Abstract
Helicobacter pylori was suggested to have a causative role in rosacea, and its eradication was said to be associated with improvement ofrosacea.

All patients were subjected to thorough history taking with stress on factors that could flare up the rosacea. Then rosacea severity was graded according to Henderson et a I (1995).

Gastroduodenscopy was done for 28 patients, and antral and duodenal biopsies were taken. These biopsies were subjected to direct Gram smear, direct urease test and culture. All patients were given anti-//. pylori treatment in the form of Amoxacillin and Metronidazole for 10 days. Only 26 patients completed the follow up period. They wrere reassessed clinically at the end of treatment, 1 month and 6 months after treatment. Another blood sample was taken to detect anti-// pylori antibodies at the end of follow up period.
