Provenance and peer review: Invited article; Externally peer reviewed. Helicobacter pylori (H. pylori) is a corkscrew-shaped bacteria that was identified in 1982 as a principal cause of stomach ulcers and chronic gastritis, conditions which were formerly believed to be caused by stress and poor diet. The pathogen infects about 50% of the world population, and currently, no treatment ensures its total elimination. 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. Xét nghiệm máu - Xét nghiệm máu có thể phát hiện các kháng thể mà hệ thống miễn dịch của cơ thể phát triển để đáp ứng với vi khuẩn H. pylori . Here, we aimed to compare the efficacy and cost-effectiveness of bismuth-based quadruple therapy versus metronidazole-intensified triple therapy with increased the . the contents by NLM or the National Institutes of Health. H. pylori produce high catalase content as one of its highly expressed proteins and are more resistant to inhibition by cyanide or amino triazole compared to catalase from other species [218]. These are widely performed on gastric juice, saliva, urine, and stool specimens. Clustering and redistribution of late endocytic compartments in response to, Kern B, Jain U, Utsch C, Otto A, Busch B, Jiménez-Soto L, Haas R. Characterization of, Bernard MD, Moschioni M, Habermann A, Griffiths G, Montecucco C. Cell vacuolization induced by, Cover TL, Krishna US, Israel DA, Peek RM. UBT and SAT are the most commonly used non-invasive tests, and they are also the best methods to diagnose H. pylori infection [10, 59, 62, 63]. 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]. H. pylori adhesins further interact with the host cell receptors leading to successful colonization and persistent infection. Untreated, an H.pylori infection can lead to complications. Once H. pylori effector protein (CagA) reaches the host cell, they interact with a variety of host SH2 domain where tyrosine phosphorylation occurs. In addition, several environmental factors such as smoking, excessive intake of alcohol, presence of carcinogens, and diet play a crucial role in the pathogenesis of H. pylori [43–45]. This flagellum also protects the bacterium from the gastric environment [10]. Primary Antibiotic Resistance of Helicobacter pylori in China. The colonization with H. pylori is not a disease in itself. The resistance rate of H. pylori to LVFX is relatively high at approximately 15%[19]. In 1989, PPI-AMX dual therapy (DT) was first used to eradicate H. pylori[73]. 8600 Rockville Pike Another important virulence factor is the cytotoxin-associated gene product (CagA). Type III and IV systems allow penetration of the plasma membrane and delivery of bacterial molecules directly into the cytoplasm of target cells. A high dosage (1500 mg/d) of MDZ for 14 d can overcome H. pylori resistance[25]. Also, chronic mouse model infection showed that there was downregulation of hCEACAM and -6 receptors on neutrophils. H. pylori adhesins bind to mucins in the gastric mucus and receptors on the surface of the gastric mucosa. Also, inside the cytoplasm and periplasm, and sometimes on the surface, they play roles in various pathological processes such as inflammation, apoptosis inhibition, as well as tumour formation resulting from mutagenesis. The filament is composed of several types of protein subunits, such as FlaA and FlaB [10, 92–94]. A decrease in the motility and adhesion capacity of a flaB deficient strain has been demonstrated [11]. They are essential in the adhesion of the bacteria to the epithelial cell of the host [76] and can enhance cag-pathogenicity island stimulation of pro-inflammatory immune response and induce signalling in the host cell [76, 109]. The overall seroprevalence rate of H. pylori infection is 44.2% in China, 37.6%-43.2% in Japan, and 51.0% in South Korea[4-6]. HHS Vulnerability Disclosure, Help Family 1 is composed of the hop and hor genes. This suggests a reversion of the inoculated CVNCF to an SVCF following gastric infection. Helicobacter pylori normally infect the stomachs of children where, if undetected, they can stay forever. This mechanism helps H. pylori to persist in the environment with influence on the host cell immunity. The pathogen produces several effector proteins/toxins responsible for damage to the host tissues. Before Interestingly, this bacterium can navigate between two different shapes depending on the physiological activity required, such as survival during adverse environmental conditions (temperature or pH shifts, long intervals between meals, and antibiotic therapy) [3]. A recent nationwide study reported H. pylori resistance rates to CAM, MDZ, and LVFX of 17.8%, 29.5%, and 37.0%, respectively[17]. Graham DY, Lu H, Shiotani A. 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. As chloride ions from the gastric environment flow through this channel into the late endosome, accumulation leads to an increase in the chloride concentration, which in turn enhances V-ATPase proton pump activity and a decrease in the intracellular pH. H. pylori can also form biofilms. As an alternative, molecular methods for detecting CAM resistance are available for tailored H. pylori eradication in South Korea[60]. Hoy B, Löwer M, Weydig C, Carra G, Tegtmeyer N, Geppert T, Wessler S. Elmi A, Nasher F, Jagatia H, Gundogdu O, Bajaj-Elliott M, Wren B, Dorrell N. Campylobacter jejuni outer membrane vesicle-associated proteolytic activity promotes bacterial invasion by mediating cleavage of intestinal epithelial cell E-cadherin and occludin. For example, Alam et al. These virulence pathways could be leveraged for therapeutic targets. It binds to corresponding receptors on epithelial cells such as receptor-like protein tyrosine phosphatase alpha and beta (RPTP-α, RPTP-β), density lipoprotein receptor-related protein-1 (LRP-1), and sphingomyelin [145, 150]. The .gov means it’s official. Helicobacter pylori is strongly linked to peptic ulcer disease and is classified as a group 1 carcinogen by the World health Organization's international Agency for Research on cancer. 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]. However, ever since the discovery of dupA in 2005, there have been several published contradictory results on its pathogenicity role [198, 203–206]. In contrast, the Src kinase binds to the A and the B segment [189], which in turn inhibit SFK activity. Bismuth-containing quadruple therapy for Helicobacter pylori: lessons from China. Vi khuẩn HP có lây không và lây qua đường nào? Zhang W, Chen Q, Liang X, Liu W, Xiao S, Graham DY, Lu H. Bismuth, lansoprazole, amoxicillin and metronidazole or clarithromycin as first-line Helicobacter pylori therapy. 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.

Gastric cancer: epidemiology, risk factors, classification, genomic characteristics and treatment strategies. However, it is a condition that could affect the risk of developing various clinical disorders [7, 52]. H. pylori is a bacteria that can damage the stomach's protective lining. About 40% of people in the UK have Helicobacter pylori in their stomach so it is very common and in the approximately 8 to 9 out of 10 people who have it, does not cause any problems. This can skew the response of T cells towards Tregs. EPIYA D releases a higher amount of IL-8 [190]. 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. Several other effector proteins play a crucial role in the pathogenesis of H. pylori. However, susceptibility-guided therapy is time-consuming and requires specific expertise in clinical practice[59]. Helicobacter pylori diagnosis and therapy in the era of antimicrobial stewardship. The recommended eradication regimens for H. pylori include AMX and CAM, AMX and MDZ, AMX and LVFX, AMX and FZD, AMX and TET, MDZ and TET, and FZD and TET (Table ​(Table1).1). Also, during prolonged in vitro culture or even antibiotic treatment, the coccoid shapes could appear [4]. Backert S, Selbach M. Tyrosine-phosphorylated bacterial effector proteins: the enemies within. Type one is made up of the outer membrane porins (Hop), Hop-related proteins (Hor), type 2 comprises of the Hof, and type 3 comprise the H. pylori outer membrane proteins (Hom). Tại Bệnh viện Đa khoa Quốc tế Vinmec sử dụng đồng vị carbon 13C trong test hơi thở chẩn đoán vi khuẩn H. pylori với loại máy ưu việt hàng đầu có gắn 02 túi khí, vừa cho giá trị chẩn đoán rất cao (> 95%) vừa đảm bảo an toàn cho người bệnh. This protease is important for the pathogen to survive extreme temperature, pH, and salt concentration [216] and could be a target for anti-H pylori therapy. H. pylori can be demonstrated in tissue by Gram stain, Giemsa stain, haematoxylin-eosin stain, Warthin-Starry silver stain, acridine orange stain, and phase-contrast microscopy. Hanafiah A, Lopes BS (2020) Genetic diversity and virulence characteristics of, Salama NR. Bismuth has long been used to treat peptic ulcer disease, dyspepsia, parasite infections, and infectious diarrhea[22]. Articles | Volume 6, ISSUE 3, P185-194, March 2022. Low MDZ resistance against H. pylori is thought to be correlated with antibiotic consumption in the community. Qiao et al[28] reported that an FZD-based BQT showed a similar first-line H. pylori eradication rate in PP analysis to a CAM-based BQT (95.8% vs 93.4%). Clausen T, Kaiser M, Huber R, Ehrmann M. HTRA proteases: regulated proteolysis in protein quality control. The creation of vacuoles on a host cell is known as vacuolation. Watari J, Chen N, Amenta PS, Fukui H, Oshima T, Tomita T, et al. Thereafter, the organism crosses the acidic environment to areas with suitable conditions. The genotype of the SVCF and CVNCF strains (cagA + vacA + s1a m1 i1) that survived in milk was the same as the inoculated one, suggesting the conversion of the SVCF to a CVNCF. The number of flagella has been reported to increase the speed of bacterial cells during movement [96]. Choi YI, Chung JW, Park DK, Kim KO, Kwon KA, Kim YJ, Seo JY. However, VPZ was superior to the PPI-based triple regimen for CAM-resistant H. pylori strains (73.2%-87.5% vs 40.0%-53.8%)[41]. Almost half of the incident cases and deaths occur in East Asia. Some of the major effector proteins/toxins released by H. pylori include blood group antigen-binding adhesion (BabA), outer inflammatory protein (OipA), outer membrane protein (OMP), outer membrane vesicles (OMV), vacuolating cytotoxins (VacA), a cytotoxin-associated gene product (CagA), high-temperature requirement A (HtrA), neutrophil-activating protein A (NepA), and sialic acid-binding adhesins (SabA) [37]. New helicobacter species are now regularly being discovered. In addition, studies have shown that the H. pylori strain display different degrees of virulence that determine their pathogenicity and potential disease progression. Benoit SL, Maier RJ. Sau khi kết thúc liệu trình tiệt trừ H. pylori, bác sĩ sẽ cho xét nghiệm lại để đảm bảo rằng tình trạng nhiễm trùng đã được giải quyết. Furthermore, the PMNs greatly increased the expression of pro-inflammatory chemokines MIP-1-alpha. Strains carrying vacA s2/m2 do not have any cytotoxic activity; s1/m2 exhibit intermediate cytotoxic activity, while s1a/m1 exhibit more cytotoxic activity. Purification and characterization of the vacuolating toxin from. H.pylori can cause stomach inflammation (gastritis) and more serious conditions such as stomach ulcers and stomach cancer. Metal limitation and toxicity at the interface between host and pathogen. Polymorphism in the, Figura N, Trabalzini L, Mini R, Bernardini G, Scaloni A, Talamo F, Santucci A. Inactivation of.

The mechanism of action is different from that of PPIs. Moreover, vacuoles induced by VacA contain markers typically found in membranes of late endosomes [168–171]. [130] also portray the survival of H. pylori in the adverse condition through a transformation from spiral to coccoid form. However, there is an established relationship between its expression and the activities of cagA, as the expression of the oipA genes determines the expression of cagA [117, 118]. Li C, Shi Y, Suo B, Tian X, Zhou L, Song Z. PPI-amoxicillin dual therapy four times daily is superior to guidelines recommended regimens in the Helicobacter pylori eradication therapy within Asia: A systematic review and meta-analysis. Accordingly, the number of CAM-resistant H. pylori strains has increased rapidly in many countries over the past decade[14]. (2014) Association among, Gomes LI, et al. Many factors, however, influence choices in the method of diagnosis: availability of diagnostic instruments/materials, sampling population, and competency and experience of the physicians/clinicians, among others [59]. In the present review, we discussed what is currently known about the virulence and pathogenesis mechanisms of H. pylori. Pereira WN, Ferraz MA, Zabaglia LM, de Labio RW, Orcini WA, Bianchi Ximenez JP, et al. However, with the recent surge in antibiotic resistance, triple therapy has become less effective.

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 transmission mode is associated with contaminated food and water [6, 29–31]. Sadly, the resistance of H. pylori to antibiotics treatment is rising daily, making treatment of H. pylori difficult. [59] reported a positive association between vacA s1 and peptic ulcer disease. Nishizawa T, Suzuki H. Mechanisms of Helicobacter pylori antibiotic resistance and molecular testing. There was an observed decrease in the microbial load between 1 and 10 days. Graham DY, Dore MP, Lu H. Understanding treatment guidelines with bismuth and non-bismuth quadruple Helicobacter pylori eradication therapies. They are also found to be expressed in the outer membrane vesicles of Vibrio cholera, Chlamydia muridarum, or Borrelia burgdorferi [212, 213]. It also causes the production of free radicals with implications on the outcome of several diseases. If you have H. pylori infection, carbon is released when the solution comes in contact with H. pylori in your stomach. The Urel-channel closes whenever the gastric environment is at a neutral pH (7.0) and opens when there is a change in the acidic level of the stomach [6, 11]. Several OMPs have been identified to contribute to the virulence of H. pylori.

OMV is a small, circular structure with an intact outer membrane expressed on the surface of H. pylori and other Gram-negative bacteria. Zou et al[78] reported that 14-d DT had a higher H. pylori eradication rate than 10-d DT in ITT (89.7% vs 78.4%, P = 0.039) and PP (92.9% vs 80.0%, P = 0.014) analyses. HpHtrA mutant strain has been shown to be more susceptible to induced stress [211]. Helicobacter pylori is an organism associated with ulcer disease and gastric cancer. As a first-line H. pylori treatment, administering high-dose DT resulted in a higher eradication rate than other regimens in ITT analysis (89.8% vs 84.2%, P = 0.04) and PP analysis (92.9% vs 88.3%, P = 0.06). In H. pylori–infected stomachs, gastric atrophy and intestinal metaplasia are linked to gastric cancer development[2]. Zarzecka U, Modrak-Wójcik A, Figaj D, Apanowicz M, Lesner A, Bzowska A, Skorko-Glonek J. Helicobacter pylori (H. pylori) are bacteria, a type of germ, which lives in the sticky mucus that lines the stomach. In China, adding bismuth to all H. pylori regimens is recommended as the empirical first-line treatment. Richter C, Mukherjee O, Ermert D, Singh B, Su YC, Agarwal V, Riesbeck K.

The VacA helps in the disruption of the epithelial barrier. It can infect the lining of the stomach and duodenum (the first part of the intestine). Understanding how this organism uses its shape to its advantage and how it influences clinical outcomes will be crucial as it will help properly decipher how it can survive and establish infection. Other important virulence factors in H. pylori, Activate signalling pathways (e.g. [37] showed that LacdiNAc-specific adhesin (LabA) facilitates H. pylori adherence to the gastric epithelium. As a first-line treatment, high-dose, high-frequency DT was effective and safe for treating H. pylori infections in elderly patients and those with multiple comorbidities[79]. moc.revan@dmhjohc, Department of Pathology, Soonchunhyang University Hospital, Seoul 04401, South Korea.

Nhất là với những trường hợp người có tiền sử về bệnh liên quan đến tiêu hóa hoặc có người thân trong gia đình từng nhiễm vi khuẩn HP. Colonization and establishment of diseases and infection by H. pylori depend on four major stages: (1) adaptation to the acidic environment of the gastric mucosa, (2) the movement towards the epithelial cells using the flagella, (3) penetration of the epithelial cell barrier and attachment to specific receptors, and (4) tissue damage and other detrimental health effects. The binding of H. pylori to gastric epithelial cells, colonization, and even biofilm formation in H. pylori are also mediated by adherence-associated lipoprotein A and B (AlpA/AlpB). Since H. pylori treatment for chronic gastritis was approved by the Japanese national health insurance system in 2013, prescriptions for eradication therapy have markedly increased. Therefore, to successfully colonize the host and establish infection, H. pylori must be able to survive the acidic stomach, attach to the host cells, and release damaging tissue toxins.
