RESUMO
Italy's shift to a tertiary economy has modified the working market, concentrating demand also on unqualified one, which includes most immigrants. It is also well established that low socio-economical conditions are associated with an increased prevalence of H. pylori infection. The aims of this study were to compare: (1) the efficacy of a 7 days triple therapy in immigrant and in Italian patients; (2) the prevalence of PUD between these two groups of patients. A total of 116 consecutive immigrant and 112 Italian H. pylori infected patients were recruited between 2007 and 2008. Patients underwent (13)C-UBT, endoscopy with biopsies, and were offered a 7-day triple therapy. Eradication rate (ER) was assessed 8 weeks after the end of the treatment using (13)C-UBT. The two populations differed for median age (p < 0.01), prevalence of PUD (p < 0.01), and smoking status (p < 0.01). The ER according to the ITT analysis was 70% for Italian and 48.3% for immigrant (p < 0.01). Multivariate analysis including country of origin, sex, age, PUD, smoking, and alcohol status found that immigrant had an adjusted OR for not eradicating of 2.14 (p = 0.03). In immigrant patients resident in Italy, performance of triple therapy was lower than expected. Further studies are demanded to confirm and clarify these intriguing results.

Assessment of symptoms should be one of the main outcome measures in dyspepsia clinical trials. This requires a reliable, valid and responsive questionnaire that measures the frequency and severity of dyspeptic symptoms. The Short-Form Leeds Dyspepsia Questionnaire (SF-LDQ) has been proven to fulfil these criteria in its original version in the English language. The aim of the study was to assess the internal consistency, reliability, validity and responsiveness of the Italian version of the SF-LDQ in primary and secondary care. Unselected primary and secondary care patients completed the Italian version of the SF-LDQ. Test-retest reliability was assessed after 2 days. Validity was measured by comparison with diagnosis made by physicians. Responsiveness was determined before and after treatment for endoscopically proven disease. The SF-LDQ was administered to 311 patients in primary care and 179 in secondary care patients. Internal consistency, as judged by the Cronbach's α, was 0.90. Pearson's correlation coefficient for test-retest reliability was 0.92. The SF-LDQ had a sensitivity of 80% and a specificity of 82%. A highly significant response to change was also observed (p = 0.001). The Italian SF-LDQ is a reliable, valid and responsive self-completed outcome measure for quantifying the frequency and severity of dyspeptic symptoms.
