Safety and Feasibility of Using the Second-Generation Pillcam Colon Capsule to Assess Active Colonic Crohn's Disease.

BACKGROUND & AIMS: The second-generation Pillcam Colon Capsule Endoscope (PCCE-2; Given Imaging Ltd, Yoqneam, Israel) is an ingestible capsule for visualization of the colon. We performed a multicenter pilot study to assess its safety and feasibility in evaluating the severity of Crohn's disease (CD). METHODS: In a prospective study, 40 patients with active colonic CD underwent PCCE-2 and optical colonoscopy procedures. Using both techniques, we generated values for the Crohn's Disease Endoscopic Index of Severity (CDEIS), the Simple Endoscopic Score for CD, and global evaluation of lesion severity. In the first stage of the study, we calculated the correlation between PCCE-2 and optical colonoscopy scores. In the second stage, we performed interobserver agreement analysis for a random subset of 20 PCCE-2 recordings, graded in duplicate by 2 independent readers. RESULTS: There was substantial agreement between PCCE-2 and optical colonoscopy in the measurement of the CDEIS (intraclass correlation coefficient [ICC], 0.65; 95% confidence interval [CI], 0.43-0.80). There was substantial interobserver agreement between 2 independent PCCE-2 readers for the CDEIS (ICC, 0.67; 95% CI, 0.35-0.86) and the Simple Endoscopic Score for CD (ICC, 0.66; 95% CI, 0.32-0.85). However, the PCCE-2 scoring systematically underestimated the severity of disease compared with optical colonoscopy; based on our results, PCCE-2 detected colonic ulcerations with 86% sensitivity and 40% specificity. No adverse events were observed and PCCE-2 was better tolerated than colonoscopy. CONCLUSIONS: PCCE-2 is feasible, safe, and well tolerated for the assessment of mucosal CD activity in selected populations. Larger studies are needed to assess its operating characteristics further.

The JDRF CCTN CGM TIME Trial: Timing of Initiation of continuous glucose Monitoring in Established pediatric type 1 diabetes: study protocol, recruitment and baseline characteristics.

BACKGROUND: Continuous glucose monitoring (CGM) has been shown to improve glucose control in adults with type 1 diabetes. Effectiveness of CGM is directly linked with CGM adherence, which can be challenging to maintain in children and adolescents. We hypothesize that initiating CGM at the same time as starting insulin pump therapy in pump naïve children and adolescents with type 1 diabetes will result in greater CGM adherence and effectiveness compared to delaying CGM introduction by 6 months, and that this is related to greater readiness for making behaviour change at the time of pump initiation. METHODS/DESIGN: The CGM TIME Trial is a multicenter randomized controlled trial. Eligible children and adolescents (5-18 years) with established type 1 diabetes were randomized to simultaneous initiation of pump (Medtronic Veo©) and CGM (Enlite©) or to standard pump therapy with delayed CGM introduction. Primary outcomes are CGM adherence and hemoglobin A1C at 6 and 12 months post pump initiation. Secondary outcomes include glycemic variability, stage of readiness, and other patient-reported outcomes with follow-up to 24 months. 144 (95%) of the 152 eligible patients were enrolled and randomized. Allowing for 10% withdrawals, this will provide 93% power to detect a between group difference in CGM adherence and 86% power to detect a between group difference in hemoglobin A1C. Baseline characteristics were similar between the treatment groups. Analysis of 12 month primary outcomes will begin in September 2014. DISCUSSION: The CGM TIME Trial is the first study to examine the relationship between timing of CGM initiation, readiness for behaviour change, and subsequent CGM adherence in pump naïve children and adolescents. Its findings will advance our understanding of when and how to initiate CGM in children and adolescents with type 1 diabetes. TRIAL REGISTRATION: ClinicalTrial.gov NCT01295788.

Economic, clinical, and quality-of-life outcomes associated with olanzapine treatment in mania. Results from a randomized controlled trial.

INTRODUCTION: The objectives of this study were to determine the economic, clinical, and quality-of-life outcomes associated with olanzapine treatment in patients diagnosed with mania. METHODS: Patients with a diagnosis of bipolar I disorder with manic or mixed episodes were enrolled in a randomized controlled trial. The study design comprised a 3-week acute phase followed by a 49-week open label extension. In the open label extension, the use of lithium and fluoxetine was permitted for patients who experienced breakthrough symptoms. Clinical, economic, and quality-of-life outcomes of treatment were assessed. RESULTS: During the acute phase, olanzapine patients experienced a statistically significant greater mean improvement from baseline on the Y-MRS total score compared to the placebo patients. In the open label extension, patients experienced a statistically significant mean change of 11.8 units on the Y-MRS from the end of the acute phase. When compared to costs incurred in the previous 12 months of therapy, patients experienced savings of almost $900 per month during the 49 weeks of olanzapine therapy. These cost savings were largely driven by reductions in in-patient costs during the open label extension. Health-related quality of life improvements measured by the SF-36 were seen on several dimensions both in the 3-week acute phase as well as in the 49-week open label extension. CONCLUSION: From a clinical, economic, and quality-of-life outcomes standpoint, olanzapine had a significant impact in the treatment of mania, and could be considered a cost-effective treatment option for use in this population if these findings are extrapolated to non-clinical trial populations.
