So this multinational multi-center randomized controlled trial was designed to evaluate the efficacy of tetracycline +levofloxacin for HP eradication. Methods: During a 6-month period, all of the cases with HP infection in eight referral tertiary centers of three countries were included and randomly allocated to receive either tetracycline + levofloxacin or clarithromycin plus amoxicillin quadruple regimen for two weeks. For all of the participants, pantoprazole was continued for 4 more weeks and after one to two weeks of off-therapy, they underwent urea breath test C13 to prove eradication. Results: Overall 788 patients were included (358 male (45.4%), average age 44.2 years). They were diagnosed as having non-ulcer dyspepsia (516 cases, 65.5%), peptic ulcer disease (PUD) (234 cases, 29.69%), and intestinal metaplasia (38 cases, 4.8%). Racially 63.1% were Caucasian, 14.5% Arab, 15.6% African, and 6.1% Asian. The participants were randomly allocated to groups A and B to receive either tetracycline + levofloxacin or clarithromycin. Among groups A and B in intention to treat (ITT) and per protocol (PP) analysis, 75.2% &amp; 82.1% (285 cases) and 67.5% &amp; 70.1% (276 cases) of participants achieved eradication, respectively (P\u2003=\u20030.0001). The complete compliance rate in groups A and B were 84.4% and 83.6%, respectively. During the study, 33.5% of the participants in group A (127 cases) reported side effects while the complication rate among group B was 27.9% (114 cases, P\u2003=\u20030.041). The most common complaints among groups A and B were nausea and vomiting (12.6% &amp; 9.3%) and abdominal pain (4.48% &amp; 2.68%), respectively. The rate of severe complications that caused discontinuation of medication in groups A and B were 2.1% and 1.46%, respectively (P\u2003=\u2003679). In subgroup analysis, the eradication rates of tetracycline+levofloxacin among patients with non-ulcer dyspepsia, PUD, and intestinal metaplasia were 79.4%, 88.1%, and 73.9%, respectively. These figures in group B (clarithromycin base) were 71.3%, 67.6%, and 61.5% respectively (P\u2003=\u20030.0001, 0.0001, and 0.043). Conclusion: Overall, the combination of tetracycline+levofloxacin is more efficient for HP eradication in comparison with clarithromycin+amoxicillin despite more complication rate. In areas with a high rate of resistance to clarithromycin, this therapeutic regimen could be an ideal choice for HP eradication, especially among those who were diagnosed with PUD.<\/jats:p>","DOI":"10.34172\/mejdd.2023.314","type":"journal-article","created":{"date-parts":[[2023,4,18]],"date-time":"2023-04-18T11:19:13Z","timestamp":1681816753000},"page":"12-18","update-policy":"https:\/\/doi.org\/10.34172\/crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Levofloxacin+Tetracycline Quadruple Regimen for Eradication of <i>Helicobacter pylori<\/i>: A Multicenter Multinational Randomized Controlled Trial"],"prefix":"10.34172","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6857-6151","authenticated-orcid":true,"given":"Pezhman","family":"Alavinejad","sequence":"first","affiliation":[{"name":"Alimentary Tract Research Center, Imam Khomeini Hospital Clinical Research Development Unit, School of Medicine, Ahvaz Jundishapur University of Medical Sciences, Ahvaz, Iran"},{"name":"World Endoscopy Organization Emerging Star Group, WEO, Munich, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Morteza","family":"Nayebi","sequence":"additional","affiliation":[{"name":"Shahid Rajaie Cardiovascular, Medical & Research Center, Tehran, Iran"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Abazar","family":"Parsi","sequence":"additional","affiliation":[{"name":"Alimentary Tract Research Center, Imam Khomeini Hospital Clinical Research Development Unit, School of Medicine, Ahvaz Jundishapur University of Medical Sciences, Ahvaz, Iran"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Eman","family":"Abdelsameea","sequence":"additional","affiliation":[{"name":"Assistant Professor of Hepatology and Gastroenterology, National Liver Institute, Menoufia University, Egypt"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mohammed Hussien","family":"Ahmed","sequence":"additional","affiliation":[{"name":"Lecturer Hepatology Gastroenterology and Infectious Diseases, Faculty of Medicine, Kafrelsheikh University, Cairo, Egypt"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ahmad","family":"Hormati","sequence":"additional","affiliation":[{"name":"Gastrointestinal and Liver Diseases Research Center, Firouzgar Hospital, Iran University of Medical Sciences, Tehran, Iran"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dao","family":"Viet Hang","sequence":"additional","affiliation":[{"name":"Lecturer, Internal Medicine Faculty -
