Randomized Clinical Trial Comparing Concomitant and Tailored Therapy for Eradication of Helicobacter pylori Infection. J Pers Med 2021; 11:jpm11060534. [PMID: 34207870 PMCID: PMC8229321 DOI: 10.3390/jpm11060534] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/26/2021] [Revised: 06/03/2021] [Accepted: 06/07/2021] [Indexed: 12/12/2022] Open
Abstract
As high clarithromycin resistance (>20%) in the Split-Dalmatia region of Croatia hinders the treatment of H. pylori infection, the primary objective of this study was to compare concomitant quadruple with the tailored, personalized therapy as first-line eradication treatment of H. pylori. In an open-label, randomized clinical trial, 80 patients with H. pylori infection were randomly assigned to either concomitant (esomeprazole 40 mg, amoxicillin 1 gr, metronidazole 500 mg, clarithromycin 500 mg, twice daily for 14 days) or tailored therapy in accordance with the results of the antimicrobial susceptibility testing. Eradication status was assessed 4 weeks after treatment. Eradication rates were significantly higher in tailored group than in concomitant group both in intention-to-treat (70 vs. 92.5%, p = 0.010) and per-protocol (87.5 vs. 100%, p = 0.030) analysis in the setting of increasing antibiotic resistance (clarithromycin 37.5%, metronidazole 17.5%, dual resistance 10%). Adverse effects were more frequent in the concomitant group (32.5 vs. 7.5%, p = 0.006). Tailored therapy achieves higher eradication with a lower adverse events rate. With the increasing resistance of H. pylori strains to antibiotic treatment, eradication regimes with such characteristics should be strongly considered as a reasonable choice for first-line treatment.

Adherence to Maastricht V/Florence consensus report for the management of Helicobacter pylori infection among primary care physicians and medical students in Croatia: A cross-sectional study. Helicobacter 2021; 26:e12775. [PMID: 33368852 DOI: 10.1111/hel.12775] [Citation(s) in RCA: 11] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/23/2020] [Revised: 11/09/2020] [Accepted: 11/15/2020] [Indexed: 12/15/2022]
Abstract
BACKGROUND Helicobacter pylori (H pylori) eradication is becoming increasingly difficult. The aim of our study was to determine the knowledge of current guidelines and attitude in the diagnosis and treatment of H pylori infection in primary care physicians (PCPs) and medical students in Croatia. MATERIALS AND METHODS A study was conducted among PCPs and medical students to evaluate adherence to Maastricht V consensus guidelines. Questionnaire was distributed by e-mail to 2338 PCPs offices in Croatia and to the medical students from the University of Split School of Medicine. Responses were collected electronically from June 22 to August 22, 2020. RESULTS Two hundred forty-nine PCPs and 169 medical students were included in the study. Bismuth or non-bismuth-based quadruple therapy as first-line treatment for H pylori was the choice of 4.8% of PCPs and 13% of students, while 66.3% PCPs and 79.9% students would choose clarithromycin-based triple therapy. Bismuth-based quadruple therapy was the most preferred second line of treatment for 45.4% of PCPs and 34.9% of students. Only 2.8% PCPs and 7.1% of students would correctly recommend first and second line of treatment for H. pylori infection. A larger proportion of students than PCPs would prefer C13-urea breath test (50.3% vs 6.4%). Only 59.0% PCPs would treat for H pylori in all patients including the asymptomatic ones. Students more frequently recognized the link between H pylori and gastric cancer compared with PCPs (92.9% vs 73.5%). CONCLUSIONS Primary care physicians and medical students' knowledge of H pylori guidelines are insufficient in Croatia and ask for additional training.

Abstract
BACKGROUND The primary objective of this study was to compare concomitant and hybrid therapy in the first line eradication treatment of Helicobacter pylori infection in Split-Dalmatia County, Croatia, in which clarithromycin resistance is above 20%. The secondary objective of the study was to determine and compare compliance and adverse events rate between these therapeutic protocols. MATERIALS AND METHODS In an open-label, randomised clinical trial 140 patients total with H. pylori infection were randomly assigned to either concomitant (esomeprazole 40 mg, amoxicillin 1 g, metronidazole 500 mg, clarithromycin 500 mg, twice daily for 14 days) or hybrid (esomeprazole 40 mg and amoxicillin 1 g twice daily during 14 days with adding metronidazole 500 mg and clarithromycin 500 mg twice daily, in the last 7 days,) treatment group. RESULTS Eradication rates for concomitant group and hybrid therapy group were 84.1% (58/69) and 83.1% (59/71) respectively in the intention-to-treat analysis and 96.7% (58/60) and 95.2% (59/62) in per-protocol analysis. There was no significant difference between the groups (ITT analysis: P = 0.878; PP analysis: P = 0.675). Adverse events were more frequent in the concomitant group (33.3% vs 18.3%, P = 0.043). There was no difference among groups regarding compliance rate. CONCLUSION Hybrid therapy has similar eradication rate as concomitant therapy, with lower adverse events rate. In the era of increasing antibiotic resistance, eradication regime with less antibiotic's usage, as hybrid therapy, should be reasonable first line treatment choice for H. pylori infection.

Abstract
"Heteroresistance" is a widely applied term that characterizes most of the multidrug-resistant microorganisms. In microbiological practice, the word "heteroresistance" indicates diverse responses to specific antibiotics by bacterial subpopulations in the same patient. These resistant subpopulations of heteroresistant strains do not respond to antibiotic therapy in vitro or in vivo. Presently, there is no standard protocol available for the treatment of infections caused by heteroresistant Helicobacter pylori in clinical settings, at least according to recent guidelines. Thus, there is a definite need to open a new discussion on how to recognize, how to screen, and how to eliminate those problematic strains in clinical and environmental samples. Since there is great interest in developing new strategies to improve the eradication rate of anti-H. pylori treatments, the presence of heteroresistant strains/clones among clinical isolates of the bacteria should be taken into account. Indeed, increased knowledge of gastroenterologists about the existence of heteroresistance phenomena is highly required. Moreover, the accurate breakpoints should be examined/determined in order to have a solid statement of heteroresistance among the H. pylori isolates. The primary definition of heteroresistance was about coexistence of both resistant and susceptible isolates at the similar gastric microniche at once, while we think that it can be happened subsequently as well. The new guidelines should include a personalized aspect in the standard protocol to select a precise, effective antibiotic therapy for infected patients and also address the problems of regional antibiotic susceptibility profiles.
