[Antigen detection in stools as a first choice for laboratory diagnosis of Helicobacter pylori disease].

Background: Several techniques have been suggested for Helicobacter pylori infection diagnosis, invasive (histology) and not invasive (Urea Breath Test C13, or serological assays). An enzyme immunoassay able to detect Helicobacter pylori antigen directly in stool specimens was recently developed. A study was carried out in order to evaluate the sensibility and the specificity of this test comparing it with the Urea Breath Test C13 and histology.

Dual vs. triple therapy for childhood Helicobacter pylori gastritis: a double-blind randomized multicentre trial.

Background: Data on the efficacy of eradication treatment for Helicobacter pylori gastritis in children are scarce.

Aim: To evaluate the efficacy of triple therapy with lansoprazole plus amoxicillin and tinidazole vs. dual therapy with amoxicillin and tinidazole in a double-blind randomized multicentre trial, and the usefulness of eradication in terms of long-term symptom resolution.
