9% vs 28.0%, P < 0.001). Jones KR, Joo YM, Jang S, Yoo YJ, Lee HS, Chung IS, Cha JH. However, the vast majority of the infected population does not develop symptoms related to H. pylori infection [6]. the contents by NLM or the National Institutes of Health. They are often referred to as the spiral viable culturable form (SVCF), whereas the coccoid form is viable but non-culturable (CVNCF). Untreated, an H.pylori infection can lead to complications. and transmitted securely. Qiao C, Li Y, Liu J, Ji C, Qu J, Hu J, Ji R, Wan M, Lin B, Lin M, Qi Q, Zuo X. Clarithromycin versus furazolidone for naïve Helicobacter pylori infected patients in a high clarithromycin resistance area. The bacterium 385 IARC MONOGRAPHS - 100B displays remarkable motility in viscous solutions, and the flagella play a central role in this motility (Hazell et al., 1986; Suerbaum et al., 1993). Seven-day VPZ, AMX, and MDZ triple therapy can be a strong candidate as an empirical H. pylori regimen. Trong trường hợp đó, bác sĩ sẽ kê đơn phác đồ điều trị thứ hai. However, there is a high risk of contamination of the sample by viruses such as human immunodeficiency virus (HIV) and hepatitis C virus (HCV) [64, 65]. HopQ, another important outer membrane porins, is active in the transportation of virulence substances extruded by CagA into the host cell [120], possibly through the T4SS system [121, 122], and Hom enhances secretion of IL-8 and other inflammatory factors as well as adhesion to host cells [90]. Variation within the EPIYA region also results in variation in the amount of ILs produced. In Japan, H. pylori treatment success has increased since VPZ was launched. [77] using the whole-genome-based approach. Comparison of the diagnostic accuracy of five different stool antigen tests for the diagnosis of, Yang BL, Yeh C, Kwong WG, Lee SD. flaA mutant strain of H. pylori cannot produce flagella at all, while that which is deficient in flaB might produce flagella [97, 98].
