Rosacea

There is increasing evidence for systemic effects of gastric H. pylori infection which may result in extragastrointestinal disorders. This review summarizes the available medical literature up to September 1999, identified through a MEDLINE research including own studies, regarding H. pylori and skin diseases. Due to current knowledge best evidence for a potential link of H. pylori infection exists for chronic urticaria although the data are still conflicting. Thus, the search for H. pylori should be included in the diagnostic management of chronic urticaria. With regard to other skin diseases such as rosacea , hereditary or acquired angioedema due to C1-esterase inhibitor deficiency, systemic sclerosis, Schönlein-Henoch purpura, Sjögren's syndrome, sweet's syndrome, and atopic dermatitis only single of few cases have been reported so far. Thus, we clearly need further randomized, double-blind and placebo-controlled studies including adequate diagnostic schedules, sufficient er...

Rosacea is a common condition of unknown etiology usually accompanied by gastrointestinal symptoms and favorably responding to the treatment with antibiotics. This study was designed to examine the prevalence of gastric Helicobacter pylori (Hp) infection verified by 13C-UTB-test, CLO, Hp culture and serology (IgG) in patients with rosacea. Gastroduodenoscopy was combined with pentagastrin secretory test and antral and fundic biopsy samples were taken for histological evaluation (the Sydney system). Blood samples were also taken for the determination of plasma gastrin using RIA and plasma interleukin (IL)-8 and tumor necrosis factor alpha (TNFalpha) using ELISA. This study was performed in 60 patients, 31-72 year old, with visible papules and pustules associated with erythema and flushing on the face and on 60 age- and gender-matched patients without any skin diseases but with similar as in rosacea gastrointestinal symptoms but without endoscopic changes in gastroduodenal mucosa (non-...
