In recent years some authors have reported a possible correlation between Helicobacter pylori (Hp) and dermatological diseases such as rosacea. In this study we evaluated serum IgG and IgA anti‐Hp in a group of 48 patients with rosacea. IgG antibodies were present in 81% of the rosacea patients with dyspepsia and 16% of the rosacea patients without dyspeptic symptoms. Serum IgG and IgA anti‐Hp were detected by means of an enzymatic immunoabsorption test (enzyme‐linked immunosorbent assay: ELISA). In addition, an evaluation of the anti‐CagA antibodies by means of an immunoenzymatic method was carried out (ELISA, RADIM). IgA anti‐Hp was present in 62% of patients with dyspepsia and in 6% of patients with no upper gastrointestinal symptoms. Anti‐CagA antibodies were seen to be present in 75% of patients with both rosacea and gastric symptomatology, and were prevalent in patients affected by rosacea with papular symptoms in respect to rosacea with erythematous symptoms. The data that emerge from our case studies appear to confirm the hypothesis put forward by scientists who propose a correlation between the two clinical presentations rather than an inverse hypothesis of total independence.
