SUMMARY
BackgroundAnalyses of a trial in constipated patients indicated that lubiprostone may be an effective treatment for irritable bowel syndrome with constipation.
SUMMARY BackgroundIrritable bowel syndrome with constipation (IBS-C) significantly decreases quality of life and the ability to perform daily living activities.
Due to increasing resistance to commonly used antibiotics, the World Health Organization and Food and Drug Administration have advocated the development of new therapeutic regimens for Helicobacter pylori (H. pylori). This phase three, double-blind study (ERADICATE Hp) randomized (2:1) treatment-naïve adults with H. pylori infection and dyspepsia to RHB-105 (an all-in-one combination of omeprazole 40 mg, amoxicillin 1000 mg, and rifabutin 50 mg) or an identically-appearing placebo, both administered every 8 h for 14 days. The H. pylori eradication rate with RHB-105, using a modified intent-to-treat (mITT) population of subjects who received ≥1 dose of study drug and had test-of-eradication performed 28–35 days post-completion of therapy, was compared (one-sample Z-test) to a literature-derived comparator rate of 70% and success rate with physician-selected standard-of-care given to placebo failures. The mITT H. pylori eradication rate (95% CI) with RHB-105 of 89.4% (82.0–96.8%) was greater than both the literature-derived comparator rate (P < 0.001) and the standard-of-care rate of 63.0% (44.8–81.1%) (P = 0.006). Adverse events with an incidence ≥5% for RHB-105 were diarrhea (12.7%), headache (11.9%), chromaturia (9.3%), abdominal tenderness (6.8%), and dizziness (5.1%). No leukopenia was noted. RHB-105 (Talicia®) proved to be a safe and effective empiric therapy for H. pylori eradication.
Diabetes is strongly associated with Type 2 CRS in a nationally representative multi-ethnic population and must be considered when treating patients. Longitudinal studies should further examine this association.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
