title: High incidence of Helicobacter pylori infection in patients with systemic sclerosis: association with Sicca Syndrome.
abstract: To test the incidence of Helicobacter pylori (HP) infection in patients affected by Systemic Sclerosis (SSc) a swift urease test, followed by histologic confirmation for the presence of HP was verified in 35 SSc patients. Serum samples from 46 patients were tested for HP IgG antibodies by an enzyme-linked immunosorbent assay. Urease test demonstrated the presence of HP in 23 patients out of 35 (66&#x0025;); 12 of them were negative to colonization. A Sicca syndrome, with abnormal Schirmers test and dry mouth was detected in 66&#x0025; of the patients. 78&#x0025; of the patients with Sicca syndrome had a concomitant HP infection, compared to 42&#x0025; of those without the syndrome (p=0,029). Altered peristalsis and reduced salivary clearance usually encourage HP infection. In patients with Systemic Sclerosis we found an enhanced frequency of HP infection.
