According to a pilot study published in the medical journal Acta Dermato-Venereologica by Dr. Camilo Diaz and colleagues in England, there may be a relationship between the bumps (papules) and pimples (pustules) of subtype 2 rosacea and infection with Helicobacter pylori bacteria.1
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.
Limited studies have suggested that a bacterium commonly associated with peptic ulcers and other gastric disorders, called Helicobacter pylori, may play a role in triggering rosacea in some patients.
Evidence of H. pylori was found in 19 of 20 rosacea patients in one study and in 26 of 31 rosacea patients in another, according to Dr. Richard B. Odom, chairman of dermatology at the University of California at San Francisco.
