[A case of mucosa-associated lymphoid tissue lymphoma with penicillin allergy successfully treated with levofloxacin, minomycin and rabeprazole].

A 52-year-old Japanese woman was referred to our Institute because of Helicobacter pylori(H. pylori)-positive gastric mucosa-associated lymphoid tissue(MALT)lymphoma. Since she had a penicillin allergy, we could not eradicate H. pylori using the standard triple therapy including amoxicillin. Additionally, H. pylori was resistant to both clarithromycin and metronidazole. So she was treated with minomycin (MINO), levofloxacin (LVFX), and rabeprazole (RPZ) based on a drug sensitivity test. MINO+LVFX+RPZ appear to be a promising, appropriate, and well-tolerated eradication regimen for H. pylori demonstrating resistance to both clarithromycin and metronidazole, and for patients who are allergic to penicillin.
