Mr. Mike, a 50-year-old male, was diagnosed with H. pylori infection after presenting with symptoms of recurring abdominal pain and indigestion. He was prescribed a standard triple therapy regimen consisting of a proton pump inhibitor (PPI), clarithromycin, and amoxicillin for a 14-day duration. However, during a follow-up appointment after completing the treatment, Mr. Mike reports that his symptoms have not improved, and he continues to experience abdominal discomfort and bloating.

To determine the cause of treatment failure, the physician orders a repeat stool antigen test to check for the persistence of H. pyvlori infection. The test results confirm the presence of the bacteria, indicating treatment failure. The physician performed a susceptibility test to assess the sensitivity of the H. Pylori to different antibiotics and the results were: Amoxicllin Sensitive Clarithromycin Resistant Metronidazole Sensitive Levofloxacin Resistant Tetracycline Sensitive Knowing that Mr Mike has no medical history except the H.

Esomeprazole 40 mg once daily, amoxicillin 1 g twice daily, metronidazole 500 mg twice daily, and clarithromycin 250 mg twice daily for 7 days b. Esomeprazole 40 mg once daily, tetracycline 500 mg four times daily, metronidazole 250 mg four times daily, and bismuth subsalicylate 525 mg four times daily for 14 days Omeprazole 20 mg twice daily, levofloxacin 500 mg once daily, and amoxicillin 1 C g twice daily for 10 days Omeprazole 20 mg twice daily, metronidazole 50 mg twice daily, and clarithromycin 500 mg twice daily for
