RESUMEN

Probiotics have been suggested to be effective for functional dyspepsia, but their effect on gastric motility is not clear. We evaluated the effect of Lactobacillus gasseri OLL2716 (LG21 strain) on mild to moderate delayed gastric emptying by a double-blind, parallel-group, placebo-controlled, randomized trial. Participants (n = 28) were randomly assigned to ingest LG21 strain-containing yogurt (LG21 strain group) or LG21 strain-free yogurt (placebo group) for 12 weeks. The 13C gastric emptying breath test was performed to measure the gastric emptying rate over time following ingestion of a liquid meal, and the time to reach the peak (Tmax) was used as an indicator of gastric emptying. We also measured the salivary amylase concentration, an indicator of autonomic dysfunction under stress. The per-protocol population (n = 27, male n = 4, female n = 23) was evaluated for efficacy. When a ≥30% reduction in the difference between participant's Tmax and the Japanese mean Tmax was defined as an improvement, the odds ratio of improvement in delayed gastric emptying compared to placebo after 12 weeks was 4.1 (95% confidence interval, 0.8 to 20.2). Moreover, salivary amylase concentrations were significantly lower than in the placebo group, indicating an improvement in autonomic function. The present data were not enough to support the beneficial effects of the LG21 strain on delayed gastric emptying. However, if we define the odds ratio in further study investigated with a larger number of participants, LG21 strain might be expected to have some impact on delayed gastric emptying.

RESUMEN

BACKGROUND: Epidemiological studies have shown that dairy product consumption is beneficial for cognitive function in elderly individuals. ß-lactolin is a Gly-Thr-Trp-Tyr lacto-tetrapeptide rich in fermented dairy products that improves memory retrieval, attention, and executive function in older adults with subjective cognitive decline and prevents the pathology of Alzheimer's disease in rodents. There has been no study on the effects of ß-lactolin on neural activity in humans. OBJECTIVE: We investigated the effects of ß-lactolin on neural activity and cognitive function in healthy adults. METHODS: In this randomized, double-blind, placebo-controlled study, 30 participants (45-64 years old) consumed ß-lactolin or placebo for 6 weeks. Neural activity during auditory and language tasks was measured through 64-channel electroencephalography. Moreover, verbal fluency tests were performed at baseline and after 6 weeks. RESULTS: The ß-lactolin group had a significantly higher P300 amplitude at the Cp2 site (a part of the parietal lobe near the center of brain, p = 0.011), and C4 site (the area between the frontal and parietal lobe, p = 0.02) during the auditory tasks after 6 weeks than the placebo group. Thus, ß-lactolin supplementation promoted neural activity in the parietal area, which increases concentration and attention during auditory cognitive tasks. Compared with the placebo group, the ß-lactolin group also showed significant changes in the scores of verbal fluency test after 6 weeks (p = 0.033). CONCLUSION: Our findings provide insight into the mechanisms underlying the effects of ß-lactolin on attention in healthy adults.

RESUMEN

PURPOSE: Due to the burden of COPD in Japan, new pharmacologic treatments are needed to meet patient requirements. This study assessed the efficacy and safety of glycopyrronium (GP) delivered via metered dose inhaler (MDI) in Japanese patients with moderate-to-severe COPD. METHODS: This Phase IIb, multicenter, randomized, double-blind, 7-day, crossover study compared GP MDI 28.8, 14.4, and 7.2 µg with placebo MDI (all administered as two inhalations, twice daily). The primary endpoint was change from baseline in morning pre-dose trough forced expiratory volume in 1 second (FEV1) on Day 8. Secondary endpoints included FEV1 area under the curve from 0 to 2 hours (AUC0-2) and peak change from baseline in FEV1 on Days 1 and 8 and forced vital capacity AUC0-2 on Day 8. Safety was also assessed. ClinicalTrials.gov Identifier: NCT03256552; http://www.ClinicalTrials.gov. RESULTS: Sixty-six patients were randomized and 62 were included in the modified intent-to-treat population (mean age 67.5 years). All three GP MDI doses significantly improved change from baseline in morning pre-dose trough FEV1 on Day 8 compared with placebo MDI (least squares mean differences 108-131 mL; all p<0.0001). Significant improvements in secondary efficacy endpoints were also observed for all three GP MDI doses compared with placebo MDI (all p<0.0001). Dose-response plateaued at GP MDI 14.4 µg. No significant safety findings were observed with any GP MDI dose or placebo MDI. CONCLUSIONS: The results of this study suggest that GP MDI 14.4 µg (7.2 µg per inhalation) is the most appropriate dose for use in Phase III studies in Japanese patients with moderate-to-severe COPD.

RESUMEN

OBJECTIVES: To determine whether febuxostat with stepwise dose increase is as useful as colchicine prophylaxis in reducing gout flares during the initial introduction of urate-lowering therapy in patients with gout in comparison with febuxostat with no dose titration. METHODS: In this prospective, multicentre, randomised open-label comparative study, patients were randomised to group A (stepwise dose increase of febuxostat from 10 to 40 mg/day), group B (fixed-dose febuxostat 40 mg/day plus colchicine 0.5 mg/day) or group C (fixed-dose febuxostat 40 mg/day) and observed for 12 weeks. Gout flare was defined as non-steroidal anti-inflammatory drug use for gout symptoms. RESULTS: A total of 255 patients were randomised, and 241 patients were treated. Among the treated patients, gout flares were experienced by 20/96 (20.8%) in group A, 18/95 (18.9%) in group B and 18/50 (36.0%) in group C. The incidence of flare was significantly lower in groups A and B than that in group C (P=0.047 and P=0.024, respectively), although the differences were not significant after correction for multiple comparisons. No significant difference was noted between the incidence of gout flare in groups A and B. CONCLUSIONS: Our data suggested that stepwise dose increase of febuxostat and low-dose colchicine prophylaxis effectively reduced gout flares in comparison with fixed-dose febuxostat alone. Stepwise dose increase of febuxostat may be an effective alternative to low-dose colchicine prophylaxis during the introduction of urate-lowering therapy. TRIAL REGISTRATION NUMBER: UMIN 000008414.

RESUMEN

INTRODUCTION: Dapagliflozin is a selective sodium glucose co-transporter 2 inhibitor that improves glycemic control and reduces body weight and systolic blood pressure in patients with type 2 diabetes mellitus (T2DM). Dapagliflozin is effective and well tolerated over 12-24 weeks in Japanese patients with T2DM. In this study, the safety and efficacy of dapagliflozin administered as monotherapy and combination therapy were assessed over 52 weeks in Japanese patients with T2DM. METHODS: This was a 52-week open-label Phase 3 study consisting of a single treatment arm with no comparator. Dapagliflozin was administered as monotherapy (n = 249) or combination therapy (n = 479) with existing antihyperglycemic agents (sulfonylurea, glinides, metformin, alpha-glucosidase inhibitors, thiazolidinediones, dipeptidyl peptidase-4 inhibitors, or glucagon-like peptide-1 receptor agonists) to Japanese patients with T2DM and inadequate glycemic control for 52 weeks. Treatment with dapagliflozin was initiated at 5 mg/day and titrated to 10 mg/day as required. RESULTS: Dapagliflozin administered as monotherapy or combination therapy was well tolerated. The frequency of adverse events (AEs) over 52 weeks was similar between monotherapy (79.1%) and combination therapy (72.4%) groups, and AEs were mostly mild or moderate. The incidence of hypoglycemia at 52 weeks was 2.4% in the monotherapy group and 4.0% in the combination therapy group. In patients receiving dapagliflozin as monotherapy or combination therapy, reductions from baseline to week 52 were observed in glycosylated hemoglobin (HbA1c) (-0.7% in both groups), weight (-2.6 and -2.1 kg, respectively), and systolic blood pressure (-5.2 mmHg and -3.9 mmHg). In patients with insufficient response to 5 mg/day, dapagliflozin was increased to 10 mg/day, and a further decrease in HbA1c from the pre-titration value was observed in both groups. CONCLUSION: Dapagliflozin was well tolerated and effective as monotherapy or combination therapy in Japanese patients with T2DM over 52 weeks.
