A recent study suggested that treatment of Helicobacter pylori, a bacterium associated with peptic ulcers and other gastric disorders, may benefit the often small portion of rosacea patients who harbor this infection. However, another study has found that H. pylori itself does not appear to be a major factor.

The National Rosacea Society announced that the first research proposals have been selected for funding by its medical advisory board as part of the Society's new research grants program to encourage and support the advancement of scientific knowledge of rosacea and how to control it.
