RESUMO
OBJECTIVES: Aim of the study was to investigate the effects of 1-year therapy by different proton pump inhibitors (PPIs) on epithelial tissue and surrounding inflammatory changes in Barrett's oesophagus, in patients who have abandoned invasive therapy. METHODS: A group of 120 patients (sampled in 60-month period, from 61201 upper gastrointestinal endoscopies) who were diagnosed both, endoscopically and pathohistologically with Barrett's oesophagus, and who have abandoned invasive therapeutic approach were enrolled in study. Treatment with different PPIs was initiated and continued for a year. At the end of treatment, patients were reassessed by endoscopy with tissue biopsy and pathohistological analysis. RESULTS: No difference in regenerating squamous epithelium or degree of dysplasia was seen between different treatment groups. Interestingly, most patients receiving pantoprazole (94%) ended up with thinner squamous epithel (P<0.0001). The squamous epithel was consider thinner only if its total thickness, measured on histological specimen, was smaller for more than 50% of the thickness before therapy. Significantly less of difference (P<0.0014) was seen with patients receiving lansoprazole (65%) and (P<0.003) omeprazole (50%). CONCLUSION: Regeneration of the squamous epithel was the same for all PPIs but not good enough to stop the progression of the disease.

This epidemiological study of irritable bowel syndrome (IBS) was the first one of the type in Croatia. The aim of the study was to determine prevalence and association between IBS and gender, age, education and urban/rural living. Study design included a questionnaire based on Rome criteria, which was send to 500 study subjects by post. Study population matched the adult population of Croatia according last census. Study result showed a high prevalence of IBS: i.e. 28% (10% of males and 18% of females). Age, education and urban/rural type of living were not related to the prevalence of IBS. Logistic regression gave gender-body mass index (BMI) model for IBS determination: the relative risk for getting IBS in females was by 165% higher than in males and BMI increase of 5 kg/m2 increased the risk of IBS by 36%. BMI was indicated as a possible new factor of IBS prevalence.
