Chukwudile B, Pan D, Silva L, Gogoi M, Al-Oraibi A, Bird P, George N, Thompson HA, Baggaley RF, Hargreaves S, Pareek M, Nellums LB. Antimicrobial resistance among migrants in Europe: a systematic review and meta-analysis - update from 2017 to 2023. EClinicalMedicine 2024; 75:102801. [PMID: 39296945 PMCID: PMC11408055 DOI: 10.1016/j.eclinm.2024.102801] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/30/2024] [Revised: 07/17/2024] [Accepted: 08/12/2024] [Indexed: 09/21/2024] Open
Abstract
Background Antimicrobial resistance (AMR) is a critical global health concern. A previous systematic review showed that migrants in Europe are at increased risk of AMR. Since the COVID-19 pandemic there have been rapid changes in patterns of antibiotic use, AMR, and migration. We aimed to present an updated evidence synthesis on the current distribution of AMR among migrants in Europe. Methods We carried out a systematic review and meta-analysis in accordance with PRISMA guidelines (PROSPERO ID: CRD42022343263). We searched databases (MEDLINE, Embase, PubMed and Scopus) from 18 January 2017 until 18 January 2023 to identify primary data from observational studies reporting any laboratory-confirmed AMR among migrants in the European Economic Area (EEA) and European Union-15 (EU-15) countries using over 7 key search terms for migrants and over 70 terms for AMR and countries in Europe. Outcomes were infection with, or colonisation of AMR bacteria. Methodological quality was assessed using Joanna Briggs Institute Critical Appraisal Checklist for Observational Studies. We meta-analysed the pooled-prevalence of infection and/or colonisation of AMR organisms. Findings Among 630 articles, 21 observational studies met the inclusion criteria and were included in this review. The pooled prevalence for any detected AMR was 28.0% (95% CI 18.0%-41.0%, I 2 = 100%) compared to a 25.4% seen in the previous review; gram-negative bacteria 31.0% (95% CI 20.0%-44.0%, I 2 = 100%), and methicillin-resistant staphylococcus aureus 10.0% (95% CI 5.0%-16.0%, I 2 = 99%). Drug-resistant bacteria were more prevalent in community settings in large migrant populations (pooled prevalence: 41.0%, 95% CI 24.0%-60.0%, I 2 = 99%) than in hospitals (21.0%, 95% CI 12.0%-32.0%, I 2 = 99%). AMR estimates in 'other' migrants were 32.0%, (95% CI 12.0%-57.0%, I 2 = 100%) and 28.0% (95% CI 18.0%-38.0%, I 2 = 100%) in forced migrants. No firm evidence of AMR acquisition with arrival time or length of stay in the host country was found. Interpretation Studies investigating AMR in migrants are highly heterogenous. However, since the COVID-19 pandemic, migrants may be at higher risk of acquiring resistant bacteria, particularly gram-negative bacteria, within community settings such as refugee camps and detention centres in Europe. Our study highlights the importance of infrastructure and hygiene measures within these settings, to mitigate transmission of resistant pathogens. Policy-makers should screen for AMR in migrants prior to departure from countries of origin, where feasible, and upon arrival to a new country to ensure optimal health screening, infection control and effective treatment. Funding There was no funding source for this study.

Antimicrobial susceptibility of clinical Helicobacter pylori isolates and its eradication by standard triple therapy: a study in west central region of Colombia. Microbiol Spectr 2024; 12:e0040124. [PMID: 38916348 PMCID: PMC11302661 DOI: 10.1128/spectrum.00401-24] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/19/2024] [Accepted: 04/26/2024] [Indexed: 06/26/2024] Open
Abstract
The aim of the present study was first to isolate Helicobacter pylori from gastric biopsy specimens and to test their antibiotic susceptibility. Second, it was to evaluate the efficacy of the standard triple therapy from patients of the west central region of Colombia. H. pylori positive patients received standard triple therapy with proton pump inhibitor (PPI) (40 mg b.i.d.), clarithromycin (500 mg b.i.d.), and amoxicillin (1 g b.i.d.) for 14 days. Thereafter, antibiotic susceptibility of the isolates was assessed by E-Test. From 94 patients enrolled, 67 were positive for H. pylori by histology or culture. Overall resistance to metronidazole, levofloxacin, rifampicin, clarithromycin, and amoxicillin was 81%, 26.2%, 23.9%, 19%, and 9.5%, respectively. No resistance was found for tetracycline. A total of 54 patients received standard triple therapy, 48 attended follow-ups testing, and of them, 30 had resistance test reports. Overall eradication rate was 81.2%. Second-line treatment was given to eight patients, four of whom were followed up with a 13C urea breath test (UBT) and remained positive for H. pylori. Eradication was significantly higher in patients with clarithromycin susceptible than in resistant strains (95.6% vs 42.8% P = 0.001). The updated percentages of resistance to clarithromycin in this geographical area had increased, so this value must be considered when choosing the treatment regimen.IMPORTANCEAntibiotic resistance in Helicobacter pylori has increased worldwide, as has resistance to multiple antimicrobials (MDRs), which seriously hampers the successful eradication of the infection. The ideal success rate in eradicating H. pylori infection (≥90%) was not achieved in this study (81.2%). This is the first time that MDR is reported (14.3%) in the region; the resistance to clarithromycin increased over time (3.8%-19%), and levofloxacin (26.2%) and rifampicin (23%) resistant isolates were detected for the first time. With these results, strain susceptibility testing is increasingly important, and the selection of treatment regimen should be based on local antibiotic resistance patterns.

Abstract
BACKGROUND Helicobacter pylori eradication failure influences its antibiotic resistance. AIMS This study aimed to evaluate the effect of previous treatment failures on it, including the changes in the antibiotic resistance rates, minimal inhibitory concentration (MIC) distributions, and resistance patterns. MATERIALS AND METHODS This single-center retrospective study included 860 primary isolates and 247 secondary isolates. Antibiotic susceptibility testing was performed for amoxicillin, metronidazole, clarithromycin, levofloxacin, furazolidone, tetracycline, and rifampicin. The demographic data and detailed regimens were collected. RESULTS The primary resistance rates to amoxicillin, metronidazole, clarithromycin, levofloxacin, tetracycline, rifampin, and furazolidone were 5.93%, 83.84%, 28.82%, 26.28%, 0.35%, 1.16%, and 0%, while secondary were 25.10%, 92.31%, 79.76%, 63.16%, 1.06%, 3.19%, and 0%, respectively. The resistance rates to amoxicillin, metronidazole, clarithromycin, and levofloxacin increased significantly with the number of treatment failures accumulated, and showed a linear trend. The proportion of primary and secondary multidrug-resistant (MDR) isolates were 17.79% and 63.16%, respectively. The MIC values of amoxicillin, clarithromycin, and levofloxacin were elevated significantly with medication courses increased. CONCLUSION The prevalence of amoxicillin, clarithromycin, levofloxacin, and metronidazole resistance would increase rapidly following first-line treatment failure, as well as the MIC values of them. Clinicians should pay great attention to the first-line treatment to cure H. pylori infection successfully.

Abstract
Helicobacter pylori has been reported as a health problem worldwide, affecting a sizable portion of people. Peptic ulcers, gastric cancer, and various extra gastric conditions are associated with this bacterium. The rampant overprescribing of antibiotics has led to the emergence of H. pylori strains resistant to multiple antibiotics, causing a decline in the effectiveness of current treatments. Recently, there has been growing interest in researching alternative treatment options for H. pylori infections that do not respond to initial therapy. Rifabutin, a rifamycin derivative initially designed for tuberculosis treatment and preventing Mycobacterium avium complex infection, has gained attention as a potential rescue medication. It has shown efficacy against H. pylori and the potential to eradicate the bacterium when combined with other antibiotics. This systematic review article focuses on using rifabutin-based regimens as a treatment option after initial treatments have failed. The authors screened literature published in the last five years, between 2017 and 2022, across various search engines and closely examined relevant studies following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) criteria. The search covered a variety of electronic databases and focused on H. pylori gastritis, rifabutin-based treatment plans, and in vivo investigations in healthy individuals. The comprehensive review provides convincing evidence that rifabutin-based regimens are effective rescue treatments for H. pylori infections. Multiple studies in various areas consistently demonstrated high eradication rates, ranging from 70% to 90%, when rifabutin-containing regimens were used. The analysis found that only a tiny percentage of H. pylori strains (1%) were resistant to rifabutin therapy, further supporting the viability of Rifabutin as an alternative when other antibiotics failed to eradicate H. pylori. The cost of Rifabutin is a significant factor that may limit its accessibility, particularly in resource-constrained settings where H. pylori infection is common. Moreover, the potential side effects of Rifabutin, such as hematological problems, rashes, and digestive issues, need to be considered. However, these side effects are typically manageable and can be reduced by combining Rifabutin with other antibiotics. In conclusion, this systematic review provides evidence supporting the effectiveness of regimens derived from Rifabutin in eliminating H. pylori infections after initial therapy failure. Due to the observation that Rifabutin effectively eradicates resistant H. pylori infections, it can be considered a suitable choice for rescue therapy. Rifabutin-containing regimens should be reserved as fourth- or later-line therapy options, considering economic factors, the risk of microbial resistance, potential side effects, and the availability of alternative medications. Future research should focus on optimizing rifabutin-based regimens and investigating combination therapies that have better H. pylori eradication rates while also addressing the problem of resistant strains.

Abstract
Introduction: Helicobacter pylori is an important medical pathogen present in more than half of the world’s population. Various treatment regimen are in use for the eradication of H. pylori, but due to the emergence of antibiotic resistance, its management is a big issue for clinicians. Methods: In this study all suspected cases that had visited District Headquarters Hospital Kohat were considered for screening of H. pylori infections. Preliminary information about their age, gender, general health conditions, occupation, etc. was taken for consideration. After recording initial signs and symptoms, samples were considered for H. pylori detection using stool antigen test and endoscopy. Fourteen-day proton pump inhibitor base triple and quadruple therapy were administered to each patient. Results: In total (n = 178), there were high numbers of positivity in patients aged below 30 years (82; 46.06%), most of whom belonged to rural areas. Conclusion: This study concludes that there were high numbers of positive patients aged below 30 years, and according to this study MEL (Metronidazole + Esomeprazole + Levofloxacin) is the most effective treatment regimen for the eradication of H. pylori.

Abstract
When several Helicobacter pylori eradication treatments fail, guidelines recommend a cultured guided approach; however, culture is not widely available. Therefore, a rifabutin based regimen could be the best solution. Rifabutin indeed shows a low rate of antibiotic resistance. Rifabutin is generally used in combination with amoxicillin in a triple therapy, with eradication rates about 80% in third-line regimens. The ideal duration of this therapy should range between 10 and 12 d. Combinations with antibiotics other than amoxicillin have demonstrated even better results, such as vonoprazan, which is a type of novel acid suppressor drug. Finally, a new formulation of triple therapy in a single capsule is under investigation, which is a field that deserves further investigation. Some notes of caution about rifabutin should be mentioned. This drug is used to treat tuberculosis or atypical mycobacteria; therefore, before starting a rifabutin-based eradication regimen, Mycobacterium tuberculosis infection should be thoroughly tested, since its use could promote the development of antibiotic resistance, thus affecting its effectiveness against Koch’s bacillus. Additionally, some serious side effects must be evaluated before starting any rifabutin-based therapy. Adverse effects include fever, nausea, vomiting and bone marrow suppression. For this reason, full blood count surveillance is required.

Abstract
Helicobacter pylori (H. pylori) resistance to antibiotics has increased worldwide in recent decades, especially to clarithromycin. As a result, the World Health Organization (WHO) identified clarithromycin-resistant H. pylori as a "high priority" pathogen in 2017. As international guidelines recommend empirical therapy as first-line treatment, it is crucial to know local resistance rates and history of antibiotic use to determine the most appropriate first-line antibiotic treatment. Italy is one of the European countries with the highest prevalence of H. pylori infection and the highest percentage of antibiotic-resistant H. pylori. The aim of this review is to summarize all data on H. pylori antibiotic resistance in Italy in order to quantify the current rate and determine the most effective therapeutic approach. The study confirms an elevated level of resistance to clarithromycin, metronidazole, and levofloxacin in Italy. In addition, our results show a satisfactory eradication rate for a bismuth-based regimen when used as first- or second-line treatment. Naive patients are also successfully treated with clarithromycin-based quadruple therapies. Considering the good results of bismuth-based therapy as recovery therapy, this argues for the potential use of clarithromycin quadruple therapy as a first-line treatment.

Abstract
BACKGROUND AND AIM Most consensuses recommend culture-guided therapy as third-line Helicobacter pylori treatment. This study aimed to investigate the efficacies of culture-guided therapy and empirical therapy with high-dose proton pump inhibitor (PPI) in the H. pylori third-line treatment. METHODS Between August 2012 and October 2021, H. pylori-infected patients with at least two failed eradication attempts received anti-H. pylori therapy according to the results of antimicrobial sensitivity tests plus high-dose rabeprazole and/or bismuth. They were categorized into three groups: patients who had positive results of culture with equal to or more than three susceptible antibiotics were treated by culture-guided non-bismuth quadruple therapy, patients who had positive results of culture with one or two susceptible antibiotics were treated by culture-guided bismuth-containing therapy, and patients who had a negative result of culture were treated by an empirical therapy with high-dose rabeprazole plus amoxicillin, tetracycline and levofloxacin. A post-treatment assessment was conducted at week 8. RESULTS We recruited 126 patients. The eradication rates of culture-guided non-bismuth quadruple therapy (n = 50), culture-guided bismuth-containing therapy (n = 46) and empirical therapy (n = 30) were 84.0%, 87.0%, and 66.7% (95% confidence interval: 73.8-94.2%, 77.3-96.7%, and 49.8-83.6%), respectively. Overall, culture-guided therapy achieved a higher eradication rate than empirical therapy (85.4% vs 66.7%; 95% confidence interval, 0.4% to 37.0%, P = 0.022). CONCLUSIONS Culture-guided therapy with high-dose PPI achieves a higher eradication rate than empirical therapy with high-dose PPI in the third-line treatment of H. pylori infection. The eradication rate of rescue therapy with bismuth plus two susceptible antibiotics is not inferior to that with three susceptible antibiotics.

[PMID: 35831212 DOI: 10.1016/j.dld.2022.06.019] [Citation(s) in RCA: 28] [Impact Index Per Article: 14.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/18/2022] [Revised: 06/25/2022] [Accepted: 06/25/2022] [Indexed: 12/18/2022]
Abstract
Helicobacter pylori infection is very common and affects more than one-third of adults in Italy. Helicobacter pylori causes several gastro-duodenal diseases, such as gastritis, peptic ulcer and gastric malignancy, and extra-gastric diseases. The eradication of the bacteria is becoming complex to achieve due to increasing antimicrobial resistance. To address clinical questions related to the diagnosis and treatment of Helicobacter pylori infection, three working groups examined the following topics: (1) non-invasive and invasive diagnostic tests, (2) first-line treatment, and (3) rescue therapies for Helicobacter pylori infection. Recommendations are based on the best available evidence to help physicians manage Helicobacter pylori infection in Italy, and have been endorsed by the Italian Society of Gastroenterology and the Italian Society of Digestive Endoscopy.

Helicobacter pylori eradication following first-line treatment failure in Europe: What, how and when chose among different standard regimens? A systematic review. Eur J Gastroenterol Hepatol 2021; 33:e66-e70. [PMID: 33741798 DOI: 10.1097/meg.0000000000002100] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Indexed: 12/25/2022]
Abstract
Cure rate following standard first-line regimens for Helicobacter pylori eradication is decreasing so several patients require two or more treatments. Antibiotic susceptibility-based therapy, advised in current guidelines, is largely impracticable in clinical practice. Some 'standard' regimens (triple therapies based on either levofloxacin or rifabutin, bismuth-based quadruple therapies, sequential, concomitant and hybrid therapies) were empirically used as rescue therapies. We performed a systematic review on recent studies carried out in European countries dealing with these regimens. A total of 24 studies, with 3804 patients, were identified. As second-line therapy, Pylera (89.2%) and sequential therapy (92.5%) achieved significantly higher cure rates as compared to all the other regimens. As third-line therapy, levofloxacin-based therapy (84.1%) and Pylera (83.6%) achieved similarly high cure rates, whereas standard, bismuth-based quadruple therapy (64.1%) achieved the lowest. As a rescue therapy, the success rate was close to 75% following all therapies used, with data on rifabutin-based regimen consolidated in the larger sample size. Overall, levofloxacin-amoxicillin triple therapy achieved higher eradication rates when the 14- rather than 10-day regimen was used (87.1 vs. 72.2%; P = 0.003). Among bismuth-based therapies, Pylera achieved a significantly higher eradication rate than standard quadruple therapy (88 vs. 67%; P < 0.0001). These data suggest that a wise 'therapeutic package' following first-line therapy could be Pylera, levofloxacin- and rifabutin-based therapy, as long as Pylera therapy was not used as a first-line regimen and levofloxacin-based regimen was administered for 14 days.

Abstract
BACKGROUND AND AIMS MATERIALS AND METHODS Consecutive foreigner patients with H. pylori infection following at least one therapy failure were enrolled. All patients underwent upper endoscopy with gastric biopsies used for both histologic examination and culture/susceptibility test. Rescue therapies administered accordingly to susceptibility testing were rifabutin-based therapy, levofloxacin-based therapy, sequential. Pylera was prescribed regardless the resistance pattern. RESULTS A total of 103 (M/F: 27/76, mean age: 41.9 y, range: 18 to 85) were enrolled. The overall resistance rates toward clarithromycin, metronidazole, and levofloxacin were 76.7%, 66%, and 42.7%, respectively, with triple resistance present in 33.9% of bacterial isolates. Eradication rates were 71.4% on 40 patients for rifabutin-based therapy, 82.8% on 42 cases for levofloxacin-based therapy, 75% on 11 patients treated with sequential therapy, and 100% on 10 cases who received Pylera regimen. CONCLUSIONS To our knowledge, this is the first study assessing H. pylori eradication rates in foreigner patients, who failed at least one therapeutic attempt, managed in Italy. Even by using a culture-based approach, the infection was not cured in a definite number of patients.

Abstract
Background/Aims: Curing Helicobacter pylori infection remains challenging for clinicians, as no proposed first-line therapy achieves bacterial eradication in all treated patients so that several patients need two or more consecutive treatments. Bacterial culture with antibiotics susceptibility testing is largely unachievable in Italy, and empiric second-line and rescue therapies are generally used. This study aimed to identify what eradication regimens perform better in Italy, following first-line therapy failure. Methods: We performed a literature search on PubMed for studies on standard therapy regimens used as second-line or rescue treatments performed in adult patients. Studies including modified drug combinations were not considered. Both intention-to-treat and per- protocol analyses were computed for each therapy subgroup. Results: Data from 35 studies with a total of 4830 patients were eventually considered. As a second-line therapy, Pylera® (90.6%) and a sequential regimen (89.8%) achieved eradication rates significantly higher than other therapies. For third-line therapy, a levofloxacin-based regimen and Pylera® achieved comparable eradication rates (88.2% vs. 84.7%; p = 0.2). Among therapies used as fourth (or more) attempts, Pylera® and a rifabutin-based therapy achieved 77.4% and 66.4% cure rates, respectively (p = 0.013). A therapy sequence based on the type of first-line therapy used was proposed. Conclusions: Data obtained through our review indicate that standard therapies for H. pylori eradication can be used when following an appropriate sequence, allowing clinicians to improve the cure rate without resorting to bacterial culture.

Abstract
A complete understanding and good adherence are crucial for successful Helicobacter pylori eradication. Proper frequency of reminders might be helpful to both doctors and patients to maintain adherence during treatment. The study was to evaluate the influence of an intensive follow-up system based on a clinical database on H. pylori eradication therapy. A total of 196 eligible patients were equally and randomly divided into an intensive follow-up group and a control group. Both groups were administered bismuth-containing quadruple therapy for 14 days. Patients in the intensive follow-up group were informed of pre-treatment, including the duration and potential adverse events. Subsequently, they received telephone follow-ups on days 3 and 14 and 3 days before the urea breath test (UBT). The time points were automatically reminded by a follow-up system in the established clinical database. The control group was only informed of pre-treatment information. UBT was performed 4 weeks after treatment in both groups to assess the presence of H. pylori. The eradication rate, patient compliance, and adverse events were calculated and compared. The H. pylori eradication rates of the intensive follow-up and control groups were 94.7% (90/95, 95% CI: 90%-99%) and 92.9% (78/84, 95% CI: 87%-98%), respectively, by PP analysis (p = 0.601), and 91.8% (90/98, 95% CI: 86%-97%) and 81.6% (80/98, 95% CI: 74%-89%) by ITT analysis (p = 0.035). Adverse events occurred in 9 intensive follow-up group patients and 12 in the control group. Adherence was 96.9% (95/98) in the intensive follow-up group and 85.7% (84/98) in the control group. Semi-automatic intensive follow-up contributed to a higher eradication rate and adherence to H. pylori treatment.

Gisbert JP. Empirical or susceptibility-guided treatment for Helicobacter pylori infection? A comprehensive review. Therap Adv Gastroenterol 2020; 13:1756284820968736. [PMID: 33240392 PMCID: PMC7675893 DOI: 10.1177/1756284820968736] [Citation(s) in RCA: 47] [Impact Index Per Article: 11.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/02/2020] [Accepted: 10/01/2020] [Indexed: 02/06/2023] Open
Abstract
Although susceptibility-guided therapy is frequently recommended for Helicobacter pylori infection, the evidence available to date supporting this strategy is limited. The aim of the present article is to review the advantages and limitations of the susceptibility-guided and the empirical strategies to treat this infection. We performed a bibliographic search to identify studies investigating H. pylori susceptibility-guided therapy. Culture is not the only way to assess antibiotic resistance, as different polymerase chain reaction-based approaches have been developed as alternative methods. For detecting H. pylori antimicrobial resistance, a molecular approach based on a stool sample might enable more convenient, time-saving methods. Unfortunately, the antimicrobial susceptibility cannot be obtained in all cases. Furthermore, antibiotic susceptibility testing in clinical practice yields useful information only for a few antibiotics: clarithromycin, metronidazole, and quinolones. In addition, susceptibility towards clarithromycin and metronidazole in vitro does not necessarily lead to eradication in vivo. In the case of H. pylori therapy failure, we should not re-administer any of the antibiotics against which H. pylori has probably become resistant. Our updated meta-analysis showed that susceptibility-guided treatment is not better than empirical treatment of H. pylori infection in first-line therapy if the most updated quadruple regimens are empirically prescribed, and similar efficacy results were also demonstrated with the two strategies for second-line therapy. Cumulative H. pylori eradication rate with several successive rescue therapies empirically prescribed reaches almost 100%. Finally, the studies that have evaluated the cost-effectiveness of the susceptibility-guided treatment have achieved contradictory results. In summary, we can conclude that the evidence is too limited to support the generalized use of susceptibility-guided therapy for H. pylori treatment in routine clinical practice, either as first-line or as rescue treatment. Nevertheless, it would be recommended that susceptibility tests are performed routinely, even before prescribing first-line treatment, in specialized centers with an interest in H. pylori management.

Antimicrobial Efficacy of Five Probiotic Strains Against Helicobacter pylori. Antibiotics (Basel) 2020; 9:antibiotics9050244.

Abstract
Treatment of Helicobacter pylori (H. pylori) infection is a challenge for clinicians. The large increase in drug-resistant strains makes the formulation of new therapeutic strategies fundamental. The frequent onset of side effects during antibiotic treatment (mainly due to intestinal dysbiosis) should not be underestimated as it may cause the interruption of treatment, failure of H. pylori eradication and clonal selection of resistant bacteria. Probiotic integration during antibiotic treatment can exert a dual function: a direct antagonistic effect on H. pylori and a balancing effect on dysbiosis. Therefore, it fulfills the definition of a new therapeutic strategy to successfully treat H. pylori infection. Data reported in literature give promising but discrepant results. Aim: To assess in vitro bacteriostatic and bactericidal activity of probiotic strains against H. pylori. Materials and methods: L. casei, L. paracasei, L. acidophilus, B. lactis and S. thermophilus strains were used. Agar well diffusion and time-kill curves were carried out to detect bacteriostatic and bactericidal activity, respectively. Results: All probiotic strains showed both bacteriostatic and bactericidal activity vs. H. pylori. Conclusions: Such findings prompted us to plan a protocol of treatment in which probiotics are given to infected patients in association with antibiotic therapy.
