What complications can arise from chronic Helicobacter pylori infection?
Although most patients are asymptomatic, approximately 10% to 15% of patients with chronic Hp infection will develop ulcers, gastric adenocarcinoma, or gastric lymphoma (“MALT lymphoma”). Early stages of MALT lymphoma may be cured by antibiotic and antisecretory therapy alone. More advanced stages, however, often require chemotherapy, radiation, or surgery.
