Helicobacter pylori is a gram-negative bacterium that is essentially confined to the gastric mucosa. It is considered the cause of acute and chronic superficial gastritis and chronic atrophic gastritis.1 Recently, several reports suggested that H pylori could play a role in triggering psoriasis.1 This study was designed to determine whether H pylori infection could be found in a significant number of children and teenagers with psoriasis.
