Review article: tackling the "dyspeptic problem".

Area of Science:

• Gastroenterology
• Internal Medicine
• Clinical Management

Background:

• Dyspepsia management presents clinical controversies, particularly regarding Helicobacter pylori (H. pylori) status.
• Primary care physicians and gastroenterologists require updated information on dyspepsia treatment options.

Purpose of the Study:

• To review H. pylori eradication in non-ulcer dyspepsia (NUD).
• To examine therapy for NUD unrelated to H. pylori.
• To assess H. pylori testing as an alternative to routine endoscopy for uncomplicated dyspepsia.

Main Methods:

• Literature review of H. pylori eradication and dyspepsia treatment strategies.
• Analysis of clinical trial data comparing H. pylori eradication, PPI therapy, and placebo.
• Evaluation of diagnostic approaches including non-invasive H. pylori testing versus endoscopy.

Main Results:

• H. pylori eradication in NUD offers superior symptom resolution, reduces ulcer and gastric cancer risks, and mitigates risks associated with long-term proton pump inhibitor (PPI) therapy.
• For NUD patients with normal endoscopy and no H. pylori, PPI therapy is more effective than placebo for symptom control, particularly in those with symptoms or oesophageal pH-metry indicative of gastroesophageal reflux disease (GORD).
• Non-invasive H. pylori testing is a viable option for younger dyspeptic patients lacking alarm symptoms and not using non-steroidal anti-inflammatory drugs (NSAIDs).

Conclusions:

• H. pylori eradication is recommended for patients diagnosed with NUD.
• PPI therapy demonstrates superiority over placebo for NUD patients without H. pylori, especially when GORD symptoms are present.
• H. pylori testing may serve as a substitute for endoscopy in uncomplicated dyspepsia among young patients without alarm symptoms or NSAID use.
