    Abstract:
    BACKGROUND AND OBJECTIVE: Irritable Bowel Syndrome (IBS) has a substantial impact on health-related quality of life (HR-QoL) but high-quality data pre- and post-treatment using the IBS-Quality of Life (IBS-QOL) measure are limited. The objective of this study was to evaluate the changes from baseline of the IBS-QOL scores, symptom scores and health economic data in IBS patients, after 4 and 8 weeks of treatment with mebeverine hydrochloride or pinaverium bromide. METHODS: This was a prospective observational cohort study in patients with IBS, diagnosed using the Rome III criteria in four countries (Poland, Egypt, Mexico and China). RESULTS: A total of 607 patients were enrolled. At baseline, the IBS-QOL total scores were 52.0 in Poland, 48.9 in Egypt, 51.9 in Mexico, 76.4 in China and 56.4 overall. Increases in IBS-QOL total score were statistically significant at Weeks 4 and 8 overall and in each country (overall: 11.8 at Week 4, 24.3 at Week 8; p < 0.001). Improvements were shown in all IBS-QOL subscales and scores. Symptoms and health economic outcomes were improved. Furthermore, the favourable safety profile of these treatments was confirmed in this study. CONCLUSIONS: This study demonstrated that IBS patients have a substantially reduced HR-QoL and that treatment with mebeverine hydrochloride or pinaverium bromide improved HR-QoL.
