The ACGs 2007 treatment guideline on the management of H. pylori infection (26) listed the following as established indications for diagnosis and treatment:

## Indications
- Active PUD (gastric or duodenal).
- Confirmed history of PUD (not previously treated for H. pylori)
- Gastric MALT lymphoma (low grade)
- After endoscopic resection of EGC
Recommended  first-line treatment for Helicobacter pylori
: Several PPI, Clarithromycin, and Amoxicillin combinations have achieved FDA approval ,PPI, Clarithromycin, Metronidazole is not an FDA approved treatment regimen.
: PPI, Bismuth, Tetracycline and metronidazole prescribed separately is not an FDA approved treatment regimen.However ,Pylera, a combination product containing Bismuth subcitrate,Tetracycline , Metronidazole combination with PPi for 10 days is an FDA approved regimen.
Adjuvant therapy in the treatment of H. pylori infection:
Emerging evidence suggests an inhibitory effect of Lactobacillus
and Bifidobacterium species on H. pylori. Furthermore,
these probiotic strains may also help to reduce the side effects
-f eradication therapies and improve compliance with therapy.

# Selection of firstline Treatment

## Diagnostic testing
The American Journal of Gastroenterology guidelines recommend that endoscopy should be performed to rule out peptic ulcer disease, esophagogastric malignancy, and other rare upper gastrointestinal tract disease in the following settings:
- Dyspeptic patients more than 55 years old OR
- Dyspeptic patients with alarm features
- Bleeding
- Anemia
- Early satiety
- Unexplained weight loss (> 10% body weight)
- Progressive dysphagia
- Odynophagia
- Persistent vomiting
- A family history of gastrointestinal cancer
- Previous esophagogastric malignancy
- Previous documented peptic ulcer, lymphadenopathy, or an abdominal mass
In patients aged 55 years or younger with no alarm features, two management options may be considered:
- Test-and-treat strategy using a validated noninvasive test (urea breathing test or stool antigen test) for H. pylori and a trial of acid suppression if eradication is successful but symptoms do not resolve  preferable in populations with a moderate to high prevalence of H. pylori infection ( 10%)
- Empiric trial of acid suppression with a proton pump inhibitor for 48 weeks  preferable in low prevalence situations
Repeat endoscopy is not recommended once a firm diagnosis of functional dyspepsia has been established, unless new symptoms or alarm features develop.  Testing to prove H. pylori eradication is most accurate if performed 4 weeks after the completion of therapy.
