Since the identification of Helicobacter pylori
in 1983, this pathogen has become the dominant focus of investigation in a variety of gastrointestinal tract disorders, including peptic ulcer disease
, nonulcer dyspepsia
, and gastric carcinoma. During the past 7 years, the efficacy of a variety of antimicrobial single, dual, and triple therapy regimens--including the use of acid-suppressive agents, such as proton pump
inhibitors, and histamine2-receptor antagonists--in the eradication of H pylori have been investigated. Newer treatment approaches, such as dual therapy (proton pump inhibitor + 1 antimicrobial agent) and 7-day regimens have shown a high degree of success and have the potential to improve compliance. However, the optimal regimen, in terms of cost, efficacy, and tolerability, and optimal length of treatment still remains to be determined.
