Henoch-Schönlein purpura associated with Helicobacter pylori infection in a child.

Henoch-Schönlein purpura is an acute leukocytoclastic vasculitis that primarily affects children. Henoch-Schönlein purpura is often associated with an infection, and a wide variety of infectious agents have been implicated in the pathogenesis. We report a child with Henoch-Schönlein purpura associated with Helicobacter pylori infection. Treatment of the Helicobacter pylori infection was accompanied by prompt resolution of the Henoch-Schönlein purpura.
