Background
- Slow-growing Gram-negative microaerophilic bacillus with a curve, gull-wing, or spiral appearance
- Oxidase-positive and urease-positive
- Major cause of peptic ulcer disease and gastric cancer
Management
- Treatment is with combination therapy for 14 days followed by confirmation of eradication
- First-line:
- PBMT (PPI, bismuth, metronidazole, tetracycline) (BMT Quad)
- PAMC (PPI, amoxicillin, metronidazole, clarithromycin) (CLAMET Quad)
- PAC (PPI, amoxicillin, clarithromycin), PMC (PPI, metronidazole, clarithromycin), or PAM (PPI, amoxicillin, metronidazole) only in areas with clarithromycin resistance <15% or with proven high local eradication rates >85%
- Prior treatment failure:
- PBMT (PPI, bismuth, metronidazole, tetracycline)
- PAL (PPI, amoxicillin, levofloxacin)
- PAR (PPI, amoxicillin, rifabutin) for 10 days, as last-line
- Doses:
- PBMT
- Bismuth subsalicylate 524 mg (2x 262 mg tablets) PO qid
- Metronidazole 500 MG PO tid or qid
- PPI: esomeprazole 20 mg, lansoprazole 30 mg, omeprazole 20 mg, pantoprazole 40 mg, or rabeprazole 20 mg
- Some areas use double dosing
- Tetracycline 500 mg PO qid
- Others
- Amoxicillin 1000 mg PO bid
- Clarithromycin 500 mg PO bid
- Levofloxacin 500 mg PO daily
- Metronidazole 500 mg PO bid
- Rifabutin 150 mg PO bid
- PPI as above
- PBMT
- Duration: 14 days
- Confirmation of eradication should be done 4 weeks following treatment
- Recommended order of treatment, if persistently positive:
- PBMT (or PAMC)
- PAMC (or PBMT)
- PAL
- PAR vs. repeat endoscopy for culture and susceptibility testing
