Exploratory Study of Tegaserod for Dyspepsia in Women Receiving PPIs for Heartburn.

ABSTRACT: BACKGROUND AND AIMS: Tegaserod is a selective serotonin receptor (5-HT(4)) agonist that relieves dysmotility symptoms associated with constipation. Here we explore its effects on functional dyspepsia symptoms and heartburn during continued proton pump inhibitor (PPI) treatment. METHODS: In this multicenter pilot study, following a 2-week screening/baseline period, women with functional dyspepsia and persisting heartburn treated with PPIs received add-on open-label tegaserod 6 mg twice daily (bid) for 4 weeks. Treatment responders were then randomized 1:1 to continue double-blind tegaserod or placebo therapy for 6 weeks. Efficacy variables included the proportion of days with satisfactory relief of dyspepsia symptoms (early satiety, postprandial fullness and bloating) as well as the change in individual symptom severity scores for these three cardinal dyspepsia symptoms. Health-related quality of life was evaluated using a validated questionnaire, the Nepean Dyspepsia Index. Adverse events (AEs) were monitored. RESULTS: Of 101 women enrolled, 71 completed open-label treatment, and 70 responders were randomized to double-blind treatment. The proportion of days with satisfactory relief of dyspepsia symptoms (least squares mean, LSM) increased with tegaserod and placebo, to 0.69 and 0.62, respectively at study end (P = 0.366). Similarly, both groups showed improvements in the composite daily symptom severity score (overall LSM change from baseline of 1.55 and 1.57, P = 0.934), and the Nepean Dyspepsia Index (overall LSM change of -39.0 and -37.8, P = 0.537). Tegaserod was well tolerated. Diarrhea was the most common AE (8.1% tegaserod, 0% placebo). There were no serious AEs or deaths. CONCLUSIONS: A significant treatment effect was not demonstrated in this study using a treatment-withdrawal methodology. In future studies of functional dyspepsia patients with heartburn, a more rigorous parallel-group study design should be considered.

Project description:BACKGROUND:The World Health Organization (WHO) recommends household contact investigation for tuberculosis (TB) in high-burden countries. However, household contacts who complete evaluation for TB during contact investigation may have difficulty accessing their test results. Use of automated short-messaging services (SMS) to deliver test results could improve TB status awareness and linkage to care. We sought to explore how household contacts experience test results delivered via SMS, and how these experiences influence follow-up intentions. METHODS:We conducted semi-structured interviews with household contacts who participated in a randomized controlled trial evaluating home sputum collection and delivery of TB results via SMS (Pan-African Clinical Trials Registry #201509000877140). We asked about feelings, beliefs, decisions, and behaviors in response to the SMS results. We analyzed the content and emerging themes in relation to the Theory of Planned Behavior. RESULTS:We interviewed and achieved thematic saturation with ten household contacts. Nine received TB-negative results and one a TB-positive result. Household contacts reported relief upon receiving SMS confirming their TB status, but also said they lacked confidence in the results delivered by SMS. Some worried that negative results were incorrect until they spoke to a lay health worker (LHW). Household contacts said their long-term intentions to request help or seek care were influenced by perceived consequences of not observing the LHW's instructions related to the SMS and follow-up procedures; beliefs about the curability of TB; anticipated support from LHWs; and perceived barriers to responding to an SMS request for further evaluation. CONCLUSION:Household contacts experienced relief when they received results. However, they were less confident about results delivered via SMS than results delivered by LHWs. Delivery of results by SMS should complement continued interaction with LHWs, not replace them.
