Helicobacter pylori infection is thought to be a causal factor in urticaria. Dermographism is the most common type of physical urticaria in which the etiological factors are unclear.


We aimed to determine the etiologic role of Helicobacter pylori infection in dermographism.


We assessed the frequency of Helicobacter pylori infection in 22 patients with dermographic urticaria and 14 patients with Helicobacter pylori positivity were evaluated whether they have dermographism. The presence of Helicobacter pylori infection was determined by rapid urease test.


Six of 22 patients had Helicobacter pylori infection. And 5 patients with Helicobacter pylori positivity have dermographism.


Our results indicate that the pathogenic role of Helicobacter pylori in dermographic urticaria is highly doubtful. It may be a triggering factor in patients with dermographic urticaria.
